the law of one price conditional convergence evidence from disaggregated data this article contributes to the literature on the law of one price lop and absolute purchasing power parity ppp in two ways first it uses a novel set of ppp data from the international comparison programme for oecd countries and 195 internationally comparable products from 1980 to 1996 second it derives and applies a test of conditional convergence which does not require long time spans or high frequency data between 1990 and 1996 for 10 out of 23 countries a significant reduction in the variance of the deviations from lop is found for tradeables but none in case of nontradeables for the former the deviations from lop close out at half lives between 2 2 and 6 3 years however there are also persistent country specific deviations from lop parities

revisiting purchasing power parity for african countries with nonlinear panel unit root tests this study applies panel seemingly unrelated regressions sur kapetanios et al kapetanios shin snell kss surkss tests proposed by wu and lee 2009 to investigate the properties of long run purchasing power parity ppp in 15 african countries the empirical results from the univariate unit root and panel based unit root tests indicate that ppp does not hold for these 15 countries under study however panel surkss tests indicate that ppp is valid for four of these 15 countries these results have important policy implications for these 15 african countries under study

purchasing power parity modeling and testing mean reversion abstract a model of mean reversion of exchange rates to purchasing power parity is developed and tested where exchange rates are assumed to follow a mean reverting elastic random walk toward a stochastic ppp rate the model recognizes the possibility that mean reversion towards ppp may be nonlinear which allows greater flexibility in the adjustment process regression equations consistent with the theoretical model are derived the model is tested using long and short term data for six countries while the results are generally consistent with the findings of previous studies evidence is presented which demonstrates that the mean reversion process is not linear for some countries

crossing the lines the conditional relation between exchange rate exposure and stock returns in emerging and developed markets this paper examines the importance of exchange rate exposure in the return generating process for a large sample of non financial firms from 37 countries we argue that the effect of exchange rate exposure on stock returns is conditional and show evidence of a significant return impact to firm level currency exposures when conditioning on the exchange rate change we further show that the realized return to exposure is directly related to the size and sign of the exchange rate change suggesting fluctuations in exchange rates as a source of time variation in currency return premia for the entire sample the return impact ranges from 1 2 to 3 3 per unit of currency exposure and it is larger for firms in emerging markets compared to developed markets overall the results indicate that foreign exchange rate exposure estimates are economically meaningful despite the fact that individual time series results are noisy and many exposures are not statistically significant and that exchange rate exposure plays an important role in generating cross sectional return variation moreover we show that the relation between exchange rate exposure and stock returns is more consistent with a cash flow effect than a discount rate effect

nonlinear adjustment to purchasing power parity in the post bretton woods era abstract this paper models the dynamics of adjustment to long run purchasing power parity ppp over the post bretton woods period in a nonlinear framework consistent with the presence of frictions in international trade we estimate exponential smooth transition autoregressive estar models of deviations from ppp which are obtained using the johansen cointegration method for both consumer price index cpi and wholesale price index wpi based measures and a broad set of us trading partners in several cases we find clear evidence of a mean reverting dynamic process for sizable deviations from ppp with the equilibrium tendency varying nonlinearly with the magnitude of disequilibrium analysis of impulse response functions also supports a nonlinear dynamic structure but convergence to long run ppp in the post bretton woods era is very slow

explaining the effect of rapid internationalization on horizontal foreign divestment in the retail sector an extended penrosean perspective we adopt a penrosean perspective to study the effect of rapid international expansion on the subsequent divestment of international operations we draw on regional strategy theory and differentiate penrosean managerial resources by their geographical fungibility to argue that the effect of rapid international expansion on the divestment of international operations varies with the regional patterns of firms international expansion and international experience we test our hypotheses using two stage least squares 2sls estimation on data that capture the international expansion and divestment of retailers over the period 2003 2012

short memory and the ppp hypothesis abstract the purchasing power parity ppp puzzle has been framed in recent years in terms of half lives of real exchange rate shocks that exceed 3 years recent studies have attempted to solve that puzzle by adopting nonlinear stochastic models of real exchange rates the notion of half life is fundamentally linear and therefore is inappropriate for those nonlinear models we provide operational algorithms for estimating more general measures of persistence that are appropriate for nonlinear as well as linear models memory in mean and memory in distribution we study three parametric models autoregression threshold autoregression and exponential smooth threshold autoregression our monte carlo simulations suggest that all three models can produce biased estimates of persistence measures depending on the true data generating process in addition the sample size is found to be too small for reliable nonparametric estimation suggesting that we need to impose parametric structure in the empirical application all three parametric models provided general support for the long term ppp hypothesis suggesting that there is no puzzle and questioning the need for recently introduced nonlinear models

escalation of commitment in venture capital decision making differentiating between domestic and international investors drawing upon an escalation of commitment framework this study investigates how differences between cross border and domestic venture capital investors in emotional social and institutional factors affect their decision to terminate an unsuccessful investment we track the exit outcome of 1060 venture capital investments in 684 european technology companies results show that domestic investors have a high tendency to escalate their commitment to a failing course of action while cross border investors terminate their investments efficiently even when investing through a local branch this is explained by cross border investors having a lower social and emotional involvement with the project and a lower embeddedness in the local economic and social environment decreasing individual decision biases further they are affected to a lower extent by normative pressures to further invest from their co investment network local branches of cross border investors are also shielded from escalation of commitment we conjecture that their international investment committee acts as an organizational safeguard against individual decision biases domestic investors may hence benefit from mimicking the behavior of cross border investors

