income inequality in france 1901 1998 this paper uses data from income tax returns 1915 98 wage tax returns 1919 98 and inheritance tax returns 1902 94 in order to compute homogeneous yearly estimates of income wage and wealth inequality for twentieth century france the main conclusion is that the decline in income inequality that took place during the first half of the century was mostly accidental in france and possibly in a number of other countries as well wage inequality has been extremely stable in the long run and the secular decline in income inequality is for the most part a capital income phenomenon holders of large fortunes were badly hurt by major shocks during the 1914 45 period and they were never able to fully recover from these shocks probably because of the dynamic effects of progressive taxation on capital accumulation and pretax income inequality

vacancies unemployment and the phillips curve abstract the canonical new keynesian phillips curve has become a standard component of models designed for monetary policy analysis however in the basic new keynesian model there is no unemployment all variation in labor input occurs along the intensive hours margin and the driving variable for inflation depends on workers marginal rates of substitution between leisure and consumption in this paper we incorporate a theory of unemployment into the new keynesian theory of inflation and empirically test its implications for inflation dynamics we show how a traditional phillips curve linking inflation and unemployment can be derived and how the elasticity of inflation with respect to unemployment depends on structural characteristics of the labor market such as the matching technology that pairs vacancies with unemployed workers we estimate on us data the phillips curve generated by the model while we can reject the baseline new keynesian phillips curve in favor of the search frictions specification we show it is still too stylized to fully describe the dynamics of firms marginal costs

positively sloping marginal revenue ces utility and subsistence requirements the possibility that marginal revenue may possess a positive slope has long been recognized as important in her classic the economics of imperfect competition joan robinson 14 accorded considerable significance to the possibility and investigated it at length despite robinson s insights upward sloping marginal revenue functions remained largely a curiosity widely regarded as an overly stringent perversity unlikely to occur in reality considerable doubt was cast on this view when in 1980 a a walters 20 reported the presence of positively sloping marginal revenue in the pricing policies of the port of singapore the case for upward sloping marginal revenue was furthered by formby layson and smith s 8 straightforward demonstration that upward sloping marginal revenue schedules are very easily produced and can never be ruled out because simple parallel shifts in strictly convex demand and or rotations always transform demand schedules with downward sloping marginal revenue into ones with positively sloping schedules this strongly suggests that no theoretically reasonable restrictions can be placed on the behavior of marginal revenue because to do so would rule out such simple transformations as parallel shifts or rotations in demand such restrictions would be too stringent to be acceptable upward sloping marginal revenue has found important application in such diverse topics as catastrophe theory 3 third degree price discrimination 13 dual equilibria and monopolistic competition 11 specific taxes and quality 2 and international trade 7 2 the significance of non monotonic marginal revenue functions is further underscored by the fact that the presence of upward sloping marginal revenue significantly affects the sign of comparative static results for example see 18 260 15 16 2 a shortcoming of previous analyses lies in the fact that they draw conclusions from consideration of slope level and curvature of the demand schedule alone the behavior of marginal revenue derived directly from the more fundamental basis of utility theory has not been examined this paper takes up this question employing wold s theorem to analyze marginal revenue

the income and tax share of very high income households 1960 1995 this paper presents new information on the fraction of adjusted gross income and of wages and salaries that is reported by taxpayers in the top one half of one percent of the income distribution this corresponds to roughly five hundred thousand households in the late 1990s this paper relies on data from the treasury s individual income tax model for the period 1960 1995 the definition of adjusted gross income is standardized so that changes in the tax law do not affect the measured concentration of agi the results suggest that the share of agi reported by the highest income households increased significantly between the early 1980s and the mid 1990s with most of the increase taking place in the years immediately following the tax reform act of 1986 while we find some evidence of transitory changes in the concentration of income around major tax changes which may be the result of income retiming by high income taxpayers re timing does not seem to explain most of the changes since 1986 this abstract was borrowed from another version of this item

the international transmission of financial shocks the case of japan one of the more dramatic financial events of the late 1980s and early 1990s was the surge in japanese stock prices that was immediately followed by a very sharp decline of more than 50 percent while the unprecedented fluctuations in japanese stock prices were domestic financial shocks the unique institutional characteristics of the japanese economy produce a framework that is particularly suited to the transmission of such shocks to other countries through the behavior of the japanese banking system the large size of japanese bank lending operations in the united states enables us to use u s banking data to investigate the extent to which this domestic japanese financial shock was transmitted to the united states as well as to identify a supply shock to u s bank lending that is independent of u s loan demand we find that binding risk based capital requirements associated with the decline in the japanese stock market resulted in a decline in commercial lending by japanese banks in the united states that was both economically and statistically significant this finding has added importance given the severe real estate loan problems currently faced by japanese banks how japanese bank regulators decide to resolve these problems will have significant implications for credit availability in the united states as well as in other countries with a significant japanese bank presence

cartels and antitrust the role of fines in deterring violations at the margin the potential benefits of effective antitrust action include both increased economic efficiency through the expansion of output and improved equity through the redistribution of income from monopolies to consumers a large and growing literature is devoted to empirically testing and documenting the economic consequences of antitrust casebringing activity a second empirical literature is focused on the role which economic variables play in the determination of casebringing activity by the united states department of justice 2 what separates these two bodies of literature are the behavioral linkages between anti

