lords of the harvest third party influence and regulatory approval of genetically modified organisms little is known about the factors that influence regulatory agency decision making we posit that regulatory agencies are influenced by the firms they regulate but not exclusively via dyadic exchanges as is traditionally argued in the regulatory capture and business government literatures instead regulatory decisions are indirectly shaped via third party actors who shield agencies from legitimacy threats focusing empirically on the united states department of agriculture s usda approval of genetically modified organisms gmos we find that product assessments by powerful stakeholders and peer agencies influence product approval and that their effects vary under different threats we also discuss the implications of these findings for businessgovernment relations nonmarket strategy and organization theory

on the role of small models in macrodynamics abstract this paper focuses on the role of small models in macrodynamics it discusses the insights that i believe these models offer and the extent to which they can address some of the complex issues such as heterogeneity and interactions among agents that are receiving increasing attention in the literature i comment on what i view to be the most productive role for numerical simulations and finally offer some brief comments in defense of the state of modern macroeconomic theory in light of the criticism it has received as a result of the recent financial crisis

financial intermediary coalitions abstract in this article an environment in which the investment opportunities of agents are private information is studied and it is shown that financial intermediaries arise endogenously within that environment it is established that financial intermediaries are part of an efficient arrangement in the sense that they are needed to support the authors private information core allocations these intermediaries which are coalitions of agents exhibit the following characteristics in equilibrium they borrow from and lend to large groups of agents they produce information about investment projects and they issue claims that have different state contingent payoffs than claims issued by ultimate borrowers

does the preference reversal phenomenon necessarily contradict the independence axiom one of the most puzzling paradoxes in decision theory is the preference reversal phenomenon this phenomenon seems to contradict the transitivity axiom for a long time one of the cornerstones of utility theory this paradox is established whenever a decision maker prefers lottery x to lottery y but is willing to put a lower selling price on x than on y such experiments first reported by harold lindman 1971 and sarah lichtenstein and paul slovic 1971 were repeated by david grether and charles plott 1979 werner pommerehne et al 1982 and robert reilly 1982 although the later researchers improved the mechanism through which the selling price emerges they all found systematic reversals a new approach to this problem was developed by charles holt 1986 and edi karni and zvi safra 1987 from two different starting points these authors showed that the preference reversal phenomenon does not necessarily prove a violation of the transitivity axiom as it may contradict the independence axiom this implies that people do not maximize expected utility but in that case the preference reversal phenomenon becomes just another evidence against expected utility theory but not against the transitivity axiom these results have their own disadvantages although the independence axiom is not as fundamental as transitivity it is nevertheless very appealing on normative grounds of course the preference reversal phenomenon necessarily contradicts at least one of the assumptions of expected utility theory but empirical evidence shows that despite its normative appeal violations of the reduction of compound lotteries axiom may happen see for example joshua ronen 1971 and doug snowball and clif brown 1979 in this paper i therefore suggest a decision mechanism for the preference reversals lotteries which is transitive and satisfies the independence axiom but not the reduction axiom

world war ii and convergence proxies that measure the effect of world war ii on a country s capital stock are used as instruments for estimating standard cross country growth regressions the war s destruction should offer a natural experiment that allows us to consistently estimate the speed at which productivity growth converges to its long run path this paper presents evidence that convergence rates are approximately 4 to 6 per annum substantially larger than conventional wisdom

growth and income inequality in south africa abstract this paper uses a multi region endogenous growth model to analyze the competing claims of income growth and income distribution in south africa the study makes a case for the use of redistributive taxes to offset limited capital mobility between high and low income regions to promote both greater income growth and greater income equality market based capital mobility is limited because low income regions are typically characterized by low levels of both physical and human capital which offer little incentive to outside investors the model estimates annual cross regional convergence rates at

precautionary saving of chinese and u s households we employ a model of precautionary saving to study why household saving rates are high in china and low in the united states the use of recursive preferences gives a convenient decomposition of saving into precautionary and nonprecautionary components over 80 of china s saving rate and nearly all u s saving arises from the precautionary motive the difference between u s and chinese household income growth rates is vastly more important than income risk for explaining the saving rates the key mechanism is that precautionary savers have target wealth to income ratios and rapid income growth necessitates high saving rates to maintain the ratio

only income diverges a neoclassical anomaly the neoclassical growth model ngm is only consistent with the absolute divergence in output levels we observe if some determinants of steady state income are also diverging in this paper we show that accumulation rates of physical and human capital are actually significantly converging as are openness to trade and several variables measuring institutional quality output divergence in the face of input policy and institutional convergence is a deep anomaly for the ngm

poverty voracity and growth abstract this article investigates economic performance when enforceable property rights are missing and basic needs matter for consumption it suggests a new view of the so called voracity effect according to which windfall gains in productivity induce behavior that leads to lower economic growth taking into account that the rate of intertemporal substitution in consumption depends on the level of consumption it is shown that voracious behavior is situation specific it occurs when an economy is in decline and sufficiently close to stagnation

