the distribution of money and prices in search equilibrium this article considers a search theoretic model of monetary exchange agents bargain over both the amount of money and the quantity of goods to be exchanged in bilateral meetings determining endogenously the distributions of money and of prices i show that money is neutral if changes in the money supply are accomplished via proportional transfers however within the class of lump sum transfers an increase of the rate of monetary expansion tends to decrease the dispersion of wealth and prices and to improve welfare when inflation is low but when inflation is high enough the opposite effects occur

fiscal policy with agents differing in altruism and ability this paper presents an overlapping generations model of growth with individuals differing in productivity and altruism within such a model wealth is entirely held in the steady state by the families with the highest degree of altruism we then look at the macroeconomic and distributive effects of three fiscal policies public debt pay as you go social security and estate taxation under plausible assumption we show that both public debt and social security are neutral a la ricardo but increase inequality we also show that a estate taxation can be pareto worsening even though it can foster income equality

tax perceptions and preferences over tax structure in the united kingdom do voters know their tax liabilities accurately or do they systematically misperceive them could such misperceptions influence voters choices over alternative tax structures proposed by politicians this paper assesses the accuracy of individuals tax perceptions in the uk using micro data from the british social attitudes survey 1995 and tests an empirical model of the determinants of tax structure preferences including tax misperceptions a systematic bias towards over estimation of income and expenditure tax vat liabilities is found and individ uals tax preferences appear to be both dominated by self interest and distorted by tax misperceptions whether using a traditional utility maximisation framework or a variety of public choice frameworks economists agree that consumer voters or taxpayer voters dislike taxes taxes lower the consumption possibility set and thereby utility politicians proposing higher taxes expect to lose votes unless they can persuade voters that the utility gain from the use of those taxes will exceed the tax induced utility loss of course the extent of individuals losses will depend on their circumstances and how revenues are raised the tax structure traditional tax incidence and excess burden analyses and models of political costs associated with the tax structure hettich and winer 1984 1988 each provide guidance on the extent to which different individuals may be expected to suffer and vote differently under alternative tax structures much will depend on attitudes towards and perceptions of specific taxes especially personal income taxes and consumption taxes underlying most such analyses are two common presumptions i tax preferences are dictated by self interest and ii individuals accurately assess their tax liabilities and so make informed choices two largely independent areas of literature have challenged these assumptions first models incorporating altruism

cyclical dynamics in idiosyncratic labor market risk is individual labor income more risky in recessions this is a difficult question to answer because existing panel data sets are so short to address this problem we develop a generalized method of moments estimator that conditions on the macroeconomic history that each member of the panel has experienced variation in the cross sectional variance between households with differing macroeconomic histories allows us to incorporate business cycle information dating back to 1930 even though our data do not begin until 1968 we implement this estimator using household level labor earnings data from the panel study of income dynamics we estimate that idiosyncratic risk is i highly persistent with an annual autocorrelation coefficient of 0 95 and ii strongly countercyclical with a conditional standard deviation that increases by 75 percent from 0 12 to 0 21 as the macroeconomy moves from peak to trough

liquidity redistribution and the welfare cost of inflation abstract the long run welfare costs of inflation are studied in a micro founded model with trading frictions and costly liquidity management by modelling the liquidity management decision the model endogenizes the responses of velocity output the degree of market segmentation and the distribution of money compared to the traditional estimates based on a representative agent model the welfare costs of inflation are significantly smaller due to distributional effects of inflation the welfare cost of increasing inflation from 0 to 10 is 0 62 of consumption for the us economy furthermore the welfare cost is generally non linear in the inflation rate

money holdings inflation and welfare in a competitive market this paper examines an environment where money is essential and agents exchange in perfectly competitive walrasian markets agents consume and produce a homogeneous good but hold money to purchase consumption in the event of a relatively low productivity shock a walrasian market delivers a non degenerate distribution of money holdings across agents and avoids some of the computational difficulties associated with the market and pricing assumptions of bilateral matching and bargaining common to search theoretic environments the model is calibrated to long run us velocity and the welfare costs of inflation are assessed for variable buyer seller ratios and persistent states of buying and selling

on inflation as a regressive consumption tax abstract evidence on the portfolio holdings and transaction patterns of households suggests that the burden of inflation is not evenly distributed we build a monetary growth model consistent with key features of cross sectional household data and use this framework to study the distributional impact of inflation at the aggregate level our model economy behaves similar to standard monetary growth models within the representative agent abstraction inflation has however important distributional effects since it is effectively a regressive consumption tax thus neglecting the distributional consequences of inflation may prove misleading in assessing the effects of inflation in our economy

