INTRODUCTION 1.1 Like bush fires, which never really die out but burn beneath the surface and can flare up again at any time, the question of whether and in what sense there was a Keynesian revolution in British economic policy after the Second World has recently been rekindled by Booth (2001a) in a further bout of controversy in the Economic History Review. This eruption looks but a limited affair as only one of the half dozen or so participants of the major debates of the 1980s and 1990s (described by Booth as ‘new revisionists’) has chosen to respond (Peden 2003), leaving Booth (2003) in his rejoinder somewhat unfulfilled as battle has not satisfactorily been rejoined. Figure 1 summarises the enormous literature that has been generated thus far on this debate since it began its modern phase with Howson and Winch (1977). 1.2 My purpose here is not to make a further contribution to that debate as currently constructed by Booth, though personally I see nothing amiss with the new revisionists having arrived at an understanding of Keynesian influence as fragmented and dependent on the precise definition of terms. I am somewhat less comfortable with our conclusions being represented as post-modern, being deeply averse to the literary turn that has infected history and some of the social sciences in recent years. However, if post-modern is taken as meaning that we have sought to capture the complexity of events and eschewed simplistic dichotomies between situations which are either Keynesian or not, then I can be content here also for there has been a gross overemphasis on dichotomies in the existing historiography of Britain during the 1950s and 1960s. §2. SOME CONCERNS ABOUT BRITISH ECONOMIC HISTORIOGRAPHY 2.1 Concern about simplistic dichotomies was a point made in an earlier paper with respect to this and other economic policy debates (Rollings and Middleton 2002), a paper in which we identified also that there has been too much compartmentalisation of debates and that too often their dynamic characteristics have been ignored, resulting in a preoccupation with static analysis which has been at the expense of understanding incremental change which arguably has always been the hallmark of British public policy. 2.2 We have some further concerns about the historiography of British economic policy during the Keynesian era which relate to its comparative ignorance of relevant developments in the literatures produced by historians of economic thought and political scientists. Of these, the fact that British economic historians do not ordinarily read the writings of historians of economic thought is probably the more serious, for it has a number of consequences. First, being unaware of contemporary advances in economic methodology as applied by the historians of thought, economic historians lack their rigor in considering the rise and fall of economic ideas and might be Figure 1 The Keynesian revolution in British economic policy literature, c.1977-2005 Phase 1. 2. 3. 4. 5. intermission 6. 7. Focus and key contributions Begins with an initial wave generated by Howson and Winch’s (1977) study of the 1930s Economic Advisory Council and Hutchison’s (1978, p. 155) much cited review thereof which proclaimed that it showed ‘that both the Treasury and the Bank were largely converted to “Keynesian policies” … at least a year before the publication of The General Theory’ (Cairncross 1977 provides a much more balanced review). Concerned with both Keynes’s influence before the war and the extent of Keynesian elements in postwar policy, this contained the first contributions by Peden (1980); Tomlinson (1981a) – part of a deeper methodological critique of the then current orthodoxies of modern British economic history (Tomlinson 1981b) – which brought forth responses by Smith (1982) and Schott (1982), along with a reply by Tomlinson (1982); and Middleton (1982; 1983). Scepticism about Keynesian influence is restored. This saw battle joined in earnest and the arena shifting to the Economic History Review as Booth (1983) made his initial contribution on this topic, arguing (p. 122) that the Treasury’s conversion to Keynesianism was completed by 1947. In sequence we then have Peden (1983; 1984), which did not directly address Booth (1983), and Tomlinson (1984) and Rollings (1985) which did. Booth (1984; 1985), responding to these papers, completes this stage of the debate. Middleton (1985) summarised the debate as then reached for the 1930s. Largely concerned with immediate postwar policy, beginning with Tomlinson’s (1987) continued scepticism about whether policy can genuinely be seen as Keynesian by c.1950, a position given added force by Rollings (1988), and concluding with Booth’s (1989a). Concurrently, after an early contribution on the politics of Keynesianism (Clarke 1983), Clarke’s (1988) detailed study of the making of the Keynesian revolution seemed to settle this stage of the debate for the 1930s Overlap with 4. above: initiated by Booth (1987) which disputed the then emerging consensus about the form and extent of Britain’s managed economy in the 1930s; it brought forth critical responses by Peden (1989) and Middleton (1989b) and a rejoinder from Booth (1989b) (see also Peden 1990; and Hall 1989 for important comparative work on the diffusion of Keynesianism). Meanwhile, at least one of these participants, tiring of the issue of whether there was a Keynesian revolution in policy, thought it prudent to revisit what Keynes actually said and therefore what the benchmarks ought to be, in the process abandoning the instrumentalist approach (Keynesianism as deficit-finance) in favour of an emphasis on the underlying philosophy of economic management and whether governmental objectives would have been recognisable to Keynes (Middleton 1989a; see also Skidelsky 1989; 1991). The debate now abates, and not a moment too soon according to Newton (1991) who identified diminishing returns. From the early 1990s onward the debate occasionally surfaces but is largely subsumed within the controversy about postwar consensus politics, with key contributions on the Keynesianism or otherwise of policy from Rollings (1994; 1996). Represented by studies which emphasised the durability of pre-Keynesian policy goals (price stability and balance-of-payments equilibrium) and the practical limits placed upon postwar Keynesian demand management by the conservative nature of the postwar settlement between government, capital and labour in relation to the struggle to understand and contain Britain’s relative economic decline (for example, Howson 1993; Middleton 1996; 1998). The ESRC-sponsored Whitehall programme of the 1990s also produces works which are relevant (in particular, Lowe and Rollings 2000). 8. 9. 10. The publication of the Robert Hall diaries (Cairncross 1989; 1991), Cairncross and Watts (1989) on the Economic Section and Cairncross’s (1992; 1996; 1997; 1999) diaries and other policy memoirs provided essential raw material for studying policy in practice, as did the opening up of the official papers for the 1950s and early 1960s, resulting in rather disparate work which to a greater or lesser extent engages with this debate: Ringe and Rollings (2000) on the establishment of the National Economic Development Council; Kelly (2002) on demand management; Burnham (2003) on exchange rate policy in the 1950s; and Newton (2004) on sterling and immediate postwar reconstruction; with Ringe et al (2004), which surveys the public records on economic policy during the Conservative years, 1951–64, summarising what is currently known. Peden (2004), which reprints key Treasury responses to the Keynesian revolution between the return to gold and his death, also provides a valuable resource for future study. Represented by a series of studies inspired by the social learning literature, and in particular the Keynesian plus policy iniatives of the early-mid 1960s and the paradigm shift from Keynesianism to monetarism in the mid-late 1970s, both of which of course assume a Keynesian revolution in policy in the first place: see Hall (1993); Pemberton (2003; 2004) and Oliver and Pemberton (2004). Finally, Booth (2001a; b) and his attack – in sequence– on the ‘new revisionists’ who are identified as Peden, Rollings, Tomlinson, Howson and Middleton. Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 5/32 ___________________________________________________________________________________ accused of being stuck in a sort of logical positivist time warp.1 Secondly, they seem also largely unaware of the considerable body of work done in recent years on the sociology and professionalisation of economics in the major countries, work orchestrated by A.W. Bob Coats.2 This is immensely relevant to policy and to the influence of economists as it concerns the existence of distinctive ‘national styles’ in economics (both theoretical and applied) and the extent to which they have been subjected to internationalisation and Americanisation since the Second World War. Thirdly, the debate as currently constructed is somewhat disembodied in that Booth’s test of Keynesianism in policy – ‘did policy conform to advice from the Keynesian economists in the Economic Section’ of the Treasury (Peden 2003, p. 118) – disconnects policy from the broader economics profession through the assumption that these are representative agents. Our second concern about the narrowness of reading by most British economic historians relates to their innocence of much relevant work being undertaken by political scientists. Admittedly, the ESRCsponsored Whitehall programme did bring historians and political scientists closer together, and some have seen the potential offered by the social learning model (Pemberton 2004) whilst others have generated new insights using the ‘fragmented polity’ thesis to understand why modernisation programmes of the 1950s and 1960s did not fulfil their promise (Lowe and Rollings 2000), but there is other work on ideational change which has not yet been incorporated (for example, Blyth 2002). §3. PURPOSE AND PLAN OF THIS PAPER 3.1 Look to the economists 3.1.1 Having asserted that the extent or otherwise of Keynesianism in policy must be located back in the British economics profession itself, we are led necessarily to question whether research has hitherto been appropriately focused within the outputs of economists. Working from the pre-existing challenge to the debate as currently constructed, namely our scepticism that demand management be the sine qua non of Keynesianism, this paper adopts the position that if we are to more fully comprehend the Keynesian era in British economics and economic policy we must look to the supply-side as much as to the demand side, to microeconomics as much as to macroeconomics, and above all to the underlying preferences. philosophies and professional norms of mainstream British economics at this time. Thus our purpose here is to explore postwar economics and policy not through the filter of this now rather sterile Keynesian revolution in policy debate but in terms of the more fundamental characteristics of mainstream British economics and how these framed policy advice and practice during the Keynesian era. (Given the workshop focus we shall try and relate this as much as possible to the welfare state, though as will become evident there are good reasons why for the economists this is not as easy as it might appear at first sight.) 1 2 As for example, Blaug (1992) and variously Backhouse (1998), an ‘unrepentant Popperian’; Hands (2001), broadly supportive of post-Popperian developments; and Dow (2002), an exponent of methodological pluralism. An element of these methodological debates has been whether there can be ‘truth and progress’ in economics, upon which see Backhouse (1997b) and Boehm et al. (2002). See Coats (1997; 2000), the product of significant international collaboration and building upon his earlier studies of economists in government and in international organisations (Coats 1981; 1986). Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 6/32 ___________________________________________________________________________________ 3.1.2 Potentially, of course, such a project is an enormous undertaking, but for the purposes of this paper we activate two shortcuts: the first, in revisiting an under-utilised source for what it may illuminate about mainstream British economics; and the second, in casting a sceptical eye over the dominant strand of the historiography which assumes an end to the Keynesian era3 amidst the stagflation of the 1970s as the Keynesian conventional wisdom was variously challenged and then overwhelmed by monetarism and the new-classical macroeconomics, etc. 3.2 Constructing an advocacy coalition 3.2.1 It was central to those challenges as they played out in Britain that the agents for change attempted to construct an advocacy coalition which, in turn, first presented mainstream British economics as Keynesian and,4 secondly, sought to convince (or was it remind) the political agents for change that Keynesianism embodied certain core characteristics which were inimical to both optimal government size and scope and an efficient economy. To test their veracity we look at what is known about disciplinary attitudes during the 1970s, and in particular whether mainstream British economics was culpable of one or more of the serious charges made against it: 1. 2. 3. 4. 3 4 5 6 7 Was ‘there a recurring theme – that free markets will perform in an unsatisfactory way and give rise to unemployment and exploitation, externalities and social costs, inefficiency and excess’ such that ‘Massive government intervention is needed in order to ensure full employment, fair rewards, and the efficient allocation of resources’ as Walters (1978, p. 90) maintained in his attack on the false theories that had guided postwar policy.5 Was there a ‘presumption that pervades most of the mainstream literature on the rôle of government in economic life – the imposed social welfare function, and the myth of the omniscient and impartial government’ as O’Brien (1981, p. 64) argued in another IEA publication. Was there, and here Balogh6 was cited by name but there would have been other candidates, ‘a fringe of economists’ of influence who ‘regard all the laws of demand and supply as readily repealed for political purposes’, this another one of Walters’ (1978, p. 28 n1) complaints. And, even more emphatically, as one Centre for Policy Studies (CPS)7 pamphlet The beginnings of a written – as against oral – reaction to this is now becoming evident, with for example Jim Tomlinson set to give a paper at the April 2005 Economic History Society Annual Conference entitled ‘Tale of a death exaggerated: how Keynesian policies survived the 1970s’. There is a different strand to this literature by those who have argued that the supply-side reforms of the 1980s and 1990s wrought by the reaction against Keynesianism now make possible a revival of Keynesian demand management, albeit of a coarse rather than the fine-tuned variant of the 1950s and 1960s (for example, Skidelsky 1997). As in the syllogism then current ‘(a) Economic policy in Britain has been a failure. It has failed to improve our economic performance; (b) Economic policy has consisted of “Keynesian demand management”; (c) Therefore “Keynesian demand management” has been a failure.’ (Blackaby 1979, p. 185). This was the eighth Wincott Memorial Lectures, a series of high-profile Institute of Economic Affairs (IEA) sponsored attacks on the Keynesian conventional wisdom. The first of these was given by Friedman, being his ‘The counter-revolution in monetary theory’ (1970), which was enormously important in the diffusion of monetarist ideas to Britain. Subsequent lectures were by Meade, Jewkes, Hayek, Robbins, Jay and Peacock. Thomas Balogh along with Nicholas Kaldor attracted the ire of much business and City commentators, routinely being referred to as the ‘terrible twins’ or the ‘Hungarian goulash’: see George and Bewlay (1964), an Aims for Industry pamphlet. The CPS had been established in 1974 by Keith Joseph to ‘champion liberalism’ via ensuring that Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 7/32 ___________________________________________________________________________________ argued, was there a case to answer that such a willful disregard for commonsense policies amounted to treasonable conduct on the part of the Keynesian economics establishment (Pringle 1977). 3.2.2 The attack on Keynesian thus concerned much more than just demand management; it connected directly to the cardinal choice of political economy: that of government or market; or less dichotomously, of government and market. We thus examine what is known about the characteristics of the discipline for unity and divisiveness during the 1970s with respect to the fundamental concepts of welfare economics: of scarcity and choice, of economic efficiency, of the distribution of incomes and of market vs. government as allocational devices. Our source material will be a pioneering attitudinal survey of the autumn of 1971 which was conducted by Samuel Brittan (1973a) who at that time was just on the cusp of his ‘second thoughts’ on Keynesianism (Brittan 1975), for later in the decade his writings – in the Financial Times and elsewhere – would become enormously influential in the growing attack on the Keynesian conventional wisdom (see Brittan 2000 for his account of this period). We then use this attitudinal survey to connect to the more recent literatures on the defining characteristics of British economics. 3.2.3 Of course, the attack on Keynesianism in the 1970s was the culmination of a much longer process, having foundations in the widespread disillusionment with the economic record of the 1960s in which successive Conservative and Labour governments had tried to promote faster economic growth and had failed to do so. The British economics establishment were deemed at best complicit in this failure and at worst much more directly responsible as it was their hubris which drove the politicians onwards to ever more extravagant growth claims and ever less effective (and ultimately more damaging) policy interventions.8 In effect, in this stronger version they were the engine of Pollard’s Law: that ‘of the deterioration of British economic policies. Like the “average” Russian harvest (“worse than last year’s, better than next years”), every government seems to have done more damage and to have succeeded in fewer things than the preceding one’ (Pollard 1984, p. 165). 3.2.4 In an earlier paper (Middleton 2004) on policy-making and policy outcomes during the growth experiments of the early-mid 1960s I demonstrated that far from the key economic advisers being intoxicated with the ‘growth mania’ of the times (Clark 1961; Hutchison 1968, pp. 207––33; Arndt 1978) it was to the politicians that one should look for deeper explanation of the policy failures of that period. With the aid of the official documents recently available, together with the very full and not entirely self-serving memoirs of key policy agents (notably Cairncross 1996; 1997), we can see that the ‘representative agents’9 of the British economics profession were not imprudent about what growth targets were possible and what risks were bearable for inflation and the balance of payments. In short, we rejected the stronger version of the critique advanced by Hutchison (1968) and others about the pseudo-Keynesians and the damage they inflicted on the British economy, for in practice the economists acted as a break upon the wilder ambitions of the politicians and they provided 8 9 the next Conservative government elected no longer remained stranded on the middle grounded of consensus politics but could instead embark upon radical neo-liberal reforms. On this and the IEA, see Cockett (1994). Some of the strongest condemnation can be found in Hutchison (1968) and Sinclair (1972). In alphabetical sequence, but most definitely not an ordering of their respective influence on policy, this was a close study of the advice proffered by Balogh, Cairncross, Kaldor, MacDougall and Neild. Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 8/32 ___________________________________________________________________________________ broadly sensible mainstream advice. Where the economists did fail, however, is that economics at that time actually provided very little useable knowledge about how to increase growth. This current paper, which focuses a little later in the Keynesian era than the growth experiments, is offered as a further contribution towards rehabilitating the economists and saving them from the condescension and misrepresentation that they have endured at the hands of an anti-Keynesian advocacy coalition. Whilst this research is part of a continuing project demonstrating that the problems of the postwar British economy are more political than economic, and are to be found principally in the way in which political competition was highly dysfunctional for good economic policy, again we will examine so far as we can those aspects of these economists’ writings and policy advice which shed light on the fundamentals of contemporary mainstream welfare economics in Britain. A fuller version of this would, for example, explore property rights, regulation, monopoly, taxation, externalities and the environment, the tensions between the pursuits of social and economic objectives and the relative efficiency of public and private production. What is offered here is a very modest start towards that larger agenda. 3.3 Harry Johnson and what passes for economics in England10 3.3.1 Before proceeding, however, we need also to introduce a special class of critique: that of Johnson’s (1973a; 1975) condemnation of the British economics establishment, for he was a pioneer in seeking to identify and explain national styles in economics as well as being an important agent in his own right in the monetarist counter-revolution. Of course, we await Moggridge’s biography for the full story of his very particular disdain for British (more correctly, English; perhaps, just Cambridge!) economics, but we here begin with his contribution to the debate – which took place in Encounter – as a response to Postan’s (1968) charge that the British economy was suffering greatly from the malign influence of a plague of Keynesian economists. Johnson (1968) was actually on the economists’ defence team, but he was scathing about the lack of professionalism in British economics. Thus, it was: a great mistake, though a common one, to assume that governmental economic policy is really made in accordance with, or even much influenced by, the best that economic science has to offer. Instead, the government economist is more frequently a barrister making the best case for his client’s behaviour that he can.... This is true not only in England, but in the contemporary homeland of scientific (as contrasted with forensic) economics, the United States. The difference is that in the United States a pluralistic university system based on competition in academic excellence ... provides incentives for economists to base their careers on scientific accomplishment rather than political usefulness, to challenge forensic nonsense on scientific grounds rather than accept and repeat it out of a sense of responsibility to and personal participation in the power structure, and to relate themselves to government for the most part as scientifically qualified expert consultants rather than employees or general policy advisers. (Johnson 1968, p. 52) 3.3.2 For Johnson, the problem with poor policy quality in Britain lay not with the shortcomings of contemporary economics, but with the deficiencies of British economists. The inferences are clear, and the charge serious: British economists were both a product and a cause of the British disease, that shorthand term for the economic decline of Britain which encompasses a dysfunctional body politic, due in no small part to Oxbridge dominance and characterised by an obsession with class and with the cult of the amateur; successive economic policy mistakes; a contempt for production, science and technology and so on. More specifically, Johnson charged British 10 This section draws upon Middleton (1998, pp. 21-4). Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 9/32 ___________________________________________________________________________________ economics with being amateurish, in the sense of lacking a proper postgraduate programme of economics education and, as a consequence, unable to develop firm traditions of scientific progress. Particular ire was reserved for Oxbridge and the civil service, the former for its undue influence on British academe and the political classes; and the latter, together with the honours system, for its corrupting influences: The result is that academic economists are too easily bought, either as public and ostensibly impartial defenders of party and government policies or as expert advisers to and servants of government, willing to allow their reputations to sanction policies adopted contrary to their advice or to the prescriptions of their science in return for the opportunity to exercise some residual influence in some areas of policy-making. That residual influence, in turn, is frequently exercised, not by demonstrating superior competence in problem analysis, but by demonstrating superior ability to invent politically appealing economic policy gimmicks. (Johnson 1968, p. 52) 3.3.3 For Johnson (1975, p. 226), Keynes was ‘an exceptional economist when he lived, but .. a malevolent myth since he died.’ From this standpoint he then developed his five propositions of British establishment economics (Johnson 1975, pp. 222–5), ‘all of them connected with the career and the writings of ... Keynes - by which is meant, not what Keynes actually wrote and thought, but what Keynes is believed or construed to have thought (or would have thought, if he had understood his own theory) by his modern-day successors’: 1. 2. 3. 4. 5. ‘all economics in the main tradition of scientific economics is mere “orthodoxy”, and as such is to be despised and turned on its head by the clever economists,’ one implication of which was the ‘assumption that the more startling “unorthodox” a new proposition is, the more true it must be.’ ‘money cannot possibly matter - because Keynes triumphantly established this point against the barbarous forces of orthodoxy, and demolished the quantity theory once and for all.’ “‘full employment” is an exclusive definition of social well-being, and as such to be pursued at virtually any cost.’ ‘workers ought to be so grateful for the efforts of their intellectual and political superiors to give them the benefits of full employment that they will refrain from embarrassingly inflationary wage demands.’ ‘faster economic growth is the panacea for all England’s economic (and for that matter political) problems and that faster growth can easily be achieved by a combination of generally inflationary demand-management policies and politically appealing fiscal gimmickry.’ §4. ‘TAKING THE PULSE’: THE BRITISH ECONOMICS PROFESSION IN THE EARLY 1970S 4.1 A discipline in disarray? 4.1.1 In the early 1970s mainstream British economics, as in university economists and academic economics, faced three challenges: first, new economic problems and an intensification of existing ones, both domestic and international; second, rival views of how to understand these problems; and third, and most important, a revival of market-based (as in City of London and business) producers of economic commentary. As is well-known, the market for economic expertise in Britain has always been highly competitive, with the professionalisation of academic economics not being mirrored by anything resembling dominant producer status, and certainly Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 10/32 ___________________________________________________________________________________ not in terms of economic policy advice. 4.1.2 Peden (1996, pp. 171–2) has provided a useful taxonomy on the supply side of economic knowledge available to policy-makers: 1. 2. 3. 4. 5. information (diverse sources, official and non-official); practical experience, and especially knowledge that is sought and proffered by City agents on more than just financial matters; economic theory, principally but not exclusively the domain of academic economists; informed opinion, a key category which captures the wide policy networks in Britain of financial journalists, interest groups and individual members of the ‘establishment’ (in the Balogh sense); and realities of political economy, which I have described elsewhere as ‘a residual category which captures the “art of the possible in economic affairs”, and more particularly gives to the higher civil service their role as guardians of past experience and mediators of present constraints and possibilities’ (Middleton 1998, p. 51). 4.1.3 To take the pulse of the British economics profession is thus no easy matter, and particularly at this time when there was a major political issue confronting political elites and others participants: that of whether Britain should join the then EEC (now EU), upon which the profession was evenly divided as regards the potential benefitcosts of membership (Khan and Johnson 1972; Hutchison 1977, ch. 5; Middleton 1998, pp. 26-8). Concurrently, the Heath government had felt compelled to abandon its ‘Selsdon’ policies in face of mounting unemployment, resulting in a policy U-turn in 1971–2 – both macroeconomic and microeconomic in scope –which had enormous implications for the economy and for the credibility of Keynesian economics. Conditions were thus ripe for crisis, but as we turn to examine what is known about disciplinary attitudes towards fundamental economic issues at this time a rather different picture emerges. 4.2 Brittan ‘Is there an economic consensus’? (1973a) 4.2.1 Brittan (1973a) is pioneering work,11 though his probing of economists’ professional opinion had origins not in these growing concerns about the discipline, but in his having encountered some multiple choice test questions for economics undergraduates12 which provoked him to muse that the ‘correct’ answers ‘might cause surprise, disagreement or even indignation among many laymen and perhaps even some economists’ (Brittan 1973a, p. 5). This motivated him to survey the profession 11 12 The first US survey of US economists was Kearl et al. (1979). Needless to say this made no mention of Brittan’s (1973a) prior study, though this later study was methodologically much more advanced, and in particular we should note that Brittan’s processing of the questionnaires returned had involved a careful reading (including any accompanying explanations and elaborations) with his interpreting the results before tabulation. As he noted (Brittan 1973a, p. 25): ‘I shudder to think … what this enquiry would have yielded if it had been undertaken by the fashionable computerised methods, in which only rigidly pre-specified alternatives would have been digested by a literal-minded magnetic tape …’ The Economics Education Project was based at Heriot-Watt; see Attiyeh and Lumsden (1971) which must be one of the last papers published in an economics journal to carry in a footnote referring to its main statistical findings: ‘For readers unfamiliar with regression analysis, the regression coefficient indicates the change in the dependent variable that can be expected ceteris paribus from a change of one unit in an independent variable…’ (p. 85). Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 11/32 ___________________________________________________________________________________ to see how much general consent they might elicit and to test their professional responses against two reference groups keenly interested in public policy but without necessarily any specialist economic expertise. 4.2.2 The questionnaire was sent to just over 250 economists in the autumn of 1971, of which 117 were useable replies: comprising 44 academic economists, 37 members of the Government Economic Service (GES), 13 17 business economists and 15 others who could not be categorised by occupational type. In total, we might estimate the number of questionnaires dispatched as approximating to 20 per cent of the combined stock of academic economists, members of the GES and the Society of Business Economists.14 The two lay groups comprised Conservative (39) and Labour (52) MPs and political commentators (24) (useable responses in parentheses).15 4.2.3 The questionnaire totalled 19 questions divided into two sections: A and B, in part separated along micro-macro lines but also with part A subsequently sent to the two lay reference groups as it was expected that they would have relevant opinions. Part B was deemed to require at least a modicum of professional training and was therefore limited to the economists. The underlying principles of the exercise and the multiple choice format were obvious points for disputation amongst those who did not respond, and indeed many who did respond. The questions selected, and their wording, was also contentious, but hopefully it is less tendentious that to a greater or lesser extent they do address fundamental economic concepts which are of relevance to whether the British economics profession was so wedded to market failure and so dirigiste in instincts that the liberal market order was in peril. 4.2.4 Table 1 reports in abbreviated form the results for part A and Table 2 those for part B. Taking these in turn, in part A of the questionnaire, that with the microeconomic focus, there is a systematic pattern of the differences between economists being much less than the differences between economists and the two reference groups. These data are not subject to any quantitative analysis beyond that reported here, and in particular there is no use of entropy measures which are now routine in such exercises (as will be the case for the next substantial polling exercise on British economists: Ricketts and Shoesmith 1990; 1992). Nonetheless, had such analysis been undertaken we can be confident that the difference revealed in part A would be statistically significant. Turning to part B of the questionnaire, the macroeconomic questions, there was undoubtedly less agreement than on the microeconomics, but still sufficient common ground to belie the stronger versions of the ‘discipline in disarray’ school of 13 14 15 Defined as Whitehall departments, the Bank of England, NEDO and NIESR. Of the 37 in this category, about 30 could be directly regarded as responsible to Ministers, and of these about three-fifths were connected with the Treasury or had related responsibilities. The Chief Economic Adviser to the Treasury and Head of the Government Economic Service (Donald MacDougall) and his deputy (Bryan Hopkin) were not canvassed; ‘otherwise the Whitehall recipients covered a broad spread of ranks from junior to very senior positions’ (Brittan 1973a, p. 10). Booth and Coats (1978, tables 4–5) report 874 university teaching posts for 1971 and 268 professional economists in government, giving approximately a 5 per cent sample for the academics and 14 per cent for the governmental economists. Brittan (1973a, p. 9) tells us little about the academic group, save that he ‘thought it desirable to spare the holders of chairs at the ancient universities this particular form of inquisition’ A list is provided in his appendix 4 of the academic and business economists who consented to being publicly identified by name and institution/business employer. No attempt can be made to estimate the sample size for the commentators, but for the MPs it amounted to 14.4 per cent overall (Conservatives 11.8 per cent; Labour 18.1 per cent). The 1970 election results have here been used as the denominators: Butler and Pinto-Duschinsky (1971, p. 354).

The smog problem could be virtually eliminated if approximately 100 air-purification plants were built in the area. These plants would simply draw in smog-filled air, remove the smog, and pump the clean air back into the Central City atmosphere. It is estimated that the cost of operating each plant would be £25,000 per year 2 3 It is highly unlikely that private business firms would build and operate the plants and sell their services directly to individual residents of the Central City area because: b People are unlikely to be willing to pay for smog-free air. d It would be impossible to provide smog-free air to those willing to pay for it while withholding it from those who refuse to pay. Suppose that the government of the Central City were to build and operate the air purification plants. From the standpoint of achieving efficiency in the allocation of economic resources, which of the following taxes should be increased to provide the additional tax revenues needed to finance the operation of the air-purification plants? a Motor vehicle fuel c Property * * 4 Question As compared to direct social security payment, how would you evaluate the provision of below-cost public housing to poor persons from the point of view of satisfying consumer wants? a b 5 6 7 It is more efficient because it gives low income persons what they need. It is less efficient because it will result in too much housing and too little of the other things that consumers want. The most important economic function of rental payments for the use of land is to: b Influence how land will be used. d Assure an adequate supply of land in the society as a whole. Which, if any, of the following statements would be correct when applied to a private enterprise economy? a One of the principal effects of competition is to force prices to the lowest level consistent with normal profits. b One of the principal functions of profits is to indicate to the government where wages are too low. i. (a) only iv. neither (a) nor (b) In a free-enterprise economy, the presumed harmony between individual and public interest depends on: b Careful planning and co-ordination of economic activity. d Competitive markets and pursuit of self-interest by individuals.

If we take free enterprise to mean free price competition in the market, then even socialism cannot do without this enterprise. Only a few staples will have centrallyfixed prices. All others will be allowed to move freely in response to supply and demand.’ 8 9 This report of changes taking place in many of the Soviet bloc countries supports the view of many Western economists that: b A freely-operating market system can perform efficiently the function of allocating scarce resources to satisfy competing wants under socialism as well as under capitalism. c Socialism cannot work because it requires rigid central planning and unrealistic prices which cannot allocate resources efficiently. The bigger the volume, the lower the cost; that is the first law of all industry! Which of the following best describes this quotation? b Although not a scientific law, the statement embodies a well established generalisation applying to most products, but not to all of them. d Although true up to a point for virtually all products, the statement is inconsistent with a well-established finding of economics. 10 ‘The Selective Employment Tax (SET) in effect requires a non-manufacturing firm to pay a tax for each worker it employs. For these firms the SET can be expected, in the long run, to lead to an increase in output per worker.’ Is this statement correct or incorrect and why? b Correct, because a rise in labour productivity can be expected in the long-run when firms substitute other factors of production.

