intervention policy of the boj a unified approach intervening in the fx market implies a complex decision process for central banks monetary authorities have to decide whether to intervene or not and if so when and how since the successive steps of this procedure are likely to be highly interdependent we adopt a nested logit approach to capture their relationships and to characterize the prominent features of the various steps of the intervention decision process our estimations based on japanese data from 1991 to 2004 indicate that the bank of japan i mainly reacted to deviations of the exchange rate with respect to fundamentals and ii tended to favour secrecy when its credibility was low we also provide new insights on the so called secrecy puzzle by modeling explicitly the risk for a secret intervention to be detected our results have important implications in terms of exchange rate policy such as the emergence of a trade off between intervention size communication policy and secrecy our results tend to provide some explanation for the observed persistence of ineffective intervention policy during some sub periods c 2008 elsevier b v all rights reserved

factor productivity and income inequality a general equilibrium analysis economic growth over the past two decades has failed to reduce income inequality we contend that major reasons for this are the slowdown and bias in technological change productivity growth given the complexity of the many interactions that take place this phenomenon is best addressed in a general equilibrium context for this purpose we have developed a computable general equilibrium cge model with advanced features relating to income distribution we perform a series of simulations based on recent overall productivity changes but under various forms of technological change bias factor mobility and government budgetary balance we find the labour augmenting technological change cases to be most consistent with recent experience

foreign exchange market intervention and expectations the yen dollar exchange rate abstract using press reports and official statistics on central bank intervention in conjunction with options market data we find that central bank intervention had no statistically significant systematic impact on the mean or higher moments of the exchange rate during 1993 2000 we also find that japanese authorities appeared to intervene mainly in response to deviations of the exchange rate from some implicit target levels and to a rise in market uncertainty u s monetary authorities intervened only in cooperation with the japanese authorities

aggregate fluctuations with national and international returns to scale cyclical movements in aggregate output factor inputs and productivity are all positively correlated across countries this article proposes a model in which positive cross country correlations of these variables result from increasing returns to the world wide variety of intermediate goods even if technology shocks are purely country specific the model also accounts for the observed positive relationship between bilateral trade volume and international comovements positive comovements can also arise with constant returns to variety but only if technology shocks are themselves strongly correlated the combination of constant returns and common shocks however tends to generate procyclical fluctuations of the trade balance

estimation of scale economies underlying growth and productivity the empirical implications of data aggregation estimation of scale economies underlying growth and productivity patterns is typically based on aggregated data raising questions about the potential for aggregation biases this paper provides empirical evidence on the existence and patterns of such biases we use a cost based model to estimate short long run and internal external scale effects for u s manufacturing data at different aggregation levels our results suggest that aggregation biases in such a model are not substantive also internal scale economies seem more appropriately represented by the aggregate data whereas more disaggregated data appears preferable for estimation of external or spillover effects that occur between industries or sectors

long run welfare under externalities in consumption leisure and production a case for happy degrowth vs unhappy growth in this paper we contribute to the debate on the relationship between growth and well being by examining an endogenous growth model where we allow for externalities in consumption leisure and production we analyze three regimes a decentralized economy where each household makes isolated choices without considering their external effects a planned economy where a myopic planner fails to recognize both leisure and consumption externalities but recognizes production externalities and a planned economy with a fully informed planner we first compare the balanced growth paths under the three regimes and then we numerically investigate the transition to the optimal balanced growth path we provide a number of findings first in a decentralized economy growth or labor or both are greater than in the regime with a fully informed planner and hence are sub optimal from a welfare standpoint second a myopic intervention which overlooks consumption and leisure externalities leads to more growth and labor than in both the decentralized and the fully informed regime third we provide a case for happy degrowth a transition to the optimal balanced growth path that is associated with downscaling of production a reduction in private consumption and an ongoing increase in leisure and well being

procyclical labor productivity and competing theories of the business cycle some evidence from interwar u s manufacturing industries we study the phenomenon of short run increasing returns to labor srirl in a sample of 10 interwar u s manufacturing industries our main findings are that srirl was common in the interwar period and that the pattern of srirl across industries was similar to that observed in the postwar period we argue that since presumably the depression was not caused by technical regress these findings are inconsistent with the claim of real business cycle theorists that srirl is in general due to procyclical technical shocks we propose tests for discriminating between two other leading explanations of srirl but find that our conclusions differ by industry

total factor productivity and the measurement of technological change tfp is interpreted in the literature in different mutually contradictory ways changes in tfp are shown to measure not technological change only the super normal returns to investing in such change returns that exceed the full opportunity cost of the activity thus in the limit technological change can proceed with unchanged tfp measuring the effects of technological change instead requires counterfactual estimates reasons why changes in tfp are imperfect measures of super normal returns are also studied reasons connected with the timing of output responses the treatment of r d in the national accounts the omission of resource inputs and two types of aggregation la productivite totale des facteurs et la mesure du changement technologique la productivite totale des facteurs ptf est interpretee dans la litterature de manieres differentes et mutuellement contradictoires on montre que les changements dans la ptf ne mesurent pas le changement technologique mais seulement les rendements supra normaux sur les investissements dans de tels changements des rendements qui depassent le plein cout d opportunite de cette activite donc a la limite le changement technologique peut proceder sans que la ptf change mesurer les effets du changement technique reclame des evaluations d hypotheses de rechange les raisons pour lesquelles les changements dans la ptf sont des mesures imparfaites des rendements supra normaux sont aussi etudiees raisons connectees avec la reponse des niveaux de production le traitement de la r d dans les comptes nationaux l omission des intrants de ressources et deux types d agregation

