optimal interest rate rules asset prices and credit frictions we study optimal taylor type interest rate rules in an economy with credit market imperfections our analysis builds on the agency cost framework of carlstrom and fuerst 1997 agency costs net worth and business fluctuations a computable general equilibrium analysis american economic review 87 893 910 which we extend in two directions first we embed monopolistic competition and sticky prices second we modify the stochastic structure of the model in order to generate a countercyclical premium on external finance this is achieved by linking the mean distribution of investment opportunities faced by entrepreneurs to aggregate total factor productivity we model monetary policy in terms of simple welfare maximizing interest rate rules we find that monetary policy should respond to increases in asset prices by lowering interest rates however when monetary policy responds strongly to inflation the marginal welfare gain of responding to asset prices vanishes within the class of linear interest rate rules that we analyze a strong anti inflationary stance always attains the highest level of welfare

optimal price and inventory adjustment in an open economy model of the business cycle this paper presents a macroeconomic model containing optimizing inventory holding firms that is consistent with a number of prominent empirical regularities concerning fluctuations in output exchange rates relative prices and money prices are sticky but they are not predetermined still our model is consistent with exchange rate overshooting in the sense of dornbusch typical sticky price models allow a divergence between current production and current demand but this divergence is never allowed to feed back into the model our optimal inventory adjustments reconcile divergences between current demand and production and the inventory stock movements provide expected future dynamics

inflation targeting in emerging market and transition economies lessons after a decade abstract starting in the early 1990s several emerging market and transition economies adopted inflation targeting it in this paper we discuss a number of issues that arise in this context a the definition of it b the role of preconditions for it c the use of intermediate exchange rate targets and d the specification of inflation targets our overall conclusion is that suitably modified it is a useful policy strategy for emes

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

monetary and financial interactions in the business cycle this paper develops a computable general equilibrium model in which endogenous agency costs can potentially alter business cycle dynamics the model resembles the influential theoretical work of ben bernanke and mark gertler 1989 two sources of shocks are considered productivity shocks and monetary shocks the model is parametrized to match key features of u s aggregate activity the principal result of the analysis is that agency costs add very little to the basic business cycle dynamics copyright 1995 by ohio state university press

stabilization policy and the costs of dollarization this paper compares the welfare costs of business cycles in a dollarized economy to those associated with several alternative monetary regimes belonging to three broad families interest rate feedback rules inflation targeting and money growth rate rules the analysis is conducted within an optimizing model of a small open economy with sticky prices the model is calibrated to the mexican economy and is driven by 3external shocks terms of trade world interest rate and import price inflation we show econometrically that these shocks explain more than 75 of the observed forecasting error variance of mexican output and the mexican real exchange rate at 4 to 16 quarter horizons the welfare comparisons suggest that dollarization is the least successful of the monetary policy rules considered agents are willing to give up more than 2 of their non stochastic steady state consumption to see a policy other than dollarization implemented

spurious welfare reversals in international business cycle models several papers have documented spurious welfare reversals incompletemarkets economy produces a higher level of welfare than the completemarkets economy this paper first demonstrates how conventional linearization can generate approximation errors that can result in welfare reversals using a two country production economy we argue that spurious welfare reversals are not only possible but also plausible under reasonable values for model parameters this paper then proposes an approximation method that modifies the conventional linearization by a bias correction this method can be easily implemented and approximates welfare as accurately as a second order perturbation method

capital controls monetary policy and balance sheets in a small open economy we develop a small open economy new keynesian model that incorporates a financial accelerator in combination with liability dollarization applying a ramsey type analysis we compare the welfare implications of an optimal monetary policy under flexible exchange rates and an optimal capital control policy under fixed exchange rates in an economy without the financial accelerator an optimal monetary policy under flexible exchange rates is superior to an optimal capital control policy under fixed exchange rates in contrast in an economy with the financial accelerator an optimal capital control under fixed exchange rates yields higher welfare than an optimal monetary policy under flexible exchange rates jel e44 e52 f32 f38 f41

hedging and financial fragility in fixed exchange rate regimes currency crises that coincide with banking crises tend to share at least three elements first banks have a currency mismatch between their assets and liabilities second banks do not completely hedge the associated exchange rate risk third there are implicit government guarantees to banks and their foreign creditors this paper argues that the first two features arise from banks optimal response to government guarantees we show that guarantees completely eliminate banks incentives to hedge the risk of a devaluation our model also articulates one reason why governments might be tempted to provide guarantees to bank creditors guarantees lower the domestic interest rate and lead to a boom in economic activity but this boom comes at the cost of a more fragile banking system in the event of a devaluation banks renege on foreign debts and declare bankruptcy

