financial development income inequality and the redistributive effects of monetary policy abstract how should financial systems be designed to limit income inequality does the redistributive impact of inflation depend on the extent of financial development should optimal monetary policy vary across countries with different levels of financial development in order to address these questions we develop a monetary growth production model with heterogeneous agents in our economy optimal policy needs to weigh the effects of policy across two groups capital owners and individuals who hold liquid assets in this environment we compare various economies that are identical in every aspect except for their level of financial development interestingly we generally find that economies at the highest stages of financial development economies in which money bonds and claims to capital are traded experience the highest amount of capital formation and social welfare as long as inflation is low yet regardless of the extent of financial development there are generally redistributive consequences from inflation moreover the model tends to predict that economies with relatively small stock markets produce the highest levels of income inequality empirical work examining the role of money growth and the implications of financial development across countries is consistent with predictions from the model

transactions costs and the optimal quantity of money this paper models a physical environment in which agents rationally choose to hold both fiat money and higher return capital this occurs because information barriers permit bona fide capital to be distinguished from bogus titles to capital and bogus ious only at a cost one implication is that the holding period for capital is greater than that for fiat money the information barriers also limit the government interventions that are feasible and in so doing overturn standard notions concerning the optimal quantity of money in this paper i model a physical environment in which agents rationally choose to hold both fiat money and a productive asset with a greater rate of return moreover the fiat money in this model circulates with a greater velocity than does the productive asset in this model agents live 3 period lives and are members of generations that overlap they receive an endowment of the model s single consumption good only in the first period of life and must therefore hold assets to provide for consumption in other periods of life when the consumption good is stored it only yields a return 2 periods after it was stored as a result storage can be used to provide for consumption in the third period of life the crucial assumptions of the model are restrictions on the infor

a growth model of inflation tax evasion and financial repression abstract this paper studies the relation between policies of financial repression inflation rates and long term growth we set up a model which shows that governments might want to express the financial sector because this sector is an easy source of resources for the public budget the inflation tax to the extent that the financial sector increases the efficiency of the allocation of savings to productive investment the choice of the degree of financial development will have real effects on the growth rate of the economy in countries where tax evasion is large the government will optimally choose to repress the financial sector in order to increase seigniorage taxation this policy will then reduce the efficiency of the financial sector increase the costs of intermediation reduce the amount of investment and reduce the growth rate of the economy financial repression will therefore be associated with high tax evasion low growth and high inflation

optimality of the friedman rule in an overlapping generations model with spatial separation recent models with spatial separation and limited communication suggest that the friedman rule may not be optimal this is important in light of the disparity between theory and practice concerning optimal monetary policy we take a close look at these models and show that intergenerational transfers are key to the suboptimality of the friedman rule the friedman rule is a necessary condition for achieving the efficient allocation in equilibrium we also show that the friedman rule is chosen whenever agents can implement mutually beneficial arrangements

why does overnight liquidity cost more than intraday liquidity abstract in this paper we argue that the observed difference in the cost of intraday and overnight liquidity is part of an optimal payments system design in our environment overnight liquidity affects output while intraday liquidity affects only the distribution of resources between money holders and non money holders the low cost of intraday liquidity is explained by the friedman rule the optimal cost differential achieves the twin objective of reducing the incentive to overuse money at night and encouraging payment risk sharing during the day

intergenerational altruism dynastic equilibria and social welfare are three central findings first under relatively weak conditions welfare optima cannot be implemented as dynastic equilibria with positive levels of transfers second intergenerational altruism ordinarily renders the objectives of social planners dynamically inconsistent thereby making implementation of welfare optima problematic third if a planner successfully resolves dynamic inconsistency by committing himself to respect the preferences of deceased generations and if there are a sufficient number of prior generations then in a specific set of cases dynastic equilibria are approximately welfare optimal

money and credit in liquidity provision abstract this paper studies the liquidity provision in a model where the roles of money are challenged by other financial instruments alternative to money credit can be used as means of payment and rate dominating assets are available to serve as stores of value two features are found to be crucial in rendering money valuable in this environment information asymmetry in credit trading relationship and uncertainty in individuals liquidity demand in general the model economy can display a payment mechanism of money only credit only or mixed use of money and credit in transactions depending on the severity of the information asymmetry the optimal quantity of money in our paper is shown to contrast those in other monetary models

