toward a reconstruction of keynesian economics expectations and constrained equilibria a two period model of temporary equilibrium with rationing is presented paying particular attention to agents expectations of future constraints it is shown that with arbitrary constraint expectations many different types of current equilibrium may be consistent with the same set of current and expected future wages and prices and that constraint expectations exhibit bootstraps properties e g a higher expectation of keynesian unemployment tomorrow increases the probability that it will prevail today in addition the concept of rational constraint expectations i e perfect foresight of future constraints is introduced and shown to enhance rather than reduce the effectiveness of government policy

macroeconomic interdependence under capital controls abstract this paper studies the international transmission of monetary and fiscal disturbances under capital controls the results are contrasted with those that obtain under perfect capital mobility under perfect capital mobility permanent and unanticipated changes in domestic fiscal and monetary policies have no real effects abroad and the adjustment is instantaneous in contrast under capital controls these disturbances are transmitted abroad and adjustment occurs only over time the dynamic adjustment of the world economy is characterized by a negative co movement of domestic and foreign variables such as consumption the real interest rate and the real exchange rate

tournaments with midterm reviews in many tournaments investments are made over time the question whether to conduct a review once at the end or additionally at points midway through the tournament is a strategic decision if the latter course is chosen then the designer must establish both a rule for aggregating the results of the different reviews and a rule for determining compensations we first study the case of a fixed exogenously given prize and then extend the analysis to the case where the prize is not fixed but may vary with the tournament s outcome it is shown that 1 it is always optimal to assign a higher weight to the final review 2 this weight increases with the dominance of the first stage effort in determining the final review s outcome when the prize is not fixed the optimal design generates an asymmetric tournament in the second stage that favors the winner of the midterm review

fiscal policy coordination with demand spillovers and unionised labour markets we explore the incentives for governments to cooperate by expanding expenditure we have three countries two are in a monetary union the emu the labour markets of both the emu countries are unionised and there is involuntary unemployment in equilibrium we explore the intra and intercountry effects of changes in bargaining power we then examine optimal government expenditures in each emu country we find that there is a positive spillover and that expenditures are strategic complements the coordinated equilibrium involves higher expenditure than the uncoordinated equilibrium

effects of budgetary policies in open economies the role of intertemporal consumption substitution an economy s optimal response to temporary and anticipated future changes in government spending is examined in the context of a two country model which highlights the role of the elasticity of int

issue costs in the eurobond market the effects of market integration this study compares the issuance costs of eurobonds before and after the completion of the economic and monetary union emu in 2002 we find that the introduction of the euro has significantly reduced the issue cost of euro denominated bonds compared to bonds denominated in the legacy currencies the reduction in issue cost is not due to a decrease in underwriter compensation but rather to the elimination of underpricing the difference between the market price after trading commences and the offering price underwriter fee has declined substantially after the completion of the emu but this decline has been offset by an increase in underwriter spread the difference between the offering price and the guaranteed price to the issuer leaving total underwriter compensation unchanged the emu is also associated with significant reductions in bond maturity and syndicate size consistent with its expected effects on liquidity and issue costs in the eurobond market

employment policies wage formation and trade union behavior in a small open economy a model of trade union determined wages is developed which provides an explanation of underemployment based on optimizing behavior it is shown that fiscal policy will in general affect employment under perfect foresight and immediate wage flexibility future consequences of short run stabilization policies are discussed ratchet effects with respect to government expenditure and game theoretic interdependence between government and trade union behavior are emphasized if the trade union takes short run policy measures in order to increase employment as an indication of an employment stabilization rule the future behavior of the trade union changes and the result may be a decrease in long run employment

non traded goods and the international transmission of fiscal policy abstract this paper looks at the effect of non traded goods on the international transmission of fiscal policy intertemporal movements in the price of non traded goods affect real interest rates differentially between countries the real interest rate effects of a fiscal expansion depend crucially upon both the composition of fiscal spending and the intertemporal elasticity of substitution with a high intertemporal elasticity of substitution in consumption a temporary fiscal expansion on non traded goods will lead consumer real interest rates to move in opposite directions between countries

international fiscal policy transmission the paper examines international transmission of stochastic fiscal policy disturbances in a two country general equilibrium framework with possible excess supply equilibria with underutilization o

contests with multiple rounds this paper studies contests where players have the flexibility to add to their previous efforts after observing their rivals most recent effort in an intermediate stage it is found that 1 contrary to previous findings the stackelberg outcome where the underdog leads and the favorite follows cannot be an equilibrium 2 there are multiple subgame perfect equilibria all occurring on the underdog s usual one shot reaction function in between and including the one shot cournot nash and stackelberg outcome with the favorite leading 3 the total equilibrium effort is typically greater than or equal to what a one shot cournot nash play would predict and 4 in settings where players can choose whether or not to disclose their early actions to the rival both the favorite and the underdog disclose in equilibrium applications in sports lobbying and r d races are discussed

