money and capital abstract the effects of money anticipated inflation on capital formation is a classic issue in macroeconomics previous papers adopt reduced form approaches putting money in the utility function or imposing cash in advance but using otherwise frictionless models we follow instead a literature that tries to be explicit about the frictions making money essential this introduces new elements including a two sector structure with centralized and decentralized markets stochastic trading opportunities and bargaining these elements matter quantitatively and numerical results differ from findings in the reduced form literature the analysis also reduces a gap between microfounded monetary economics and mainstream macro

are any growth theories robust this article investigates the strength of empirical evidence for various growth theories when there is model uncertainty with respect to the correct growth model using model averaging methods we find little evidence that so called fundamental growth theories play an important role in explaining aggregate growth in contrast we find strong evidence for macroeconomic policy effects and a role for unexplained regional heterogeneity as well as some evidence of parameter heterogeneity in the aggregate production function we conclude that the ability of cross country growth regressions to adjudicate the relative importance of alternative growth theories is limited despite the vast amount of empirical research generated by new growth theories there is remarkably little consensus on which mechanisms are most salient in explaining cross country differences this article is designed to provide some evidence on this question by examining the robustness of empirical support for different growth the ories as determinants of both aggregate growth and its underlying components total factor productivity tfp growth and physical and human capital accumulation one reason for the lack of empirical consensus on growth determinants is that the main statistical tool in empirical studies cross country growth regressions provides very different answers depending on how the regression is specified which for this context typically amounts to the choice of control variables individual papers typically employ regressions that include modest subsets of the body of regressors that have been pro posed in the literature as a whole others employ a kitchen sink approach to evaluate the relative evidentiary support of competing growth theories in such an exercise a large number of variables are included in a regression and those variables that prove to be significant are then declared to be the important determinants of growth while the others are dismissed as unimportant rodrik et al 2002 sachs 2003

the deer hunter the unintended effects of hunting regulations abstract to control the deer population state game commissions regulate the types of deer that can be legally harvested these regulations however might have an unintended effect on hunting related accidents by changing the care hunters take when firing their rifles a moral hazard effect or changing the composition of hunters using detailed data on hunting accidents and regulations in pennsylvania counties from 1990 to 2005 we find compelling evidence that harvesting restrictions increase the care hunters take in a manner consistent with moral hazard thus these regulations have a positive safety externality

fickle consumers durable goods and business cycles abstract this paper develops a three sector dynamic general equilibrium model with the specific aim of evaluating the role of consumer durables in the generation and propagation of business cycles the model displays indeterminacy at commonly considered realistic parameter restrictions and basically constant returns to scale if calibrated at modest increasing returns to scale the sunspots driven model version produces a close match to moments of aggregate u s data journal of economic literatureclassification numbers e00 e32

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

pareto improving social security reform when financial markets are incomplete this paper studies an overlapping generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system leads to a pareto improvement when returns to capital and wages are imperfectly correlated a system that endows retired households with claims to labor income enhances the sharing of aggregate risk between generations our quantitative analysis shows that abstracting from the capital crowding out effect the introduction of social security represents a pareto improving reform even when the economy is dynamically efficient however the severity of the crowding out effect in general equilibrium tends to overturn these gains

an empirical analysis of hunting lease pricing and value of game in sweden game species generate considerable benefits to society in terms of hunting values tourism and maintenance of ecosystem balance this paper seeks to estimate hunting values for multiple hunted species by disentangling the role of wildlife harvesting opportunities from other factors that affect hunting lease prices we examine the determinants of hunting lease prices in sweden using both spatial and nonspatial econometric techniques our analysis confirms considerable hunting values for fallow deer and wild boar also the study reveals the presence of spatial spillovers in lease prices implying that landowners have little scope for exerting monopoly power on the hunting lease market

redistributive shocks and productivity shocks abstract a productivity innovation reduces labor share at impact making it countercyclical it subsequently produces a long lasting increase that peaks five years later at a level larger in absolute terms than the initial drop before slowly returning to average i e labor share overshoots we estimate a bivariate shock process to the production function that under competition in factor markets accounts for this overshooting we pose this process in an otherwise standard real business cycle economy and we find that the contribution of productivity innovations to the variance of hours is 1 of that in the standard rbc model

