the dynamic effects of government spending policies in a two sector endogenous growth model this paper investigates the impact of government spending policies in a two sector model of endogenous growth endogenous growth arises because all factors of production physical and human capital are reproducible both temporary and permanent government spending shocks are examined the model implies that a permanent lump sum financed increase in government spending raises the long run growth rate this occurs because the negative wealth effects of a spending increase will increase labor supply on the other hand an income tax or wage tax financed rise in government spending reduces the growth rate the output effects of a temporary increase in government spending may be greater or less than a permanent increase in spending copyright 1995 by ohio state university press

all pay war we study a model of conflicts and wars in which the outcome is uncertain not because of luck on the battlefield as in standard models but because countries lack information about their opponent in this model expected resource levels and production and military technologies are common knowledge but realized resource levels are private information each country decides how to allocate its resources to production and warfare the country with the stronger military wins and receives aggregate production in equilibrium both comparative and absolute advantages matter a larger resource share is allocated to warfare by the country with a comparative advantage in warfare at relatively low realized resource levels and by the country with an absolute disadvantage in warfare at relatively high realized resource levels from an ex ante perspective the country with a comparative advantage in warfare is more likely to win the war unless its military potential is much lower

international marketing policy a discussion of the standardization construct and its relevance for corporate policy a fundamental question in international marketing concerns the desirability and feasibility of standardizing marketing programs and procedures internationally the primary objective of this paper is to present an overview and evaluation of the standardization debate central issues of interest include a discussion of the standardization construct and an evaluation of the evidence regarding corporate implementation of standardization strategies

investment and interest rate policy abstract the paper s theorems reverse two standard results of new keynesian economics simply by appending endogenous investment to a benchmark imperfect competition sticky price model our results are a a passive interest rate rule where the monetary authority responds to inflation by lowering the real interest rate implies local equilibrium uniqueness whereas an active rule does not generate a locally unique equilibrium b a temporary exogenous increase in the nominal interest rate causes a temporary increase in output and investment extensions of the benchmark model including generalized preferences and alternative interest rate rules are also examined journal of economic literature classification numbers e12 e31 e52

the tragedy of the commons in a violent world earlier research has shown that the tragedy of the commons may be resolved by folk theorems for dynamic games in this article we graft on a standard natural resource exploitation game the possibility to appropriate the resource through violent means because conflict emerges endogenously as resources get depleted the threat supporting the cooperative outcome is no longer subgame perfect and thus credible the unique equilibrium is such that players exploit noncooperatively the resource when it is abundant and they revert to conflict when it becomes scarce the players utility is shown to be lower even if conflict wastes no resources

energy price shocks and medium term business cycles abstract energy price shocks pose sudden challenges to economies this paper examines how oil price shocks have influenced the u s economy over the last decades and especially focuses on the productivity slowdown in the years following an oil price shock we extend the existing literature by considering medium term business cycles which consist of high frequency components conventional business cycles up to 8 years and medium frequency components 8 50 years we find that the medium frequency consequences of energy price shocks are considerable and explain a significant part of the productivity slowdown

sticky prices and volatile output abstract we examine the effect of introducing a specific type of price stickiness into a stochastic growth model subject to a cash in advance constraint as in previous studies we find the introduction of price rigidities provides a substantial source of monetary non neutrality which contributes significantly to output volatility we show that the introduction of this form of sticky prices improves the model s performance at explaining inflation but worsens it for output the most dramatic failure of the model is the extremely high frequency fluctuations in output that it generates sticky prices not only fail to produce persistent business cycle fluctuations but they generate extreme volatility at very high frequencies

a sheriff two bullets and three problems this paper analyzes deterrence in international conflicts assume a strong country has several opponents and faces a military capacity constraint which is not exhausted after just one war two main effects are at work if the strong country is constrained then reputation is more expensive and may occur less often the problem is that the opponents may but need not be more aggressive compared to a world without a constraint it may be that an axis of evil does not exist before a war occurs but is implicitly formed even by moderate countries after the first war was waged a point of interest is whether the constrained strong country should obtain additional capacity given that the objective is to minimize the number of wars the analysis sheds some new light on the u s foreign policy the united nations and the axis of evil

terms of trade economic growth and trade patterns a small open economy case by incorporating human capital accumulation into a dynamic trade model we examine the relationship between the growth rate and the specialization pattern of a growing economy we found that as long as its autarky price differs from the world price a small open economy eventually specializes completely furthermore the impact of the terms of trade on the growth rate depends on the trade pattern specifically if a country specializes in a capital commodity the growth rate is unaffected by the terms of trade if it specializes in a consumption commodity its growth rate is significantly influenced by the terms of trade

