The existing techniques are found to suffer from theoretical problems due to the lack of any formal theory of risk in corporation finance. To remedy the deficiency, the paper develops a new theory of risk based on the anticipated return, the operating risk index, the financial risk index, and the expected project life. Hence, an investment project is a four dimensional vector. The paper stipulates that a financial manager’s preference relation on a set of investment projects is a weak order. Imposing the behavioral risk postulates such as the presence of the most preferred and least preferred project, the sure thing principle, and the generalized Markowitz criteria, the paper asserts and proves that there is a continuous utility function which relates the four return and risk attributes of an investment project to its cash equivalent or coefficient: a cash equivalent or coefficient function. The paper then illustrates how to measure a cash equivalent function or its coefficient function from an experiment. It is based on presenting a hypothetical project at 10 prices to a subject who must either accept or reject the purchase of the project at each of the 10 prices. 160 dichotomous responses are elicited by repeating this experiment at 10 hypothetical prices and 16 different experimental settings, By means of logistic regression, it is possible to estimate the probability of acceptance and that of rejection at the 16 experimental settings from which 16 cash equivalents or coefficients are estimated. The cash equivalent function or its coefficient function are estimated by fitting response surfaces over the 16 experimental settings to the 16 estimated cash equivalents and coefficients. Finally, a lease or buy decision analysis is conducted where the cash equivalent method of capital budgeting analysis is applied. The paper should be of great interest not only to financial economists but also to behavioral decision theorists and operations researchers, who work in the areas where the measurement of a cash equivalent or its coefficient plays a key role. 2 A Theory and Measurement of Cash Equivalents for Lease or Buy Decisions 1. Introduction A lease analysis used to be one of major subjects in financial management in 60s and 70s. However, its importance appears to have greatly declined in the recent past. The topic appears to be no longer regarded as theoretically stimulating to many researchers in corporation finance. This can be reflected in the following statements: “a lease or buy decision is a straight forward application of theories developed elsewhere…”. ……… “… the scant empirical literature on leasing is reviewed.”1 In spite of the fact that leasing may have been viewed no longer a frontline issue in corporate finance, truth is that there are many issues left uninvestigated in lease or buy decisions.2 The most critical issue which has been the main source of problem is the lack of a theory of risk applicable to investment decision in corporation finance. The purpose of this paper is to present a new theory of risk and address unsolved issues in lease or buy decisions by means of the new theory. 1 The two quotations are found in Chapter 17 of Copeland, Weston, and Shastri 2005. 2 It must be pointed that the lack of their interest does not necessarily imply that lease or buy decisions are a topic actually exhaustively studied. Academic researchers are at times akin in behavior to slash and burn farmers. The latter are constantly on the lookout for new plots with full of nutrients. However, they tend to desert their plots at the first sign that goings have become tough. 3 The organization of this work is as follows. Section 2 provides the major reasons why this work is worthy of investigation. Section 3 describes a theory of cash equivalents, which establishes an axiomatic foundation for cash equivalents. Section 4 discusses how to measure cash equivalents or its cash equivalent coefficient by means of a lease or buy case. Section 5 shows how a lease or buy analysis should be conducted by means of the cash equivalent method of capital budgeting. Section 6 summarize what is accomplished in this work and presents concluding remarks highlighting its key findings. 2. Motivation Vancil 1963 appears to be one of the earliest researchers in accounting that investigated lease or buy decisions. Other works published in accounting journals include Bower, Herringer, Williamson 1966, Beechy 1969 and 1970. Mitchell 1970. Wyman 1973. A complicating feature of lease or buy decisions arises due to the fact that incremental cash flows in lease or buy decisions not only consist of changes in operating cash flows such as after tax rents, lost deprecation tax savings, the lost salvage value of an asset to be acquired but also those in financial cash flows such as loan repayment and tax savings on interests. The purposes of Vancil’s as well as of other accountants’ works are to identify appropriate incremental cash flows and formulate lease or buy decisions as capital budgeting problems. Researchers in finance also found these works to be of their interest as well. They proposed a number of different approaches to lease or buy decisions. Such lease or buy studies pertinent to this works include Johnson and Lewellen 1972, Roenfeld and Osteryoung 1973, Bower 1973, and Myers, Dill, and Bautista 1976.3 3 For additional works on financial leases, see Doenges 1971, Gordon 1974. Keller and Petersen 1974. Henderson 1976. Lewellen, Long, and McConnell 1976. 4 Earlier works on lease or buy decisions discounted lease rentals at the before tax cost of debt and lost depreciation tax savings, tax savings on lease rentals to be paid, and lost interest tax savings at the after tax cost of debt in order to arrive at the net advantage of leasing(henceforth denoted by NAL). Bower 1973 was credited with establishing the practice of discounting the aforementioned incremental cash flows at the after tax cost of debt. In establishing their result, Bower 1973 made use of an economic assumption later referred to as the equivalent loan equation. Whereas, Myers, Bautista, and Dills 1976 employed the binding constraint on debt capacity and established the use of the after tax cost of debt in lease or buy decisions similar to that of Bower’s approach. An interesting development in the analysis of lease or buy decisions is the emergence of the modified risk adjusted discount rate method (henceforth referred to as the MRADR method) under which that the proponents of this approach have insisted decomposing the components of incremental cash flows into its component cash flows and discounting riskier operating cash flows, for instance, such as the lost salvage value of an asset under the lease option at the weighted average cost of capital and discounting less risky cash flows, for instance, such as tax savings on interest at the after tax cost of debt. Disputes arose as to which incremental cash flows should be discounted by the after tax cost of debt and which ones by the weighted average cost of capital.4,5 To bypass the disputes, some researchers such Miller and Upton 1976. Frank and Hodges 1978. Levy and Sarnat 1979. 