explaining the border effect the role of exchange rate variability shipping costs and geography this paper exploits a three dimensional panel data set of prices on 27 traded goods over 88 quarters across 96 cities in the us and japan we show that a simple average of good level real exchange rates tracks the nominal exchange rate well suggesting strong evidence of sticky prices focusing on dispersion in prices between city pairs we find that crossing the us japan border is equivalent to adding as much as 43 000 trillion miles to the cross country volatility of relative prices we turn next to economic explanations for this so called border effect and to its dynamics distance unit shipping costs and exchange rate variability collectively explain a substantial portion of the observed international market segmentation relative wage variability on the other hand has little independent impact on segmentation 2001 elsevier science b v all rights reserved

real exchange rates and relative prices an empirical investigation abstract this paper uncovers a striking empirical regularity the consumer price of a good relative to a different good within a country tends to be much less variable than the price of that good relative to a similar good in another country this fact seems to hold for all goods except very simple homogeneous products models of real exchange rates are likely to have predictions regarding this relation so this fact may provide a useful gauge for discriminating among models

wages relative prices and the choice between fixed and flexible exchange rates this paper reexamines the choice between fixed and flexible exchange rates to take into account wage indexation and flexible prices the difference in output variation in the two exchange rate regimes is shown to be dependent on wage behaviour in the domestic economy being proportional to one minus the degree of wage indexation foreign wage behaviour is also shown to be of key importance since high wage indexation abroad can insulate the domestic country from some foreign disturbances regardless of domestic behaviour while for other economic disturbances it is the relative degree of wage indexation which determines the desirability of flexible rates niveaux de salaires prix relatifs et le choix entre les regimes de taux de change fixes ouflucttuants ce memoire reouvre le dossier du choix entre regime de taux de change fixes et regime de taux de change fluctuants quand on tient compte de l indexation des salaires et de la flexibilite des prix il appert que l ecart entre les variations du niveau de production domestique entre les deux regimes depend du comportement des salaires dans l economie domestique il est proportionnel a 1 le degre d indexation des salaires le comportement des salaires dans le reste du monde est aussi important puisque un haut degre d indexation des salaires dans le reste du monde peut proteger l economie domestique de certaines perturbations economiques h l etranger quel que soit le comportement des salaires domestiques dans le cas d autres perturbations economiques c est le degre relatif d indexation des salaires h l interieur et h l exterieur qui devient le facteur determinant dans le choix d un regime de taux de change how much difference a flexible exchange rate makes to the economic performance of a country depends significantly on wage behaviour if wages are sufficiently sensitive to exchange rates output will exhibit much the same variability under flexible exchange rates as under fixed rates foreign wage behaviour is also of key importance since high wage flexibility abroad can insulate the domestic country from some foreign disturbances regardless of domestic wage behaviour while for other economic disturbances it is the relative degree of wage flexibility which determines the desirability of flexible rates this paper re examines the choice between fixed and flexible rates taking into account both domestic and foreign wage

capital markets and the exchange rate with special reference to the dollarization debate in latin america the paper reviews the main challenges faced by policymakers in emerging market economies em in light of recent financial crises and taking into account salient factors like the existence of partial dollarization imperfect credibility weak financial systems and contagion the standard theory of optimal currency areas is discussed and criticized for omitting the above factors when these factors are taken into account an extreme foreign exchange regime like dollarization is shown to become much more attractive the paper discusses the pros and cons of dollarization and among other things shows that the lack of a lender of last resort is not necessarily a major drawback in em the paper also discusses inflation targeting it in a formal model it is shown that it could be subject to credibility problems similar to those found in exchange rate based stabilization programs

money interest rates and exchange rates with endogenously segmented markets we analyze the effects of money injections on interest rates and exchange rates when agents must pay a baumol tobin style fixed cost to exchange bonds and money asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money infrequently when the government injects money through an open market operation only those agents that are currently trading absorb these injections through their impact on these agents consumption these money injections affect real interest rates and real exchange rates the model generates the observed negative relation between expected inflation and real interest rates as well as persistent liquidity effects in interest rates and volatile and persistent exchange rates

