long term growth and short term economic instability when learning by doing is at the origin of growth the long run growth rate should be negatively related to the amplitude of the business cycle if human capital accumulation is increasing and concave in the cyclical component of production empirical evidence strongly supports this nding for industrialized countries and european regions using the standard control variables we nd that countries and regions that have a higher standard deviation of growth and of unemployment have lower growth rates the result does not come from an e ect of instability on investment the negative relation however does not hold for non industrialized countries for which learning by doing may not to be the main engine of growth 2000 elsevier science b v all rights reserved jel classixcation o40 e32

the political economy of public income volatility with an application to the resource curse abstract in recent years many countries have witnessed a great deal of volatility in public budgets be it due to volatility in the access to foreign loans in greece or to unstable oil prices in venezuela we study the political consequences of such public income volatility as is standard in our model political incentives create inefficient policies to increase re election probabilities but we show that making public income uncertain creates specific new effects future volatility reduces the benefit of being in power making policy more efficient yet at the same time it also reduces the re election probability of an incumbent and since some of the policy inefficiencies are concentrated in the future this makes inefficient policy such as patronage public employment less costly our model highlights a new political economy connection between the volatility of the public budget and economic growth in the case where volatility comes from natural resource prices a characteristic of many developing countries we show that volatility in itself may be a source of inefficient resource extraction jointly interacting with increased patronage employment

individually rational budget balanced mechanisms and allocation of surplus abstract we investigate the issue of implementation via individually rational ex post budget balanced bayesian mechanisms we show that all decision rules generating a nonnegative expected social surplus are implementable via such mechanisms if and only if the probability distribution of the agents type profiles satisfies two conditions the well known condition of cremer and mclean 1988 full extraction of the surplus in bayesian and dominant strategy auctions econometrica 56 1247 1257 and the identifiability condition introduced in this paper we also show that these conditions are necessary for ex post efficiency to be attainable with budget balance and individual rationality and that the expected social surplus in these mechanisms can be distributed in any desirable way lastly we demonstrate that like cremer mclean condition the identifiability condition is generic if there are at least three agents

policy variability and economic growth this paper explores the effect of policy variability or frequency of regime switching on economic growth and welfare we study a one sector growth model where investment can be subsidized at either a positive rate or not subsidized at all we find that the lack of persistence in policies per se need not be welfare reducing and that it is likely to decrease growth higher variability implies more frequent changes in consumption and investment but by creating a stronger intertemporal link across regimes variability reduces the fluctuation in investment rates thus decreasing the magnitude of changes in consumption and increasing welfare

inequality and the instability of polity and policy we create alternative measures of political instability which capture only movements from dictatorship to democracy and vice versa and unlike older well known measures does not capture government changes that preserve the democratic or dictatorial structure of the country we show that inequality is positively correlated with our measures of political instability as well as with a well known measure used by alesina and perotti but the impact of inequality on the latter is only through components of political instability captured by our measures we show that our measures have significant policy implications political instability increases both fiscal and trade polity volatility

output volatility and economic growth abstract this paper proposes a new instrument to identify the causal effect of output volatility on economic growth which is based on exogenous volatility spillovers from abroad cross section evidence from 128 countries points to a negative effect of volatility on growth

balanced bayesian mechanisms in the transferable utility case a number of authors have identified conditions on beliefs that guarantee the existence of bayesian incentive compatible mechanisms with balanced transfers we present a new easy to interpret condition and we show that it is strictly more general than all the other conditions found in the literature we also study conditions guaranteeing the bayesian implementability of all social decision rules with balanced budget mechanisms

state responses to fiscal crises the effects of budgetary institutions and politics this paper explores the dynamics of state taxes and spending during the late 1980s when regional economic downturns and increased expenditure demands led to substantial state budget deficits more restrictive state fiscal institutions such as no deficit carryover rules and tax and expenditure limitations are correlated with more rapid fiscal adjustment to unexpected deficits political factors are also important when a single party controls the state house and the governorship deficit adjustment is much faster than when party control is divided in gubernatorial election years tax increases and spending cuts are both significantly smaller than at other times

