regulatory reform in britain regulatory reform in britain john kay and john vickers major sectors of the british economy are currently undergoing far reaching regulatory reform deregulation removal of barriers to competition and the introduction of new methods of regulation are occurring notably in financial services some of the professions and in utility industries such as telecommunications gas and electricity this paper gives an economic assessment of these developments the authors examine the root causes of market failure that call for regulation externalities monopoly and information problems and the pros and cons of various regulatory responses a broad distinction is drawn between structural regulation the determination of which firms or types of firms can engage in which activities and conduct regulation the control of how firms behave in their chosen activities recent examples of deregulation plus re regulation in britain are seen in part as a shift from structural to conduct regulation the relative merits of the two modes of regulation are complex to assess but it is argued that some recent regulatory reforms are placing undue reliance on conduct regulation as well as assessing individual industries the authors draw general conclusions about the desirability of regulatory solutions that make full use of market forces

a cooperative game approach to optimal saving theory toward a constitution for savings 1 two years ago after a post nobel conference at the university of turin james buchanan told me that he was working on pure allocational grounds on the economic foundations of two ethical principles defined as victorian principles or virtues and comprised the ethics of work and the ethics of savings 1 he reasoned that the allocational foundation of the ethics of work should mainly be found in the external economies of increasing returns related to the increase in labour supply as for the allocational foundations of the ethics of savings the arguments where those previously used in the extensive discussion of the failures of the keynesian democracy in deficit and of the reasons of constitutional fiscal rules see brennan and buchanan 1985 buchanan and wagner 1977 the foundations of these virtues therefore are intended to be strictly paretian or rather taking buchanan s contractarian constitutional point of view wicksellian encouraged by buchanan s lead i aim in this paper to find rules relating to optimal saving in terms of an ideal game equilibrium which results both in pareto efficiency and fairness to the parties involved who are the individuals living in the various periods of time in a given country or society fair here means a distribution according to rules of justice as impartiality or mutual advantage i e when the players do not exert any threat or pressure arising from their different bargaining power 2 my approach although analogous to that of buchanan does differ because rests on rules of justice consistent with pareto improvements which due to these characters might have a salience as stable conventions 3

federal borrowing and short term interest rates this paper is an empirical study of the effects of federal government borrowing on short term interest rates it is often taken for granted that increases in federal borrowing cause higher short term rates but little empirical support exists for this assumption in fact this paper demonstrates that federal borrowing is a relatively unimportant and insignificant determinant of short term rates an implication of this result is that financial crowding out effects of government deficit spending may not be overly large postulates about interest rate behavior are the driving force behind many hypotheses of the crowding out literature however these interest rate effects have received relatively little direct attention in this literature this is surprising since as a general rule the stronger the interest rate effect is the stronger the crowding out effect will be an empirical determination of the size of the deficit spending interest rate effect gives some empirical content to the crowding out controversy in section ii of this paper the relationship between federal borrowing interest rates and crowding out is discussed and a loanable funds model of short term interest rates is developed in section iii the regression model is generated and tested the essential result is that variation in three month treasury bill rates is caused by expected inflation changes in the monetary base and by changes in the level of economic activity there is no statistically significant relation between short term interest rates and federal borrowing in section iv additional regression tests are performed which confirm the results in section iii and the problem of simultaneous equation bias is discussed the final part of the paper is a discussion of some implications of the results reported in sections iii and iv

some microeconomic evidence concerning the determinants of saving through private pension funds in the u s abstract this note presents some new evidence about determinants affecting the contributions to private pension plans through the bargaining process employer decisions about pensions reflect employee preferences according to our estimation results on a time series basis there is a clear significant relationship between the firm variables social security taxes and saving through private pension plans

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

new tests of the life cycle and tax discounting hypotheses abstract we first test a version of the permanent income consumption function recently suggested by barro the results support the theory except that consumption expenditures show sensitivity to transitory income next we use the consumption model to test the tax discounting hypothesis which is strongly supported this support for tax discounting disagrees with results from some earlier studies using more traditional specifications of the consumption function however we show that when certain obviously inadequate estimation procedures are corrected the traditional models also support tax discounting this uniform support for tax discounting suggests that the sensitivity of consumption to transitory income is not due to liquidity constraints

satisfaction guaranteed or money partially refunded efficient refunds under asymmetric information refunds are modelled as a competitive market response to asymmetric information firms have private information on their choice of product quality and compete by offering price and refund contracts consumers who care about quality draw inferences about the quality offered by the various firms from observed contracts conditions under which a revealing market equilibrium emerges are specified and the equilibrium quality and contract s characterized the model predicts that when product risk is not insurable consumers with higher incomes will pay higher prices for higher quality goods with higher refunds if the product fails

