have devoteda great factthatvotersare frequentlyverypoor-
deal of thought to problems of
governmentalpolicy and, in particular,to the question of properallocation of resourcesbetweenthe public and
privatesectors.'On the otherhand, little
attention has been given to the actual
or to the type
processofdecision-making
of policy likely to come out of the

process. It is the purpose of this article
to discuss one particularmethodofmaking governmental decisions-majority
voting-and to attempt to derive conclusions about its implications for resourceallocationand governmentpolicy.
It is hoped that the conclusionswill be
more realistic than current doctrine,
whichis based on an essentiallyeconomic
view of what "ought" to happen.
Since it is impossible to talk about
everythingat once, the demonstration
will be confinedto certainfeaturesof the
majority process. A number of other
serious problems raised by the voting
system will be disregarded. The most
importantof these concernsa series of
difficulties
and paradoxes in the voting
process itself.3I will also disregardthe

limitationson the functionalefficiency
of the democraticprocess.
I shall consider the operation of
restricmajorityrule undertwo different
tions: logrolling(i.e., vote-trading)permittedand logrollingnotpermitted,startingwith the latter.Since logrollingis the
norm, discussion of the non-logrolling
case must startwithconsiderationof the
institutionalstructurewhich eliminates
logrolling.The standard referendumon
a simple issue is the best example. The
voter cannot trade his vote on one issue
for votes on others because he and his
acquaintances representtoo small a part
ofthe total electorateforthisto be worth
the effortinvolved. Further,the use of
the secret ballot makes it impossibleto
tell whethervotingpromisesare carried
out. In these circumstancesthe voter
will simply vote in accord with his
preferenceson each individualissue.
The contrary case, logrolling permitted,occurs under two circumstances.
First,it occurswherea rathersmall body
of voters vote openly on each measure;

compare his own marginalbenefitsand
costs, and this requiresno knowledgeof
anyone else's utility.He need only decide whetherthe total bargain is to his
advantage or not.5
Note, however, that, while no roads

contributeto therepairoftheroads leadingto thehousesofthemaximizers.Thus
part of the cost of the road-repair
projects will be paid by persons not
party to the bargain, and, since the
maximizersonlycountthe coststo themselves of theirvotes, the general standard of road maintenanceon the roads on
which theylive should be higherthan if
they had to count also the cost of maintainingthe roads on whichthe Kantians
lived. Under such conditions, where
virtueso conspicuouslyis not paying,it
seems likely that at least some of the
Kantian farmerswould decide to switch
to a minimizingpolicy. For simplicity,
let us assume that all of them do this at
once. Since they would still be in a
minority,their change of policy would
not immediatelybenefitthem,but surely they could find two of the original
maximizerswho would,in returnforvery
good maintenance, desert their former
colleagues. It is again obvious that the
new majority would be susceptible to
similardesertions;a permanentcoalition
of 51 farmersforthe purpose of exploiting the remaining49 could thus not be
maintained. In terms of game theory
any combinationof 51 voters dominates
any other size of combination,but no
combinationof 51 dominates all other
575
combinationsof 51.6
The outcome is clear. Each farmer
would enter into bilateral agreements
with enough farmerson other roads to
insure that his own was repaired. He
would then be forced to count as part
of the cost of gettinghis road repaired
the cost (to him) of repairingthe roads
of the other 50 farmers.These bilateral
agreements, however, would overlap.
FarmerA (morepreciselythe farmerson
road A) would bargainwith Farmers B,
... , M. Farmer M, on the otherhand,
might make up his majority from
Farmer A and FarmersN, . .. , Z.
Counting the cost to himselfof the
maintenanceof his road in termsof support forotherroad-repairprojects,each
farmerwouldconsideronlythoseprojects
forwhichhe voted. Thus his expenditure
patternwould countthe tax paymentsof
49 votersas a freegift.The naturalresult
would be that each road would be maintained at a level considerablyhigherand
at greaterexpense than is rational from
the standpoint of the farmers living
along it. Each individual behaves rationally,but the outcome is irrational.
This apparentparadox may be explained
as follows: each voter pays enough in
support for repair of other roads to
equalize the benefithe receivesfromthe
repairofhis own road. But his payments
counted under this systeminclude only
part of the road repairjobs undertaken.]
6 In the "Theory of the Reluctant Duelist"
(American Economic Review, XLVI [December,
1956],909-23) Daniel Ellsberg contendsthat game
theoryreally only applies to "reluctant" players.
Our case is a particularlypure example. The voter
must"play thegame" by enteringintobargainswith

