pricing to market of italian exporting firms this article investigates the pricing to market ptm behaviour of italian exporting firms using quarterly survey data by sector and by region over the period 1999q1 to 2005q2 a partial equilibrium imperfect competition model provides the structure according to which the orthogonality of structural shocks is derived impulse response analysis shows non negligible reactions of export domestic price margins to unanticipated changes in cost competitiveness and in foreign and domestic demand levels even though these effects appear to be of a transitory nature for the period 1999 to 2001 a typical ptm behaviour emerges while during the most recent years favourable foreign demand conditions allowed firms to increase their export domestic price margins in face of a strong deterioration of their cost competitiveness macroeconomic implications of the observed ptm behaviour are also discussed

nonlinear dynamics in deviations from the law of one price a broad based empirical study abstract in this paper we test empirically the validity of the law of one price using data for five major bilateral us dollar exchange rates and nine goods sectors during the recent floating exchange rate regime since the early 1970s using threshold autoregressive models we find strong evidence of nonlinear mean reversion in deviations from the law of one price with plausible convergence speeds consistent with theoretical arguments on international goods markets arbitrage under transactions costs and with an emerging strand of empirical literature these results contribute towards forming a consensus view in favor of discrete regime switching in deviations from the law of one price and the presence of differing nonzero transactions costs across a broad range of goods and countries

monetary union price level convergence and inflation how close is europe to the usa abstract the pattern of price dispersion across european and us cities from 1990 to 2004 is documented there is a striking decline in dispersion for traded goods prices in europe most of which took place prior to the launch of the euro dispersion in the euro area is now quite close to that of the usa this evidence provides useful facts for future work assessing the importance of various developments in europe harmonization of tax rates convergence of incomes and labor costs liberalization of trade and factor markets and increased coherence of monetary policy

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

expenditure switching vs real exchange rate stabilization competing objectives for exchange rate policy this paper develops a view of exchange rate policy as a trade off between the desire to smooth fluctuations in real exchange rates so as to reduce distortions in consumption allocations and the need to allow flexibility in the nominal exchange rate so as to facilitate terms of trade adjustment we show that optimal nominal exchange rate volatility will reflect these competing objectives the key determinants of how much the exchange rate should respond to shocks will depend on the extent and source of price stickiness the elasticity of substitution between home and foreign goods and the amount of home bias in production quantitatively we find the optimal exchange rate volatility should be significantly less than would be inferred based solely on terms of trade considerations moreover we find that the relationship between price stickiness and optimal exchange rate volatility may be non monotonic

exchange rate exchange rate volatility and foreign direct investment in the light of the importance of foreign direct investment fdi for the promotion of economic development this paper examines the impact of the changes in the real exchange rate and its volatility on fdi examining japan s fdi by industries we found that the depreciation of the currency of the host country attracted fdi while the high volatility of the exchange rate discouraged fdi our results suggest the need to avoid over valuation of the exchange rate and to maintain stable but flexible exchange rate in order to attract fdi

exchange rate pass through exchange rate volatility and exchange rate disconnect abstract this paper explores the hypothesis that high volatility of real and nominal exchange rates may be due to the fact that local currency pricing eliminates the pass through from changes in exchange rates to consumer prices exchange rates may be highly volatile because in a sense they have little effect on macroeconomic variables the paper shows the ingredients necessary to construct such an explanation for exchange rate volatility in addition to the presence of local currency pricing we need a incomplete international financial markets b a structure of international pricing and product distribution such that wealth effects of exchange rate changes are minimized and c stochastic deviations from uncovered interest rate parity together it is shown that these elements can produce exchange rate volatility that is much higher than shocks to economic fundamentals and disconnected from the rest of the economy in the sense that the volatility of all other macroeconomic aggregates are of the same order as that of fundamentals