welfare impact of a ban on child labor i introduction the issue of child labor has recently been the subject of a surge in formal economic analysis according to the international labor organization 2006 there has been a significant decrease in child labor and an even steeper decline in hazardous child labor nevertheless in 2004 there were still 218 million child laborers of whom 126 million were in hazardous work the increase in research around this topic is in part the result of the growing awareness of the persistence of child labor around the world and the importance of developing theoretical models that help us understand the incidence of child labor and its implications as only then can we recommend and implement effective policy interventions the economics literature is ambiguous on the desirability of a ban on child labor child labor is typically viewed as the result of some deeper problem in the economy and addressing child labor without solving the problem that leads to its occurrence can make children worse off for example dessy and pallage 2005 present an environment where although child labor has a negative direct impact on children s well being it is the best available choice for children hence a ban on child labor even on its worst forms deprives children of their best possible choice and can make children worse off standard arguments for the imposition of restrictions on child labor are based on the existence of externalities such as positive externalities from a well educated population see udry 2006 a ban on child labor leads children to allocate more resources to education brings the average levels of human capital closer to the optimal and consequently increases welfare constraining the amount of labor supplied by children is also often suggested as an instrument to move the economy toward a desired equilibrium in environments where multiple equilibria can emerge as in dessy and pallage 2001 and basu and van 1998 banning child labor can also be an instrument to achieve increases in efficiency in the presence of capital market imperfections in baland and robinson 2000 capital market imperfections do not allow altruistic parents to internalize the negative impact of child labor on children s human capital accumulation a restriction on the amount of time allocated to work by children is suggested to reduce the resulting inefficiently high levels of child labor finally rogers and swinnerton 2002 advance parents incomplete information on the type of work safe or hazardous their children perform as an argument for a ban on the worst forms of child labor 1 in this article i show that in a standard overlapping generations economy with parental altruism calibrated to the 1880s a ban on child labor increases parental transfers and raises children s as well as the average levels of welfare in the short run and in the long run this result introduces a new rationale for imposing restric ons on child labor adding to a debate still in its early stages of development 2 in an overlapping generations economy with altruism the unconstrained nash cournot equilibrium does not maximize the average welfare of currently living agents as was shown in bernheim 1989 nor the welfare of children and generates suboptimal levels of parental transfers by reducing the income earned by children a ban on child labor reduces children s consumption raising their marginal utility of consumption and parents respond by increasing transfers to children hence the ban places children at a point in their parents reaction function that results in a higher level of parental transfers by inducing an increase in parental transfers the ban on child labor moves the economy closer to the social optimal generating aggregate welfare gains children are made better off because they receive more transfers and do not work parents are made worse off because they need to decrease consumption and leisure to increase parental transfers however the raise in their children s lifetime utility partially offsets this effect

heterogeneity redistribution and the friedman rule we study monetary models with nondegenerate stationary distributions of money holdings we find that the friedman rule does not typically maximize ex post social welfare an increase in the rate of growth of the money supply has two effects the standard distortionary or rate of return effect makes money a less desirable asset for all moneyholders a second redistributive effect creates a transfer from one type of agent to the other an increase in the rate of growth of money away from the friedman rule can produce a rate of return effect that dominates the standard effect

oil shocks and oil stocks evidence from the 1970s the present paper examines the returns to 29 oil companies listed on the new york stock exchange during the period surrounding the oil shock of 1973 the returns are decomposed into production refining foreign and domestic operations the hypothesis that domestic price controls benefitted refiners is tested finally the hypothesis that oil price risk was priced in the sense of the arbitrage pricing theory is tested

a theory of intergenerational altruism modeling intergenerational altruism is crucial to evaluate the long term consequences of current decisions and requires a set of principles guiding such altruism we axiomatically develop a theory of pure direct altruism altruism is pure if it concerns the total utility rather than the mere consumption utility of future generations and direct if it directly incorporates the utility of all future generations our axioms deliver a new class of altruistic forward looking preferences whose weight put on the consumption of a future generation generally depends on the consumption of other generations the only preferences lacking this dependence correspond to the quasi hyperbolic discounting model which our theory characterizes our approach provides a framework to analyze welfare in the presence of altruistic preferences and addresses technical challenges stemming from the interdependent nature of such preferences