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

rough and lonely road to prosperity a reexamination of the sources of growth in africa using bayesian model averaging this paper takes a fresh look at africa s growth experience by using the bayesian model averaging bma methodology bma enables us to consider a large number of potential explanatory variables and sort out which of these variable can effectively explain africa s growth experience posterior coefficient estimates reveal that key engines of growth in africa are substantially different from those in the rest of the world more precisely it is shown that mining primary exports and initial primary education exerted differential effect on african growth these results are examined in relation to the existing literature copyright 2008 john wiley sons ltd

episodes of war and peace in an estimated open economy model we analyze the effects of world wars on the macroeconomic dynamics of the u s france germany and the uk by means of an estimated open economy model the model allows wars to affect the economy through capital depreciation sovereign default a military draft household preferences and spillovers on other exogenous processes productivity investment trade policy variables if the bulk of fluctuations during war episodes can be explained by the rise in government spending in the u s other factors are crucial in other countries we also discuss the size and state dependence of public spending multipliers and a counterfactual welfare exercise

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

tarnishing the golden and empire states land use restrictions and the u s economic slowdown abstract this paper studies the impact of state level land use restrictions on u s economic activity focusing on how these restrictions have depressed macroeconomic activity since 2000 we use a variety of state level data sources together with a general equilibrium spatial model of the united states to systematically construct a panel dataset of state level land use restrictions between 1950 and 2014 we show that these restrictions have generally tightened over time particularly in california and new york we use the model to analyze how these restrictions affect economic activity and the allocation of workers and capital across states counterfactual experiments show that deregulating existing urban land from 2014 regulation levels back to 1980 levels would have increased us gdp and productivity roughly to their current trend levels california new york and the mid atlantic region expand the most in these counterfactuals drawing population out of the south and the rustbelt general equilibrium effects particularly the reallocation of capital across states account for much of these gains

wars and capital destruction abstract in this paper we propose a theoretical framework to investigate the impact of conflicts and wars on key macroeconomic aggregates and welfare using a panel data with 9 countries from 1870 onwards we first show that the consumption to output ratio is minimal during wwii for participants while this can be explained by an increase in public spending in the usa this cannot be the case in other countries that participated in wwii as they experience a large fall in output during wartime to account for this we build a variation of a real business cycle model first proposed by hercowitz and sampson 1991 we extend the initial model to account for specific shocks that destroy private and public capital stocks as conflicts do by assuming an exogenously time varying parameter in the law of capital accumulation in addition the model imbeds generalized tfp shocks capturing standard technological factors as well as the potential effects of war on the labor force the model is estimated and used i to assess the importance of capital shocks during war episodes and ii to quantify the welfare effects of conflicts we show that capital shocks are crucial to account for the macroeconomic dynamics of countries that have experienced large war related destruction and that the welfare losses from fluctuations can be quite large when considering data samples that include major war episodes

asset pricing and the propagation of macroeconomic shocks this paper considers the implications of habit formation and financial frictions for the propagation of macroeconomic shocks in a model that is capable of matching asset pricing moments a short lived shock that destroys a small fraction of the economy s stock of pledgeable collateral generates a persistent recession a stock market crash and a flight to safety effect this novel mechanism creates a tight link between the asset pricing implications of macroeconomic models and their ability to propagate and amplify the effects of macroeconomic shocks

likelihood based estimation of dynamic panels with predetermined regressors this article discusses the likelihood based estimation of panel data models with individual specific effects and both lagged dependent variable regressors and additional predetermined explanatory variables the resulting new estimator labeled as subsystem limited information maximum likelihood ssliml is asymptotically equivalent to standard panel generalized method of moment as n for fixed t but tends to present smaller biases in finite samples as illustrated in simulation experiments simulation results also indicate that the estimator is preferred to other alternatives available in the literature in terms of finite sample performance finally to provide an empirical illustration i revisit the evidence on the relationship between income and democracy in a panel of countries using the proposed estimator