on the determination of the external debt the case of israel abstract this paper pursues the econometric implementation of an intertemporal optimization model of the foreign debt with israeli data in this model the private sector faces perfect capital markets and maximizes utility from consumption over an infinite horizon the intertemporal budget constraint recognizes the intertemporal finance equation of the government under these conditions the effect of current disturbances in output government spending and unilateral transfers on private consumption and foreign borrowing is determined by their perceived future persistence the model passes a formal econometric test however some results are also suggestive of omitted considerations

trying to explain home bias in equities and consumption investors hold a substantially larger proportion of their wealth portfolios in domestic assets than standard portfolio theory would suggest a phenomenon called equity home bias in the absence of this bias investors would optimally diversify domestic output risk using foreign equities therefore consumption growth rates would tend to co move across countries even when output growth rates do not empirically however consumption growth rates tend to have a lower correlation across countries than do output growth rates a phenomenon i call consumption home bias in this paper i discuss these two biases and their potential relationship as suggested by the literature

inflation interest rates and welfare this paper develops a simple general equilibrium model of a monetary economy with a capital market money demand arises from a cash in advance constraint rather than from any direct role in the utility function and uncertainty gives rise to a meaningful portfolio choice between money and bonds we show that velocity is increasing in the rate of inflation and that the optimal monetary policy is that which maximizes real balances we also show that the real rate of interest is not invariant to monetary policy inflation lowers the real rate

fiscal spending the terms of trade and real interest rates this paper investigates the international movements in real interest rates and investment spending in response to a temporary fiscal expansion in one country it is shown that fiscal expansion may lead investment spending to be negatively correlated across countries this is because real interest rates relevant for investment purposes may move asymmetrically between countries in response to an expansion in fiscal spending the crucial factors which determine whether or not this occurs are a a transfer criterion which depends upon the spending propensities of the government relative to those of private consumers and b the intertemporal elasticity of substitution in consumption

competition among contests when several contests compete for the participation of a common set of players a contest s allocation of prizes not only induces incentive effects but also participation effects our model predicts that an increase in the sensitivity with which contest outcomes depend on players efforts makes flatter prize structures more attractive to participants in equilibrium contests that aim to maximize the number of participants will award multiple prizes if and only if this sensitivity is sufficiently high moreover the prize awarded to the winner is decreasing in the contests sensitivity we provide empirical evidence from professional road running using race distance as a measure of sensitivity we show that steeper prize structures are more attractive to top ranked runners in longer that is less sensitive races in line with our theory longer races do in fact offer steeper prize structures

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

creating balance in dynamic competitions abstract we consider incentives for organizing competitions in multiple rounds focusing on situations where there is heterogeneity among the contestants ex ante which discourages effort in a single contest heterogeneity evolves across rounds depending upon the outcomes of previous rounds we present conditions under which balance in such a competition can be created by determining the number of rounds and dividing the prize fund carefully across them so that full rent dissipation entails in the model each round is an all pay auction where contestants differ in their abilities to gain a momentum from winning we also discuss the case when negative prizes are feasible demonstrating that this strengthens the full dissipation result and we consider a case where the size of the winner s momentum is related to the size of the prize attained showing that the stronger this linkage the less of the prize is awarded early on

an exploration in the theory of exchange rate regimes three exchange rate regimes a float a one sided peg and a cooperative peg are evaluated and compared in terms of efficiency and welfare levels the framework of analysis embodies country specific monies with the money of each country being used to transact in its commodity markets and its currency denominated bonds welfare levels depend only on consumption levels in the presence of perfect foresight all equilibrium allocations are pareto efficient in a floating exchange rate regime the perfect foresight equilibrium allocation coincides with an equilibrium of a costless barter economy the same result holds in a one sided peg if the pegging country s exchange rate stabilizing authority breaks even over time in a cooperative peg regime there is a different equilibrium allocation for each combination of exchange rate levels and monetary policies problems of policy coordination and conflicts in desired monetary policies are discussed

how to split the pie optimal rewards in dynamic multi battle competitions abstract multi battle competitions are ubiquitous in real life in this paper we examine the effort maximizing reward design in sequentially played multi battle competitions between two players the organizer has a fixed prize budget and rewards players contingent on the number of battles they win in a three battle contest a full spectrum of contest technologies in the tullock family is accommodated we find that the optimal design varies with the discriminatory power of the contest technology in particular when it is in the low range winner take all is optimal for the intermediate range as discriminatory power increases the optimal prize structure evolves continuously from winner take all to the proportional division rule due to the need to mitigate the growing momentum discouragement effect for the high range a wide span of prize structures extracts full surplus and is thus optimal several robustness checks confirm that mitigating the momentum discouragement effect is essential for effort maximizing prize design in dynamic multi battle contests