target zones and exchange rate dynamics this paper develops a simple model of exchange rate behavior under a target zone regime it shows that the expectation that monetary policy will be adjusted to limit exchange rate variation affects exchange rate behavior even when the exchange rate lies inside the zone and is thus not being defended actively somewhat surprisingly the analysis of target zones turns out to have a strong formal similarity to problems in option pricing and investment under uncertainty

migration regional equilibrium and the estimation of compensating differentials in this study we have developed an improved model of net migration that encompasses both equilibrium and disequilibrium components instrumental variables fixed effects estimates of the model with time series data for 51 areas in the united states over the period 1971 1988 support the importance of both equilibrium and disequilibrium factors in migration excerpt

multiple equilibria coordination and transitional growth abstract we study a small open economy with two sectors and two factors of production in one of the sectors external economies of scale are generated through the industry level capital input this leads to a divergence between private and social production possibility frontiers as well as to multiple equilibria the equilibrium selection problem that arises is solved by agents who follow a simple trial and error learning rule the growth path of the economy as agents learn lies below the production possibility frontier and may display cyclical transitional dynamics we also show that coordination problems which may prevent the economy from attaining the good equilibrium may be alleviated by the temporary use of policy instruments that shape the allocation of resources

jobs versus amenities in the analysis of metropolitan migration abstract this paper demonstrates that jobs and wages are considerably more important than location specific amenities in explaining net metropolitan migration of employed persons these results which are derived mainly from a unique set of annual migration data differ considerably from the earlier findings of p e graves j urban econom 6 135 147 1979 that show amenities to be powerful contributors to the analysis of net metropolitan migration several hypotheses are offered and tested to explain the appreciable difference between graves s results and those of the present study but the importance of economic factors as opposed to amenities persists the findings of this study are generally consistent with the earlier findings of muth southern econom j 37 295 306 1971

a cobweb model with local externalities abstract this paper considers an extension of the standard cobweb model in a market with local externalities in contrast with the standard cobweb model firms must forecast both prices and local quantities we develop new constructive stability and existence conditions for equilibria with positive outputs we find evidence of clusters of firms whose output behavior is correlated as equilibrium is reached we also show that an appropriately defined representative agent model with a global externality exhibits the same mean or second order properties of aggregate output as the more complex model with local externalities

information acquisition in global games of regime change abstract we study costly information acquisition in global games of regime change that is coordination games where payoffs are discontinuous in the unobserved state and in the agents average action we show that only symmetric equilibria exist and provide sufficient conditions for uniqueness we then characterize the value of information in these games and link it to the underlying parameters of the model we investigate equilibrium efficiency complementarities in information choices and the trade offs between public and private information we show that information acquisition can be inefficient and that strategic complementarities in actions do not always translate into strategic complementarities in information acquisition finally we find that public and private information can be complements these results contrast findings in linear quadratic models where payoffs depend continuously on both the unobserved state and the agents average action

public conservation land and employment growth in the northern forest region we quantify the effect that public conservation lands have on employment growth in the northern forest region of the united states a model of simultaneous employment and net migration growth is estimated with data on non metropolitan counties from 1990 to 1997 exogenous variables include the 1990 share of the land base in public conservation uses we find that net migration rates were higher in counties with more conservation lands but the effects are relatively small no significant effect on employment growth is detected as well variables measuring changes in public timber harvests have no effect on employment growth

seasonal solow residuals and christmas a case for labor hoarding and increasing returns in aggregate unadjusted data measured solow residuals exhibit large seasonal variations total factor productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of 24 percent how much of the total seasonal variation in the measured solow residual can be explained by christmas the answer to this question is surprising with increasing returns and time varying labor effort christmas is sufficient to explain the seasonal variation in the solow residual consumption average productivity and output in all four quarters our analysis of seasonally unadjusted data uncovers important roles for labor hoarding and increasing returns that are difficult to identify in adjusted data prescott 1986 has argued that the variability of solow s residual is a reasonable estimate of the variability of exogenous technology shocks when solow s residual is measured using seasonally unadjusted data for the postwar u s economy it exhibits large seasonal variations growing rapidly in the fourth quarter at an annual rate of 16 percent and falling sharply in the first quarter at an annual rate of 24 percent this paper starts from the premise that it is implausible to attribute seasonal variation of this magnitude to changes in the state of technology we present a model in which all seasonal fluctuations arise from a single demand shift christmas this demand shift together with misspecification of the traditional production function leads to large seasonal variation in the solow residual we consider two candidates for misspecification labor hoarding and external increasing returns to scale even when technological growth is aseasonal either candidate in isolation can induce spurious seasonality in the solow residual our general equilibrium analysis indicates that 1 the economy s seasonal patterns in all four quarters may be a response simply to a fourth quarter consumption demand shift and 2 a combination of labor hoarding and external increasing returns is important for replicating these patterns in aggregate quantity variables for the postwar u s economy since our analysis identifies important roles for labor hoarding and increasing returns these results have implications for nonseasonal macroeconomic models indeed our analysis im

interpreting the procyclical productivity of manufacturing sectors can we really rule out external effects recent empirical contributions on procyclical productivity have focused on the dynamic implications of persistent aggregate fluctuations on sectoral productivity given a permanent innovation in aggregate output unobserved variations of labour or capital utilization may have only a transitory effect on measured productivity whereas external effects should produce permanent effects it is found that persistent aggregate fluctuations have a permanent effect on productivity of four digit us manufacturing industries while a number of alternative explanations of this evidence are discussed and ruled out the findings are consistent with a simple model with external or thick market effects