1984. Gutman and Yagel 1994. Steele 4 For instance, see the survey by Bower 1973, Schall 1973, Johnson and Lewellin 1973, Clark, Jantorni, and Gann 1973, Lev and Orgler 1973. 5 It is necessary to realize that the tax rate gives rise to uncertainty because it depends on the level of a firm’s profit. For this reason, the after tax operating cash flows in lease or buy decisions such as depreciation charges, 5 as Roenfeld and Osteryoung 1973 resorted to the cash equivalent approach in lease or buy decisions. Whereas, some others such as Beechy’s 1969 and 1970. Mitchell 1970, as well as Doenges 1971 adopted the internal rate of return method (henceforth abbreviated as the IRR method) and thus bypassed the use of the MRADR method.6 However, Schall 1974 was vocal in rejecting Beechy’s IRR method based on the ground that the risk of a project is not fully taken into account in computing the net advantage of leasing. The correct procedure is the net present value method which maximizes shareholders’ wealth using the multiple discount rates under the MRARD method according to his theory. The point of interest in Schall’s 1974 paper is that the additivity of a utility function was alluded as perhaps one of the critical assumptions to rationalize the validity of the MRADR method in lease or buy decisions. The MRADR method appears to be originally attributed to Modigliani and Miller (henceforth abbreviated as MM) in their papers 1958 and 1963. Myers 1974 discussed a similar method of using multple discount rates commensurate with the risks of cash flows involved in discounting. He referred to his method as the Adjusted Present Value method of capital budgeting where after tax operating cash flows are discounted by the weighted average cost of capital and tax savings on interest are discounted by the before cost of debt on the belief that the latter are more certain. The procedures of lease or buy analyses due to Bower 1973 lease payments, changes in operating expenses and so forth are also exposed to a firm’s business risk at large. 6 Roenfeldt and Osteryoung 1973 used the after-tax cost of leasing which is compared against the after tax cost of debt. The former is derived as an internal rate of return. Hence, their method is similar to that of Beechy. However, they are keenly conscious aware of risk differentials among cash flows when they applies a certainty equivalent coefficient to the cash flow from the salvage value of an asset bought. Mitchell 1970 and Doenges 1971 also derive the after tax cost of leasing which is compared with the after tax cost of debt. 6 and Myers, Bautista, and Dills 1976 are highly popular in finance literature but they rest on the assumptions such as the loan equivalent equation and the binding constraint on the capital structure. However, Johnson and Lewellen 1972 pointed out that that tax savings on interest are not part of returns to investment (i.e., operating cash flows) to be discounted in arriving at the NAL. They maintained that interest tax savings should reflected in the after tax cost of debt. Hence, discounting interest tax savings at the after tax cost of debt and additing the latter to the present value of operating cash flows is a double counting. To quote from their work, “the more basic error is including in the cash flow analysis any form of interest charge or interest tax shield to begin with,” In essence, they implied that MM’s theory is erroneous. Johnson and Lewellen 1972 and Schall 1973 neither utilized the debt equivalent equation nor the binding debt capacity constraint. However, the problem with their approach to lease or buy decisions is the use of the MRADR method. In what follows, the problem of the MRADR method will be carefully reexamined to show that the addivitity assumption is bound to fail in reality. Hence, so does the MRADR method. Let a two tuple (x,y) respectively represent a firm’s perpetual stream of tax savings on interest and that of the after tax operating income y and u(x,y) the utility function which represents the value of the cash flow streams to the firm. Let i be the interest rate on debt and r the rate applicable to the after tax operating income y. Under the MRADR method, the value of the two streams x and y is viewed as the sum of the value v of the tax savings on interest x and the value w of the after-tax operating income y as follows: u(x,y)=v(x)+w(y) where 7 v(x)= x i and w(y)= y 7 . r The purpose of this discussion here is to demonstrate by means of a counter example that the additivity principle could readily fail. Modigliani and Miller Paradox Suppose that John Michaels, an MBA student in an accounting course, participated in an experiment where a subject is presented with the following four pairs of perpetual streams of interest tax savings and after-tax operating earnings in dollars: ($100,$50), ($10,$50), ($100,$500), and ($10,$500). In the first experimental session, John prefers ($10,$50) to ($100,$50), since John finds the level of interest implicit in the interest tax savings of $100 is too high in relation to the after-tax operating earnings of $50 in the sense that the firm might become insolvent, provided that the tax rate is, for instance, a marginal corporate tax rate, for instance, 50%. However, in the second session, John prefers ($100,$500) to ($10,$500) because the level of the after tax operating cash flow of $500 should be able to cover the interest expenses implicit in the tax savings of $100: no insolvency risk. John’s preference order should imply the following inequalities in utilities: u(10,50)=v(10)+w(50) > u(100,50)=v(100)+w(50) and 7 Recall that MM utilized this method to evaluate the value of their levered firm in their 1958 and 1963. Hence, this is the well established practice in corporation finance. 