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

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

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

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

productivity health and inequality in the intrahousehold distribution of food in low income countries a model is formulated incorporating linkages among nutrition labor market productivity health heterogeneity and the intrahousehold distribution of food and work activities in a subsistence economy empirical results based on a sample of households from bangladesh indicate that despite considerable intrahousehold disparities in calorie consumption households are averse to inequality furthermore consistent with the model the results also indicate that both the higher level and greater variance in the calories consumed by men relative to women reflect in part the greater participation by men in activities in which productivity is sensitive to health status copyright 1990 by american economic association

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

accounting for the east asian crisis a quantitative model of capital outflows in small open economies to what degree can the qualitative and quantitative aspects of the east asian crisis be accounted for within a dynamic general equilibrium model this paper investigates that question using a framework in which the crisis itself is modeled as an exogenous shock to the country risk premium this exercise has empirical discipline because the scale of the shock can be measured by the movement in the reported risk premium we calibrate a quantitative sticky price dynamic general equilibrium model of a small open economy to match the features of three east asian economies thailand korea and malaysia we identify a shock to the country risk premium using published data from international bond markets and identify shortrun monetary policy using observed domestic interest rates we find that the modeled response to the observed increase in external interest rates substantially matches macroeconomic data on prices and quantities at the aggregate and sectoral level however the model has more difficulty explaining the large exchange rate devaluations that occurred in those economies

new directions for stochastic open economy models the paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages explicit solution of the wage setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare expected output and the expected terms of trade despite the potential interplay between imperfections due to sticky wages and monopoly the optimal monetary policy rule has a closed form solution to motivate our model we show that observed correlations between terms of trade and exchange rates are more consistent with our traditional assumptions about nominal rigidities than with a popular alternative based on local currency pricing 2000 elsevier science b v all rights reserved

limits of floating exchange rates the role of foreign currency debt and import structure abstract a traditional argument in favor of flexible exchange rates is that they insulate output better from real shocks because the exchange rate can adjust and stabilize demand for domestic goods through expenditure switching this argument is weakened in models with high foreign currency debt and low exchange rate pass through to import prices the present study evaluates the empirical relevance of these two factors we analyze the transmission of real external shocks to the domestic economy under fixed and flexible exchange rate regimes for a broad sample of countries in a panel var and let the responses vary with foreign currency debt and import structure we find that flexible exchange rates do not insulate output better from external shocks if the country imports mainly low pass through goods and foreign indebtedness is high

import pricing and the trade balance in a popular model of exchange rate determination abstract this paper extends a popular model of exchange rate determination to include an import pricing relationship that is consistenc with imperfect competition in the importable sector the analysis highlights how import pricing behavior and aggregate macroeconomic relationships interact in determining the dynamics of the exchange rate the price of imports and the trade balance a basic prediction of the analysis is that an increase in the substitutability of imported product varieties in the domestic market will raise the responsiveness of the exchange rate and dampen the responsiveness of the trade account to monetary shocks

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

monetary policy in emerging markets can liability dollarization explain contractionary devaluations abstract in emerging markets external debt is denominated almost entirely in large developed country currencies such as the u s dollar this liability dollarization offers a channel through which exchange rate variation can lead to business cycle instability when firms assets are denominated in domestic currency and liabilities are denominated in foreign currency an exchange rate depreciation worsens firms balance sheets which leads to higher capital costs and contractions in capital spending to illustrate this i construct a quantitative sticky price small open economy model in which a monetary policy induced devaluation leads to a persistent contraction in output in this model fixed exchange rates offer greater stability than an interest rule that targets inflation