some new stylized facts of floating exchange rates abstract this paper re examines real exchange rate behavior of oecd currencies under the current float using the more extensive dataset that an additional decade s worth of experience has made available what emerges is a new set of stylized facts which suggest that the problems of the current float were not as commonly believed generic to that system but in fact rather specific being largely confined to one sub period the early and mid 1980s and one currency the us dollar this dollar behavior ranks as one of the important puzzles of the past 25 years

multi country evidence on the behavior of purchasing power parity under the current float abstract using panel data for the united states and 22 other oecd countries for the current float this paper presents evidence that despite substantial short term perturbations purchasing power parity actually performed much better than commonly believed average rates of growth of real exchange rates over long horizons bear little relationship either to average rates of growth of nominal exchange rates or to average inflation differentials thus implying a close to one to one relation between average rates of growth of nominal exchange rates and average inflation differentials panel data variants of standard unit root tests suggest that the real exchange rates of these countries can be characterized as mean reverting

a nonparametric measure of convergence towards purchasing power parity it has been claimed that the deviations from purchasing power parity are highly persistent and have quite long half lives under the assumption of a linear adjustment of real exchange rates however inspired by trade cost models nonlinear adjustment has been widely employed in recent empirical studies this paper proposes a simple nonparametric procedure for evaluating the speed of adjustment in the presence of nonlinearity using the largest lyapunov exponent of the time series the empirical result suggests that the speed of convergence to a long run price level is indeed faster than what was found in previous studies with linear restrictions copyright 2006 john wiley sons ltd

a panel project on purchasing power parity mean reversion within and between countries abstract previous time series studies have shown evidence of mean reversion in real exchange rates deviations from purchasing power parity ppp appear to have half lives of approximately four years however the long samples required for statistical significance are unavailable for most currencies and are potentially inappropriate because of regime changes in this study we re examine deviations from ppp using a panel of 150 countries and 45 annual post wwii observations our panel shows strong evidence of mean reversion that is similar to that from long time series ppp deviations are eroded at a rate of approximately 15 annually i e their half life is around four years such findings can be masked in time series data but are relatively easy to find in cross sections

smooth transition models and arbitrage consistency slow adjustment of real exchange rate towards equilibrium in linear models has long puzzled researchers stimulating the adoption of nonlinear models the exponential smooth transition model has been particularly successful providing faster adjustment speeds this paper discusses some of its theoretical limitations for example that expectations are adaptive we propose a new nonlinear model conceptually superior to the estar model since it is consistent with rational expectations one of its advantages is that it can be solved and estimated by nonlinear least squares using monthly post 1973 real exchange rate data we show that the model implies even faster speeds of adjustment

long run purchasing power parity during the recent float abstract this paper examines the relevance of long run purchasing power parity ppp which allows for measurement errors during the recent floating exchange rate period previous empirical studies generally fail to find support for long run ppp over this period in this paper in this paper the cointegration property of exchange rates and prices is examined using maximum likelihood procedure and we find significant evidence favorable to long run ppp further tests for symmetry and proportionality indicate that these two conditions are not generally with the data the results support the hypothesis of long run ppp with measurement errors in prices

price adjustment and exchange rate pass through abstract this paper develops a simple theoretical model that can be used to account for the determinants of exchange rate pass through to consumer prices while recent evidence has found low estimates of pass through in many countries there is little consensus on an explanation for this our paper argues that sticky prices represent a key determinant of exchange rate pass through we make this argument in two stages first holding the frequency of price change constant we show that our model calibrated to data from low inflation countries can reproduce the estimates of very low pass through for these countries the principal determinant of low pass through in this case is the slow adjustment of prices we then extend the model to allow the frequency of price change to be endogenous calibrating to a wider set of countries including both low inflation and high inflation countries we show that our model implies that exchange rate pass through is increasing in average inflation but at a declining rate performing the identical exercise on the data we find a striking correspondence between the predictions of the model and those of the data

a general equilibrium model of international portfolio choice we investigate in a two country general equilibrium model whether a bias in consumption towards domestic goods will necessarily lead to a preference for domestic securities we develop a model where investors are constrained to consume only from their domestic capital stock and where it is costly to transfer capital across countries in this model investors less risk averse than an investor with log utility bias their portfolios towards domestic assets investors more risk averse than log however prefer foreign assets thus this model suggests that it is unlikely that the portfolios observed empirically can be explained by the high proportion of domestic goods in total consumption we investigate in a two country general equilbrium model whether a bias in consumption toward domestic goods will necessarily lead to a preference for domestic assets in an investor s optimal portfolio we constrain investors to consume only from their domestic capital stock and introduce a proportional cost for transferring goods from one country this cost gives rise to endogenous deviations from the law of one price lop thus the home and foreign investors do not hold identical portfolios we show that an investor s optimal portfolio is biased towards domestic equity only if she is less risk averse than an investor with log utility investors with relative risk aversion greater than one exhibit a preference for the foreign asset this is because the exchange rate derived endogenously is negatively correlated with the return on the foreign asset and therefore the translated return on the foreign stock is less risky than that on the domestic stock thus the results of this model suggest that it is unlikely that the preference for domestic assets that is observed empirically can be explained by the high proportion of domestic goods in total consumption there exists a considerable body of literature documenting the gains from international diversification grubel 1968 was the first to propose that international diversification allows investors to attain lower return variances than those achievable by diversifying domestically this proposition relies on the correlation between stock indices across countries being significantly less

