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

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

comovements in national stock market returns evidence of predictability but not cointegration abstract this paper is a response to the literature that tests for cointegration between national stock market indices it argues that apparent findings of cointegration in other studies may often be due to the use of asymptotic rather than small sample critical values in fact economic theory suggests that cointegration is unlikely to be observed in efficient markets however this paper finds evidence for the predictability of relative returns and the existence of a winner loser effect across 16 national equity markets a conclusion is that national stock market indices include a common world component and two country specific components one permanent and one transitory

racing to the bottom or climbing to the top economic globalization and collective labor rights this article explores the impact of economic globalization on workers rights in developing countries the authors hypothesize that the impact of globalization on labor rights depends not only on the overall level of economic openness but also on the precise ways in which a country participates in global production networks using a new data set on collective labor rights the authors test these expectations their analysis of the correlates of labor rights in 90 developing nations from 1986 to 2002 highlights globalization s mixed impact on labor rights as climb to the top accounts suggest foreign direct investment inflows are positively and significantly related to the rights of workers but at the same time trade competition generates downward race to the bottom pressures on collective labor rights the authors also find that domestic institutions and labor rights in neighboring countries are important correlates of workers rights

revenue substitution how foreign aid inflows moderate the effect of bilateral trade pressures on labor rights summary this paper investigates how foreign aid inflows moderate bilateral trade based pressures on the exporting countries labor rights because aid provides additional resources to recipient governments it reduces the importance aid recipient governments attach to the preferences of their export partners consequently aid inadvertently moderates the leverage exercised by importing countries on the governments of exporting developing countries our analysis of a panel of 91 aid recipient countries for the period 1985 2002 lends support to the revenue substitution hypothesis when aid levels are low bilateral trade based pressures are associated with improved labor rights as aid levels rise however the effect loses significance

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

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

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

trade based diffusion of labor rights a panel study 1986 2002 this article investigates the nature of the linkages between trade and labor rights in developing countries specifically we hypothesize that a california effect serves to transmit superior labor standards from importing to exporting countries in a manner similar to the transmission of environmental standards we maintain that all else being equal the labor standards of a given country are influenced not by its overall level of trade openness but by the labor standards of its trading partners we evaluate our hypothesis using a panel of 90 developing countries over the period 1986 2002 and we separately examine the extent to which the labor laws and the actual labor practices of the countries are influenced by those of their export destinations we find that strong legal protections of collective labor rights in a country s export destinations are associated with more stringent labor laws in the exporting country this california effect finding is however weaker in the context of labor rights practices highlighting the importance of distinguishing between formal legislation and actual implementation of labor rights

political governance civil liberties and human capital evaluating their effect on foreign direct investment in emerging and developing economies we study the influence of a country s political governance on its attractiveness to foreign direct investors we argue that democracy is not a unidimensional concept and that the effect of host country political governance on incoming foreign direct investment fdi differs depending on whether fdi originates from a democratic or an autocratic country we also hypothesize that the effect of civil liberties depends on the motivations of investing multinational enterprises mnes and that human capital moderates this relationship we test our hypotheses on a sample of 35 000 investments in emerging and developing countries between 2003 and 2013

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

does foreign aid promote the expansion of government building on the literature on public finance i seek to advance our understanding of variations in government size by exploring the impact of official development assistance on fiscal policy i hypothesize that foreign aid operates in accordance with the flypaper effect systematically generating incentives and opportunities for the expansion of government spending results from a time series cross sectional regression analysis of growth in government spending over the 1970 99 time period are consistent with the hypothesis for middle and lower income nations aid represents an important determinant of government expansion looking at the tax and revenue side of the equation however reveals a more perverse pattern of response aid promotes not only increased spending but also reduced revenue generation the results have important implications from both a theoretical and policy perspective inter alia they point to the potentially self defeating nature of efforts to promote market oriented programs of state retrenchment via development assistance as well as to the importance of incorporating international transfers into future research on government spending

do natural resources fuel authoritarianism a reappraisal of the resource curse a large body of scholarship finds a negative relationship between natural resources and democracy extant cross country regressions however assume random effects and are run on panel datasets with relatively short time dimensions because natural resource reliance is not an exogenous variable this is not an effective strategy for uncovering causal relationships numerous sources of bias may be driving the results the most serious of which is omitted variable bias induced by unobserved country specific and time invariant heterogeneity to address these problems we develop unique historical datasets employ time series centric techniques and operationalize explicitly specified counterfactuals we test to see if there is a long run relationship between resource reliance and regime type within countries over time both on a country by country basis and across several different panels we find that increases in resource reliance are not associated with authoritarianism in fact in many specifications we generate results that suggest a resource blessing

trading human rights how preferential trade agreements influence government repression a growing number of preferential trade agreements ptas have come to play a significant role in governing state compliance with human rights when they supply hard standards that tie material benefits of integration to compliance with human rights principles ptas are more effective than softer human rights agreements hras in changing repressive behaviors ptas improve members human rights through coercion by supplying the instruments and resources to change actors incentives to promote reforms that would not otherwise be implemented i develop three hypotheses 1 state commitment to hras and 2 ptas supplying soft human rights standards not tied to market benefits do not systematically produce improvement in human rights behaviors while 3 state commitment to ptas supplying hard human rights standards does often produce better practices i draw on several cases to illustrate the processes of influence and test the argument on the experience of 177 states during the period 1972 to 2002 i would like to thank mike colaresi dan drezner david lake lisa martin walter mattli john meyer mark pollack erik voeten jim vreeland and two anonymous reviewers for their detailed and thoughtful comments on various drafts of this manuscript as well as the many other people who have helped me by asking hard questions along the way i would also like to thank michael barnett charles franklin and jon pevehouse for advice during the dissertation research that supports this article and alexander h montgomery for assistance in data management all faults are my own for generous assistance in the collection of data i thank the national science foundation ses 2cdz414 and ses 0135422 john meyer and francisco ramirez for support during the writing of the article i thank nuffield college at oxford university and most importantly lynn eden and stanford s center for international security and cooperation

