interest groups and the rise and decline of growth interest groups are known to exert a sclerotic impact on mean growth a la olson 1982 it is unknown however what impact if any groups exert on the volatility of growth an important hindrance to development in this article we first consider what impact we should expect olson groups to have on the volatility of growth we then estimate the relation between groups and growth volatility in a cross country panel using system generalized method of moments the findings indicate that groups are associated with growth stability in addition the findings suggest that interest groups may be a source of the stability observed in democracies

do r d tax credits work evidence from a panel of countries 1979 1997 this paper examines the impact of fiscal incentives on the level of r d investment an econometric model of r d investment is estimated using a new panel of data on tax changes and r d spending in nine oecd countries over a 19 year period 1979 1997 we find evidence that tax incentives are effective in increasing r d intensity this is true even after allowing for permanent country specific characteristics world macro shocks and other policy influences we estimate that a 10 fall in the cost of r d stimulates just over a 1 rise in the level of r d in the short run and just under a 10 rise in r d in the long run

interpreting the great moderation changes in the volatility of economic activity at the macro and micro levels most advanced economies have experienced a striking decline in the volatility of aggregate economic activity since the early 1980s volatility reductions are evident for output and employment at the aggregate level and across most industrial sectors and expenditure categories inflation and inflation volatility have also declined dramatically previous studies offer several potential explanations for this great moderation we review evidence on the great moderation in conjunction with evidence about volatility trends at the micro level we combine the two types of evidence to develop a tentative story for important components of the aggregate volatility decline and its consequences the key ingredients are declines in firm level volatility and aggregate volatility most dramatically in the durable goods sector surprisingly this has occurred without a decline in household consumption volatility and individual earnings uncertainty our explanation for the aggregate volatility decline stresses improved supply chain management particularly in the durable goods sector and less important a shift in production and employment from goods to services we provide evidence that better inventory control made a substantial contribution to declines in firm level and aggregate volatility consistent with this view if we look past the turbulent 1970s and early 1980s much of the moderation reflects a decline in high frequency short term fluctuations while these developments represent efficiency gains they do not imply nor is there evidence for a reduction in economic uncertainty faced by individuals and households

a theory of sticky rents search and bargaining with incomplete information abstract this paper offers the first theoretical explanation of housing rent stickiness and differential stickiness by housing structure type key features of rental markets worldwide previous theoretical work on the subject is sparse and explains why some landlords charge below market rents not stickiness apart from its interest for understanding housing markets and overall inflation rent stickiness is intriguing because it shows that stickiness can emerge in markets where the typical menu cost logic does not apply and where market participants typically engage in repeated bargaining over contracts our model involves search and bargaining with incomplete information in a two period game and generates stickiness in a novel manner the key decision is the landlord s choice of whether to renegotiate or not crucially landlords do not know tenant perceptions of unit quality the key force generating stickiness is that offering the identical contract preempts tenant search thus limiting tenants outside options and resolves uncertainty early risk aversion reinforces this mechanism and yields differential stickiness by landlord type renegotiation risk for large landlords disappears because the different outcomes rent increase rent decrease and vacancy average out landlords who manage only one unit loathe vacancy and are highly motivated to avoid renegotiation

real sources of european currency policy sectoral interests and european monetary integration in the thirty years before economic and monetary union was achieved european currency policies varied widely among countries and over time in this article i argue that the sectoral impact of regional exchange rate arrangements in particular their expected real effects on european trade and investment exerted a powerful influence on the course of european monetary integration the principal benefit of fixing european exchange rates was facilitation of cross border trade and investment within the european union eu the principal cost of fixed rates was the loss of national governments ability to use currency policy to improve their producers competitive position empirical results indeed indicate that a stronger and more stable currency was associated with greater importance of manufactured exports to the eu s hard currency core while depreciations were associated with an increase in the net import competition faced by the country s producers this suggests a powerful impact of real factors related to trade and investment and of private interests concerned about these factors in determining national currency policies