equivalence results for optimal pass through optimal indexing to exchange rates and optimal choice of currency for export pricing firms sometimes write price lists or catalogs for their exports so they set prices for a period of time and do not adjust prices during that interval in response to changes in their environment the firm sets the price either in its own currency or the importer s currency this paper draws a simple link between the choice of currency and the pricing decision of a firm that changes prices in response to all shocks specifically if the latter firm s price has a lower variance in terms of its own currency than the importer s currency then the firm with a price list will set the price in its own currency and otherwise it will set price in the foreign currency this relationship is established by consideration of the firm with a price list as a special case of a firm that indexes its export price to the exchange rate jel f4 f1

asymmetric price adjustment and economic fluctuations this paper considers a possible explanation for asymmetric adjustment of nominal prices the authors present a menu cost model in which positive trend inflation causes firms relative prices to decline automatically between price adjustments in this environment shocks that raise firms desired prices trigger larger price responses than shocks that lower desired prices the authors use this model of asymmetric adjustment to address three issues in macroeconomics the effects of aggregate demand the effects of sectoral shocks and the optimal rate of inflation copyright 1994 by royal economic society

are asian real exchange rates stationary by applying the newly developed nonlinear stationary test advanced by kapetanios et al journal of econometrics 112 2003 359 in examining the stationary property of 11 asian real exchange rates this paper rejects unit root in 8 us dollar based and 6 japanese yen based rates whereas the augmented dickey fuller adf test has led to no rejection at all

are real exchange rates nonstationary evidence from a panel data test it is well documented that real exchange rates between the united states and many industrialized countries in the post bretton woods period are integrated this result implies that purchasing power parity ppp does not hold even as a long run relationship this paper demonstrates that the failure to reject the unit root hypothesis may result from the low power of existing univariate test procedures i test for unit roots in real exchange rates by employing a more powerful panel based procedure using both cpi and wpi real dollar exchange rate data i strongly reject the null hypothesis of a unit root my results provide overwhelming support for the long run ppp under the current float copyright 1996 by ohio state university press

purchasing power parity over two centuries trends and nonlinearity in two recent contributions lothian and taylor and cuddington and liang produced empirical evidence that annual data for the dollar sterling real exchange rate spanning two centuries exhibited a non linear deterministic trend this trend could be proxying harrod balassa samuelson effects lothian and taylor showed that a linear stationary autoregressive mode which embodied a cubic trend implied much faster mean reversion of the real exchange rate to shocks than a model that excluded the trend this article shows that both non linearity and a deterministic trend can be allowed for in a theoretically appealing manner and that the fitted models provide a parsimonious explanation of both the dollar sterling and franc sterling real exchange rates over the two centuries of data generalized impulse response function analysis of the models demonstrates that the speed of adjustment to shocks can be even faster when trends are considered

low inflation pass through and the pricing power of firms abstract recently there has been a significant decline in the degree to which firms pass through changes in costs to prices a decline that is frequently characterized as a reduction in the pricing power of firms the decline appears to be associated with the decline in inflation in many countries the decline has important implications for monetary policy because it affects both forecasts of inflation and the effects of changes in monetary policy on inflation some have argued that the decline in pricing power helped to keep inflation low in the face of apparently strong demand pressures in the united states in the late 1990s this paper puts forth the view that the decline in pass through or pricing power is due to the low inflation environment that has recently been achieved in many countries first a microeconomic model of price setting is used to show that lower pass through is caused by lower perceived persistence of cost changes evidence is then presented showing that inflation is positively correlated with persistence of inflation suggesting that the low inflation itself has caused the low pass through an economy wide model consistent with the micromodel is then presented to illustrate how such changes in pricing power affect output and inflation dynamics in favorable ways but can disappear quickly if monetary policy and expectations change

exchange rate pass through to domestic prices does the inflationary environment matter abstract the paper tests a hypothesis suggested by j taylor 2000 low inflation pass through and the pricing power of firms european economic review 44 7 1389 1408 that a low inflationary environment leads to a low exchange rate pass through to domestic prices to test this hypothesis the paper derives a pass through relation based on new open economy macroeconomic models a large database that includes 1979 2000 data for 71 countries is used to estimate this relation there is strong evidence of a positive and significant association between the pass through and the average inflation rate across countries and periods the inflation rate moreover dominates other macroeconomic variables in explaining cross regime differences in the pass through

testing the purchasing power parity through i 2 cointegration techniques this paper contributes to the empirical literature on the purchasing power parity ppp over the post bretton woods period by providing a time series based interpretation of the controversial evidence characterizing the dynamics of real exchange rates it is shown that the persistence of deviations from the ppp between a set of european countries and the united states may be empirically attributed to the presence of i 2 stochastic trends in prices using consumer price indices interestingly the slow adjustment towards the equilibrium can be modelled through integral proportional equilibrium correction models and this evidence can be partly reconciled with theories where the inflation rate reduces the markup of profit maximizing firms acting on imperfectly competitive markets copyright 2005 john wiley sons ltd

