estimates of effective marginal tax rates on factor incomes this chapter describes a method of calculating summary measures of effective factor income tax rates in the united states using readily available data the numbers resulting from application of this method in a study are reported in the chapter and some of their possible uses are discussed the estimated factor income tax rates behave over time in a manner quite consistent with the behavior of other broad measures of federal tax policy the postwar movement in the tax rate on income from labor relative to that on income from capital or more accurately the relevant components of these tax rates provides suggestive support for the miller scholes hypothesis that the federal personal income tax has been moving in the direction of a pure consumption tax the tax rates reported in the chapter are consistent with other studies that show a decrease since the 1950s in rates of taxation at the corporate level of income from corporate held capital they are also consistent with the view that rates of taxation of such income at the noncorporate level have risen but not quite sufficiently to offset the decline in the corporate tax burden

spurious volatility in historical unemployment data this paper shows that the stabilization of the unemployment rate between the pre 1930 and post 1948 eras is an artifact of improvements in data collection procedures prewar methods are used to construct postwar unemployment data that are consistent with the historical data the constructed postwar series is nearly as volatile as the pre 1930 unemployment data the constructed postwar data are systematically more volatile than the actual postwar data because the cyclical behavior of the labor force and productivity are misspecified in the construction procedures the relationship between the actual and constructed postwar unemployment series is used to construct new historical data

dynamic scoring alternative financing schemes abstract neoclassical growth models predict that reductions in capital or labor income tax rates are expansionary when lump sum transfers are used to balance the government budget this paper explores the consequences of bond financed tax reductions that bring forth a range of possible offsetting policies including future government consumption capital tax rates or labor tax rates through the resulting intertemporal distortions current tax cuts can be expansionary or contractionary the paper also finds that more aggressive responses of offsetting policies to debt engender less debt accumulation and less costly tax cuts

alternative maximum likelihood estimation of structural vector autoregressive models partially identified with short run restrictions this paper presents an alternative maximum likelihood estimation method for partially identified vector autoregressive models this method might be especially useful to handle very large systems of variables by reducing the dimension of the likelihood space as an application we consider an open economy model to investigate the effects of monetary policy on exchange rates and term structures we find that exchange rates tend to overshoot and term structures have hump shaped responses to monetary policy shocks

voter turnout in the industrial democracies during the 1980s there are two contending accounts of cross national variation in voter turnout rates one emphasizes the role of institutions and electoral attributes whereas the other stresses cultural and historical factors the authors evaluate the merits of these two arguments they first apply the model developed by r w jackman to turnout rates during the 1980s expanding the sample of industrial states to include three newer democracies with recent authoritarian histories greece portugal and spain they then examine the potential impact of cultural variables on voter turnout rates the authors conclude that the institutional argument outperforms the cultural account of conventional political participation

annual hours and weeks in a life cycle labor supply model canadian evidence on male behavior estimates of the intertemporal labor supply behavior of males in canada using micro data are reported individuals make the intertemporal labor supply decision on the basis of annual hours and weeks precision of the parameter estimates is improved by using tenure variables as instruments for the wage further the age and tenure variables are allowed to have taste parameters in the structural equations the evidence suggests that this is required only for the two age variables elasticity evidence suggests that evolutionary changes in the wage cause changes in the number of weeks with the elasticity being 0 6 and statistically significant

districting and government overspending theories of government spending driven by a common pool problem in the fiscal revenues pool predict that greater districting of a political jurisdiction raises the scale of government this paper presents evidence on this and related predictions from a cross section of city governments in the united states the main finding is that when other plausible determinants of government spending are controlled for greater districting leads to a considerably greater scale of government activity the results also show that at large electoral systems do not and forms of government that concentrate powers in the office of the executive do break this relationship

clientelism and vote buying lessons from field experiments in african elections electoral clientelism and vote buying are widely perceived as major obstacles to economic development this is because they may limit the provision of public goods in this paper we review the literature on clientelism and vote buying and propose the use of field experiments to evaluate empirically the consequences of these phenomena we provide an overview discuss implementation and interpret the main results of recent field experiments conducted by the authors in west african countries clientelism and vote buying seem to be effective and to enjoy widespread electoral support the results suggest that increased access to information and political participation by women may limit clientelism in addition voter education campaigns may undermine the effects of vote buying on voting behaviour we argue that our findings may inform the design of development aid interventions as a way effectively to increase public good political accountability we also discuss directions for fruitful future research copyright 2009 oxford university press