gratitude conscience and reciprocity models of supplier motivation when quality is non contractible abstract standard game theoretic models that apply principal agent problems to analyse buyer supplier relations have postulated that in a single period game the agent will not choose non contractible quality however evidence exists that suppliers or service providers choose costly quality in non contractible dimensions even in absence of reputation concern if they are offered a premium such actions violate the axiom of individual rationality and are not subgame perfect in standard game theory wherein only material payoffs are considered this paper builds three models of supplier behaviour in a single period stackelberg like buyer supplier game by using the framework of psychological game theory and explains supplier motivations to choose quality on non contractible dimensions in absence of any reputation effect if the buyer offers a price higher than the market price the supplier may be motivated to choose non contractible quality due to a sense of gratitude or because of his conscience or in order to reciprocate kindness the results show that maximum possible quality is chosen by the supplier only in the presence of a sufficiently strong sense of gratitude or a sufficiently strong conscience however the buyer is better off with a fair supplier who is motivated to reciprocate than a supplier having a very poor sense of gratitude or one having a weak conscience because the buyer can choose an optimal premium above market price to ensure that a fair and reciprocal supplier chooses an optimal quality

gift giving and the evolution of cooperation gift giving is a practice common to many societies in an evolutionary model the social custom of giving gifts at the beginning of a relationship can lead to trust and cooperation the evolutionary approach makes predictions about the character of the goods that can be used as gifts for example gift goods may have little use value even at low levels of consumption although the gifts themselves are useless the institution is not

symposium on the budget deficit when ronald reagan assumed the presidency in 1981 the federal government s outstanding gross debt amounted to 909 billion or 33 3 percent of gnp by the end of 1987 as a consequence of federal budget deficits averaging 4 5 percent of gnp between 1981 and 1987 the ratio of debt to gnp had risen to 51 8 percent in contrast during the period between 1947 and 1981 the federal deficit only once exceeded 4 percent of gnp the net international investment position of the united states also deteriorated dramatically during the reagan years in 1981 the u s was a net international lender however a succession of increasingly large deficits in the current account of the u s balance of payments between 1982 and 1988 caused the united states to switch from creditor to debtor status u s net international indebtedness at the end of 1987 is estimated at 368 billion in the view of most of the nation s economists these developments are profoundly disturbing harvard economist benjamin friedman 1988 summarizes the majority opinion when he writes we are living well by running up our debt and selling off our assets america has thrown itself a party and billed the tab to the future the costs which are only beginning to come due will include a lower standard of living for individual americans and reduced american influence and importance in world affairs is the ballooning federal budget deficit a serious economic problem the papers in this symposium provide four perspectives on this issue robert barro and robert eisner disagree sharply with the majority opinion concerning deficits in contrast edward gramlich and douglas bernheim are more sympathetic to the view that budget deficits lower national saving and thus contribute to a reduction in future living standards

visits to the client when competing for new consulting contracts sourcing information or influencing the client consulting firms cfs sell services on a project basis to many clients and must therefore continuously tender for new contracts one frequently used strategy by cfs is to visit the clients in connection to the tenders the reasons to the visits are 1 to influence the client in his decision making e g marketing bribing and or 2 to source information about the project so that a better proposal can be submitted using a unique database on individual export proposals submitted to emerging markets which of these two reasons is the most important is examined empirically the estimations show that influencing the client dominates as explanation to the visits although it is not possible to determine whether this influence takes the form of bribing or marketing all conditions necessary for bribes to occur are fulfilled

material interests moral reputation and crowding out species protection on private land we consider how the reputation of being socially responsible works as an effective source of motivation in protecting a public good such as endangered species this paper investigates the mechanism design for endangered species protection on private land under asymmetric information about reputation and land quality we examine optimal monetary transfer by designing an efficient mechanism which takes into account the crowding out effect of monetary rewards on socially responsible behavior we find landowners who have good reputation contribute more than the optimum level landowners with poor reputation sacrifices information rent rather they buy reputation

the ricardian equivalence hypothesis evidence from bangladesh this article examines the ricardian equivalence hypothesis reh and its sources of failure in the case of bangladesh using various theoretical specifications annual data from 1974 2001 and linear and nonlinear time series techniques the general findings tend to invalidate the reh a finite time horizon and the presence of liquidity constrained individuals are the sources of deviation from the reh empirical results reveal that real per capita private consumption c under various specifications is cointegrated generally at the 5 level with real per capita income y government expenditure before and after interest rate repayments g and g2 taxes t and the interest rate r results reveal that an increase in g g2 t and r reduces c and that an increase in budget deficits raises trade deficits these results highlight the importance of fiscal policies in boosting private consumption and controlling trade deficits which are the prime goals of stabilization policies being followed by bangladesh

why corporations insure corporations insure to reduce the shirking information problem of joint production insurance encourages specialization in ownership increasing the returns to monitoring and lowering shareholders demand for a more diversified portfolio it enhances the credibility of specific capital as a performance bond and it lowers the cost to shareholders of compensating other members of the team for investing in firm specific assets tax and other factors may further encourage individual corporations to insure

is antitrust enforcement effective in a paper in this journal block nold and sidak 1981 tried to determine the impact of antitrust enforcement on horizontal price fixing after examining data on white bread markups in 20 u s cities they concluded that the enforcement activity of the department of justice against wholesale bakers had both remedial and deterrent effects in this paper i question the authors empirical results for three reasons they used bureau of labor statistics bls retail prices in computing bread markups however the white bread priced by the bureau changed quality over the sample period when a proxy for this quality change is included in the authors specification one deterrent effect disappears second the bread markups are sensitive to the pricing decisions made by grocery retailers when a proxy for retail pricing decisions is included in the model the deterrent effects are weaker finally the significance of the remedial effect depends on a single observation and this observation was affected by the two problems just stated