globalization and the right to free association and collective bargaining an empirical analysis summary economies that are more open to trade and foreign direct investment fdi face greater competitive pressure than closed ones globalization critics are concerned that this pressure induces countries to lower labor standards in order to remain competitive and retain or attract foreign investment defenders of globalization counter that countries that are more closely integrated into global markets are likely to have higher rather than lower standards this article tests the effect of globalization on a specific labor right which forms part of what are commonly regarded as core or fundamental labor standards employing a new measure of free association and collective bargaining rights we find that countries that are more open to trade have fewer rights violations than more closed ones this effect holds in a global sample as well as in a developing country sub sample and holds also when potential feedback effects are controlled via instrumental variable regression the extent of an economy s penetration by fdi has no statistically significant impact globalization might not be beneficial for outcome related labor standards but it is likely to promote the process related standard of a right to free association and collective bargaining

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

globalization and labor conditions working conditions and worker rights in a global economy this book explains how three major mechanisms of globalization international trade international migration and the activities of multinational companies have altered working conditions and labor rights around the world during the 20th century drawing on analyses of a database on international labor conditions assembled for this project and a growing research literature on globalization and labor conditions the book finds that trade migration and multinational companies are associated with improvements in world labor conditions

the perils of unearned foreign income aid remittances and government survival given their political incentives governments in more autocratic polities can strategically channel unearned government and household income in the form of foreign aid and remittances to finance patronage which extends their tenure in political office i substantiate this claim with duration models of government turnover for a sample of 97 countries between 1975 and 2004 unearned foreign income received in more autocratic countries reduces the likelihood of government turnover regime collapse and outbreaks of major political discontent to allay potential concerns with endogeneity i harness a natural experiment of oil price driven aid and remittance flows to poor non oil producing muslim autocracies the instrumental variables results confirm the baseline finding that authoritarian governments can harness unearned foreign income to prolong their rule finally i provide evidence of the underlying causal mechanisms that governments in autocracies use aid and remittances inflows to reduce their expenditures on welfare goods to fund patronage

do economic problems at home undermine worker safety abroad a panel study 1980 2009 do economic downturns in the global north undermine worker safety in the global south literature suggests that bilateral trade linkages lead to the diffusion of good labor standards from importing countries of the global north to exporting countries of the global south the crucial mechanism is the ability and willingness of importing firms to deploy their market leverage and ask for improved labor standards from their overseas suppliers yet cost cutting pressures emanating from economic downturns might lead the same importing firms to give lower priority to worker safety in their overseas supply chains when importing firms demand price reductions overseas suppliers might respond by reducing wages ignoring safety regulations and working their labor force for longer hours the observable implication is that worker safety in the global south may deteriorate during economic downturns in their export markets located in the global north we evaluate our hypothesis using a panel of 83 developing countries for the period during 1980 2009 and find that economic downturns in developed country markets are associated with significant increases in non fatal occupational injury rates in developing countries the injury increasing effect is more pronounced in developing countries with weak workers rights protection

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

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

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

taking time seriously dramatic world change has stimulated interest in research questions about the dynamics of politics we have seen increases in the number of time series data sets and the length of typical time series but three shortcomings are prevalent in published time series analysis first analysts often estimate models without testing restrictions implied by their specification second researchers link the theoretical concept of equilibrium with cointegration and error correction models third analysts often do a poor job of interpreting results the consequences include weak connections between theory and tests biased estimates and incorrect inferences we outline techniques for estimating linear dynamic regressions with stationary data and weakly exogenous regressors we recommend analysts 1 start with general dynamic models and test restrictions before adopting a particular specification and 2 use the wide array of information available from dynamic specifications we illustrate this strategy with data on congressional approval and tax rates across oecd countries

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

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

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

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

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

globalization and the decline of the welfare state in less developed countries why have trends in government welfare spending in developing countries diverged from those in developed countries i address this question by investigating the effects of capital and trade flows on government welfare spending in fifty three developing countries using an original measure of labor power in developing countries i test the links between international markets labor s political strength and the welfare state i argue that labor s collective action problems caused by large populations of low skilled and surplus workers offset labor s potential political gains from globalization i show that when the proportion of low skilled workers in a nation is high globalization will lead to a decline in welfare spending most significantly the results suggest that in nations where labor market institutions are not yet well developed government social welfare spending is constrained by international market forces

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

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

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

a race to the bottom in labor standards an empirical investigation abstract one of the concerns over globalization is that as nations compete for investment they relax labor standards to attract firms using spatial estimation on panel data for 135 countries over 17 years we find that the labor standards in one country are positively correlated with those elsewhere i e a cut in labor standards in other countries reduces labor standards in the country in question this interdependence is more evident in labor practices i e enforcement than in labor laws further while we find evidence of competition in both developed and developing countries it is strongest among developing countries with weak standards