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

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

indeterminacy and stabilization policy abstract it has been shown that a one sector real business cycle model with sufficient increasing returns in production may possess an indeterminate steady state that can be exploited to generate business cycles driven by animal spirits of agents this paper shows how an income tax schedule that exhibits a progressivity feature can ensure saddle path stability in such a framework and thereby stabilize the economy against sunspot fluctuations conversely an economy with a flat or regressive tax schedule is more susceptible to indeterminacy journal of economic literature classification numbers e32 e62

business cycles with distorting taxes and disaggregated capital markets abstract this paper studies a neoclassical growth model to examine the linkages between distorting corporate and personal taxes and cyclical movements of aggregates such as investments in equipment and structures suppose tax variables vary stochastically and annually we solve quarterly individual and aggregate decision rules by recursive methods and quantify the dynamic impacts on aggregates from unit changes in tax structures and individual and joint tax specifications the findings suggest that corporate income tax is the major factor leading to substantial tax effects on business cycles moreover the impact of investment tax credit for equipment on disaggregated investments is equally significant

the output and welfare effects of government spending shocks over the business cycle how does the output response to a change in government spending vary over the business cycle what are the welfare eects of spending shocks this paper studies the state dependence of the output and welfare eects of shocks to government purchases in a dsge model with real and nominal frictions and a rich scal nancing structure both the output multiplier the change in output for a one dollar change in government spending and the welfare multiplier the consumption equivalent change in welfare for the same change in spending move signicantly across states but tend to co move negatively with one another in an historical simulation the output multiplier is countercyclical correlation with detrended output of 0 4 and strongly negatively correlated with the welfare multiplier correlation between multipliers of 0 9

marginal tax rates and income new time series evidence this paper estimates the dynamic effects of marginal tax rate changes on income reported on tax returns in the united states over the 1950 2010 period after isolating exogenous variation in average marginal tax rates in structural vector autoregressions using a narrative identification approach i find large positive effects of tax cuts in the top 1 of the income distribution in contrast to earlier findings based on tax return data i also find large effects in other income percentile brackets a hypothetical tax reform cutting marginal rates only for the top 1 leads to sizeable increases in top 1 incomes and has a positive effect on real gdp there are also spillover effects to incomes outside of the top 1 but top marginal rate cuts lead to greater inequality in pre tax incomes

tax disturbances and real economic activity in the postwar united states abstract this paper investigates the macroeconomic effects of cyclical fluctuations in marginal tax rates it finds that systematically including tax variables in a standard real business cycle model substantially improves the model s ability to reproduce basic facts about postwar u s business cycle fluctuations in particular modeling fluctuations in personal and corporate income tax rates increases the model s predicted relative variability of hours and decreases its predicted correlation between hours and average productivity fluctuations in tax rates produce large substitution effects that alter the leisure labor supply decision

optimal fiscal policy in a business cycle model this paper develops the quantitative implications of optimal fiscal policy in a business cycle model in a stationary equilibrium the ex ante tax rate on capital income is approximately zero there is an equivalence class of ex post capital income tax rates and bond policies that support a given allocation within this class the optimal ex post capital tax rates can range from close to independently and identically distributed to close to a random walk the tax rate on labor income fluctuates very little and inherits the persistence properties of the exogenous shocks thus there is no presumption that optimal labor tax rates follow a random walk most of the welfare gains realized by switching from a tax system like that of the united states to the ramsey system come from an initial period of high taxation on capital income

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

great recession slow recovery and muted fiscal policies in the us this paper reconsiders the role of macroeconomic shocks and policies in determining the great recession and the subsequent recovery in the us the great recession was mainly caused by a large demand shock and by the zlb on the interest rate policy in contrast with previous findings the subsequent jobless recovery is explained by the zlb effect we estimate a fraction of non ricardian households which is close to 50 and obtain comparatively large fiscal multipliers however we cannot detect a significant contribution of fiscal policies in stabilizing the us economy for instance the 2007 2009 large increase in expenditure to gdp ratios was apparently determined by the adverse non policy shocks that caused the recession

executive elections in the arab world when and how do they matter although elections loom large in the study of nondemocracies scholars continue debating what function those elections play this article sets evidence from the arab world in a global context to evaluate three theorized roles for elections safety valve patronage network and performance ritual executive elections in the middle east and north africa remain less common and less competitive than polls in sub saharan africa and asia this profile is largely consistent with the observable implications of leading theories the data though also show theoretically rich differences although levels of competition and participation in yemen tunisia and algeria fit expectations about elections being safety valves or political spectacles egypt s presidential election stands apart with exceptionally meager public involvement in such circumstances where competition and turnout are both unusually low other social and political phenomena may matter more than elections for regime survival resource distributio