the strategic bequest motive although recent research suggests that intergenerational transfers play an important role in aggregate capital accumulation our understanding of bequest motives remains incomplete we develop a simple model of strategic bequests in which a testator influences the decisions of his beneficiaries by holding wealth in bequeathable forms and by conditioning the division of bequests on the beneficiaries actions the model generates falsifiable empirical predictions that are inconsistent with other theories of intergenerational transfers we present econometric and other evidence that strongly suggests that bequests are often used as compensation for services rendered by beneficiaries

friedman rule in a model with endogenous growth and cash in advance constraint this paper introduces money into an overlapping generations model with endogenous growth the model due to docquier et al 2007 exhibits a positive intergenerational externality which precludes its laissez fair equilibrium to be optimal even if the government can control the level of physical capital and set it to satisfy the modified golden rule the main message of the paper is that as long as the modified golden rule is attained friedman rule is optimal the result holds regardless of the ability of the government to internalize the externality and control the level of human capital other results include i violation of friedman rule for a different second best environment wherein human capital accumulation is controlled but not physical capital accumulation ii existence of a negative relationship between money growth rate and the economy s endogenous growth rate and iii non uniqueness of friedman rule

endogenous market participation and the general equilibrium value of money we study the monetary theory implications of fixed costs associated with trade in private assets we show that with heterogeneous endowment profiles it is possible for an endogenous subset of agents to hold currency even when it is dominated in return by a competing asset with respect to positive issues in monetary theory the model implies that changes in the steady state growth rate of the money supply have a negative effect on real interest rates because of endogenous market participation measures on the normative side we show that there may be an equity efficiency trade off from monetary deflation

climate change and intergenerational equity revisiting the uniform taxation principle on carbon energy inputs abstract this paper presents a neoclassical growth model with three energy sectors and a climate externality energy is used in the production of the final consumption good the energy sectors differ on the exhaustibility of the energy resource oil is an exhaustible resource coal is an abundant resource and a green energy sector uses labor oil and coal use increases the stock of carbon in the atmosphere which generates a climate externality standard pigouvian taxation prescribes that a uniform tax on all carbon energy inputs is optimal this uniform tax must be equal to the social cost of carbon because this is the externality that the usage of these inputs generates i consider a policymaker who cares about future generations and may discount the future less than the individuals in the economy this paper s main theoretical result is that the uniform taxation rule does not carry over to an economy with a low social discount rate in particular the optimal carbon tax on oil does not equal the optimal carbon tax on coal moreover while the optimal tax on coal equals the social cost of carbon the optimal carbon tax on oil follows a more general formula

carbon pricing carbon sequestration and social discounting abstract this paper studies the optimal taxation of carbon emissions in a dynastic economy when the welfare function places direct pareto weights on unborn generations the social discount rate is lower than the discount rate of the current generation i show that this welfare criterion has important consequences for the structure of the optimal regulatory system in particular i show that i the optimal carbon tax does not in general equal the social cost of carbon ii a subsidy on oil reserves is sometimes optimal and iii carbon trading programs should limit the award of carbon offset allowances

a nominal theory of the nominal rate of interest and the price level this paper develops a simple theory of nominal income and interest determination under the assumption that the only relevant distinction between money and bonds lies in their holding periods individuals take full account of the government budget constraint and do not concern themselves with discounting future tax liabilities associated with the issue of government bonds according to this theory the price of bonds is analogous to the price level and the nominal rate of interest is determined by the bond money ratio and bears no close relationship to the rate of expansion of the price level

on the coexistence of money and higher return assets and its social role this paper adopts mechanism design to investigate the coexistence of at money and higherreturn assets we consider an economy with pairwise meetings where at money and riskfree capital compete as means of payment as in lagos and rocheteau 2008 the trading mechanism in pairwise meetings is chosen among all individually rational renegotiation proof mechanisms to maximize society s welfare we show that in any stationary monetary equilibrium capital commands a higher rate of return than at money