veto players and the choice of monetary institutions i argue that two types of veto players matter in the choice of monetary institutions party veto players and subnational governments which are strong in federal systems but weak in unitary systems a crucial issue is whether voters can readily identify the manipulation of the economy with party players a second issue concerns the national party veto player s ability to control either fiscal or monetary policy in one party unitary governments identification and control are clear parties where such governments are common prefer flexible exchange rates and dependent central banks in multiparty coalition governments in unitary systems identification is traditionally difficult and the ability to target benefits to specific constituencies under fiscal policy makes fiscal policy autonomy more attractive for coalition governments such governments prefer central banks that are politically independent but that finance government debt under federalism parties that constitute the central government have less control over fiscal policy and they prefer flexible exchange rates subnational governments do not support a dependent central bank that gives more power to the central government

the rationale of the mean standard deviation analysis skewness preference and the demand for money publisher summary this chapter discusses the rationale of the mean standard deviation analysis skewness preference and the demand for money in january 1969 issue of the review of economic studies karl borch and martin feldstein separately criticized the widely used mean variance analysis of portfolio selection borch contended that any system of upward sloping mean standard deviation e s indifference curves can be shown to be inconsistent with the basic axiom of choice under uncertainty he pointed out that one can always pick any two points on an upward sloping indifference curve to represent two bernoulli distributions with probability 1 p of gaining the same amount x in both the cases and probability p of gaining y1 in the case of one distribution and y2 in the case of the second distribution with y2 y1 if the second distribution represents the point to the northeast of the other point then by the dominance axiom the second distribution must be preferred to the first which contradicts the basic meaning of indifference curves feldstein by using a log utility function and a lognormal distribution for investment outcome showed that e s indifference curves for a risk averter need not be convex downwards though upward sloping they would change from convex to concave once the standard deviation of the outcome exceeds the mean multiplied by on the face of it this seems to suggest that risk aversion might decrease as risk is increased beyond a certain extent

volatility of short term capital flows and private investment in emerging markets abstract using micro level panel data the paper analyses the impacts of short term capital flow volatility on new fixed investment spending of publicly traded real sector firms in three major emerging markets argentina mexico and turkey the empirical results including sensitivity tests suggest that increasing volatility of capital inflows has an economically and statistically significant negative effect on new investment spending of private firms accordingly a 10 per cent increase in capital flow volatility reduces fixed investment spending in the range of 1 1 7 2 3 15 and 1 per cent in argentina mexico and turkey respectively

choice of varieties by sri lanka rice farmers comparing alternative decision models sri lanka rice farmers are faced with a choice between traditional and high yielding rice varieties three risky choice models are compared to explain producer behavior forty farmers with typically small rice areas were studied choice criteria compared were multiple two attribute utility maximization single profit attribute utility maximization and expected profit maximization expected utility maximization performed better than expected profit maximization single attribute utility maximization outperformed the more complex multiattribute utility model the importance of careful elicitation of subjective probability distributions is emphasized rice farmers appear to allocate their land between available technologies in an economically rational way

simplified risk analysis in agricultural extension abstract attention is given to the major methods of assessing risk in order to make choices the literature frequently reports studies on mean variance e v analysis and stochastic dominance rules both of these methods are compared in an agricultural application with the approach outlined by hanoch and levy the empirical results suggests that hanoch and levy s criterion appear to reduce the size of the risk efficient set and that the sets of recommendations from the methods under comparison were consistent the two recommendations generated by hanoch and levy s rule were found to be reasonable for this particular decision process

information rigidity and the expectations formation process a simple framework and new facts we propose a new approach to test the full information rational expectations hypothesis which can identify whether rejections of the null arise from irrationality or limited information this approach quantifies the economic significance of departures from the null by quantifying the underlying degree of information rigidity applying this approach to u s and international data of professional forecasters and other agents yields pervasive evidence consistent with models of imperfect information furthermore the proposed approach sheds new light on policies such as inflation targeting and those leading to the great moderation affecting expectations finally we document evidence of state dependence in the expectations formation process