household saving out of different types of income revisited the purpose of this paper is to test for two hypotheses about household consumption and saving behaviour namely the substitution hypothesis according to which changes in corporate retained earningshave an offsetting effect on household savingand the hypothesis that consumption and saving out of different types of income vary cross country evidence from 13 oecd countries over the period 1963 80 lies very well in accordance with both of these hypotheses moreover results are robust to alternative specifications of consumption function to additional variables and to estimation methods

on barro s theorem of debt neutrality the irrelevance of net wealth the effects of national debt on real economic activity has been a recurring topic in the literature on macroeconomic policy analysis since the time of adam smith the problem is usually stated as follows for a given level of government spending is the economy sensitive to the financing mix between tax and debt historically attention has focused on the question of whether or not individuals perceive government bonds as net wealth the link between wealth and real activity being taken as given the main point of debate is well established the issue of bonds raises private assets by the full value of the bonds the corresponding tax liabilities for interest payments and retirement of the debt extend indefinitely into the future the perception of bonds as net wealth would then appear to depend on the length of the individual s optimization horizon the most recent contribution to this debate was made by robert barro 1974 in which he argued that despite the limitation of finite lives bonds will not be regarded as net wealth in a system characterized by operative intergenerational transfers the essence of his argument is that inclusion of a bequest motive effectively converts a finite horizon into an infinite one in that paper barro acknowledged a potential limitation on his proof of the neutrality result it was only valid for bonds that are redeemed at a known point in the future this limitation was raised again in a subsequent exchange with martin feldstein in which barro 1976 agreed that for a growing economy an increase in steady state per capita debt will generate net wealth if the rate of growth is greater than the interest rate however he argued that such a steadystate growth situation would not be consistent with rational utility maximizing behavior the main theme of this paper is that the literature has focused attention on the wrong question the real effects of national debt are independent of whether or not individuals perceive the debt as net wealth the correct question is whether or not changes in the level of debt force individuals into patterns of intertemporal consumption that they are unable to neutralize by adjustments in their portfolio behavior viewing neutrality in this light leads to some reinterpretation of the conditions under which neutrality is likely to hold my analysis starts where barro and feldstein leave off within the framework of the overlapping generations model with gift and bequest motives i show that steady state equilibrium growth is consistent with a growth rate in excess of the interest rate indeed without specific knowledge of the parameters of the economy there are no a priori grounds on which to expect any particular relationship between the growth and interest rates more importantly so long as it is valid to view the aggregate economy as behaving like a composite individual changes in the steady state level of government debt are neutral regardless of which relationship prevails provided one or the other of the intergenerational transfer motives is operative i will refer to this as the extended neutrality theorem section i presents an analysis of steadystate growth with gift and bequest behavior the steady state growth path is shown to lie above the golden rule solution if the gift

federal deficits and the real rate of interest in the united states a note this brief note provides strong empirical evidence that federal govern ment deficits can indeed have a positive and significant impact upon short term interest rates the findings in this paper thereby establish another mechanism for the transmission of crowding out this study differs from most other studies in the adoption of two particular procedures first unlike most although not all other related studies the rate of interest is expressed as a real rate this is done in simple fashion by subtracting the inflation rate of the gnp deflator from the nominal rate of interest taken to be the 3 month t bill rate second also unlike most although not all other related studies the deficit is expressed in real terms and then divided by the real gnp level expressing the deficit in this ratio form enables us to judge the deficit relative to the size of the economy which must finance it no previous related study to date has adopted both of these procedures and most studies of this topic have adopted neither procedure

the ricardian approach to budget deficits persistent budget deficits have increased economists interest in theories and evidence about fiscal policy this paper develops the ricardian approach and contrasts it with standard models the discussion considers from major theoretical objections to ricardian equivalence finite lifetimes imperfect capital markets uncertainty about future taxes and incomes and the distorting effects of taxation the paper then considers empirical evidence on interest rates consumption and saving and current account deficits the conclusion is that the ricardian approach is a useful first order approximation and that this approach will probably become the benchmark model for assessing fiscal policy this abstract was borrowed from another version of this item

assessing ricardian equivalence this paper reviews the literature on ricardian equivalence this hypothesis may be interpreted as a generalisation to the short and the long run of the theories which put no weight on the real effects of public policies on aggregate demand we argue that ricardian equivalence relies on both permanent income hypothesis and the fulfilment of the intertemporal government budget constraint the theoretical literature emphasises several reasons for departures from this hypothesis however the empirical literature is inconclusive when ricardian equivalence is tested in a life cycle framework the hypothesis is usually rejected while when the empirical analysis is based on optimising models it is usually accepted

on the intergenerational allocation of natural resources it is known hartwick and others that under standard assumptions a society that invests in reproducible capital the competitive rents on its current extraction of exhaustible resources will enjoy a consumption stream constant in time it is shown here that this result can be interpreted as saying that an appropriately defined stock of capital including the initial endowment of resources is being maintained intact and that consumption can be interpreted as the interest on that patrimony this seems like a useful rule of thumb for policy