government spending and budget deficits in the industrial economies fiscal policy nouriel roubini and jeffrey sachs this paper examines the evolution of the size of government and of budget deficits in oecd economies we highlight the rapid increase in government spending in the 1970s the sharp rise in budget deficits and public debt after 1973 and the reversal in these trends in the 1980s the increase in the size of government was associated in part with the slowdown in growth after 1973 but also reflected gradual adjustment of the ratio of spending to output towards a long run target which depends on political and institutional characteristics of the economy the political orientation of the government the degree of wage indexation and the degree of stability of the political system such factors also explain the size of budget deficits when faced with an adverse shock subsequent deficit reduction requires a measure of political consensus we note that such consensus is hard to achieve in multi party coalitions in consequence countries with such a political structure tended in consequence countries with such a political structure tended toin consequence countries with such a political structure tended to experience much more rapid increases in their debt gnp ratios

cyclical expenditure policy output volatility and economic growth this article provides an empirical assessment of the relation between the cyclicality of fiscal expenditure policy output volatility and economic growth using a cross section of 88 countries over the period 1960 to 2004 identification of the effects of endogenous cyclical expenditure policy is achieved by exploiting the exogeneity of countries political and institutional characteristics which we find to be relevant determinants of the cyclicality of expenditures there are three main results first both pro and countercyclical expenditure policy amplify output volatility much in a way like pure fiscal shocks second output volatility due to variations in cyclical and discretionary fiscal policy is negatively associated with economic growth third there is no direct effect of cyclicality on economic growth other than through output volatility

a quantitative analysis of chinese industrial structure and technological change production functions for aggregate industry sectoral industries and small scale industry in this study we estimate the chinese aggregate sectoral and small scale industrial production functions based of three models the ces 1 ces 2 and cobb douglas production functions testing the estimated results we find that the cobb douglas production function is the appropriate functional form for underlying chinese industrial struture the study indicates some serious structural and technological problems such as decreasing returns to scale unitary substitution between labour and capital slow technical progress and low economic efficienty the findings suggest that an intensive industrial development policy should be pursued in china

the case for restricting fiscal policy discretion this paper studies the effects of discretionary fiscal policy on output volatility and economic growth using data for 91 countries we isolate three empirical regularities 1 governments that use fiscal policy aggressively induce significant macroeconomic instability 2 the volatility of output caused by discretionary fiscal policy lowers economic growth by more than 0 8 percentage points for every percentage point increase in volatility 3 prudent use of fiscal policy is explained to a large extent by the presence of political constraints and other political and institutional variables the evidence in the paper supports arguments for constraining discretion by imposing institutional restrictions on governments as a way to reduce output volatility and increase the rate of economic growth

on sustained growth under uncertainty we analyze a stochastic one sector model of economic growth and investigate the conditions under which long run growth occurs almost surely in contrast to the deterministic version of the model the utility function plays a crucial role in determining the long run behavior of output the central purpose of theories of economic growth is to understand the factors behind long run growth of economies and to explain differences in growth performances of economies in terms of fundamental endowments and choices a wide class of endogenous growth models has been specified in the last decade and they have explored a large array of possible explanatory variables for the differences in observed growth rates between countries with some notable exceptions most of these models are deterministic and therefore ignore the fundamental uncertainties which affect productivity and cause diversity between growth of nations the exceptions which include real business cycle models that examine the consequence of productivity shocks in endogenous growth frameworks use specific utility and production functions drawn from the log linear family see among others king et al 1988 king and rebelo 1988 de hek 1999 jones et al 1999 a general analysis of the phenomenon of sustained growth in economies subject to technological shocks is not yet available and the kind of conditions needed to guarantee sustained stochastic growth are not well understood in this article we address this issue in the simple framework of a stochastic one sector convex growth model when the technology is globally productive in the sense that marginal productivity of investment is bounded above one output and consumption flows can grow indefinitely i e long run growth is feasible whether such growth actually occurs depends on the intertemporal preference structure 2 in the deterministic version of this model this problem was first discussed by gale and sutherland 1968 who extended the classical optimal growth analysis to the case of such a productive technology more recently jones and manuelli 1990 have rigorously characterized the possibility of sustained long run growth in a variant of the one sector deterministic growth model see also rebelo 1991 3 the main result is that long run growth