capital market imperfections and the theory of optimum currency areas this paper studies how within and cross country capital market imperfections affect the welfare effects of forming a currency union the analysis considers a bank only world where intermediaries compete in cournot fashion and monitoring and state verification are costly the first part determines the credit market equilibrium and the optimal number of banks prior to joining the union the second part discusses the benefits from joining a currency union a competition effect is identified and related to the added monitoring costs that banks may incur when operating outside their home country through an argument akin to the brander krugman reciprocal dumping model of bilateral trade however in our framework whether joining a union raises welfare of the home country is ambiguous it depends on the relative strength of investment creation and intermediation diversion effects

capital controls and the real exchange rate capital import taxes lower raise world home interest rates this shifts home expenditure from the present to the future and foreign expenditure from the future to today with identical home and foreign expenditure patterns the change in the composition of world expenditure has no effects on demand for any commodity then capital controls have no effect on the real exchange rate when consumers prefer home goods capital controls cause lower demand today for home goods in this way capital controls lower the real exchange rate today this result is mitigated when the country imposing capital controls is a large debtor

money bonds and foreign exchange in the theory of finance capital markets provide securities which allow the ownership of productive assets to be allocated among investors according to their willingness to bear risk in exchange for return and independently of their tastes for the productive services provided by the assets this paper uses the theory of finance to study the role of money as a productive asset and the transformation of money into a portfolio asset true to its purpose the capital market provides securities nominal bonds that allow an allocation of the current services of the money supply according to its current productivity and without regard for its future purchasing power risk and an allocation of the future purchasing power risk of the money supply according to the willingness of investors to bear this risk in exchange for return and without regard for investor needs for the future transactions services of money in open

real exchange rates and macroeconomics a selective survey the paper discusses real exchange rate issues of industrial and of developing countries for real exchange rates among the key industrial countries we ask what is the best conceptual framework to shed light on this question we look at alternative theoretical approaches and at empirical evidence on the relation among interest rates expectations and depreciation the discussion of developing countries real exchange rates focuses on the link between real exchange rates real wages and the profitability of capital the model highlights the discrepancy between the mobility of capital including in the long run physical capital and

did the ems reduce the cost of capital we propose a dynamic arbitrage pricing theory apt multi factor model with time varying volatility for currency bond and stock returns for ten european countries over 1977 97 we exploit the cross sectional dimension of the model to construct world portfolios which when added to the original list of assets allow us to develop simple consistent methods of estimation and testing our results reject the implicit asset pricing restrictions and suggest decreases in idiosyncratic exchange rate risk tend to lower the cost of capital although the effect is small we assess the potential gains from increased stock market integration

an investigation in the theory of foreign exchange controls a choice theoretic cash in advance model is constructed to examine foreign exchange controls while foreign exchange controls improve the trade balance and the balance of payments or exchange rate they reduce welfare for a distortion free small open economy this is because foreign exchange controls essentially place a quota on imports shocks to the terms of trade are shown to be transmitted negatively to the domestic economy when exchange controls are in effect devaluations are found not to have real effects finally it is argued that foreign exchange controls are not the optimal policy for attaining trade balance objectives

fiscal policy and the current account deficits and trade jose vinals does the balance of payments act as an external constraint on the design of domestic economic policy in practice most governments believe it does yet popular discussion is sometimes confused this paper begins by evaluating the nature of the external constraint and the extent to which it can adequately be measured by the current account of the balance of payments it is often argued that a fiscal expansion will increase employment it is also widely held that a fiscal expansion necessarily leads to a deterioration of the current account while these propositions may hold in specific circumstances neither is generally true the theoretical basis of the two propositions is examined and compared with recent international experience when important changes in fiscal stance occurred the popular presumptions are confirmed by recent experience in the us the uk and germany but france is a counterexample to the first and spain to the second the important policy implication is that one can identify both in theory and in practice clear circumstances in which expansionary fiscal policy is appropriate and will not be thwarted by external considerations

dual exchange rate systems and capital controls an investigation abstract the welfare aspects of dual exchange rate systems are analyzed in this paper the requirement that domestic financial transactions with the rest of the world be undertaken at a special foreign exchange rate is found to be equivalent to levying a tariff on this class of international transactions hence a dual exchange rate system and capital controls are shown to be essentially identical in light of the above statements the dual exchange rate system should be regarded as a form of commercial policy and be evaluated in this context by applying the applicable standard real trade theorems

the real exchange rate the capital stock and fiscal policy abstract this paper studies the joint determination of aggregate supply the real exchange rate and the current account in response to changes in government spending in a model where there is no uncertainty in the aggregate but where individuals are uncertain about their lives duration international capital mobility fixes the steady state capital stock and aggregate supply in a small country whereas in a large country the steady state capital stock is endogenous an increase in government spending is more likely to generate a real exchange rate depreciation in a small country since the loss of wealth associated with cumulated current account deficits does not increase rest of the world spending in the case of a large country current account deficits are wealth transfers to the rest of the world and increase foreign spending thus the normal long run response is an increase in the relative price of domestic output

