    RENT SEEKING AND THE

    PROVISION OF PUBLIC

    GOODS*

    Mark Gradstein

    Public good provision is a

    typical example

    of market

    failure, having served

    as

    an

    argument

    for

    government

    intervention since

    the

    time of

    John

    Stuart

    Mill

    (In Principles fPoliticalEconomy, ook V, Chapter

    XI).1 Many economists were

    quick

    to

    recognise

    the limits

    of

    government

    intervention and the

    corresponding

    causes of 'intervention

    failure'. One

    of

    these causes has to do with the

    observation that for reasonssuch as pressure by interestgroups (Becker, I983,

    i985),

    wasteful rent seeking (Tollison,

    i982),

    legislative failure (Fiorina and

    Noll,

    I

    978),

    and

    others,

    the

    government

    is

    unlikely

    to

    act

    purely

    in

    the

    interests

    of the

    public.

    These

    factorsquestion the validity

    of

    the benefits of

    government

    intervention relative to decentralised provision. To

    resolve

    the

    ambiguity

    pertaining

    to welfare

    enhancing possibilities

    of

    intervention,

    it

    is

    interesting

    to

    depart

    from

    models

    in

    which the

    government

    is

    represented

    in

    a

    purely

    benevolent manner and

    introduce some realistic features into the

    underlying

    political process.

    This

    approach

    has been

    emphasised

    in

    the

    writings

    of

    the

    public

    choice scholars

    (see, e.g. Buchanan,

    i968,

    and Buchanan and

    Tullock,

    I962). Pursuing this line of

    inquiry, a related recent paper (Gradstein, I992)

    presents

    a

    preliminary analysis

    of

    the effect

    of

    incomplete

    information on the

    welfarecomparison

    between public and private provision of public goods. The

    results are quite

    surprising: sometimes, even

    an extremely uninformed

    government performs well

    (and frequently even better) relative

    to

    the

    voluntary action of

    uninformed individuals.

    Incomplete information

    is

    only

    one

    among several

    reasons

    for

    the possible inferiority of intervention.

    An

    alternativelikely reasoninvestigatedin this paper is non-benevolent behaviour

    of the

    government.

    In

    this

    study,

    I

    adopt the public choice school

    paradigm

    of

    modelling the

    government

    in

    order

    to

    compare

    its

    performance

    with that of the market

    in

    the

    standard model of

    the

    provision

    of

    public goods. Specifically,

    I consider an

    economy

    consisting

    of

    jurisdictions

    which

    provide

    local

    public goods.

    Private

    provision

    is

    represented by the Cournot-Nash

    equilibrium

    in

    individual

    voluntary

    contributions towards the

    provision

    of

    public

    goods,

    whereas

    public

    provision entails

    influence costs. Specifically, it is assumed that levels

    of the

    public goods are determined by rent seeking activities, e.g. lobbying. Thus,

    both

    allocation

    procedures

    yield inefficiency,

    and the

    question

    is

    which

    procedure results

    in

    a

    greater

    amount of

    inefficiency: private provision

    with its

    free

    riding

    incentives,

    or

    public provision

    with its rent

    seeking

    incentives. The

    *

    I

    would like to thank

    two referees

    and the

    editor, John Hey,

    for

    their

    helpful

    comments

    and

    guidance.

    assistance from the Monaster Research Center is also

    gratefully acknowledged.

    The

    public goods

    that

    we

    have in mind are

    characterised

    by

    the absence

    of

    rivalry

    in

    consumption;

    in

    the

    particular example presented

    here

    they

    are

    pure

    local

    public goods.

    RENT SEEKING AND PROVISION OF PUBLIC GOODS

    I237

    particular modelling adopted is somewhat ad hoc, but nevertheless

    provides a

    useful frameworkfor the analysis of a

    realistic political process by which

    public

    decisions are

    made.