long run neutrality high inflation and bank insolvencies in argentina and brazil abstract using long low frequency data on money and output over 1884 1996 for argentina and over 1912 1995 for brazil it is found that money is long run neutral but not long run superneutral with regard to real output a rise in money growth is associated with a decline in output the opposite of the tobin effect the introduction of dummy variables for 1930s or to capture recent periods of financial disruption associated with bank insolvencies does not restore long run superneutrality for either country however results indicate that bank insolvency episodes have a distinct and negative influence on output

wealth distribution inflation tax and societal benefits of illiquid bonds illiquid nominal government bonds are shown to have two opposing effects on welfare first the relatively poor choose to top up money balances for future consumption by purchasing nominal bonds at a discount the wealth distribution becomes more centered with a smaller consumption deviation from the first best second the higher inflation tax on monetary wealth to finance interest payments makes money less valuable so that the quantity of output produced in exchange for money decreases the trade off between the welfare enhancing effect on wealth distribution and the distortionary effect on output implies the socially optimal discount rate and liquidity

intergenerational disagreement and optimal taxation of parental transfers we study optimal taxation of bequests and inter vivos transfers in a model where altruistic parents and their offspring disagree on intertemporal trade offs we show that the laissez faire equilibrium is pareto inefficient and whenever offspring are impatient from their parents perspective optimal policy involves a positive tax on parental transfers cautioned by the technical complications present in this class of models our normative prescriptions do not rely on the assumption of differentiability of the agents policy functions

the optimum quantity of money rule in the theory of public finance this paper examines optimal tax policy in a monetary economy in which money serves as an intermediate good that helps facilitate the conversion of scarce resources into tinal consumption goods by enabling consumers to economize on the costs of transacting it is shown that in such an environment even though distorting taxes must be levied for revenue purposes the optimal tax structure calls for abstaining from inflationary finance and adopting the optimum quantity of money rule

beyond gdp an overview of measurement issues in redefining wealth in the last decades a growing quantity of literature has been written about concepts such as quality of life and well being as a proxy for evaluating societal prosperity and progress this paper analyses the theoretical foundations and the empirical validity of multi dimensional technical tools that can be used for well being measurement there is no doubt that there is a lot of complexity and fuzziness inherent in multi dimensional concepts such as well being a possible reduction of this complexity a pre condition for policy making introduces the problem of the descriptors used indicators and indexes in a multi dimensional framework multi criteria evaluation is a consistent approach for the construction of so called composite indicators often some individual indicators improve while others deteriorate this is the classical conflictual situation dealt with in multi criteria evaluation in particular non compensatory methods are quite relevant since compensability implies complete substitutability between different types of capital uncertainty and sensitivity analysis can estimate the robustness of the results obtained and help the framing of the debate around the conceptual framework used that is which representation of reality and thus which societal values and interests has been considered

money and asset prices with uninsurable risks abstract we present a theory of differences of liquidity across assets based on an endogenous ranking of assets as media of exchange arising from their relative quality as hedging devices when assets have two distinct roles as intertemporal media of exchange and hedging devices buyers have generically a strict preference for paying sellers with the asset which is the relative better hedging device for sellers the consequence of this preference is that there are three monetary policy regimes and these regimes differ in which assets serve as media of exchange whether assets carry a liquidity premium and in the impact that monetary policy has on asset prices

optimal monetary policy and economic growth abstract a question at the center of many analyses of optimal monetary policy is why do central banks never implement the friedman rule to the list of answers to this question we add neoclassical production specifically the tobin effect as one possible explanation to that end we study an overlapping generations economy with capital where limited communication and stochastic relocation create an endogenous transactions role for fiat money we assume a production function with a knowledge externality romer style that nests economies with endogenous growth ak form and those with no long run growth the diamond model the tobin effect is shown to be always operative under crra preferences a mild degree of social increasing returns is sufficient but not necessary for some positive inflation to dominate zero inflation and for the friedman rule to be sub optimal irrespective of the degree of risk aversion