a model of military spending and economic growth this paper investigates a model of militaryconflict between two regimes in which eachmay initiate combat in order to confiscateresources from the other conflict or thepotential for same results in wastefulmilitary spending which lowers growth foreach regime equilibrium military spendingis determined in a one shot game analysisof the one shot game is followed by a studyof the prospects for an equilibrium inwhich regimes lower military spending anddo not engage in combat in repeated play in this latter case military spending willbe decreased to a level just sufficient todeter deviations from the no combatequilibrium this minimum level increases and growth decreases with the internalpolitical instability of each regime moreover an exogenous increase in thedefensive capability of each regime mayeither increase or decrease growth depending upon the initial level ofmilitary spending and growth

money new keynesian macroeconomics and the business cycle abstract we show in this paper that the typical modern business cycle cannot be reduced to the real business cycles archetype a monopolistic competition model with price adjustment costs affected by technological and monetary shocks better mimics the economic fluctuations in two countries with very different cyclical properties namely france and the united states in our model monetary shocks are necessary to reproduce the standard deviation of output the money output correlation the labour productivity worked hours relative standard deviation the labour productivity worked hours correlation and the mark up output correlation with two independent shocks one real more specifically defined than the solow residual and one nominal the model gives an answer to some empirical puzzles which were left unexplained by traditional rbc models

determinacy and identification with taylor rules the new keynesian taylor rule theory of inflation determination relies on explosive dynamics by raising interest rates in response to inflation the fed induces ever larger inflation unless inflation jumps to one particular value on each date however economics does not rule out explosive inflation so inflation remains indeterminate attempts to fix this problem assume that the government will choose to blow up the economy if alternative equilibria emerge by following policies we usually consider impossible the taylor rule is not identified without unrealistic assumptions thus taylor rule regressions do not show that the fed moved from passive to active policy in 1980

anarchy efficiency and redistribution this paper develops a contractarian theory of the state and the existence of redistribution the existence of rules of redistribution is explained without any recourse to the risk aversion of agents no veil of ignorance is needed this avoids obligational problems inherent in most other contractarian theories of justice hence this paper departs from the standard legitimization of redistribution as fundamental insurance and interprets it as stemming from a principle of reciprocity in trade since this paper deals with an anarchic society the implementation of redistributional rules is constrained by the assumption of self enforcement we show that this assumption changes the interpretation of the state the state is characterized by a particular design of equilibrium strategies not by the existence of enforcement agencies

conflict and deterrence under strategic risk we examine the determinants of cooperation and the effectiveness of deterrence when fear is a motive for conflict we contrast results obtained in a complete information setting with those obtained in a setting with strategic risk where players have different information about their environment these two strategic settings allow us to identify and distinguish the role of predatory and preemptive incentives as determinants of cooperation and conflict in our model weapons unambiguously facilitate peace under complete information in contrast under strategic risk we show that increases in weapon stocks can have a nonmonotonic effect on the sustainability of cooperation we also show that under strategic risk asymmetry in military strength can facilitate peace and that anticipated peacekeeping interventions may improve incentives for peaceful behavior

multivariate detrending under common trend restrictions implications for business cycle research abstract this paper outlines a methodology to detrend multiple time series under common trend restrictions the same filters used to construct the estimated trend in univariate exercises are shown to be appropriate in multivariate studies with a single common trend however to estimate the common trend in the multivariate case the filter is applied to a linear combination of series rather than to each series individually an empirical example and simulation exercises illustrate the implications of common trend detrending for measurement of business cycle properties

the role of energy in real business cycle models abstract this paper modifies hansen s 1985 analysis of a real business cycle mode with indivisible labor by explicitly including energy as a productive input and modelling the relative price of energy as an exogenous random process one goal is to determine the extent to which the introduction of energy price shocks reduces the reliance of the real business cycle model on unobserved technology shocks the other goal following christiano and eichenbaum 1991 is to compare the correlation between real wages and hours predicted by the energy inclusive model to that predicted by hansen s model

how well do linear approximation methods work abstract in this paper we investigate the accuracy of approximating policy functions for three different approximation methods in the context of a neoclassical model with a production tax we find that a variant of the king plosser and rebelo procedure yields the best approximations overall but that in certain instances researchers may be better off using a discrete state space solution to the euler equations of the model