a theory of growth and volatility at the aggregate and firm level abstract we present an endogenous growth model that explains the evolution of the first and second moments of productivity growth at the aggregate and firm level during the post war period growth is driven by the development of both i idiosyncratic r d innovations and ii general innovations that can be freely adopted by many firms firm level volatility is affected primarily by the schumpeterian dynamics associated with the development of r d innovations the variance of aggregate productivity growth is driven by the arrival rate of general innovations ceteris paribus the share of resources spent on development of general innovations increases with the stability of the market share of the industry leader as market shares become less persistent the model predicts an endogenous shift in the allocation of resources from the development of general innovations to the development of r d innovations this results in an increase in r d an increase in firm level volatility and a decline in aggregate volatility the effect on productivity growth is ambiguous on the empirical side this paper presents new cross country evidence that r d subsidies are not significantly associated with higher growth but are associated with lower aggregate volatility it also documents an upward trend in the instability of market shares a positive association between firm volatility and r d spending and a negative association across sectors between r d and how correlated the sector is with the rest of the economy

deep financial integration and volatility we investigate the relationship between foreign direct ownership of firms and firm and region level output volatility using a novel panel data set for european countries we document a positive highly robust relationship between firm level foreign ownership and volatility of value added this relationship holds cross sectionally and in panels with firm fixed effects where the relationship captures within firm variation over time considering domestic firms with assets in foreign countries we document that it is international diversification rather than the nationality of the owner that explains this positive correlation our results can also be found at the aggregate level where we show that region level volatility is correlated positively with foreign investment in the region we show that this positive relation between aggregate volatility and foreign investment can be explained by the granularity of the firm size distribution and the fact that foreign ownership is concentrated among the largest firms

democratic institutions and exchange rate commitments since the collapse of the bretton woods system countries have been able to choose from a variety of exchange rate arrangements we argue that politicians incentives condition the choice of an exchange rate arrangement these incentives reflect the configuration of domestic political institutions particularly electoral and legislative institutions in systems where the cost of electoral defeat is high and electoral timing is exogenous politicians will be less willing to forgo their discretion over monetary policy with a fixed exchange rate in systems where the costs of electoral defeat are low and electoral timing is endogenous politicians are more likely to adopt a fixed exchange rate regime consequently differences in domestic political systems can help account for variations in the choice of exchange rate arrangements we test this argument using constrained multinomial logit and binomial logit on a sample of twenty democracies over the period 1974 95 domestic political institutions have a significant effect on exchange rate regime choice even after controlling for systemic macroeconomic and other political variables

evidence that the zero earnings discontinuity has disappeared abstract discontinuities in earnings distributions at zero have been widely cited as evidence of earnings management but not without controversy recent research suggests discontinuities may be mere artifacts of certain research design choices we find that the well known zero earnings discontinuity disappears soon after passage of the sarbanes oxley act sox and has not returned we also find that neither the discontinuity nor its disappearance require the effects of widely cited alternative non earnings management explanations for the zero earnings discontinuity

financial liberalization private investment and portfolio choice financialization of real sectors in emerging markets abstract using firm level panel data we analyze the impacts of rates of return gap between financial and fixed investments under uncertainty on real investment performance in three emerging markets argentina mexico and turkey employing a portfolio choice model to explain the low fixed investment rates in developing countries during the 1990s we suggest that rather than investing in irreversible long term fixed investments firms may choose to invest in reversible short term financial investments depending on respective rates of returns and the overall uncertainty in the economy the empirical results show that increasing rates of return gap and uncertainty have an economically and statistically significant fixed investment reducing effect while the opposite is true with respect to financial investments