macroeconomic fluctuations and the allocation of time what are the fundamental driving forces of macroeconomic fluctuations in particular why do people spend more time working in booms and less in recessions these are basic questions of macroeconomics recent thinking has emphasized technology shifts preference shifts and changes in government purchases as likely driving forces it is useful to distinguish atemporal and intertemporal effects of the driving forces under standard assumptions the technology shift has no effect through atemporal channels because income and substitution effects exactly offset a straightforward decomposition of movements of employment attributes most of them to the atemporal effects of preference shifts

have postwar economic fluctuations been stabilized previous investigations of whether the volatility of the u s economy diminished after world war ii have been inconclusive because of questionable prewar macroeconomic aggregates we examine more broadly the hypothesis of the stabilization of the postwar economy by focusing on the duration of business cycles rather than their amplitude in the process we avoid the debate about the quality of prewar aggregates using distribution free statistics we find clear evidence of postwar duration stabilization in terms of a shift toward longer expansions and shorter contractions moreover we find no shift in whole cycle durations which suggests a reallocation of the business cycle away from contraction and toward expansion

on credit frictions as labor income taxation abstract this paper suggests that a model in which firms face credit constraints on hiring labor can explain both the behavior of the labor wedge and the jobless recoveries phenomenon of the last three recessions using the corporate credit spread as a measure of firms credit conditions i show that the jobless recoveries of the u s economy from the last three recessions were associated with slow declines in the spread following those recessions the credit conditions of firms thus were important in shaping the labor market recoveries of the last two decades

the size and scope of government comparative politics with rational politicians we try to demonstrate how economists may engage in research on comparative politics relating the size and composition of government spending to the political system a downsian model of electoral competition and forward looking voting indicates that majoritarian as opposed to proportional elections increase competition between parties by focusing it into some key marginal districts this leads to less public goods less rents for politicians more redistribution and larger government a model of legislative bargaining and backward looking voting indicates that presidential as opposed to parliamentary regimes increase competition between both politicians and voters this leads to less public goods less rents for politicians less redistribution and smaller government we confront these predictions with cross country data from around 1990 controlling for economic and social determinants of government spending we nd strong and robust support for the prediction that the size of government is smaller under presidential regimes and weaker support for the prediction that majoritarian elections are associated with less public goods

balanced budget rules distortionary taxes and aggregate instability a traditional argument against a balanced budget fiscal policy rule is that it amplifies business cycles by stimulating aggregate demand during booms via tax cuts and higher public expenditures and by reducing demand during recessions through a corresponding fiscal contraction this paper suggests an additional source of instability that may arise from this type of fiscal policy rule it shows that within the standard neoclassical growth model a balanced budget rule can make expectations of higher tax rates self fulfilling if the fiscal authority relies heavily on changes in labor income taxes to eliminate short run fiscal imbalances calibrated versions of the model show that indeterminacy occurs for income tax rates that are empirically plausible for the u s economy and other group of seven countries

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

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

measures of per capita hours and their implications for the technology hours debate structural vector autoregressions give conflicting results on the effects of technology shocks on hours the results depend crucially on the assumed data generating process for hours per capita we show that the standard measure of hours per capita and productivity have significant low frequency movements that are the source of the conflicting results hodrick prescott hp filtered hours per capita produce results consistent with those obtained when hours are assumed to have a unit root we show that important sources of the low frequency movements in the standard measure are sectoral shifts in hours and the changing age composition of the working age population when we control for these low frequency components to determine the effect of technology shocks on hours using long run restrictions we get one consistent answer hours decline in the short run in response to a positive technology shock we further extend the analysis by examining the effects of demographic controls on the impulse responses to investment specific technology shocks our results are less conclusive

fiscal policy in the aftermath of 9 11 this paper investigates the nature of u s fiscal policy in the aftermath of 9 11 we argue that the recent declines in the government surplus and tax rates cannot be accounted for by either the state of the u s economy as of 9 11 or as the typical response of fiscal policy to a large exogenous rise in military expenditures our evidence suggests that had tax rates responded in the way they normally do to a large fiscal shock aggregate output would have been lower and the surplus would not have changed by much our results do not bear directly on the desirability of the decline in tax rates or the surplus after 9 11

effective tax rates in macroeconomics cross country estimates of tax rates on factor incomes and consumption abstract this paper proposes a method for computing tax rates using national accounts and revenue statistics using this method we construct time series of tax rates for large industrial countries the method identifies the revenue raised by different taxes at the general government level and defines aggregate measures of the corresponding tax bases this method yields estimates of effective tax rates on factor incomes and consumption consistent with the tax distortions faced by a representative agent in a general equilibrium framework these tax rates compare favorably with existing estimates of marginal tax rates and highlight important international differences in tax policy