intertemporal and intratemporal substitution and the speed of convergence in the neoclassical growth model abstract this paper re examines the speed of convergence in a one sector growth model under fairly general conditions with respect to both production and preferences we investigate the response of the rate of convergence to the intratemporal elasticity of substitution in production and to the intertemporal and intratemporal elasticities of substitution in consumption the speed of convergence is highly sensitive to the first two elasticities but not to the third which is reflected primarily in the agent s labor leisure choice small deviations in the elasticities from standard benchmark parameters can lead to significant variations in the rate of convergence encompassing the range of typical empirical estimates

are there dynamic gains from a poor area development program poor area development programs in which the government transfers extra resources to unusually poor areas have been widely used to fight poverty there has been some research on such programs but little is known about their impact on household living standards over time the authors address the issue for a sizable poor area development program in rural china china s program had a significant impact on rural living standards in the targeted areas of the sample the consumption growth model suggests that households living in the targeted areas had a higher rate of consumption growth than one would have otherwise expected nonetheless the authors found that while the gains in growth were enough to prevent an absolute decline in average living standards they were not enough to reverse the strong underlying divergent tendencies in the rural economy

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

financial intermediary capital we propose a dynamic theory of financial intermediaries that are better able to collateralize claims than households that is have a collateralization advantage intermediaries require capital as they have to finance the additional amount that they can lend out of their own net worth the net worth of financial intermediaries and the corporate sector are both state variables affecting the spread between intermediated and direct finance and the dynamics of real economic activity such as investment and financing the accumulation of net worth of intermediaries is slow relative to that of the corporate sector the model is consistent with key stylized facts about macroeconomic downturns associated with a credit crunch namely their severity their protractedness and the fact that the severity of the credit crunch itself affects the severity and persistence of downturns the model captures the tentative and halting nature of recoveries from crises

capital labor substitution and equilibrium indeterminacy empirical evidence indicates that the elasticity of capital labor substitution for the aggregate u s economy is below unity in contrast the existing indeterminacy literature has mostly restricted attention to a cobb douglas production function which imposes a substitution elasticity exactly equal to unity this paper examines the quantitative relationship between capital labor substitution and the conditions needed for equilibrium indeterminacy and belief driven fluctuations in a one sector growth model with variable capital utilization the substitution elasticity has little quantitative impact on the minimum degree of increasing returns needed for indeterminacy however when capital utilization is constant a below unity substitution elasticity sharply raises the minimum degree of increasing returns in this version of the model lower substitution elasticities impose a higher adjustment cost on labor hours that cannot be mitigated by shifts in the capital utilization rate overall our results show that empirically plausible departures from the cobb douglas specification can make indeterminacy more difficult to achieve

new estimates of the elasticity of marginal utility for the uk this paper provides novel empirical evidence on the value of the elasticity of marginal utility eta for the united kingdom eta is a crucial component of the social discount rate sdr which determines the inter temporal trade offs that are acceptable to society using contemporaneous and historical data new estimates are obtained using four revealed preference techniques the equal sacrifice income tax approach the euler equation approach the frisch additive preferences approach and risk aversion in insurance markets a meta analysis indicates parameter homogeneity across approaches and a central estimate of 1 5 for eta the confidence interval excludes unity the value used in official guidance by the uk government the term structure of the sdr is then estimated the result is a short run sdr of 4 5 declining to 4 2 in the very long run this is higher and flatter than the uk official guidance the difference stems from incorrect calibration of social welfare and estimation of the diffusion of growth other things equal the results suggest that current uk guidance might need to be updated

information reliability and a theory of financial intermediation this paper is an analysis of when it will be beneficial for agents engaged in the production of information to form coalitions the model is cast in a financial market framework thus leading to an identification of conditions sufficient for the existence of financial intermediaries intermediation is shown to improve welfare if informational asymmetries are present and the information generated to rectify these asymmetries is potentially unreliable the usual appeal to transactions costs to explain intermediation is not needed

economic growth effects of alternative climate change impact channels in economic modeling despite increasing empirical evidence of strong links between climate and economic growth there is no established model to describe the dynamics of how different types of climate shocks affect growth patterns here we present the first comprehensive comparative analysis of the long term dynamics of one time temporary climate shocks on production factors and factor productivity respectively in a ramsey type growth model damages acting directly on production factors allow us to study dynamic effects on factor allocation savings and economic growth we find that the persistence of impacts on economic activity is smallest for climate shocks directly impacting output and successively increases for direct damages on capital loss of labor and productivity shocks related to different responses in savings rates and factor specific growth recurring shocks lead to large welfare effects and long term growth effects directly linked to the persistence of individual shocks endogenous savings and shock anticipation both have adaptive effects but do not eliminate differences between impact channels or significantly lower the dissipation time accounting for endogenous growth mechanisms increases the effects we also find strong effects on income shares important for distributional implications this work fosters conceptual understanding of impact dynamics in growth models opening options for links to empirics