the structure of public debt and the choice of exchange rate regime this paper explores the relationship between the denomination of public debt and the choice of exchange rate regime three types of debt nominal indexed and foreign and two regimes fixed and flexible are considered indexed debt is insulated against unexpected inflation the real domestic currency value of foreign debt is subject to valuation effects from real exchange rate shocks the fear of floating result that foreign debt makes pegging more attractive is shown to hold unambiguously only if the peg is fully credible if the peg lacks credibility a critical factor is the perceived likelihood of using the escape clause of a switch to a float which raises the costs of pegging foreign debt increases the temptation to resort to the escape clause so when a peg is not fully credible as is almost always the case in reality pegging tends to be less attractive than floating in the presence of foreign debt ce memoire explore le rapport entre la denomination de la dette publique et le choix d un regime de taux de change trois types de dettes sont considerees nominale indexee etrangere et deux types de regimes taux fixes et taux flexibles la dette indexee est immunisee contre l inflation imprevue la valeur reelle en monnaie domestique de la dette etrangere est sujette a des effets attribuables aux chocs dans les taux de change reels la peur de laisser flotter le taux de change aide a comprendre qu une dette etrangere rend le taux fixe plus attrayant mais ce resultat est sans ambiguite seulement si le taux fixe est pleinement credible si le taux fixe manque de credibilite un facteur critique est la perception de la probabilite qu on va utiliser l echappatoire du passage au taux flottant ce qui augmente les cots d un taux fixe la dette etrangere accroit la tentation d avoir recours a la clause echappatoire ce qui fait que quand un taux fixe n est pas pleinement credible comme c est a peu pres toujours le cas en realite un regime de taux de change fixe tend a tre moins attrayant qu un regime de taux de change flottants quand il y a dette etrangere

hyteresis in import prices the beachhead effect this paper shows that temporary real exchange rate fluctuations can have persistent hysteretic effects on trade specifically when market entry costs are sunk sufficiently large exchange rate shocks alter domestic market structure and thereby induce hysteresis this simple result has strong implications for exchange rate theory t rade policy and estimation of trade equations empirical evidence su ggests that the recent dollar overvaluation induced hysteresis in u s import prices namely the aggregate pass through equation of exchange rates to import prices shifted in the 1980s the shift s nature and timing is broadly consistent with the hysteresis hypothesis copyright 1988 by american economic association

currency crises and monetary policy in an economy with credit constraints this paper presents a simple model of currency crises which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities the possibility of multiple equilibria including a currency crisis equilibrium with low output and a depreciated domestic currency results from the following mechanism if nominal prices are sticky a currency depreciation leads to an increase in the foreign currency debt repayment obligations of firms and thus to a fall in their profits this reduces firms borrowing capacity and therefore investment and output in a credit constrained economy which in turn reduces the demand for the domestic currency and leads to a depreciation we examine the impact of various shocks including productivity fiscal or expectational shocks we then analyze the optimal monetary policy to prevent or solve currency crises we also argue that currency crises can occur both under fixed and flexible exchange rate regimes as the primary source of crises is the deteriorating balance sheet of private firms

market sentiment and macroeconomic fluctuations under pegged exchange rates this paper models changes in market sentiment as a temporary increase in the premium faced by domestic private borrowers on world capital markets the effects of this shock are studied in an intertemporal optimizing framework of a fixed exchange rate economy where firms demand for working capital is financed by bank credit depending on the perceived length of this shock the model is capable of predicting a rise in domestic interest rates capital outflows and a drop in official reserves a reduction in bank deposits and the supply of credit a fall in private consumption a contraction in output and an increase in unemployment these predictions are consistent with observed facts associated with several recent episodes of turbulence on international financial markets

the exchange rate in a dynamic optimizing business cycle model with nominal rigidities a quantitative investigation this paper studies a quantitative dynamic optimizing business cycle model of a small open economy with staggered price and wage setting the model exhibits exchange rate overshooting in response to money supply shocks the predicted variability of the nominal and especially of the real exchange rate is noticeably higher than in standard real business cycle models with flexible prices and wages a positive domestic money supply shock is predicted to lower the domestic interest rate raise gdp and trigger a depreciation of both the nominal and real exchange rate increases in domestic productivity and in the world interest rate are also predicted to induce a nominal and real exchange rate depreciation 2001 elsevier science b v all rights reserved