on functions quality and timeliness of economic information economic decisions confront more uncertainty as they grow in scope and reach further into the future they are likely to do so increasingly in decentralized economies that expand and diversify the economic incentives to reduce uncertainty and improve predictions and decisions give rise to the demand for large amounts of diverse information this is not a new phenomenon of course but it is revealed more clearly than ever in the present era of great advances in informational technology for now the demand is to a large extent visibly satisfied the knowledge industries or services of inquiring comthe uncertainty about economic information increases with the probability of error in the underlying data and their processing and interpretation many errors cannot be promptly detected and eliminated but can be gradually reduced over time as attested by the revisions in economic statistics this paper presents substantial evidence on the accuracy of provisional estimates of quarterly and monthly changes in 18 important variables measures of several aspects of data quality and of average lags of data release and signal detection are provided for a collection of 110 widely used economic indicators these materials help identify the location of the more serious measurement errors by variables and period and they show that informational lags of 5 and more months are frequent this paper is part of the national bureau of economic research program on economic fluctuations it was presented at the first international symposium on forecasting in quebec city on may 27 1981 and at the ifo institute for economics research in munich on september 23 1981 financial support from the national science foundation and the aid of the graduate school of business of the university of chicago and nber are gratefully acknowledged i am indebted to louis lambros for helpful suggestions and efficient research and to john gould and geoffrey moore for useful comments 1 growth in the modem economy is motivated by the desire to accumulate human and physical resources capital in the most general sense and is accomplished by actions that necessarily have long term consequences the decisions to choose these particular courses of action strategies must therefore be based on similarly long expectations which are fallible as the risk is high so is the premium on any knowledge that might help the decision maker

predicting u s recessions financial variables as leading indicators this paper examines the out of sample performance of various financial variables as predictors of u s recessions series such as interest rates and spreads stock prices and monetary aggregates are evaluated individually and in comparison with other financial and nonfinancial indicators the analysis focuses on out of sample performance from one to eight quarters ahead results show that stock prices are useful with one to three quarter horizons as are some well known macroeconomic indicators beyond one quarter however the slope of the yield curve emerges as the clear individual choice and typically performs better by itself out of sample than in conjunction with other variables

monetary policy rules based on real time data this paper examines the magnitude of informational problems associated with the implementation and interpretation of simple monetary policy rules using taylor s rule as an example i demonstrate that real time policy recommendations differ considerably from those obtained with ex post revised data further estimated policy reaction functions based on ex post revised data provide misleading descriptions of historical policy and obscure the behavior suggested by information available to the federal reserve in real time these results indicate that reliance on the information actually available to policy makers in real time is essential for the analysis of monetary policy rules

is the friedman rule optimal when money is an intermediate good in contrast to the recent literature on the optimal inflation tax we show that in models where money reduces transactions costs it is optimal to set the inflation tax to zero when seigniorage is replaced by revenue from distortionary taxes the main reasons for this result are that the variable costs of supplying real balances are negligible and the inflation tax is a unit tax we also show that the intermediate good optimal taxation rules in the public finance literature cannot be directly applied both when money is costless and when it requires resources to be produced

economic organization with limited communication this paper presents formal stylized representations of communication accounting systems oral assignment portable object written message and telecommunication systems are considered the environments that allow this formalization are characterized by spatial separation private information and a need to keep track of past actions transfers and shocks in environments that have spatial separation and private information beneficial multilateral arrangements can depend critically on agents ability to communicate to one another values of contemporary shocks and to keep track of histories of past transfers or past announced shocks this paper formalizes this idea and focuses on com

financial intermediaries markets and growth we build a model in which financial intermediaries provide insurance to households against idiosyncratic liquidity shocks households can invest in financial markets directly if they pay a cost in equilibrium the ability of intermediaries to share risk is constrained by the market from a growth perspective this can be beneficial because intermediaries invest less in the productive technology when they provide more risk sharing our model predicts that bank oriented economies can grow more slowly than more market oriented economies which is consistent with some recent empirical evidence

money banking and capital formation we consider a monetary growth model in which banks arise to provide liquidity in addition there is a government that issues not only money but interest bearing bonds these bonds compete with capital in private portfolios when the government fixes a constant growth rate for the money stock we show that there can exist multiple nontrivial monetary steady states one of these steady states is a saddle while the other can be a sink moreover paths approaching a steady state can display damped endogenous fluctuations and development trap phenomena are common across different steady states low capital stocks are associated with high nominal interest rates the latter signal the comparative inefficiency of the financial system also increases in the steady state inflation rate can easily reduce the steady state capital stock journal of economic literatureclassification numbers e13 e44 e50 g20 o16

