inflation persistence alternative interpretations and policy implications in this paper i consider the policy implications of two alternative structural interpretations of observed inflation persistence which correspond to two alternative specifications of the new keynesian phillips curve nkpc the first specification allows for some degree of intrinsic persistence by way of a lagged inflation term in the nkpc the second is a purely forward looking model in which expectations farther into the future matter and coefficients are time varying in this specification most of the observed inflation persistence is attributed to fluctuations in the underlying inflation trend which are a consequence of monetary policy rather than a structural feature of the economy with a simple quantitative exercise i illustrate the consequences of implementing monetary policy assuming a degree of intrinsic persistence that differs from the true one the results suggest that the costs of implementing a stabilization policy when the policymaker overestimates the degree of intrinsic persistence are potentially higher than the costs of ignoring actual structural persistence the result is more clear cut when the policymaker minimizes a welfare based loss function

the fisher hypothesis and the forecastability and persistence of inflation abstract for the period 1860 to 1939 the simple correlation of the u s commercial paper rate with the contemporaneous inflation rate is 0 17 the corresponding correlation for the period 1950 to 1979 is 0 71 this paper attributes this apparent change in the fisher relation to differences in the stochastic process of inflation rather than a change in any structural relationship between interest rates and expected inflation contrary to recent claims in the literature there is little evidence of inflation non neutrality in data from the pre world war i period

money velocity and the natural rate of interest abstract m1 velocity is approximately the permanent component of the short term rate this implies that agents in deciding how much wealth to allocate to non interest bearing m1 as opposed to interest bearing assets almost uniquely react to permanent shocks to the opportunity cost essentially ignoring transitory shocks this suggests that money demand models must be modified to allow for such distinct reaction to permanent and transitory variation in the opportunity cost of holding m1 under monetary regimes making inflation stationary permanent fluctuations in m1 velocity uniquely reflect to a close approximation permanent shifts in the natural rate of interest

fiscal paradise foreign tax havens and american business the tax haven affiliates of american corporations account for more than 20 percent of u s foreign direct investment and nearly a third of the foreign profits of u s firms american companies report extraordinarily high profit rates on their tax haven investments in 1982 this behavior implies that the revenue maximizing tax rate for a typical haven is around 5 8 percent american and foreign investment in tax havens has an uncertain effect on u s tax revenue but since low tax rates encourage american companies to shift profits out of high tax foreign countries it is possible that low foreign tax rates ultimately enhance u s tax collections

is there a role for monetary aggregates in the conduct of monetary policy abstract we examine the potential policy role of monetary aggregates by attempting to use them as effectively as possible in the analysis of empirical relationships we focus on their role as information variables since any more ambitious use such as in a policy rule would presuppose some information content in the aggregates our results show that in the united states since 1979 the monetary aggregates fall considerably short of those requirements and results with german m3 are hardly more favorable we also investigate whether empirical relationships are not reflective of information relationships because of the use of these variables in countercyclical policy the results are not consistent with that interpretation

multinationals profit response to tax differentials effect size and shifting channels this paper provides a quantitative review of the empirical literature on profit shifting behavior of multinational firms we synthesize the evidence from 25 studies and find a substantial response of profit measures to international tax rate differentials accounting for misspecification biases by means of meta regressions we predict a tax semi elasticity of subsidiary pre tax profits of about 0 8 moreover we disentangle the tax response by means of financial planning from the transfer pricing and licensing channel our results suggest that transfer pricing and licensing are the dominant profit shifting channel

price and wage inflation persistence across countries and monetary regimes abstract we augmented a macro model with intrinsic inflation inertia assuming that prices farer in the past are more likely to be reset we estimated the model for seven industrialized economies to compare their price wage structures and to explore the potential nexus between changes the price wage structure and changes in policy stances we find evidence for duration dependent price adjustments in all the country of the sample although positively sloped after few periods price hazard functions often become flat as in calvo based models instead wage hazard shapes are in line with taylor contracts with the exceptions of france and the united kingdom country comparison shows that price and wage stickiness are correlated regarding monetary policy stances no systematic effect is found observed changes are explained by country specific factors e g market reforms