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

moose hunting values in sweden now and two decades ago the swedish hunters revisited this paper is based on two national contingent valuation studies dealing with the extent and economic values of hunting in sweden the first valuation study was conducted in 1987 and the second in 2006 both the game resource and the hunter community have undergone changes in the two decades covered by the surveys an important purpose of the latter survey was to repeat relevant parts of the former one which created a rare opportunity to compare valuations covering a very long time span moose hunting value and its determinants were compared between the two studies showing that significant changes have taken place our analysis suggests caution in using results from old contingent valuation studies for e g benefits transfer exercises

the aggregate effects of sectoral reallocations abstract can a one time permanent change in the fundamentals behind the sectoral composition of the economy prompt an aggregate downturn can this downturn be non negligible even if one uses us data to determine the relative size of gross vs net job flows and the importance of job creation costs can one consider the military build down of the 1990s as a plausible cause for the 1990 1991 recession do sectoral reallocations generate responses that are qualitatively similar to productivity shocks we use a variant of the mortensen pissarides 1994 review of economic studies 61 397 415 job creation destruction model calibrate it to us labor market data and run experiments that suggest one can answer yes to all these questions

propagation and smoothing of shocks in alternative social security systems abstract even with well developed capital markets there is no private market mechanism for trading between current and future generations this generates a potential role for public old age pension systems to spread economic and demographic shocks among different generations this paper evaluates how different systems smooth and propagate shocks to productivity fertility mortality and migration in a realistic olg model we use reductions in the variance of wealth equivalents to measure performance starting with the existing u s system as a unifying framework in which we vary how much taxes and benefits adjust and which we then compare to the existing german and swedish systems we find that system design and shock type are key factors the german system and the benefit adjustment only u s system best smooth productivity shocks which are by far the most important shocks overall the german system performs best while the swedish system which includes a buffer stock to relax annual budget constraints performs rather poorly focusing on the u s system reliance solely on tax adjustment fares best for mortality and migration shocks while equal reliance on tax and benefit adjustments is best for fertility shocks

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

can world real interest rates explain business cycles in a small open economy abstract while the world real interest rate is potentially an important mechanism for transmitting international shocks to small open economies much of the recent quantitative research that studies this mechanism concludes that it has little effect on output investment and net exports we re examine the importance of world real interest rate shocks using an approach that reverses the standard real business cycle methodology we begin with a small open economy business cycle model but rather than specifying the stochastic processes for the shocks and then solving and simulating the model to evaluate how well these shocks explain business cycles we use the model to back out the shocks that are consistent with the model s observable endogenous variables then we use variance decompositions to examine the importance of each shock we apply this methodology to canada and find that world real interest rate shocks can play an important role in explaining the cyclical variation in a small open economy in particular they can explain up to one third of the fluctuations in output and more than half of the fluctuations in net exports and net foreign assets

how democracy affects growth abstract this paper introduces a new methodology to examine the empirical relationship between democracy and economic growth democratic institutions are assumed to affect growth through a series of channels we specify and estimate a full system of equations determining growth and the channel variables results suggest that democracy fosters growth by improving the accumulation of human capital and less robustly by lowering income inequality on the other hand democracy hinders growth by reducing the rate of physical capital accumulation and less robustly by raising the ratio of government consumption to gdp once all of these indirect effects are accounted for the overall effect of democracy on economic growth is moderately negative our results indicate that democratic institutions are responsive to the demands of the poor by expanding access to education and lowering income inequality but do so at the expense of physical capital accumulation

losers and winners in economic growth this paper examines the growth rates in 116 economies from 1965 to 1985 it finds that the lowest quintile had an average growth rate of real gross domestic product gdp per capita of 1 3 percent whereas the highest quintile averaged 4 8 percent the authors isolate five influences that discriminate reasonably well between slow and fast growers a conditional convergence effect whereby a country grows faster if it begins with lower real gdp per capita in relation to its initial level of human capital in the forms of educational attainment and health a positive effect on growth from a high ratio of investment to gdp although this effect is weaker than that reported in some previous studies a negative effect from excessively large government a negative effect from government induced distortions of markets and a negative effect from political instability overall the fitted growth rates for eighty five economies for 1965 85 had a correlation of 0 8 with the actual values the authors also find that female educational attainment has a pronounced negative effect on fertility whereas female and male attainment are each positively related to life expectancy and negatively related to infant mortality

endogenous capital depreciation and technology shocks i examine the dynamic impact of capital maintenance on key aggregates through the depreciation rate i find that two factors are crucial for the short run effects of total factor productivity and investment specific shocks i the marginal efficiency of maintenance and its connection with the rate of utilization and ii the interplay between the intertemporal effect of maintenance and the substitution effect between maintenance and utilization the latter is expressed by the relative size of the elasticity of maintenance to the hicksian elasticity of complementarity between maintenance and utilization these theoretical results suggest that to match the observed responses of the macroeconomic aggregates the sign of the cross derivative should be negative and that the relative size of the hicksian elasticity should be smaller than the maintenance elasticity of marginal depreciation finally the model suggests that the main macroeconomic aggregates react procyclically with the exception of maintenance the behavior of which depends on the type of the shock