two part pricing for experience goods in the presence of adverse selection abstract because customers learn something when they purchase an experience good for the first time a firm selling experience goods may face different demand curves from new and repeat customers the firm can exploit these differences by using a two part pricing strategy to price discriminate between new and repeat customers the firm may also use a two part pricing strategy to mitigate the information problems of adverse selection when its quality is uncertain the analysis is particularly applicable to service markets where customers and firms seek long term relationships and firms maintain customer records which facilitate price discrimination

physician price fixing under the sherman act an indirect test of the maricopa issues the expression price fixing usually indicates an attempt by competitors to put a floor under the minimum price they will charge but a recent decision of the supreme court arizona v maricopa county suggests that attempts to fix maximum prices are equally economically objectionable in this paper i propose an explanation of simultaneous minimum and maximum price fixing i also investigate empirically the distribution of physicians fees in a closely related instance of alleged physician price fixing the data reject any inference of successful price fixing and instead conform to the usual predictions of the economics of costly market information

the shape of advertising response functions revisited a model of dynamic probabilistic thresholds prior work in marketing has suggested that advertising threshold effects levels beneath which there is essentially no sales response are rarely encountered in practice because advertising policies settle into effective ranges through early trial and error thresholds cannot be observed directly and arguments for their existence must be based primarily on a statistical footprint that is on relative fits of a range of model types to detect possible threshold effects we formulate a switching regression model with two regimes in only one of which advertising is effective mediating the switch between the two regimes is a logistic function of category specific dynamic variables e g order of entry time in market number of competitors and advertising levels nesting a variety of alternative formulations among them both standard concave and s shaped responses a sequence of comparisons among parametrically related models strongly suggests that threshold effects exist that market share response to advertising is not necessarily globally concave that superior fit cannot be attributed to model flexibility alone and that dynamic environmental competitive and brand specific factors can influence advertising effectiveness these effects are evident in two evolving durables categories suvs and minivans although not in the one mature nondurable category liquid detergent studied

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

relational incentive contracts standard incentive theory models provide a rich framework for studying informational problems but assume that contracts can be perfectly enforced this paper studies the design of self enforced relational contracts i show that optimal contracts often can take a simple stationary form but that self enforcement restricts promised compensation and affects incentive provision with hidden information it may be optimal for an agent to supply the same inefficient effort regardless of cost conditions with moral hazard optimal contracts involve just two levels of compensation this is true even if performance measures are subjective in which case optimal contracts terminate following poor performance jel c73 d82 l14

debt deficits and inflation an application to the public finances of india abstract the paper studies the solvency of the indian public sector and the eventual monetization and inflation that would be implied by stabilization of the debt gnp ratio in the absence of changes in the primary deficit the nonstationarity of the discounted public debt suggests that indefinite continuation of the pattern of behavior reflected in the historical time series process is inconsistent with the maintenance of solvency this message is reinforced by the recent behavior of the debt gnp ratio and of the ratio to gnp of the sum of the primary budget surplus and seigniorage our estimates of the base money demand function suggests that even maximal use of the inflation tax would not be sufficient to restore solvency measures to reduce the primary deficit are therefore unavoidable

productivity change technical progress and relative efficiency change in the public accounting industry we present evidence on components of productivity change in the public accounting industry toward the end of the 20th century using revenue and human resource data from 64 of the 100 largest public accounting firms in the united states for the 1995 1999 period we analyze productivity change technical progress and relative efficiency change over time the average public accounting firm experienced a productivity growth of 9 5 between 1995 and 1999 we find support for the hypothesis that technical progress rather than an improvement in relative efficiency was the reason for this productivity growth firms that were early movers into management advisory services mas and those that emphasized growth in mas over growth in the traditional audit and tax services enjoyed significantly higher productivity growth than their peers these firms also contributed significantly more to the industry s technical progress

globalization and household saving is there a link abstractthis article proposes that globalization can affect household saving in the long run in a number of ways social interactions between different cultures can induce value changes which can result in shifts in consumption and saving behaviour international trade allows consumers to have easier access to status goods stimulating consumption and dampening saving extending from veblen s conspicuous consumption theory saving may also decrease when globalization leads to greater population mobility and fosters urbanization thus enhancing the importance of consumption as a way to display wealth in addition financial globalization reduces credit constraints and allows households to save less using cross country data from the united nations un the oecd and other sources this article finds evidence that household saving declines as globalization deepens especially in the social and cultural dimensions

budgetary deficits and ricardian equivalence the case of india 1950 1986 abstract in this paper we analyze the validity of the ricardian equivalence re theorem for a less developed country ldc i e india for the period 1950 1986 the re theorem states that it is inconsequential whether a government deficit is financed by debt issue or by tax increases since under certain conditions the effect of government consumption on aggregate demand is orthogonal to the mode of financing fiscal deficits because rational economic agents consider today s deficit financing as tomorrow s tax liabilities the use of multicointegration analysis and estimation of the rational expectations model both invalidate the re hypothesis in india there are significant crowding out effects on private consumption but such effects on private investment are insignificant because they are expected to be already included in the effect of interest rates