fool s gold the impact of venezuelan currency devaluations on multinational stock prices this paper documents negative cumulative abnormal returns cars to five exchange rate devaluations in venezuela within the context of stiff exchange controls and large black market premiums using daily stock prices for 110 multinational corporations with venezuelan subsidiaries the results suggest evidence of statistically and economically significant negative cars of up to 2 07 percent over the ten day event window we find consistent results using synthetic controls to causally infer the effect of each devaluation on the stock prices of global firms active in the country at the time of the event our results are at odds with the predictions of the efficient market hypothesis stating that predictable devaluations should not affect the stock prices of large multinational companies on the day of the event and even less so when they happen in small countries we interpret these results as a suggestive indication of market inefficiencies in the process of asset pricing

taxes tariffs and transfer pricing in multinational corporate decision making three interrelated aspects of u s multinational corporation activity are analyzed here the ability to shift profits from high tax countries to low tax countries the impact of host country taxes and tariffs on the distribution of real capital and the influence of these policies on international trade patterns of the united states and host countries the cross sectional empirical analysis indicates that the observed pattern of reported profits in high and low tax countries is consistent with income shifting behavior and that real investment responds to host country effective tax rates and tariffs the united states appears both to import more from and export more to low tax countries where mnc investment is greater but this bilateral focus must be amplified to consider multilateral effects if trade benefits are to be projected copyright 1991 by mit press

catastrophic natural disasters and economic growth this paper examines the short and long run average causal impact of catastrophic natural disasters on economic growth by combining information from comparative case studies the counterfactual of the cases studied is assessed by constructing synthetic control groups taking advantage of the fact that the timing of large sudden natural disasters is an exogenous event it is found that only extremely large disasters have a negative effect on output both in the short and long run however this result appears in two events where radical political revolutions followed the natural disasters once these political changes are controlled for even extremely large disasters do not display any significant effect on economic growth it is also found that smaller but still very large natural disasters have no discernible effect on output

international corporate tax avoidance a review of the channels magnitudes and blind spots this paper reviews the rapidly growing empirical literature on international tax avoidance by multinational corporations it surveys evidence on main channels of corporate tax avoidance including transfer mispricing international debt shifting treaty shopping tax deferral and corporate inversions moreover it performs a meta analysis of the extensive literature that estimates the overall size of profit shifting we find that the literature suggests that for the most recent year a 1 percentage point lower corporate tax rate compared to other countries will expand before tax income by 1 5 percent an effect that is larger than reported as the consensus estimate in previous surveys and tends to be increasing over time the literature on tax avoidance still has several unresolved puzzles and blind spots that require further research

testing for indeterminacy an application to u s monetary policy reply this paper considers a prototypical new keynesian model in which the equilibrium is undetermined if monetary policy is passive the likelihood based estimation of dynamic equilibrium models is extended to allow for indeterminacies and sunspot fluctuations we construct posterior weights for the determinacy and indeterminacy region of the parameter space and estimates for the propagation of fundamental and sunspot shocks according to the estimated model u s monetary policy post 1982 is consistent with determinacy whereas the pre volcker policy is not we find that before 1979 indeterminacy substantially altered the propagation of shocks

american colonial monetary regimes the failure of the quantity theory and some evidence in favour of an alternate view recent developments in monetary economics suggest that the manner in which money is introduced is more important even for price level movements than the quantity of money colonial american experience provides a laboratory for testing this view it is shown that the nature of backing rather than the quantity of money determined its value large secular inflations were ended by changing the nature of backing despite continued large note issues and despite the absence of a metallic standard extremely large note issues and note withdrawals are shown not to have produced inflation currency depreciation or deflation currency appreciation

