habit formation and the persistence of monetary shocks this paper studies the persistent e ects of monetary shocks on output previous empirical literature documents this persistence but standard general equilibrium models with sticky prices fail to generate output responses beyond the duration of nominal contracts this paper constructs and estimates a general equilibrium model with price rigidities habit formation and costly capital adjustment the model is estimated via maximum likelihood using u s data on output real money balances and the nominal interest rate econometric results suggest that habit formation and adjustment costs to capital play an important role in explaining the output e ects of monetary policy in particular impulse response analysis shows that the model generates persistent hump shaped output responses to monetary shocks

inflation targeting under asymmetric preferences this paper develops and estimates a game theoretical model of inflation targeting where the central banker s preferences are asymmetric around the targeted rate specifically positive deviations from the target can be weighted more or less severely than negative ones in the central banker s loss function it is shown that some of the previous results derived under the assumption of symmetry are not robust to this generalization of preferences estimates of the central banker s preference parameters for canada sweden and the uk are statistically different from the one implied by the commonly used quadratic loss function

determinants of the current account balance in the united states this article studies the role of public and private imbalances in the behaviour of the current account balance in the united states in the context of an intertemporal model the estimation evaluates the effects of public and private imbalances on the dynamics of the current account correlation coefficients support the ricardian equivalence higher budget deficit correlates with a reduction in private consumption and an increase in private savings government saving does not vary significantly with macroeconomic variables in the short or in the long run in contrast fluctuations in government investment vary significantly with a number of economic variables in the long and in the short run accordingly fluctuations in the budget deficit are likely to be driven by fluctuations in public investment in contrast to government savings private savings vary significantly with macro variables in the long and in the short run fluctuations in private investment appear less evident compared to that in privat

habit formation in consumption and its implications for monetary policy models this paper explores a monetary policy model with habit formation for consumers in which consumers utility depends in part on current consumption relative to past consumption the empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with tremendous condence largely because the habit formation model captures the gradual hump shaped response of real spending to various shocks the paper then embeds the habit consumption specication in a monetary policy model and nds that the responses of both spending and inflation to monetary policy actions are signicantly improved by this modication jel d12 e52 e43

why does private consumption rise after a government spending shock recent empirical evidence suggests that private consumption is crowded in by government spending this outcome violates existing macroeconomic theory according to which the negative wealth effect brought about by a rise in public expenditure should decrease consumption

the macroeconomic effects of lockdown policies abstract a tractable incomplete market model with endogenous unemployment risk sticky prices real wage rigidity and a fiscal side is calibrated to euro area countries and used to analyze the macroeconomic effects of lockdown policies modeling them as a shock to the extensive margin of labor adjustment a rise in separations produces large and persistent negative effects on output unemployment and welfare raises precautionary savings and lowers inflation in line with early evidence about inflation dynamics modeling lockdowns as a shock to the intensive margin a fall in labor utilization produces small and short lived macroeconomic and welfare effects and implies a counterfactual rise in inflation conditional on a lockdown separation shock raising public spending or extending ui benefits by large amounts is much more effective in stimulating the economy than during normal times quantitatively however the ability of such policies to flatten the output and unemployment curves remains limited even though these policies can alleviate a reasonable share of the aggregate welfare losses from the lockdown

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

dynamic effects of financial intermediation over the business cycle ping wang this paper provides a empirical evidence that the financial intermediation disturbances can generate business cycles we examine three countries whose financial sectors are fully developed but quite distinct in their institutional and regulatory circumstances thus we can infer whether financial intermediation disturbances differ across dissimilar financial environments we find that the dynamic responses of output to financial intermediation shocks exhibit similar patterns in all cases studied however the various institutional and regulatory circumstances have generated different propagation mechanisms transmitting the financial disturbance to output in ways that lead the magnitudes of the responses to deviate across economies jel e32 e44 i introduction does the financial sector veil the real economy although some economists such as lucas 1988 argue that financial factors are over stressed there is a growing literature that theoretically cultivates the channels through which financial intermediation can influence economic fluctuations and long run growth rather than focus on the traditional monetary transmission mechanism this literature plants itself in the microfoundations of asymmetric information and contract theory the new financial intermediation literature stems from seminal works by diamond 1984 townsend 1983a 1983b and boyd and prescott 1986 that demonstrate that in the presence of private information and costly state verification it is optimal for borrowing and lending to be conducted under financial intermediary arrangements these ideas were then extended by williamson 1987 to show how disturbances in the financial intermediation sector can generate business cycle fluctuations essentially when investment projects become more risky or difficult to evaluate loan supply falls and business cycle movements emerge 1 moreover other financial intermediation impulses are likely to be important as well these include changes to the institutional framework or the regulatory environment and any other event that enhances or hinders the intermediaries capacity to allocate capital efficiently among competing alternative uses e g financial innovation yet despite the theoretical rhetoric on the importance of financial intermediation to output fluctuations the empirical relevance of financial intermediation remains an unsettled question this paper brings us one step closer to the solution by econometrically identifying structural financial intermediation disturbances and estimating their effect on output movements in three major industrialized countries germany the united kingdom and the united states we choose these three advanced economies not only because their financial sectors are fully developed but also because their distinct banking structures and regulatory environments are capable of generating and transmitting financial intermediation disturbances in different ways that is the depth of financial intermediation is relatively similar across countries therefore the cross country analysis allows us to focus on the ability of financial intermediation to generate short run cycles and to draw some suggestive insights regarding the role of regulatory and institutional factors across countries the existing empirical evidence linking financial factors to real economic activity has involved noticing statistical correlations between some financial variables and some real variables goldsmith 1969 using data from 1860 to 1963 showed that there is a positive relationship between economic development and the size of the financial sector kuznets 1971 in a cross section study of 57 developed and developing economies found that the share of banking insurance and real estate in gross domestic product rises as income increases mckinnon 1973 showed that the ratios of private credit to national income and a broad monetary aggregate to national income are positively related to per capita income