measuring business cycles a modern perspective in the first half of this century special attention was given to two features of the business cycle 1 the comovement of many individual economic series and 2 the different behavior of the economy during expansions and contractions both of these attributes were ignored in many subsequent business cycle models which were often linear representations of a single macroeconomic aggregate however recent theoretical and empirical research has revived interest in each attribute separately notably dynamic factor models have been used to obtain a single common factor from a set of macroeconomic variables and nonlinear models have been used to describe the regime switching nature of aggregate output we survey these two strands of research and then provide some suggestive empirical analysis in an effort to unite the two literatures and to assess their usefulness in a statistical characterization of business cycle dynamics

identifying the efficacy of central bank interventions evidence from australia and japan abstract using a model incorporating the endogenous relationship between exchange rates and intervention we show how a change in central bank policy can be used as an identification assumption estimating this model with simulated gmm for daily data from australia and japan we find that a us 100 million purchase appreciates the australian dollar by 1 3 1 8 but the yen by just 0 2 almost all of the impact of an intervention occurs during the day it is conducted and we confirm that central banks typically lean against the wind

cyclical productivity in europe and the united states evaluating the evidence on returns to scale and input utilization this paper studies procyclical productivity growth at the industry level in the united states and three european countries france germany and the netherlands industry specific demand side instruments are used to examine the prevalence of non constant returns to scale and unmeasured input utilization for the aggregate us economy unmeasured input utilization seems to explain procyclical productivity however this correction still leaves one in three us industries with procyclical productivity this failure of the model can also be seen in europe and is mostly concentrated in services industries

dynamic complementarities a quantitative analysis abstract this paper considers the importance of dynamic complementarities as an endogenous source of propagation in a dynamic stochastic economy dynamic complementarities link the stocks of human and organizational capital which are influenced by past levels of economic activity to current levels of productivity we supplement an otherwise standard dynamic business cycle model with both contemporaneous and dynamic complementarities the model is calibrated using estimates of these effects from both micro and aggregate data our quantitative analysis identifies empirically relevant dynamic complementarities as a source of propagation for both technology and taste shocks

monopolistic competition increasing returns to scale and the welfare costs of inflation abstract this paper introduces monopolistic competition and increasing returns to scale into a monetary real business cycle rbc model to re estimate the welfare costs of inflation we first calibrate the model and show that it is capable of generating the observed aggregate fluctuations even when there are no shocks to the fundamentals in particular we demonstrate that this model matches the stylized u s business cycles facts as well as two more standard models then we find that in this model the scale parameters and the intensity of competition significantly affects the welfare cost of inflation specifically the cost is considerably higher than that in a standard rbc model with competitive markets and constant returns moreover the stronger the increasing returns and the less intense the competition the higher the welfare costs these results are confirmed in a number of model specifications

trust on the brink of armageddon the first strike game abstract we introduce the experimental first strike game two players accumulate earnings over many rounds in any round a player can deactivate the opponent this means that the opponent loses all earnings and faces severely reduced future payoffs it also means that the opponent can no longer deactivate the aggressor in later rounds thus deactivation is a hostile act but can serve as a self protection device we run four treatments to disentangle the effect of spite fear of spite and trust we find the absence of pure nastiness but nevertheless a strong fear of it mutual trust can considerably reduce hostility

central city crime and suburban economic growth this paper explores the relationship between inner city crime patterns and suburban income growth analysing data on 318 us counties for selected metropolitan statistical areas of 32 states within the united states from 1982 to 1997 the findings suggest that violent crime does seem to have a negative impact on close in suburbs with a less negative impact farther away from the central city becoming positive at some point while results are not as robust as we had hoped they are consistent with flight to further out suburbs rather than migration to different metropolitan areas in response to urban crime

what prompts japan to intervene in the forex market a new approach to a reaction function abstract this paper estimates and analyzes the reaction function of japanese intervention in the foreign exchange forex markets using daily japanese intervention data from april 1 1991 to december 31 2002 a theoretical friction model is adopted to describe the intervention as cost minimizing behavior an ordered probit model consistent with the theoretical model is employed to estimate authorities reaction function a noise to signal ratio is applied in selecting the optimal cutoff point in estimated ordered probit function major findings are as follows 1 a regime change in june 1995 from small scale frequent interventions to large scale infrequent interventions is detected 2 the optimum cutoff is higher in the first half than the second half

free entry and business cycles under the influence of animal spirits abstract we provide a business cycle model in which endogenous markup fluctuations are the main driving force these fluctuations occur due to some form of animal spirits impelling firms in their entry exit decisions within each sector by contrast to existing models of the business cycle emphasizing the role of animal spirits we do not rely on the sink property of the equilibrium to generate indeterminacy hence while our model does pretty well in accounting for the main features of us business cycles it avoids several criticisms addressed to these former models concerning either their dependence upon strongly increasing returns too high markups or their implication of countercyclical movements of consumption

external effects in u s procyclical productivity abstract in this paper we highlight a new dimension of the aggregate procyclical productivity phenomenon we show that estimates of the degree of returns to scale are larger for manufacturing as a whole than for two digit industries since this difference must be due to factors that are only internalized at the most aggregate level we term it an external effect this result rules out explanations based on own input variation such as true increasing returns and unmeasured factor utilization tied to own activity as the sole explanations for aggregate procyclical productivity we explore several potential explanations of this external effect