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

the arms trade and the stability of regional arms races abstract arms sales to countries involved in regional conflicts raise a range of pressing policy issues this paper models the interaction between two potentially hostile countries who spend their national income on arms imports and consumption goods their welfare depends on consumption and military security military security is a function of relative arms stocks and depends on the relative advantages of aggressive and defensive strategies we examine the dynamic game for noncooperative and regional arms control regimes an innovation of the paper is the inclusion of the price of arms which proves to have a major effect on the stability of arms races

a dynamic model of conflict and appropriation abstract this paper presents an extension of a static model of economic conflict analyzed by hirshleifer 1991 1995 and skaperdas 1992 to an infinite horizon differential game our aim is to highlight the strategic role of appropriation among a smaller group of agents in an intertemporal context the model yields the conclusion that there exists a unique linear nonlinear markov perfect equilibrium strategy even when strategies are defined over the entire state space we demonstrate that partial cooperation can be seen as a long run response to conflict moreover a decrease in the effectiveness of appropriation the depreciation rate of a common pool stock the rate of time preferences or an increase in the degree of noise improves the degree of partial cooperation and thus welfare in an anarchic society

a model of advertising standardization in multinational corporations although there have been several studies concerning the issue of advertising standardization few authors have proposed an integrated model of the determinants of advertising standardization even if the extent of control of multinational corporations mnc over their subsidiaries is often cited as a key element in the determination of the level of advertising standardization adopted by the mncs there is no consistent view concerning the role of this variable this paper attempts to clarify these points by proposing at the mnc level a measurement model and a structural model for the determinants of the degree of advertising standardization in this model the mediation effect of the mnc s degree of control over the subsidiary is tested and validated in addition the measurement instruments used for the determinants are confirmed

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

productivity growth consumer confidence and the business cycle abstract the objective of this paper is to provide in the context of a dynamic general equilibrium model an answer to the following five questions 1 to what extent does an economy subject to regular variations in labor productivity growth differ from one where labor productivity is constant 2 what is the impact on major macro indicators of a one time change in labor productivity growth 3 what are the business cycle implications of autonomous non falsifiable changes in growth expectations 4 what is the potential of such expectation changes for explaining the volatility of consumption to output ratio 5 can autonomous changes in growth expectations help us understand recent business cycle episodes

product and promotion adaptation in export ventures an empirical investigation while the desirability of marketing adaptation vs standardization has long been debated within both academic and business circles empirical studies investigating the conditions under which each strategy becomes appropriate have been rare this article provides a formal investigation of the correlates of product and promotion adaptation in export ventures a conceptual framework of product and promotion adaptation in export ventures is proposed to integrate the diverse perspectives on the issue of standardization versus adaptation the conceptual framework is further specified in a testable form and tested via data collected by a series of in depth personal interviews with export marketing managers the results support the contingency perspective recently emerging in the standardization literature and suggest that the degree of the various aspects of product adaptation i e upon and after entry and promotion adaptation i e positioning packaging labeling and promotional approach are significantly influenced by company product industry and export market characteristics however the profile of the correlates varies across the various aspects of product and promotion adaptation

arming as a strategic investment in a cooperative equilibrium to develop a positive economic theory of military spending this analysis focuses on a game theoretic general equilibrium model of international conflict in which consumption peaceful investment and military spending are endogenously determined the analysis illustrates that when there is repeated interaction between nations a game of threats and punishments generally will not support a disarmament outcome and that fluctuations in military spending can be an endogenous result of fluctuations in aggregate economic activity furthermore the analysis shows how the relation between aggregate economic activity and military spending qualitatively depends on whether governments are acting opportunistically or cooperatively copyright 1990 by american economic association

endogenous destruction in conflict theory and extensions this article develops a general equilibrium model of conflict to characterize the implications of endogenous destruction for bargaining and fighting specifically we consider the scenario where two contending parties engage in bargaining to avoid fighting when there are direct costs e g arms buildups and indirect costs e g destruction to consumable resources of conflict without imposing specific functional form restrictions on conflict production and destruction technologies we show their interactions in determining an optimal decision between fighting and bargaining we find that under the shadow of conflict bargaining is costly as the contending parties always allocate more resources to arming for guarding settlement through bargaining than in the event of fighting in contrast to conventional thinking that bargaining is pareto superior over fighting we show conditions under which fighting dominates bargaining as the nash equilibrium choice the positive analysis may help explain the general causes of fighting without resorting to the assumption of incomplete information or misperceptions jel d74 h56 c7

investment interest rate policy and equilibrium stability abstract carlstrom and fuerst 2005 investment and interest rate policy a discrete time analysis journal of economic theory 123 4 20 show that in the presence of investment activity and price stickiness indeterminacy of equilibrium is induced by forward looking monetary policy that sets the interest rate in response only to future inflation in a stochastic version of their model we find that this indeterminacy problem is due to a cost channel of monetary policy whereby inflation expectations become self fulfilling and the problem can be overcome once the forward looking policy responds also to current output or contains sufficiently strong interest rate smoothing since this prevents the self fulfilling expectations we also show that when e stability is adopted as the selection criterion from multiple equilibria even the forward looking policy generates a locally unique non explosive e stable fundamental rational expectations equilibrium as long as the policy response to expected future inflation is sufficiently strong