8 u(100,500)=v(100)+w(500) > v(10)+v(500)=u(10,500). From the first inequality, v(10) > v(100) 100 10 i i which implies that i must be negative. Whereas, his second response implies the inequality below. v(100) > v(10) which means that i is positive. 10 100 i i Contradiction!. It is pointed out that the additivity of a utility function cannot hold because the value of tax savings on interest is dependent on the level of the after tax operating cash flow stream. The latter is equivalent to a violation of the independence axiom in the language of utility theories.8 The modified version of the MM theory of capital costs insists that the MM theory is valid when the debt ratio is moderate. However, the implication of this counter example is that the MM theory fails when the level of operating cash flow is not sufficiently high to cover the interest expenses, even when the debt ratio is moderate. What matters is not a firm’s debt ratio but the level of operating earnings in relation to interest expenses. Thus, the MRADR method is a theoretically invalid method in general. This implies that a lease or buy analysis based on the MRADR method is invalid. Now, the cash equivalent method of capital budgeting utilized by Roenfeld and Osteryoung 1973 is one method which has not been so far unscathed in this survey of lease or buy analysis. 8 Indeed, should MM be given this choice, they would have preferred (100,500) to (10,500). That is, they should maintain that the tax savings of 100 on interest will be preferred to the tax savings of 10 on interest because they stipulate that the firm under consideration belongs to a risk equivalent class: no change in financial risk. 9 However, it is necessary to reformulate the cash equivalent method so that it can be free of the additivity principle and can be applied to lease or buy decisions without invoking the MRARD method. For this reason, it becomes necessary to construct a new theory of risk from which the cash equivalent method applicable to lease or buy decisions can be rigorously derived as a formal risk theory. 3. A New Theory of Risk The approach to find an alternative solution to lease or buy decisions is inspired by the cash equivalent method of capital budgeting.9 The key focus of this paper is to present the cash equivalent method, whose axiomatic basis has not been carefully investigated in corporation finance.10 Hence, what will be discussed in this section is a foundation on which a new cash equivalent method of capital budgeting will be constructed.11 The reminder of this section present basic terms and definitions at the beginning and then state the main assertions of the theory with the proofs. §3.1: Projects An investment project can be represented as a point on the four dimensional Euclidean space. A decision maker (henceforth denoted as DM) is to examine the return and risk attributes of a project. Let a four tuple P=(,,,) represent a project.12 The first 9 See Chapter 11 of Financial Management by Keown, Martin, Petty, and Scott, Jr 2005 for the certainty equivalent approach to capital budgeting. In this work, the cash equivalent method and the certainty equivalent method are the same. 10 No axiomatic theories of risk are available in corporation finance except the expected utility theory and its variants. 11 See Luce and Suppes 1957, Rabin 1998, and Starmer 2001 onto be discussed in this section are based. 12 Under the expected utility theory, the distribution of the return to investment has been an object of choice. However, the new theory is deliberate in choosing the four risk return attribute as an object of choice in this work. It is in light of the fact that business decisions are typically made without the assessment of any probability distribution involved. Hence is the 10 attribute is the anticipated level of return to a project. The second risk attribute is the business or operating risk index which results from accepting the project at t=0. The third attribute is the financial risk index at t=0. Let the fourth parameter represent the life of a project. All projects (,,,)s of interest in this work are by assumption contained in a closed and bounded 4 dimensional Euclidean space S specified as follows: Definition 1(The Domain Space): The domain space S is a set of projects contained in a closed and bounded four parameter Euclidean Space S such that S={(,,,),*≤≤, *≤≤, *≤≤, *≤≤} where a superscript star * is the maximum value to be taken by each variable and a subscript * is the minimum value of each variable. A new theory of risk is concerned with assessing the cash equivalent c of a risky project PS. To introduce this term precisely, it is necessary to utilize the sure project PS. The following definition is in order: Definition 2(The Sure Project C): C=(c,0,0,0) project P and is referred to as the sure project PS if a DM finds a C=(c,0,0,0) as good.13 The definition of the cash equivalent c of a project P can be formulated as follows. Definition 3(Cash Equivalent c): The cash equivalent of PS is the first element c of its sure project C=(c,0,0,0) representing a certain amount of cash. anticipated return from a project rather than the expected return which cannot be obtained without the knowledge of the probability distribution. 13 A cash equivalent seems to have originated in connection with the St. Petersburg game whose cash equivalent is log 2. See Levy 1998. 11 It is necessary to point out that the cash equivalent c of a project PS does not always exist unless a DM’s risk preference conforms a certain type of restrictions. Hence, the next task is to describe a set of such axioms or postulates which guarantee the existence of the cash equivalent c of a project P. A DM in this work is often a team of individuals in charge of corporation finance. It is stipulated that the team acts according to the risk return preference of the corporation for which they work. Hence, the cash equivalent c for any PS will be this firm’s or this team’s cash equivalent c. §3.2.1: Generic Axioms Let Pa and Pb are two projects in S. That Pa is preferred to Pb is written as {Pa>*Pb }. That Pb is preferred to Pa does not hold is written as not{Pb>*Pa}. That Pa is as good as Pb is represented by {Pa*Pb}, which is referred to as an indifference relation. Let an arrow indicate direction of implication. Let A and B signify two statements. That A implies B will be thus denoted by A B. The converse of the latter is written as A B. When both hold, A is equivalent to B and written as A B. (Pa>*Pb or PaPb} is written as {Pa*Pb}. This relation is the preference-indifference relation. The latter can be defined as the negation of a preference: {Pa*Pb}=not{Pb >*Pa}. The preference relation can be defined as the negation of the preference-indifference relation as follows: {Pa>*Pb}=not{Pb*Pa}. The indifference relation can be defined from the preferenceindifference relations as follows: {Pa*Pb and Pb*Pa}{Pa*Pb}. It is seen that one relation can be defined by other relations. 