asean income gap and the optimal exchange rate regime this article investigates the optimal exchange rate regime in a group of asean countries which minimizes the adverse effects of foreign demand shocks on real output the real exchange rate price

potential pitfalls for the purchasing power parity puzzle sampling and specification biases in mean reversion tests of the law of one price the ppp puzzle is based on empirical evidence that international price differences for individual goods loop or baskets of goods ppp appear highly persistent or even nonstationary the present consensus is these price differences have a half life that is of the order of five years at best and infinity at worst this seems unreasonable in a world where transportation and transaction costs appear so low as to encourage arbitrage and the convergence of price gaps over much shorter horizons typically days or weeks however current empirics rely on a particular choice of methodology involving i relatively low frequency monthly quarterly or annual data and ii a linear model specification in fact these methodological choices are not innocent and they can be shown to bias analysis towards findings of slow convergence and a random walk intuitively if we suspect that the actual adjustment horizon is of the order of days then monthly and annual data cannot be expected to reveal it if we suspect arbitrage costs are high enough to produce a substantial band of inaction then a linear model will fail to support convergence if the process spends considerable time random walking in that band thus when testing for ppp or loop model specification and data sampling should not proceed without consideration of the actual institutional context and logistical framework of markets

optimal wage re negotiation in a closed and open economy abstract this paper investigates an economy in which there are short term wage contracts that are re negotiated under certain conditions the paper determines the optimal frequency of wage re negotiation and shows that it depends positively on measures of aggregate variability and phillips curve slope the role of optimal wage re negotiation is to mitigate the output effects of various shocks in the context of an open economy it is shown that the desirable exchange rate regime in an economy with optimal wage re negotiation depends on the stochastic structure of the economy

a note on dual foreign exchange markets with official rationing predetermined versus floating official exchange rate abstract this paper examines the relationship between the long run rate of inflation and the allocation of transactions between markets in economies that operate dual exchange market regimes and ration foreign exchange in the official market it shows that wider access of importers to the official market and wider access of exporters to the free market are associated with higher rates of inflation and vice versa the direction of causality among the various variables and thus the effects of economic policies depend on whether the official exchange rate is predetermined or floating

open economy macro policies and the micro foundation of labor market arrangements abstract in this paper we assume that risk neutral firms provide income insurance to risk averse workers through labor contracts however because of ad hoc transaction costs contracts are not fully contingent hence while contracts improve upon the allocation of risk they entail ex post production inefficiencies relative to a spot market where employment decisions are based upon realizes values of productivity shocks given this tradeoff there exists the possibility that both labor markets can coexist in equilibrium we analyze the effects of exchange rate policy on the distribution of agents across labor market arrangements and the expected utility of agents

migration and income redistribution responsibilities this study examines whether afdc benefits determine or discourage state to state migration flows in the united states a pooled cross section time series model is developed to estimate afdc benefits in a state and recipients and whether benefits in one state affect benefits in other states a second model using data from the 1980 census and the panel study of income dynamics estimates migration of afdc recipients and the level of benefits in in migration and out migration states both models indicate that small but statistically significant amounts of migration occur which may be quite important but only in the long run movers although small in number are much more likely to move to a state with higher benefits states perceive this migration as important indicating that states should have less control and the federal government more control over income redistribution

an examination of the effects of government purchases in an open economy this paper examines the effects of permanent and transitory changes in government purchases in the context of a model of a small open economy that produces and consumes both traded and nontraded goods the model incorporates an equilibrium interpretation of the business cycle that emphasizes the responsiveness of agents to intertemporal relative price changes it is demonstrated that transitory increases in government purchases lead to an appreciation of the real exchange rate and an ambiguous change although a likely worsening in the current account while permanent increases have an ambiguous impact on the real exchange rate and no effect on the current account when agents do not know whether a given increase in government purchases is permanent or transitory the effect is a weighted average of these separate effects the weights depend on the relative variances of the transitory and permanent components of government purchases in the past few years a considerable amount of effort has been devoted to examining the effects of macroeconomic policy in an open economy such issues as exchange rate overshooting deviations from purchasing power parity sterilization and monetary control the effectiveness of monetary policy and the choice between alternative exchange rate regimes have been at center stage the models that have been employed to study these issues have run the spectrum from variants of the mundell fleming model such as dornbusch 1976 turnovsky 1981 and kimbrough 1983a to wage contracting and indexing models like bhandari 1982b and flood and marion 1982 to equilibrium models of the business cycle along the lines of bhandari 1982a saidi 1982 and kimbrough 1983b to the closely related intertemporal utility maximization models with money of helpman 1981 and stockman 1980 1983 one common thread that in a sense unifies all of these and other recent contributions is that they are concerned primarily with the effects of alternative monetary and exchange rate policies that the central bank might enact in light of the development and refinement during this period of the monetary approach to the balance of payments and the exchange rate it is not surprising i would like to thank phil brock jeremy greenwood gary zarkin and two anonymous