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

budget deficits and the current account an intertemporal disequilibrium approach the objective of the present paper is to develop an intertemporal disequilibrium model of a monetary economy to explain the effects of fiscal policy on the current account we wish to emphasize the role of aggregate demand determined output fluctuations and flexible exchange rates within a microtheoretic optimizing framework furthermore the differing effects of monetary versus non monetary i e tax or bond finance of government expenditures are considered

useful government spending direct crowding out and fiscal policy interdependence this paper introduces perfect substitutability between private and public consumption in a dynamic open economy with imperfect competition and nominal rigidities this implies a direct crowding out effect that generalising to the two country case some well known properties of a closed economy tends to reduce consumption following both domestic and foreign expansions a less expected result is that sub stitutability has a positive effect on the short run output spillover we also show that if we modify the model to allow for home bias in government spending temporary fiscal expansions display a quasi neutrality property

an equilibrium model of exchange rate determination and asset pricing with nontraded goods and imperfect information this paper presents a two country model with maximizing households stochastic production stochastic money growth and perfect capital mobility because of the presence of nontraded goods households in different countries consume different goods analytic solutions are presented for the nominal exchange rate the real exchange rate nominal interest rates and real interest rates it is shown that the model is compatible with some important features of the real world behavior of exchange rates when households are imperfectly informed about the distribution of money growth the exchange rate exhibits patterns of overshooting and is more volatile than the ratio of the money stocks copyright 1987 by university of chicago press

trade in nominal assets and net international capital flows abstract nominal assets play a major role in international financial markets while trade in indexed bonds is limited as a result agents are exposed to both price and exchange rate uncertainty nonetheless previous research on net capital flows has assumed the presence of a risk free vehicle to intertemporal asset trade in this paper we develop a general equilibrium intertemporal model with trade limited to nominal bonds and equity we find that exposure to nominal risk dampens net capital flows thus making economies effectively more closed

liquidity exchange rates and business cycles abstract this paper presents a two country two good two currency model to study the role of liquidity effects in exchange rate determination and the international transmission of economic fluctuations the model provides an exchange rate equation which is different from the simple purchasing powerparity law of exchange rate determination both monetary injections and real disturbances can lead to exchange rate fluctuations and comovements of interest rates prices and output of the two economies whether the covariances of variables in the two countries are positive negative or zero depends critically upon the substitutability of the two consumption goods in consumers preferences

on the effectiveness of capital controls the experience of colombia during the 1990s abstract this paper analyzes the effectiveness of capital controls in colombia the evidence presented points towards a relative inability of the measures adopted to reduce the level of capital inflows nonetheless the evidence suggests that non remunerated deposits have been successful in inducing a recomposition of foreign liabilities in favor of long term maturities it is likely that this is a positive result as it has made the country less vulnerable to a reversal in capital flows in this sense controls may be viewed as an effective way of internalizing the negative externality imposed by short term maturities

intertemporal optimizing models of trade and current account balance a survey abstract this study surveys the intertemporal optimizing models of trade and current account balance that were developed calibrated and empirically tested since they came into vogue in the 1980s the implications of these models often differ from those of static and dynamic conventional non optimizing models the literature on optimizing models has not only grown reasonably fast but has also witnessed significant advances in methodology and these models have culminated into a distinct strand of new open economy macroeconomics the studies conducted until the late 1980s have used deterministic perfect foresight models while several studies conducted since the 1990s relax the perfect foresight and certainty equivalence assumptions and develop stochastic dynamic general equilibrium models to account for uncertainty confronting the optimizing agents the future research needs to explore the possibility of tracing any preferred specification of household preferences model the effect of time varying discount factor on household utility function and intertemporal budget constraint examine the role of costs in international trade place a parallel emphasis on the empirical verifications of theoretical propositions examine the relative performance of optimizing vis a vis non optimizing models and rationalize the extreme propositions of perfect and imperfect capital mobility in the wake of moderately open capital accounts

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

the optimal allocation of prizes in contests we study a contest with multiple not necessarily equal prizes contestants have private information about an ability parameter that affects their costs of bidding the contestant with the highest bid wins the first prize the contestant with the second highest bid wins the second prize and so on until all the prizes are allocated all contestants incur their respective costs of bidding the contest s designer maximizes the expected sum of bids our main results are 1 we display bidding equlibria for any number of contestants having linear convex or concave cost functions and for any distribution of abilities 2 if the cost functions are linear or concave then no matter what the distribution of abilities is it is optimal for the designer to allocate the entire prize sum to a single first prize 3 we give a necessary and sufficient conditions ensuring that several prizes are optimal if contestants have a convex cost function