12 Let us briefly discuss these properties of these relations. 1. Preference Relation>*: A preference relation >* is said to be asymmetric: {Pa>*Pb}not{Pb>*Pa} for any Pa and PbS, irreflexive: not{Pa>*Pa} for any PaS and transitive: {Pa>*Pb} and {Pb>*Pc} {Pa>*Pb} for any Pa, Pb and PcS. 2. Indifference Relation ~*: The indifference ~* is said to be symmetric: {Pa~*Pb} {Pb~* Pa} for any Pa and PbS, reflexive: {Pa~*Pa} for any Pa in the set S and transitive: {Pa~*Pb} and {Pb~*Pc}{Pa~*Pc} for any Pa, Pb 3. Connectedness and PcS. Pa Pb Pc Given every pair of prospects P a and P b S, preference relations are said to be connected: 1){Pa>*Pb }, 2) {Pa<* Pb} or 3){Pa*Pb} 4. Mixture Transitivity: It is necessary to define the notations involving both preference and indifference relations as follows: {Pa<*Pb or Pa~*Pc} {Pa<*Pc} or {Pa~Pb or Pa<*Pc} {Pa<*Pc}. 5. Preference-Indifference *: The preference-indifference relation is said to be symmetric: {Pa*Pb}{Pb*Pa} for Pa and Pb S, reflexive: {Pa*Pa} for any PaS. It is transitive: {Pa *Pb and Pb*Pc}{Pa*Pc}. So, a stage is set for presenting five behavioral postulates that are regarded as sufficient conditions. §3.2.2: Behavioral Postulates Definition 4(The Sure Thing Postulate): 13 For a sufficiently small cash , there exists the least preferred sure project such that C*=(,0,0,0)*P for any project PS. For some large *, there exits the most preferred sure project such that P*(*,0,0,0). Let the sure project C*=(*,0,0,0)S be the most preferred project and included in set S. However, the least preferred project (*,0,0,0) is not included in set S. Hence, the domain space S of prospects is also a bounded and closed set in preference orders in the following sense: {C**P*C*|PS}. The next four postulates are referred to as the generalized Markowitz axioms, since they are in essence a 4 dimensional version of the Markowitz criteria. Definition 5(The Profit Maximization Postulate): {(,,,)>*{(',',',')}{(<’)} Definition 6(The Operating Risk Minimization Postulate): {(,,,)>*{(',',',')}{(>’)} Definition 7(The Financial Risk Minimization Postulate): {(,,,)>*{(',',',')}{(>’)} Definition 8(The Project Life Postulate): {(,,,)>*{(',',',')}{(>’)} Several comments are in order. In corporation finance, two types of risk have been recognized: operating risk and financial risk. Further, business investments are by nature intertemporal decisions and 14 hence it is necessary to take into account the time value of money. The latter implies that the risk associated with a project rises as the life of a project becomes longer due to the fact that individuals are impatient to utilize money for immediate consumption as well as due to the fact that the degree of uncertainty rises as the time to receive the anticipated income is delayed as the project’s life becomes longer. §3.3 The Theory of Cash Equivalents The first assertion to be proved is the lemma which states an important property of preference relations under the generalized Markowitz criteria. The property will be needed in establishing the continuity of the cash equivalent function. Lemma 3(The Strictly Increasing Preference Structure): For any ' and such that 0'<1, a more preferred project P=(p,p,p,p), and a less preferred project Q=(q,q,q,q) in set S, 'P+(1-')Q*<*P+(1-)Q* where p>q,p<q.p<q,p<q. Proof of lemma 1: The proof can be established by comparing each component of P+(1-)Q* with that of ’P+(1-’)Q*. In light of p>q, p+(1-)q=q+(p-q)>'p+(1-')q=q+’(p-q) whereas, p+(1-)q=q+(p-q)>'p+(1-')q=q+’(p-q) in light of p<q. A similar inequality should hold for the remaining two risk parameters, and . Thus, The Inequality of the assertion must hold. On any line emanating from the less preferred project toward a more preferred project, the degree of preference will be strictly 15 increasing as a point on this line moves away from the less preferred toward the more preferred. The main theorem will be stated and its proof will be provided by means of the two lemmas in this subsection Theorem 1(The Representation Theorem): There exists a cash equivalent function u which maps projects P and P’S to its cash equivalents c and c’ R[,*] such that u(P)=cu(P’)=c’P*P’ provided that the generic axioms 1, 2, 3, 4, and 5 of §3.2.1 on the preference orders and the behavioral postulates 1, 2, 3, 4, 5 of §3.2.2 hold. The theorem directly follows from the two lemmas to be proved next. The first task is to define the Euclidean norm which will be needed in the process of establishing the lemmas. Definition 9(The Euclidean Norm): Given projects P=(,,,) and P’=(’,’,’,’), the Euclidean norm |PP’| is the distance between the two projects defined by the following: |P-Q|= (aa')2 ( ') ( ') ( ')2 . 2 2 In what follows: the proof of the lemma 2 will be presented in its entirety. Whereas, that of the lemma 3 will not be depicted in detail because the latter is similar to that of the lemma 2. Lemma 2(The One to One Property): For any PoS, there is a sure project (co,0,0,0),for co R=[, *], such that (co,0,0,0)*Po provided that the same condition of the main theorem holds. Proof of lemma 2 by the Bisection Search Algorithm Search Step 0: 16 Let C*=(,0,0,0) and C*=(*,0,0,0) are respectively the most preferred project located at the North and the least preferred project at the South of the sure thing postulate. The search area is this straight line C={C*+(1-)C* for any , 01}. Set the starting search vector to the following: H(0)=C*. {H(0)*Po} must hold for all Pos , since H(0) is the least preferred sure project located down at the South. This is the end of the search step 0. Continue to the next search step. Search Step 1: It is necessary to formulate a new search vector H(1). To this end, let D(0) denote the difference C*-C* as follow: D(0)=(*-,0,0,0). The Euclidean norm of the vector D(0) is the following: D(0) =*- The next search vector H(1) will be the mid point of the line C as follows: H(1)=H(0)+(0) D(0) 2 where (0)=+1 because H(0) must be pushed up to the North or to the direction of C* on the line C. Notice that H(1) is a sure project (c1,0,0,0) where c1 (0) * . 