u s real exchange rate fluctuations and relative price fluctuations abstract traditional theory attributes fluctuations in real exchange rates to changes in the relative price of nontraded goods this paper studies the relation between the united states bilateral real exchange rate and the associated bilateral relative price of nontraded goods for five of its most important trade relationships we find that this relation depends crucially on the choice of price series used to measure relative prices and on the choice of trade partner the relation is stronger when we measure relative prices using producer prices rather than consumer prices the relation is stronger the more important is the trade relationship between the united states and a trade partner even in cases where there is a strong relation between the real exchange rate and the relative price of nontraded goods however a large fraction of real exchange rate fluctuations is due to deviations from the law of one price for traded goods

price index convergence among united states cities we study the dynamics of price indices for major u s cities using panel econometric methods and find that relative price levels among cities mean revert at an exceptionally slow rate in a panel of 19 cities from 1918 to 1995 we estimate the half life of convergence to be approximately nine years the surprisingly slow rate of convergence can be explained by a combination of the presence of transportation costs differential speeds of adjustment to small and large shocks and the inclusion of nontraded goods prices in the overall price index do price indices in major u s cities share a common trend and if so how quickly do they revert to that trend following a local shock to the price index to answer this question we study the dynamics of consumer price indices for 19 major u s cities over the period from 1918 to 1995 the panel time series methods we employ are now commonly used for studying real output growth rates and levels of real exchange rates across countries we estimate that price index divergences across u s cities are temporary but surprisingly persistent with a half life of nearly nine years our research has two primary motivations first we hope to gain a better understanding of the sources of persistence in the deviations from purchasing power parity ppp found in studies of national price indices and exchange rate data second and more importantly we see the european monetary union as having many similarities to the united states and believe that studying the behavior of prices across u s cities will help us in understanding the likely nature of inflation convergence in the euro area the european central bank s stated inflation objective is a year on year change in the harmonized index of consumer prices hicp of not more than 2 but how large might we expect regional deviations from this euro area wide average to be and how long are they likely to persist the lack of data prevents us from answering this question directly using european prices under monetary union instead we look to the united states a mature common currency area of similar regional diversity size and industrial development

exchange rate volatility and international trade a general equilibrium analysis abstract we analyze the relation between exchange rate volatility and the volume of international trade in a general equilibrium stochastic endowment economy with imperfect international commodity markets and treating both variables as endogenous even in the simplest model the sign of the relation depends on the source for the change in volatility for instance more volatility of the endowments and higher costs to international trade both boost exchange risk and lower welfare but the first increases the expected volume of trade while the second decreases trade note that even the inter equilibria relation between trade and welfare is ambiguous

international monetary policy coordination and competitive depreciation a reevaluation is there a need for international coordination of monetary policies within the current system of floating exchange rates in a recent paper obstfeld and rogoff 1995 argue that in an environment of sticky prices under floating exchange rates monetary policy shocks will generate positive welfare spillovers across countries this leads to the conclusion that international monetary policy coordination is unnecessary and may in fact be undesirable since it nurtures a bias towards high inflation our paper shows that these conclusions are dependent on the manner in which prices are set when firms engage in pricing to market ptm setting prices in the currency of the buyer monetary policy tends to have negative welfare spillovers this gives an incentive to engage in competitive depreciation in a noncooperative equilibrium world inflation will be higher the greater the importance of ptm with a high degree of ptm it follows that the case for international monetary policy coordination is restored if ptm is at an intermediate range however international monetary coordination may have no consequences at all

choosing an exchange rate system abstract the focus of academic discussions of exchange rate policy has shifted in recent years the new literature on exchange rate regime choice emphasizes considerations relating to the problems of credibility in exchange rate targeting and the connections between exchange rate regime choices and choices of monetary and fiscal policy arguments for exchange rate targeting are reviewed under most circumstances and for most countries a system of freely floating exchange rates is likely to be a better choice than attempting to peg the exchange rate