aggregate information and the role of monetary policy in an open economy a model of a small open economy in which agents trade in local goods markets and an economy wide asset market is developed purchasing power parity is assumed to hold at the aggregate level however because of local deviations from purchasing power parity agents possess differential information using this framework it is shown that when the exchange rate is flexible monetary policy can influence the distribution of real output by altering the information content of the exchange rate however when monetary policy is committed to fixing the exchange rate by a feedback rule the distribution of real output is independent of the particular exchange rate rule chosen the stability of real output under the two regimes is compared and it is demonstrated that regardless of the stability of domestic monetary policy a flexible exchange rate regime is superior in this respect possible qualifications and extensions of these results are also discussed

the effect of welfare and wage levels on the location decisions of female headed households abstract this paper develops and estimates a model designed to calculate the impact of welfare benefit levels wages and tax rates on the location choices of female headed households the empirical model assumes that women simultaneously choose both where they will live and whether or not they will participate in the welfare system based on their expected income and expected hours of work for each location participation possibility these income and hours expectations depend in turn on the welfare benefits wage and tax rates facing each household in each location it is found that both regional welfare levels and wage rates have a significant effect on the location decisions of this population the probability of a typical female headed household with little outside income leaving an area with low welfare payments and low wages can be as much as 12 points higher over a 4 year period than the probability of leaving a high welfare high wage area

the information content of the exchange rate and the stability of real output under alternative exchange rate regimes abstract when the exchange rate is flexible and thus responds to market forces it provides agents with useful information while when it is fixed by a feedback rule it does not the implications of this asymmetry for the stability of real output under the two regimes is discussed it is shown that whenever shocks are predominantly of one variety or when domestic monetary shocks accompanied by one real shock a flexible exchange rate does a better job of stabilizing real output than does a fixed exchange rate these results undermine arguments favoring fixed exchange rates because they discipline monetary policy in addition it is demonstrated that managed floating rules and exchange rate feedback rules are irrelevant for the distribution of real output

aspects of the optimal management of exchange rates abstract this paper shows that the choice of the optimal exchange rate regime depends on the stochastic shocks affecting the economy the higher the variance of real shocks the larger the desirability of fixity of exchange rates the desirability of exchange rate flexibility increases the larger are the variances of the shocks to the demand for money to the supply of money to foreign prices and to purchasing power parities when the economy produces traded and non traded goods the desirability of exchange rate flexibility diminishes the higher is the relative share of non traded goods and the lower are the elasticities of demand and supply of the two goods

dynamic stability in a model of dual exchange rates abstract the dynamic stability of a small open economy operating under a regime of dual exchange rates is shown to depend on residents net foreign asset position this result is in contrast to the economy s dynamic behavior under unified fixed rate and flexible rate regimes where stability is unrelated to net foreign asset position

ppp strikes back aggregation and the real exchange rate we show the importance of a dynamic aggregation bias in accounting for the ppp puzzle we prove that the aggregate real exchange rate is persistent because its components have heterogeneous dynamics established time series and panel methods fail to control for this using eurostat data we find that when heterogeneity is taken into account the estimated persistence of real exchange rates falls dramatically its half life for instance may fall to as low as eleven months significantly below the consensus view of three to five years