financial fragility and mexico s 1994 peso crisis an event window analysis of market valuation effects persistent cycles of devaluation debt repudiation and financial crisis have been recurrent themes in latin america and elsewhere this study focuses on one such event namely the mexican peso devaluation debt and financial sector crisis of 1994 95 this paper utilizes an event study framework with daily stock market data to document financial market responses to the unfolding crisis in particular we find that the devaluation itself was viewed as relatively benign by market participants the results also show little evidence that investors anticipated the peso devaluation the declining reserve levels of mexico s central bank and the increasing sovereign default risk of mexico however the results suggest that the equity markets did respond positively to remedial actions taken by governmental authorities such as the clinton bailout plan

real wage rigidities and the new keynesian model most central banks perceive a trade off between stabilizing inflation and stabilizing the gap between output and desired output however the standard new keynesian framework implies no such trade off in that framework stabilizing inflation is equivalent to stabilizing the welfare relevant output gap in this paper we argue that this property of the new keynesian framework which we call the divine coincidence is due to a special feature of the model the absence of nontrivial real imperfections we focus on one such real imperfection namely real wage rigidities when the baseline new keynesian model is extended to allow for real wage rigidities the divine coincidence disappears and central banks indeed face a trade off between stabilizing inflation and stabilizing the welfare relevant output gap we show that not only does the extended model have more realistic normative implications but it also has appealing positive properties in particular it provides a natural interpretation for the dynamic inflation unemployment relation found in the data

international income shifting by us multinational corporations this paper provides estimates of the amount of income shifted across national borders within the manufacturing operations of us multinational corporations mncs in 1988 it is assumed that each mnc arranges its investments such that after accounting for income shifting opportunities the after tax rate of return on a marginal investment is the same for all its affiliates regardless of location the income shifting is then inferred by comparing shares of after tax profits assets and sales of the affiliated members it is estimated that such shifting amounted to about 8 billion on net which is less than 4 of the worldwide taxable income of the manufacturing mncs

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

the foreign exchange exposure of japanese multinational corporations we find that about 25 percent of our sample of 171 japanese multinationals stock returns experienced economically significant positive exposure effects for the period january 1979 to december 1993 the extent to which a firm is exposed to exchange rate fluctuations can be explained by the level of its export ratio and by variables that are proxies for its hedging needs highly leveraged firms or firms with low liquidity tend to have smaller exposures foreign exposure is found to increase with firm size we also find that keiretsu multinationals are more exposed to exchange rate risk than nonkeiretsu firms it is conventional wisdom that exchange rate movements affect both the cash flows of a firm s operations and the discount rate employed to value these cash flows measuring foreign exchange exposure is now a central issue of international financial management and this issue has spawned a considerable amount of research existing empirical evidence on foreign exchange exposure however seems perplexing studies have so far documented a weak link between contemporaneous exchange rate fluctuations and stock returns of u s multinational firms 2 gendreau 1994 finds it difficult and unconvincing that the weak results imply that exchange rate changes have no effect on exporters stock returns bartov arnd bodnar 1994 attribute the observed insignificant relationship between exchange rate changes and st ock returns to probable problems associated with the previous studies samiple selection procedure or to mispricing caused by investors errors in estimat

investigating inflation persistence across monetary regimes under inflation targeting estimates of the indexation parameter in hybrid new keynesian phillips curves are either equal to zero or very low in the united kingdom canada sweden and new zealand analogous results hold for the euro area under the european monetary union and for switzerland under the new monetary regime under stable regimes with clearly defined nominal anchors inflation appears to be purely forward looking these results question the notion that the intrinsic inflation persistence found in post wwii u s data is structural in the sense of lucas carnegie rochester conference series on public policy 1 1976 19 46 and suggest that hardwiring inflation persistence in macroeconomic models is potentially misleading