habit persistence and the long run labor supply standard macroeconomic models possess the undesirable feature that people stop working in the long run assuming standard parameters the neoclassical model predicts that 2 of annual productivity growth leads to a 99 decline in the labor supply after 624 years yet this contradicts the fact that labor hours per capita are relatively stable even over a long period of time this paper shows how internal and external habit persistence each work to stabilize the long run labor supply independent of key parameter choices

consumption wealth and finite horizons tests of ricardian equivalence i introduction a continuing debate in macroeconomics concerns the ability of fiscal policy to affect aggregate demand in other words if the government reduces taxes and finances a given level of government spending by issuing new bonds does it generate an increase in aggregate demand the answer to this question depends on the degree to which consumers treat government debt as net wealth under the textbook model the tax cut would raise current disposable income and cause consumers to increase spending while this spending increase may be offset to some extent by the effects of higher interest rates the net effect would be an increase in aggregate demand in contrast under ricardian equivalence interest in which was rekindled by barro s 1974 seminal paper permanent income consumers who are connected to future generations by operative inter generational transfers would not consider the current tax cut and increase in disposable income as permanent they would recognize that the government s intertemporal budget constraint implies that for a given level of government spending a tax cut now implies a tax increase in the future under certain conditions one of which is the assumption of infinite planning horizons see sweeney 1988 for a discussion of the potential importance of this and other conditions imposed in barro s model the present value of the future tax increase implied by the current tax cut would exactly equal the present value of the concomitant increase in government debt as a result consumers will save their increased disposable income to cover their future taxes and the tax cut will not affect aggregate demand put differently consumers would not treat government bonds as net wealth although many empirical tests of the ricardian proposition have appeared in the literature see seater 1993 and the literature cited therein most have used somewhat ad hoc estimating equations that do not properly nest the ricardian hypothesis with a reasonable alternative hypothesis it was not until blanchard s 1985 elegant representation of the behavior of consumers with finite planning horizons that a clear path for empirical work was delineated blanchard s paper spawned a series of empirical papers designed to test ricardian equivalence within the framework of his model which does nest both the ricardian hypothesis and a non ricardian alternative in a widely cited paper evans 1988 was the first to derive the empirical implications of blanchard s model the model reduces the test of ricardian equivalence to a test of whether wealth affects current consumption after accounting for the effect of consumption in the previous period if it does then the model implies that consumers have finite planning horizons and treat government bonds as net wealth although evans s results cannot reject ricardian equivalence they do not resolve the controversy about the ricardian hypothesis other equally well grounded empirical studies e g graham and himarios 1991 and references therein find results that favor the finite horizon interpretation in the first part of the paper we re estimate evans s 1988 model using a better approximation of the market value of wealth contrary to evans s conclusions we find that ricardian equivalence should be rejected in favor of a non ricardian alternative hypothesis in which consumers have finite planning horizons 1 our results differ from evans s primarily because our wealth measure takes account of available information on the market value of corporate equity held by households our series is markedly more volatile than evans s as a result of the decidedly larger movements in the market relative to the book value of corporate assets in the second part of the paper we test whether the long run properties of the data are consistent with our regression results in contrast to earlier work by gali 1990 we find that they are

two level ces production technology in the solow and diamond growth models the two level ces aggregate production function that nests a ces into another ces function has recently been used extensively in theoretical and empirical applications of macroeconomics this paper examines its theoretical properties and establishes existence and stability conditions of equilibria under the solow and diamond growth models in addition it examines the efiect of changes in substitution parameters on transitional growth and steady states it is shown that in the solow model the su cient condition for a steady state is fulfllled for a larger range of substitution parameter values than with the basic ces function in the diamond model an increase in substitution parameters results in higher transitional growth under weaker conditions than with the basic ces function

how misleading is linearization evaluating the dynamics of the neoclassical growth model this paper investigates the reliability of employing linearization to evaluate the dynamic adjustments to changes in productive government spending in a ramsey growth model if government expenditure is introduced as a flow and the dynamic adjustment is fast linearization may yield a reasonably good approximation to the true dynamics even for fairly large policy shocks if government expenditure assumes the form of a stock leading to more sluggish adjustment linearization may yield misleading predictions these errors occur at the beginning of the transition and weigh heavily in welfare calculations the implications for temporary shocks and the speed of convergence are also considered

income convergence among u s states cross sectional and time series evidence we perform convergence tests on the u s states for per capita income from 1930 to 2009 cross sectional tests support overall convergence and convergence but may not hold true for the last three decades time series tests suggest that about half of the states exhibit stochastic convergence and of these all are also converging probit regressions reveal that the likelihood a state is converging is a function of changing capital to labour ratios the size of the agricultural sector and levels of taxation and tax revenue regional disparities in convergence remain among the southern and midwestern states convergence des niveaux de revenus entre les etats americains resultats a partir de donnes transversales et de series chronologiques on presente des tests de convergence des revenus per capita des etats americains entre 1930 et 2009 les tests transversaux supportent l hypothese de convergence de type et de type mais pourraient ne pas tenir pour les trois dernieres decennies les tests utilisant les series chronologiques suggerent que la moitie des etats montrent une convergence stochastique et que de ceux ci tous supportent l hypothese de convergence de type des regressions par la methode probit revelent que la vraisemblance qu un etat converge depend des rapports capital travail changeants de la taille du secteur agricole et des niveaux de taxation et de rentrees fiscales des disparites regionales dans la convergence demeurent entre les etats du sud et du midwest