2 Suppose H(1)*Po. Discard all sure projects C=(,0,0,0)s out of C such that C<*H(1). Let C redenote the remaining projects. Suppose 17 {Po*H(1)}. Again discard all Ps such that P>*H(1). Let C redenote the remaining sure projects. To form the nest search vector H(2), let D(1) be the difference from H(1) to C* or from H(1) to C* as follows: D(1)= D(0) . 2 Define the new search vector H(2) on the line C whose length |D(1)| is one half of the original length |D(0)| as follows: H(2)=H(1)+(1) D(1) 2 where (1) is either +1 or -1 respectively depending on whether {H(1)* Po} or {PoH(1)} holds or whether or not H(1) must be pushed up to the direction of the North or pushed down to the direction of the South. The search area will be reduced to one half again every time since one half of the sure projects Cs that are found no longer needed will be discarded. The new search vector H(2) is a sure prospect (c2,0,0,0) where c 2 c1 (1) * 2 2 . Continue the search to the next search step 3. The process similar to what is seen at the previous search step 2 must be repeated. …… Suppose that the search vectors H(0), H(1), H(2),…, H(t-1) have been generated. Continue the search to the search step t. Search Step t: Let the new search vector H(t)=(ct,0,0,0) be defined as follows: H(t)=H(t-1)+(t-1) D(t - 1) 2 18 where (t-1) is either +1 or -1 respectively depending upon whether or not H(t-1) has to be pushed up to the direction of the North or pushed down to the direction of the South that are left, D(t-1)= D(0) 2 t1 and t1 (t 1) t * 2 t1 . The search process should continue ad infinitum. It is necessary to show that the bisection algorithm is convergent. To prove this, consider the Euclidean norm H(t s) H(t) below: H(t s) H(t) c ts c t . Then, the following inequality holds: H(t s) H(t) H(t s) H(t s 1) H(t s 1) H(t s 2) ... + H(t + 2) - H(t + 1) H(t 1) H(t) . Then, H(t s) H(t) (t s 1) D(0) 2 t +s (t s 2) D(0) 2 (t + 1) D(0) 2 t 2 t +s .... (t) D(0) 2 t 1 . Since d(t) 1 for any t, H(t s) H(t) * 2 t 1 1 1 1 s s1 ... 2 1. 2 2 2 2 Summing up the content of the brace, 19 H(t s) H(t) * 2 t * 1 1 s t . 2 2 For any finite s and an arbitrarily small , >0, there is an arbitrarily large natural n such that * 2 t < for any t> n. It is seen that H(t) is a Cauchy sequence that is convergent. In words, H(t) will become as good as the prospect Po and u(H(t))=ct converges to u(Po)=co as t passes to infinity for any Po S. Lemma 3(The Onto Property): For any coR=[, *], there is a project PoS such that (co,0,0,0)*Po provided that the conditions of the representation theorem holds. Proof of lemma 3 The bisection algorithm similar to the previous one will be utilized to locate a project Po such that Po is as good as (co,0,0,0). The line on which this search must be carried out will be the line {P()=P*+(1-)P*,0l1}. The length of the line is D(0)=|P*-P*| Using a similar bisection algorithm on this line, it is readily possible to locate the project Po such that Po is as good as (co,0,0,0). §3.4 The Continuity of a Cash Equivalent The continuity of a cash equivalent as a function of the four parameters is important. With this property, the latter can be approximated, for instance, as a lower order polynomial function of the four parameters. This property will enable us to significantly simply the task of assessing a cash equivalent function by conducting a 20 behavioral experiment where cash equivalents to stimulus projects are elicited from subjects. Definition 10(The Continuity of a Real Valued Function): A real valued function mapping a project Po in the interior of the set S to its cash equivalent co into the open interval (c*,c*) to be a continuous function at the project Po, is said provided that, for any arbitrarily small real >0, there exists another small real such that |P-Po|< and for any such P in the above 4 dimensional sphere of radius , the following inequality must hold: u(P) u(P o) < . Now that the continuity of a function on the set S is formally defined, a stage is set for proving the continuity of the cash equivalent function. Theorem 2(The Continuity Property): The cash equivalent function u mapping a project P in the interior of the set S into the open interval (,*) is a continuous function of the return and risk attributes, , , , and . Proof: Consider any project Po in the interior of the set S with u(Po)=co. Let be a small real >0. Let the projects P(+) and P(-) denote the most preferred and least preferred corner project of the 4 dimensional cube with the half length of and centered at the project Po as follows: P(+)=(o+,-,-,-) and 21 P(-)=(o-,+,+,+). The line P={P(+)+(1-)P(-),01} represents the line of strictly increasing preference of the lemma 1. Set to 1/2, P1/2 is Po. P1 is P(+) and P0 is P(-). Hence, for a small , >0, u{P(-)}<co-<u(Po)<co+<u{P(+)}. Let ’ and ” be another small real constants such that 0<’<1 and 0<”<1. Let P(’) denote the project located on the straight line connecting P(+) and Po such that u{P(’)}=u{(o+’,-’,-’,-’)}=co+. Let P(”) be another project located on the straight line connecting P(-) and Po such that u{P(’)}=u{(o-’,+’,+‘,+‘)}=co-. The two projects P(’) and P(”)can be readily located by the bisection algorithm of the lemma 3. Let be the smaller of the ’ and ”. Let P(+) and P(-) be defined as follows: P(+)=(o+,-,-,-) and P(-)=(o-,+,+,+). The two projects above are the most preferred and least preferred corner points of the 4 dimensional closed cube which in turn contained in the 4 dimensional closed box defined by P(’) and P(”). The former cube whose half side length is always contains the sphere of radius . Let P be any project contained in this 4 dimensional sphere with radius . Then, co-<u(P)<co+ 22 which is the following: |u(P)-u(Po)|<. The continuity of the cash equivalent function u is established. Further, due to the lemma 1, the discountinuity of the second kind is ruled out. It is useful to expand on this point. The cash equivalent surface covering the set S is strictly increasing as a project moves away to any direction from the least preferred corner project of the set S. For any intermediate point c(,*), there is a project P by the lemma 3 such that u(P)=c. Hence, there is no gap on the cash equivalent surface suspended over the set S. That is, the surface is continuous over the set S. Several remarks are in order. The theory of cash equivalents is flexible because the return and risk attributes can be increased to more than four parameters, provided that the Markowitz postulate holds for a new paramter. In corporation finance, business risk is often mentioned on conjunction with operating risk. It can be readily incorporated