prior to reshoring a duration analysis of foreign manufacturing ventures this paper throws light on the determinants of the duration of manufacturing offshore experiences by us and european firms prior to reshoring by applying survival analysis to a dataset of 249 offshoring experiences terminated with a relocation to the home country region we estimate the effects of different groups of survival determinants results highlight that contextual factors such as the industry the home country the host country and the size of the firm significantly affect the duration of offshoring experiences the likelihood of termination is in fact higher for the electronics and automotive industries for small firms for firms headquartered in europe and for offshoring to asia the analysis of the motivations for reshoring shows that quality issues experienced offshore emerge as the key factor giving rise to shorter offshore stays based on these empirical findings a set of testable propositions is developed in particular we conjecture that the likelihood of termination of offshore manufacturing and the return to the home country may be accelerated by technology based industries small firm sizes shrinking cost differentials and the psychic distance between home and host country the organizational archetypes and quality related motivations

increasing evidence of purchasing power parity over the current float we conduct unit root tests of real exchange rates with the united states dollar and the german mark as base currencies using samples of data which begin in 1973 and end between 1982 and 1996 we find that as the sample is extended the evidence of ppp strengthens with panel but not univariate methods because of the sharp rise and fall of the dollar in the early 1980s rejections of the unit root null do not monotonically increase with the sample size the evidence of ppp is uniformly stronger when the mark is used as the base currency

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

market frictions and real exchange rates abstract one explanation for the failure of purchasing power parity ppp is that market frictions impede trade allowing departures from ppp to grow quite large without precipitating goods arbitrage if this explanation is correct then other things equal large deviations from ppp should be less persistent than small differences this paper examines this prediction over the modern floating rate era the outcome is surprising between most countries large deviations from ppp appear to be at least as persistent as small deviations and perhaps even more so the exceptions are for some intra ec real exchange rates the implication is that market frictions alone do not explain the chimerical nature of ppp

u s dollar real exchange rates nonlinearity revisited abstract previous empirical work employing smooth transition autoregressive star models has found that u s dollar real exchange rates are nonlinear mean reverting processes we utilise tests developed from time varying smooth transition autoregressive tv star models to re examine dollar based rates these tests reveal that structural change is an important feature of the data in some cases there is support for both nonlinearity and structural change while in other cases there appears to be stronger support for structural change than for nonlinearity the results raise a number of interesting issues for future research

nominal exchange rate regimes and the real exchange rate abstract two assumptions about the real exchange rate are common in the literature on international finance 1 the real exchange rate is a random walk 2 the time series properties of the real exchange rate depend on the nominal exchange rate regime this paper presents evidence that indicates that the random walk behavior of the real exchange rate is only a characteristic of the post world war ii period moreover our findings also suggest that what is crucial to the real exchange rate behavior is the particular historical period rather than the nominal exchange rate arrangement

searching for nonlinearities in real exchange rates a recent innovation in modeling exchange rates has been the use of nonlinear techniques such as threshold autoregressive models and its smooth transition variants this paper investigates the smooth transition autoregressive star modeling strategy in an application to real exchange rates the key findings are as follows first using the methodology advocated by terasvirta 1994 we find evidence of nonlinear dynamics for several of the spot dollar real exchange rates using monthly data on five of the g7 countries however once estimated we find that the star specification is appropriate for only one of the three exchange rate series indicated to be an estar process moreover using simulations we show that the underlying methodology used to detect nonlinearities in the data exhibit substantial size biases which we attribute to influential observations we also investigate an alternative nonlinear specification and find that we can model the dollar sterling and the dollar lira real exchange rates better as an open loop tar process instead of a setar process

dynamic hedge ratio for stock index futures application of threshold vecm this study represents one of the first papers in stock index futures arbitrage literature to investigate the effects of arbitrage threshold on stock index futures hedging effectiveness by using threshold vector error correction model hereafter threshold vecm moreover in contrast to prior studies focusing on examining case studies involving mature stock markets this study not only adopts us s p 500 stock market as the sample but also adds an analysis of one emerging stock market hungarian bsi and examines the differences between them finally this investigation employs a rolling estimation process to examine the impact of arbitrage threshold behaviours on the setting of futures hedging ratio the empirical findings of this study are consistent with the following notions first arbitrage behaviour reduces co movement between futures and spot markets and increases the volatility of both futures and spot markets second this article denotes the outer regime of futures spot market for the case of hung

change in domestic network centrality uncertainty and the foreign divestment decisions of firms abstract we investigate the role of domestic interfirm networks for the foreign divestment decisions of firms we argue that firms foreign operations risk being divested when a firm becomes more central in its domestic network positive changes in firm centrality at home facilitate access to information about new business opportunities but they may also lead firms to consider reconfiguring their value chain activities and resources across locations the resulting opportunity costs of maintaining foreign operations could subsequently lead to their divestment moreover we argue that the positive association between an increase in firm centrality in the domestic network and foreign divestment is stronger under higher uncertainty as pursuing new business opportunities at home becomes more appealing we distinguish between firm specific uncertainty and domestic market uncertainty we test and get support for our hypotheses using foreign subsidiary data from u s firms in the ict industry

cointegration and tests of purchasing power parity nonstationarity in the levels of spot exchange rates and domestic and foreign price indices makes the use of conventional tests of the absolute version of purchasing power parity ppp inappropriate if ppp is true inter country commodity arbitrage ensures that deviations from a linear combination of spot exchange rates and domestic and foreign price levels should be stationary under these conditions exchange rates and price levels should form a cointegrated system we find the null hypothesis of no cointegration cannot be rejected for all five countries thus violating the long run absolute version of ppp