resolving differences over the optimal quantity of money optimal steady state monetary policy in models of infinitely lived agents calls for a deflation of the fiat money stock at a rate that equates the rates of return of fiat money and capital this prescription for the optimal quantity of money holds whether the demand for money springs from placing money in the utility function friedman 1969 a cash in advance constraint grandmont and younes 1973 or spatial separation townsend 1980 in contrast monetary models of overlapping generations have counseled the golden rule optimality of a fixed stock of fiat money 1 this model has often been criticized for its lack of a transactions role for money that would distinguish itself from other assets 2 the seeming difference in this model s implications concerning the optimal quantity of money thus raises an obvious question 3 does the overlapping generations model obtain different welfare implications because it assumes a finite lifespan or because it lacks a special transactions role for money recent work has reexamined the optimal quantity of money in overlappinggenerations models featuring transactions roles for money abel 1987 who takes the broadest and clearest look finds that the golden rule optimal monetary policy

monetary policy banking crises and the friedman rule banking crises are frequent events gerard caprio and daniela klingebiel 1997 catalog over 80 banking crises during the last 25 years interestingly some banking crises are associated with no output losses whatsoever while others involve massive recessions finally it is known that the probability of a banking crisis rises as the rate of inflation rises see asli demirguc kunt and enrica detragiache 1997 john boyd et al 2001a b while received wisdom exists about the conduct of monetary policy while a crisis is underway there is no formal treatment of how the conduct of monetary policy during normal times affects the potential for banking crises to occur to fill that gap i consider economies where spatial separation and limited communication create a transactions role for money and random shocks to agents liquidity preferences create a role for banks in addition banks confront randomness in withdrawal demand when withdrawal demand is sufficiently high banks exhaust their cash reserves there are good reasons to associate this with a banking panic the output lost during a banking panic depends on how great withdrawal demand is some banking crises generate no output losses while others generate large reductions in resource availability in addition the conduct of monetary policy during normal times affects the probability of a banking crisis the higher the nominal interest rate the inflation rate the higher is the probability of a panic driving the nominal interest rate to zero following the friedman rule eliminates bank panics this constitutes a new rationale for the friedman rule nonetheless conventional methods of implementing the friedman rule never produce an optimal resource allocation in particular low nominal interest rates induce banks to hold large cash reserves thereby forgoing socially more productive investments in effect the friedman rule induces banks to become narrow banks voluntarily the banking system is very safe but it undertakes a suboptimal level of investment less conventional methods for implementing the friedman rule such as allowing unrestricted access to the discount window at a zero nominal interest rate lead either to the nonexistence of equilibrium or to massive indeterminacies none of the equilibria will be consistent with full optimality

the world distribution of income falling poverty and convergence period we estimate the world distribution of income by integrating individual income distributions for 138 countries between 1970 and 2000 country distributions are constructed by combining national accounts gdp per capita to anchor the mean with survey data to pin down the dispersion poverty rates and head counts are reported for four specific poverty lines rates in 2000 were between one third and one half of what they were in 1970 for all four lines there were between 250 and 500 million fewer poor in 2000 than in 1970 we estimate eight indexes of income inequality implied by our world distribution of income all of them show reductions in global inequality during the 1980s and 1990s

the optimal quantity of money a reconciliation abstract despite the apparent disagreement of samuelson s 1958 overlapping generations model and townsend s 1980 turnpike model on the optimal quantity of money in both i those endowed at the start with goods prefer a constant money stock and ii those endowed at the start with fiat money prefer deflation