a macroeconomic model with a financial sector this paper studies a macroeconomic model in which financial experts borrow from less productive agents we pursue four sets of results i the economy is prone to instability and occasionally enters volatile episodes as volatility spikes agents precautionary motive increases depressing prices even further log linear approximations fail to capture these non linear effects that can cause economies to be significantly depressed for long periods of time ii endogenous risk during volatile episodes increases asset price correlations iii financial experts impose a negative externality on each other and on the labor sector by not maintaining adequate capital cushion and funding structure iv while risk sharing within the financial sector through securitization and derivatives contracts reduces many inefficiencies it can also amlify systemic risks

a politico economic theory of income redistribution this study integrates models of income redistribution developed by economists who suggest that citizens voluntarily redistribute because of interdependent preferences and rely on the state for implementation owing to the public good nature of redistribution and political scientists who focus on conditions that lead to demands that the state intervene to assist the poor and on the development of institutions that facilitate such demands we propose a testable theory of redistribution and apply it to data from the american states the empirical analysis addresses determinants of the aid to families with dependent children guarantee adjusted for medicaid and food stamps to which a family receiving the guarantee would be entitled we posit significant links between the guarantee and both observable explanatory variables such as per capita income and latent constructs such as liberal party control we specify observable indicators for the latent constructs and use the lisrel method to estimate parameters for the indicators and structural coefficients the findings show that both political and economic variables significantly affect the level of the guarantee

fiscal policy elastic labor supply and endogenous growth abstract endogenizing labor supply leads to fundamental changes in the equilibrium structure of the ak growth model the balanced growth equilibrium can be described in terms of two tradeoff loci relating the equilibrium growth rate to the fraction of time devoted to leisure the implications of endogenous labor supply for fiscal policy are analyzed three issues are addressed first the effects of various distortionary tax changes and government expenditure changes on the equilibrium growth leisure employment tradeoff are analyzed second optimal fiscal policy is characterized finally the formal analysis is supplemented by numerical results focusing particularly on the quantitative welfare implications

macroeconomic performance and convergence in oecd countries abstract this paper investigates the robustness of the correlation between growth and a set of variables which comprises accumulation rates in human and physical capital and medium term macroeconomic indicators in oecd countries we include these variables as additional regressors in the standard growth equation that comes from the human capital augmented solow model our results show that variables related to medium term macroeconomic performance affect both growth and convergence in some periods these variables even outperform the explanatory power of the conventional growth variables such as the accumulation rates our results also suggest that it is difficult to analyse the contribution to growth of any particular macroeconomic indicator in an isolated way rather these effects should be studied in a framework that accounts for the macroeconomic performance of a country

lower class mobilization and policy linkage in the u s states theory political participation by lower class voters should create pressures for government to respond with supportive policies hypotheses lower class voting is associated with more generous state welfare policies political forces and institutions structure this relationship methods a pooled time series analysis for the 50 u s states from 1978 to 1990 results we demonstrate an enduring relationship between the degree of mobilization of lower class voters and the generosity of welfare benefits provided by state governments this relationship can be vitiated by remarkable political and economic events such as the new federalism and the economic recession in the early 1980s finally the importance of lower class mobilization for redistributive policy is enhanced by the liberalism and competitiveness of state democratic parties

aggregate consumption behaviour and liquidity constraints the canadian evidence this paper considers a general permanent income model in which a fraction of consumers in the economy is liquidity constrained consumption growth rate for these individuals is related to the growth rate of their income and the level of real interest rates the interest rate coefficient is predicted to be smaller in the presence of liquidity constraints empirically liquidity constraints are found to be important and the estimated intertemporal elasticity of substitution parameter is much larger than the one obtained by estimating the standard representative agent model lastly there is some evidence of structural changes over the sample period which are associated with the 1982 recession