divided government fiscal institutions and budget deficits evidence from the states does partisan control of american state government have systematic effects on state spending and taxing levels does divided control affect the government s ability to make hard decisions do institutional rules like legal deficit carryover restrictions matter using a formal model of fiscal policy to guide empirical analysis of data covering the american states from 1968 to 1987 we conclude that 1 aggregate state budget totals are driven by different factors under democrats and republicans the net result being that democrats target spending and taxes to higher shares of state level personal income 2 divided government is less able to react to revenue shocks that lead to budget deficits particularly where different parties control each chamber of the legislature and 3 unified party governments with restricted ability to carry deficits into the next fiscal year outside the south have sharper reactions to negative revenue shocks than those without restrictions

major oecd country industrial sector interfuel substitution estimates 1960 1979 abstract a range of static and dynamic translog based expenditure shares models are estimated for non energy producing industrial sectors of the major seven countries of the oecd area sectoral energy volume and fuel efficiency bias variables are shown to be significant over and above individual prices in explaining individual fuel expenditure shares statistically significant own price and cross price elasticities of demand are presented for individual countries with some magnitudes varying considerably across alternative model specifications

constitutional rules and fiscal policy outcomes we investigate the effect of electoral rules and forms of government on fiscal policy outcomes in a large sample of democracies we rely on different estimation methods to address prospective problems of statistical inference due to non random selection of these constitutional rules the findings are consistent with our theoretical priors presidential regimes induce smaller governments than parliamentary democracies while majoritarian elections lead to smaller governments and smaller welfare programs than proportional elections

fiscal policy and monetary integration in europe fiscal policy economists policy makers and the media often argue that the maastricht treaty and the stability and growth pact make it difficult for governments of emu countries to stabilize their economies with appropriate fiscal policy and to provide adequate public investment our empirical analysis offers little support to this view discretionary budget deficits have actually become more counter cyclical in emu countries after the maastricht treaty as well as in the other eu and non eu industrialized countries we study and while public investment has declined recently in emu countries a similar tendency is apparent in other countries and started well before the maastricht treaty was signed jordi gali and roberto perotti

immigrant earnings differentials and birth year effects for men in canada post war 1972 this paper investigates immigrant earnings differentials for males in canada and how these earnings have changed over time leading up to 1972 with workers year of birth the paper uses the 1973 job mobility survey which contains a direct measure of work experience reported independent of age thus using age as a birth year index it is found that cross sectional earnings differentials of immigrant men have widened since the later 1960s relative to those of native born workers summary in fre excerpt

role of linking mechanisms in multitask agency with hidden information we investigate the adverse selection problem where a principal delegates multiple tasks to an agent we characterize the virtually implementable social choice functions by using the linking mechanism proposed by jackson and sonnenschein 2007 that restricts the message spaces the principal does not require any incentive wage schemes and can therefore avoid any information rent and welfare loss we show the resemblance between the functioning of this message space restriction and that of incentive wage schemes we also extend the results of the single agent model to the multi agent model

long dark shadows or innovative spirits the effects of smoothing business cycles on economic growth a survey of the literature abstract it is argued that fiscal policy can play a part in preventing a possible downward spiral or be instrumental in achieving a higher long term path of growth never before has this argument been advanced as frequently as in the current economic crisis however the economic literature an overview of which is given here does not provide an unambiguous answer either theoretically or empirically to the question of the relationship between the smoothing of cyclical fluctuations and long term growth in this context two main contrasting explanatory paradigms can be identified schumpeter s concept of creative destruction and the learning by doing hypothesis even if it were possible to identify the relationship more clearly on this basis it is important not to lose sight of the problems associated with the real time assessment of the current economic situation time lags and political economic incentives even in difficult times