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

inflation and output dynamics with state dependent pricing decisions this paper studies a state dependent pricing model in which firms face a fixed cost of changing their pricing plans a pricing plan specifies an entire sequence of time varying future prices allowing firms to choose a pricing plan rather than a single price generates inflation inertia in the response of the economy to small changes in the growth rate of money allowing firms to choose when to change their pricing plan generates a non linear response of inflation and output to small and large changes in the money growth rate the non linear solution method also reveals that the model generates an asymmetric response of output and inflation to monetary expansions and contractions

anticipated shocks and the acceleration hypothesis the implication of wage indexation in his well cited contribution sachs 14 sets up a macromodel embodying the wage setting process perfect foresight and the portfolio balance feature it examines the exchange rate and current account responses to unanticipated fiscal expansion under alternative wage indexation rules he finds that in the nominal wage rigidity no wage indexation model the exchange rate depreciation coincides with a current account deficit in the real wage rigidity full wage indexation case the exchange rate again depreciates with a current account deficit and appreciates with a surplus 14 744 45 sachs s result is consistent with kouri s 12 acceleration hypothesis a current account deficit is accompanied by currency depreciation and conversely after the publication of the dorbusch and fischer 8 paper the literature on acceleration hypothesis has shifted from unanticipated shocks to anticipated shocks dorbusch and fischer 8 find that a negative correlation between the exchange rate and the current account prevails prior to the implementation of anticipated shocks consequently their conclusion indicates the acceleration hypothesis is not held when the economy experiences anticipated shocks bhandari 4 and papell 13 claim that the status of current account and the response of exchange rate can have either a positive or a negative correlation in response to anticipated shocks based on the fact that sachs 14 does not deal with the anticipated disturbances the first purpose of this paper thus tries to shed light on whether the alternative wage indexation schemes will affect the validity of the acceleration hypothesis in response to an anticipated fiscal expansion in an interesting paper aoki 1 bases on the modified dorbusch 7 model and examines the exchange rate responses to anticipated supply shocks he finds that an entirely different type of exchange rate adjustment pattern misadjustment path can arise when economic vari

exchange rate regimes in transition italy 1974 in order to explain the behavior of the lira during the operation of the italian two tier exchange market in 1973 74 we develop a model of exchange rate regimes in transition on the assumption that the market will set exchange rates so as to eliminate speculative profits at the time of transition the model indicates that expectations of a transition combined with uncertainty about the nature of the post transition regime can cause a jump in exchange rates at the moment of transition as well as volatile exchange rate movements prior to the transition the model suggests that the perceived temporariness of an exchange rate regime should be treated as a market fundamental

materials price increases and aggregate adjustment in an open economy a stochastic approach abstract this paper develops a stochastic macroequilibrium frameworks to analyze the differing implications of alternative types of input price disturbances the distinctions between expected and unexpected permanent and transitory nominal and real disturbances are considered the introduction of input disturbances involves a more elaborate modelling of the supply side of the economy both constant returns to scale and decreasing returns to scale technologies are considered the analysis highlights the sensitivity of the macroeconomic impacts of input price shocks to their specific type the analytical results obtained are not unambiguous and are supplemented with numerical simulations

exchange rate differential and balance of payments under dual exchange markets abstract this paper develops a model of an economy that uses two exchange markets an official market in which the exchange rate is determined by central bank intervention and a free market in which the exchange rate is determined by market forces the official market handles selected imports and exports while the free market handles the remaining imports and exports and capital transactions the model is used to discuss the effects of various policies on the differential between the free and the official exchange rates and on the balance of payments

terms of trade and exchange rate regimes in developing countries abstract since friedman essays in positive economics university of chicago press chicago 1953 157 203 an advantage often attributed to flexible exchange rate regimes over fixed regimes is their ability to insulate more effectively the economy against real shocks i use a post bretton woods sample 1973 96 of 75 developing countries to assess whether the responses of real gdp real exchange rates and prices to terms of trade shocks differ systematically across exchange rate regimes i find that responses are significantly different across regimes in a way that supports friedman s hypothesis the paper also examines the importance of terms of trade shocks in explaining the overall variance of output and prices in developing countries