uncertainty and export performance evidence from 18 countries we study a sample of nine developed and nine developing countries to evaluate the questions of how foreign income uncertainty and real exchange rate rer uncertainty impact international trade and how those impacts vary according to stage of development rer uncertainty has a negative and significant impact on export growth for six of the nine less developed countries in our sample while it has an insignificant effect for a majority of the developed countries in both groups foreign income uncertainty has a more pervasively significant and frequently larger influence on trade than does rer uncertainty

testing purchasing power parity under the null hypothesis of co integration this paper analyzes monthly data on the exchange rates and price indices of the eleven major industrial countries over the modern period of floating exchange rates it presents tests that are based upon the null hypothesis of cointegration the paper finds evidence that most country pairs not involving north american currencies have exchange rates and price indices that are cointegrated it estimates the error correction representation for the series that are cointegrated and it shows that the dynamic adjustment of the relationship between exchange rates and prices is accomplished almost entirely in the market for foreign exchange copyright 1991 by royal economic society

a long run view of the european monetary system abstract this papaer analyzes the exchange rates and consumer price indices of six countries participating in the european monetary system ems during the entire period of floating exchange rates the analysis shows that most of these real exchange rates have unit roots even when one allows for the possibility of a structural break at the time of the advent of the ems further proces and exchange rates are not co integrated during the ems period the data suggest that the 12 realignments of the ems have not served fully too offset the member countries inflation differentials

the exchange rate exposure puzzle the long and the short of it the exchange rate exposure puzzle has remained robust to empirical scrutiny however evidence suggests the puzzle abates when longer horizons are considered this paper applies inference that is appropriate in a long horizon setting and finds this evidence is illusory

state dependent pricing and business cycle asymmetries we present a tractable dynamic general equilibrium model of state dependent pricing and study the response of output and prices to monetary policy shocks we find important non linearities in these responses for empirically relevant shocks this generates substantially different predictions from time dependent pricing we also find a distinct asymmetry with state dependent pricing prices respond more to positive shocks than they do to negative shocks this is due to a strategic linkage between firms in the incentive for price adjustment our state dependent model can account for business cycle asymmetries in output of the magnitude found in empirical studies

towards solving the ppp puzzle evidence from 113 countries several different approaches have been followed by researchers to test the validity of purchasing power parity ppp since the introduction of the unit root tests researchers have applied a battery of these tests to determine whether the real exchange rates are stationary if the answer is in the affirmative ppp is validated while application of the standard augmented dickey fuller test has not provided much support for ppp a test that incorporates nonlinearity in the rates has under both tests however the null of nonstationary is tested against the alternative of stationarity in this article when we switch the null with the alternative and apply kwiatkowski et al 1992 test we provide relatively more support for the theory getting closer and closer towards solving the ppp puzzle

divestment of foreign production operations this study investigates some determinants fo the divestment of foreign manufacturing operations by norwegian companies to date very few studies have taken a closer look at what might influence whether foreign subsidiaries are divested or not although foreign direct investment in principle represent long term commitments to foreign manufacturing operations divestments are in fact quite common this study shows that more than half of a sample of foreig subsidiaries woned by norwegian companies in 1982 wee divested within a period of ten years the empirical findings indicate that foreign divestment is inversely related to economic growth in the host country and that the propensity to divest is significantly higher for subsidiaries that had been acquired than for greenfield establishments also related horizontal subsidiaries are less likely to be divested than unrelated non horizontal subsidiaries

foreign and domestic divestment and investment decisions like or unlike the managerial literature on foreign investment and divestment is much less developed than the economic literature on foreign direct investment theory nevertheless surveyed with the purpose of better understanding foreign divestment decisions the research to date reveals some noticeable differences between investment and divestment divisions whether foreign or domestic and even more substantial differences between foreign divestment and domestic divestment decisions additional research however is clearly in order

menu costs and the long run output inflation trade off abstract in standard new keynesian models there exists an unlimited long run trade off between output and inflation but when we allow for an endogenous frequency of price adjustment this is replaced by an inverted u shaped relationship

purchasing power parity and unit root tests using panel data abstract this paper reports the results of unit root tests for real exchange rates using a panel framework this panel approach provides greatly improved power compared to conventional univariate time series unit root tests we obtain evidence supporting ppp over the recent flexible exchange rate period for g 6 and oecd countries we show explicitly that failure to find such evidence in previous research was due to the low power of the tests

a synthesis of foreign direct investment theories and theories of the multinational firm this paper first presents a taxonomy of the foreign direct investment theories following the market imperfections paradigm it then focuses on recent developments pertaining to the theory of the multinational firm specifically the appropriability internalization and diversification theories subsequently the multinational phenomenon is seen as the result of an international differentiation of activities and an intrafirm integration across national borders all this within a markets and hierarchies approach last the paper points to areas for future research

purchasing power parity as a long run relation dickey fuller and stock watson tests of purchasing power parity ppp as a long run proposition are provided within the cointegration framework proposed by granger since different countries use different weights to construct price indices the traditional constraint that the coefficients on the price indices should be unity in the log linear ppp relation is relaxed the absence of a general ppp relation cannot be rejected at most a ppp relation is indicated in five out of fifteen country pairs that are examined even if a long run ppp relation exists it is not found to be useful in predicting future nominal exchange rates which is consistent with efficient speculative markets