systematic movements in real exchange rates in the g 5 evidence on theintegration of internal and external markets abstract many recent studies have documented the random behavior of real exchange rates this paper shows that real exchange rates defined for different sectors of an economy move closely together with one another even though each of the sectoral real exchange rates taken alone has a large random component the sectoral real exchange rates are tied together by internal price links due to factor mobility within each national economy any differences between real exchange rates which develop moreover can be explained almost entirely by productivity differentials at least in the long run this paper contrasts the strong ties which bind together prices from different sectors internally with ties that bind the prices of goods from the same sector internationally prices are shown to be much more highly correlated internally than externally because flexible exchange rates disrupt normal pricing relationships between goods from different countries

a model of relative national price levels under pricing to market abstract this paper proposes an alternative to the balassa samuelson theory of how relative price levels between countries are determined the theory is a general equilibrium formulation of a model where pricing to market arises endogenously from firm decisions it differs from balassa samuelson in that it centers on the distinction between segmented national goods markets rather than the distinction between traded and nontraded goods the paper also explores how balassa samuelson might be updated by combining it together with pricing to market elements applied to the case of a monetary union the theory offers an alternative explanation for the inflation differentials observed in emu it implies that such differentials may be a natural and enduring feature of a monetary union in which markets for goods and labor are less than fully integrated

purchasing power parity over two centuries abstract this paper re examines the purchasing power parity hypothesis for the dollar sterling exchange rate using the two centuries of data from lothian and taylor lt 1996 real exchange rate behavior the recent float from the perspective of the past two centuries journal of political economy 104 3 488 509 unlike lt we conclude that the dollar sterling rer is nonstationary implying a rejection of the long run ppp hypothesis the differences in our conclusions are explained by 1 sensitivity of adf unit root tests to the choice of lag length and or 2 the presence of significant time trends in the adf or phillips perron unit root test equations

productivity differentials the relative price of non tradables and real exchange rates abstract this paper reconciles the apparent contradiction between recent panel unit root tests of real exchange rates and the productivity differential model proposing an alternative view that explains the coexistence of such findings real exchange rates and the relative price of non tradables reflect the gradual adjustment of mean reverting and endogenously competing factors supply and demand shocks as well as traded goods arbitrage granger causality and variance decomposition results indicate substantial simultaneity and feedback effects between real exchange rates the relative price of non tradables and productivity differentials

can a real business cycle model without price and wage stickiness explain uk real exchange rate behaviour this paper establishes the ability of a real business cycle model to account for uk real exchange rate behaviour the model is tested by the method of indirect inference bootstrapping the errors to generate 95 confidence limits for a time series representation of the real exchange rate as well as for various key data moments the results suggest rbc models can explain real exchange rate movements

intranational business cycles in the united states abstract we established a comprehensive set of stylized facts for intranational business cycles across states and regions in the u s notable findings are that the cross correlations of our consumption measure is much less than that for output and the volatility of the real exchange rate between states is much less than that for output these findings are contrasted with the quantity and price anomalies found in international business cycle data additional results for labour and non labour earnings suggest that the observed amount of intratemporal risk sharing is quite limited as compared to that for intertemporal risk sharing

pass through in retail and wholesale this paper studies how prices comove across products firms and locations to gauge the relative importance of retailer versus manufacturer level shocks in determining prices i make use of a large panel data set on prices for a cross section of retailers in the u s i analyze prices at the barcode or universal product code upc level for individual stores i find that only 16 of the variation in prices is common across stores selling an identical product 65 of the price variation is common to stores within a particular retail chain but not across retail chains while 17 is completely idiosyncratic to the store and product product categories with frequent temporary sales exhibit a disproportionate amount of completely idiosyncratic price variation my results suggest that most of the observed price variation arises from retail level rather than manufacturer level demand and supply shocks however the behavior of prices is difficult to relate to observed variation in costs and demand at the retail level this suggests that retail prices may vary largely as a consequence of dynamic pricing strategies on the part of retailers or manufacturers rather than static demand and supply shocks this abstract was borrowed from another version of this item