into this theory by increasing the number of parameters to five and adjust the generalized Markowtiz postulates as follows: “the greater the business risk index, the less preferred the project, holding the other parameters constant.” The second remark is with regard to the cash equivalent coefficient associated with a cash equivalent. It is utilized with the risk free rate of interest if. Let the cash equivalent coefficient, , be formally defined in the context of this work as follows: Definition 11(The Cash Equivalent Coefficient): The cash equivalent coefficient n is a constant applied to , the anticipated return in year which is related to the cash equivalent c as follows: 23 c= , 1 i f or it can be defined as follows: = c 1 if . Once the cash equivalent of a project is obtained, it is readily possible to derive the cash equivalent coefficient. Since a cash equivalent is a continuous function of , , , and , the cash equivalent coefficient associated with it is also a continuous function of the latter. 4. Measurement of Cash Equivalents The section will illustrate how cash equivalents and its coefficients should be estimated in an experiment. The experiment is carried out by means of the following lease or buy decision case. Paradise Enterprise Case: Paradise Enterprise, Inc. is a chain of beach side bars and restaurants in the Virgin Islands. Joe Dolittle, President, wants to purchase a gaming terminal for $20,000 from Eden Technology. The bank is willing to loan him $16,000 at 8%. The term of the loan is 4 years, the expected life of the gaming machine. The terminal will be depreciated under MARCS with the weights of 33%, 45%, 15% and 7% respectively in the next four year. Paradise must get a maintenance contract for $80 a year. The salvage value will be $800. Suppose that Paradise leases it from Eden Tech. The rental will be $6,500 per year. At the end of the expected life, the terminal must be returned to Eden. The firm’s marginal tax rate is 40%. To study whether or not the project is a worthy venture, a team of four recent MBA graduates from top universities with major in finance 24 has been at work at Paradise. They have participated in all capital budgeting analyses conducted by the firm for a year. They are not full informed of the firm’s risk preference over projects routinely considered by the firm. They are now ready to advise Joe as to how the cash equivalent method of capital budgeting should be conducted to solve the lease or buy decision problem at Paradise. They have already conducted the traditional analysis of lease or buy decisions. It indicates that a gaming terminal is a worthy investment. The next step is to analyze whether or not it should be leased or purchased by the loan. To conduct a lease or buy analysis, Joe wants to estimate the cash equivalent coefficient function from cash equivalents elicited from the four MBA graduates as experimental subjects. It is necessary to conduct an experiment to obtained cash equivalents c from the subjects and then estimate the coefficient function 4 for the firm. Recall that the project must be represented by the four tuple, (, , , ).. Let the anticipated return be the net terminal value of a project where it is the future value of incremental cash flows less the future value of an outlay. The use of the net terminal value is inspired by the modified internal rate of return. It enables us to dispense the additivity principle and bypass the problem discussed in connection with the MRADR method. It is necessary to specify the operating risk and financial risk indices and , which will be proxied by the following two indices. = max F (1 v)S and 25 I = max I (1 v)S where v is the variable cost per $1 in sales, F is the fixed cost, I the interest, and S, the average sales, provided that the gaming terminal is adopted. The former of the two proxies is the ratio of the operating break even sales coverage divided by the sales level. The latter is that of the interest sales coverage divided by the sales level. The closer the ratios to 1, the higher the operating risk or the financial risk. See Matsumoto and Hoban, 2001 for an exposition of the breakeven sales coverages. To determine these indices, the analyst team must prepare the pro forma income statement and balance sheet under the assumption that a project at issue is adopted. The four MBAs are asked by Joe to become experimental subjects and provide cash equivalents with hypothetical projects presented to them as stimuli. Joe wants to use 16 stimulus projects to elicit cash equivalents because there are four factors and at least two levels per factor must be utilized. Hence, a 24 factorial design ia utilized. Insert table 1 approximately here Observe table 1 which lists the four parameter values for four projects i=1, 2, 15, 16 and responses yij, j=1,2,…,10. The factor i is set to $1,000 and $2,000 in the experiment. The operating risk index i is set equal to 0.0 and 0.3. The financial risk index is set equal to 0.1 and 0.2. The expected life i are set to 3 and 5. The total number of experiment settlings is thus 24=16. The four subjects was randomly divided to a team of two. The randomly chosen 8 projects are assigned to the first team. The remaining 8 projects are assigned to the second team. Table 1 presents the first two and last two experimental settings for illustration. The first 26 column is for the stimulus project number starting from 1 and going up to 16. The second column shows the replication numbers starting from 1 to 10 each experimental setting. Each team is required to answer whether or not they want to purchase the project (i,i,i,i) at the price cij listed on the third column. Suppose that a team than the price cij. believes that each project is worth more Its response is coded as yij=1, indicating that the purchase offer is accepted by the team at the j-th replication. If not, his response yij is coded 0. If the offer is rejected by the team, the price cij is increased to a higher amount cij+1 at the next replication. There are 10 prices cijs for each project i. The 10 prices at each experimental setting must be properly spaced ranging from a very low price to a very high price so that the team is certain to switch from yes to no at some price. The 10 prices for the first experimental setting are listed on the third 10 rows of table 1. The project 1 presented to a team is ($1,000, 0.1, 0, 3). If the team decides that the price c11 of $929 is more expensive than its true worth. Thus, its response y11 is 0 in the