growth effects of currency mismatches evidence from emerging economies this article investigates empirically the effects of currency mismatches on economic growth and volatility of growth in emerging market economies using the arellano bond dynamic panel data approach the analyses provide evidence on the presence of adverse growth effects of currency mismatches this illustrates the crucial role played by foreign currency denominated debts in the propagation mechanism of contractionary depreciations in emerging economies in the last decade further evidence from estimations implies that the adverse effects of mismatches on growth and growth volatility are more pronounced with higher exchange rate fluctuations

distinguished lecture on economics in government exchange rate regimes is the bipolar view correct the choice of appropriate exchange rate regime which for economies with access to international capital markets increasingly means a move away from the middle ground of pegged but adjustable fixed exchange rates towards the two corner regimes of either flexible exchange rates or a fixed exchange rate supported if necessary by a commitment to give up altogether an independent monetary policy lawrence h summers 2000 p 8

exchange rate exposure abstract in this paper we examine the relationship between exchange rate movements and firm value we estimate the exchange rate exposure of publicly listed firms in a sample of eight non us industrialized and emerging markets we find that exchange rate movements do matter for a significant fraction of firms though which firms are affected and the direction of exposure depends on the specific exchange rate and varies over time suggesting that firms dynamically adjust their behavior in response to exchange rate risk exposure is correlated with firm size multinational status foreign sales international assets and competitiveness and trade at the industry level

exchange rates and monetary policy in emerging market economies this paper investigates the effects of exchange rate regimes and alternative monetary policy rules for an emerging market economy that is subject to a volatile external environment in the form of shocks to world interest rates and the terms of trade in particular we highlight the impact of financial frictions and the degree of exchange rate pass through in determining the relative performance of alternative regimes in stabilizing the economy in the face of external shocks our results are quite sharp when exchange rate pass through is high a policy of non traded goods inflation targeting does best in stabilizing the economy and is better in welfare terms when exchange rate pass through is low however a policy of strict cpi inflation targeting is better in all cases a fixed exchange rate is undesirable in addition financial frictions have no implications for the ranking of alternative policy rules

patience persistence and welfare costs of incomplete markets in open economies abstract we investigate the welfare implications of alternative financial market structures in a two country endowment economy model we obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only internationally traded asset and we compare this welfare level with that obtained under complete asset markets the welfare cost of incomplete markets is negligible if agents are very patient and shocks are not very persistent but this cost is dramatically larger if agents are relatively impatient and shocks are highly persistent for realistic cases in which agents are very patient and shocks are highly persistent the welfare cost of incomplete markets is highly sensitive to the specific values of these parameters

international debt deleveraging i provide a framework for understanding debt deleveraging in a group of nancially integrated countries during an episode of international deleveraging world consumption demand is depressed and the world interest rate is low reecting a high propensity to save if exchange rates are allowed to oat deleveraging countries can depreciate their nominal exchange rate to increase production and mitigate the fall in consumption associated with debt reduction the key insight of the paper is that in a monetary union this channel of adjustment is shut o and therefore the falls in consumption demand and in the world interest rate are amplied hence monetary unions are especially prone to hit the zero lower bound on the nominal interest rate and enter a liquidity trap during deleveraging in a liquidity trap deleveraging gives rise to a union wide recession which is particularly severe in high debt countries the model suggests several policy interventions that mitigate the negative impact of deleveraging on output in monetary unions

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

exchange rate pass through when market share matters the authors investigate the pass through from exchange rates to import prices when firms future demands depend on their current market shares they show that profit maximizing foreign firms may either raise or lower their dollar export prices when the dollar appreciates temporarily i e the pass through may be perverse and that current import prices may be more sensitive to expected future exchange rates than to current exchange rates they present evidence that suggests the behavior of expected future exchange rates may provide a clue to the puzzling recent behavior of u s import prices copyright 1989 by american economic association