measuring the effects of fiscal policy measuring the effects of discretionary fiscal policy is both difficult and controversial as some explicit or implicit identifying assumptions need to be made to isolate exogenous and unanticipated changes in taxes and government spending studies based on structural vector autoregressions typically achieve identification by restricting the contemporaneous interaction of fiscal and non fiscal variables in a rather arbitrary way in this paper we relax those restrictions and identify fiscal policy shocks by exploiting the conditional heteroscedasticity of the structural disturbances we use this methodology to evaluate the macroeconomic effects of fiscal policy shocks in the u s before and after 1979 our results show substantive differences in the economy s response to government spending and tax shocks across the two periods importantly we find that increases in public spending are in general more effective than tax cuts in stimulating economic activity a key contribution of this study is to provide a formal test of the identifying restrictions commonly used in the literature

the macroeconomic effects of distortionary taxation abstract prescott 1986 estimates that technology shocks account for 75 of the fluctuations in the postwar u s economy this paper reestimates the contribution of technological change for a standard business cycle model that includes a public sector and fiscal disturbances i find that a significant fraction of the variance of aggregate consumption investment output capital stock and hours of work can be explained by disturbances in labor and capital tax rates and government consumption i also use the model to quantify the welfare costs of capital and labor taxation for both the time series and welfare calculations maximum likelihood estimates of taste technology and policy parameters are used

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

the role of dispute settlement procedures in international trade agreements although disputes are typically treated as synonymous with concerns about enforcement in economic models of trade agreements in reality most wto disputes seem to concern the interpretation of vague provisions or instances where the agreement is silent and some have suggested that the wto s dispute settlement body dsb could usefully grant exceptions to rigid contractual obligations these activist dsb roles could help complete an incomplete contract but how activist should the dsb be should dsb rulings set precedent we address these questions by characterizing the optimal choice of contract form and dsb mandate under various contracting conditions jel codes d02 d78 d86 f13 k12 k33

infrastructure provision and macroeconomic performance this paper studies the differences between private and government provision of infrastructure capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for fiscal policy a subsidy to private providers of infrastructure is preferable to direct government provision irrespective of how the subsidy or expenditure is financed the case for private provision is much stronger in economies characterized by high levels of congestion the choice between private and government provision also has a crucial effect on the design of optimal fiscal policy 2011 elsevier b v all rights reserved

when does government debt crowd out investment summary we examine when government debt crowds out investment for the us economy using an estimated new keynesian model with detailed fiscal specifications and accounting for monetary and fiscal policy interactions whether investment is crowded in or out in the short term depends on policy shocks triggering debt expansions higher debt can crowd in investment for cutting capital tax rates or increasing government investment contrary to the conventional view no systematic relationships between real interest rates and investment exist explaining why reduced form regressions are inconclusive about crowding out at longer horizons distortionary financing is important for the negative investment response to debt copyright 2013 john wiley sons ltd

excludable and non excludable public inputs consequences for economic growth non excludable and excludable public inputs are introduced into an endogenous growth model we derive the equilibrium growth rate and design the optimal tax and user cost structure emphasizing the role of congestion and its consequences for the government s budget the latter comprises fee and tax revenues that are used to finance the public inputs although they may generate insufficient revenue to do so entirely we extend the model to allow for monopoly pricing of the user fee by the government most of the analysis is conducted for general production functions consistent with endogenous growth but the ces technology is also considered a vast literature has evolved emphasizing the role of public investment as a determinant of economic growth among the earliest contributions arrow and kurz 1970 is particularly significant while the seminal work of barro 1990 has been especially influential with respect to the contemporary endogenous growth literature stimulated by aschauer s 1989 findings pertaining to the high rate of return on public capital several authors have explored various aspects of the role of public capital in stimulating economic growth for example baxter and king 1993 and fisher and turnovsky 1998 examine the interaction between public and private capital in a ramsey type growth model while futagami et al 1993 perform a similar type of analysis in an endogenous growth context glomm and ravikumar 1997 analyse the growth effects of productive public spending in an overlapping generations setup extending the framework to include majority voting and alternative compositions of publicly provided goods and services they also indicate private alternatives to public provision but do not pursue this in detail cassou and lansing 1998 focus on the relationship between private and public capital showing how the evolution of the ratio between the two in the us economy since 1925 is broadly consistent with the predictions of a simple ramsey growth model they also show how the productivity slowdown in the us economy since the 1970s is more likely due to increasing tax rates than to non optimal public investment policy much of the literature including barro treats the public input as a pure public good freely available without restrictions or impediments to all agents in the economy but the public goods literature identifies many different characteristics that most public goods in fact exhibit notably the presence of rivalry and or excludability see e g cornes and sandler 1996 thus the treatment of a public

estimation and control of an optimization based model with sticky prices and wages abstract this paper provides estimates of an optimization based equilibrium model with sticky prices and wages the estimated model is used to analyse the welfare properties of various interest rate rules for conducting monetary policy an important feature of this model is that it involves a tradeoff between the variances of price and wage inflation and the output gap this tradeoff implies that it is desirable for the monetary authority to respond to wage inflation in addition to price inflation output and past interest rates when setting the current interest rate the issue whether wages and prices can be indexed to steady state inflation has important implications both for the characterization of optimal interest rate rules and interest rate volatility in particular optimal policy in the presence of indexation induces implausibly high steady state inflation