world business cycles under fixed and flexible exchange rates this paper studies the behavior of monthly industrial production indices during the recent periods of fixed and flexible exchange rate s the central conclusions are as follows industrial production indices are subject to stochastic trend growth the variances of the monthly growth rates are higher in the flexible exchange rate period than in the fixed exchange rate period and are related to the degree of openness and to national income more open economies tend to experience more variability while richer more diversified economies experience less and output movements have been correlated across countries under both exchange rate regimes and there is evidence of a world business cycle copyright 1988 by ohio state university press

international business cycles the authors estimate a dynamic two country model in which economic fluctuations are driven by a worldwide supply shock country specific supply shocks and relative fiscal money and preference shocks identification is achieved using only long run restrictions based on a theoretical model the main results are 1 supply shocks particularly country specific ones are very important in generating international business cycles and 2 although the post 1973 flexible exchange rate period has been inherently more volatile there are no differences in transmission properties of economic disturbances across exchange rate regimes for the endogenous variables they focus on copyright 1993 by american economic association

optimal wage indexation and monetary policy in an economy with imported raw materials abstract an economy s openness from the input side has important effects on the optimal design of its macroeconomic policies given the exchange rate regime the larger the share of imported raw materials in domestic production the smaller the optimal degree of wage indexation to unanticipated inflation alternatively given the wage indexation parameter the larger the share of imported raw materials in domestic production the smaller the optimal degree of foreign exchange intervention by the monetary authority the more flexible the exchange rate

price stickiness empirical evidence of the menu cost channel abstract a leading explanation in the economic literature is that monetary policy has real effects on the economy because firms incur a cost when changing prices using a unique database of cost and retail price changes we find that variation in menu costs results in up to 13 3 fewer price increases we confirm that these effects are allocative and have a persistent impact on both prices and unit sales we provide evidence that the menu cost channel operates only when cost increases are small in magnitude which is consistent with theory and provides the first empirical evidence of boundary conditions

optimal foreign exchange rate policy for a small open economy abstract this paper examines optimal exchange rate policy for a small open economy which faces temporary and pemanent real and nominal disturbances it demonstrates that exchange rate stabilization is desirable if most diturbances are nominal if most disturbances are real then stabilization should be greater 1 the greater the fraction of exchange rate variance accounted for by permanent disturbances 2 the greater the information available to firms in setting the wage 3 the greater the fraction of exchange rate variance attributed to domestic productivity shocks compared with foreign relative price shocks and 4 the more elastic is labor supply

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

openness relative prices and macro policies abstract this paper analyzes the role of relative prices in the conduct of wage indexation monetary policy and exchange rate policy in a small economy producing traded and nontraded goods under a managed float exchange rate regime it is shown that the beneficial effect of using relative prices in addition to aggregate prices as indicators for the conduct of the above policies increases with openness the response of policies to relative prices rises with openness and has dampening effects on the volatility of deviations from purchasing power parity

stabilization with wage indexation and exchange rate flexibility abstract this survey examines the role of wage indexation and exchange rate policy in dampening fluctuations in output around its target level it is demonstrated that the appropriate choice for wage indexation and exchange rate flexibility is highly sensitive to the nature and the relative importance of the shocks impinging upon the economy as well as to the relevant parameters in the economy moreover the question of the desired flexibility of the exchange rate should be studied in the context of wage indexation and vice versa this interdependence raises the possibility of both policies being complements or substitutes to each other depending on the number of shocks that perturb the economy

barriers to price convergence this paper investigates the existence of convergence clubs in the cross country price mechanism for 96 individual goods retail price levels across 40 countries available semi annually for 1990 2010 using a nonlinear factor model and threshold regression tools to our knowledge this is the first paper to find strong evidence for club convergence of retail prices these clubs emerge due to the interaction of traded and non traded factors for example countries that are physically closer to potential trade partners converge faster than countries in the high distance regime as long as they have low initial labor productivity or low initial income moreover being behind the technology frontier appears to be more conducive to price convergence for countries with relatively small physical distance from potential trade partners we interpret our findings as evidence of a local law of one price due to barriers to price convergence that influence the duration of the effect of price shocks