elasticity of substitution technical progress and returns to scale in branches of soviet industry a new ces production function approach this study introduces and tests a new ces production function approach using data from five major branches of the soviet industrial sector the estimated equations obtained suggest that the cobb douglas production function is the appropriate production function for all branches under consideration except food processing

why is fiscal policy often procyclical many countries especially developing ones follow procyclical fiscal policies namely spending goes up taxes go down in booms and spending goes down taxes go up in recessions we provide an explanation for this suboptimal fiscal policy based upon political distortions and incentives for less than benevolent government to appropriate rents voters have incentives similar to the starving the leviathan classic argument and demand more public goods or fewer taxes to prevent governments from appropriating rents when the economy is doing well we test this argument against more traditional explanations based purely on borrowing constraints with a reasonable amount of success

correlated types and bayesian incentive compatible mechanisms with budget balance abstract this note presents a condition which guarantees the existence of a bayesian incentive compatible mechanism with budget balance when agents have quasi linear utility functions this condition requires correlation among agents private signals types and is 1 simple and easy to verify 2 good for any decision rule whether efficient or not 3 valid even if agents types are mutually payoff relevant and 4 true for almost every probability distribution of agents types journal of economic literatureclassification numbers c72 d82

the economics of split ticket voting in representative democracies in u s elections voters often vote for candidates from different parties for president and congress voters also express dissatisfaction with the performance of congress as a whole and satisfaction with their own representative the authors develop a model of split ticket voting in which government spending is financed by uniform taxes the benefits from this spending are concentrated while the model generates split ticket voting overall spending is too high only if the president s powers are limited overall spending is too high in a parliamentary system the authors model can be used as the basis of an argument for term limits copyright 1997 by american economic association

why do more polarized countries run more procyclical fiscal policy abstract we study the cyclical behavior of fiscal policy to explain why some countries exhibit procyclical fiscal policy stances being expansionary in good times and contractionary in bad times we develop a model that links the polarization of preferences over fiscal spending to the procyclicality bias we then present evidence that social polarization as measured by income inequality and educational inequality is consistently and positively associated with fiscal procyclicality even after controlling for other determinants from existing theories we also find a strong negative impact of fiscal procyclicality on economic growth

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

the cyclical behaviour of fiscal policy evidence from the oecd this paper addresses the topic of cyclicality in scal policy in particular we show that the level of cyclicality varies across spending categories and across oecd countries in line with leading theories of scal cyclicality we show that countries with volatile output and dispersed political power are the most likely to run procyclical scal policies wage government consumption is highlighted as the most important channel by which these variables affect scal cyclicality

macroeconomic volatility and welfare in developing countries an introduction macroeconomic volatility both a source and a reflection of underdevelopment is a fundamental concern for developing countries their high aggregate instability results from a combination of large external shocks volatile macroeconomic policies microeconomic rigidities and weak institutions volatility entails a direct welfare cost for risk averse individuals as well as an indirect one through its adverse effect on income growth and development this article provides a brief overview of the recent literature on macroeconomic volatility in developing countries highlighting its causes consequences and possible remedies it then introduces the contributions of a recent conference on the subject sponsored by the world bank and pompeu fabra university barcelona

soviet postwar industrial growth and capital labour substitution an empirical note abstract this note tests an aggregate transcendental production function for soviet industry the estimated equation shows the elasticity of substitution in aggregate soviet industry in less than unity and it is decreasing quite rapidly