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

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

a textbook example of international price discrimination we show that books for general audiences are similarly priced internationally but textbooks are substantially more expensive in the united states we argue that cost factors cannot explain this phenomenon and discuss several demand side explanations

exchange rate pass through and relative prices an industry level empirical investigation in this paper we explore the extent of exchange rate pass through for the usa uk and japan using a post bretton woods industry level dataset we investigate how different channels of exchange rate pass through affect domestic and import prices our analysis is suggestive of two channels of transmission and we find considerable variation in the extent of pass through across industries and countries

an examination of uncovered interest rate parity in segmented international commodity markets we examine the effect of segmented commodity markets on the relation between forward and future spot exchange rates in a dynamic economy we calculate the slope coefficient in our theoretical economy from regressing exchange rate changes on forward premia with reasonable parameter values the slope coefficient is less than unity however even for extreme parameters the slope is not less than zero as found in the data a negative slope coefficient in a nominal version of the model requires the covariance between monetary shocks and relative output shocks to be significantly negative in contrast to the covariance in the data one of the most studied relations in international finance is that between forward exchange rates and future spot rates empirical tests typically find that when one regresses changes in spot rates on forward premia the slope coefficient is less than one and often negative this result is called the forward bias anomaly and implies that the returns from investing in forward exchange contracts are predictable our objective is to examine the effect of segmentation of international commodity markets on the relation between the forward premium and the change in the spot rate segmentation of commodity markets is modeled by introducing a cost for transferring goods across countries giving rise to deviations from purchasing power parity ppp in this article we first derive the theoretical implications of the effect of segmentation on the forward bias in a dynamic general equilibrium model and then analyze a calibrated version of the model our analysis serves as a useful benchmark to study how much of the predictable deviations from uncovered interest parity uip can be explained by endogenous deviations from ppp

european product market integration after the euro using a detailed data set of prices of consumer goods in european cities from 1990 to spring 2003 we investigate the question of whether the introduction of the euro in january 1999 increased integration of consumer markets as reflected by consumer prices in fact we find no tendency for prices to converge after january 1999 this finding holds even when we control for a number of factors that might affect price dispersion on the other hand we find that there has been a significant reduction in price dispersion throughout the decade of the 1990s suggesting that efforts to reduce economic barriers initiated early in the decade may have in fact had the effect of significantly increasing the integration of consumer markets charles engel and john h rogers

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

the exchange rate and purchasing power parity extending the theory and tests abstract this paper analyzes the exchange rate in a no arbitrage or real business cycle equilibrium model and provides empirical evidence for this model vis a vis ppp our contribution is to show based on a generalization of the equilibrium model of exchange rates that i the test equation linking the exchange rate to fundamentals should allow for international heterogeneity in time preferences and risk attitudes as well as noise that is the model should not be tested as an exact relation ii empirical work should use levels of variables rather than first differences and iii tests on the existence of long run relations should be complemented by test on the signs of the coefficients our empirical work shows that as a long run relation the generalized model outperforms ppp moreover under the generalized model quarterly deviations from the estimated long term relation have a half life of only four to five quarters

haircuts or hysteresis sources of movements in real exchange rates abstract we empirically assess the importance of two sources of real exchange rate movements in models where ppp holds only among traded goods real exchange rate variation results from relative price movements within countries an alternative explanation relies on hysteretic price setting and nominal exchange rate changes using disaggregated price data from 11 oecd nations we find some support for the non traded goods models for example prices of haircuts in canada and the united states are unrelated in the long run we find stronger evidence to support models that emphasize sticky prices transportation costs or other impediments to frictionless trade

purchasing power parity and the role of traded goods evidence from eu states in this paper the debate on purchasing power parity ppp is considered by providing results with disaggregated price data from european countries the disaggregation of the price data is important because it allows for the consideration of goods that are likely tradable e g fruits with goods that are not tradable e g hotel rooms the european focus is important because these results are able to shed light on the effect of the type of exchange rate regime member of exchange rate mechanism erm or not