financial sophistication and the distribution of the welfare cost of inflation abstract the welfare cost of anticipated inflation is quantified in a calibrated model of the u s economy that exhibits tractable equilibrium dispersion in wealth and earnings inflation does not generate large losses in societal welfare yet its impact varies noticeably across segments of society depending also on the financial sophistication of the economy if money is the only asset then inflation mostly hurts the wealthier and more productive agents while those poorer and less productive may even benefit from inflation the converse holds in a more sophisticated financial environment where agents can insure against consumption risk with assets other than money

borrowing costs and the demand for equity over the life cycle abstract we construct a life cycle model that delivers realistic behavior for both equity holdings and borrowing the key model ingredient is a wedge between the cost of borrowing and the risk free investment return borrowing can either raise or lower equity demand depending on the cost of borrowing a borrowing rate equal to the expected return on equity which we show roughly matches the data minimizes the demand for equity alternative models with no borrowing or limited borrowing at the risk free rate cannot simultaneously fit empirical evidence on borrowing and equity holdings

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

optimal monetary policy in an economy with incomplete markets and idiosyncratic risk abstract this study investigates an incomplete markets economy in which the saving behavior of a continuum of infinitely lived agents is influenced by precautionary saving motives and borrowing constraints agents can use two types of assets interest bearing ious and money to smooth consumption money is valued because of a timing friction in the bond market in particular the bond market closes before agents observe their idiosyncratic productivity shock i find that the friedman rule is not optimal for this economy the results indicate that the optimal allocation has a rate of inflation of 10 and a positive amount of private credit held by the government a positive inflation rate transfers resources from agents with big endowments to those holding bonds which improves risk sharing and therefore welfare however for higher rates of inflation agents economize on money holdings offsetting the insurance effects and causing a reduction in welfare furthermore higher rates of inflation discourage agents from borrowing and the endogenous lower bound on bond holdings is higher than the exogenous borrowing limit high rates of inflation therefore exacerbate frictions in the bond market

can mergers increase output evidence from the lodging industry we find that hotel mergers increase occupancy in some specifications price also rises because these effects occur only in markets with high capacity utilization and high uncertainty we reject simple models of price or quantity competition in favor of models of revenue management where firms price to fill available capacity in the face of uncertain demand

the timing of intergenerational transfers tax policy and aggregate savings the authors analyze an overlapping generations framework that accommodates two observations 1 the interest rate on consumption loans exceeds the rate of return to savings and 2 private intergenerational transfers primarily occur early in the life cycle assuming altruistically motivated transfers in at least some family lines and other plausible conditions the authors prove the invariance of capital s steady state marginal product to government debt government expenditures and the tax rates on labor and capital income the authors show that the tax treatment of household interest payments has powerful effects on capital intensity and aggregate savings in life cycle and especially altruistic linkage models copyright 1992 by american economic association

labor supply elasticity and social security reform abstract previous literature on social security reform has used a variety of period utility functions and calibrated values for the intertemporal elasticity of substitution ies in labor in this paper we show that the effects of social security reforms on aggregate labor supply are invariant to plausible values of the ies but the effect of such reforms on the profile of hours over the life cycle is highly sensitive to the ies we first establish these results analytically in a simple partial equilibrium setting and then demonstrate their robustness in a general equilibrium model calibrated to match key u s macroeconomic indicators we find that the aggregate effects are similar regardless of the wide range of the values of ies used in calibrated economies however social security reform leads to a large reallocation of hours worked over the life cycle from early years to later working years and the size of this reallocation significantly increases with the ies

the welfare cost of inflation under imperfect insurance abstract this paper examines the welfare cost of inflation in an economy where agents hold money in order to smooth consumption in the face of income variability for which there is no insurance the findings indicate that for the type of economies considered here the area under the empirical money demand curve is a poor measure of the welfare cost of inflation this area accounts for only one fourth of the true costs in the case of 5 inflation

preferences inflation and welfare abstract this paper systematically examines how degrees of household risk aversion ra and elasticity of intertemporal substitution eis impact the welfare costs of inflation in a heterogeneous agent environment featuring capital and essential money empirical evidence suggests that households have degrees of ra and eis that differ on average from traditional values and display large amounts of dispersion capturing these empirical features of preference values in an otherwise standard model leads to welfare enhancements of inflation due to household substitution of money for capital the analysis also compares the welfare implications for alternative ways to implement monetary policy

monetary and fiscal policies in a heterogeneous agent economy i study the effects of long run inflation and income taxation in an economy where households face uninsurable idiosyncratic risks i construct a tractable competitive search framework that generates dispersion of prices income and wealth i analytically characterize the stationary equilibrium and the policy effects on individual choices quantitative analysis finds that monetary and fiscal policies have distinctive effects on macro aggregates such as output savings wealth dispersion income and consumption inequalities there can be a hump shape relationship between welfare and the respective policies overall welfare can be maximized by a deviation from the friedman rule paired with distortionary income taxation