comparative marketing the first twenty five years this article reviews the field of comparative marketing in terms of scope types and depth of studies methodological issues conceptual and managerial payoffs and teaching approaches after its first quarter of a century as an international business topic comparative marketing is still relatively green

deterrence in contests this paper explores the role of deterrence in contests as a general rule we show that for a deterrence strategy to be played by rational agents it is necessary that the contest be destructive we show for a very general class of functions that pure strategy deterrence equilibria where contestants deter one another do not exist a corollary of this finding is that under fairly general conditions agents should always be expected to engage in contests applied to international relations our results imply that war is always a potential outcome despite deterrence attempts

monk mortgages in a new keynesian model abstract there has been much interest recently in the role of household long term mortgage debt in the transmission of monetary policy this paper offers a tractable framework that integrates the long term debt channel with the standard new keynesian channel providing a tool for monetary policy analysis that reflects the recent debates in the literature as there is a nontrivial role in the model for both short and long term debt it provides a laboratory to investigate the effects of monetary policy operating not only through its current short term actions but also through expected persistent changes in its stance

perfectly secure property rights and production inefficiencies in tullock contests from the point of view of institutional economics property rights are an instrument to shape individual incentives efficiently for the case of a tullock contest with endogenously determined rent i analyze the circumstances under which perfectly secure property rights emerge in an economy where the security of property is endogenously determined i analyze different sequential structures for the determination of defensive and appropriative investments and determine the equilibrium sequence of moves if the sequential structure is endogenous it turns out that in subgames where perfectly secure property rights emerge incentives for production are still inefficient in addition it can be shown that the endogenous determination of moves leads to a sequence of events that result in open conflict even if perfectly secure property rights would have been an alternative

some consequences of temporal aggregation in empirical analysis i derive the generating mechanism of a temporally aggregated process when the disaggregated one belongs to the vector autoregressive integrated moving average class i then study the effects of temporal aggregation on a set of characteristics of usual interest such as exogeneity causality cointegration and common features an empirical example with canadian interest rates illustrates the main issues

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

ethnic diversity civil war and redistribution in a game theoretic framework we analyse the circumstances under which self enforcing redistribution and power sharing coalitions can be used to peacefully resolve ethnic conflict the existence of a pacific equilibrium depends crucially on ethnic diversity the number of ethnic groups the risk of civil war is comparatively high at intermediate levels of ethnic diversity the risk is low if a society is either very homogeneous or very diverse predictions of the model are consistent with evidence on the incidence of civil war

the distribution of income in the presence of appropriative activities we examine the distribution of income when agents allocate their initial endowments between production and appropriation arms investments influence or rent seeking activities final output depends on the productive contributions of the agents but is divided between them according to their relative contributions in appropriation various possible improvements in an agent s useful productivity reduce the agent s equilibrium share of income but increases in initial endowments increase an agent s share we contrast our results to those that would obtain in the competitive counterpart to our model and discuss its relevance both for history and for the present the results extend to a class of models where distribution is determined between two groups of agents with agents within each group behaving non cooperatively but without exhibiting the free rider problem

learning about monetary policy rules abstract we study macroeconomic systems with forward looking private sector agents and a monetary authority that is trying to control the economy through the use of a linear policy feedback rule we use stability under recursive learning a la evans and honkapohja learning and expectations in macroeconomics princeton university press princeton new jersey 2001 as a criterion for evaluating monetary policy rules in this context we find that considering learning can alter the evaluation of alternative policy rules

robust control of forward looking models abstract this paper shows how to formulate and compute robust ramsey aka stackelberg plans for linear models with forward looking private agents the leader and the followers share a common approximating model and both have preferences for robust decision rules because both doubt the model since their preferences differ the leader s and followers decision rules are fragile to different misspecifications of the approximating model we define a stackelberg equilibrium with robust decision makers in which the leader and follower have different worst case models despite sharing a common approximating model to compute a stackelberg equilibrium we formulate a bellman equation that is associated with an artificial single agent robust control problem the artificial bellman equation contains a description of implementability constraints that include euler equations that describe the worst case analysis of the followers as an example the paper analyzes a model of a monopoly facing a competitive fringe

the monetary transmission mechanism an empirical framework this paper provides an overview of the monetary transmission mechanism describing the impact of changes in monetary policy on real gdp changes in financial market prices including long term interest rates and exchange rates are the main vehicle for the transmission of policy the framework incorporates rational expectations and policy rules it is empirical and appears to fit the facts well