optimal government finance policy and exchange rate management in a stochastically growing open economy abstract optimal monetary policy is analyzed in a stochastic small open economy consisting of risk averse representative agents the analysis shows how optimal monetary policy should be directed toward an optimal interest rate target this target which maximizes the intertemporal utility of the representative agent is determined by balancing off the marginal gains of a higher interest rate on increased growth and the future consumption it generates against the marginal losses stemming from a reduction in the holdings of real money balances the paper shows how an appropriately set monetary growth rate eliminates the need for continuous intervention in the exchange market

afdc benefits and the inter urban variation in poverty among female headed households the percentage of families headed by females in poverty varies widely across metropolitan areas for example 8 37 of all families in albany georgia were female headed and in poverty in 1980 while in sheboygan wisconsin the figure was 1 1 though not as dramatic as this interregional difference intra regional variation can also be significant in detroit michigan 4 90 of families were femaled headed and in poverty and in the closest interstate metropolitan area toledo ohio the figure was 3 77 recent research into the behavior of low income femaleheaded families suggests that state benefit differentials in aid to families with dependent children afdc may in part be responsible in this paper we construct a model that explains an important and overlooked implication of non uniform benefit standards among states the inter urban variation in the size of the potential and actual afdc recipient population particular attention is given to 1 the impact of interurban differences in real afdc payments 2 the potential of afdc to alter the number of female headed families in poverty and 3 the relative importance of other urban characteristics in explaining the size of the potential and actual afdc recipient population the model uses 1980 census data and is estimated for all standard metropolitan statistical areas for which we were able to obtain data

adjustment to monetary policy and devaluation under two tier and fixed exchange rate regimes abstract the purpose of this paper is to determine whether a two tier exchange rate regime is more effective than a fixed rate regime in increasing a country s ability to pursue an independent monetary policy the analysis compares adjustment to a monetary policy and to a devaluation in the two exchange rate regimes in a portfolio model under imperfect assets substitutability it is shown that a two tier exchange rate regime is capable of reducing the current account effects of monetary injection or devaluation only in the long run in the short run however we can get a larger current account response under a two tier regime these results reflect the trade off between quantity and price adjustment

consumer search price dispersion and international relative price fluctuations this article develops a model of consumer search consistent with the evidence of substantial price dispersion and time spent shopping within countries to study international deviations from the law of one price lop and relative price fluctuations search frictions lead firms to price discriminate across markets based on the opportunity cost of search which depends on the local wage with productivity and taste shocks estimated from the data deviations from the lop are as volatile and persistent as in the data fluctuations in relative wages real exchange rates and the terms of trade are also consistent with the data

money prices and the current account in a dual exchange rate regime abstract this paper examines the behavior of money prices and the current account in a dual exchange rate regime where all current account transactions take place at a pegged official rate and all capital account transactions occur at a freely floating financial rate the adjustment of a small open economy to a monetary disturbance under this regime is compared to that found under unified fixed and flexible rates the results concerning the behavior of the economy under dual rates are shown to apply also to an economy operating with fixed rates and controls on the international movement of capital

special exchange rates for capital account transactions the governments of developing countries are constrained in the effective implementation of domestic policy by the interlinkages of national and international financial markets domestic macroeconomic conditions are influenced by the interaction of national and world interest rates and prices and through the impact of real exchange rates on employment the domestic responses to changes in these factors are often strong and rapid this article suggests that dual rates can indeed be used successfully as a strictly transitory policy to offset sudden shocks in capital markets the article develops models which indicate why these dual systems are able to prevent inflationary or recessionary pressures caused by a misaligned exchange rate in the short term while free capital account rates can cut the flow of capital flight however a dual rate system cannot prevent a possibly equivalent loss of foreign reserves that will ultimately result because of the impact of the overvaluation of the commercial rate on the trade balance in the longer term a dual rate system with a misaligned commercial rate exacerbates the government s deficit ultimately real wages must be cut and real interest rates raised to generate sufficient foreign exchange to finance the external debt thus a dual rate works well if the commercial rate is maintained close to the equilibrium level