international asset pricing with time varying risk premia abstract recent empirical evidence that forward exchange rates are biased predictors of future spot rates can also be interpreted as evidence against the hypothesis of a constant risk premium consequently reconciliation of this evidence with efficient international capital markets requires the existence of time varying risk premia this paper modifies kouri s 1977 asset pricing model to allow time varying exected returns on assets eliminates the assumption of a risk free real asset and derives the characteristics of the risk premia in the forward market as well as the equilibrium yield relationships among the equities and riskless nominal bonds of all countries

foreign exchange controls in a black market economy abstract an investigation of the impact of foreign exchange controls in a black market economy is undertaken within the context of a choice theoretic cash in advance general equilibrium model while such controls may improve a distortion free economy s trade balance and balance of payments they are found to increase the domestic price of imports and lower the country s welfare the ramifications of black market for economic welfare turn out to be ambiguous depending crucially on the government s reaction to the leakage of foreign exchange into the economy via illegal activity

equilibrium valuation of foreign exchange claims this article studies the equilibrium valuation of foreign exchange contingent claims within a continuous time lucas 1982 two country model exchange rates interest rates and in particular factor risk prices are all endogenously and jointly determined this guarantees the internal consistency of these price processes with a general equilibrium in the same model closed form valuation formulas are presented for currency options and currency futures options common to these formulas is that stochastic volatility and stochastic interest rates are admitted hedge ratios and other comparative statics are also provided analytically it is shown that most existing currency option models are included as special cases this article studies the equilibrium valuation and hedging of foreign exchange contingent claims the framework for analysis is the continuous time counterpart of the well known two country monetary model of lucas 1982 1 that is we use the modeling structure of lucas 1982 and adopt his representativeagent perfect pooling equilibrium notion rather than extending the lucas setup to a cox ingersoll and ross 1985a henceforth cir production economy as is done in nielsen and saa requejo 1993 for our purpose the lucas framework offers the desired simplicity and tractability we assume a stochastic structure for the international economy such that the resulting nominal interest rates and exchange rate dynamics exhibit similar empirically plausible features as the corresponding ones in nielsen and saa requejo 1993 for example the endogenous interest rates are positively correlated across national borders campbell and clarida 1987 and ilmanen 1995 as a predictor of future spot exchange rates the equilibrium forward exchange rate is biased in a direction consistent with the forward premium puzzle

money and asset prices in a cash in advance economy an asset pricing model with money introduced via a cash in advance constraint is presented the monetary velocity is variable hence money demand does not obey the trivial quantity equation the effects of disturbances in output and money growth on real balances the price level and interest rates are examined monetary policy has effects on real asset prices the fisher relation and the premium on nominal bonds are discussed the precise role of the timing of information and transactions for properties of price levels and interest rates are clarified

multi battle contests abstract we study equilibrium in a multistage race in which players compete in a sequence of simultaneous move component contests players may win a prize for winning each component contest as well as a prize for winning the overall race each component contest is an all pay auction with complete information we characterize the unique subgame perfect equilibrium analytically and demonstrate that it exhibits endogenous uncertainty even a large lead by one player does not fully discourage the other player and each feasible state is reached with positive probability in equilibrium pervasiveness expected effort in the component contests may be non monotonic in the closeness of the race and realized individual effort may exceed the value of the prize by a factor that is proportional to the maximum number of stage victories required

currency composition of international bonds the emu effect abstract we analyze the impact that the launch of the emu had on the currency denomination of private international bond issues in 1990 2006 using micro level data our stylized model predicts that the introduction of the euro would lead to an increase in the share of euro denominated debt and a decline in the share of dollar denominated debt issued by firms located in countries outside both the united states and the euro area moreover our model predicts that the euro effect would be particularly pronounced for nonfinancial firms our empirical results are consistent with these predictions in addition we find that among nonfinancial firms the impact on new issuers is larger than on seasoned issuers extending the model to allow for differences in issuance volumes across future monetary union countries prior to integration we also predict larger increases in euro denominated issuance among firms from smaller monetary union countries we confirm this prediction for international bond issues by euro area firms

industrial structure in the eurocredit underwriting market abstract while the complexity of underwriting syndicates is well known there has been very little empirical analysis of syndicate structure the short term eurocredit market is a promising market for the analysis of industrial structure because underwriting syndicates generally come in a two tier structure the structures of syndicates in this market are analyzed here empirically our evidence suggests that the lead managers in these syndicates seem to be recruited primarily for paycosts of risk bearing and sharing while the regular managers appear to be recruited primarily for the purpose of dealing with expanded underwriting distribution risks held constant contract parameters that affect syndicate size and structure are examined in detail for various instruments

mode locking and international business cycle transmission abstract we investigate international business cycle synchronization business cycles in many countries have a tendency to synchronize with one another in what appears to be a world business cycle yet researchers find that trade and capital linkages are not strong enough for one country to drive business cycles in another country how is this world business cycle formed this study suggests that the world business cycle results from a mode locking phenomenon a nonlinear process by which weak coupling between oscillating systems tends to synchronize oscillations in the systems simulations and econometric analyses are performed to attempt to verify this hypothesis