war politics an economic rational voter framework the frequency of foreign conflict initiations in the united states is found to be significantly greater following the onset of recessions during a president s first term than in other periods the authors develop an economic theory of the political use of wars which links the election cycle war decisions and economic performance consistent with the observed relationships among these events an incumbent leader with an unfavorable economic performance record may initiate a war to force the learning of his war leadership abilities and thus salvage with some probability his reelection this obtains despite voter rationality and informational symmetry copyright 1995 by american economic association

the economic crisis from a neoclassical perspective abstract this paper assesses the 2007 2009 recession using neoclassical business cycle theory i find that the 2007 2009 u s recession differs substantially from other postwar u s recessions and also from the 2008 recession in other countries in that lower labor input accounts for virtually all of the decline in income and output in the united states while lower productivity accounts for much of other u s recessions and the 2007 2009 recession in other countries i also find that existing classes of models including financial market imperfections models do not explain the u s recession this is because the 2007 2009 recession is almost exclusively related to what appear to be labor market distortions that drive a wedge between the marginal product of labor and the marginal rate of substitution between consumption and leisure a topic about which current classes of financial imperfection models are largely silent i discuss future avenues for developing this class of models and i consider alterna

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

workers warriors and criminals social conflict in general equilibrium we incorporate appropriation activities social conflict into canonical models of trade and study how economic shocks and policies affect the intensity of conflict we show that not all shocks that could make society richer reduce conflict positive shocks to labor intensive industries diminish conflict while positive shocks to capital intensive industries increase it the key requirement is that conflict activities be more labor intensive than the economy as this determines how shocks affect the returns and costs of conflict our theory is consistent with several observed patterns of conflict and implies that empirical work should take into account the relative factor intensities of the productive and conflict sectors in each country incorporating appropriation into a canonic general equilibrium model affects what policies may be deemed desirable in order to reduce conflict and generate pareto improvements policy must be distortionary while reforms that appear efficiency enhancing under the unrealistic assumption of perfect property rights may backfire this offers one explanation for why reforms based on traditional models without appropriation may be delayed and become unpopular when implemented and why societies may sympathize with seemingly inefficient redistribution

average marginal tax rates from social security and the individual income tax we extend previous estimates of the average marginal tax rate from the federal individual income tax to include social security our computations consider the tax rates on employers employees and the self employed the income that accrues to persons with earnings below the ceiling and the effective deductibility of employers social security contributions from workers taxable income the next effect of social security on the average marginal tax rate is below 02 until 1966 but then rises to 03 in 1968 04 in 1973 05 in 1974 06 in 1979 and 07 in 1982 this abstract was borrowed from another version of this item

straight time and overtime in equilibrium abstract we formulate an equilibrium model of straight time and overtime wages by imposing restrictions on agents consumption sets and using a commodity space that includes employment lotteries we extract some time series implications from a linear quadratic approximation to our model evaluated at particular parameter values we use our model informally to interpret some features of observed time series for wages and employment

self interest and national security the inner mechanism of global competition remains much as adam smith defined it two centuries ago nations interact while seeking to win by gaining higher wealth self interest in gaining wealth drives the process although wars and other deviations often occur in this setting economic concepts of competition benefit cost criteria and risk can help in defining efficient choices among policy tools including military activities from research using those concepts my study with theodora shepherd 1986 1 will discuss several tentative conclusions about the u s ussr rivalry 1 the global competitive process let us call it process 1 has properties which appear to make it stable 2 the united states and ussr appear to possess inherent security from conquest by each other 3 each country s efficient limit on military spending can be analyzed as an analog of payments for insurance to raise national security in that context inherent security reduces the u s and ussr s efficient levels of armaments 4 military entropy occurs global wealth is subject to a general process process 2 which subtracts it into military forms and warfare

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

the relative adjustment of wages and prices direct tests within a multiple equation system in order to assess the relative rigidity of the aggregate price level and the nominal wage rate most researchers have focused on the implied behaviour of the real wage rate in response to a purely demand disturbance the present work examines the explicit behaviour of the two variables and is therefore able to analyse the variables short run responses within the context of their defined long run behaviour while the paper reports evidence of long run stability in the real wage rate additional evidence is presented which supports both sticky price and sticky wage models the determining factor is the choice of lag

human capital formation and business cycle persistence abstract in this paper we examine the role of the formation of human capital in propagating shocks over the business cycle we show that a two sector equilibrium business cycle model with human capital is able to generate persistence in the growth of output and other aggregate variables comparable to that observed in the post war us data a key feature is the relatively low elasticity of substitution between skilled and unskilled labor in the production of human capital