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

economic welfare price and profit the deterrent effect of alternative antitrust regimes this paper critically examines the deterrent effect of price fixing statutes under alternative antitrust regimes a regime is defined by the litigation strategy which the antitrust agency employs in detecting cartels and in determining whether prosecution is warranted and by the basis upon which courts estimate damages the results of the analysis suggest that antitrust policy may actually induce cartels to further restrict output increasing welfare loss above the level imposed by an unthreatened perfect monopoly litigation strategy and damages should be founded upon consideration of welfare loss measures to avoid this possibility

the law of demand positive sloping marginal revenue and multiple profit equilibria this paper demonstrates that the conditions for a positively sloping marginal revenue curve are much less stringent than is generally recognized simple transformations of any well behaved convex demand function can easily result in a demand for which marginal revenue is positively sloping for this reason positively sloping marginal revenue functions must be considered whenever convex demand functions are analyzed the existence of positively sloping marginal revenue makes multiple profit equilibria for the firm a very real possibility

the deterrent effect of antitrust enforcement in this paper we formulate and test a model of collusive pricing in the presence of antitrust enforcement we show that a cartel s optimal price is likely to be neither the competitive price nor the price that the cartel would set in the absence of antitrust enforcement but rather an intermediate price that depends on the levels of antitrust enforcement efforts and penalties our empirical results reveal that increasing antitrust enforcement in the presence of a credible threat of large damage awards has the deterrent effect of reducing mark ups in the bread industry

what does a financial shock do first international evidence in this paper we attempt to evaluate the quantitative impact of financial shocks on key indicators of real activity and financial conditions we focus on financial shocks as they have received wide attention in the recent literature and in the policy debate after the global financial crisis we estimate a panel var for 21 advanced economies based on quarterly data between 1985 and 2011 where financial shocks are identified through sign restrictions we find robust evidence that financial shocks can be separately identified from other shock types and that they exert a significant influence on key macroeconomic variables such as gdp and particularly investment but it is unclear whether these shocks are demand or supply shocks from the standpoint of their macroeconomic impact the financial development and structure of a given country is found not to matter much for the intensity of the propagation of financial shocks moreover we generally find that these shocks play a role not only in crisis times but also in normal conditions finally we discuss the implications of our findings for monetary policy fabio fornari and livio stracca

house prices borrowing constraints and monetary policy in the business cycle i develop a general equilibrium model with sticky prices credit constraints nominal loans and asset prices changes in asset prices modify agents borrowing capacity through collateral value changes in nominal prices affect real repayments through debt deflation monetary policy shocks move asset and nominal prices in the same direction and are amplified and propagated over time the financial accelerator is not constant across shocks nominal debt stabilises supply shocks making the economy less volatile when the central bank controls the interest rate i discuss the role of equity debt indexation and household and firm leverage in the propagation mechanism finally i find that monetary policy should not target asset prices as a means of reducing output and inflation volatility

booms and banking crises banking crises are rare events that break out in the midst of credit intensive booms and bring about deep and long lasting recessions this paper presents a textbook dynamic stochastic general equilibrium model to explain these phenomena the model features a nontrivial banking sector where bank heterogeneity gives rise to an interbank market moral hazard and asymmetric information in this market may lead to sudden market freezes banking crises credit crunches and severe financial recessions those recessions follow credit booms and are not necessarily triggered by large exogenous adverse shocks

bank leverage cycles and the external finance premium by combining the approaches of gertler and karadi 2011 and bernanke et al 1999 i develop a dsge model with leverage constraints both in the banking and in the non financial firm sector i calibrate this full model to us data in a world with only a monetary policy and a productivity shock the full model matches the relative volatility of the external finance premium while a bgg model generates too low volatility the full model also matches the procyclicality of bank leverage unlike the gk model for a reasonably calibrated combination shocks to the net worth of banks and non financial firms the model reproduces a substantial share of the contraction increase of investment the external finance premium observed during the great recession

the effect of marginal tax rates on taxable income a panel study of the 1986 tax reform act this paper uses a treasury department panel of more than 4 000 taxpayers to estimate the sensitivity of taxable income to changes in tax rates on the basis of a comparison of the tax returns of the same individual taxpayers before and after the 1986 tax reform the analysis emphasizes that the response of taxable income involves much more than a change in the traditional measures of labor supply the evidence shows an elasticity of taxable income with respect to the marginal net of tax rate that is at least one and could be substantially higher the implications for recent tax rate changes are discussed