educational choice families and young people s earnings this paper presents two optimizing models of educational choice discusses issues of identification estimates earnings equations in the context of these models and presents conditions under which we can test one against the other the estimates indicate that education is endogenous for young people s earnings creating a downward bias in estimated returns from education that assume exogeneity identification and estimation relies on family background information from a special sample from the british household panel study 1991 95 which matches mothers and their young adult children our estimates favor a family model over an individual model and they suggest that parents allocate resources to education to compensate for differences in their children s earnings endowments

the external wealth of nations measures of foreign assets and liabilities for industrial and developing countries abstract although capital flows are closely monitored surprisingly little is known about the accumulated stocks of foreign assets and liabilities held by various countries especially in the developing world this paper constructs estimates of foreign assets and liabilities and their equity and debt subcomponents for a sample of 67 industrial and developing countries it characterizes the stylized facts of international balance sheets and asks whether there are trends in net foreign asset positions and shifts in debt equity ratios over time finally it explores the sensitivity of estimated stock positions to the treatment of valuation effects not captured in balance of payments data

the information content of the interest rate and optimal monetary policy optimal monetary policy rules are derived in a rational expectations cum contracting framework monetary policy is redundant if wage setters exploit the incomplete current information embodied in today s nominal interest rate however the monetary authorities can save wage setters the costs of indexing to the interest rate a contemporaneous money supply feedback rule is as effective as wage indexation a lagged rule relevant under a regime of money supply targeting is also as effective if investors use the interest rate both rules have the same implications for the real interest rate as poole s combination policy however the two rules have strikingly different implications for the nominal interest rate

the new open economy macroeconomics a survey since the 1995 publication of obsteld and rogoff s redux model there has been an outpouring of research on open economy dynamic general equilibrium models that incorporate imperfect competition and nominal rigidities this paper offers an interim survey of this recent literature 2001 elsevier science b v all rights reserved

financial crises and exchange rate policy this paper studies exchange rate policy in a small open economy model featuring an occasionally binding collateral constraint and fisherian deation the goal is to evaluate the performance of alternative exchange rate policies in sudden stop prone economies the key element of the analysis is a pecuniary externality arising from frictions in the international credit markets which creates a trade o between price

a new look at pass through abstract this paper examines the relationship between exchange rates and prices rather than assuming exchange rate changes are exogenous shocks that affect prices i use a long run restrictions var to identify shocks and explore the way domestic prices import prices and exchange rates react to a variety of shocks consumer price pass through is nearly complete in response to some shocks but low in response to others alternatively import prices and exchange rates typically respond in the same direction and pass through seems quick this supports the idea that import prices are set in the producer s currency and that lower cpi pass through is a result of changes in quantities or margins further down the supply chain

macroeconomic aspects of exchange rate pass through abstract this paper addresses the cause of the variability in exchange rate pass through we develop a model in which foreign exporters setting prices under uncertainty infer the value of domestic income and prices based upon their observation of the exchange rate and their knowledge of the stochastic structure of the economy this inference problem links pass through to the underlying stochastic macroeconomic structure of the economy rather than the source direction or size of the endogenous exchange rate movement that period the predictions of the model are consistent with pass through experience in the united states during the past decade

financial liberalization and banking crises in emerging economies abstract financial liberalization often leads to financial crises this link has usually been attributed to poorly designed banking systems an explanation that is largely static in this paper we develop a dynamic explanation by modelling the evolution of a newly liberalized bank s opportunities and incentives to take on risk over time the model reveals that even if a banking system is well designed in the sense of having good long run properties many countries will enjoy an initial period of rapid low risk growth and then enter a period with an elevated risk of banking crisis this transition emerges because of the way in which the degree of foreign competition the marginal product of capital and the bank s own net worth simultaneously evolve

exchange rates and prices the adjustment of relative prices to exchange rate movements is explained in an industrial organization approach given labor costs in the respective currencies exchange rate movements change costs for firms selling in the home market and thus disturb the industry equilibrium the extent of absolute and relative price adjustment is shown to depend on market integration product substitutability the relative number of domestic and foreign firms and the market structure the impact of exchange rates on prices is illustrated in a variety of approaches including the cournot a dixit and j stiglitz 1977 and s salop 1979 models some empirical evidence is offered in support of the theory copyright 1987 by american economic association