contestable markets and the theory of industry structure a review article contestable markets and the theory of industry structure is a comprehensive integration expansion and application of the ideas of william j baumol elizabeth e bailey john c panzar robert d willig edward zajac and their associates on contestability theory in 16 chapters baumol panzar and willig 1982a try to make precise especially in a multiproduct context ideas related to the chicago school approach to industrial organization to argue forcefully that potential entry disciplines monopoly and at the same time to offer a product more directly useful to the policymaker than the more abstract mathematical writings on increasing returns there are at least five basic ideas presented here first under certain structural conditions on technology and certain technical requirements on demands frictionless entry and exit together with equal access to technology lead to a type of competitive equilibrium with desirable welfare consequences even though there may be only one active firm in equilibrium a market with the foregoing characteristics of frictionless reversible entry and equal access to technology is called a perfectly contestable market by baumol et al 1982a the market for air travel between two cities serves as a canonical example such a market may support only one airline but the active airline must price at cost to prevent a price cutting rival airline from flying in and skimming off customers the authors conclude that the presence of such shadow entrants will force competition like behavior by the incumbent even though the market may be a natural monopoly second baumol et al 1982a define natural monopoly as a situation where the technology is characterized by a subadditive cost function that is to say c l7 yt l c y for any collection of output

parental altruism and inter vivos transfers theory and evidence this paper uses psid data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism specifically the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child s income results in the parents increasing their transfer to the child by one dollar this restriction on parental and child transfer income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints these additional elements pin down the timing of inter vivos transfers the method used to estimate income transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism the findings strongly reject the altruism hypothesis redistributing one dollar from a recipient child to donor parents leads to less than a 13 cent increase in the parents transfer to the child far less than the one dollar increas

contestable markets and the theory of industry structure alreview articleo phe new book by william j baumol john c panzar and robert d willig is the culmination of several years of research on the related problems of understanding multiproduct cost structures and their implications for competition and market performance it is a significant book for several reasons the empirical reality that forms the starting point for the theoretical work is i think widely recognized to be important cost structures constitute one of the foundations of competitive strategy and strongly influence industry structure notwithstanding this fact the amount of microeconomic theory directed toward competitively relevant attributes of costs has been if not minimal then certainly more limited than the subject deserves in fact prior to the work of our authors economists and business strategists did not have a language or a set of concepts with which to talk precisely about scale economies in a multiproduct setting we now have at least the beginnings of such a language and a body of theory that provides a grammar for using it the theory of contestable markets was the subject of baumol s presidential address at the american economic association meetings in washington in december 1981 both the theory and its presentation have generated controversy useful controversy i think because it helps clarify issues that need attention i shall have remarks to offer later in this review concerning the normative and descriptive relevance of the contestable markets hypothesis my plan for this review is as follows i begin by outlining some of the principal definitions and propositions of the theory this outline should not be mistaken for a complete summary of the book but the economist who has not yet read the book needs a reasonably detailed picture of the approach few of the propositions require long proofs in fact once they are stated the proofs are often simple exercises having outlined some of the principal concepts i comment upon their usefulness for understanding markets and finally i conclude by suggesting some ways in which the general subject may be pursued from this point forward

quantitative asset pricing implications of endogenous solvency constraints we study the asset pricing implications of an economy where solvency constraints are endogenously determined to deter agents from defaulting while allowing as much risk sharing as possible we solve analytically for efficient allocations and for the corresponding asset prices portfolio holdings and solvency constraints for a simple example then we calibrate a more general model to u s aggregate as well as idiosyncratic income processes we find equity premia risk premia for long term bonds and sharpe ratios of magnitudes similar to the u s data for low risk aversion and a low time discount factor article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

understanding the distributional impact of long run inflation the impact of fully anticipated inflation is systematically studied in heterogeneous agent economies with an endogenous labor supply and portfolio choices in stationary equilibrium inflation nonlinearly alters the endogenous distributions of income wealth and consumption small departures from zero inflation have the strongest impact three features determine how inflation impacts distributions and welfare financial structure shock persistence and labor supply elasticity when agents can self insure only with money inflation reduces wealth inequality but may raise consumption inequality otherwise inflation reduces consumption inequality but may raise wealth inequality given persistent shocks and an inelastic labor supply inflation may raise average welfare

asset salvageability and the potential for trade restraint through merger this article evaluates impact of asset salvageability on the profitability of restraint of trade through industrial combination in the case of merger either for monopoly or market dominance a postmerger price equal to the premerger competitive price is proved a reasonable possibility even in a declining industry where noncompetitive pricing is unlikely to attract new firms raising prices after merger may prove suboptimal in cases where a postmerger price increase is optimal asset salvageability is shown to have a restraining effect on the magnitude of the increase