the transmission of disturbances under alternative exchange rate regimes with optimal indexing the paper develops a general stochastic macroeconomic model that can be used to study the international transmission of disturbances under four alternative exchange rate systems uniform flexible exchange rates uniform fixed exchange rates and two versions of two tier exchange rates the analysis makes two general points first one cannot assume stability of structure when assessing the consequences of alternative exchange rate regimes for example the slope of the aggregate supply curve and the rationally formed expectations in the asset markets can respond dramatically to the government s choice of exchange rate regime second exchange rate regimes that provide full insulation from foreign disturbances may nevertheless be inferior to other regimes in terms of their ability to maximize social welfare

dual exchange rates capital controls and sticky prices abstract it is often argued that capital controls are an appropriate policy response to the exchange rate overshooting which occurs when asset markets adjust more rapidly than goods markets in this paper an intertemporal disequilibrium model of an open economy is developed in which the effect of capital controls is examined the results are contrasted with recent studies by adams and greenwood 1985 and obstfeld 1986 in which capital controls are evaluated within a purely equilibrium framework and thus inevitably take the form of a welfare reducing distortion

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

international price dispersion in state dependent pricing models menu cost models predict a hump shaped relationship between real and nominal exchange rate volatility the hump occurs at higher values of nominal exchange rate volatility the higher trade costs and lower international substitution elasticities are these predictions accord well with the negative relationship between relative price and nominal exchange rate volatility i document using a data set of prices collected in eastern europe in a volatile environment in contrast trade costs must be sufficiently high or international substitution elasticities low in order for the model to account for the positive correlation between real and nominal exchange rate volatility in the aggregate data

wage flexibility and openness this paper analyzes the degree of short run real wage flexibility in a two sector economy under floating rates this is done by deriving optimal wage indexation in a contracting framework we find that the more closed the economy the lower the degree of wage indexation as a result output will fluctuate less around its desired level in a more closed economy these findings further imply that a given unexpected monetary shock will cause as maller output shock in a more open economy whereas a given real shock will induce a smaller output shock in a more closed economy this abstract was borrowed from another version of this item

estimates of effective guarantees and tax rates in the afdc program for the post obra period we employ the model used by fraker moffitt and wolf 1985 to estimate effective tax rates and guarantees in the aid to families with dependent children afdc program for the years 1967 82 to produce comparable estimates for 1983 91 we compare this method of benefit prediction with other methods in the literature and clarify the interpretation of estimates generated using the fraker moffitt and wolf model we use our estimates for the period from 1983 to 1991 to examine how effective afdc tax rates and guarantee levels have changed over time and relative to nominal or official program parameters

government debt economic activity and transmission of economic disturbances this paper analyzes the effects of government debt on output and the trade bala nce in a two country rational expectations model of the world economy it is shown that perceived changes in government debt do not affect the level of economic activity but unperceived changes in the home country s government debt are correlated positively with its output and negatively with its trade balance unperceived increases in the foreign country s government debt however have a positive impact on the home country s output and the trade balance empirical evidence from the u s is consistent with most of the implications of the model copyright 1987 by ohio state university press

effective tax rates and guarantees in the afdc program 1967 1982 estimates of effective tax rates on earned and unearned income and estimates of effective guarantees in the afdc program by state are provided for the period 1967 1982 the results indicate that effective real guarantees fell every year from 1967 to 1981 but stabilized in 1982 effective tax rates on unearned income rose steadily from 1967 to 1981 and took a particularly large additional jump in 1982 effective tax rates on earned income fell after 1967 but then gradually rose throughout the 1970s until 1982 when they took a much larger jump thus guarantees fell and tax rates rose over the 1970s as tight budgets forced states to restrict benefits and in the early 1980s tax rates were pushed even higher by federal legislation