propagation mechanisms for government spending shocks a bayesian comparison the inability of a simple real business cycle model to predict a rise in consumption in response to increased government expenditures observed in many empirical studies has stimulated the development of alternative theories of government spending shocks using the bayesian approach we evaluate the quantitative performance of five extant models and find that neither of the considered transmission mechanisms for government spending helps improve the fit of the baseline model moreover we find that consumption decreases in all estimated models in response to a rise in government spending

endogenous cases and the evolution of the common law i develop a dynamic model of judge made law in which the ideal legal rule is unknown but can be learned in contrast to existing articles the flow of cases heard by the court is affected by the court s prior decisions the model highlights the significance of this feedback in explaining when and why the court will write broader or narrower opinions and the long run properties of common law in equilibrium the law settles endogenously because the incentives to make legally controversial choices disappear as the law evolves settled law exhibits residual uncertainty and ambiguity and potentially implements inefficient outcomes

fiscal shocks and their consequences this paper investigates the response of hours worked and real wages to fiscal policy shocks in the post world war ii us we identify these shocks with exogenous changes in military purchases and argue that they lead to a persistent increase in government purchases and tax rates on capital and labor income and a persistent rise in aggregate hours worked as well as declines in real wages the shocks are also associated with short lived rises in aggregate investment and small movements in private consumption we describe and implement a methodology for assessing whether standard neoclassical models can account for the consequences of a fiscal policy shock simple versions of the neoclassical model can account for the qualitative effects of a fiscal shock once we allow for habit formation and investment adjustment costs the model can also account reasonably well for the quantitative effects of a fiscal shock

intratemporal substitution between private and government consumption the case of japan abstract in this paper we use japanese quarterly data to examine the relationship between private and government consumption we apply a two step estimation procedure and find additional evidence that the two types of consumption may be complements or unrelated

government spending entry and the consumption crowding in puzzle this article documents empirically that net firm entry robustly rises after a u s government spending expansion we use this new finding to test the empirical validity of various model features that have been proposed to generate consumption crowding in after positive expenditure shocks endogenous entry models typically fail to generate the observed joint increase in consumption and entry model features that dampen the wealth effect such as rule of thumb households or complementarity between labor and consumption in preferences tend to reduce entry we show that utility or productivity enhancing public spending can reconcile the model with our documented fact and performs well empirically

fiscal policy pricing frictions and monetary accommodation this paper empirically investigates whether the theoretical conditions for government expenditure expansions to be effective hold for the data we ask whether the necessary conditions for fiscal effectiveness are relevant on average and in special circumstances that capture features of the recent crisis fiscal policy can be an effective countercyclical tool if monetary policy accommodates the fiscal expansion if expectations about future output growth and inflation are constant and if structural relationships are invariant to the policy change recent expansions are unlikely to produce large output multipliers or have important debt or inflation effects credible deficit and debt reduction schemes can produce sizeable output multipliers fabio canova and evi pappa

the international ramifications of tax reforms supply side economics in a global economy this paper studies tax reforms in a dynamic model of a global economy calibrated to current u s and european tax policies world capital markets add consumption smoothing and income redistribution effects that alter closed economy predictions in the absence of taxes on foreign interest welfare gains of eliminating u s income taxes are enlarged by up to 34 percent at the expense of european losses caused by transitional declines in consumption and leisure and a permanent capital outflow in contrast if foreign interest is taxed the same tax reform reduces u s welfare 0 7 percent and increases european welfare 1 8 percent copyright 1998 by american economic association

what accounts for the changes in u s fiscal policy transmission using vector autoregressions on u s time series for 1957 79 and 1983 2004 we find government spending shocks to have stronger effects on output consumption and wages in the earlier period we try to account for this observation within a dsge model featuring price rigidities and limited asset market participation specifically we estimate the structural parameters of the model for both periods by matching impulse responses model based counterfactual experiments suggest that most of the changes in fiscal policy transmission are accounted for by increased asset market participation and the more active monetary policy of the volcker greenspan period

intrinsic motivation in public service theory and evidence from state supreme courts abstractthis paper provides a theoretical and empirical analysis of the intrinsic preferences of state appellate court judges we construct a panel data set using published decisions from all state supreme courts from 1947 to 1994 we estimate the effects of changes in judges employment conditions on a number of measures of judicial performance the results are consistent with the hypothesis that judges are intrinsically motivated to provide high quality decisions and that at the margin they prefer quality over quantity when judges face less time pressure whether from the introduction of an intermediate appellate court the weakening of electoral demands or an increased salary they write more well researched opinions that are cited more often by other judges these effects are strongest when judges have more discretion to select their portfolios of cases

can fiscal spending stimulate private consumption abstract empirically government expenditure shocks seem to crowd in private consumption while neoclassical and new keynesian models predict crowding out we derive conditions under which a government in utility specification in a sticky price model helps to reconcile theory and evidence