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

robustness tests of the augmented solow model this paper demonstrates some techniques for testing the robustness of cross section and panel data regressions and applies them to the influential augmented solow growth model the paper focuses on robust estimation and analysis of sensitivity to measurement error in particular it is shown that estimated technology parameters and convergence rates are highly sensitive to measurement error 1998 john wiley sons ltd

a model of capital and crises we develop a model in which the capital of the intermediary sector plays a critical role in determining asset prices the model is cast within a dynamic general equilibrium economy and the role for intermediation is derived endogenously based on optimal contracting considerations low intermediary capital reduces the risk bearing capacity of the marginal investor we show how this force helps to explain patterns during financial crises the model replicates the observed rise during crises in sharpe ratios conditional volatility correlation in price movements of assets held by the intermediary sector and fall in riskless interest rates

politics institutions and welfare spending in industrialized democracies 1960 82 electoral turnout as well as left and center governments increase welfare effort that the welfare efforts of governments led by particular types of parties show significant differences and vary notably with the strength of oppositional and junior coalitional parties and that relatively neocorporatist centralized and traditionalistic polities are high on welfare effort overall our findings suggest that contrary to many claims both partisan and nonpartisan facets of democratic politics and political institutions shape contemporary social welfare effort

distributional dynamics in a neoclassical growth model the role of elastic labor supply we examine the evolution of the distributions of wealth and income in a ramsey model in which agents differ in their initial capital endowment and where the labor supply is endogenous the assumption that the utility function is homogeneous implies that the macroeconomic equilibrium is independent of the distribution of wealth and allows us to characterize fully income and wealth dynamics we find that although the dynamics of the distribution of wealth are similar under fixed and flexible labor those of the income distribution are not in response to a structural change income inequality may move in opposite ways depending on whether or not the labor supply is fixed

abstention in elections with asymmetric information and diverse preferences we analyze a model of a two candidate election with costless voting in which voters have asymmetric information and diverse preferences we demonstrate that a strictly positive fraction of the electorate will abstain and that nevertheless elections effectively aggregate voters private information using examples we show that more informed voters are more likely to vote than their less informed counterparts increasing the fraction of the electorate that is informed however may lead to higher levels of abstention we conclude by showing that a biased distribution of information can lead to a biased voting population but does not lead to biased outcomes

budget balance welfare and the growth rate dynamic scoring of the long run government budget this paper determines conditions under which a reduction in the role of government either through a tax cut alone or together with accompanying expenditure cuts will improve long run government fiscal balance for a ceteris paribus cut in the income tax rate to improve long run government balance the intertemporal elasticity of substitution must exceed unity a tax cut balanced by an expenditure cut is likely to improve the long run balance even if it does not improve the short run balance the relationship between improving the long run fiscal balance and economic welfare is also analyzed

risk sharing within the united states what do financial markets and fiscal federalism accomplish we measure income uncertainty at the level of u s states and the extent to which it has been reduced through risksharing using a method recently developed by athanasoulis and van wincoop 2000 risk is measured as the standard deviation of state specific income growth uncertainty measured by using the error term of a regression of income growth on variables in the information set risk sharing is measured by the extent to which this standard deviation has been reduced through financial markets and federal fiscal policy the advantage of this measure over the existing risk sharing literature is that the interpretation does not depend on many auxiliary assumptions our findings on the extent of risk sharing are insensitive to the only assumption we need to make the variables that are in the information set we find that the standard deviation of state specific income growth uncertainty is reduced by less than half through financial markets and federal fiscal policy we show that the extent of risk sha

the intertemporal elasticity of substitution in consumption in the united states and the united kingdom as robert e hall 1988 notes the magnitude of the intertemporal elasticity of substitution in consumption is one of the central questions of macroeconomics do higher expected real interest rates lead to deferred consumption the authors extend hall s methodology and model and compare results for the united sta tes and the united kingdom in both cases they directly estimate the mo ving average process that temporal aggregation might induce in the random disturbances and take account of consumers who do not follow the lif e cycle permanent income model of consumption copyright 1992 by mit press

capital utilization economic growth and convergence abstract optimal decisions by economic agents regarding the utilization of capital lead to empirically plausible speeds of convergence in one sector models of economic growth the relationship between depreciation and capital utilization plays a crucial role in slowing down convergence to the steady state cross country differences in the extent to which the capital utilization decision is internalized along the transition path may lead to differences in convergence rates even for countries with similar initial and terminal conditions finally by assuming a constant depreciation rate and full capital utilization standard growth models may be overstating the magnitude of the steady state equilibrium

cross sectional regressions and the empirics of economic growth abstract this paper provides a short survey of the recent empirical growth literature based on cross sectional analysis unlike some other analysts i argue that this literature has uncovered interesting findings that should direct theoretical research in the future

does political knowledge increase turnout evidence from the 1997 british general election a number of recent formal models predict a positive effect of political knowledge on turnout both information acquisition and turnout however are likely to be determined by a similar set of variables rendering hard the identification of a causal link in empirical investigations available empirical regularities should therefore be interpreted as mere correlations i address this problem by using an intrumental variables approach where the instruments are represented by various proxies of information supply on mass media using survey data from the 1997 british general election study i show that political knowledge has a sizeable influence on the probability of voting and that mass media play an important role in influencing political participation