in defense of the finance constraint simple models of monetary trade commonly impose a finance constraint on expenditure it is often suggested that this finance constraint is artificial a result of money s being the only asset of the absence of credit and of the special time structure of such models this paper shows that the finance constraint on aggregate expenditure remains in force when other assets and credit are introduced and when the time structure is generalized to allow overlapping income periods of differing lengths most of the objections to the finance constraint are shown to involve fallacies of composition there are economists to whom a constraint of the form pc m in units t must appear unthinkable r e lucas jr 1980

monetary growth innovations in a simple cash in advance asset pricing model abstract this paper contributes to the existing literature in the rational expectations cash in advance asset pricing general equilibrium model in two directions first we show that by allowing a variable velocity of circulation an increase in the conditional variance of the money growth process triggers an increase in the demand for money relative to stocks and bonds with a consequent reduction in stock and bond prices which is the opposite of the current result in the literature with constant unitary velocity second we explicitly show how the sequential markets and specific timing of information fits exactly into the notion of irreversibility in the sense that when faced with uncertainty agents might find optimal to delay decisions in order to wait for the arrival of new information

sticky goods prices flexible asset prices monopolistic competition and monetary policy a monetary general equilibrium asset pricing model with sticky goods prices is developed goods prices are set by monopolistically competitive firms that maximize stock market value equilibria with underutilization of resources excess capacity in some states result in contrast to previous monetary asset pricing models the degree of competition affects capacity utilization monetary policy can affect output and resource utilization in addition to real asset prices depending upon the amount of information available to the monetary authority

the role of saving and investment in exchange rate determination under alternative monetary mechanisms abstract we argue that the demand for national currencies depends on existing payment arrangements for imports and exports therefore exchange rate movements depend on these arrangement as a result the relationship between exchange rate movements and various macroeconomic aggregates like saving and investment depend on what we call the monetary mechanism these points are explicitly demonstrated by studying two extreme monetary mechanisms one in which all payments are done with the seller s currency and one in which all payments are done with the buyer s currency

orchestrating rent seeking contests contests have different sometimes quite complex organisational structures in particular while most of the existing literature focusses on simultaneous contests multistage contests are also quite frequently encountered this paper seeks to provide a rationale for the latter by endogenising the choice of a contest structure which is made by an organiser of a contest interested in maximising the efforts expended by the contenders

exchange rates and traded goods prices abstract this paper presents a partial equilibrium model of the determination of domestic and export prices by a monopolistic competitive firm the model stresses the role of exchange rate uncertainty and expectations the most important result of the analysis is that the stochastic properties of deviations from the law of one price are crucially affected by the currency of denomination of export prices using data on domestic and dollar export prices of japanese goods i find that deviations from the law of one price are due to exchange rate surprises but also to price staggering and ex ante price discrimination

market standards in financial contracting the euro s effect on debt securities abstract the introduction of the euro ushered in a rise to dominance of english contract law in european debt securities corporate issuers in the euro zone chose english law significantly more often than a control group from other european countries the euro effect on choice of law is particularly strong for debt securities in local markets that arguably were most affected by the euro the euro effect is not explained by differences in the suitability of english law compared to other laws a change in issuer composition or debt securities types and the greater market share of british and american underwriters we argue that increased standardization benefits network effects from a boost in cross border investment provide the best account of why english law conquered the european debt securities market

capital controls and fiscal policy in the world economy an intertemporal utility maximization framework is employed to model a world economy with capital controls the effects of fiscal policy in such an environment are examined several results emerge concerning the international transmission of fiscal policy under capital controls and the nature of comovements in macro economic aggregates such as output employment consumption and investment some of the paper s other results concern the implications of capital controls for ricardian equivalence the role of financing decisions in the international transmission process under capital controls and the effect of capital controls on the magnitude of fiscal induced fluctuations throughout the world economy contr6les des mouvements de capitaux et politique fiscale dans l conomie mondiale les auteurs utilisent une approche par la maximisation intertemporelle de l utilite pour modeliser une economie mondiale dans laquelle des controles sur les mouvements de capitaux existent ils examinent les effets de la politique fiscale dans un tel contexte on tire de ces analyses plusieurs resultats quant i la transmission internationale des effets de la politique fiscale et quant aux mouvements lies de certains agregats economiques comme les niveaux de production d emploi de consommation et d investissement certains autres resultats de cette analyse ont trait aux implications des controles des mouvements de capitaux sur l1 quivalence ricardienne au role des decisions de financement dans le processus international de transmission quand il y a controle des mouvements de capitaux et aux effets des controles sur les mouvements de capitaux sur la magnitude des fluctuations induites a travers l economie mondiale par la politique fiscale helpful comments from two anonymous referees are gratefully acknowledged discussion in workshops held at ucla duke university iowa state university queen s university vanderbilt university vpi and the university of western ontario has also been useful canadian journal of economics revue canadienine d economique xviii no 4 november novembre 1985 printed in canada imprime au canada 0008 4085 85 743 65 1 50 canadian economics association this content downloaded from 207 46 13 129 on mon 27 jun 2016 05 25 03 utc all use subject to http about jstor org terms 744 jeremy greenwood and kent p kimbrough