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

optimal fiscal policy with labor selection this paper characterizes long run and short run optimal scal policy in the labor selection framework quantitatively the time series volatility of the labor income tax rate is orders of magnitude larger than the tax smoothing results based on walrasian labor markets but is a few times smaller than the results based on search and matching labor markets to understand these results in terms of model primitives we develop a welfare relevant analytic concept of externalities for the selection model which we label tightness this concept of tightness is the source of the decentralized economy s inecient cross sectional wage premia between the average newly hired worker and the marginal newly hired worker compared to the traditional concept of labor market tightness in the search and matching literature this new concept of tightness plays a highly similar role and like in the matching model is crucial for understanding eciency and optimal policy

can long run restrictions identify technology shocks gali s innovative approach of imposing long run restrictions on a vector autoregression var to identify the effects of a technology shock has become widely utilized in this paper we investigate its reliability through monte carlo simulations using calibrated business cycle models overall gali s methodology appears to be fruitful the impulse responses derived from the artificial data generally have the same sign and qualitative pattern as the true responses and the approach can be informative in discriminating between alternative models however our results reveal some important quantitative shortcomings including considerable estimation uncertainty about the impact of technology shocks on macroeconomic variables more generally the conditions under which the methodology performs well appear considerably more restrictive than implied by the key identifying assumption this underscores the importance of using economic models to guide in the implementation of the approach in interpreting the results and in assessing its limitations jel c32 e32 o33

using stock returns to identify government spending shocks this article explores a new approach to identifying government spending shocks which avoids many of the shortcomings of existing approaches the new approach is to identify government spending shocks with statistical innovations to the accumulated excess returns of large us military contractors this strategy is used to estimate the dynamic responses of output hours consumption and real wages to a government spending shock we find that positive government spending shocks are associated with increases in output hours and consumption real wages initially decline after a government spending shock and then rise after a year we estimate the government spending multiplier associated with increases in military spending to be about 1 5 over a horizon of 5 years

the analytics of svars a unified framework to measure fiscal multipliers ticities implied by the identification schemes generate a large dispersion in the estimates of tax and spending multipliers second i estimate fiscal multipliers consistent with prior distributions of the elasticities computed by a variety of empirical strategies and by employing a simple dynamic stochastic general equilibrium model i document three findings for the u s for the period 1947 2010 first the impact tax multiplier is close to 0 second the impact spending multiplier ranges between 0 35 and 1 third there is a large uncertainty in the estimates of fiscal multipliers at longer horizons yet the probability that the spending multiplier is larger than the tax multiplier is above 0 65 for up to three years after policy interventions

quantifying tax effects under policy foresight abstract studies of tax effects make the conventional information assumption that changes in period t taxes become known at t legislative lags however imply that news arrives before tax changes take place under policy foreknowledge the conventional information structure is therefore misspecified simulations of a standard neoclassical growth model suggest that foresight of only one quarter can distort substantially the estimates of tax effects obtained under the no foresight assumption also it is crucial to model capital and labor taxes separately anticipated changes in these two tax policies have opposite effects on consumption investment labor and output before policy realization

countercyclical taxes in a monopolistically competitive environment in the context of a neoclassical growth model with monopolistic competition this paper studies the stabilizing effects of countercyclical tax policy when the income tax rate has an additional role of financing government budget deficits consistent with the conventional wisdom countercyclical taxes generally reduce aggregate volatility unless the fiscal response to debt accumulation is weak the presence of monopoly power enhances these effects even when automatic stabilizers successfully stabilize business cycle fluctuations countercyclical taxes are welfare inferior due to reduced precautionary saving motives while if the fiscal response to debt is weak and countercyclical tax policy destabilizing the increased precautionary saving motive is not welfare enhancing as the asset accumulated is government debt rather than capital these results are generally robust nominal inertia may however dominate the precautionary saving mechanism