price quality and reputation evidence from an online field experiment we examine the link between price quality seller claims and seller reputation in internet auctions after purchasing actual baseball cards and having them professionally graded we find that some buyers in the online graded market are misled by incredible claims of quality they pay higher prices but do not receive better quality and in fact are defrauded more often online seller reputation is effective for identifying good faith sellers but conditional on completed auctions reputable sellers do not provide better quality evidence also suggests that high claim sellers target less experienced buyers we attribute these patterns to two loopholes in the ebay rating system we benefited from the comments of austan goolsbee raphael thomadsen john shea dan vincent david reiley larry ausubel peter cramton v joseph hotz jeff smith jimmy chan vincent crawford mark duggan and attendees at numerous seminars and conferences we are particularly grateful to seth sanders and john list for their constructive advice at the early stage of the research to timothy bresnahan rachel kranton and thomas hubbard for their detailed suggestions in reshaping earlier versions and to editor ariel pakes and two anonymous referees for their careful readings special thanks to eight friends who acted as our agents in purchasing baseball cards in retail markets and to numerous sports card store owners who shared their insights on the sportscard industry excellent research assistance from randy alexander moore and krzysztof fizyta is gratefully acknowledged any remaining errors are ours

short term contracts and long term agency relationships abstract long term contracts are valuable only if optimal contracting requires commitment to a plan today that would not otherwise be adopted tomorrow we show that commitments are unnecessary and hence short term contracts are sufficient if 1 all public information can be used in contracting 2 the agent can acess a bank on equal terms with the principal 3 recontracting takes place with common knowledge about technology and preferences and 4 the frontier of expected utility payoffs generated by the set of incentive compatible contracts is downward sloping at all times

government deficits and aggregate demand abstract the evidence presented in this paper indicates that changes in government spending transfers and taxes can have substantial effects on aggregate demand the estimates also indicate that the promise of future social security benefits significantly reduces private saving each the basic implications of the so called ricardian equivalence theorem is contradicted by the data the results are consistent with the more general view of the effects of fiscal actions and fiscal expectations that is described in the paper

prices as signals of product quality this paper is concerned with the provision of quality in markets in which consumers have only imperfect information the analysis focuses on a market for a product that can be produced at different quality levels all consumers prefer higher to lower quality but they may differ in their willingness to pay for quality producers can produce any quality they like but higher qualities are more costly to produce the information in this market is imperfect in the sense that the exact quality chosen by a firm is known only to the firm itself some information about the quality of a firm s product will however reach its potential customers even if they do not make any special effort to acquire it within the framework suggested here two conclusions are drawn first prices may serve as signals which exactly differentiate the available quality levels that is there exists a fulfilledexpectations equilibrium at which each price signals a unique quality level second the pricesignals are not arbitrary each price signal exceeds the marginal cost of producing the quality it signals such a mark up depends on the nature of the product specific information received by consumers the poorer the information the higher the mark up

investing to cooperate theory and experiment we study theoretically and in a lab experiment investment decisions in environments where property rights are absent in our setting a player chooses an investment level before interacting repeatedly with a given set of agents the investment stochastically affects the payoffs of the game in every subsequent period we show that more volatile returns make investment more difficult in the absence of legal protection and might force the investor to invest more to guarantee cooperation experimental results are broadly consistent with the theoretical findings

competition and the incentive to produce high quality previous literature indicates that when quality is a choice variable firms have an incentive to produce high quality to maintain their reputations with consumers the strategic interaction among firms and competition for market share is not considered this paper finds that when firms compete for market share perfect equilibria in which firms produce high quality goods need not exist competition for customers can eliminate the price premium needed to induce firms to maintain a reputation for high quality production in this case economists and policy analysts should pay greater attention to the interaction among firms and the institutions such as professional associations that structure interfirm relations when considering whether firms have an incentive to produce high quality goods