causes of nonlinearities in low order models of the real exchange rate abstract this paper investigates the extent to which modern dsge models which feature local currency pricing home bias nontraded goods and incomplete markets can generate nonlinear real exchange rate dynamics that are consistent with those found in the time series literature using data from the current floating period our key findings are as follows first if the true model can be appropriately characterized as a set of linear equations then linearity tests that utilize univariate autoregressions of the real exchange rate suffer from an omitted variables problem which leads them to overestimate the true incidence of nonlinearity consequently studies that fail to control for this problem may spuriously find evidence of nonlinearities in the data despite the fact that the data generating process may be linear second we propose a strategy that can largely eliminate this distortion finally we find that dsge models solved using higher order approximations are capable of generating true structural nonlinearities in real exchange rates both asymptotically and in short samples

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

how does a devaluation affect the current account abstract this paper explores how an exchange rate devaluation affects the current account in a sticky price inter temporal optimizing model the main issue addressed is how the features of international pricing affect the response of the current account when prices are all set in the producer s currencies the effect of a devaluation on the current account depends on the conventional marshall lerner conditions this is fundamentally an a temporal condition depending on the elasticity of substitution between home and foreign goods however when prices are all set in consumer s currencies the response of the current account depends upon the size of the inter temporal elasticity of substitution of consumption across time periods this represents an inter temporal condition when pricing to market is partial the effect of devaluation on the current account depends on the strength of the a temporal elasticity relative to the inter temporal elasticity

a corporate balance sheet approach to currency crises this paper presents a general equilibrium currency crisis model of the third generation in which the possibility of currency crises is driven by the interplay between private firms credit constraints and nominal price rigidities despite our emphasis on microfoundations the model remains sufficiently simple that the policy analysis can be conducted graphically the analysis hinges on four main features i ex post deviations from purchasing power parity ii credit constraints a la bernanke gertler iii foreign currency borrowing by domestic firms iv a competitive banking sector lending to firms and holding reserves and a monetary policy conducted either through open market operations or short term lending facilities we derive sufficient conditions for the existence of a sunspot equilibrium with currency crises we show that an interest rate increase intended to support the currency in a crisis may not be effective but that a relaxation of short term lending facilities can make this policy effective by attenuating the rise in interest rates relevant to firms

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

price setting in online markets basic facts international comparisons and cross border integration we document basic facts about prices in online markets in the united states and canada which is a rapidly growing segment of the retail sector relative to prices in regular stores prices in online markets are more flexible and exhibit stronger pass through 60 75 percent and faster convergence half life less than two months in response to movements of the nominal exchange rate multiple margins of adjustment are active in the process of responding to nominal exchange rate shocks properties of goods sellers and markets are systematically related to pass through and the speed of price adjustment for international price differentials

domestic market integration and regional economic growth china s recent experience from 1995 2011 summary this paper constructs an enhanced indicator for trade barrier and examines the endogenous relationship between market integration and regional economies across china from 1995 to 2011 beyond the current literature this study shows the endogenous relationship is significant reflecting a virtuous cycle domestic openness contributes to the economies in the central region more than in the other regions the feedback effect is stronger in the eastern and central regions than in the western and northeastern domestic openness and regional economies are adversely affected by state owned enterprises and government non productive expenditure several policy implications relevant to chinese economy are drawn from the findings

the comovement between output and prices abstract in this paper i analyze the comovement of us prices and output in the postwar period i use a new set of statistics to characterize the comovement between variables the statistics capture important information about the dynamics in the system the estimation procedure does not require assumptions about the order of integration or the types of assumptions needed for var decompositions i find that the comovement between output and prices is positive in the short run and negative in the long run i show that a model in which demand shocks dominate in the short run and supply shocks dominate in the long run can explain these empirical results while sticky price models with only demand shocks cannot