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

episodes of war and peace in an estimated open economy model we analyze the effects of world wars on the macroeconomic dynamics of the u s france germany and the uk by means of an estimated open economy model the model allows wars to affect the economy through capital depreciation sovereign default a military draft household preferences and spillovers on other exogenous processes productivity investment trade policy variables if the bulk of fluctuations during war episodes can be explained by the rise in government spending in the u s other factors are crucial in other countries we also discuss the size and state dependence of public spending multipliers and a counterfactual welfare exercise

monetary fiscal policy interactions and fiscal stimulus abstract increases in government spending trigger substitution effects both inter and intra temporal and a wealth effect the ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption higher future taxes create a strong negative wealth effect while the active monetary response increases the real interest rate this paper estimates markov switching policy rules for the united states and finds that monetary and fiscal policies fluctuate between active and passive behavior when the estimated joint policy process is imposed on a conventional new keynesian model government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized the paper reports the model s predictions of the macroeconomic impacts of the american recovery and reinvestment act s implied path for government spending under alternative monetary fiscal policy combinations

learning while setting precedents a decision maker dm must address a series of problems over time each period a random case arises and the dm must make a yes or no decision which we call a ruling she is uncertain about the correct ruling until she conducts a costly investigation a ruling establishes a precedent which may be costly to violate in the future we compare the dm s incentive to acquire information the evolution of standards and the social welfare under two institutions nonbinding precedent and binding precedent under nonbinding precedent the dm is not required to follow previous rulings but under binding precedent she must follow previous rulings where applicable we find that compared to nonbinding precedent the incentive for information acquisition is stronger under binding precedent in earlier periods when few precedents exist but as more precedents are established over time the incentive for information acquisition becomes weaker under binding precedent even though erroneous rulings may be perpetuated under binding precedent social welfare can be higher because of the more intensive investigation conducted early on

distortionary taxation and labor supply this paper examines empirically the effects of distortionary taxation on labor supply using a general equilibrium framework the long term relations predicted by the model are derived and tested using data from canada united states germany and japan in all these countries labor tax changes are found to be persistent and to have played an important role in the observed downward trend in hours worked

why has regional income convergence in the u s declined the past thirty years have seen a dramatic decrease in the rate of income convergence across states and in population flows to wealthy places these changes coincide with 1 an increase in housing prices in productive areas 2 a divergence in the skill specific real returns to living in productive places 3 a redirection of low skilled migration and 4 diminished human capital convergence due to migration we develop a model where falling housing supply elasticity and endogenous labor mobility generates these patterns using a new panel measure of housing supply regulations we demonstrate the importance of this channel income convergence continues in less regulated places while it has stopped in more regulated places

anticipated fiscal policy and adaptive learning abstract the impact of anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations is considered agents are assumed to combine limited structural knowledge with a standard adaptive learning rule these issues are analyzed using two well known set ups an endowment economy and the ramsey model in our scenario there are important deviations from both rational expectations and purely adaptive learning the approach could be applied to other frameworks

an empirical analysis on the substitutability between private consumption and government purchases abstract this paper estimates substitutability of government purchases for private consumption using an optimal consumption model the utility function features several types of nonseparabilities the paper finds that gmm estimates are affected by the specification of nonseparability between private consumption and government purchases by the restriction of time separability and by the measurement of real interest rates

the effects of discretionary fiscal policy on macroeconomic aggregates a reappraisal fiscal stimuli to recover a cascade of academic and layman articles debate the effectiveness of fiscal policy in stimulating the economy backed up by different economic models and empirical support this essay surveys the theoretical predictions and recent empirical vector autoregression var evidence on the short run effects of discretionary fiscal policy on macroeconomic aggregates

an equilibrium model of the business cycle with household production and fiscal policy the authors estimate a dynamic general equilibrium model of the u s economy that includes an explicit household production sector and stochastic fiscal variables they use their estimates to investigate two issues first the authors analyze how well the model accounts for aggregate fluctuations they find that household production has a significant impact and reject a nested specification in which changes in the home production technology do not matter for market variables second the authors study the effects of some simple fiscal policy experiments and show that the model generates different predictions for the effects of tax changes than similar models without home production copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

types and patterns an experimental east west german comparison of cooperation and solidarity abstract in a study of public good and solidarity experiments conducted in eastern and western germany we found in both games that eastern subjects behave in a significantly more selfish manner than do western subjects besides that we found that many qualitative results of both data sets are similar since our experiments were conducted in two parts of one nation we present an unusually well controlled cross cultural study by avoiding difficulties that usually arise in multinational settings we conclude that cooperation and solidarity behavior seem to depend strongly on different culture specific norms resulting from opposing economic and social histories in the two parts of germany

real government size automatic feedback rules and the measured effectiveness of fiscal policy this paper argues that as intervention fiscal policy means more than simply any change in government spending and this requires of fiscal analysis a measure that separates the allocative from the counter cyclical activities of government defining intervention as an optimal policy rule that responds automatically to privately unanticipated variations in output a general equilibrium model is built to separate the supply side effects of desired changes in the size of government from demand side interventions designed to stimulate aggregate demand the model is tested using the results of a public choice investigation of the real size of government ferris and west 1996 that exercise produces a measure of desired size and through its residual an implicit measure of intervention the paper tests the prediction that increases in desired size increase aggregate supply and that ex post measures of fiscal intervention can be recovered and tested for their effect on aggregate output the test uses citibase

a method for taking models to the data abstract this paper develops a method for combining the power of a dynamic stochastic general equilibrium model with the flexibility of a vector autoregressive time series model to obtain a hybrid that can be taken directly to the data it estimates this hybrid model via maximum likelihood and uses the results to address a number of issues concerning the ability of a prototypical real business cycle model to explain movements in aggregate output and employment in the postwar us economy the stability of the real business cycle model s structural parameters and the performance of the hybrid model s out of sample forecasts