tax analysis in a real business cycle model on measuring harberger triangles and okun gaps abstract a tax distorted real business cycle model is parameterized calibrated and solved numerically in an attempt to measure the size of harberger triangles relative to okun gaps in particular the model constructed is used to study quantitatively the impact of various distortional government tax and subsidy schemes it is shown that the government can use tax policy to stabilize cyclical fluctuations and this is done for the economy being studied the benefits of implementing such a stabilization policy are calculated and compared with the size of the welfare gains realized from reducing various tax distortions

the determinants of uk business cycles this paper considers the causes of post war uk business cycles using an extended stochastic growth model we construct estimates of productivity and preference shocks both of which are highly persistent volatile and potentially capable of explaining uk business cycles we find the productivity term is the dominant explanation of uk output fluctuations but our estimated preference shift is crucial in understanding employment movements a variety of granger causality tests establish whether these productivity and preference terms are unpredictable and so can be potentially considered as the cause of uk business cycles or whether they are themselves granger caused by other variables the aim of business cycle theory is to identify the causes of business cycles and outline the various propagation mechanisms through which these produce cyclical fluctuations the purpose of this paper is to study the former using uk data we investigate the main sources of uk post war business cycles our aim in doing so is to discriminate between competing theories of the business cycle as well as to increase our understanding of particular episodes of uk post war economic history to achieve this aim we focus on two fundamental sources of business cycle fluctuations productivity shocks and a preference shift or more generally a supply and demand shock we choose these because i they can be easily calculated using only published data avoiding the need for any econometric identification assumptions ii they represent the simplest extension to the neoclassical stochastic growth model which can explain observed uk business cycle patterns they therefore form a natural benchmark with which to assess prescott s 1986 claim that this model can account for both growth and business cycles however while our main focus is on these two shocks our methodology is broad enough to allow for a wide range of potential causes of uk business cycles in section 1 of the paper we outline some stylised facts of the uk business cycle and motivate more rigorously our focus on productivity and preference shocks in section 2 we provide estimates of these shocks discuss their univariate properties and examine their correlation with key business cycle variables we find both shocks to be very volatile and persistent with the productivity variable accounting for a large proportion of output fluctuations and preference shifts more important in explaining employment movements simulations show that in combination with a neoclassical growth model these shocks are capable of matching uk business cycles however if

chaos sunspots and automatic stabilizers abstract we consider a real business cycle model with an externality in production depending on parameter values the model has sunspot equilibria cyclical and chaotic equilibria and equilibria with deterministic or stochastic regime switching we study the implications of this model environment for automatic stabilizer tax systems stabilization is desirable because the efficient allocations are characterized by constant employment and output growth we identify an automatic stabilizer income tax subsidy schedule with two properties i it specifies the tax rate to be an increasing function of aggregate employment and ii earnings are subsidized when aggregate employment is at its efficient level the first feature eliminates inefficient fluctuating equilibria while the second induces agents to internalize the externality

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

fiscal news and macroeconomic volatility abstract this paper analyzes the contribution of anticipated capital and labor tax shocks to business cycle volatility in an estimated new keynesian business cycle model while fiscal policy accounts for about 15 of output variance at business cycle frequencies this mostly derives from anticipated government spending shocks tax shocks both anticipated and unanticipated contribute little to the fluctuations of real variables however anticipated capital tax shocks do explain a sizable part of inflation fluctuations accounting for up to 12 of its variance in line with earlier studies news shocks in total account for about 50 of output variance further decomposing this news effect we find permanent total factor productivity news shocks to be most important when looking at the federal level instead of total government the importance of anticipated tax and spending shocks significantly increases suggesting that fiscal policy at the subnational level typically counteracts the effects of federal fiscal policy shocks

factor hoarding and the propagation of business cycles shocks this paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle to this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding we find that variable capital utilization rates substantially magnify and propagate the impact of shocks to agents environments the strength of these propagation effects is evident in the dynamic response functions of various economy wide aggregates to shocks in agents environments in the statistics that we construct to summarize the strength of the propagation mechanisms in the model and in the volatility of exogenous technology shocks needed to explain the observed variability in aggregate u s output other authors have argued that standard real business cycle rbc models fail to account for certain features of the data because they do not embody quantitatively important propagation mechanisms these features include the observed positive serial correlation in the growth rate of output the shape of the spectrum of the growth rate of real output and the correlation between the forecastable component of real output and various other economic aggregates allowing for variable capital utilization rates substantially improves the ability of the model to account for these features of the data