sourcing strategies of european and japanese multinationals a comparison based on a typology of sourcing strategies this study identifies various sourcing patterns adopted by european and japanese multinational manufacturing firms in serving the u s market the study has found that the product s market performance is not at all related to its life cycle stage in world trade or to production location but is positively related to the internal components sourcing and negatively related to the product adaptation the findings strongly support levitt s call for a global product

prosperity without conflict abstract social conflict and slow growth are features of many developing economies this paper considers the role institutions of property rights and conflict management can play in both achieving prosperity and mitigating conflict in these economies we study how introducing conflict over economic distribution into an otherwise standard model of growth can shape optimal second best taxation policy when diversionary activities cannot be taxed in this context we find that the maximization of economic efficiency may call for a reduction in growth in order to mitigate the problem of diversion even though the economy s growth is inefficiently slow in the absence of taxation this is so when institutional quality is sufficiently poor but not otherwise the paper warns against the conventional justification of growth promoting policies on efficiency grounds independently of institutions

on the mechanics of new keynesian models abstract the monetary transmission mechanism in new keynesian models is put to scrutiny we show that contrary to the conventional view the transmission mechanism does not operate through the real interest rate channel instead equilibrium inflation is approximately determined as in a flexible price model output is then pinned down by the new keynesian phillips curve the real rate only reflects the feasibility to keep consumption smooth when income changes contractionary monetary policy shocks reducing output and inflation are consistent with an increase decline or no change in the real rate consistency with the real rate channel is observational not structural

sticky price models and durable goods the inclusion of a durable goods sector in sticky price models has strong and unexpected implications even if most prices are flexible a small durable goods sector with sticky prices may be sufficient to make aggregate output react to monetary policy as though most prices were sticky in contrast flexibly priced durables with sufficiently long service lives can undo the implications of standard sticky price models in a limiting case flexibly priced durables cause monetary policy to have no effect on aggregate output our analysis suggests that durable goods prices are the most relevant data for calibrating price rigidity jel e21 e23 e31 e52

the cultural relativity of organizational practices and theories this paper summarizes the author s recently published findings about differences in people s work related values among 50 countries in view of these differences ethnocen tric management theories those based on the value system of one particular country have become untenable this concept is illustrated for the fields of leadership organization and motivation a key issue for organization science is the influence of national cultures on introduction management twenty or even 10 years ago the existence of a relationship be management and tween management and national cultures was far from obvious to many and it national cultures may not be obvious to everyone even now in the 1950s and 60s the dominant be lief at least in europe and the u s was that management was something univer sal there were principles of sound management which existed regardless of na tional environments if national or local practice deviated from these principles it was time to change local practice in the future the universality of sound manage ment practices would lead to societies becoming more and more alike this ap plied even to the poor countries of the third world which would become rich as well and would be managed just like the rich countries also the differences be tween management in the first and second world capitalist and socialist would disappear in fact under the surface they were thought to be a lot smaller than was officially recognized this way of thinking which dominated the 1950s and 60s is known as the convergence hypothesis during the 1970s the belief in the unavoidable convergence of management prac tices waned it was too obviously in conflict with the reality we saw around us at the same time supranational organizations like the european common market which were founded very much on the convergence belief had to recognize the stubbornness of national differences even within existing nations regional dif ferences became more rather than less accentuated the welsh the flemish the basques the bangladeshi the quebecois defended their own identity and this was difficult to reconcile with a management philosophy of convergence it slowly became clear that national and even regional cultures do matter for management the national and regional differences are not disappearing they are here to stay in fact these differences may become one of the most crucial problems for man agement in particular for the management of multinational multicultural orga nizations whether public or private

investment under uncertainty in dynamic conflicts this paper analyses a model in which two groups repeatedly compete with each other for a prize in every time period we assume that there is a status quo bias if there is a fight today yesterday s winner is in a stronger position than the other group hence a change of the status quo has long term consequences that groups need to take into account important applications of this model include lobbying for legislation and political transitions through revolutions we analyse the strategic timing of attacks on the status quo which is similar to investment decisions under uncertainty we find that the attack threshold is considerably lower than in a comparable one period game and that the expenditure level necessary to change the status quo is low in comparison to the prize this provides a possible solution to tullock s rent seeking paradox in lobbying copyright 2006 wiley blackwell

war and conflict in economics theories applications and recent trends we review the main economic models of war and conflict these models vary in details but their implications are qualitatively consistent highlighting key commonalities across a variety of conflict settings recent empirical literature employing both laboratory and field data in many cases confirms the basic implications of conflict theory however this literature also presents important challenges to the way economists traditionally model conflict we finish our review by suggesting ways to address these challenges