Although in practice much of the City/business critique conflated the concerns about empty formalism with frustrations that disciplinary agreement on macroeconomics was breaking down into wars between rival camps of economists (crudely monetarists vs. Keynesians), it was the case that by the mid-1970s a generalised crisis of confidence in economics was apparent. Coats (1988, p. 219) refers to the ‘collective “self-flagellation of these years, a reflection of professional and public concern following the ending of the Keynesian hegemony (c.1945–1965), and … a reaction from the collective hubris and exaggerated claims of that era.’ 4.2.5 Brittan’s interpretation of these results was, of course, directed at determining the extent of agreement amongst economists and whether there was any dissonance as between the economists and the two lay reference groups. However, as can be seen from the nature of the questions and of the pattern of responses, there is potential here to reveal the economists’ attitudes for a different objective: that of assessing whether the British economics profession displayed any of the – according to its critics – malign views about such fundamentals as the primacy of the market and of the price mechanism. After all, the questions in part A were calibrated to illuminate the economists’ responses to questions which entailed application of the key instruments in their professional toolkit which, of course, comprise the fundamentals elements of economics: those of scarcity and choice, efficiency, distribution and market failure. 4.2.6 Viewed in this light, about 75 per cent of the economists who responded subscribed to what Brittan (1973a, p. 21) termed the ‘liberal economic orthodoxy’: ‘that competitive markets and the pursuit by individuals of their own interests can – with definable exceptions – produce an effective and prosperous economic system, and a reasonable harmony between public and private interest.’ On market failure, he noted further that the evidence was from this survey that British economists’ preferred solution for externalities was through adjusting relative prices through taxes and subsidies rather than by direct controls or regulations. Thus on efficiency and equilibrium we have an image of orthodoxy, but what about equity? Here we obviously enter more normative terrain, and Britain says of the questionnaire responses: A large number of economists, even among those who voted fairly solidly for the liberal orthodox ticket, showed an extreme pre-occupation with the distribution of income – arguably outrivalling that of many Labour MPs. An impressionistic judgment is that their egalitarian concern is greater than among economists in most other Western countries, and greater than that of almost any other British middle class professional group outside the social services. (Brittan 1973a, pp. 22–3) 4.2.7 He tentatively connected such egalitarianism to the puritan legacy17 and also located a more immediate antecedent in Alfred Marshall. Subsequent cross-national survey evidence, reported in Table 3, confirms a possible British distinctiveness in this respect. Certainly, for Johnson (1973b) British economics and politics suffered from 16 17 For the RES, Worswick (1971) was certainly pretty glum, Phelps Brown (1972) less so, but see by contrast MacDougall (1974) who made the important point that the cacophony against economists coincided with a period in which the demand for economists has risen very substantially. Contemporaneously, he was working on his Capitalism and the permissive society (Brittan 1973b) which was developing the efficiency and equity arguments for the free market.

Whether naïve or not, it is probable that this national preference is connected with another characteristic of British economics during the Keynesian era: the allegiance to very low levels of unemployment, and certainly much lower than Keynes (or even Beveridge) had thought possible (Kahn 1976, p. 30; see also Hutchison 1976, p. 61). But, of course, the whole postwar welfare state had been built on the basis of Beveridge’s assumption C (HMSO 1942, para 440): that of full employment. This constituted an interlocking system whereby, on the supplyside, full employment boosted national income and thus, for any given tax ratio, the resources to finance welfare expenditures, whilst on the demand-side, low levels of unemployment reduced the demand for welfare expenditures, both directly on unemployment benefits and indirectly through the association of primary poverty with unemployment. The breakdown of this calculus in the 1970s is central to explanations of the crisis of Keynesian social democracy (Middleton 1996, p. 474). 4.2.8 Such income redistribution preferences might be seen as Keynesian, but only insofar as Keynes and Beveridge were engaged in the common task of redefining liberalism so as to ensure the survival of a market order which whilst no longer laissez-faire was still largely unregulated. For Cutler et al. (1986, p. 9) this redefinition produced the following demarcation between government and market: (i) (ii) (iii) (iv) (v) 4.2.9 Certain basic conditions of social life have to be ensured. Poverty and economic insecurity, for example, are dysfunctional and may ultimately threaten the existence of the capitalist order. The maintenance of these conditions of social life is impossible on the free market if a policy of strict laissez-faire is pursued. The control of poverty, for example, requires some form of state social security and so does the curbing of insecurity. State intervention is not undesirable but imperatively necessary. This is because norms on the basic conditions of social life cannot be maintained without some form of state intervention. State intervention should be minimal and confined to what is necessary. Intervention should be circumscribed in nature and extent so that there is as little interference as possible with the valuable political and economic freedoms of capitalism. State intervention should be directed so that it suppresses basic capitalist freedoms only so as to re-establish the conditions of their effective functioning (elsewhere). Classically, for example, with state regulation established in one sphere of the economy, unregulated market choice can flourish elsewhere. The economists’ preferences thus inevitably have a political dimension, but are they nationally distinctive and in particular with respect to the US? Certainly, we might hypothesis that during the Keynesian era it is possible that British economics was distinctive from American economics because the politics of the median British economist was to the left of their American counterpart, though we have no direct evidence for this.18 What we do know is that notwithstanding the growing 18 Backhouse (2000, p. 22) cites evidence from Halsey (1992, p. 237) on the leftward shift in academics’ political allegiances between the 1960s and the 1980s, but this is not differentiated by discipline. Halsey’s earlier work (Halsey and Trow 1971, p. 429), derived from questionnairebased research conducted during 1964–6 as an offshoot of the Robbins report, asked ‘Is there a causal relation between academic subjects and political outlook?’ They obtained evidence that social scientists were ‘well to the Left of all the other’ academic groups, with two-thirds of social scientists being Labour Party supporters. Although this result partly reflected social class origins, the difference in political preferences between subjects was statistically robust (p. 431). Unfortunately, they did not separately identify disciplines within the social sciences. We also lack cross-country evidence, though they do cite (p. 429 n.1) Lipset (1963, pp. 336–8) on ‘evidence for the Leftism of American social scientists.’ Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 21/32 ___________________________________________________________________________________ Americanisation of British economics, that different market conditions resulted in British economists sharing with their European counterparts a greater propensity to develop national knowledge and to participate more fully in national affairs (Frey and Eichenberger 1993); that there was greater production and consumption of heterodox ideas; and that British economists have made particular contributions in fields such as the measurement of inequality and in public economics (Backhouse 1997a, p. 58) which support Brittan’s survey evidence. Moreover, to judge from Rickett and Shoesmith’s (1992, pp. 211–12) later survey, these differences seem enduring. 4.2.10 Turning next to the politicians’ responses, the difference between their views and the economists may reflect inadequate knowledge on the part of either side, different normative positions or different conceptual equipment. Look, for example, at question 1 in Table A where 88 per cent of the economists favour using the price mechanism as a short-term rationing device as against only 35 per cent of Conservative MPs whose ideology presumably made them more predisposed to favour market solutions. Question 4, that on housing, also revealed a very significant gap between MPs (whether Conservative or Labour) and the economists on the efficiency of subsidies for the poor. There are some predictably ideological responses, as for example in question 8 where the Conservative and Labour MPs are hugely apart in their opinion on the potential efficacy of socialism (see 8c). The strength of Conservative antipathy did not surprise Brittan (1973a`, p. 56), nor Labour’s modal response (8a) which led him to comment ‘The cause of any sort of market oriented social democracy has still made painfully little headway in the British Labour Party, even at the Parliamentary level.’ 4.2.11 It is unfortunate for our purposes that Brittan’s survey did not delve deeper into the sort of areas that are now routine in the literatures on welfare states’ impacts on economic growth via inefficiencies and disincentives, though the fact that he did not suggests something about the limited measure of economists’ concern about the possible ill effects at this date relative to later in the decade. Of course, the modern literature is somewhat inconclusive on whether large welfare efforts ‘cause’ or are the consequence of slow growth,19 and it must be remembered that the size of Britain’s public sector, its tax levels and characteristics and the extent of its welfare effort by the early 1970s were often gravely misrepresented by those of the emerging New Right: the reality was that by Western European standards, on tax and welfare Britain was decidedly average, though obviously more developed than the US which here, as in so much else in economics and public policy, is a misleading comparator (Middleton, 1996, ch. 11). Indeed, as is clear from Table 4 on social expenditures as a percentage of GDP, one of the routine summary measures used in this debate (for example Atkinson 1999, figure 2.2), Britain went from having the highest welfare effort of the G-7 just before the Second World War to being the median country of the OECD by 1970 as other countries underwent a catch-up process. Figure 2, another routine presentation in this debate, also shows that in terms of social transfers and GDP/capita, there was nothing distinctive about the British case by 1970. 19 The modern phase of indicting the welfare state for slow growth can be dated to the 1993 Lindbeck Commission report which was prompted by the crisis of the ‘Swedish model’ of social solidarity through a high redistributive effort; on this see ‘Controversy: economists, the welfare state and growth: the case of Sweden’, Economic Journal, 106 (November 1996), pp. 1725–79; and for a balanced assessment of the cross-country economic evidence that welfare states are a barrier to high economic growth, see Atkinson (1995, ch. 6; 1999).

In histories of welfare policy, the economists appear as tool-makers for judging efficiency and equity, but otherwise are not present (for example, Lowe 2005). We thus know little Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 23/32 ___________________________________________________________________________________ of the profession or of its leading figures in this respect. We know more about some of the canonical figures in the social policy field who used economic analysis to justify a large welfare effort, most notably Richard Titmuss,20 and we know also that in Britain social policy analysts were significant drivers for egalitarianism. But as things currently stand, it is the politicians and the commentators, not the economists, whose economics is more dirigiste and/or potentially autistic with respect to the fundamentals of welfare economics. §5. BRITISH ECONOMISTS, THE WELFARE STATE AND TAXATION 5.1 In the 1950s and 1960s few British economists were specifically interested in the welfare state, believing that the combination of full employment, rising real wages and an enhanced social welfare transfers had eradicated the poverty that had motivated an earlier generation to become economists in the first place and natural supporters of the Keynes-Beveridge managed-mixed economy and welfare state that emerged after the second World War. Social security was thus a topic which could be left to the social policy analysts, with for example it being rare for a paper to appear in the Economic Journal (EJ) or American Economic Review on the subject of the welfare state (Atkinson 1999, p. 3). Atkinson is undoubtedly right about the EJ which, on the old Journal of Economic Literature (JEL) subject classification for welfare, health and education (910), carried a grand total of only 12 papers between 1942, the publication of the Beveridge report (HMSO 1942), and 1973. As can be seen from Figure 3, drawn from the 10 per cent sample of the EJ’s contents that I undertook for my Charlatans or saviours? (Middleton 1998), the 900 class is dwarfed by papers in the old JEL classes 000, 100 and 400 over the Keynesian era. 5.2 The connection between economists and welfare thus lies more with macro- and microeconomic policies which impact on growth, employment and price stability (pace the importance of Beveridge’s assumption C), all of which of course had important distributional impacts. It was this dimension, as much perhaps as any ethical inheritance from Marshall’s mission for the professionalisation of British economics (that economists must do good as well as be scholastic), which underpinned the British profession’s preoccupation with issues of income and (less so) wealth distribution. Concurrently, of course, we can detect for the 1950s and 1960s an elite ambivalence about the desirability of growth which we can trace to Keynes and to his well-known essay, ‘Economic consequences of our grandchildren’ (1930). This is typically read as a thoroughly Bloomsbury21 document in which, by 2030, the economic problem would be solved as material abundance abounded and human beings would be able to delight in their bountiful leisure and the dominance of non-pecuniary activities. For the interwar generation of British economists their professional task was to help engineer, first, full employment and, second, a lessening of income and wealth inequalities. This latter objective was partly ethical and partly practical in terms of raising the average propensity to consume to counter any inherent tendency towards secular stagnation. 20 21 Most recently by Reisman (2004); see also the three commentaries on this paper. Skidelsky (1992, p. 237) notes that this essay ‘has attracted little attention from economists, perhaps rightly’ but none the less proceeds to devote a number of pages to its exposition because it ‘sums up many of the ambivalences in Keynes’s own thinking and psychology’, not least on the educated bourgeoisie’s ambivalence about business.