understanding the dynamic effects of government spending on foreign trade abstract using vector autoregressions on u s time series the present paper documents the effects of fiscal policy on foreign trade an increase in government spending significantly depreciates the nominal exchange rate appreciates the terms of trade and increases net exports exposed to the same spending shock a new keynesian general equilibrium model is shown to match qualitatively the response of relative prices the response of net exports in contrast depends on the intra and intertemporal elasticities of substitution and the degree of home bias in private spending an accommodating monetary policy dampens but does not alter the response of net exports

global effects of national stabilization policies under fixed and floating exchange rates this paper deals with international effects of two types of stabilization policies monetary expansion directed towards the demand side and a reduction in payroll taxes directed towards the supply side the analysis focuses on employment relative prices and welfare issues it rests on a simple intertemporal general equilibrium model of two countries that includes a specific micro theory of money under floating exchange rates a country s employment is insulated from both policies abroad but its consumption generally changes under fixed exchange rates no such insulation prevails while monetary expansion is generally expansionary reduced payroll taxes constitute a beggar thy neighbor policy in both systems the welfare of a country may decrease although its employment increases an immiserizing expansion may occur

the current account and the optimal government debt abstract in this paper we analyze the optimal response of the current account and the government debt to real disturbances permanent and temporary lumpsum taxes are not feasible and the government income is raised according to the ramsey rule for optimum taxation we show that permanent disturbances have no effects on either the private or the government current account if initially there are no deficits starting off from the same initial situation both the private sector and the government develop a deficit on current account in response to a temporary disturbance

real transfers in fixed exchange rate systems and the international adjustment mechanism abstract fixed exchange rates can be maintained by different types of stabilization schemes this paper takes a look at some alternative institutional settings and shows that there is an inherent redistribution mechanism in some of them that will influence the world allocation of consumption an examination of the global adjustment to monetary disturbances illustrates some interesting implications of the institutional differences between alternative systems the results suggest that the description of the international adjustment mechanism under fixed exchange rates given by the monetary approach to the balance of payments is valid only under quite restrictive assumptions

excess capacity monopolistic competition and international transmission of monetary disturbances analyzes the excess capacity monopolistic competition and international transmission of monetary policy disturbances in the united states sheds light on the international impact of monetary policy emphasis on the spillover effects of monetary disturbances similarity of framework used with open economy macroeconomics

trade in nominal assets monetary policy and price level and exchange rate risk in a previous paper trade in risky assets i have analyzed the pattern of international trade in risky real assets between barter economies relying on the law of comparative advantage and using autarky asset price differences to predict the pattern of asset trade in this paper the analysis is extended to international trade in nominal assets assets with returns paid in currencies between monetary economies the risk chracteristics of real returns on nominal assets depend on price level and exchange rate risk and therefore on monetary policy it is examined how different combinations of monetary policies and exchange rate regimes affect nominal assets return risk characteristics their autarky perices and hence their trade pattern when countries differ with respect to their outputs or their attitudes towards risk when world asset markets are incomplete different monetary policies and exchange rate regimes have dramatic effects on risk characteristics of home and foreign currency bonds and on the trade pattern in these assets as well as on aggregate capital and current accounts

inflation and welfare in the steady state this is a paper on expected inflation and welfare in steady state equilibrium the demand for money is an inventory demand with an endogenous payment period the clower constraint is not imposed higher inflation reduces welfare by reducing consumption as people devote more of their real income to maintaining lower average money holdings high inflation does not necessarily promote an increase in the capital stock the mundell tobin effect is absent the policy conclusion is standard deflate at the rate of time preference because capital is held socially optimal consumption falls short of its golden rule level if inside money is allowed it drives out fiat money and welfare is again at a maximum

dynamics of a floating exchange rate regime we study the full equilibrium dynamics of a two country world economy with a floating exchange rate traded and nontraded goods and explicit modeling of the use of money the resulting exchange rate equation depends on several details of the economic structure such as the supply structure and propensities to spend on various goods although real exchange rate movements have the usual association with the current account the ordinary exchange rate may appreciate or depreciate when there are deficits on current account even when the quantities of money do not change deviations from purchasing power parity and the fisher equation are shown to be the rule rather than the exception

incentives versus competitive balance abstract when players compete repeatedly prizes won in earlier contests may improve the players abilities in later contests this paper determines the allocation of prizes within and across contests that maximizes the weighted sum of aggregate efforts