explaining business cycles a multiple shock approach abstract aiyagari 1992 and prescott 1986 1991 claim that a large fraction of the variance of united states quarterly detrended real gnp is attributable to an unobservable shock to total factor productivity this paper argues that the importance of a productivity shock in explaining the variance of output is fundamentally indeterminate any model that is in accord with the several time series that make up united states macroeconomic data must feature multiple shocks that are correlated at all leads and lags sorting out the separate effects of these various shocks on a single variable such as real gnp is impossible we illustrate this argument using a multiple shock version of the king plosser rebelo 1988 benchmark real business cycle model

comparative politics and public finance we propose a model with micropolitical foundations to contrast different political regimes compared to a parliamentary regime the institutions of a presidential congressional regime produce fewer incentives for legislative cohesion but more separation of powers these differences are reflected in the size and composition of government spending a parliamentary regime has redistribution toward a majority less underprovision of public goods and more rents to politicians a presidential congressional regime has redistribution toward powerful minorities more underprovision of public goods but less rents to politicians the size of government is smaller under a presidential regime this last prediction is consistent with cross country data

stochastic depreciation and the business cycle the authors study a version of the neoclassical growth model in which shocks to both aggregate productivity and the depreciation of capital generate fluctuations around the steady state growth path depreciation shocks induce an inverse comovement between average labor productivity and hours worked when the model is calibrated to u s data it generates a correlation between productivity and hours which is significantly closer to the observed value than that of standard real business cycle models furthermore the addition of depreciation shocks does not cause a deterioration of the predictions of the model concerning other comovements copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the fiscal state dependent effects of capital income tax cuts abstract using the post wwii data of u s federal corporate income tax changes within a smooth transition var this paper finds that the output effect of capital income tax cuts is government debt dependent it is less expansionary when debt is high than when it is low to explore the mechanisms that can drive this fiscal state dependent tax effect the paper uses a dsge model with regime switching fiscal policy and finds that a capital income tax cut is stimulative to the extent that it is unlikely to result in a future fiscal adjustment as government debt increases to a sufficiently high level the probability of future fiscal adjustments starts rising and the expansionary effects of a capital income tax cut can diminish substantially whether the expected adjustments are through a policy reversal or a consumption tax increase also a capital income tax cut need not always have large revenue feedback effects as suggested in the literature

what does a technology shock do a var analysis with model based sign restrictions abstract this paper estimates the effects of technology shocks in var models of the u s identified by imposing restrictions on the sign of impulse responses these restrictions are consistent with the implications of a popular class of dsge models with both real and nominal frictions and with sufficiently wide ranges for their parameters this identification strategy thus substitutes theoretically motivated restrictions for the atheoretical assumptions on the time series properties of the data that are key to long run restrictions stochastic technology improvements persistently increase real wages consumption investment and output in the data hours worked are very likely to increase displaying a hump shaped pattern contrary to most of the related var evidence results are not sensitive to a number of specification assumptions including those on the stationarity properties of variables

the choice of municipal government structure and public expenditures numerous empirical studies have attempted to measure the effect of varying government structures on public expenditures i argue that these prior may have produced biased estimates as they are predicated on the assumption that government structures are exogenous

labor hoarding and the business cycle this paper investigates the sensitivity of solow residual based measures of technology shocks to labor hoarding behavior using a structural model of labor hoarding and the identifying restriction that innovations to technology shocks are orthogonal to innovations in government consumption we estimate the fraction of the variability of the solow residual that is due to technology shocks our results support the view that a significant proportion of movements in the solow residual are artifacts of labor hoarding behavior specifically we estimate that the variance of innovations to technology is roughly 50 percent less than that implied by standard real business cycle models in addition our results suggest that existing real business cycle studies substantially overstate the extent to which technology shocks account for the variability of postwar aggregate u s output

on measuring the welfare cost of business cycles lucas 1987 argues that the gain from eliminating aggregate fluctuations is trivial following lucas a number of researchers have altered assumptions on preferences and found that the gain from eliminating business cycles are potentially very large however in these exercises little discipline is placed on preference parameters this paper estimates the welfare cost of business cycles allowing for potential time non separabilities in preferences where discipline is placed on the choice of preference parameters by requiring that the preferences be consistent with observed fluctuations in a model of business cycles that is a theoretical real business cycle world is constructed and the representative agent is then placed in this world the agent responds optimally to exogenous shocks given the frictions in the economy the agent s preference parameters along with other structural parameters are estimated using a bayesian procedure involving markov chain monte carlo methods two main results emerge from the paper first the form for the time non separability estimated in this paper is very different than the forms suggested and used elsewhere in the literature second the welfare cost of business cycles is close to lucas s estimate