consumption innovation persistence and the excess smoothness debate based on studies using us data consumption is too smooth relative to the implications of the rational expectations permanent income hypothesis repih of consumption we examine this and a number of related methodologicalissues for the uk using maximum likelihood estimation mle of an autoregressive fractionally integrated moving average arfima model of the income process we conclude that an innovation to income has a persistent effect on consumption and that in contrast to the findings from us studies consumption is too volatile compared to the repih model further mle is substantially more efficient than the semi parametric method of estimating arfima models which has previously been used in this area

american federalism welfare policy and residential choices the relationship between welfare benefit levels and the residential choices of the poor raises two issues for federalism in the united states do state benefit levels affect the residential choices of the poor do residential choices of the poor affect the level at which a state sets its benefit levels empirical studies have seldom studied the interconnection between these two issues this research estimates simultaneously the mutual effects of welfare benefits and poverty rates while controlling for other economic and political variables when benefit levels become high the size of the poverty population increases conversely when poverty rates become high benefit levels are cut the findings are consistent with the claim that state determined benefit levels distort policy and residential choices

education and income growth implications for cross country inequality this paper examines the extent to which patterns of human capital convergence can account for observed patterns of income inequality between countries to do this i decompose national income into three components one due to education levels one reflecting the return to education and a residual component i then examine in turn the contribution of each of them to changes in income dispersion among the developed countries convergence in education levels has resulted in a reduction in income dispersion however for the world as a whole incomes have diverged despite substantial convergence in education levels this is a result of increases in the return to education that favor the developed countries at the expense of the less developed countries

international and domestic collateral constraints in a model of emerging market crises abstract we build a model of emerging markets crises which features two types of collateral constraints firms in a domestic economy have limited borrowing capacity from international investors they also have limited borrowing capacity with respect to each other we study how the presence and changes in these collateral constraints affect financial and real variables a binding international constraint in the aggregate leads to a sharp rise in interest rates and fire sales of domestic assets while limited domestic collateral can lead to wasted international collateral these two collateral constraints can interact in important ways the first is disintermediation a fire sale of domestic assets causes banks to fail in their function of reallocating resources across the economy leading to wasted international collateral the second is a dynamic effect we show that firms in an economy with limited domestic collateral and a binding international collateral constraint will not adequately precaution against adverse shocks increasing the severity of these shocks

how fast do economics converge the conventional approach to estimating how fast economics converge examines the cross economy relationship between the growth rate of per capita output over some time period and its initial level this approach produces consistent estimates only under highly restrictive assumptions which are violated by the data the paper develops an alternative approach that produces consistent estimates under weak assumptions this approach yields estimates substantially larger than those reported in the literature and also sufficiently large to be broadly consistent with the predictions of neoclassical growth theory

consumption retirement and social security evaluating the efficiency of reform that encourages longer careers abstract this paper proposes and analyzes a social security reform in which individuals no longer face the oasi payroll tax after say age 54 or a career of 34 years and their subsequent earnings have no bearing on their benefits we first estimate parameters of a life cycle model our specification includes non separable preferences and possible disability it predicts a consumption expenditure change at retirement we use the magnitude of the expenditure change together with households retirement age decisions to identify key structural parameters the estimated magnitude of the change in consumption expenditure depends importantly on the treatment of consumption by adult children of the household simulations indicate that the reform could increase retirement ages one year or more equivalent variations could average more than 4000 per household and income tax revenues per household could increase by more than 14 000

re examination of convergence hypothesis among indian states in panel stationarity testing framework with structural breaks abstractthis article examines the conditional income convergence hypothesis for 17 major states in india for the period of 1960 2012 univariate stationarity tests without structural breaks provide evidence against the convergence hypothesis however when two or more structural breaks are applied in per capita income series the incomes of around 11 13 states are found to stochastically converge to the national average this finding supports the convergence hypothesis for the panel as a whole after accounting for two data features cross sectional dependence and structural breaks in incomes using a unified panel stationarity testing framework

interaction between knowledge and technology a contribution to the theory of development this article attempts to explain the large and persistent disparities in levels of output per worker across countries it is argued that an explanation for these disparities requires an understanding of the relationship between knowledge and technology the model that is constructed can be summarized as an open economy version of the solow swan growth model in which technological change is investment specific and knowledge about new technologies is embodied in labour in the model income differences arise because poor countries lack the knowledge to implement foreign technologies productively furthermore these disparities persist when countries differ in their ability to learn jel

social policy responsiveness in developed democracies do mass policy preferences influence the policy output of welfare states in developed democracies this is an important issue for welfare state theory and research and this article presents an analysis that builds from analytical innovations developed in the emerging literature on linkages between mass opinion and public policy the authors analyze a new dataset combining a measure of social policy preferences with data on welfare state spending alongside controls for established causal factors behind social policy making the analysis provides evidence that policy preferences exert a significant influence over welfare state output guided also by statistical tests for endogeneity the authors find that cross national differences in the level of policy preferences help to account for a portion of the differences among social christian and liberal welfare state regimes the results have implications for developing fruitful connections between welfare state scholarship comparative opinion research and recent opinion policy studies