be careful what you calibrate for social discounting in general equilibrium abstract concerns about intergenerational equity have led to an influential practice of setting social utility discount rates based on ethical considerations rather than to match household behavior particularly in climate change economics e g stern 2006 this paper formalizes the broader policy implications of this approach in general equilibrium by characterizing jointly optimal environmental and fiscal policies in a climate economy model with differential planner household discounting first i show that decentralizing the optimal allocation requires not only high carbon prices but also fundamental changes to tax policy if the government discounts the future less than households implementing the optimal allocation requires an effective capital income subsidy a negative intertemporal wedge and in a setting with distortionary taxation an effective labor consumption tax wedge that is decreasing over time second if the government cannot subsidize capital income the constrained optimal carbon tax may be up to 50 below the present value of marginal damages the social cost of carbon due to the general equilibrium effects of climate policy on household savings third given the choice to optimize either carbon capital or labor income taxes the socially discounting planner s welfare ranking is ambiguous over a standard range of parameters overall in general equilibrium a policy maker s choice to adopt differential social discounting may thus overturn conventional recommendations for both environmental and fiscal policy

the role of money in two alternative models when is the friedman rule optimal and why abstract in models of money with an infinitely lived representative agent ilra models the optimal monetary policy is almost always the friedman rule in overlapping generations og models by contrast the friedman rule may not be optimal in this paper we use this difference in monetary policy prescriptions to help us identify and study the key difference between these two models as models of money we study the welfare properties of monetary policy in a simple og model under two very different money demand specifications and two alternative assumptions about the generational timing of taxes for money retirement we conclude that the key difference between ilra and og monetary models is that in the latter the standard method for constructing a monetary regime causes transactions involving money to become intergenerational transfers under alternative government fiscal monetary regimes that offset these intergenerational transfers the friedman rule is always optimal

policy watch death watch for the estate tax the idea of making death a taxable event infuriates some people winston churchill called estate taxes an attempt to tax dead people rather than the living steve forbes campaigned in favor of no taxation without respiration bruce bartlett 1997 points out that a key plank in the communist manifesto was the abolition of inheritance rights opponents deride the death tax as inefficient inequitable and complex violating every norm of good tax policy supporters counter that the criticisms are overstated or wrong and argue that a highly progressive tax that patches loopholes helps provide equality of opportunity breaks up concentrations of wealth and encourages charitable giving can t be all bad these debates raise a number of research questions for economists in policy circles the death watch for the u s estate and gift tax is on in 1999 in a vote split almost completely along partisan lines the republican majority in

intergenerational altruism with future bias abstract we show that standard preferences of altruistic overlapping generations exhibit future bias which involves preference reversals associated with increasing impatience this underlies a conflict of interest between successive generations we explore the implications of this conflict for intergenerational redistribution when there is a sequence of utilitarian governments representing living generations and choosing policies independently over time we argue that future bias creates incentives to legislate and sustain a pay as you go pension system which every government views as a self enforcing commitment mechanism to increase future old age transfers

the real time predictive content of money for output abstract data on monetary aggregates are subject to periodic redefinitions presumably in part to improve their link to measures of output money data are also revised on a regular basis taking these data imperfections into account we reassess the evidence on the marginal predictive content of m1 and m2 for real and nominal output in particular first by using the latest version of the data that is available and then using sequences of historical time series that would have been available to forecasters in real time we are able to provide a comprehensive assessment of whether money is useful for predicting output we conclude that the generally significant marginal predictive content of m1 or m2 for output that is found using a recently revised data set is not duplicated in a real time setting although m2 is shown to remain useful when 1 year ahead forecasts are constructed using fitted vector autoregressive models

pairwise trade and coexistence of money and higher return assets abstract a new theory of coexistence of money and higher return assets is set out it applies to any setting in which some trade involves an exchange of goods for assets and occurs between two people a buyer and a seller we show that there exists a function mapping the portfolios of the buyer and the seller to the trade that occurs such that i the trade is in the buyer seller core and ii some people are induced to enter the buyer seller meeting with money

transportation fuels policy since the opec embargo paved with good intentions a long line of research investigates whether the retail prices of electricity and natural gas send proper signals about scarcity in order to induce efficient consumption historically regulated utilities have not designed tariffs that set marginal prices equal to marginal costs currently some jurisdictions are opening the retail sectors to competition via retail choice these new regimes replace imperfect regulation with imperfect competition as the process by which retail tariffs are formed we discuss the challenges in evaluating the efficiency of tariffs and present evidence of how pricing has changed in markets with retail choice