trend inflation and firms price setting rotemberg versus calvo we compare the calvo and rotemberg price setting mechanisms in a new keynesian model with trend inflation we show that the long run relationship between inflation and output is positive in rotemberg and negative in calvo the dynamics of the two models differ even to a first order approximation positive trend inflation enlarges the determinacy region in the rotemberg model whereas it shrinks it in the calvo model the responses of output and inflation to technology shocks are amplified by trend inflation in calvo whereas they are dampened in rotemberg the two models imply differing non linear adjustments after a disinflation

strategic and deterrent pricing responses to antitrust investigations abstract this paper examines the issue of the effects of antitrust on pricing through two empirical studies the first analyzes time series of prices in five industries involved in antitrust cases to determine whether the various stages of the antitrust process influenced pricing behavior some evidence of a deterrent effect is found with real prices lower than their pre investigation level following the conclusion of the case a major part of the pricing reaction occurs prior to the filing of formal charges the second study provides additional evidence of the existence of such a strategic reaction to the onset of investigation through an examination of prices in 23 industries investigated but not charged with price fixing

what happens when you tax the rich evidence from executive compensation this paper examines the responsiveness of taxable income to changes in marginal tax rates using detailed compensation data on several thousand corporate executives from 1991 to 1995 the data confirm that the higher marginal rates of 1993 led to a significant decline in taxable income indeed this small group of executives may account for as much as 20 percent of the aggregate change in wage and salary income for approximately the one million richest taxpayers over this time period one person alone can account for more than 2 percent the decline however is almost entirely a short run shift in the timing of compensation rather than a permanent reduction in taxable income the short run elasticity of taxable income with respect to the net of tax share exceeds one in this sample but the elasticity after one year is at most 0 4 and probably closer to zero breaking out the tax responsiveness of different types of compensation shows that the large short run responses come almost entirely from a large inc

innocent bystanders monetary policy and inequality abstract we study the effects of monetary policy shocks on and their historical contribution to consumption and income inequality in the united states since 1980 as measured by the consumer expenditure survey contractionary monetary policy systematically increases inequality in labor earnings total income consumption and total expenditures furthermore monetary policy shocks account for a non trivial component of the historical cyclical variation in income and consumption inequality using detailed micro level data on income and consumption we document some of the different channels via which monetary policy shocks affect inequality as well as how these channels depend on the nature of the change in monetary policy

firm heterogeneity in capital labour ratios and wage inequality author s leonardi marco abstract this paper documents the increasing dispersion of capital labor ratios across firms in the us and provides some empirical evidence of a positive correlation at the two digit industry level between the dispersion of capital labor ratios across firms and residual wage inequality to explain this empirical fact the paper adopts a search model where firms differ in their optimal capital investment the exogenous decline in the relative price of equipment capital makes the distributions of capital labor ratios more dispersed in a frictional labor market this force generates wage dispersion among identical workers ols estimates of the relationship between capital dispersion and the relative price of equipment capital support the main hypothesis of the model

banks leverage behaviour in a two agent new keynesian model abstract we study the distributive effects of a negative shock to banks assets in a saver capitalist model we analyze how this kind of heterogeneity affects macroeconomic variables and the distribution between savers and capitalists through banks leverage procyclicality the distributive effects are non favourable to savers and long lasting lower risk aversion of capitalists strengthens and lengthens the procyclicality of leverage leading to a lower decrease of savers income and consumption whilst stricter regulatory requirements are favourable to savers a tougher inflation targeting is unfavourable to savers the model is robust to the combined introduction of labour market frictions and hysteresis which together generate an amplification and lengthening of the recessionary and distributive effects unfavourable to savers

optimal fiscal and monetary policy under sticky prices this paper studies optimal fiscal and monetary policy under sticky product prices the theoretical framework is a stochastic production economy without capital the government finances an exogenous stream of purchases by levying distortionary income taxes printing money and issuing one period nominally risk free bonds the main findings of the paper are first for a miniscule degree of price stickiness i e many times below available empirical estimates the optimal volatility of inflation is near zero this result stands in stark contrast with the high volatility of inflation implied by the ramsey allocation when prices are flexible the finding is in line with a recent body of work on optimal monetary policy under nominal rigidities that ignores the role of optimal fiscal policy second even small deviations from full price flexibility induce near random walk behavior in government debt and tax rates third sluggish price adjustment raises the average nominal interest rate above the one called for by the friedman rule finally an interest rate feedback rule whereby the nominal interest rate depends on inflation and output fits well the data emanating from the ramsey economy however the fitted rule is not of the taylor type for the implied inflation coefficient is less than one and close to zero and the output coefficient is negative jel classification e52 e61 e63