sense that the price is too high. The price c12 is then reduced to $864. This team still considers the price too high. Its response y12 is again 0. When the price is finally reduced to $805, the two find the project ($1,000, 0.1, 0, 3) to be more valuable than the price of $805. So, the response y13 is 1 at the 3rd replication. This price of $805 is the maximum price below which the subject accepts the investment opportunity. Whereas, $864 is its minimum price beyond which the subject will no longer accept it. Table 1 presents the results of the 40 experimental sessions at which the two teams provide their 40 27 dichotomous responses. The remaining 120 responses are not presented in table 1 for brevity. Insert Table 2 approximately In order to estimate the cash equivalents for the 16 experimental sessions, a logistic regression is fitted to the 160 responses. The panel A of Table 2 presents the estimated logistic regression equation whose dependent variable is z as follows: Z=2.253-0.001-5.316-8.284-0.403 All p-values of the estimated coefficients are significant at 5%. The classification table is presented in the panel B of table 2. The fit of the logistic regression is satisfactory in light to the fact that 70% of 160 cases are corrected classified. The panel C of table 2 presents the estimated probabilities that yij equals 1 and that yij equals 0. For illustration, consider the third replication of the subject 1. The probability P that the response y13 equal 1, is obtained from the following: P(y 13=1)= 1 1 exp 2.253 0.001 (1000 ) 5.316 (0.1) 8.284 * 0 0.403 (3) . It will be readily verified that this P is .81914 at the maximum price of $864. Whereas, P(y13=0)=1-P(y13=1) which is .18086 associated at the minimum price of $805 at which the investment opportunity is rejected. Behavioral theorists believe that a subject accepts a project with 0.5 and rejects it with 0.5 if the price is the cash equivalent. Refer to the experimental setting 1 in the panel C of table 2. Let c be the cash equivalent located between 895 and 805. At $805, Pr(y13=1)= 0.8194 whereas at $864, Pr{y13=0)=0.18086 as listed in the first row of the table. Thus, the cash equivalent c1 for the first experimental setting can be interpolated from the following: 28 864 805 .18086 .81914 c1 805 0.5 .81914 . The resulting cash equivalent c1 is $834. The remaining 15 estimated cash equivalents are also interpolated by using a similar procedure as done above. Panel C of Table 2 exhibits the complete list of all maximum prices with their probabilities Pr{yij=1) and the minimum prices with their probabilities Pr{yij=0) calculated from the estimated logistic regression of the Panel A of table 2. Insert Table 3 approximately here Once a cash equivalent ci is estimated, it is also possible to derive the corresponding cash equivalent coefficient n(i). To this end, substitute ci and i at the experimental setting i. Then, the estimated cash equivalent coefficient i at the i-th experimental setting can be derived from definition 11. The following definition is in order: Definition 12(The Cash Equivalent Coefficient): n(i)= ci i (1 if ) n . Suppose that the risk free rate is 3%. Then, substiting a=1000, c=834, if=0.03 into definition 12, (1)= 834 (1.03) 3 1000 which is 0.9113. The 16 estimated cash equivalents ci and the cash equivalent coefficients n(i) are provided on the last two columns of the panel A of Table 3. Regressing the cash equivalent ci on these covariates i, i, i, and i, it is possible to estimate the i-th cash equivalent function over the four covariates. The panel B of table 3 presents the estimated 29 regression coefficients bis, its standard error, the t-statistics, and the p-values. Three coefficients are highly significant and the coefficient of the operating risk index is significant. The R2 is 93.7% and highly significant. Regressing the estimated cash equivalent coefficients n(i) on the four covariates i, i, i, and i listed on the columns 2, 3, 4, and 5 and the cash equivalent coefficients reported in the 7 th column of the Panel A of Table 3, it is also possible to obtained the estimated cash equivalent coefficient function as shown on the Panel C of Table 3. The estimated coefficients bis of the four covariates are all highly significant with the R2 of 90%. Regressing the estimated cash equivalent coefficients n(i) on the same four covariates over the 16 experimental settings in the Panel A of Table 3, the estimated cash equivalent coefficient function is obtained. The panel C of Table 3 presents this result. 5. A Lease or Buy Analysis This section illustrates how a lease or buy analysis should be conducted under the cash equivalent method of capital budgeting. New notations will be presented to formulate the lease or buy analysis. A = asset value at t=0 Lt = lease rental at year t under the lease option Dt = depreciation charge for year t under the purchase option Ot = an increase in operating costs such as maintenance, insurance expenses and the likes when an asset is purchased rather than leased. If no change occurs, the latter should be set to 0. R = proceeds from disposing the asset at the end of the expected life G = gains or losses if the asset is disposed 30 Bt=loan balance at t d A t =loan amortization at year end t St=equity balance at t e A t =equity amortization at year end t Pd=loan payment in any year t e P t =return to shareholders in year t n=expected life=lease term NAP = net advantage of purchasing NTV = terminal value wd = portion of debt we = portion of equity i = cost of debt if= risk free rate ke = internal cost of equity r = the reinvestment rate=(1-tm)iwd+kewe tm = marginal tax rate These notations will be of great value in formulating a lease or buy analysis with clarity. Two tables will be needed to discuss the lease or buy case. Table 4 presents the loan and equity amortization schedules in panels A and B respectively. Insert Table 4 approximately here The loan payment Pd of $4,830.73 is constant whereas the loan d amortization A t and loan balance Bt vary as clearly seen from Panel B. The t-th return to shareholders is the equity amortization A et plus equity cost keSt. The outstanding equity St will also decline as the loan balance Bt becomes smaller as shown in Panel B. However, the debt ratio will remain at 80%, as seen in Panel C. 31 The loan payment less tax savings on interest to lenders plus the t-th return to shareholders will be the total returns to investors on the last column of Panel D. Panel E shows the present value of the