does exchange rate stability increase trade and welfare we develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare an important feature of the model is deviations from purchasing power parity caused by rigid price setting in buyers currency we find the following first exchange rate stability is not necessarily associated with more trade in a simple benchmark model with separable preferences and only monetary shocks trade is unaffected by the exchange rate system consistent with most evidence second both trade and welfare can be higher under either exchange rate system depending on preferences and on the monetary policy rules followed under each system finally in general there is no one to one relationship between the levels of trade and welfare across exchange rate systems

monetary policy in a low pass through environment in a dynamic new keynesian optimizing model we introduce incomplete exchange rate pass through on import prices three results stand out first unlike canonical models with perfect pass through which emphasize a type of isomorphism incomplete pass through renders the analysis of monetary policy of an open economy fundamentally different from the one of a closed economy second productivity driven deviations from the law of one price assume the interpretation of endogenous cost push shocks third the optimal commitment policy relative to discretion entails a smoothing of the deviations from the law of one price and requires more stable nominal and real exchange rates

real exchange rates and macroeconomics evidence and theory since the early 1980s a large body of research has thrown doubt on the relevance of macroeconomic models for understanding exchange rates the authors argue that a balanced reading of recent literature in exchange rate economics gives a more optimistic assessment many studies have established the pertinence of long run purchasing power parity ppp and the explanatory power of macroeconomic fundamentals in real exchange rate fluctuations a reasonably strong case can be made for a traditional macroeocnomic interpretation of real exchange rates which emphasizes short run price stickiness but long run ppp but a central new ingredient in this interpretation is the presence of international commodity market segmentation and persistent deviations from the law of one price an example is given of a dynamic general equilibrium model that can reproduce some of the observed features of real exchange rate fluctuations

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

explicit and implicit targets in open economies under a flexible inflation targeting regime should policymakers avoid any reaction to movements in the foreign exchange market using data for six advanced open economies explicitly targeting inflation this article examines empirically whether real exchange rate disequilibria systematically affect the conduct of monetary policy estimates indicate that monetary policy responses in inflation targeting open economies have changed significantly as the institutional framework for the conduct of monetary policy has evolved in particular an explicit target for core inflation and a greater use of the expectation channel of monetary policy appear to be the key features of the newest policy framework in this context central banks are unlikely to react to regular fluctuations in the exchange rate

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

exchange rate pass through and the effects of tariffs on economic performance and welfare abstract we develop a stochastic two country general equilibrium model where prices are determined under conditions of monopolistic competition to examine the macroeconomic and welfare effects of tariffs on the world economy under alternative nominal rigidities producer currency pricing pcp and local currency pricing lcp where the exchange rate pass through is absent we find that the significance of export pricing for the effects of tariffs depends critically upon whether tariffs are anticipated or unanticipated in the former case both pcp and lcp yield the same outcome as do perfectly flexible prices although the mechanism whereby this is achieved is different in the latter case the effects of unanticipated permanent tariffs are highly sensitive to the pricing scheme adopted by exporters leading to a wide range of conflicting outcomes involving tradeoffs among key parameters

aggregate real exchange rate persistence through the lens of sectoral data a novel approach to analyzing real exchange rate rer persistence and its sources is presented using highly disaggregated data for a group of eu 15 countries it is shown that the distribution of sectoral persistence is highly heterogeneous and skewed to the right so that a limited number of sectors are responsible for the high levels of persistence observed at the aggregate level quantile regression has been employed to investigate whether traditional theories such as the lack of arbitrage due to nontradability or imperfect competition combined with price stickiness are able to account for the slow reversion to parity of rers

putting the new open economy macroeconomics to a test abstract this paper explores one way to extend the new open economy macroeconomics in an empirical direction adapting maximum likelihood procedures it estimates and tests an intertemporal small open economy model with monetary shocks and nominal rigidities results offer mixed support for a benchmark model where prices are assumed to be sticky in the currency of the buyer price stickiness seems to be an important element as overall results are poorer for versions of the model in which prices either are flexible or are sticky in the currency of the producer the benchmark model does a better job explaining some variables than others in particular it does a poor job explaining exchange rate movements