quasi fixed inputs in u s and japanese manufacturing a generalized leontief restricted cost function approach in this paper a generalized leontief variable cost function is develope d which permits analytical derivation of steady state levels of quasi fixed inputs and capacity output and does not require specification of a numeraire input this framework is then used to evaluate the fa ctor demand patterns of japanese and u s manufacturing based on bot h one quasi fixed capital input and two quasi fixed capital and la bor input specifications and both static and dynamic optimization t he findings provide evidence of considerable flexibility of demand re sponses in japan which may have contributed to japan s relatively st rong economic performance in the volatile 1970s copyright 1988 by mit press

real business cycles and sunspot fluctuations are observationally equivalent abstract this paper points out that real business cycle models are observationally equivalent to externality models which we define as models with externalities and sunspots but without productivity shocks as far as standard first order systems are concerned however externality models turn out to be more flexible than rbc models this explains at least partly why previous studies have found that externality models perform better than standard rbc models at generating realistic business cycle behavior our results cast doubt on the arguments of farmer and guo 1994 and caballero and lyons 1992

endogenous business cycles and the dynamics of output hours and consumption abstract this paper studies the business cycle fluctuations predicted by a two sector endogenous business cycle model with sector specific external increasing returns to scale it focuses on aspects of actual fluctuations that have been identified both as defining features of business cycles and as ones standard real business cycle models cannot explain for empirically realistic calibrations of the degree of returns to scale the results suggest that endogenous fluctuations do not provide the dynamic element that is missing in existing real business cycle models jel e32

increasing returns and externalities in uk manufacturing myth or reality i apply the method of caballero and lyons to industry level data for uk manufacturing i find evidence for a positive external effect arising from the expansion of manufacturing as a whole but expansion at the sectoral level was found not to generate external effects nor was any evidence found for increasing returns which are internal to the industry here returns appear to be constant i argue that external effects at the level of aggregate manufacturing cannot be explained away as due to measurement error or cyclical effects however alternative explanations such as economy wide shocks cannot be totally excluded

how many winners are good to have on tournaments with sabotage abstract from an employer s perspective a tournament should induce agents to exert productive activities but refrain from destructive ones we experimentally test the predictive power of a tournament model which suggests that within a reasonable framework productive and destructive activities are influenced neither by the number of agents taking part in the tournament nor by the fraction of the winner prizes our results clearly confirm that sabotage in tournaments indeed occurs while tournament size has virtually no effect on behavior a balanced fraction of winner and loser prizes appears to enhance productive activities

on the effectiveness of private and public capital this study assesses the effectiveness of private and public capital investments in the performance of manufactures within the framework of the duality theory the response of costs of production and input utilization to changes in the stocks of private and public capital is measured by the appropriate elasticities obtained from a cost function instead of considering private capital either as a variable or fixed input on a priori grounds its nature is checked that is the study discriminates between a long and a short run situation the empirical exercise is made for the manufacturing industries in the spanish regions

endogenous business cycle propagation and the persistence problem the role of labor market frictions contrasting sharply with a recent trend in dsge modeling we propose a business cycle model where frictions and shocks are chosen with parsimony the model emphasizes a few labor market frictions and shocks to monetary policy and technology the model estimated from u s quarterly postwar data accounts well for important differences in the serial correlation of the growth rates of aggregate quantities the size of aggregate fluctuations and key comovements including the correlation between hours and labor productivity despite its simplicity the model offers an answer to the persistence problem chari et al 2000 that does not rely on multiple frictions and adjustment lags or ad hoc backward looking components we conclude modern dsge models need not embed large batteries of frictions and shocks to account for the salient features of postwar business cycles

migration and the dynamic stability of regional econometric models two different versions of a representative model of population employment and induced spending are introduced and discussed the second version is then fitted to time series data for alaska arizona colorado and florida and tested for sensitivity to slight variations in the parameters of the net migration equation all four fitted models are found to be dynamically unstable the implications concerning the equation are considered annotation

sources of productivity growth an empirical analysis with german sectoral data many theoretical analyses of the sources of economic growth focus on knowledge spillovers and scale economies to explain growth endogenously the contribution of this paper is to shed some light on these arguments by an empirical investigation based on a production function framework sectoral production functions are estimated with annual german data of 51 sectors from 1960 90 the estimates reveal that both a pure solow growth model and a solow model augmented with human capital cannot account for the observed productivity increases the model should be extended by allowing for inter industry spillovers and scale economies at the aggregate level as well as for scale economies associated with human capital at the sectoral level the business cycle affects observed productivity changes in the short run and in the long run

inflexible prices and procyclical productivity hall has shown that with perfect competition and price flexibility total factor productivity measured using labor s share either in revenues or in costs will be acyclical regardless of the level of labor hoarding we show that if firms producing a homogeneous good under constant returns must pick their prices before demand is known both measures of productivity become procyclical the model implies that productivity should be more procyclical the more important is labor hoarding empirically productivity is more procyclical in industries and in nations where labor hoarding appears more important

scale effects time varying markups and the cyclical behaviour of primal and dual productivity this paper presents estimates of the degree of returns to scale using nonparametric measures of primal and dual productivity for 2 digit us manufacturing industries as part of the analysis the cyclical behaviour of primal and dual productivity measures are considered time varying markups are allowed for and the small sample properties of the instrumental variables estimator used to derive the estimates from the primal and dual relations examined both the primal and dual estimates indicate the existence of increasing returns to scale for the durable goods industries the simulation results indicate there is a slight tendency for the dual equation estimates to overestimate the degree of returns to scale however small sample bias appears to be most severe for the non durable goods industries