the dominant borrower syndrome abstractthe financing channel of a fiscal stimulus matters for the size and the sign of the fiscal multiplier we develop a general equilibrium model where a fiscal stimulus is partially bank funded and the government becomes the dominant borrower from banks relative to entrepreneurs this leads to a negative impact on credit spreads investment and a contraction in output we support our story with a structural vector autoregression for a sample of developing countries featuring the dominant borrower syndrome

fiscal trends in real economic aggregates using cointegration analysis the authors examine long term interactions between fiscal variables and the consumption output and leisure labor ratios the motivation is to test if fiscal trends are an independent source of stochastic trends underlying the long run behavior of real economic aggregates the authors results support the presence of fiscal trends and can be interpreted quite well in terms of the equilibrium approach to fiscal policy they suggest that neoclassical growth models that embed fiscal trends and distinguish between components of government purchases are more consistent with the data than simple real business cycle models copyright 1995 by ohio state university press

fiscal stimulus and the role of wage rigidity abstract in this paper we study the impact of an expansion in public spending in an economy characterized by limited asset market participation and sticky wages the flexible wage version of the model implies strong expansionary effects on output and consumption but also a counterfactual increase in real wages the introduction of sticky wages besides being a realistic addition solves this problem and preserves the expansionary effects on output and consumption moreover once we introduce segmentation in the labor market sticky wages are even essential to obtain expansionary effects

time to build consumption complementarity and fiscal stimulus abstract we show that time to build which creates a time gap between government spending and the accumulation of public goods is an important element that weakens the effectiveness of fiscal stimulus in the environment where private consumption and public goods are edgeworth complements adding time to build to the model delays the timing of utility enhancing effects of an increase in government expenditure leading households to shift consumption from today to the future the expansionary effect of government spending is hence dampened which contrasts existing studies with edgeworth complementarity between private and public consumption

the evolution of common law we present a model of lawmaking by appellate courts in which judges influenced by policy preferences can distinguish precedents at some cost we find a cost and a benefit of diversity of judicial views policy motivated judges distort the law away from efficiency but diversity of judicial views also fosters legal evolution and increases the law s precision we call our central finding the cardozo theorem even when judges are motivated by personal agendas legal evolution is on average beneficial because it washes out judicial biases and renders the law more precise our paper provides a theoretical foundation for the evolutionary adaptability of common law

liquidity constraints and the substitutability between private and government consumption the role of military and non military spending i introduction using data for a number of economies we investigate i the relationship between private consumption and two types of government spending military and non military and ii the severity of liquidity constraints because of their importance for macroeconomic modeling in theory and practice 1 both issues have been the subjects of considerable theoretical and empirical investigation on the issue of liquidity constraints the most influential research has relied on hall s 1978 euler equation approach to the permanent income hypothesis in an attempt to reconcile hall s and flavin s 1981 methodologies hayashi 1982 modified hall s martingale result to allow for the possibility that a subset of consumers are liquidity constrained and showed that liquidity constraints can result in consumption s excess sensitivity to current income campbell and mankiw 1989 1990 1991 and jappelli and pagano 1989 have applied hayashi s methodology using data from the u s and several other oecd countries on the substitutability issue aschauer 1985 has modified hall s euler equation to allow for substitutability between government spending and private consumption and found that the two are substitutes for the u s karras 1994 however using a similar approach and data for 30 countries concludes that private and government consumption are better described as complementary or unrelated liquidity constraints and substitutability have been combined in studies by graham and himarios 1991 cushing 1992 and graham 1993 using u s data and by evans and karras 1996 for a number of countries a crucial limitation of most of these studies is the use of aggregate government consumption data which counterintuitively imposes a common substitutability parameter on all components of government spending 2 using recently available time series data for a large number of countries the present paper relaxes this restriction by decomposing government consumption into military and non military components enabling us to separately identify their relationship to private consumption the allocation of government consumption between military and non military functions has varied greatly across countries the appendix reports the average size of military and non military government shares in gdp as well as the military non military ratio by country over the 1970 1989 period average military expenditure as a fraction of gdp for example has ranged in our sample from 0 11 in mexico to 12 30 in jordan similarly the fraction of government consumption absorbed by military expenditure has ranged from 1 09 in mauritius to 66 82 in poland this sizable variability is promising in terms of cross sectional identification power but it also suggests that the estimated parameters must not be assumed to be common across countries the estimated model is derived in section ii which combines liquidity constraints and substitutability by nesting the approaches of hayashi 1982 and aschauer 1985 in the same section we discuss data sources and the estimation strategy which permits the estimated parameters to vary by country in a way that helps determine how they are influenced by country specific factors section iii estimates the model for a panel of the 66 countries for which annual data on all series are available for the 1970 1989 period the paper s main conclusions are given in section iv ii methodology and data we assume that consumers in economy i at time t derive utility from effective consumption c sup which we define as 1 mathematical expression omitted where c is private consumption g sup m and g sup nm are the military and non military components of government consumption the parameters theta sup m and theta sup nm measure the degree of substitutability between c and g sup m and c and g sup nm respectively

legal realism for economists abstract economists have made great progress in understanding the incentives and behavior of actors who operate outside of traditional economic markets including voters legislators and bureaucrats the incentives and behavior of judges however remain largely opaque do judges act as neutral third party enforcers of substantive decisions made by others are judges ordinary policymakers who advance whatever outcomes they favor without any special consideration for law as such emerging recent scholarship has started to explore more nuanced conceptions of how law facts and judicial preferences may interact to influence judicial decisions this work develops a perspective on judging that can usefully be understood as the modern manifestation of american legal realism a jurisprudential movement of lawyers judges and law professors that flourished in the early twentieth century the purpose of this essay is to introduce in simplified form the realist account of judicial decision making to contras