There are otherswhich are the result of
bargains to which he is not a party.
Taken as a group, the road-repair
projects for which he votes representa
good bargain for him, but other ad hoc
bargains to repair other roads will also
take place. He will vote against these,
but, as he will be in the minority,he will
have to pay for them. The result is a
sizable loss to him.
Anyfarmerfollowingany othercourse
of action will be even worse off. A
Kantian farmer, for example, would
never have his own road repaired but
would pay heavy taxes for the support
of repairjobs on otherroads. The whole
process will proceed through elaborate
negotiations;the man who is the most
effectivebargainerwill have a considerable advantage, but the general pattern
will be less than optimal for all parties.
This seems a ratherunsatisfactoryresult, and we should consider whether
thereare not ways ofimprovingit. First,
however,I should like to discuss certain
possible objections to my reasoning.8It
may be said that the maximizersare behaving wickedly and that ethical considerationswill prevent the majority of
the population from followingsuch a
course. Ethical systems vary greatly
from culture to culture, and I do not
wish to rule out the possible existence
somewhereof an ethical system which
could bar logrolling, but surely the
American system does not. Under our
system logrolling is normally publicly
characterized as "bad," but no real
stigmaattaches to thosewho practiceit.
The press describes such deals without
any apparent disapproval, and, in fact,

all our political organizationsbargain in
this fashion.
A second argumentasserts that each
farmerin our communitywould realize
that, if he adopted a maximizingpolicy,
this would lead all other farmersto do
the same. Since the "maximizingequilibrium"is worseforall9thefarmersthan
the "Kantian median," each farmer
would, on the basis of cold selfishcalculation, followthe Kantian system.This
argumentis similarto the view that no
union will forceits wage rate up because
each union realizes that such action will
lead other unions to do the same, the
eventualoutcomebeinghigherpricesand
wage rates but no increase in real income. There seems to be overwhelming
empiricalevidence that men do not act
thisway; in addition,the argumentcontains a logical flaw.This is the observation that, in any series of actions by a
number of men, there must be a first
one. If this can be prevented,then the
whole series can be prevented. This is
true,of course,but therealso must be a
second, a third,etc. If any one of these
is prevented,then the whole series cannot be carriedout. If all our 100 farmers
would refrainfroma maximizingcourse
of action because each one felt that his
personaladoptionof such a coursewould
lead to a switchto the "maximizingequilibrium,"then,if one of them had done
so, we could constructan exactly similar
argument"proving" that no 1 of the 99
remainingfarmerswould follow his example. But if this second argumentis
true,thenthe firstis false; and hence the
chain of reasoning contains an inconsistency.

part of the cost of which he will have to
bear. As a result,the whole effectof the
measureswhich resultfromhis bargains
and on which he votes on the winning
side will be beneficialto him. But this
will be only slightlymorethan halfof all
the "bargained" measures passed, and
the remainderwill be definitelycontrary
to his interest.The same would be true
forthe averagevoter under a pure referendum system.In fact, the whole problem discussed in this paper arises from
the system of corrpellingthe minority
to accept the will of the majority.
Althoughthispaper so farhas been an
exercisein "positivepolitics,"the analysis does raise importantpolicyproblems,
and at least some comment on them
seems desirable. It seems clear that the