comparative analysis of the foreign investment evaluation practices by u s based manufacturing multinational companies a large sample of u s based manufacturing multinational companies were surveyed regarding their investment valuation practices it was found that a foreign direct manufacturing investment fdmi is motivated primarily by profit rather than the recently proposed behavioral considerations b the majority of companies practice project by project analysis of the simple accept reject type rather than the comparative project analysis advocated by financial analysts c most of the companies utilized criteria for single investments cash flows and cost of capital that were in general agreement with the analytical literature d companies were concerned more with business risk than currency and political risks moreover all three types of risk were evaluated subjectively and accounted through adjustments in the required rates of return rather than the cash flows of the fdmi as specified in financial research e analysis of demographic and behavioral variables for possible relationships to fdmi evaluation practices yielded interesting but variable specific results the questionnaires were mailed in may 1979 and the personal interviews were conducted during december 1979 and the first six months of 1980

was it real the exchange rate interest differential relation over the modern floating rate period in this paper we explore the relationship between real exchange rates and real interest rate differentials in the united states germany japan and the united kingdom contrary to theories based on the joint hypothesis that domestic prices are sticky and monetary disturbances are predominant we find little evidence of a stable relationship between real interest rates and real exchange rates we consider both in sample and out of sample tests one hypothesis that is consistent with our findings is that real disturbances such as productivity shocks may be a major source of exchange rate volatility this paper investigates the empirical relationship between major currency real exchange rates and real interest rates over the modern post march 1973 flexible rate experience the exchange rates examined here include the dollar mark dollar yen and dollar pound rates our two major findings are as follows first the data do not indicate a strong correspondence between real interest rate differentials short term or long term and real exchange rates this finding appears to conflict with the predictions of most monetary and portfolio balance models of exchange rate determination though the conflict can be substantially reconciled if aggregate disturbances are primarily real in nature i e changes in productivity tastes etc it is true that in many cases the sign of the estimated exchange rate interest rate differential relationship is consistent with the possible predominance of financial market disturbances but the relationship is not stable enough to be statistically significant second although one does find some evidence of a unit root in both real exchange rates and long term but not shortterm real interest differentials these two series do not appear to be linearly cointegrated hence the nonstationarity or near nonstationarity in the two series cannot be attributed to the same factor in section i we briefly describe a class of small scale monetary models of exchange rate determination the importance of this class of models for empirical work derives from its strong predictions about how the exchange rate will move

measuring the persistence of deviations from purchasing power parity with a fractionally integrated star model abstract empirically elements of both fractional long memory and threshold non linearity are present in the real exchange rates of the g 7 countries against the us notably in the eu countries estimated half lives of deviations from ppp using median unbiased corrections to conventional linear autoregressive models corroborate existing evidence related to the ppp paradox as half lives range from at least four years to an infinite number of years in contrast for each eu country accounting for threshold non linearity results in estimated half lives that can be less than three years even with the allowance for fractional long memory

staggered price setting with endogenous frequency of adjustment abstract a model of staggered price setting in which the frequency of price changes is endogenous is presented

foreignness and exit over the life cycle of firms received wisdom indicates that owing to a liability of foreignness foreign firms exit with greater likelihood than do comparable domestic firms and that the difference attenuates as firms age and overcome the liability we posit that foreign firms are also intrinsically more volatile and footloose than domestic ones and that this leads to an increasing divergence between the exit rates of foreign and domestic firms empirically we find that the difference between exit rates of foreign firms and domestic firms increases with age as exit of foreign firms increases with age while that of purely domestic firms decreases exit rates of domestic based multinationals do not change significantly with age they are between those of foreign and purely domestic firms but are closer to the latter this suggests that the footlooseness observed for foreign firms is due to foreignness more than to multinationality

goods prices and exchange rates what have we learned import prices typically change by a smaller proportion than the exchange rate between the exporting and importing country recent research indicates that common currency relative prices for similar goods exported to different markets are highly correlated with exchange rates between those markets this evidence suggests that incomplete pass through is a consequence of third degree price discrimination while distance matters for market segmentation borders have independent effects the source of the border effect has not been clearly identified furthermore there is little evidence yet to suggest substantial market power is implied by the observed price discrimination

nonlinear mean reversion in real exchange rates abstract this paper modifies a unit root test procedure in the nonlinear star framework recently advanced by kapetanios et al journal of econometrics 2001 in press using a detrending methodology suggested by schmidt and phillips oxford bulletin of economics and statistics 54 1992 257 we derive an alternative unit root test and apply it to the bilateral real exchange rates for the g7 countries we find that the use of our test is able to uncover evidence of nonlinear mean reversion for most cases whereas the standard dickey fuller test based on the linear model cannot

searching for evidence of long run ppp from a post bretton woods panel separating the wheat from the chaff abstract this paper reexamines the issue of long run ppp using multiple panel tests in the framework of confirmatory analysis application of six panel tests under competing null hypotheses to the real exchange rates of 21 industrial countries yields seemingly contradictory evidence on the parity during the post bretton woods period regardless of numeraire currency four i 1 panel tests unanimously reject the null hypothesis in favor of long run ppp whereas two i 0 panel tests lend little support to the parity at conventional significance levels confirmatory analysis suggests that this puzzling result can be explained either by nonlinear dynamics of the real exchange rates or by a mixture of i 0 and i 1 series in the panel monte carlo experiments indicate that potential mix of i 0 and i 1 series is more relevant to the empirical finding the use of a sequential classification method sorts out six real exchange rates which exhibit most persistent deviations from long run equilibrium systematic behavior of these series can be characterized better by country specific factors than by observable macroeconomic variables