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

model averaging in economics an overview standard practice in empirical research is based on two steps first researchers select a model from the space of all possible models second they proceed as if the selected model had generated the data therefore uncertainty in the model selection step is typically ignored alternatively model averaging accounts for this model uncertainty in this paper i review the literature on model averaging with special emphasis on its applications to economics finally as an empirical illustration i consider model averaging to examine the deterrent effect of capital punishment across states in the usa

the cycle of earnings inequality evidence from spanish social security data we use detailed information on labor earnings and employment from social security records to document the evolution of male daily earnings inequality in spain from 1988 to 2010 we find that inequality was strongly countercyclical it increased around the 1993 recession experienced a substantial decrease during the 1997 2007 expansion and then a sharp increase during the recent recession this evolution went in parallel with the cyclicality of employment in the lower middle part of the wage distribution our findings highlight the importance of the housing boom and bust in this evolution suggesting that demand shocks in the construction sector had large effects on aggregate labor market outcomes

how much do distortions affect growth abstract this paper presents a simple endogenous growth model with two types of capital which can display sizeable long run growth effects of distortionary policies the model applies to many different types of distortions of relative prices common in developing countries such as differential taxes and tariffs black market exchange rates and price controls the model shows that a subsidy to one type of capital financed by a tax on another capital good lowers growth a measure of the variance of relative prices of investment goods across sectors has a negative and statistically significant effect on growth

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

growth empirics in panel data under model uncertainty and weak exogeneity this paper considers panel growth regressions in the presence of model uncertainty and reverse causality concerns for this purpose my econometric framework combines bayesian model averaging with a suitable likelihood function for dynamic panel models with weakly exogenous regressors and xed eects an application of this econometric methodology to a panel of countries over the 1960 2000 period highlights the diculties in identifying the sources of economic growth by means of cross country regressions in particular none of the nine candidate regressors considered can be labeled as a robust determinant of economic growth moreover the estimated rate of conditional convergence is indistinguishable from zero

parameter drifts misspecification and the real exchange rate in emerging countries abstract this paper reviews the baseline framework for the analysis of emerging economies using argentinean data i estimate a small open economy model with stochastic trend working capital constraint and augmented with time varying parameters i find that structural technological and financial parameters of one sector model are time varying during 1936 2006 time varying parameters correlate with the real exchange rate suggesting potential misspecification of the one sector model therefore i propose a two sector model that endogenously accounts for the real exchange rate in this model stationary productivity shocks and the country premium together explain a large share of the variability observed in the data

is god in the details a reexamination of the role of religion in economic growth summary barro and mccleary 2003 religion and economic growth across countries american journal of sociology 68 760 781 is a key research contribution in the new literature exploring the macroeconomic effects of religious beliefs this paper represents an effort to evaluate the strength of their claims we evaluate their results in terms of replicability and robustness overall their analysis generally meets the standard of statistical replicability though not perfectly on the other hand we do not find that their results are robust to changes in their baseline statistical specification when model averaging methods are employed to integrate information across alternative statistical specifications little evidence survives that religious variables help to predict cross country income differences copyright 2011 john wiley sons ltd

using theory for measurement an analysis of the cyclical behavior of home production abstract a significant amount of economic activity takes place within the home unfortunately it is difficult to assess the cyclical properties of home production because the available data are too sporadic using a real business cycle rbc model we construct quarterly data on three variables that are unobservable at a quarterly frequency hours worked in the home sector hours spent in leisure and the consumption of home produced goods three results emerge leisure is countercyclical while nonmarket hours are acyclical hours spent in home production have declined significantly since the 1970s fluctuations in market output are a good measure of fluctuations in individual utility as long as home and market consumption are either extreme complements or extreme substitutes in the production of utility

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

technical progress and aggregate fluctuations abstract we compare the cyclical fluctuations exhibited by a stochastic growth model under various stochastic processes governing technical change all of which are highly autocorrelated the results obtained are quite sensitive to the precise form of this stochastic process in particular the results depend on whether growth is deterministic or stochastic and in each case are quite sensitive to the persistence of an innovation the model does a relatively poor job of accounting for features of observed business cycles when technical change is difference stationary and does a better job when technical change is trend stationary but highly autocorrelated