macroeconomic modeling for monetary policy evaluation we describe some of the main features of the recent vintage macroeconomic models used for monetary policy evaluation we point to some of the key differences with respect to the earlier generation of macro models and highlight the insights for policy that these new frameworks have to offer our discussion emphasizes two key aspects of the new models the significant role of expectations of future policy actions in the monetary transmission mechanism and the importance for the central bank of tracking of the flexible price equilibrium values of the natural levels of output and the real interest rate we argue that both features have important implications for the conduct of monetary policy

the macroeconomics of dr strangelove the cold war has ended and president george bush has declared the beginning of a 4 new world order this new world order has so far been characterized by the intensification of regional disputes civil strife and civil war its implications for arms proliferation and arms control are still unclear this paper considers both superpower conflict and the transition to international cooperation in the context of a model that emphasizes intergenerational linkages specifically we explore the weapons accumulation decisions of two adversarial countries in the context of a deterrence conflict initiation game embedded in an overlapping generations model the demographic structure of the overlapping generations model allows the analysis of both between and withincountry intergenerational external effects caused by past weapons accumulation decisions while the two country setting permits consideration of international external effects caused by the adversary country s current weapons accumulation decision we analyze the noncooperative equilibrium and then consider the effects of a regime change characterized by international cooperation but where the intergenerational externali

social composition social conflict and economic development this article investigates how the existence of non cooperative social groups that appropriate resources either peacefully or through contest affects economic growth when property rights are unenforceable for symmetric groups it shows that economic growth is generated only in peaceful societies for the case of asymmetric groups rebel equilibria are investigated in which a large majority behaves peacefully although challenged by an aggressive minority the article explains how conflict intensity and the rate of economic growth depend on social fractionalisation general productivity of the economy power of social elites and the ease at which resources are appropriated

can the shadow of the future harm cooperation abstract it is generally thought that in long term relationships high valuations of the future are conducive to cooperation in an intertemporal model of conflict however we demonstrate the possibility of the opposite effect a longer shadow of the future may harm cooperation in particular we show that the degree of inefficiency is positively related to i the agents valuation of the future ii potential growth rates in resources iii the size of initial resource endowments and iv the effectiveness of conflict

estimating and testing rational expectations models when the trend specification is uncertain abstract this paper explores various strategies for estimating and testing rational expectations models when the trend specification is uncertain one approach seeks to make estimators and tests robust to trend misspecification by reducing the influence of low frequency dynamics however contrary to intuition the effects of trend specification errors are not confined to low frequencies but are spread across the entire frequency domain thus operations that damp low frequency components do not remove trend specification errors and are not sufficient for constructing robust estimators and tests another approach seeks representations of approximating models that do not condition on a specification of the trend and it uses gmm to estimate parameters and test over identifying restrictions because these methods do not condition on assumptions about trends they are robust to errors in that part of the approximating model

conflict war and redistribution this article analyzes the circumstances under which conflict leads to the outbreak of war using a formal model which incorporates both the redistribution of resources as an alternative to war and imperfect information countries act as rational agents concerned with both consumption and the public bad of a war in the first period both countries can either consume or build arms whereas in the second period there can be either the threat or the use of force to reallocate resources if both countries are fully informed then there will be no war but rather a voluntary redistribution of resources in a situation of asymmetric information however in which one country is fully informed and the other is not a war can occur if the uninformed country uses a separating equilibrium strategy precommitting itself to a positive probability of war in order to prevent bluffing by the informed country

technology of military conflict military spending and war abstract this paper studies how the technology of military conflict affects the allocation of resources in military spending guns and productive investment butter we first identify the fundamental property of conflict technology which the two commonly used contest success functions the difference and ratio forms share using this property named the constant elasticity of augmentation we construct a new class of contest success functions hence generalizing the two forms we provide axiomatic and probabilistic characterizations of the new contest success function then adopting the new contest success function we study how the elasticity of augmentation affects the trade off between guns and butter and countries international policy to settle or wage a war finally we estimate the elasticity of augmentation using actual battle data including seventeenth century european battles and world war ii battles and explore the implications of the estimated parameters of military technology on military spending and the preference of settlement

the macroeconomic consequences of terrorism abstract we perform an empirical investigation of the macroeconomic consequences of international terrorism and interactions with alternative forms of collective violence our analysis is based on a rich unbalanced panel data set with annual observations on 177 countries from 1968 to 2000 which brings together information from the penn world table data set the iterate data set for terrorist events and data sets of external and internal conflict we explore these data with cross sectional and panel growth regression analysis and a structural var model we find that on average the incidence of terrorism may have an economically significant negative effect on growth albeit one that is considerably smaller and less persistent than that associated with either external wars or internal conflict as well terrorism is associated with a redirection of economic activity away from investment spending and towards government spending however our investigation also suggests important differences both regarding the incidence and the economic consequences of terrorism among different sets of countries in oecd economies in particular terrorist incidents are considerably more frequent than in other nations but the negative influence of these incidents on growth is smaller