    The

    results

    indicate that

    government intervention is

    frequently preferred to private provision of public goods. Thus, the

    benefits

    from improved coordination, which centralisation is likely to bring about, may

    exceed the attendant influence

    costs. According to the results

    obtained,

    intervention is advantageous in

    large jurisdictions, especially when the number

    of these

    jurisdictions is small.

    In

    contrast, private provision can appear

    as

    welfare superior when jurisdictions are

    small,

    or

    when there are

    many

    jurisdictions.

    I

    conclude that

    superiority

    of

    private provision

    is not

    guaranteed

    when the

    government displays a forms

    of

    non-benevolent behaviour.

    This

    paper takes its perspective from

    the growing literature

    on

    rent seeking,

    which

    originated

    in

    the contributions of

    Bhagwati (I982), Krueger

    (I974),

    Posner

    (I975)

    and Tullock

    (I967, I980).

    Recent years have witnessed an

    increasing interest

    in

    the subject, as can be illustrated by many studies such

    as

    Applebaum

    and Katz

    (1986 a, b),

    Hillman

    and Katz

    (i

    984), Katz etal.

    ( I990),

    Nitzan

    (i

    99

    i),

    Tollison

    (i 982), Ursprung

    (

    1990).

    The

    papers of

    Katz et al.

    ( I990), Nitzan (i

    99

    i), and Ursprung

    (

    I990) are especially relevant since

    they

    touch on

    the public good aspect of rent

    seeking.

    The

    present contribution can

    be considered as an

    extension of

    their

    analyses.

    The

    novelty

    here is

    in

    presenting

    a welfare

    comparison

    of

    two imperfect allocation systems, whereas

    the above studies

    are

    mainly

    concerned

    with

    the extent of

    rent

    dissipation

    in

    the

    context

    of rent

    seeking

    for

    pure

    public goods.

    DESCRIPTION OF

    THE

    ECONOMY

    Consider an

    economy

    with

    N

    =

    kn

    individuals,

    where

    k,

    k

    >

    2,

    stands for the

    number of distinct

    jurisdictions, each

    of

    which is populated by n identical

    individuals. There are two types of goods

    -

    private and public.

    Each

    individual's initial endowment of the private good is w, and the initial

    amount

    of the

    public goods

    is zero.

    kjurisdiction-specificpublic goods

    can be

    produced.

    The

    production function of each of these goods is assumed to be a

    linear

    function

    of

    the

    average private good

    contribution

    in

    each

    jurisdiction,

    a

    common

    assumption

    in

    situations where the

    population

    size is allowed to

    vary.

    Letting

    xi

    denote the

    amount of contribution made

    by

    individual

    i

    to

    public

    goodj,

    and

    X,

    -

    the

    amount

    of

    public goodj,

    the

    assumption

    on the

    production

    function can be written as

    Xj

    =

    Yi

    x0j/n.

    Each

    jurisdiction

    is characterised

    by

    a different

    public good

    that the members

    of

    the

    jurisdiction prefer.

    In

    particular,

    the

    utility

    function of

    individual

    i

    which is identified

    with

    jurisdiction j (henceforth referred to as individual ij) is assumed to be

    quasilinear,

    that

    is,

    v(Xj)

    +yi,,

    where

    yij

    is the amount of that individual's

    private consumption.

    I

    make

    the

    following assumptions

    on

    v: v'

    >

    o,

    v

    <

    o,

    v(o)

    =

    o, v'(o)

    =

    00, v'(oo)

    =

    O.2

    All

    these

    assumptions

    are

    quite

    standard

    -

    see

    Cornes

    and

    Sandler

    (I986).

    Note that the

    public goods

    here are local

    public

    goods,

    one

    possible interpretation

    being

    in

    terms of a

    geographical separation

    2

    This

    particular

    form

    of

    utility

    function

    is

    adopted

    for

    simplicity

    of

    presentation.

    among

    districts populated by competing

    constituencies.3This model is

    similar

    to that of

    Ursprung (I990) who

    is

    also interested in

    the political economy of the

    provision of

    local public

    goods.