nonconvex costs and the behavior of inventories this paper explores one possible explanation for the apparent excess volatility of production relative to sales nonconvexities in the technology facing firms it is shown that if firms operate in a region of declining marginal costs then small shifts in demand can cause production to jump substantially estimates for six production to stock industries as well as the automobile industry suggest that all these industries behave as if they were operating in the region of nonconvex costs the results have important implications not only for inventory investment but also for the cyclical behavior of productivity and prices

growth welfare and the size of government i introduction given the current state of political debate within the u s it would appear that making the claim a smaller government is a better government is just a mere statement of a simple fact president clinton the head of the political party which has traditionally supported a larger government has now proclaimed that the era of big government is over and has proposed fiscal programs to cut both taxes and the growth of government spending in a very real sense it has been economists who have been consensus makers on this issue numerous studies have been conducted recently estimating the growth and welfare costs of distortionary taxation 1 these studies have generally found that income and capital taxation have large welfare effects and also significant effects on growth however the potential benefits of the government purchases financed with distortionary taxes are very limited in these supply side models most often being simply ignored in these aforementioned studies government purchases do not directly provide utility to households and do not affect the productivity of firms as a result the optimal size of government in these models is zero which is a troubling property of any model being used to evaluate the effects of changes in fiscal policy in terms of cost benefit analysis by ignoring these effects previous studies have only considered the costs of a larger government but not the benefits 2 this paper develops an endogenous growth model of the u s economy in which government purchases directly affect both the utility of individuals through the provision of public consumption goods and services and the productivity of firms through the provision of public capital in a manner which is consistent with existing empirical work by aschauer 1985 1989 and munnell 1990a b among others by incorporating the full benefits of government purchases into our model the growth and welfare effects of a smaller government can be more realistically evaluated this paper proceeds as follows in section ii the endogenous growth model with human capital accumulation used in this study is described the competitive equilibrium of the model is described and calculated in section iii and the calibration of the parameters in the model is discussed in section iv in section v various fiscal policy experiments are conducted investigating the growth and welfare effects of government downsizing although this is a macroeconomic model and as such is too general to investigate the effects of specific government spending and taxation programs the results presented here do provide some broad fiscal policy guidelines 1 the effects of a smaller government depend as much on the mix of spending cuts as on the mix of tax cuts and government downsizing is not necessarily growth and welfare enhancing 2 while tax reductions by themselves can significantly increase growth and welfare simultaneous reductions in government spending and taxation are not likely to lead to large positive or negative changes in growth or welfare regardless of the exact form of the spending and tax cuts 3 reducing the size of government is less likely to increase growth and welfare if the reductions in public investment are large especially reductions in public investment which directly affect the accumulation of human capital 4 government downsizing is most likely to increase growth and welfare if the proceeds from spending cuts are used to finance reductions in capital tax rates 5 across the board spending cuts fail to maximize the potential growth and welfare benefits of government downsizing although downsizing is more likely to increase growth and welfare if the cuts pertain to all forms of government spending including transfer payments and not just government purchases ii description of the model the model developed here is similar to the well known two sector endogenous growth model used by rebelo 1991 and king and rebelo 1990 with endogenous labor supply

externalities and growth accounting this paper tackles two puzzles the high empirical elasticity of aggregte output with respect to the measured capital input and the seemingly high variability of growth rates over countries in the medium run we find that one need not invoke increasing returns or externalities to capital to explain these two puzzles rather they are consistent with a constant returns to scale aggregate production function so long as the exogenous solow residual process has enough persistence in it in our model causality runs exclusively from knowledge to capital and therefore the apparent absence of an external effect to the capital input says nothing about the importance of spillovers in the creation of knowledge copyright 1991 by american economic association

internal versus external economies in european countries in this paper sectoral production functions are estimated with a two digit disaggregation for eight european countries corresponding to the period 1978 1992 distinguishing between internal economies of scale and intersectoral external effects in order to avoid the possibility that the regressions carried out by way of panel data techniques are spurious the integration order of each variable has been identified using unit root similarly the hausman procedure has been applied to test the exogeneity of the variables and determine whether the most appropriate estimations should be sur or three stage least squares

aggregate spillovers magnify the welfare benefits of tax reform relatively small degrees of aggregate increasing returns to scale substantially mag nify both welfare benefits and income effects associated with tax reform external returns to scale of 10 per cent increase the welfare benefits of tax reform by roughly one third and increase changes in income by significantly more than a model characterized by constant returns to scale aggregate spillovers of 20 per cent increase welfare benefits by roughly three fourths aggregate spillovers significantly reduce tax revenue maximizing capital tax rates this research convincingly demonstrates the importance of precisely identifying the degree of aggregate returns to scale before the benefits of tax reform can be accurately

spite and preemptive retaliation after tournaments abstract we investigated money burning after tournaments first we show that substantial money burning was triggered if participants perceived a situation as competitive second we investigated to which extent aggression between former contestants was motivated by preemptive retaliation or spite to disentangle both motives we introduced a credible and visible self binding signal contrary to previous studies we found that aggression against a defenceless subject played an important role preemptive retaliation proved to be another dominant motive we conclude that voluntary self binding signals may have the potential to mitigate but not eliminate antisocial behavior after a competition because it seems to be driven by spite to a large extent our results help us to better understand and eventually mitigate destructive behavior in work environments

procyclical labour productivity a closer look at a stylized fact at 4 digit united states manufacturing industry level we find evidence suggesting that the stylized fact of procyclical labour productivity should be treated with great caution we use the nber manufacturing productivity database to investigate the relationship between hourly labour productivity and real output for 450 industries for the years 1958 91 labour productivity is significantly procyclical in 63 of industries and acyclical in 36 in the latter respect a high proportion of investment goods industries display acyclical productivity cross section regressions are carried out that seek to explain the interindustry distribution of cyclicality the analysis attributes a significant role to variations in materials costs as a proxy for fluctuations in factor utilization