moral hazard in repeated procurement of services this paper analyzes repeated procurement of services as a two period model with a potential repeated agency relationship in the first period there is an incumbent who provides a service in the second period there is a contest stage in which the principal selects the next service provider the agents effort is non contractible and the contest stage is the mechanism to mitigate potential moral hazard problems the principal takes account of the past service effort in the contest stage by choosing the weight of past effort and the degree of substitutability between past and current efforts the results show that when the principal does not value contest effort considering past effort as the relevant effort in the contest is optimal when the principal values contest effort and effort cost increases decreasing substitutability between efforts is optimal

currency preferences purchasing power risks and the determination of exchange rates in an optimizing model most recent research on the theory of exchange rate determination treats the exchange rate as the relative price of two assets domestic money and foreign money the value of an asset depends on the distribution of its return however most of the research has dealt with models in which there is no uncertainty the present paper focuses on questions that cannot be addressed in a world of certainty because in such a world an asset is never risky it investigates how purchasing power risks affect the determination of exchange rates this investigation is pursued in a fairly general optimizing model the present research is related to some recent work in international economics and in financial economics it follows the approach of obstfeld 1981 and stockman 1980 in that it uses an optimizing model and takes into account the role of government transfers in the flow budget constraint of individuals as in calvo and rodriguez 1977 stockman 1980 and others the fact that holdings of foreign monies are useful to domestic individuals is taken into account finally the paper uses techniques developed in papers in the finance literature which build on merton s 1973 asset pricing model and use a concept of equilibrium developed in

capital controls and international trade finance abstract this paper studies the effects of prohibiting individuals from holding foreign assets but of allowing firms to trade in foreign assets only up to what is needed to finance export and import activities although firms can perform arbitrage between domestic and foreign financial markets the distortions in asset markets are not fully arbitraged away but instead are transmitted to domestic goods markets the dynamics and steady state responses to a variety of shocks are crucially affected by capital controls even in the presence of capital controls the volatility of domestic interest rates can be substantial

channels of international policy transmission abstract four channels of international budgetary and monetary policy transmission are analysed within the context of nominal wage sluggishness the first is based on capital gains on holdings of foreign assets spill over effects arising through the second and third channels depend on whether home and foreign goods are gross substitutes or gross complements and on whether the elasticity of intertemporal substitution is less or greater than one the final channel assumes finite lifetimes and no bequest motive it departs from debt neutrality in order to give a non trivial role to wealth effects and current account dynamics

exposure and markups this article examines how to properly specify and test for factors that affect exchange rate exposure starting from theoretical underpinnings and a sample of u s manufacturing industries between 1979 and 1995 we find that 4 of 18 industry groups are significantly exposed to exchange rate movements through the effect of industry competitive structure export share and imported input share on average a 1 appreciation of the dollar decreases the return of the average industry by 0 13 consistent with our model s predictions as an industry s markups fall rise its exchange rate exposure increases decreases exchange rate movements are an important source of risk for a firm they affect a firm s expected cash flows and or change the terms of competition for exporters importers and multinationals hung 1992 estimates that during the 1980s u s manufacturing industries lost approximately 23 billion year or 10 of total profits due to the dollar s movements surprisingly early studies which assume exchange rate exposure to be constant e g jorion 1990 bodnar and gentry 1993 and amihud 1994 find that exchange rates have no effect on the stock returns of u s multinationals exporters or manufacturing industries recently however allayannis 1997 and bodnar dumas and marston 1998 examine time varying exposure of industry returns 1 in particular the former article focuses on the effect the variation of u s industries import and export shares have on exposure while the latter focuses on pass through and exposure in a sample of japanese export oriented industries besides trade shares and pass through exchange rate exposure also depends on the markup of an industry specifically in industries with

liquidity constraints and the formation of unbalanced contests abstract we analyze the effects of future liquidity constraints on contestants investment in a dynamic contest model contestants invest in two consecutive contests to win a prize in each period the loser of the first period contest can be liquidity constrained in the second period due to too little remaining wealth the winner of the first contest can reinvest the prize in the second contest we show that future liquidity constraints mainly affect the imbalance of the contest in the future but not today surprisingly larger contest prizes decrease contestants future investments and amplify the imbalance of future contests however the contest organizer can reduce this imbalance by increasing the share of the prize money in the second contest

the international ramifications of tax reforms supply side economics in a global economy this paper studies tax reforms in a dynamic model of a global economy calibrated to current u s and european tax policies world capital markets add consumption smoothing and income redistribution effects that alter closed economy predictions in the absence of taxes on foreign interest welfare gains of eliminating u s income taxes are enlarged by up to 34 percent at the expense of european losses caused by transitional declines in consumption and leisure and a permanent capital outflow in contrast if foreign interest is taxed the same tax reform reduces u s welfare 0 7 percent and increases european welfare 1 8 percent copyright 1998 by american economic association