total returns, which equal precisely the cost of the asset which is $20,000. Insert Table 5 approximately here Panel A of Table 5 presents the depreciation schedules under MARCS. Whereas, Panel B is the worksheet which systematically computes the net terminal value of the project according to the formula below: Definition 13(The Net Terminal Value): N TV t m D t (1 t m ) L t O t (1r) n n -t (R t m G) - (1 + r) A . n t =1 In connection with the NTV computation, it is pointed out that the weighted average cost of capital of r=6.84% is indeed the discount rate which equates the present value of return to shareholders discounted at this rate r. The following definition is in order: Definition 14(The weighted average cost of capital): P A= n t1 d t m i Bt A t k e S t (1r) e t where r=(1-tm)iwd+kewe. Recall in this regard, Panel E of the table 4 shows that the present value of the returns to investors indeed sums up to the outlay of $20,000. The process of the NTV computation is depicted in the panel B of the table 5. The first column presents the labels to identify incremental cash flows involved. The second column shows before tax figures whereas the 3rd column is for after tax figures. The fourth 32 column exhibits the timing of each cash flow. For instance, the first cash flow of lease rentals are due at the beginning of each year for three years. The entries on the next column presents the future value interest factors. The first interest factor on the top is the future value of an annuity due. The future values of 7 cash flows are computed by multiplying the the after tax figures on the 3rd column by the future value interest factors on the fifth column in the last column of the worksheet. Subtracting the future value of the project outlay , the net terminal value is found to be $1.820.80. The four MBA students are highly proficient in accounting and hence prepared the pro forma income statement and balance sheet under the assumption that the lease or buy option is accepted. They are able to derive the % operating leverage index and financial leverage index , which turns out to be 0.2 and 0.15 respectively. Hence, the project is ($1,820.8,0.2,0.15,4). Substitute ($1,820,0.2,0.15,4) into the covariates of the cash equivalent function 4 of the panel C of the table 3 as follows: 4=1.130+0.0001073(1,820.8)-0.525(0.2)-0.0929(0.15)-0.09(4) which turns out to be 0.7210. The final step of the lease or buy analysis is to evaluate the NAP as follows: Definition 15(the Net Advantage of Purchasing): NAP= n NTV (1if ) n . Substitute 4=0.7210, NTV=1,820.8, n=4, and if=0.03 into the NAP above as follows: NAP= 0.7210 (1820 .8) 1.03 4 33 which turns out to be 1,166.40. The NAP is positive and hence, the purchase option should be accepted. Notice in this regard that the rejection of the lease option can occur when the NTV is negative as well as when is negative. There is a direct relationship between the NTV, the cash equivalent, and the required rate of return RR. The following definition is in order: Definition 15(The Required Rate of Return): c (1RR ) n . Substitute NAP=1166.40, =1,820.80, n=4 into the above. Solve for RR, which turns out to be 11.8%. The implied required rate of return RR is considerably higher than the weighted average cost of capital of 6.84%. The NAP can be also obtained as the cash equivalent of (1,820.8,0.2,0.150,4) directly from the estimated cash equivalent function by substituting the parameters into the regression equation of Panel B of table 3 as follows: NAP=760.062+0.808(1802.80)-791.875(0.2)-1043.13(0.15)-175.062(4) which turns out to be 1216.18. Using the same method utilized earlier, the implied required rate of return RR is 10.6%. In either instance, it is highly interesting to observe that the MBA students have shown that their assessment of risks involved is much greater than that implicit in the weighted average cost of capital r=6.84% which supposedly reflects investors’ perception of risk involved. 6. Summary and Concluding Remarks The paper reviewed past studies of lease or buy decisions and found that there is no satisfactory theory of lease or buy analysis. Many researchers mistakenly view lease or buy decisions to be no longer 34 of any interest because all theoretical problems have been resolved. The paper asserts that the only one approach left unexplored is the cash equivalent method of capital budgeting to lease or buy decisions. However, the cash equivalent method of capital budgeting did not become a popular tool in lease or buy decisions in the past four decades perhaps because cash equivalent coefficients are psychological entities and finance researchers in 70s seemed not to be ready for an experimental assessment of cash equivalents. Advances in behavioral finance seems to have changed the climate significantly. It is hoped that researchers are now ready to embrace it, since the other approaches failed. With this background in mind, the paper presented an axiomatic theory of cash equivalents. However, the axiomatic theory of risk is still new to researchers in corporation finance because the expected utility theory dominated the field of finance and no serious attempt has been made to entertain any alternative approach. The new theory is eclectic and inspired by the theory of consumer choice and advances in behavioral decision theories. The axiomatic risk theory without a technique of measurement is incomplete. For this reason, the paper explored an experimental measurement of cash equivalents for lease or buy decisions. It has shown how Paradise Enterprise Case can be utilized to elicit cash equivalents from the student subjects an how cash equivalents for stimulus projects can be estimated from dichotomous responses by means of the logistic regression and the linear interpolation technique. It has shown that the response surface regression can estimate the cash equivalent function and hence the cash equivalent coefficient function. With the technique of measurement, the cash equivalent method of capital budgeting is no longer a theoretical 35 construct but it can be utilized as an operational method in corporation finance. The contribution of this work is to open a new path toward making the cash equivalent method as an operational tool in capital budgeting. The paper should be of great interest not only to financial economists but also to behavioral decision theorists and operation researchers who work in the areas where the theory and measurement of cash equivalents or its coefficient play a key role.