monetary and real shocks productive capacity and exchange rate regimes where producers may diversify internationally international diversification is shown to inuuce a positive correlation between the volatility of productivity shocks and investment in the presence of a phillips curve the expected gnp is lower under a floating exchange rate regime than under a fixed exchange rate regime this result applies both for real and monetary shocks attempts to reduce foreign direct investment by capital controls will tend to reduce welfare without affecting our results regarding the ranking of exchange rate regimes implies that in the presence of market power uncertainty tends to reduce investment in the first part of the paper i demonstrate the international diversi fication of production modifies this result foreign direct investment tends to offset the impact of market power on the concavity of the profit function by weakening the relative price effect associated with output changes and by increasing the flexibility of adjusting the variable input hence international diversification of production is shown to induce a positive correlation between the volatility of productivity shocks and investment the second part of the paper utilizes the framework presented in section i to re examine the welfare ranking of exchange rate regimes in the presence of capital mobility as is well appreciated a one dimensional answer regarding the merits of a fixed exchange rate regime will not do justice to the host of issues relevant for making the choice between exchange rate regimes the second part of the paper focuses on one aspect of the debate the linkages between volatility domestic and foreign direct investment and productive capacity a frequent argument in favour of exchange rate stability relates to the potential cost of exchange rate volatility which may work to increase the cost of international trade and to reduce its volume yet efforts to detect the adverse effects of exchange rate volatility on trade volumes in the last two decades have not delivered clear cut results in fact the experience of international trade among the united states canada europe and japan suggests that there is no natural

accounting for u s real exchange rate changes this study measures the proportion of u s real exchange rate movements that can be accounted for by movements in the relative prices of nontraded goods the decomposition is done at all possible h

the role of information acquisition and financial markets in international macroeconomic adjustment abstract international macroeconomic adjustment to money supply aggregate expenditure and relative demand disturbances is analyzed within a framework which emphasizes the role of information agents are unable to directly observe disturbances and may become fully informed about disturbances only by purchasing information we analyze how relative price and exchange rate adjustment depends on the variances of the underlying disturbances while taking into account the incentive to acquire information we also discuss the conditions which are necessary to preclude a free rider problem whereby uninformed agents are able to extract from observation of financial market conditions the exact information of the information buyers

optimal monetary policy endogenous supply and rational expectations abstract in this paper we demonstrate that the choice of monetary policy regime will affect the variability of output when private agents in forming their supply decisions take into account the authority s selection of a policy rule a striking feature of the analysis is that the choice between policy rules in sargent wallace 1975 framework but with endogenous aggregate supply depends only on the variability of aggregate demand under each rule and not on the variability of aggregate supply it follows that the choice of monetary policy rules reduces to the problem analyzed by poole 1970 in the stochastic keynesian structure

frequency of price adjustment and pass through we empirically document using u s import prices that on average goods with a high frequency of price adjustment have a long run pass through that is at least twice as high as that of low frequency adjusters we show theoretically that this relationship should follow because variable mark ups that reduce long run pass through also reduces the curvature of the proflt function when expressed as a function of the cost shocks making the flrm less willing to adjust its price lastly we quantitatively evaluate a dynamic menu cost model and show that the variable mark up channel can generate signiflcant variation in frequency equivalent to 37 of the observed variation in the data on the other hand the standard workhorse model with constant elasticity of demand and calvo or state dependent pricing has di culty matching the facts

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

expectations and exchange rate dynamics a state dependent pricing approach abstract this paper presents a two country dsge model with state dependent pricing as in dotsey et al dotsey m king r g and wolman a l 1999 state dependent pricing and the general equilibrium dynamics of money and output quarterly journal of economics 114 655 690 and variable demand elasticity as in kimball kimball m s 1995 the quantitative analytics of the basis neomonetarist model journal of money credit and banking 27 1241 1277 following a domestic monetary expansion the model predicts i positive hump shaped responses of domestic output and consumption ii positive spillover effects on foreign output and consumption iii a high international output correlation relative to consumption correlation iv a delayed increase in domestic and foreign inflation v a delayed nominal exchange rate overshooting vi a deterioration in the terms of trade and vii a j curve in the trade balance the model matches the impulse responses from an identified var more closely than an otherwise identical model with time dependent pricing

determinants of the spread in a two tier foreign exchange market abstract the determinants of the spread between the commercial and financial exchange rates are analyzed in a two tier exchange market model derived from utility maximization contrary to popular belief it is found that domestic policy and non policy variables have no effect on the spread only foreign factors matter

on the viability of monetary unions abstract this paper contrasts the notion of optimality with that of viability of monetary unions and attempts to provide a positive analysis of the latter by dwelling upon herbert simon s work on models of bounded rationality a macro model developed by frenkel and aizenman is appended to the above theoretical framework and it is shown that viability is strictly related to certain specific properties of the economy