searching for stationarity purchasing power parity under the current float abstract using panel data methods we investigate long run purchasing power parity by testing for unit roots in real exchange rates of industrial countries under the current float the evidence against the unit root hypothesis is stronger for larger than for smaller panels for monthly than for quarterly data and when the german mark rather than the united states dollar is used as the base currency while we find that accounting for serial correlation considerably weakens the evidence against the unit root null the results as a whole are consistent with long run purchasing power parity

how well does nonlinear mean reversion solve the ppp puzzle abstract this paper addresses the degree to which models which exhibit nonlinear mean reversion nmr present a resolution to the purchasing power parity puzzle this paper develops a method of estimating a representative distribution of half lives which is based upon the observed distribution of shocks in a given time series rather than choosing shock sizes arbitrarily which is the current practice in the literature this approach is implemented with data on five real exchange rates the empirical analysis shows that half lives shorter than the consensus are observed frequently enough to support the proposition that nmr is a solution to the ppp puzzle

an empirical examination of long run purchasing power parity using cointegration techniques this paper presents an empirical analysis of long run purchasing power parity ppp for five major exchange rates using recently developed econometric techniques on the cointegration of economic time series our empirical results are extremely unfavourable to the ppp hypothesis as a long run equilibrium condition even with an allowance made for measurement error and or tranportation costs in particular we are unable to reject the hypothesis of non cointegration of the exchange rate and relative prices for any of the countries concerned far from finding a stable long run proportionality between exchange rates and relative prices our results therefore suggest that they tend to drift apart without bound

testing symmetry and proportionality in ppp a panel data approach purchasing power parity ppp is a proposition equating the nominal exchange rate to the ratio of the domestic to foreign price levels this article employs bayesian panel data methods to test for ppp in particular the implied symmetry and proportionality conditions using a dataset of all the organization for economic cooperation and development member countries in the post bretton woods era i do not find support for symmetry and proportionality in ppp over time and across countries

temporal aggregation of an estar process some implications for purchasing power parity adjustment nonlinear models of deviations from ppp have recently provided an important theoretically well motivated contribution to the ppp puzzle most of these studies use temporally aggregated data to empirically estimate the nonlinear models as noted by taylor 2001 if the true dgp is nonlinear the temporally aggregated data could exhibit misleading properties regarding the adjustment speeds we examine the effects of different levels of temporal aggregation on estimates of estar models of real exchange rates our monte carlo results show that temporal aggregation does not imply the disappearance of nonlinearity and that adjustment speeds are significantly slower in temporally aggregated data than in the true dgp furthermore the autoregressive structure of some monthly estar estimates found in the literature is suggestive that adjustment speeds are even faster than implied by the monthly estimates

the overvaluation of purchasing power parity abstract recent panel studies of purchasing power parity have reported strong evidence of mean reversion in real exchange rates however these studies fail to control for cross sectional dependence in the data this failure has dramatic consequences raising the significance level of tests with a nominal size of 5 percent to as much as 50 percent it is shown in this paper that controlling for cross sectional dependence no evidence against the random walk null can be found in panels of up to 64 real exchange rates this finding cannot be attributed to low power as there is ample power in panels of this size to reject the unit root null

does ppp hold in african countries further evidence based on a highly dynamic non linear logistic unit root test with a view to investigating whether the purchasing power parity ppp theory holds true for selected african countries during the january 1980 december 2003 period we employ a rigorous highly dynamic non linear logistic unit root test as first advanced by leybourne et al 1998 which is considerably more powerful than those tests traditionally used compared with the rejection of the null of the unit root process for only one of the 22 countries under study when we use the traditional adf pp kpss np and the df gls unit root tests with the leybourne et al 1998 test we strongly reject the null of the unit root process for a surprising six of the 22 countries these empirical results clearly indicate that ppp holds true for these six countries namely the central african republic the cote d ivoire kenya madagascar uganda and lesotho

long run purchasing power parity with asymmetric adjustment further evidence from african countries this study applies threshold cointegration test advanced by enders and siklos 2001 to investigate the properties of asymmetric adjustment in long run purchasing power parity ppp in 22 selected african countries during the period of january 1980 to december 2003 although there is evidence of long run ppp for most african countries the adjustment mechanism is asymmetric these results have particularly important policy implications for african countries

the inadequacy of linear autoregressive model for real exchange rates empirical evidence from asian economies utilizing the formal linearity test of luukkonen saikkonen and terasvirta biometrika 75 491 499 1998 as diagnostic tool the empirical finding suggests that the linear autoregressive ar model is inadequate in describing the real exchange rates behaviour of 11 asian economies it is noted that the conventional battery of diagnostic tests is capable of identifying the inadequacy of the linear model in only three of these series moreover the linearity nature of this behaviour has been formally rejected in favour of the non linear smooth transition autoregressive star model the finding of non linearity in the data generating process of these real exchange rates warrants that the use of linear framework in empirical modelling and statistical testing procedures in the field of exchange rates may lead to an inappropriate policy conclusions

exchange rate pass through and inflation a nonlinear time series analysis abstract this paper investigates the relationship between the exchange rate pass through erpt and inflation by estimating a nonlinear time series model based on a simple theoretical model of erpt determination we show that the dynamics of erpt can be well approximated by a class of smooth transition autoregressive star models using the past inflation rate as a transition variable we employ several u shaped transition functions in the estimation of the time varying erpt to us domestic prices the estimation result suggests that declines in the erpt during the 1980s and 1990s are associated with lowered inflation