currency crashes in emerging markets an empirical treatment we use a panel of annual data for over 100 developing countries from 1971 through 1992 to characterize currency crashes we define a currency crash as a large change of the nominal exchange rate that is also a substantial increase in the rate of change of nominal depreciation we examine the composition of the debt as well as its level and a variety of other macroeconomic factors external and foreign crashes tend to occur when output growth is low the growth of domestic credit is high and the level of foreign interest rates are high a low ratio of fdi to debt is consistently associated with a high likelihood of a crash

interpreting inflation persistence comments on the conference on quantitative evidence on price determination the past decade has seen important advances in the analysis of price setting behavior most notably in my view a great deal of effort has been directed at the development of models that on the one hand have an explicit behavioral interpretation the models are clear about who sets prices what they seek to achieve when choosing prices and to what constraints they are subject when making the decision and at the same time can be parameterized so as to be compared in detail to inflation data this has allowed these models to be incorporated into complete dsge models of business fluctuations and of the monetary transmission mechanism that can be econometrically estimated this raises the prospect that it should soon be possible to base policy analysis on models that are both quantitatively realistic and plausibly invariant under the kinds of changes in policy that the analyst may wish to contemplate some argue that these two desiderata remain in considerable tension with one another that one cannot insist upon optimizing foundations at least under the current state of knowledge without substantial sacrifice of quantitative realism it is somewhat unfair however to present the quest for a model with optimizing foundations as a retreat from full insistence upon empirical realism given the fact that models with clear behavioral interpretations can be checked against a wider range of types of empirical evidence which should ultimately allow greater confidence in the realism of the specification that can withstand such scrutiny for example the exhaustive recent study of evidence on price setting in the euro area undertaken by the eurosystem s inflation persistence network compares alternative models in the light of three distinct

the persistence of inflation in the united states abstract has the persistence of inflation in the united states changed since 1965 we estimate the persistence of inflation over time using different measures and estimation procedures and we produce confidence intervals for our estimates as well as formal tests of unchanged persistence we find that inflation persistence has been high and approximately unchanged in the u s over our sample period we reconcile our results with other studies that reached different conclusions

currency devaluation and stock market response an empirical analysis abstract we study local stock market reaction to currency devaluation by a country s central bank devaluations appear to be anticipated by the local stock markets and there are significant negative abnormal returns even one year prior to the announcement of the devaluation a negative trend in stock returns persists for up to one quarter following the first announcement and then becomes positive thereafter suggesting a reversal we explore whether changes in macroeconomic variables prior to currency devaluations are related to abnormal stock returns we find that stock returns are significantly lower if the devaluation is larger and if the country is a developing nation furthermore stock markets decline more around devaluations if reserves are lower if the real exchange rate has depreciated over the prior years if the capital account has declined if the current account deficit has gone up or if the country credit rating has deteriorated

stock returns following large one day declines evidence on short term reversals and longer term performance we examine stock returns following large one day price declines and find that the bid ask bounce and the degree of market liquidity explain short term price reversals further we do not find evidence consistent with the overreaction hypothesis we observe that securities with large one day price declines perform poorly over an extended time horizon while the concept of market overreaction has been noted for many years its formal description and examination is a relatively recent area of study debondt and thaler 1985 define the overreaction hypothesis as the overresponse to new information this hypothesis suggests that extreme movements in stock prices are followed by movements in the opposite direction to correct the initial overreaction and that the greater the magnitude of initial price change the more extreme the offsetting reaction one manner in which the overreaction hypothesis has been studied is the analysis of stock returns following large one day stock price declines brown harlow and tinic 1988 and atkins and dyl 1990 find significant reversals for stocks that experience one day price declines focusing on extreme price movements bremer and sweeney 1991 examine returns following one day price declines of 10 percent or more for fortune 500 firms that are in the center for research in security prices crsp data files they find significant positive three day abnormal returns over the period 1962 to 1986 and note that this three day recovery is inconsistent with stock prices fully and quickly reflecting relevant information they also suggest that market illiquidity may partially explain their findings the purpose of this study is to explain security return behavior following large one day declines our primary objective is to explore the role of the bid ask bounce market liquidity and overreaction in explaining price reversals in the three day period immediately following large one day declines large one day price declines are likely to be associated with substantial selling pressure enhancing the probability that a closing transaction is at a