    Pareto efficiency requires maximisation of a

    representative individual's

    utility

    function, v(Xj)

    +yi,

    subject to the

    resource constraint,

    knyi1

    k(nX,)

    -

    knw

    o,

    which

    yields

    E '-1(I)

    (I)

    The

    Pareto optimal amount

    of each good is independent of the population

    size

    because

    of

    the

    assumptions

    made

    on

    the

    production technology.

    The

    symmetric

    yields

    =

    V(XE)

    +W_XE. (2)

    I

    now turn

    to the welfare

    analysis

    of

    private

    and

    public provision

    of

    public

    goods.

    II.

    WELFARE COMPARISON BETWEEN PRIVATE AND

    PUBLIC

    PROVISION

    OF PUBLIC GOODS

    This

    section presents

    an

    analysis of private

    provision, public

    provision,

    and

    then performs

    a

    welfare

    comparison between the two. Private

    provision is

    represented by a Cournot-Nash equilibrium in individual voluntary con-

    tributions

    towards

    the

    provision

    of

    public goods.

    The

    public provision requires

    each

    individual

    to

    participate

    in the

    provision

    of each

    public good

    on an

    equal

    basis,

    that

    is,

    the individual tax shares are

    equal.

    The amount

    of

    each of

    the

    public goods produced

    is then

    determined via

    a

    lobbying

    process,

    the details

    of

    which are

    specified

    below.

    II.

    I.

    Private

    provision

    In

    the Cournot-Nash

    equilibrium

    of

    the

    voluntary

    provision

    of

    public

    goods,

    individual ij chooses (x0,

    ye),

    so as to maximise v(X1)+yU, subject to x

    +yij

    =

    w.

    (Note

    that

    an

    individual

    residing

    in

    localityj

    will

    not

    make

    any

    contribution

    to

    public goods

    other

    thanj.)

    The

    Cournot-Nash

    equilibrium

    amount of

    public

    good j,j=

    I,...,k,

    is

    seen to be

    X;7N

    =

    vU'

    (n)

    =

    XCN.

    (3)

    This

    amount

    decreases

    in

    n

    because

    of the free

    riding

    incentives and is smaller

    than

    the

    socially optimal

    amount,

    v'1

    (I).

    The

    equilibrium utility

    level of each

    individual in a symmetric equilibrium is

    u

    N

    =

    V(XCN) +w-XCN

    Its

    derivative with

    respect

    to

    n

    is

    [VI

    (XCN)

    -

    I]

    (dXCN/dfl)

    =

    (n

    I)/lvf(XCN)

    <

    o,

    hence,

    this

    utility

    decreases with

    respect

    to

    the

    jurisdiction

    size.

    3

    Some authors (e.g.

    Fiorina and Noll

    (I978),

    and Weingast et al.

    (I98I))

    have argued that

    geographical

    separation is likely

    to

    result

    in a political failure due to the pork barrel politics

    generated by geographically

    based constituencies. Their argument,

    however,

    is only distantly related to rent seeking.

    RENT

    SEEKING AND PROVISION

    OF PUBLIC GOODS

    1239

    II.2.

    Public provision

    In

    this

    section

    I assume that members

    of group

    j

    are compelled

    to

    participate

    on

    an

    equal basis

    in

    the provision

    of each of the public

    goods

    that will be

    produced in the economy so that individual gs tax share is

    i

    /kn.

    This

    assumption

    may reflect the

    idea that

    income tax is used

    to finance

    the public

    goods,

    and that individuals

    who

    earn the same income

    are taxed the same,

    or

    it

    may

    reflect some other

    equity considerations

    of

    society.

    The level of each

    of

    the public goods

    that

    gets

    to

    he

    produced

    in the economy is determined

    by

    jurisdiction

    lobbying.

    Based on this premise, I depart

    from the standard

    public

    goods

    literature

    in

    which

    rent

    seeking

    efforts

    or

    other 'wasteful'

    activities are

    absent.4

    The incorporation

    of

    some types

    of socially 'non-optimal'

    behaviour,

    however, may sometimes

    better represent the

    realistic political

    situation.