societal preferences partisan agents and monetary policy outcomes if different producer groups have divergent interests concerning macroeconomic policies how do societal preferences translate into state policy outcomes i develop and test a party as agent framework for understanding the importance of societal preferences with regard to monetary policy under capital mobility following the principal agent model political parties function as agents for different societal principals rightist parties tend to represent internationally oriented business groups with preferences for monetary convergence while leftist parties do the same for domestically oriented groups preferring monetary autonomy under capital mobility i present statistical evidence showing that oecd leftist governments have been associated with more monetary autonomy and currency variability than their rightist counterparts even after controlling for basic economic indicators such as inflation the statistical evidence also shows that societal group size tends not to explain either autonomous monetary policy choices or exchangerate stability thus even large and wealthy societal groups may be unable to obtain their preferred policy outcome when their respective partisan agents do not hold government power

technology shocks and monetary policy assessing the fed s performance abstract the purpose of the present paper is twofold first we characterize the fed s systematic response to technology shocks and its implications for u s output hours and inflation second we evaluate the extent to which those responses can be accounted for by a simple monetary policy rule including the optimal one in the context of a standard business cycle model with sticky prices our main results can be described as follows first we detect significant differences across periods in the response of the economy as well as the fed s to a technology shock second the fed s response to a technology shock in the volcker greenspan period is consistent with an optimal monetary policy rule third in the pre volcker period the fed s policy tended to overstabilize output at the cost of generating excessive inflation volatility our evidence reinforces recent results in the literature suggesting an improvement in the fed s performance

turbulent firms turbulent wages abstract has greater turbulence among firms fueled rising wage instability in the u s we find strong support for the hypothesis that rising turbulence in the sales of large publicly traded u s firms over the past three decades has raised their workers high frequency wage volatility through controls and instrumental variable probes we rule out straightforward compositional churning as an explanation for the link between firm sales and wage volatility we also observe that the relationship between sales and wage volatility at the firm level is stronger since 1980 is present only in large companies and is stronger in services than in manufacturing companies

gibrat s law and quantile regressions an application to firm growth abstract the nexus between firm growth size and age in u s manufacturing is examined through the lens of quantile regression models this methodology allows us to overcome serious shortcomings entailed by linear regression models employed by much of the existing literature unveiling a number of important properties size pushes both low and high performing firms towards the median rate of growth while age is never advantageous and more so as firms are relatively small and grow faster these findings support theoretical generalizations of gibrat s law that allow size to affect the variance of the growth process but not its mean cordoba 2008

the political economy of monetary institutions in recent decades countries have experimented with a variety of monetary institutions including alternative exchange rate arrangements and different levels of central bank independence political economists have analyzed the choice of these institutions emphasizing their role in resolving both the time inconsistency problem and dilemmas created by an open economy this first generation work however suffers from a central limitation it studies exchange rate regimes and central bank institutions in isolation from one another without investigating how one monetary institution affects the costs and benefits of the other by contrast the contributors to this volume analyze the choice of exchange rate regime and central bank independence together and in so doing present a second generation of research on the determinants of monetary institutions the articles incorporate both economic and political factors in explaining the choice of monetary institutions investigating how political institutions democratic processes political party competition and interest group pressures affect the balance between economic and distributional policy objectives

the time varying volatility of macroeconomic fluctuations we investigate the sources of the important shifts in the volatility of us mac roeconomic variables in the postwar period to this end we propose the esti mation of dsge models allowing for time variation in the volatility of the structural innovations we apply our estimation strategy to a large scale model of the business cycle and find that shocks specific to the equilibrium condition of investment account for most of the sharp decline in volatility of the last two decades jel c51 e32

diverging trends in aggregate and firm volatility this note documents the diverging trends in volatility of the growth rate of sales at the aggregate and firm levels we establish that the upward trend in firm volatility is not simply driven by a compositional bias in the sample studied we argue that this new fact brings into question the proposed explanations for the decline in aggregate volatility and that given the symmetry of the diverging trends at the micro and macro levels a common explanation is likely we conclude by describing one such theory