government debt government spending and private sector behavior a current period tax reduction financed by issuing government debt shifts the timing of tax collection from the current period to the future if the future taxes implied by government debt are not fully perceived and discounted by the private sector there will be a net wealth effect that increases private sector consumption thus reducing capital accumulation and growth if on the other hand the implied future taxes are perceived and discounted by the private sector the current period tax reduction will be used to increase private saving to pay for the future taxes and government debt will be absorbed without any real effects on the economy the effects of government spending financed by current period taxation also depend upon private sector perceptions 2 if the benefits of government spending are ignored private sector consumption will decrease in accordance with the reduction in permanent disposable income to the extent that government spending is on consumption type goods that are perceived as substitutes for privately provided consumption goods there will be a relatively greater reduction in private sector consumption to the extent that government spending is on investment type goods yielding future goods and services that are perceived as substitutes for future privately provided consumption goods there will be a relatively smaller reduction in private sector consumption the standard approach to modeling private sector consumption saving behavior involves a rather asymmetric set of assumptions as to how the private sector perceives the various elements of government fiscal policy 3 current period taxes are assumed to be fully perceived but current period government spending is implicitly assumed to be completely ignored by the private sector in considering permanent personal disposable income the private sector is assumed to be forward looking in its assessment of income and taxation the stock of government debt is nevertheless included as part of the stock of private wealth the implicit assumption associate professor of economics graduate school of business university of chicago 1101 east 58th street chicago il 60637 i thank eugene fama levis kochin michael mussa paul evans and an anonymous referee for helpful comments i am particularly grateful to daniel benjamin for contributing many hours of discussion and laura lahaye who was a research assistant and valuable adviser on earlier drafts the theoretical debate on the burden of the debt has been long standing gerald o driscoll 1977 documents ricardo s nineteenth century position robert barro 1974 reopened the debate by introducing the fundamental issue of intergenerational transfers also discussed in merton miller and charles upton 1974 the empirical side of the debate was initiated by levis kochin s 1974 attempt to test for the effects of deficits on consumption and by martin feldstein s 1974 attempt to test for the effects of social security wealth on consumption other empirical contributions include jess yawitz and laurence meyer 1976 myself 1978 and j earnest tanner 1978 1979 with respect to the effects of government deficits and debt and barro 1978 michael darby 1979 and dean leimer and selig lesnoy 1982 with respect to social security wealth see also interesting recent papers by john seater 1982 who generates detailed tests of the effects of deficits and debt on consumption charles plosser 1982 who explores the effects of government spending and debt shocks on interest rates and feldstein 1982 who attempts tests similar to some in this paper see fn 29 2martin bailey s 1962 1971 development of the effects of government spending on private consumption and aggregate economic activity is the seminal contribution paul david and john scadding 1974 extend bailey s ideas and provide some supporting empirical evidence more recently willem buiter 1977 and myself 1978 developed models based on bailey s earlier work barro 1981 has an interesting paper on related issues see also david aschauer 1982 3the standard approach incorporates fiscal policy through the concept of personal disposable income and by including the stock of government debt as part of personal wealth see for example the empirical specification of albert ando and franco modigliani 1963 which has been the basis of most empirical consumption studies since and feldstein 1974 for one of the more influential papers based on the ando modigliani specification

a note on long term determinants of the private savings ratio abstract this note presents some new evidence about cross country differences in the private savings ratios opposite to claims forcefully proposed e g by feldstein social security benefit variables do not contribute to explain these differences instead our results suggest that variables describing degree of development of monetary systems perform strikingly better according to our estimation results there is a clear positive relationship between these variables and the private savings ratio

information and the provision of quality differentiated products governments often enact information provision policies to overcome asymmetric information of product qualities we show that increasing awareness among consumers of the quality of a good can but will not always encourage firms to produce goods with higher levels of quality even if product qualities increase social welfare may fall as information provision results in too much product differentiation we show that the effectiveness of emission taxes and output subsidies are affected by the level of consumer knowledge of product quality and we identify conditions under which information provision is welfare enhancing relative to these price instruments jel l15 q58 i introduction in the past 20 years consumers have become increasinglyconscious ofthe undesirable health and safety attributes of the products they consume and surveys suggest that a growing percentage of consumers are willing to pay more for higher quality products such as organic foods and household cleaners and detergents that contain less toxic ingredients guber 2003 other high quality products facing higher demand include energy efficient products like extended life lightbulbs and improved home insulation often these highquality products provide private benefits that are excludable to buyers as well as public benefits that are nonrival and nonexcludable for example reduced pesticide and chemical residue on food may lower the risk of cancer while also reducing contaminated run off that degrades ground and surface water quality extended life lightbulbs and improved home insulation may reduce an individual s utility bill while also reducing greenhouse gas emissions from lower energy consumption although interest in these types of high quality productsisgrowing demand isoften relatively small market shares of organic produce for

the market value of rarity abstract most theories of demand assume that consumers value the characteristics of products but are unconcerned with how many other consumers also consume the product however several theories of demand argue that consumers can value the exclusivity of possessing a rare object we test this implication on a particular collectible rare coins our paper examines the case of coins of a given type and identical quality that have mintages in different quantities this allows us to exclude the common case in which rarity or price itself is an indicator of quality for our sample rarer coins command higher prices rarity in the form of original mintage more strongly influences the market price than does collectibility as represented by the rarest coins of each mint mark or year we also point out that here may be other goods such as automobiles for which rarity may influence market demand

community enforcement of trust with bounded memory we examine how trust is sustained in large societies with random matching when records of past transgressions are retained for a finite length of time to incentivize trustworthiness defaulters should be punished by temporary exclusion however it is profitable to trust defaulters who are on the verge of rehabilitation with perfect bounded information defaulter exclusion unravels and trust cannot be sustained in any purifiable equilibrium a coarse information structure that pools recent defaulters with those nearing rehabilitation endogenously generates adverse selection sustaining punishments equilibria where defaulters are trusted with positive probability improve efficiency by raising the proportion of likely re offenders in the pool of defaulters

imperfect competition and reputational commitment abstract competition can both aid and hinder reputational commitments for quality these are self sustaining depending on future profits after maintaining or deviating from the commitment and on current costs of sustaining it competition can affect these three elements at different rates