asymmetric herding as a source of asymmetric return volatility abstract as a considerable source of asymmetry in return volatility this paper introduces asymmetric herding and extends the continuous beliefs system to account for its asymmetry and derive the asymmetric herding parameters that are easily estimated by using a maximum likelihood method based on the garch type econometric model this paper presents new empirical evidence for asymmetry in the exchange rates volatility of major currencies against the us dollar which have bilateral nature interestingly the asymmetry of japanese yen is the opposite of that of others and the global financial crisis highlights the opposite asymmetry some of traditional hypotheses such as the leverage effect and the volatility feedback effect do not adequately explain these findings however a significant asymmetric herding effect is observed and appears to be time varying further the clear link between asymmetric herding and volatility strongly supports the hypothesis of the asymmetric herding effect

indeterminacy home production and the business cycle a calibrated analysis abstract in this paper i present a business cycle model with one market sector that produces a standard good and another that produces a non market or home good the model can have multiple equilibria and therefore cycles driven only by self fulfilling expectations with low externalities to market production in particular an upward sloping aggregate labor demand as e g in farmer and guo j economic theory 63 1994 42 72 is not required for indeterminacy the effect of technology shocks is also studied in all cases the time series that are generated have properties that are comparable to the real us postwar series

residential amenities firm location and economic development amenities are regarded as increasingly important to the location decisions of certain types of firm yet they are often ignored in economic development research because of the assumption that they attract only workers and that this workforce in turn attracts firms this paper argues for a reduced form model of the impact of amenities on corporate location when testing such a model at the intra metropolitan scale it will be necessary to measure amenities not only at the potential worksite but also where employees are likely to live this paper tests such a firm location model using a sample of municipalities in northern new jersey results support the hypothesis that firms evaluate certain amenities with respect to the likely residential locations of their employees

how does the border affect productivity evidence from american and canadian manufacturing industries abstract this study reports on how much productivity fluctuations are industry specific versus country specific for the manufacturing industries in canada and the united states the correlation between cross border pairings of the same industry are found to be more often highly correlated than previously thought furthermore the study confirms earlier findings that the similarity of input use can help describe the comovement of productivity fluctuations across industries

productivity technology and economic growth what is the relationship the relationship between productivity technology and economic growth has been debated extensively in the endogenous growth growth accounting new economy and policy literature this paper briefly surveys the literature on total factor productivity tfp calculations the various techniques and problems associated with it we argue that tfp is not a measure of technological change and only under ideal conditions does it measure the supernormal profits associated with technological change the critical driving force of economic growth is not the super normal profits that technological change generates but rather the continuous creation of opportunities for further technological development six illustrations of when tfp fails to correctly measure these super normal profits are provided a version carlaw and lipsey s 2003b model of endogenous general purpose technology driven growth is then utilized to make some progress toward answering prescott s 1998 call for a theory of tfp the model is used to simulate artificial data and connect theoretical assumptions of returns to scale and resource costs to the conditions under which tfp miss measures the actual growth of technological knowledge

identification long run relations and fundamental innovations in a simple cointegrated system this paper examines the roles played by innovations identified from a simple four variable var characterized by cointegration using knowledge of cointegration rank and textbook relations that link macroeconomic aggregates we identify distinct real and nominal innovations that dictate the long run behavior of the model we also examine the explanatory power of transitory innovations that are orthogonal to these permanent shocks one of the permanent shocks displays all the characteristics of a technology or supply innovation while one of the transitory innovations identified by imposing short run price rigid ity is interpretable as a demand side impulse the permanent nominal shock bears the imprint of an innovation in aggregate inflation expectations historical decomposition and comparison with variables that are external to the model reveals the relative importance of the shocks at various episodes

a mixed industrial structure magnifies the importance of menu costs new keynesian literature assumes symmetric industrial structure when analysing explanations of money non neutrality this paper analyses the impact of modifying this assumption by allowing for a mixed industrial structure some industries are characterized by monopolistic competition others by perfect competition the mixed industrial structure implies misallocation of labour between the different industries which may contribute to explanations of non neutrality of money following a 5 money increase the menu costs needed for non neutrality may be 40 times smaller and ratio of welfare gain over private loss more than 100 times larger than in the corresponding model with a symmetric structure

a new approach to the effect of intervention frequency on the foreign exchange market evidence from japan this article estimates and analyses the effect of intervention frequency on the yen dollar market using daily intervention data we examine using a nonlinear methodology with the frequency of intervention from april 1991 to december 2005 as a focal explanatory variable in this article we also introduce a flexible target zone model that is capable of characterizing the dynamic behaviour of an exchange rate implied by the original target zone model of krugman and its modifications the empirical results show the importance of considering the threshold effect when analysing the effect of intervention due to the presence of asymmetry in the foreign exchange market moreover we show that a high frequency intervention stabilizes the exchange rate by reducing exchange rate volatility especially when the yen appreciates

inventories employment and hours abstract this paper develops a model that integrates inventory and labor decisions we extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process distinguishing between employment hours and effort per worker we estimate jointly the euler equations for inventories and employment a labor compensation schedule and an hours requirement function with the cross equation restrictions imposed the econometric results shed light on several important topics including the shape of the marginal cost of output the role of labor hoarding as an explanation of pro cyclical productivity and the persistence of inventory stocks