the advantage of tying one s hands ems discipline and central bank credibility abstract it is often argued that the ems is an effective disciplinary device for inflation prone countries in europe since it forces the respective policy makers to pursue more restrictive monetary policies than they would otherwise it is not clear however why these countries should submit themselves to such discipline this paper argues that to answer this question appropriately one must consider that ems membership brings potentially large credibility gains policy makers in inflation prone countries the reason is that not only it attaches an extra penalty to inflation in terms of real appreciation but makes the public aware that the policy maker is faced with such penalty and thus helps to overcome the inefficiency stemming from the public s mistrust of the authorities

checks and balances private information and the credibility of monetary commitments the authors develop and test several new hypotheses about the anti inflationary effect of central bank independence and exchange rate pegs in the context of different institutions and different degrees of citizen information about government policies theory provides strong reason to believe that while central bank independence will prove more effective as a commitment mechanism in countries where multiple players in government have veto power checks and balances the number of veto players will have no effect on the credibility of exchange rate pegs conversely the authors argue that central bank independence does not solve the problems of commitment that arise when citizens are imperfectly informed about the contribution of government policy to inflation exchange rate pegs however mitigate these problems the authors present extensive evidence from cross country tests using newly developed data that provide strong support for their propositions

capital market imperfections and financialization of real sectors in emerging markets private investment and cash flow relationship revisited summary the paper analyzes the impacts of cash flow from multiple investments in real and financial sectors on the new fixed investment spending of real sector firms the empirical results based on the euler equation approach and semi annual firm level data from two major emerging markets mexico and turkey suggest that profits and rates of returns from fixed and financial assets have differential effects on fixed investment spending of real sector firms accordingly increasing availability and accessibility of alternative investment opportunities in financial markets can become instrumental in channeling real sector savings to short term financial investments instead of long term fixed capital formation and thus lead to deindustrialization

escaping the ties that bind exchange rate choice under central bank independence central bank independence has been seen as an effective way to achieve low inflation however by increasing the likelihood that the government will adopt a fixed exchange rate rather than maintain domestic control over monetary policy an independent central bank may be a victim of its own success because monetary policy set by an independent central bank may result in what the government considers to be adverse distributive consequences governments may look for ways to mitigate the central bank s control over monetary policy turning to a fixed exchange rate as one possible solution the author examines the implications of this argument through an analysis of the british german and french governments preferences on joining the european monetary system in 1978

exchange rate regimes and independent central banks a correlated choice of imperfectly credible institutions theory and empirical evidence show that low inflation is a precondition for economic growth independent central banks and fixed exchange rates are institutional mechanisms that help keep inflation low by lending monetary policy credibility to governments however the two institutions are commonly analyzed as substitutes that tie the hands of inflation prone governments thus the literature has difficulties describing why governments would adopt both institutions and the interaction between them this paper presents a model that allows policymakers the simultaneous choice of monetary institutions and shows that imperfectly credible institutions will overlap when exchange rates are fixed but adjustable and central bank independence is not fully ascertainable governments choose both institutions more generally the paper generates hypotheses about the conditions that make fixed exchange rates and independent central banks complements or substitutes thus contributing to an explanation of the diversity of global monetary institutions in the post bretton woods period

mobile capital domestic institutions and electorally induced monetary and fiscal policy the literature on global integration and national policy autonomy often ignores a central result from open economy macroeconomics capital mobility constrains monetary policy when the exchange rate is fixed and fiscal policy when the exchange rate is flexible similarly examinations of the electoral determinants of monetary and fiscal policy typically ignore international pressures altogether we develop a formal model to analyze the interaction between fiscal and monetary policymakers under various exchange rate regimes and the degrees of central bank independence we test the model using data from oecd countries we find evidence that preelectoral monetary expansions occur only when the exchange rate is flexible and central bank independence is low preelectoral fiscal expansions occur when the exchange rate is fixed we then explore the implications of our model for arguments that emphasize the partisan sources of macroeconomic policy and for the conduct of fiscal policy after economic and monetary union in europe

public r d policies and cost behavior of the us manufacturing industries abstract this paper estimates and evaluates the contribution of r d tax incentives and publicly financed r d investment policies in promoting the growth of output and privately funded r d investment in us manufacturing industries publicly financed r d induced cost savings but crowds out privately financed r d investment while the incremental r d tax credit and immediate deductibility provision of r d expenditures have a significant impact on privately financed r d investment the optimal mix of both instruments is an important element for sustaining a balanced growth in output and productivity in the manufacturing sector