Harrod, the father of growth theory and the most vocal critic of ‘Stop-Go’, was constantly pressing for further sustained expansion because of his distaste for the waste of the Stop phase and his concern that without growth promotion ‘the United Kingdom may sink down and fail to play the part that could be so important for sustaining the strength and growth of the free world.’ (Harrod 1963, p. 207; 1967). Joan Robinson, Kaldor and Meade can also be portrayed in a similar light, although none of them espoused Harrod’s preoccupation with national decline. Robinson and Kaldor would, of course, be active in the Cambridge capital controversy, though they would differ substantially in their engagement with current policy concerns with the latter’s diagnosis of incipient deindustrialisation as the cause of slow growth (Kaldor 1966) and his proposals for tax reform to stimulate the manufacturing sector being decisive for the 1964–6 Labour government (Thirlwall 1989; Pemberton 2001). At first sight the capital controversy appears remote from the politicians’ preoccupation with raising the growth rate, but since it concerned a different – non-neo-classical – vision of how the capitalist system functioned which emphasised the way in which output movements affected wage and profit shares, the issue of the distributional consequences of the growth process was actually to the fore. 5.4 Meade’s interests were more centrally macroeconomic (how to simultaneously achieve internal and external equilibrium) but also more wide-ranging.22 In particular, as I argued in Charlatans or saviours? (Middleton 1998, pp. 168–71), he – as his hero Keynes – embodied the ethical imperative in his economics that was a hallmark of Marshall’s mission for the professionalisation of British economics. Avowedly of the political left, but always mindful of what could be achieved by government and what must remain the domain of the market, his was a search for a ‘middle way’ between collectivism and capitalism which would strengthen the potential efficiency properties of the former without sacrificing the degree of equity and equilibrium that was desirable for durable social democracy. 5.5 This, of course, returns us to the politics of the Keynesian era. Similarly, it is to politics that one must look for what must be a central element in any fuller discussion of distributional issues, namely the higher taxation levels that were characteristic of this period compared with before the Second World, and personal taxation in particular. Figure 4 provides a longer-run context for the very high standard and highest marginal rates that were characteristic of the income tax from the end of the Second War through to the late 1970s. Clearly, this is but one window into this part of the fiscal system, and we need to acknowledge that all other OECD countries experienced similar trends, but any fuller study would want to examine the writings of mainstream economists on the rates and structure of taxation at this time. Certainly, for some the incoherence of the British tax system by the late 1970s, as well as the possible disincentive and other adverse effects that the system might be having, were attracting attention, and most notably the much cited Kay and King (1978). However, a recent two-volume study of the British tax system to 1979 found that politicians had consistently placed their perceptions of equity (or just taxes) above considerations of efficiency, with economists often consulted but rarely decisive (Daunton 2002). There 22 Meade was also very active in tax reform, culminating in his chairing IFS (1978), and had long been concerned that the high levels of personal taxation on grounds of redistribution were adversely impacting on incentives (Meade 1948).

Indeed, were it not so there could not be the Postan, Hutchison and Johnson critiques which helped fuel the fires for the eventual more direct challenges upon the Keynesian economics establishment in the 1970s. In earlier studies, we have raised objections to the representation of British mainstream economics contained within those critiques. Here we reiterate that there has been too much focus on stylised conflicts in macroeconomics. As Kearl et al. (1979, p. 36) observed from their study of professional opinion amongst US economists: 23 See Ellison (1994) and Thompson (1996) for those economists who were directly involved in Labour Party policy formulation. These studies, as with much else of this literature, is concerned primarily with the development of social democratic economic thought rather than with the history of economic thought. There is no comparable volume for the Conservative Party, but see Barnes and Cockett (1994) on policy formulation mechanisms and Cockett (1994) on the allimportant IEA. Notable economists advising leading Conservatives during the 1950s and 1960s included such LSE figures as Paish, Plant, Robbins [check also Jewkes, Dennison, Bauer, Yamey***; a St Andrews connection***] There is one notable example of where a – presumed to be politically neutral – (Cambridge) economist was used by the Conservative government in the early-mid 1950s to investigate contemporary concerns about the burgeoning cost of the National Health Service; the report, which found no substantive evidence of ill-administration or poor cost control, was a profound disappointment to the government (Bridgen and Lowe 1998, p. 49). Economists, growth and welfare in the Keynesian era [2nd revise;08/02/2005 08:18] page 27/32 ___________________________________________________________________________________ Consensus tends to center on micro-economic issues involving the price mechanism while the major areas of disagreement involve macro-economic and normative issues. The normative nature of many issues also allows ideological considerations to become important. However, it is clear from this analysis that the perceptions of widespread disagreement are simply wrong. On the other hand, it is true that for many outside the profession the questions of greatest interest are also those that generate the most disagreement within the profession. Hence a good deal of the sampling of economists’ advice, which is in turn communicated to the public, comes from the weakest cell in our analysis – macro-economic policy. 6.2 This conclusion is equally applicable to the British profession, and it is been one of the purposes of this paper to revive a somewhat forgotten and much under-utilised source to show that British economists when sampled in like manner appeared similarly consensual and orthodox on microeconomics. Such a conclusion obviously sits uneasily with the now deeply embedded IEA version of the British economics profession, and of its policy advice during the Keynesian era, as irredeemably dirigiste and antipathetic to an efficient and robust free market economy. That story in any case overstates the influence of the economists, it gives far too much attention to public pronouncements as against the private actions of those few economists who were close to the centre of policy formulation; and it also ignores the fact that throughout the 1950s and 1960s there were economists, notably but not exclusively associated with the LSE, who subscribed to the Paish critique and accordingly campaigned for governments to increase the maximum level of unemployment it would tolerate so that demand management could escape the confines of Stop-Go. 6.3 And what about the representative agents and the ill effects of their pseudoKeynesianism? Postan, Hutchison, Johnson and the rest would not have been able to sustain their version of events had they known what we now know about the conduct of those few economists who mattered inside the Labour administrations of the 1960s: they spent their time, in so far as their time-budgets were actually allocated to economic advice as against routine administration, not in stoking up the inflationary fires and encouraging the politicians to ever more dirigiste interventions but in the very opposite. Cairncross’s moderation would not have surprised, nor perhaps MacDougall’s, but Kaldor and Neild also appear from the official records now available to have been significant voices for moderation and reason. Only Balogh came close to the caricatures, and his influence was always less than he or his enemies imagined.