the transitional dynamics of fiscal policy long run capital accumulation and growth this paper analyzes the effects of fiscal policies in a non scale growing economy with public and private capital the equilibrium dynamics are characterized and we contrast the dynamic effects of government expenditure on investment and expenditure on consumption under four alternative modes of tax financing most of our attention focuses on the numerical simulations of a calibrated economy the results emphasize the lengthy transition periods which implies that policies have sizeable level effects leading to substantial welfare effects even though long run growth rates are unaffected the paper highlights the intertemporal dimensions of fiscal policy and the tradeoffs these involve for economic performance especially growth and welfare

recovery from financial crises evidence from 100 episodes we examine the evolution of real per capita gdp around 100 systemic banking crises part of the costs of these crises owes to the protracted nature of recovery on average it takes about eight years to reach the pre crisis level of income the median is about 6 years five to six years after the onset of crisis only germany and the us out of 12 systemic cases have reached their 2007 2008 peak in real income forty three percent of the 100 episodes recorded double dips post war business cycles are not the relevant comparator for the recent crises in advanced economies

what determines the elasticity of substitution between capital and labor a literature review this paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor our focus is on the two input constant elasticity of substitution ces production function we start by presenting four concise observations that summarize the empirical literature on the estimation of motivated by these observations the main part of this survey then focuses on potential determinants of capital labor substitution we first review several approaches to the microfoundation of production functions where the elasticity of substitution eos is treated as a purely technological parameter second we outline the construction of an aggregate elasticity of substitution aes in a multi sectoral framework and investigate its dependence on underlying intra and inter sectoral substitution third we discuss the influence of the institutional framework on the extent of factor substitution overall this survey highlights that the effective elasticity of substitution ees which is typically estimated in empirical studies is generally not an immutable deep parameter but depends on a multitude of technological non technological and institutional determinants based on these insights the final section identifies a number of potential empirical and theoretical avenues for future research

federal state and local governments evaluating their separate roles in us growth we use us county level data from 1970 to 1998 to explore the relationship between economic growth and government employment at three levels federal state and local increases in federal state and local government employments are all negatively related to economic growth we find no evidence that government is more efficient at lower levels while we cannot separate out the productive and redistributive services of government we document that the county level income distribution became slightly more unequal from 1970 to 1998 we conclude that a release of government employed labor inputs to the private sector would be growth enhancing

regional convergence and common stochastic long run trends a re examination of the us regional data the paper utilizes modern econometric techniques organized around i 1 and cointegration analysis to examine the number of common stochastic long run trends in regional incomes and assess the hypothesis of regional convergence for the us over the period 1929 1997 time series evidence is conflicting but tends to indicate the presence of too many common stochastic long run trends thus providing no support for the convergence hypothesis l article emploie des techniques econometriques recentes basees sur des analyses i 1 et cointegree afin d examiner le nombre de tendances communes stochastiques a long terme des revenus regionaux et d evaluer l hypothese qui avance la notion de la convergence regionale aux etats unis sur la periode qui va de 1929 a 1997 des preuves presentees en serie temporelle s averent contradictoires mais semblent indiquer la presence d un nombre trop eleve de tendances communes stochastiques a long terme ce qui ne vient pas a l appui de l hypothese qui avance la notion de conv

is consumption too smooth the case of the united kingdom this study consider whether for the uk the restrictions of the rational expectations permanent income repi model of consumption are consistent with the data and whether consumption is too smooth given innovations in labour income some of the findings confirm those for the usa the repi restrictions are rejected however in marked contrast to the result of campbell and deaton 1989 little is found to support the view that consumption is too smooth indeed there is some support for the view that consumption is too volatile some insight is given as to how such results can arise

lower class mobilization and policy linkage in the u s states a correction hill leighley and hinton andersson 1995 report a series of empirical analyses intended to test four hypotheses about the association between lower class mobilization and public policies in the american states those hypotheses are 1 the higher the turnout of the lower class the more liberal is state welfare policy 2 the higher economic and fiscal stress the lower the association between lower class turnout and welfare policy 3 liberal party control of state government is the linkage mechanism that relates lower class mobilization to policy and 4 party competition is the linkage mechanism that relates lower class mobilization to policy in this note we explain how the incorrect handling of missing data in those original analyses led to an erroneous conclusion about the third hypothesis test an incorrect sign reported for one control variable in the first two hypothesis tests and small changes in the significance of a few other control variables we explain the cause of the errors report corrected analyses and close with brief observations about the theoretical and practical implications of the correct empirical results the error in the original analyses arose because missing data codes for three variables in a cross sectional data set originally created in spssx were interpreted as valid values when the data set was expanded into a pooled cross sectional time series design and analyzed with the microcrunch software package those three variables were for state party competition mass political liberalism and state party elite liberalism and the missing data affect four states thus the missing data values biased the coefficients reported for these variables in the original analyses the optimal procedures for handling such missing data problems are unsettled bartels and brady 1991 136 7 for the purposes of this note we report analyses that are conservative by some but not all criteriaanalysis of only those cases with complete data on the variables under study this procedure appears especially appropriate in light of the absence of a consensus on an alternative one and the small percentage of total cases eliminated from consideration by the procedure in the present instance