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

growth volatility and size a firm level study abstract this paper provides a systematic cross country investigation of the relation between a firm s growth volatility and its size for the first time the analysis is carried out using comparable and representative sets of data sourced by official business registers of an important number of countries we show that there exists a robust negative relation between growth volatility and size with an average elasticity equal to 0 18 we check the robustness of this result against a number of potential sources of bias and in particular with respect to sectoral disaggregation and against the inclusion of firm age our result is consistent with the idea that independently from specific country characteristics there exists a common underlying mechanism driving the elasticity between size and growth volatility we then propose two mechanisms able to explain our result and we conclude discussing its relevance with respect to the recent literature on granularity

volatility and slow technology diffusion abstract i study the effects of uncertainty on technology adoption and thereby on volatility and growth i present an analytically tractable model in which i uncertainty about the returns to adoption delays technology diffusion and ii the mean and volatility of output growth are jointly determined in equilibrium i then test the key predictions of the model by studying the introduction of three major information and communication technologies icts computers internet and cell phones i find that countries with more volatile growth rates of real gdp per capita have higher time adoption lags and lower average growth as predicted by the model

political and monetary institutions and public financial policies in the industrial countries institutions and policies vittorio grilli donato masciandaro and guido tabellini why do countries as similar as the industrialized oecd countries go through such different experience in terms of public deficits and debts or in terms of inflation the answer cannot come from macroeconomic policy responses to different disturbances nor from the principles of optimal taxation but rather from politics this article focuses on the role that particular institutions exert in providing constraints and incentives which shape the actions of policymakers the electoral process and political traditions affect the ability of governments to deal with deficits and mounting debts what seems to matter most it is found is the effect of the durability of governments governments with short horizons act myopically and never quite tackle the hard choices such governments typically exist in countries with an electoral system favouring many small political parties central bank independence promotes low inflation with no apparent costs in terms of real economic performance irrespective of the political institutions in fact there is no link between monetary and fiscal discipline these findings carry powerful implications for countries facing high indebtedness or stubborn inflation but also for the construction of the european economic and monetary union

varying heterogeneity among u s firms facts and implications abstract u s firms stock return volatility rose fivefold from 1971 through 2000 and then reverted to near 1971 levels by 2006 this was driven mainly by a rise and fall in the firm specific rather than systematic component of volatility firm level total factor productivity growth volatility exhibited a similar pattern we hypothesize that firm heterogeneity reflected in firm specific volatility rises as a new general purpose technology gpt propagates across the economy and then ebbs once the gpt is widespread measuring gpt adoption by information technology capital intensity we find robust cross industry empirical evidence supporting the hypothesis

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

cyclical changes in firm volatility we estimate changes in the volatility of firm level sales earnings and employment growth of us firms our method differs from existing measures for firm level sales and employment volatility in that it not only captures longer run changes in volatility but also measures cyclical changes in firm volatility we detect substantial cyclical variation in firm specific volatility around trend firm specific volatility was low in the early 1990s rose in the mid and late 1990s and was high around 2000 our results are consistent with the hypothesis deduced from models with financial frictions that rising idiosyncratic volatility before 2001 contributed to the coincident rise in the external finance premium and to the 2001 recession endogenous pricing models imply that price adjustment is less frequent and disinflation more costly when firm specific volatility is low consistent with endogenous pricing models we find that the output cost of disinflation was three times larger in the early 1990s than in the early 2000s

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