central bank intervention and exchange rate volatility abstract this paper explores the effects of foreign exchange intervention by central banks on the behavior of exchange rates the g 3 central banks have undertaken an unprecedented number of both coordinated and unilateral intervention operations in the last 10 years existing empirical evidence on the effectiveness of intervention is mixed studies using data from the 1970s suggest that intervention operations that do not affect the monetary base have at most a short lived influence on exchange rates but more recent studies indicate that the intervention operations that followed the plaza agreement influenced both the level and variance of exchange rates this paper examines the effects of us german and japanese monetary and intervention policies on dollar mark and dollar yen exchange rate volatility over the 1977 1994 period the results indicate that intervention operations generally increase exchange rate volatility this is particularly true of secret interventions which are those undertaken by central banks without notification of the public overt interventions in the mid 1980s appear to have reduced exchange rate volatility but in other periods and for the 1977 1994 period as a whole central bank intervention is associated with greater exchange rate volatility

rational expectations business cycles in search equilibrium we examine the rational expectations equilibrium paths of the model of search and barter in diamond s aggregate demand management in search equilibrium for some initial positions there are two equilibrium paths converging to different steady states with the high activity path pareto dominating the low activity path with some parameters there is also a continuum of equilibrium paths converging to another steady state moreover there can be cycles that are equilibrium paths even though the environment is stationary

understanding gross worker flows across u s states abstract the main cross sectional and time series properties of state level gross and net worker flows wages and rents are characterized using micro data from the u s census a dynamic general equilibrium model of worker migration is introduced to explain the stylized facts in the model a location may experience simultaneous inflows and outflows of workers recent migrants choose to migrate more often than incumbent workers thus locations that attract high numbers of migrants also tend to experience high outflow rates this pattern is a robust feature of the data and cannot be explained by models of net flows only

tracing externalities as sources of indeterminacy abstract this paper offers further inquiry into sources of indeterminacy in general equilibrium we take a more agnostic approach than previous work as we allow for a more general interpretation of externalities in particular we identify the origin of scale economies as being from either labor or capital we find that in the one sector model it is primarily the externalities associated with labor that generate the result however in the two sector model indeterminacy can be ultimately traced back to the externalities from capital in the investment sector

excess labour and the business cycle a comparative study of japan germany the united kingdom and the united states against the background of firm specific human capital theory this paper investigates empirically the relative propensity of manufacturing industries in japan germany the united kingdom and the united states to hold excess labour over the business cycle both stock and utilization dimensions of the labour input are integrated into the study throughout discussion is linked to earlier research that has analysed the relative international performance of the japanese labour market

external economies as a mechanism of agglomeration in eu manufacturing productive externalities are significant determinants of agglomeration not deeply studied at the industry and international level we analyse the impact on productivity growth of technological externalities both inter and intraindustry national or international at the industry level for the eu countries and the period 1995 2002 the results confirm the advisability of considering international externalities when countries are taken as regions whose omission underestimates national spillovers together with national endowments and a central geographical position the growth of productivity is encouraged by national and international specialization as a general result moreover it is fuelled by stronger interindustry spillovers and productive diversification a result more evident for high technology industries while lower technology industries are more sensitive to the omission of international externalities economic integration seems to be relevant because supranational regions with less frictio

general equilibrium effects of local taxes abstract this paper analyzes the consequences of the property tax and a local sales tax in the context of a spatial general equilibrium model of a closed city with a generalized utility function of the residents and production function of housing the range of effects are different from those obtained earlier by other authors who have generally assumed particular functional forms for example it appears that under certain conditions the property tax can even lead to an increase in metropolitan size alternatively a local sales tax can lead either to an expansion or contraction in city size results obtained are used to analyze the consequences of different types of local tax reforms

sabotage in tournaments evidence from a laboratory experiment although relative performance schemes are pervasive in organizations reliable empirical data on induced sabotage behavior are almost nonexistent we study sabotage in repeated tournaments in a controlled laboratory experiment and observe that effort and sabotage are higher for higher wage spreads additionally we find that also in the presence of tournament incentives agents react reciprocally to higher wages by exerting higher effort destructive activities are reduced by explicitly calling them by their name sabotage communication among principal and agents can curb sabotage when they agree on flat prize structures and increased output if sabotage is not possible the principals choose tournament incentives more often this paper was accepted by peter wakker decision analysis

indeterminacy and fiscal policies in a growing economy this paper studies the dynamic properties of a standard one sector model of endogenous growth with inelastic labor supply in which capital taxes are used to nance public production and consumption services the government is benevolent and chooses its tax policy by taking into account the decentralized competitive equilibrium within this second best setup we establish conditions for multiple balanced growth paths in conjunction with indeterminacy of transitional dynamics the mechanism for global and local indeterminacy is a simple combination of public production services that provide production externalities to private rms and hence cause a wedge between private and social returns public consumption services that provide direct utility to households and endogenously chosen distorting taxes

land use regulations and regional economic development this paper uses a data intensive computable general equilibrium cge model of a medium sized city with integrated commercial and residential land data to analyze changes to local land use regulations via changes in land supply elasticities on economic development measures employment household income housing prices and tax revenue under various types of regional growth that originate from different local sectors the cge framework overcomes difficulties of econometric modeling in this area namely measurement consistency impact isolation and endogeneity issues the results both link the sparse work in this area and provide a systematic analysis including marginal and total impacts