what are the effects of fiscal policy shocks we propose and apply a new approach for analyzing the effects of fiscal policy using vector autoregressions specifically we use sign restrictions to identify a government revenue shock as well as a government spending shock while controlling for a generic business cycle shock and a monetary policy shock we explicitly allow for the possibility of announcement effects i e that a current fiscal policy shock changes fiscal policy variables in the future but not at present we construct the impulse responses to three linear combinations of these fiscal shocks corresponding to the three scenarios of deficit spending deficit financed tax cuts and a balanced budget spending expansion we apply the method to us quarterly data from 1955 to 2000 we find that deficit financed tax cuts work best among these three scenarios to improve gdp with a maximal present value multiplier of five dollars of total additional gdp per each dollar of the total cut in government revenue 5 years after the shock copyright 2009 john wiley sons ltd

elections in the arab world why do citizens turn out this article examines the determinants of voting in competitive authoritarian regimes in the arab world in contrast to scholars who view elections in the arab world purely as patronage contests we argue that citizens also care about policy outputs and use turnout as a way to signal their approval or disapproval with the regime we draw on the literature on economic voting in democratic regimes to develop an argument about economic voting under authoritarian conditions and we propose a mediation model to get at the mechanisms of economic voting we test our argument with original data based on surveys conducted in seven arab countries between 2006 and 2009 our results show that although patronage helps to explain turnout especially among high income citizens policy outcomes are also important in the calculus of voting most voters turn out to vote to show approval of the regime and its economic performance

public spending endogenous growth and endogenous fluctuations abstract this article studies indeterminacy and endogenous growth in a simple one sector model of capital accumulation endowed with inelastic labor supply in which the presence of public goods creates positive externalities both in the production and the consumption sectors because of increasing returns in the utility function the economy exhibits not only perpetual growth but also indeterminacy and therefore endogenous stochastic growth fluctuations the possibility of sunspot equilibrium growth paths is shown to be consistent with plausible parameter values journal of economic literatureclassification numbers e32 o41 h40

has fiscal policy helped stabilize the postwar u s economy abstract in this paper i consider whether postwar fiscal policy has helped stabilize the u s economy i do this by adding to the stochastic growth model fiscal policy feedback rules estimated from postwar data these rules allow fiscal policies to respond to current and lagged output and labor hours i use the estimated policy rules to see if postwar fiscal policy reduces output volatility and or lengthens expansions and shortens recessions i find that fiscal policy in general provides little stability on either count i also find that the endogenous feedback links by themselves can provide some stabilization

city level analysis of the effect of political regimes on public good provision this paper uses u s city level data on five public expenditure categories to test empirically whether the form of local government affects the amount of public good provision this also serves as an empirical test of a theory of national politics that predicts higher provision of public good in parliamentary than in presidential regimes the robust results indicate that at the city level the mayor council form of government provides significantly more public good than the council manager form of government for two of the public expenditure categories and at the national level presidential regimes provide more public good than do parliamentary regimes

regional effects of federal tax shocks this article studies the effects of federal tax changes on u s state level income utilizing an exogenous tax shock series recently proposed in the literature we find considerable variation in how federal tax changes affect regional income estimated state income multipliers range between 0 2 in utah and 3 7 in hawaii analyzing the determinants of differences in regional tax multipliers suggests that size and composition of the state tax base help explain the observed heterogeneity in the transmission of federal tax policy

the determination of local public expenditures and the principal and agent relation a case study the principal and agent relationship is important in the public sector there elected or appointed representatives act on behalf of the citizens of their jurisdictions this paper examines the importance of the budget referendum which allows the principals to approve or disapprove the proposal of a set of agents in the context of local public expenditure decisions we test the null hypothesis that the institution of referendum when compared to a nonreferendum institution does not lead to significantly different expenditure behavior

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

business cycle durations and postwar stabilization of the u s economy average postwar expansions are twice as long as prewar expansions and contractions are one half as long this paper investigates three possible explanations the first explanation is that shocks to the economy have been smaller in the postwar period the second explanation is that the composition of output has shifted from very cyclical sectors to less cyclical sectors the third explanation is that the apparent stabilization is largely spurious and is caused by differences in the way that prewar and postwar business cycle reference dates were chosen by the national bureau of economic research the evidence presented in this paper favors this third explanation copyright 1994 by american economic association