    As is common

    in

    the rent seeking

    literature,

    I adopt a particular

    function

    form which

    transforms individual

    lobbying

    to the distribution

    of the tax

    burden.

    Specifically,

    the

    probability

    p1

    that

    public

    good

    j

    will

    be

    produced

    is

    a function

    of the

    lobbying

    efforts

    of group j

    relative

    to

    the total amount of

    lobbying. Letting

    zU denote the amount

    of lobbying

    of individual ij,

    and

    Z1

    the

    amount

    of

    lobbying

    of

    group

    j

    as a whole,

    we have

    p1

    =

    ZJ/Z,

    where

    Z1

    =

    Ei

    zU,

    and

    Z

    =

    Yj

    Z1.Public provision

    can be

    conceived as

    a

    two stage

    game,

    the

    first stage

    of which

    is the rent seeking competition among

    the

    jurisdiction,

    and

    the second stage is the optimal choice of the victoriousjurisdiction. Proceeding

    backwards,

    The

    is the case because

    when

    are

    more populous,

    individuals

    in each

    jurisdiction

    tend to

    free

    ride

    on the rent seeking

    efforts

    of other

    members

    of the jurisdiction,

    which,

    (9)

    the welfare

    difference

    _

    V(XCN)

    + XCN.

    (II)

    Since

    URS

    is

    an

    increasing

    function

    of

    n,

    and

    uCN is a

    decreasing

    function

    of

    n,

    the expressionin

    (i i)

    is an increasing function of the population size, which

    implies,

    once again,

    that

    public

    provision

    is welfare

    enhancing

    relative

    to

    private

    provision

    in

    a large

    economy.

    It

    follows

    from

    (3)

    that

    as

    the

    jurisdiction

    size increases

    to infinity,

    XCN

    decreases

    to

    zero. This,

    in

    turn, implies

    that

    as

    n tends to infinity,

    (i i)

    tends to

    [V(XRS)

    -XRS

    ]/k > o, that

    is,

    when

    the

    group

    size is sufficiently

    large, public

    provision

    always performs

    better

    than private

    provision

    does.

    Since

    URS

    is a decreasing

    function

    of k, and

    uCN s a

    constant

    function

    of

    k,

    it follows

    that the larger

    the number of

    interest groups,

    the better

    private

    provision

    performs

    relative

    to public

    provision.5

    I

    conclude

    with

    an

    illustrative

    example,

    Let

    v(X)

    =

    Xx,

    o

    <

    <

    i.

    Then

    The parameters are chosen so as to ensure positive public levels in the public provision case.

    presented

    in

    Table i. This table vividly illustrates our general conclusions,

    namely, that private provision is preferable when jurisdictions are small, and

    public provision performs

    better when there is a small number

    of

    large

    jurisdictions.

    III. DISCUSSION AND EXTENSIONS6

    Some

    assumptions

    made

    in

    this

    paper

    deserve

    a closer look as

    they

    are the

    driving

    force

    behind

    the

    results.

    First,

    there is the

    assumption

    on

    strictly

    non-

    cooperative

    behaviour

    of

    individuals

    -

    both

    in

    their

    private provision

    of

    public

    goods

    and

    in

    their rent

    seeking

    efforts. Were more

    'cooperative' equilibrium

    concepts

    used,

    private provision

    would

    become more

    attractive

    and

    public

    provisionmore wastefulsince free riding varies negatively and rent dissipation

    varies

    positively with cooperative

    behaviour.

    In

    the context

    of

    private

    provision of public goods, several attempts have been made to model the

    individual's behaviour

    in

    a

    more

    cooperative way than is suggested by

    the

    Cournot-Nash

    paradigm

    -

    see, e.g. Sugden

    (i

    984)

    for one such

    alternative

    equilibrium concept.