some colonial evidence on two theories of money maryland and the carolinas recent developments in monetary economics stress the nature of monetary injections emphasizing that they have implications for the relationship between money and prices in contrast traditional approaches posit stable money demand functions that are independent of how money is injected the former approach implies that certain proportionality relations between money and prices need not obtain this permits the two approaches to be empirically distinguished but only if an appropriate experiment is conducted the colonial period is one such experiment colonial evidence suggests that the nature of injections is crucial to the effect on prices of changes in the money supply

imperfect credibility and inflation persistence in this paper we formulate a dynamic general equilibrium model with staggered nominal contracts in which households and rms use optimal ltering to disentangle persistent and transitory shifts in the monetary policy rule the calibrated model accounts quite well for the dynamics of output and insation during the volcker disinsation and implies a sacri ce ratio very close to the estimated value our approach indicates that insation persistence and substantial costs of disinsation can be generated in an optimizing agent framework without relaxing the assumption of rational expectations or relying on arbitrary modi cations to the aggregate supply relation jel classi cation e31 e32 e52

currency crises are they all the same abstract the plethora of currency crises around the world has fueled many theories on the causes of speculative attacks the first generation models focus on fiscal problems while the second generation models emphasize countercyclical policies and self fulfilling crises in the 1990s models pinpoint to financial excesses with the crisis of argentina in 2001 models of sovereign default have become popular again while the theoretical literature has emphasized variety the empirical literature has supported the one size fits all models this paper contributes to the empirical literature by assessing whether the crises of the last 30 years are of different varieties

the exchange rate exposure of u s multinationals this article examines the exposure of u s multinationals to foreign currency risk evidence is presented that the relationship between stock returns and exchange rates differs systematically across multinationals given these results the study focuses on the determinants of exchange rate exposure the comovements between stock returns and the value of the dollar is found to be positively related to the percentage of foreign operations of u s multinationals copyright 1990 by the university of chicago

the relation between common stock returns trading activity and market value this study examines the relation between common stock returns trading activity and market value our results indicate that although firm size and trading activity are highly correlated differences in trading activity are not the underlying reason for the firm size anomaly the finding of systematic differences in risk adjusted returns across stocks of firms of different size recent empirical research has revealed systematic differences in risk adjusted returns for common stocks of firms of different sizes as measured by the market value of outstanding common stock see banz 1 and reinganum 5 roll 7 in a recent paper has suggested that the firm size anomaly may result from errors in risk measurement in particular roll suggested that because small firms trade less frequently than large firms risk measures obtained from daily or weekly returns data may seriously underestimate the risk associated with holding a portfolio of small firms in response to roll s conjecture reinganum 6 examined the risk adjusted returns of portfolios formed on the basis of firm size using both the scholes williams 8 and the dimson 2 aggregated coefficient method of estimating portfolio betas and found that regardless of the beta estimation technique employed differences in estimated betas were insufficient to account for differences observed in the returns of size ranked portfolios if reinganum s 6 finding is correct that the firm size effect is not attributable to a misassessment of risk and if smaller firms trade less frequently than do larger firms then firm size may merely proxy for trading activity 1 thus the observed firm size effect may be explained in terms of a liquidity premium associated with inactively traded shares the purpose of this paper is to determine whether or not the firm size anomaly is explicable in terms of differences in the trading activity of common stocks a liquidity premium would provide a logically appealing explanation for the firm size effect tinic 11 demsetz 3 and others have argued that transactions costs vary inversely with trading activity as measured by average number of