the effect of intervention frequency on the foreign exchange market the japanese experience abstract this paper examines the effects of the frequency of foreign exchange intervention on exchange rate volatility japanese intervention is characterized by differences in the frequency of intervention there are high and low frequency intervention periods using the garch methodology this paper models the changes in the yen dollar exchange rate with the frequency of intervention from april 1991 to december 2005 as the focal explanatory variable the empirical results show that high frequency intervention stabilizes the exchange rate by reducing exchange rate volatility and that low frequency intervention is more effective

the solow residual for australia technology shocks or factor utilization i introduction in macroeconomics a standard way of measuring technology shocks is to use the solow residual solow 1957 however a growing body of evidence suggests the solow residual is at best a noisy measure of technology shocks a number of hypotheses have been advanced as to why this might be the case these include the existence of imperfect competition and increasing returns to scale hall 1988 1990 spillover externalities caballero and lyons 1992 and variations in factor utilization rates basu 1995 burnside 1996 burnside et at 1993 1995a b burnside and eichenbaum 1994 and finn 1995 recent work by basu 1995 and burnside et al 1995a using data for united states u s manufacturing industries suggests that changes in capital utilization are the most likely cause of the mis measurement of technology by the solow residual this paper presents an econometric analysis of the behavior of the solow residual for the australian economy 1 the preliminary analysis examines whether the solow residual for australia can be characterized as a strictly exogenous variable following evans 1992 i test whether the solow residual is grangercaused by a number of other macroeconomic variables including foreign prices and production government spending interest rates and a monetary aggregate fluctuations in such variables are frequently proposed as sources of business cycles in small open economies consistent with results obtained for the u s by evans i find that the solow residual for australia is not a strictly exogenous variable however while evans finds money supply growth and government spending granger cause the u s solow residual neither of these variables is a significant predictor in the australian case for australia the terms of trade and a measure of the term spread have the strongest predictive content for the solow residual what these results indicate is that the standard measure of the solow residual for australia is affected by shocks other than pure technological innovations in an attempt to quantify the contribution of other non technology shocks to fluctuations in the solow residual for australia i employ the structural vector autoregression svar methodology developed by shapiro and watson 1988 blanchard and quah 1989 and cochrane 1994 it is assumed that the measured solow residual is affected by two types of mutually uncorrelated shocks one of these has a permanent effect on the level of the solow residual and the other has only a temporary effect to identify these two disturbances i use information from a second variable capacity utilization where this choice is influenced by the recent work of burnside and eichenbaum 1994 and burnside et al 1995b neither of the two shocks affecting the solow residual has a permanent effect on the level of capacity utilization the shock which has a permanent effect on the solow residual is identified with a true technology disturbance while the other shock is assumed to reflect aggregate demand disturbances the remainder of this paper is organized as follows in section ii a measure of the solow residual for australia is constructed and its predictability examined section iii contains a discussion of the svar model used to analyze the solow residual and capacity utilization the empirical results from this model are presented in section iv section v considers the robustness of the results and section vi concludes ii properties of the solow residual in macroeconomics a standard means of computing the logarithm of the solow residual a sub 1 is to use the following equation 1 a sub t y sub t s sub n n sub t 1 s sub n k sub t where y is the log of aggregate output n is the log of total hours worked k is the log of the aggregate capital stock and s sub n is labour s share of national income assumed to be constant

learning by doing short sightedness and indeterminacy this article introduces firm specific learning by doing into a real business cycle rbc model this assumption results in indeterminacy of the wage over a large portion of the parameter space when firms use sufficiently high discount factors and when newly employed labour is relatively unproductive when firms and households use the same discount factor the effects of indeterminacy are limited to adding volatility to the wage rate if these discount factors differ however then indeterminacy also destabilises newly employed labour and total hours this result helps to explain the high amount of volatility that newly employed labour exhibits in the us data

migration and interregional employment redistribution in the united states during the 1970 s the south and west census regions accounted for 89 9 percent of incremental u s population and 72 5 percent of incremental nonagricultural employment these figures are sharply higher than corresponding figures for any other decade in u s history for example during the 1930 s the south and west gained 65 4 percent of incremental national population which was the highest share previously recorded the immediate cause of the interregional population shifts is fairly heavy net out migration from the northeast and north central regions to the south and west combined with birth rates that are near historical low levels interactive relationships that cause employment growth and migration to reinforce one another are probably operating but these relationships are not well understood they are the focus of this paper using a new and unique set of time series data on migration and employment we develop and estimate a time series model of migration and employment growth for each of 171 u s regions our primary emphasis in this paper is on the 57 major metropolitan

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

procyclical multifactor productivity tests of the current theories this paper conducts various tests of four hypotheses to account for procycical multifactor productivity the hypotheses include imperfect competition increasing returns to scale labor hoarding and thick market externalities the test results provide strong evidence for imperfect competition and increasing returns and weak evidence for labor hoarding and thick market externalities however the markup and returns to scale parameter estimates are much smaller than those noted in previous research this difference results from the use here of gross output and intermediate inputs as opposed to the use in previous research of value added and primary inputs

profiting from agglomeration evidence from the salmon aquaculture industry asche f roll k h and tveteras r profiting from agglomeration evidence from the salmon aquaculture industry regional studies even though most celebrated clusters seem to be in high cost areas many econometric studies represent agglomeration externalities as increased primal productivity or reduced cost while this certainly can be consistent with some observed agglomeration effects it may be insufficient for the growth of a cluster the key condition for this is that profitability is higher the paper tests for agglomeration effects using a profit function approach this may be particularly important for firms in high cost clusters where revenue effects can be as important as productivity and cost effects the paper tests for both intra and inter industry agglomeration externalities using firm level data