the intertemporal elasticity of substitution an exploration using a us panel of state data this paper uses state level consumption data to estimate the intertemporal elasticity of substitution of consumption ies in contrast to the results of hall 1988 and campbell and mankiw 1989 we provide evidence indicating that the ies is significantly different from zero and probably close to one since inference about the ies in the context of the standard euler equation is problematic as a result of mis specification bias we cast most of our discussion in the context of the framework developed by campbell and mankiw this modifies the euler equation in that a fraction of agents simply consume their income the use of panel data to examine the relationship between interest rates and consumption growth has two advantages first we achieve a significant increase in precision which in particular allows us to rule out a zero ies second we can use the panel aspect of the data to bypass asset return measurement problems in particular we identify a common time component in expected consumption growth that is associated with movements in interest rates when the ies is positive

foreign aid and economic growth the role of flexible labor supply this paper examines the link between foreign aid economic growth and welfare in a small open economy external transfers impinge on the recipient s macroeconomic performance by affecting resource allocation decisions and relative prices the endogeneity of the labor leisure choice plays a crucial role in the propagation of foreign aid shocks the efficacy of foreign aid also depends on externalities associated with the public good that it helps finance the impact of tied and untied aid on the recipient government s intertemporal fiscal balance is examined finally the transitional adjustment to a foreign aid shock is shown to be sensitive to the elasticity of substitution in production and the relative importance of the labor leisure choice in utility

taxation and income distribution dynamics in a neoclassical growth model we examine how changes in tax policies affect the dynamics of the distributions of wealth and income in a ramsey model in which agents differ in their initial capital endowment the endogeneity of the labor supply plays a crucial role in determining inequality as tax changes that affect hours of work will affect the distribution of wealth and income reinforcing or offsetting the direct redistributive impact of taxes our results indicate that tax policies that reduce the labor supply are associated with lower output but also with a more equal distribution of after tax income we illustrate these effects by examining the impact of recent tax changes observed in the us and in european economies

how does labor mobility affect income convergence abstract labor mobility is introduced into the neoclassical growth model for a small open economy with capital intensity below its steady state level outmigration directly contributes to faster income convergence but also creates a disincentive for gross capital investment at low relative income levels the latter disincentive effect tends to dominate so that labor mobility can actually slow the speed of income convergence

the speed of convergence and alternative government financing abstract in this paper we are concerned with the speed of convergence in the sidrauski monetary optimizing model sidrauski am econ rev 57 1967 534 in which the steady state capital stock is not influenced by a change in public spending the paper studies how different the speed of convergence to the steady state is affected by a change in government spending under the various ways of financing in exploring the transitional adjustment to the public policy shock it will be convenient to focus upon the degree of relative risk averse

distribution and mobility of wealth of nations we estimate the empirical bimodal cross section distribution of real gross domestic product per capita of 120 countries over the period 1960 1989 by a mixture of a weibull and a truncated normal density the components of the mixture represent a group of poor and a group of rich countries while the mixing proportion describes the distribution over poor and rich this enables us to analyse the development of the mean and variance of both groups separately and the switches of countries between the two groups over time empirical evidence indicates that the means of the two groups are diverging in terms of levels but that the growth rates of the means of the two groups over the period 1960 1989 are the same

financial liberalization and aggregate consumption the evidence from taiwan this paper considers the effect of financial liberalization on aggregate consumption with a special focus on taiwan which has sustained a high savings rate and a rapid rate of economic growth under financial dualism but has undertaken financial liberalization since the 1980s leading to an expansion of the formal financial sector the paper finds that because of an active informal financial sector consumers in taiwan are less credit constrained than in other developing countries however the expansion of the formal financial sector has contributed to some relaxation of consumer credit constraints and thereby changes in the income and interest elasticities of consumption it also has brought about a higher consumption growth rate offsetting at least partially the positive growth effect of financial liberalization which helps improve the efficiency in finanacial intermediation

debt constrained asset markets we develop a theory of general equilibrium with endogenous debt limits in the form of individual rationality constraints similar to those in the dynamic consistency literature if an agent defaults on a contract he can be excluded from future contingent claims markets trading and can have his assets seized he cannot be excluded from spot markets trading however and he has some private endowments that cannot be seized all information is publicly held and common knowledge and there is a complete set of contingent claims markets since there is complete information an agent cannot enter into a contract in which he would have an incentive to default in some state in general there is only partial insurance variations in consumption may be imperfectly correlated across agents interest rates may be lower than they would be without constraints and equilibria may be pareto ranked

convergence speed and preference externalities in a one sector model with elastic labor supply abstract in a one sector model with elastic labor supply where consumption and leisure externalities are incorporated we examine the impact of preference externalities on convergence speed