a retrospective on the bretton woods system lessons for international monetary reform at the close of the second world war when industrialized nations faced serious trade and financial imbalances delegates from forty four countries met in bretton woods new hampshire in order to reconstruct the international monetary system over the next 25 years with currencies fixed to the american dollar world trade expanded vigorously inflation remained moderate and national income in industrialized countries rose faster than during any other period in this volume three generations of scholars and policy makers some of whom participated in the 1944 conference consider how the bretton woods system contributed to economic stability and rapid growth between 1945 and 1971 and discuss the future of the international monetary system in light of the bretton woods experience since president richard m nixon ended the bretton woods system in 1971 exchange rates have exhibited increasing flexibility after twenty years of floating rates however there is considerable interest in once again limiting exchange rate flexibility the apparent success of the european monetary system a fixed rate arrangement loosely based on the postwar system and the prospect of european monetary unification increase interest in a new internationally stable exchange rate moreover some academics and government officials see fixed rates as a way to help eastern europe and the former soviet union cope with pressing economic and political problems the economists historians political scientists and policy makers who contribute to this volume relate the bretton woods system to earlier fixed rate schemes and consider the political background of the original new hampshire meeting using recenteconomic theory for example work on time consistency and credibility they explore adjustment liquidity and transmission under the system the way it affected developing countries and the role of the international monetary fund in maintaining a stable rate the authors examine th

differential information and security market equilibrium we propose a simple model of equilibrium asset pricing in which there are differences in the amounts of information available for developing inferences about the returns parame ters of alternative securities in contrast with earlier work we show that parameter uncer tainty or estimation risk can have an effect upon market equilibrium under reasonable conditions securities for which there is relatively little information are shown to have relatively higher systematic risk when that risk is properly measured ceteris paribus the initially very limited model is shown to be robust with respect to relaxation of a number of its principal assumptions we provide theoretical support for the empirical examination of at least three proxies for relative information period of listing number of security returns observations available and divergence of analyst opinion

exchange rate movements and the profitability of u s multinationals abstract this paper studies the effects of unexpected exchange rate movements on the stock returns of u s multinationals unlike most previous studies of exchange rate exposure we explicitly consider the time variability of exchange rate exposure by taking into account firms foreign sales and foreign production information in our tests empirical results based on a sample of eighty u s multinationals from seven 3 digit sic manufacturing industries show that the stock market correctly reveals the profitability effects of exchange rate news predicted by theory a depreciation shock to the u s dollar for example has significant positive effects on the abnormal returns on the stocks of the multinationals through foreign sales and significant negative effects through foreign production

on the stability of money demand abstract we show that regulatory changes that occurred in the banking sector in the early 1980s that considerably weakened regulation q can explain the apparent instability of money demand starting in the same period we evaluate the effects of the regulatory changes using a model that goes beyond aggregates as m1 and treats currency and different deposit types as alternative means of payments we use the model to construct a new monetary aggregate that performs remarkably well for all the period 1915 2012

yesterday s bad times are today s good old times retail price changes are more frequent today than in the 1890s this paper documents differences in the nominal rigidity of retail prices across two 28 month periods 1889 91 and 1997 99 the most striking finding is that prices changed much less frequently in 1889 91 in the late 1800s when price changes did occur they were smaller on average and more narrowly distributed with fewer small or large price changes further price changes were more permanent 100 plus years ago these differences are consistent with a high occurrence of temporary price shocks and a higher cost of changing prices in 1889 91 than in 1997 99

trend inflation indexation and inflation persistence in the new keynesian phillips curve purely forward looking versions of the new keynesian phillips curve nkpc generate too little inflation persistence some authors add ad hoc backward looking terms to address this shortcoming we hypothesize that inflation per sistence results mainly from variation in the long run trend component of inflation which we attribute to shifts in monetary policy we derive a version of the nkpc that incorporates a time varying inflation trend and examine whether it explains the dynamics of inflation when drift in trend inflation is taken into account a purely forward looking version of the model fits the data well and there is no need for backward looking components jel e12 e31 e52 in this paper we consider the extent to which guillermo calvo s 1983 model of nominal price rigidities can explain inflation dynamics without relying on arbitrary backward looking terms in its baseline formulation the calvo model leads to a purely forward looking new keynesian