institutional causes macroeconomic symptoms volatility crises and growth countries that have pursued distortionary macroeconomic policies including high inflation large budget deficits and misaligned exchange rates appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period does this reflect the causal effect of these macroeconomic policies on economic outcomes one reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak institutions including political institutions that do not constrain politicians and political elites ineffective enforcement of property rights for investors widespread corruption and a high degree of political instability this paper documents that countries that inherited more extractive institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period more specifically societies where european colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises based on our previous work we interpret this relationship as due to the causal effect of institutions on economic outcomes europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality once we control for the effect of institutions macroeconomic policies appear to have only a minor impact on volatility and crises this suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic

functional form and new production functions some comments and a new ves function this paper discusses new production function forms which are devised to generalise two restrictive features of the maintained hypotheses concerning homogeneity and the substitution effect of the original acms function

incentive compatible mechanisms with full transferability abstract we consider the bayesian collective choice problem with side payment we introduce the regularity condition which describes the case that agents have mutually correlated private information under the regularity condition we construct a transfer rule with budget balancing which together with the efficient public decision rule is incentive compatible truth telling may be a unique iteratively undominated strategy profile in our direct mechanism

volatility and development why is gdp growth so much more volatile in poor countries than in rich ones we identify four possible reasons i poor countries specialize in more volatile sectors ii poor countries specialize in fewer sectors iii poor countries experience more frequent and more severe aggregate shocks e g from macroeconomic policy and iv poor countries macroeconomic fluctuations are more highly correlated with the shocks of the sectors they specialize in we show how to decompose volatility into these four sources quantify their contribution to aggregate volatility and study how they relate to the stage of development we document the following regularities first as countries develop their productive structure moves from more volatile to less volatile sectors second the level of specialization declines with development at early stages and slowly increases at later stages of development third the volatility of country specific macroeconomic shocks falls with development fourth the covariance between sector specific and country specific shocks does not vary systematically with the level of development we argue that many theories linking volatility and development are not consistent with these findings and suggest new directions for future theoretical work

policy volatility institutions and economic growth abstract in this paper we present evidence that policy volatility exerts a strong and direct negative impact on growth using data for 93 countries we construct measures of policy volatility based on the standard deviation of the residuals from country specific regressions of government consumption on output undisciplined governments that implement frequent and large changes in government spending unrelated to the state of the business cycle generate lower economic growth we employ both instrumental variables and panel estimation to address concerns of omitted variables and endogeneity a 1 standard deviation increase in policy volatility reduces long term economic growth by about 0 74 in the panel regressions and by more than 1 percentage point in the cross section

the cost of business cycles under endogenous growth robert e lucas jr argued that the welfare gains from reducing aggregate consumption volatility are negligible subsequent work that revisited his calculation continued to find small welfare benefits further reinforcing the perception that business cycles do not matter this paper argues instead that fluctuations can affect welfare by affecting the growth rate of consumption i show that fluctuations can reduce growth starting from a given initial consumption which can imply substantial welfare effects as lucas himself observed empirical evidence suggests the welfare effects are likely to be substantial about two orders of magnitude greater than lucas original estimates

the cleansing effect of recessions the authors investigate industry response to cyclical variations in demand production units that embody the newest process and product innovations are continuously being created and outdated units are being destroyed although outdated units are the most likely to turn unprofitable and be scrapped in a recession they can be insulated from the fall in demand by a reduction in creation the structure of adjustment costs plays a determinant role in the responsiveness of those two margins the calibrated model matches the relative volatilities of the observed manufacturing job creation and destruction series and their asymmetries over the cycle copyright 1994 by american economic association

on the choice of production functions the case of us manufacturing industries a new ces bairam 1989 1991 production function that has the cobb douglas and leontief functions as special cases is considered and estimated for the nondurable goods and durable goods sectors in us manufacturing the translog and ces functions cannot be estimated properly due to multicollinearity whereas the cobb douglas and new ces functions yield coefficients that have the correct sign and are significant at the 1 or 5 level both sectors exhibited increasing returns to scale though the nondurable goods sector is more efficient than the other sector although the cobb douglas function cannot be rejected the new ces functions has the maximized value of the log likelihood function and the advantage that the variable output elasticity with respect to inputs can be tested

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association