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

clientelism and voting behavior evidence from a field experiment in benin the author conducted a field experiment in benin to investigate the impact of clientelism on voting behavior in collaboration with four political parties involved in the 2001 presidential elections clientelist and broad public policy platforms were designed and run in twenty randomly selected villages of an average of 756 registered voters using the survey data collected after the elections the author estimated the effect of each type of message by comparing voting behavior in the villages exposed to clientelism or public policy messages treatment groups with voting behavior in the other villages control groups the author found that clientelist messages have positive and significant effect in all regions and for all types of candidates the author also found that public policy messages have a positive and significant effect in the south but a negative and significant effect in the north in addition public policy messages seem to hurt incumbents as well as regional candidates finally the evidence indicates that female voters tend to have stronger preference for public policy platforms than male voters

the dynamic effects of firm level borrowing constraints in this paper i develop a detailed dynamic model of firm behavior in order to see whether financial constraints and endogenous exit are important propagation mechanisms to do this i construct an economy where firms face financial constraints fixed costs and persistent idiosyncratic shocks using numerical methods i analyzehowa large collection of these firmsresponds to aggregate productivity shocks a common result is that financial constraints tend to dampen the economy s initial response to aggregate productivity shocks but equity accumulation and exit dynamics amplify the longer term response the relative sizes of these two effects however are sensitive to firms environments

stochastic fiscal policy and the swedish business cycle in this paper we show that fluctuations in distortive taxes can account for some of the key features of the swedish post war business cycle the empirical fit of a simple stochastic growth model is significantly improved when it is amended to include imperfectly predictable fluctuations in payroll taxes consumption taxes and government consumption indeed using the simulated method of moments smm we find that for large sets of conventional moments models with stochastic fiscal policy cannot be statistically rejected whereas a model without it is always rejected

real business cycles and the animal spirits hypothesis abstract we calibrate a quantitative equilibrium macroeconomic model with an aggregate technology that is subject to increasing returns and show that this model may display fluctuations at business cycle frequencies even when there are no shocks to the fundamentals of the economy these fluctuations are due to the self fulfilling beliefs of investors which we call animal spirits we compare the impulse response functions predicted by our model and by two other more standard models with a four variable vector autoregression on u s data our animal spirits economy is the most successful of the three at matching broad features of the dynamic responses in the data journal of economic literature classification numbers e00 e3 e32

the macroeconomic effects of war finance in the united states world war ii and the korean war during world war ii government expenditures were financed primarily by issuing debt during the korean war expenditures were financed almost exclusively by higher taxes reflecting president truman s preference for balanced budgets this paper evaluates quantitatively the economic effects of the different policies used to finance these two wars counterfactual experiments are used to explore the implications of financing world war ii like the korean war and financing the korean war like world war ii the author finds that using a korean war policy during world war ii would have resulted in much lower output and welfare relative to the actual policy copyright 1997 by american economic association

fiscal spending shocks endogenous government spending and real business cycles abstract we analyze a real business cycle model in which the government optimally chooses public investment and nonmilitary current expenditures to maximize the welfare of the representative private agent we characterize the optimal response of endogenous spending to shocks to technology and to military expenditures comovements between the components of government spending and other macroeconomic aggregates predicted by the model are compared with the corresponding comovements in the u s data the model captures the qualitative features of the relative volatilities of the components of government spending quite well but predicts too high correlations between the components of government spending and output

the impact of government structure on local public expenditures though the relationship between local government structure and expenditure has received considerable attention there is little consensus as to how the features of representative government affect local expenditure an exception is city council size which has consistently been found to be positively related to spending previous results rely on cross sectional estimation which may be subject to omitted variable bias this paper analyzes three components of municipal governments the form of government the size of the city council and the election method of city councilors once fixed effects estimation is employed the positive relationship between city council size and expenditure disappears

fiscal policy and lending relationships this paper studies how fiscal policy affects loan market conditions in the us first it conducts a structural vector autoregression analysis showing that the bank spread responds negatively to an expansionary government spending shock while lending increases second it illustrates that these results are mimicked by a dynamic stochastic general equilibrium model where the bank spread is endogenized via the inclusion of a banking sector exploiting lending relationships third it shows that lending relationships represent a friction that generates a financial accelerator effect in the transmission of the fiscal shock