debt dependent effects of fiscal expansions abstract economists often postulate that fiscal expansions are less stimulative when government debt is high than when it is low empirical evidence however is ambiguous using a nonlinear neoclassical growth model we show that the difference in government spending effects between high and low debt environments depends on the wealth effect on labor supply and on whether the government uses taxes or spending to retire debt because of interrelated state variables structural var estimations conditioning on debt alone can fail to isolate debt dependent effects also uncertainty on when the government will conduct fiscal consolidations generates wide confidence bands for spending multipliers further complicating efforts to estimate debt dependent government spending effects

using the law to change the custom the custom often acts as a powerful hindrance to equity increasing changes in this paper we present a simple model of legal dualism in which a progressive legal reform can under certain conditions shift the conflicting custom in the direction intended by the legislator formal law then acts as an outside anchor that exerts a magnet effect on the custom we also characterize the conditions under which a moderate reform performs better than a radical one in improving the welfare of the disadvantaged sections of the population we illustrate our insights using examples on inheritance marriage and divorce in sub saharan africa and india

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

self centered and other regarding behavior in the solidarity game this paper revisits the experiment on the solidarity game by selten and ockenfels selten r ockenfels a 1998 an experimental solidarity game journal of economic behavior and organization 34 517 539 we replicate the basic design and extend it to test the robustness of the fixed total sacrifice effect and the applied strategy method our results only partially confirm the validity of the fixed total sacrifice effect in a treatment with constant group endowment rather than constant winner endowment the predominance of fixed total sacrifice behavior is replaced by fixed relative gift behavior we do not find correlations between actual gift behavior and measures of empathy driven pro social behavior used in social science

habit formation and fiscal transmission in open economies in this paper we analyze the ability of an open economy version of the neoclassical model to account for the time series evidence on fiscal policy transmission revisiting the evidence we find that i government spending raises output while inducing a simultaneous decline of investment and the current account and ii the responses of output and investment are more muted in more open economies while current account deficits tend to be larger turning to the model we explore the role of habit formation for fiscal policy transmission specifically we show that the model can account for the evidence if consumption behavior is characterized by habit formation and the terms of trade adjust endogenously

fiscal policy and occupational employment dynamics we document substantial heterogeneity in occupational employment dynamics in response to government spending shocks in the united states employment rises most strongly in service sales and office pink collar occupations by contrast employment in blue collar occupations is hardly affected by fiscal policy we provide evidence that occupation specific changes in labor demand are key for understanding these findings we develop a business cycle model that explains the heterogeneous occupational employment dynamics as a consequence of composition effects due to heterogeneous employment changes across industries and occupation specific within industry employment shifts due to differences in the short run substitutability between labor and capital services across occupations

the role of capital and labour in shaping the environmental effects of fiscal stimulus abstract although the macroeconomic consequences of short term fiscal stimulation packages have been thoroughly analysed in the literature still relatively little is known about their environmental effects we discuss an important channel through which short run expansionary fiscal policy influences greenhouse gas emissions we show that fiscal policy exerts its impact not only by increasing general level of economic activity but also by changing the composition of factors of production capital and labour using the dynamic stochastic general equilibrium model of economy we demonstrate that fiscal expansion results in a shift from capital intensive to more labour intensive technologies our panel study proves that the latter tends to be associated with lower emissions of greenhouse gases per unit of production hence our analysis demonstrates that an extensive use of fiscal stimulus during recessions can significantly reduce the environmental burden of the additional units of gdp

contracting in the shadow of the law economic models of contract typically assume that courts enforce obligations based on verifiable events corresponding to the legal rule of specific performance as a matter of law this is not the case this leaves open the question of optimal contract design given the available remedies used by the courts this article shows that american standard form construction contracts can be viewed as an efficient mechanism for implementing building projects given existing legal rules it is shown that a central feature of these contracts is the inclusion of governance covenants that shape the scope of authority and regulate the ex post bargaining power of parties our model also implies that the legal remedies of mistake impossibility and the doctrine limiting damages for unforeseen events developed in the case of hadley v baxendale are efficient solutions to the problem of implementing complex exchange

cyclical effects of government s employment and goods purchases distinguishing between the goods purchase and employee compensation components of government spending is important shocks to government goods purchases and shocks to government employment have the opposite effects on private output private employment and private investment moreover with this distinction in place quantitative analysis reveals that government spending is no longer a significant driving source of the u s business cycle on the contrary the components of government spending are procyclical in the u s data primarily because of their positive responses to the output fluctuations generated by technology shocks copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

downward nominal wage rigidity and state dependent government spending multipliers abstract despite much empirical evidence on business cycle dependent government spending multipliers the theoretical channels underlying such results are uncertain in an environment with involuntary unemployment this paper shows that downward nominal wage rigidity which arises only in recessions can generate business cycle dependent government spending multipliers in line with keynesian views a demand stimulus reduces unemployment in recessions and may not drive up inflation and wages as in expansions thus the positive income effects from reduced unemployment and weaker crowding out effects from a smaller increase in the real interest rate enhance the expansionary spending effects in recessions the theoretical implications are largely consistent with existing empirical evidence on business cycle dependent government spending effects on key macroeconomic variables

factor income taxation in a horizontal innovation model we consider the optimal factor income taxation in a standard r d model with technical change represented by an increase in the variety of intermediate goods in the model there are externalities both to working and to saving due to market power by firms incomplete appropriability of the benefits of inventions and the cost of economic activity in terms of public expenditures redistributing the tax burden from labor to capital will increase employment but in most cases reduce the rate of growth with conflicting effects on the deadweight loss from the externalities under plausible calibrations of the model the optimal tax rate on capital will be sizable