emerging market exchange rate exposure abstract we estimate the exposure of emerging market companies to fluctuations in their domestic exchange rates we use an instrumental variable approach that identifies the total exposure of a company to exchange rate movements yet abstracts from the influence of confounding macroeconomic shocks in the sub period of 1999 2002 we find that depreciations tend to have a negative impact on emerging market stock returns in the sub period of 2002 2006 this tendency has largely disappeared since we estimate the exchange rate exposure of firms from different countries with a common set of instruments we can make coherent cross country comparisons of their determinants we find that the impact of various measures of debt on exchange rate exposure which is negative and significant in the early sub period becomes insignificant and even reverses sign in the recent sub period

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

explaining exchange rate risk in world stock markets a panel approach using a garch approach we estimate a time varying two factor international asset pricing model for weekly equity index returns of 16 oecd countries a trade weighted basket of exchange rates and the msci world market index are used as risk factors we find significant currency risk exposures in country equity index returns we then explain these currency betas using several country specific macroeconomic variables with a panel approach we find that imports exports credit ratings and tax revenues significantly affect currency risks in a way that is consistent with some economic hypotheses similar conclusions are obtained by using lagged explanatory variables and thus these macroeconomic variables may be useful as predictors of currency risk exposures our results are robust to a number of alternative specifications

an empirical assessment of currency devaluation in east asian countries the hypothesis of contractionary devaluation has received surprisingly strong empirical support especially in the context of latin american countries in this paper we study whether it applies equally well in seven east asian countries when we use the pre 1997 crisis data and the trade weighted exchange rate we find no evidence of contractionary devaluations in fact currency devaluation appears strongly expansionary in several countries this is contrasted to the case of chile and mexico where the evidence of devaluation is persistent we find that the results are somewhat sensitive to the definition of the exchange rate and the period of estimation

identifying the influences of nominal and real rigidities in aggregate price setting behavior we formulate a generalized price setting framework that incorporates staggered contracts of multiple durations and that enables us to directly identify the influences of nominal vs real rigidities we estimate this framework using macroeconomic data for germany 1975 1998 and for the u s 1983 2003 in each case we find that the data are well characterized by nominal contracts with an average duration of about two to three quarters we also find that new contracts exhibit very low sensitivity to marginal cost corresponding to a relatively high degree of real rigidity finally our results indicate that backward looking price setting behavior such as indexation to lagged inflation is not needed in explaining the aggregate data at least in an environment with a stable monetary policy regime and a transparent and credible inflation objective

monetary policy rules in theory and in practice evidence from the uk and the us given the large amount of interaction between research on monetary policy and its practice this article examines whether some simple monetary policy rules that have been proposed in the academic literature part of which has originated from within central banks provide a reasonable characterization of actual policy in the united kingdom and the united states the article finds the simple rule that describes best the actual us monetary policy is a speed limit rule with dynamics whilst for the uk it is a forward looking rule the simpler dynamics in the uk s monetary policy rule are reflective of the lower persistence of inflation as a result of its policy of inflation targeting

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach

confidence sets for cointegrating coefficients based on stationarity tests standard methods for inference in cointegrating systems require all the variables to have exact unit roots and are not at all robust even to slight violations of this condition in this article i consider an alternative approach to inference in a cointegrating system this involves testing the hypothesis that a cointegrating vector takes on a specified value by testing for the stationarity of the associated residual confidence sets for the cointegrating vector can be constructed by exploiting the equivalence between tests and confidence sets this method has the advantage that it remains valid even if the regressors have roots that are not exactly equal to unity