investment and interest rate policy a discrete time analysis this paper analyzes the restrictions necessary to ensure that the interest rate policy rule used by the central bank does not introduce local real indeterminacy into the economy it conducts the analysis in a calvo style sticky price model a key innovation is to add investment spending to the analysis in this environment local real indeterminacy is much more likely in particular all forward looking interest rate rules are subject to real indeterminacy

cyclical uncertainty precautionary saving and economic growth this paper studies the interaction between cyclical uncertainty precautionary saving and economic growth in a stochastic endogenous growth model the analysis provides insight into the potential connection between technological uncertainty of the sort popularized in real business cycle models and the determinants of economic growth in a stochastic version of a popular model of endogenously determined economic growth the magnitude of the link between cyclical uncertainty and growth is quantified and found to be small in terms of its effect on the growth rate but possibly large in terms of its effect on levels of macroeconomic variables moreover the welfare costs of reduced cyclical uncertainty can be substantial owing to the lower historical rate of capital accumulation induced by a decrease in precautionary saving the chief implications of the model are found to be roughly consistent with the postwar experience of several countries although the predictions of the model with regard to growth rates are too small to explain much of the variation in growth rates across time or across countries

swords or plowshares a theory of the security of claims to property this paper develops a general equilibrium model of the allocation of resources among appropriative and productive activities the model emphasizes the distinction between offensive weapons which are the instruments of predation and fortifications which provide defense against predation the analysis of this model shows how the equilibrium security of claims to property is determined the analysis focuses on the possibility of a nonaggressive equilibrium in which no resources are allocated to offensive weapons and claims to property are fully secure we also analyze the complex relation between economic welfare and the security of claims to property we find for example that a relatively poor agent could be better off in an equilibrium with less secure claims to property

a european defence union a european defence union jacques fontanel and ron smith the end of the cold war the unification of germany and the removal of us troops has rekindled interest in european defence cooperation the ec has common security policies on its agenda the military role of the weu is being enhanced and the new nato strategy emphasizes multilateral european forces a european defence union offers large potential efficiency gains power like any natural monopoly is generated more effectively and more cheaply by joint forces than by the sum of fragmented individual forces there are also large economies of scale in weapons production trends in budgets costs and threats are making national provision problematic and national arms industries non viable an edu may appear more attractive than either spending vast sums to attain minimum efficient scale or relying on forces that are so small and ill equipped as to require either dependence on the us or acceptance of effective neutrality however an edu reduces national sovereignty poses problems of command control and organization risks free riding and adverse reactions by the us and ussr and is vulnerable to exploitation and rent seeking by military industrial interests this paper examines the economics of these issues and suggests a route towards effective cooperation

information constrained insurance the revelation principle extended abstract private information induced incentive constraints can cause allocations to diverge from full information optimal allocations often in the direction of limited insurance but can bring unanticipated anomalies related plausible contract exclusion restrictions can be damaging in welfare terms more generally private information optimal allocations can be sensitive to the information structure suggesting that the latter be specified with an eye toward realism as well as tractability in an effort to make tractability less of a constraint the paper shows how two apparently difficult information structures a costly state verification environment and a multiperiod multilateral private information environment can be handled theoretically by revelation principle methods the paper also shows how solutions can be generated numerically

balanced budget rules and aggregate instability the role of consumption taxes it is known that in a real business cycle model with constant returns to scale and a balanced budget fiscal policy rule steady state indeterminacy may arise due to endogenous labour income tax rates this article shows that when the government finances its expenditures via an endogenous consumption tax instead a steady state is always saddle path stable consequently combining income taxes with consumption taxes makes the ranges of indeterminacy shrink thus reducing the possibility of aggregate instability from a policy perspective the results provide an additional argument in favour of consumption taxes in place of capital taxes

the workweek of capital and its cyclical implications abstract the neoclassical growth model studied in the kydland and prescott time to build paper is modified to permit the capital utilization rate to vary the effect of this modification is to increase the amplitude of the aggregate fluctuations predicted by theory as the equilibrium response to technological shocks if following solow the changes in output not accounted for by changes in the labor and tangible capital inputs are interpreted as being the technology shocks the statistical properties of the fluctuations in the postwar united states economy are close in magnitude and nature to those predicted by theory

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

family labor supply and aggregate fluctuations abstract this paper considers an economy which is populated by a continuum of identical families consisting of two members the two members have different productivities and the family faces a fixed utility cost if both members supply labor simultaneously although both family members have the same preferences they display very different elasticities of labor supply a real business cycle model is calibrated and it is seen that this cross sectional heterogeneity results in interesting forms of aggregation bias