    A

    related

    line

    of research

    in

    the

    public goods

    literature

    departs

    from

    the neoclassical tradition

    by assuming

    that

    individuals

    make their

    contributions to the

    provision

    of

    public goods partly

    because of

    'egoistic'

    motives,

    that

    is, they

    derive

    utility

    from the act of contribution

    as well as from

    private and public goods

    -

    see, e.g. Andreoni (I989)

    and

    references therein.

    Proceeding along

    these lines

    may

    also

    increase

    the attractiveness

    of

    private

    provision, especially in those circumstances where the 'egoistic' motive is

    relatively important.

    It is

    equally plausible

    to

    approach

    rent

    seeking

    with the

    aid

    of

    some

    kind of

    cooperative equilibrium concept

    since

    lobbying

    is

    usually

    done

    by

    a

    relatively

    small number of

    (sometimes

    well

    organised

    and

    disciplined)

    groups

    of individuals

    -

    see Olson

    (I982)

    who

    stresses

    the

    importance

    of the

    interest

    groups' organisation

    for economic

    growth.

  • 8/9/2019 Rent Seeking and the Provision of Public Goods

    8/9

    1242

    THE ECONOMIC JOURNAL

    [SEPTEMBER

    Another

    possible extension is to

    represent

    rent seeking as lobbying

    over

    shares

    of

    the public good

    (as

    in

    Ursprung

    (I990)). For example,

    suppose that

    the government

    sets the

    amount of public good provision, whereas

    individuals

    attempt

    to affect the

    distribution of the tax

    burden. More precisely,

    an

    individual's share in public good provision can be affected by rent seeking

    individuals with the

    assumption that

    the individual's tax share

    is a decreasing

    function

    of

    his own

    lobbying and an increasing

    function

    of lobbying by others.

    A

    preliminary

    analysis

    done by the author

    along these lines

    indicates that our

    main conclusions are

    unaffected. A more promising

    possibility

    is to assumethat

    individual

    rent seeking

    efforts are, at least, partly

    an input

    in

    the provision

    function

    of

    the public

    good, as was suggested

    in

    a related context by Long

    and

    Vousden (I987).

    This seems to be an interesting

    line of research

    to

    pursue

    in

    future work.

    Finally, relaxing the

    assumption

    of identical individuals may

    yield interesting

    results as to the effect

    of heterogeneity

    in

    initial wealth

    on the welfare

    comparison

    between

    private provision

    of

    public goods

    and

    public provision

    with

    rent

    seeking.

    In this

    case,

    both outcomes could

    also be

    compared

    to that

    attained by direct voting,

    where the

    median voter

    is

    pivotal

    in

    determining

    the

    final allocation

    of resources.

    IV. CONCLUDING

    REMARKS

    The

    main

    objective

    of this

    paper

    is

    to

    approach

    the issue

    of

    government

    intervention

    in the provision of public

    goods

    from a positive perspective,

    by

    introducing

    some realistic features

    into the underlying political process.

    Following the paradigm

    developed by the public

    choice

    school, this study

    is

    based

    on

    the

    presumption

    that

    public provision

    of

    public goods

    entails wasteful

    rent seeking.

    The results

    supplement those of

    a related work (Gradstein, I992)

    which

    contains a

    preliminary

    discussion

    of

    the

    comparison

    of

    private

    and

    public provision

    of

    public goods

    when the

    government

    is uninformed.

    In both

    cases, public provision frequently outperforms private provision in large

    economies.

    The amount

    of

    inefficiency generated by

    rent seeking

    incentives

    is

    much smaller here than

    in the

    context

    of rents having

    the nature

    of

    private

    goods.7

    The

    presented

    model

    illustrates, therefore,

    that

    in

    the case

    of

    public

    goods provision,

    rent

    seeking

    behaviour

    does

    not

    necessarily

    impair

    the welfare

    enhancing potential

    of

    centralised

    intervention.

    Since

    public provision

    is nevertheless inefficient

    because

    of influence activities,

    the ideal

    of

    organisation

    would probably try