marital division of labor with risk of divorce the role of voice enforcement of contracts it is assumed that emotional ties can be relied on to enforce implicit marital contracts by voice therefore in the present model divorce has economic consequences not only because the economies of scale from living together are destroyed but also because the scope for such voice enforcement is weakened moreover perhaps surprisingly i find that it is ambiguous how an increase in the probability of divorce influences predivorce allocation of time even when preferences are assumed to be homothetic

crowding out deficits and interest rates comment cebula s investigation along with the work of the other participants in this controversy is grounded in the is lm framework this comment utilizes the same framework to demonstrate that the amount of crowding out may be inversely related to the size of the interest rate change therefore cebula s claim that his evidence establishes a transmission mechanism for crowding out is unfounded indeed full crowding out in a simple is lm world is possible with or without increases in the interest rate at the other end of the spectrum zero crowding out can occur with or without increases in the interest rate a similar indeterminacy applies to partial crowding out scenarios the statistical significance of the relationship between deficits and the interest rate is irrelevant as far as the issue of a transmission mechanism for crowding out is concerned the appropriateness of cebula s econometric procedures is not the issue our contention is that it does not make any difference what the procedures show thus our comment applies with equal force to cebula s antagonists those who argue that a transmission mechanism does not exist because their empirical work shows no relationship between budgetary deficits and the interest rate

fly by night firms and the market for product reviews this paper presents a model that permits third party information provision in a market characterized by information asymmetries and reputation formation the model is used to examine how the market for information provision affects prices and supply in the primary market they find that decreasing the cost of providing and using information 1 increases rather than decreases the margins received by reputable service firms 2 decreases the price of new untested service firms so reputation is more costly to build and 3 leads to more high quality firms and less fly by night firms copyright 1989 by blackwell publishing ltd

revenue sharing in movie exhibition and the arrival of sound i introduction at least since adam smith economists have been intrigued by share contracts there has been a proliferation of models most of which tend to explain the share contract as resulting from some mix of optimal risk bearing and optimal effort motivation 1 a large number of researchers have attempted to test these models empirically sharecropping contracts not surprisingly are the most intensively examined the bibliography in knoeber 2000 but similar studies have been conducted in many other areas for example martin 1988 and lafontaine 1992 examine franchise arrangements hallagan 1978 investigates contracts used to lease gold claims leffler and rucker 1991 analyze a sample of private timber sale contracts goldberg and erickson 1987 study long term contracts for the sale of petroleum coke aggarwal and samwick 1999 investigate incentive contracts between firms and their executives and chisholm 1997 goldberg 1997 and weinstein 1998 all examine profit sharing contracts between fi lm companies and the talent this article differs in an important respect from most previous studies which analyze a cross section of contracts in an attempt to determine how or whether they vary according to the attributes of the contracting parties or the products being contracted for instead it investigates an area where a sudden technology shock led to the rapid and widespread replacement of one form of contracting by another the industry is the motion picture business and the shock was the arrival of sound during the silent film era the vast majority of first run feature films were rented to cinemas for flat daily or weekly payments within two years of the release of the first sound picture revenue sharing contracts were the norm and they remain the norm to this day 2 my goal is to investigate the degree to which the standard economic concerns moral hazard risk sharing and measurement problems can explain this change because the contracting parties remained the same the question becomes what was altered in the nature of the product or in its provision so as to have altered correspondingly the incentives faced i conclude the following first the advent of sound fundamentally changed the inputs live music and other acts supplied by the exhibitor and central to the show were replaced by a soundtrack and short sound films supplied by the film company the benefit of deterring exhibitor shirking through the use of flat rental fees which made the exhibitor full residual claimant declined accordingly the party whose effort makes the largest contribution to marginal product generally receives the largest proportion of the residual claims and in the decades following the arrival of sound the proportion of residual claims collected by film companies rose steadily in addition average revenue per film increased with sound whereas the cost of ensuring that exhibitors reported attendance revenue honestly done by locating a film company s representative in the theater remained the same the ex post division of revenue necessary for revenue sharing thus became cheaper on a per film basis finally uncertainty ab out the value in terms of expected attendance revenue of the early sound films appears to have raised the cost of negotiating lump sum rental fees and thus promoted experiments with revenue sharing however although this may have contributed initially it cannot explain the practice s persistence uncertainty about film values declined as talking films became better known ii the nature of the problem a film company contracts with an exhibitor so that they may jointly produce the final good a movie presentation 3 to that end each supplies essential inputs the film company provides the movie itself assembled from a variety of inputs and some sort of national advertising support the exhibitor provides the theater which consists of seating projection equipment a refreshment stand and other support activities and some form of local advertising

asymmetric information and overinvestment in quality in a standard adverse selection world asymmetric information about product quality leads to quality deterioration in the market suppose that a higher investment level makes the realization of high quality more likely then if consumers observe the investment but not the realization of product quality before purchase they can infer the probability distribution of high and low quality that may be put on the market we uncover two effects that may lead the firm to overinvest in quality compared to a market with full information first an adverse selection effect according to which a sufficiently large investment can avoid adverse selection and second an efficiency effect according to which a larger investment reduces the probability of having in the market low quality products that are not socially valuable