tales of fiscal adjustment fiscal adjustments why they can be expansionary this paper examines the evidence on fiscal adjustments in oecd countries from the early 1960s to today the results shed light on the recently observed phenomenon of fiscal tightening that produces non keynesian expansionary effects one interpretation is that a serious fiscal tightening increases demand wealth rises when future tax burdens decline and when interest rates decline credibility is restored and inflation or default risks abate both consumption and investment rise for this effect to produce an expansion the tightening must be sizeable and occur after a period of stress when the budget is quickly deteriorating and public debt is building up another interpretation emphasizes the supply side typically a fiscal consolidation based on tax increases is short lived to be long lasting it must include cuts in public employment transfers and government wages to be politically possible such a policy must be supported by trade unions these measures result in more efficient labour markets and boost the supply side based both on statistical evidence and on a detailed analysis of ten cases of major fiscal adjustment this article provides cautious support to the supply side view without denying a more limited role for the demand side channel alberto alesina and silvia ardagna

great expectations and the end of the depression what ended the great depression in the united states this paper suggests that the recovery was driven by a shift in expectations this shift was triggered by president franklin delano roosevelt s fdr policy actions on the monetary policy side roosevelt abolished the gold standard and announced an explicit policy objective of inflating the price level to pre depression levels on the fiscal policy side roosevelt expanded real and deficit spending which helped make his policy objective credible the key to the recovery was the successful management of expecta tions about future policy roosevelt s rise to power is modeled as a policy regime change as in thomas sargent 1983 and peter temin and barry wigmore 1990 this paper formalizes temin and wigmore s argu ment in a repeated game setting using a dynamic stochastic general equilibrium dsge model and argues that the regime change can account for the recovery in the model a regime change means the elimination of certain policy dogmas that constrain the actions of the government the regime change generates an endogenous shift in expectations due to a coordination of mon etary and fiscal policy this coordination ended the great depression by engineering a shift in expectations from contractionary i e the private sector expected future economic contrac tion and deflation to expansionary i e the public expected future economic expansion and inflation the expectation of higher future inflation lowered real interest rates thus stimulating demand while the expectation of higher future income stimulated demand by raising permanent income

the case for nil votes voter behavior under asymmetric information in compulsory and voluntary voting systems in an informational voting environment we study the impact of an explicit nil vote option on the ballot when some voters are uninformed and face the swing voters curse we postulate a simple model of strategic voting in which voters entertain heterogeneous thresholds on legitimacy of different voting actions we predict that introducing a nil vote option reduces the number of uninformed and invalid votes increasing expected welfare in both voluntary and compulsory voting we test our model in a pen and paper laboratory experiment and find that the predictions of the model hold in the data for both voting systems

clearing up the fiscal multiplier morass bayesian prior predictive analysis of five nested dsge models suggests that model specifications and prior distributions tightly circumscribe the range of possible government spending multipliers multipliers are decomposed into wealth and substitution effects yielding uniform comparisons across models by constraining the multiplier to tight ranges model and prior selections bias results revealing less about fiscal effects in data than about the lenses through which researchers choose to interpret data when monetary policy actively targets inflation output multipliers can exceed one but investment multipliers are likely to be negative passive monetary policy produces consistently strong multipliers for output consumption and investment

constructing and estimating a realistic optimizing model of monetary policy abstract a dynamic stochastic general equilibrium dsge model with real and nominal both price and wage rigidities succeeds in capturing some key nominal features of u s business cycles additive technology shocks as well as multiplicative shocks are introduced and shown to be crucial monetary policy is specified as an interest rate targeting rule following developments in the structural vector autoregression var literature the interaction between real and nominal rigidities is essential to reproduce the liquidity effect of monetary policy the model is estimated by maximum likelihood on u s data and its fit is comparable to that of an unrestricted first order var besides producing reasonable impulse responses and second moments this model replicates a feature of u s business cycles never captured by previous research with dsge models that an increase in interest rates predicts a decrease in output two to six quarters in the future

the effects of fiscal shocks on employment and the real wage we study the transmission of fiscal shocks in the labor market we employ a structural var and base identification on the restrictions that shocks to government consumption investment and employment must raise output and deficits these restrictions hold in both prototype real business cycle rbc and new keynesian models shocks to government consumption and investment increase real wages and employment contemporaneously both at state level and in the aggregate the dynamics in response to employment shocks are mixed increases in government employment raise the real wage and total employment in the aggregate however in one third of the states they reduce total employment

two fiscal policy puzzles revisited new evidence and an explanation abstract this paper examines two fiscal policy puzzles related to the effects of government spending shocks contrary to theoretical predictions recent empirical evidence suggests a crowding in of consumption and a depreciation of the real exchange rate after a government spending increase while several studies have been made to reconcile the conflicting results this paper provides new time series evidence and proposes an alternative explanation using the japanese data the empirical responses of consumption and the real exchange rate after government spending shocks are shown to be well replicated by an estimated medium scale open economy dynamic stochastic general equilibrium dsge model augmented with i edgeworth complementarity between private and government consumption and ii productive public capital furthermore sensitivity analysis suggests that the combination of edgeworth complementarity home bias and incomplete asset market allows the model to account for an immediate increase in consumption and for a hump shaped depreciation of the real exchange rate after a government consumption shock this result is potentially important in preventing the model from showing the consumption real exchange rate anomaly after the shock