the welfare cost of capital income taxation in a growing economy the welfare cost of capital income taxation is analyzed in a general equilibrium framework where the private sector is represented by a competitive household endowed with perfect foresight and an infinite life the value of the welfare cost depends essentially on the elasticity of substitution between capital and labor in the production function numerical estimates are presented for different values of the parameters of the model the welfare gain obtained by the abolition of the capital income tax is smaller when the private sector is not endowed with perfect foresight it is reduced by about 40 percent when expectations are myopic the allocation efficiency cost of the corporate tax dwarfs the intertemporal welfare cost

optimality of the friedman rule in economies with distorting taxes abstract we find conditions for the friedman rule to be optimal in three standard monetary models our main contribution is to shed light on two issues in the literature first the conventional view maintains that when money is a final good its services should be taxed moreover if money demand is interest inelastic its services should be taxed heavily we show that this view is incorrect second there is an ongoing controversy about whether the optimality of the friedman rule is connected to the intermediate goods result from public finance we resolve this controversy by showing a deep connection between these results

the liquidity trap the real balance effect and the friedman rule this paper studies the behavior of the economy and the efficacy of monetary policy under zero nominal interest rates using a model with population growth that nests as a special case a more conventional specification in which there is a single infinitely lived representative agent the paper shows that with a growing population monetary policy has distributional effects that give rise to a real balance effect thereby eliminating the liquidity trap these same distributional effects however can also work to make many agents much worse off under zero nominal interest rates than they are when the nominal interest rate is positive

the welfare cost of factor taxation in a perfect foresight model this paper examines the marginal efficiency cost of various factor taxes in a dynamic general equilibrium model the au thor solves for the excess burden of anticipated and unanticipated t emporary and permanent tax policies using a range of estimates for taste and technology parameters he finds excess burdens larger than those indicated by previous studies that use static models these exc ess burdens are sensitive to parameter values and timing however th e rankings of alternative tax policies turn out to be insensitive to structural parameter values copyright 1987 by university of chicago press

gresham s law in a lemons market for assets the authors describe a simple environment in which assets of varying qualities may be used for transactions and consumption the quality of an asset is known to the seller but not to the buyer this feature generates a negative relationship between the transactions velocities of assets and their rates of return they also discuss several versions of gresham s law that hold in this environment

inequality and social discounting we explore steady state inequality in an intergenerational model with altruistically linked individuals who experience privately observed taste shocks when the welfare function depends only on the initial generation efficiency requires immiseration inequality grows without bound and everyone s consumption converges to zero we study other efficient allocations in which the welfare function values future generations directly placing a positive but vanishing weight on their welfare the social discount factor is then higher than the private one and for any such difference we find that consumption exhibits mean reversion and that a steady state cross sectional distribution for consumption and welfare exists with no one trapped at misery

sub optimality of the friedman rule in townsend s turnpike and stochastic relocation models of money do finite lives and initial dates matter abstract the friedman rule a widely studied prescription for monetary policy is optimal in townsend s turnpike model of money it is not so in the overlapping generations version of his stochastic relocation model of money we investigate these monetary models in the light of this disparity to this end we create a modified version of the turnpike model that generates the same stationary monetary equilibria as does the two period overlapping generations model with random relocation we exploit this equivalence to explain the aforementioned disparity we also discuss the importance of whether or not the economy has an initial date

lump sum taxation and the superneutrality and optimum quantity of money in life cycle growth models abstract the question of superneutrality and the optimum quantity of money is addressed in a model where money services enter the utility function and where individuals have finite lives it is demonstrated that the existing result in the literature regarding a positive relationship between money creation and the steady state capital intensity and welfare is not due to monetary policy per se on the contrary this is shown to arise because of the intergenerational wealth effects embedded in the manner in which money is created assuming that preferences are separable between consumption goods and real balances and that the consumption goods are normal it is proved that i money is superneutral and ii any other money supply rule is pareto inferior to the chicago rule provided that the government also embarks on a policy of wealth redistribution across generations through the imposition of appropriate lump sum taxes and transfers

asset trading mechanisms and expansionary policy abstract previous authors have argued that the otimal monetary policy is contractionary if buyers value consumption substantially more than sellers there is some randomness and informational constraints make asset trading useful we show that there is an incentive compatible expansionary policy that dominates all incentive compatible contractionary policies