the antecedents and performance implications of cooperative exchange norms our study investigates the antecedents and performance implications of cooperative exchange norms we argue that in early relationships the level of expected cooperative norms in an exchange is the result of a calculative process facilitated by transaction attributes joint transaction specific investments and observability the greater the level of these two exchange attributes the greater the level of cooperative exchange norms all else being equal we further argue that the realized level of cooperative exchange norms can deviate from the expected level because the development of such norms is the result of social processes that management cannot directly and fully control this gap between realized and expected norms affects exchange performance performance suffers when the realized level of cooperative exchange norms falls below the expected level but overshooting expectations lays a critical groundwork for repeat transactions the analysis of a survey of 182 collaborative r d alliances provides initial support for our theory

ricardian equivalence and the public and private saving nexus in india abstractthis study tests the ricardian equivalence theorem ret and examines the responsiveness of private saving to public saving in india most estimators do not provide support for the empirical validity of ret and long run cointegration between public and private saving the increases in household saving hhs seem to have been engendered by the provision of saving incentives institution of saving schemes self driven motivation to save and the precautionary accumulations induced by uncovered uncertainties in incomes rather than by ricardian behaviour of households the self imposed aversion to debt and debt bequest borrowing and liquidity constraints and the intertemporal smoothing of consumption have been the added catalysts that contributed to the increases in hhs the households with binding borrowing constraints inadequate or no insurance and uncovered uncertainties in incomes seem to have been saving more to pay for higher inflation tax the fiscal consolidation and generation of public s

credit rating industry a helicopter tour of stylized facts and recent theories the recent subprime crisis and the ongoing euro zone crisis have generated an enormous interest in the credit rating industry not only among economists but also among average citizens as a consequence we have seen an explosion of the economic literature on the industry the objective of this survey is to introduce readers to the key stylized facts of the credit rating industry and to the recent theoretical economic literature on this industry

chapter 9 econometric and time series market response models publisher summary marketing has seen a rapid expansion in the widespread use of quantitative methods correlation and regression analysis were among the first techniques used as marketing research emerged as a discipline after world war ii in the early 1970s regression analysis became econometrics simultaneous equation systems could be estimated almost as easily as single regression equations while econometrics as a whole continues to flourish as new and more sophisticated estimation techniques and associated computer software have become available simultaneous equation systems have not become widely prevalent the dynamic structure of marketing variables themselves is addressed in the chapter followed by discussions of leads and lags among marketing variables and the assessment of the direction of causality dynamic properties of sales response functions have been discussed in more detail marketing generalizations that have been uncovered as well as empirical evidence on the shape of the sales response function is reported

does it pay to change your company s name a stock market perspective a company s name is commonly considered to be an integral part of its image just like the quality of its products or the quality of its technical services changing a company s name is a major policy decision contemplated by many firms and actually implemented by some each year this paper attempts to examine albeit indirectly whether a name change can improve the profit performance of a firm and what type of firm is more likely to succeed in doing so we use the event study methodology developed in finance to examine the above questions with respect to 58 corporations that changed their names in 1981 1985 our findings are that for most of the firms name changes are associated with improved performance and that the greatest improvement tends to occur in firms that produce industrial goods and whose performance prior to the change was relatively poor evidence that industrial good producers are also heavy users of corporate advertising lends further credence to this finding our findings do not support however the contention that the new name per se will enhance demand for the firm s products rather it seems that the act of a name change serves as a signal that other measures to improve performance such as changes in product offerings and organizational changes will be seriously and successfully undertaken the rationale behind why such a signal is sent and why it is believed is discussed

the reputational penalties for environmental violations empirical evidence abstract this paper examines the sizes of the fines damage awards remediation costs and market value losses imposed on companies that violate environmental regulations firms that violate environmental laws suffer statistically significant losses in the market value of firm equity the losses however are of similar magnitudes to the legal penalties imposed and in the cross section the market value loss is related to the size of the legal penalty thus environmental violations are disciplined largely through legal and regulatory penalties not through reputational penalties

product complementarities capabilities and governance a dynamic transaction cost perspective the organization and governance of the transactions that comprise a bundling arrangement depend on the distribution of capabilities among firms and the amount of time during which the window of opportunity for earning rents is expected to remain open firms engaged in inter firm collaboration must undertake support transactions related to billing marketing customer support and product repair these support transactions differ from the core transactions that have traditionally been perceived as sufficient to provide a product bundle since support transactions create costs of their own the market may turn out to be an expensive means of governing collaborative arrangements undertaken for bundling purposes the telecommunications service sector provides an illustration copyright 1997 by oxford university press

testing alternative econometric models on the existence of advertising threshold effect threshold effect of advertising has received wide attention in the marketing literature but little formal representation of this phenomenon has been developed on the basis of monthly time series

interest group competition and the organization of congress theory and evidence from financial services political action committees we develop a positive theory of how interest group competition shapes the organization of congress and use it to explain campaign contribution patterns in financial services since interest groups cannot enforce fee for service contracts with legislators legislators have an incentive to create specialized standing committees which foster repeated dealing between interests and committee members the resulting reputational equilibrium supports high contributions and high legislative effort for the interests contribution patterns by competing interests in the congressional battle over whether banks can enter new businesses support the theory which also has implications for term limits and campaign reform