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

on fiscal multipliers estimates from a medium scale dsge model this paper contributes to the debate on fiscal multipliers in the context of a structural model i estimate a micro founded dynamic stochastic general equilibrium model that features a rich fiscal policy block and a transmission mechanism for government spending shocks using bayesian techniques for us data

government spending and private consumption some international evidence this paper investigates the relationship between private consumption and publicly provided goods and services for a number of countries the empirical results show that in the aggregate private and government consumption are best described as complementary in the sense that an increase in one raises the marginal utility of the other the strength of this relationship is shown to be negatively affected by the government size these findings are robust across all specifications tried copyright 1994 by ohio state university press

an estimated canadian dsge model with nominal and real rigidities this paper develops a dynamic stochastic general equilibrium dgse model for the canadian economy and evaluates the real effects of monetary policy shocks to generate high and persistent real effects the model combines nominal frictions in the form of costly price adjustment with real rigidities modelled as convex costs of adjusting capital and employment

house prices and government spending shocks we show that dynamic stochastic general equilibrium dsge models with housing and collateralized borrowing predict a fall in house prices following positive government spending shocks by contrast we show that house prices in the united states rise persistently after identified positive government spending shocks we clarify that the incorrect house price response is due to a general property of dsge models approximately constant shadow value of housing and that modifying preferences and production structure cannot help in obtaining the correct house price response properly accounting for the empirical evidence on government spending shocks and house prices using a dsge model therefore remains a significant challenge

fiscal policy in the new neoclassical synthesis we analytically derive the cyclical effects of fiscal policy shocks in a new neoclassical synthesis model price stickiness has the consequence that a rise in government demand affects labor demand while at the same time the usual wealth effect boosts labor supply the strength of the demand effect depends on the response of the real interest rate governed by the monetary policy regime when the central bank controls money growth fiscal expansions are deflationary and might even be contractionary whereas output wages and inflation can increase when the rise in the real interest rate is dampened by an interest rate rule however price stickiness alone is not sufficient to explain a rise in consumption as predicted by keynesian theory

a test of racial bias in capital sentencing this paper proposes a test of racial bias in capital sentencing based upon patterns of judicial errors in lower courts we model the behavior of the trial court as minimizing a weighted sum of the probability of sentencing an innocent and that of letting a guilty defendant free we de ne racial bias as a situation where the relative weight on the two types of errors is a function of defendant and or victim race the key prediction of the model is that if the court is unbiased ex post the error rate should be independent of the combination of defendant and victim race we test this prediction using an original dataset that contains the the race of the defendant and of the victim s for all capital appeals that became nal between 1973 and 1995 we nd robust evidence of bias against minority defendants who killed white victims in direct appeal and habeas corpus the probability of error in these cases is 3 and 9 percentage points higher respectively than for minority defendants who killed minority victims

growth and public debt what are the relevant trade offs the interplay between growth and public debt is addressed considering a barro type 1 endogenous growth model where public spending is financed through taxes on income and public debt debt is assumed to be a fixed proportion of gdp which is used as a policy parameter by the government we first show that when debt is a large enough proportion of gdp two distinct bgps may co exist one being indeterminate therefore local and global indeterminacy may arise and self fulfilling expectations appear as a crucial ingredient to understand the impact of debt on growth and on macroeconomic fluctuations we then exhibit two types of important trade off associated with self fulfilling expectations first we show that the lowest bgp is always decreasing with respect to the ratio of debt gdp while the highest one is increasing as a result depending on the bgp selected by agents expectations the relationship between debt and growth is not always negative second we show that the highest bgp which provides the highest welfare is always locally indeterminate while the lowest is always locally determinate therefore depending on the expectations of agents when debt is increasing large fluctuations associated to self fulfilling believes may occur and be associated at the same time with welfare losses if there is a coordination on the low steady state finally a simple calibration exercise allows to provide an understanding of the recent experiences of many oecd countries

legal efficiency and consistency abstract we analyze the efficiency and consistency of court decisions under common and civil law as a leading example we study the enforcement of property rights judges are of two types some are conservative and follow the precedent or the statute while others maximize social welfare when courts intervene ex post after the relevant economic choices have been made welfare maximizing courts face a commitment problem such an ex post bias has implications on the relative consistency and efficiency of each legal system surprisingly we find that court decisions are more consistent under common law than under civil law the welfare comparison between the two systems is instead ambiguous however in changing economic environments common law is more likely to dominate civil law because of its greater adaptability

the effects of public spending externalities abstract we conduct a positive analysis on the effects of externalities produced by government spending to this effect we estimate using u s data an rbc model with two salient features first we allow government consumption to directly affect the marginal utility of consumption second we allow public capital to shift the productivity of private factors we provide an identification analysis that supports the strategy adopted for estimating the parameters governing these two channels on one hand private and government consumption are robustly estimated to be substitute goods because of substitutability labor supply reacts little to a government consumption shock so the estimated output multiplier is much lower than in models with separabilities on the other hand our results point towards public investment being unproductive

the output effect of fiscal consolidation plans abstract we show that the correct experiment to evaluate the effects of a fiscal adjustment is the simulation of a multi year fiscal plan rather than of individual fiscal shocks simulation of fiscal plans adopted by 16 oecd countries over a 30 year period supports the hypothesis that the effects of consolidations depend on their design fiscal adjustments based upon spending cuts are much less costly in terms of output losses than tax based ones and have especially low output costs when they consist of permanent rather than stop and go changes in taxes and spending the difference between tax based and spending based adjustments appears not to be explained by accompanying policies including monetary policy it is mainly due to the different responses of business confidence and private investment