nonlinearities in real exchange rate determination do african exchange rates follow a random walk in this article we aim at modelling the long run behaviour of the real effective exchange rates reer for a pool of african countries not much attention has been paid to this group of countries in particular to the existence of nonlinearities in the long run path of such a variable controlling for two sources of nonlinearities i e asymmetric adjustment to equilibrium and nonlinear deterministic trends allows us to gain some insight about the behaviour of the african reer we find that these sources of nonlinearities help us to explain the apparent unit root behaviour found applying linear unit root tests for most of the countries

can exchange rates forecast commodity prices we show that commodity currency exchange rates have surprisingly robust power in predicting global commodity prices both in sample and out of sample and against a variety of alternative benchmarks this result is of particular interest to policy makers given the lack of deep forward markets in many individual commodities and broad aggregate commodity indices in particular we also explore the reverse relationship commodity prices forecasting exchange rates but find it to be notably less robust we offer a theoretical resolution based on the fact that exchange rates are strongly forward looking whereas commodity price fluctuations are typically more sensitive to short term demand imbalances

foreign and domestic divestments evidence on valuation effects of plant closings this study examines the valuation consequences of domestic and foreign divestments by comparing the stock price reaction to announcements of domestic plant closings and foreign plant closings a domestic plant closing could indicate firm wide problems and impending firm deterioration a foreign plant may serve to exploit arbitrage opportunities specific to that plant location closing a foreign plant need not signify firm wide problems our comparison of stated reasons for closings supports these propositions therefore foreign plant closing announcements should produce a smaller stock price decline that domestic plant closing announcements empirical results indicate a significant negative stock price reaction for domestic plant closings and an insignificant negative stock price reaction for foreign plant closings differences in stock price reaction remain after controlling for firm specific factors

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

real exchange rates under the gold standard purchasing power parity is one of the most important equilibrium conditions in international macroeconomics empirically it is also one of the most hotly contested numerous recent studies for example have sought to determine the validity of purchasing power parity using data from the post bretton woods float and have reached different conclusions we assert that most such studies are flawed for two reasons first the post 1973 data contain by definition only a very limited amount of the low frequency information relevant for examination of long run parity second the dynamic econometric techniques used to model deviations from parity are typically quite crude with respect to admissible low frequency dynamics both deficiencies are rectified in the present paper with dramatic results we construct a new data set of 16 real exchange rates covering more than a century of the classic gold standard period and we study deviations from parity using long memory models that allow for subtle forms of mean

explaining the exchange rate pass through in different prices abstract this paper examines the performance of a variety of new open economy macroeconomic models in explaining the exchange rate pass through in a wide range of prices quantitative versions of different models are used to derive the dynamic response of various prices to an exchange rate shock predicted responses are compared with the evidence based on var models to examine how well different models fit the data the results show that the best fitting model incorporates a number of features highlighted by different strands of the literature sticky prices sticky wages distribution costs and a combination of local lcp and producer currency pricing pcp

deviations from purchasing power parity under different exchange rate regimes do they revert and if so how abstract we propose an empirical model for deviations from long run purchasing power parity ppp that simultaneously accounts for three key features i adjustment toward ppp may occur via nominal exchange rates and relative prices at different speeds ii different exchange rate regimes may generate regime shifts in the structural dynamics of ppp deviations iii nonlinear reversion toward ppp in response to shocks this empirical framework encompasses and synthesizes much previous empirical research using over a century of data for the g5 countries we provide evidence that long run ppp holds the relative importance of nominal exchange rates and prices in restoring ppp varies over time and across different exchange rate regimes and reversion to ppp occurs nonlinearly at a speed that is fairly consistent with the nominal rigidities suggested by conventional open economy models

quantile unit root test and ppp evidence from 23 oecd countries abstractapplication of six different univariate unit root tests to real effective exchange rates of 23 oecd countries supports their stationarity or purchasing power parity theory ppp only in five countries a result consistent with previous research that is known as ppp puzzle however descriptive statistics of each effective rate reveals a clear sign of non normal distribution to account for this we use quantile unit root test which allows impact of different shocks to be realized at different quantiles when we applied this new test to the same rates number of countries in which ppp is supported increased to 16 apparently incorporating effects of shocks improves testing efficiency and provides more support for the ppp and reduces the severity of the puzzle

using survey data to resolve the exchange risk exposure puzzle evidence from u s multinational firms while in previous literature foreign currency exposure is estimated to be surprisingly small and insignificant we question in this paper the rationality assumption and show that the traditional use of realized exchange rate changes to approximate unexpected currency shocks leads to a strong underestimation of the influence that exchange rates play in determining firm valuations in light of a unique survey data base of individual exchange rate expectations we distinguish between realized and unexpected foreign currency movements and find that half of our sample of 935 u s firms with real operations in foreign countries is significantly exposed to unexpected exchange rate movements in line with previously reported results foreign exchange risk exposure is found to become increasingly perceptible when the return horizon is lengthened the difference between the exposure to realized versus unexpected exchange rate movements is however decreasing when lengthening the horizon suggesting that the more market participants disagree about the future path of currency values the less investors and or managers are likely to use the publicly available forecasts in their pricing and hedging decisions

transactions costs and nonlinear adjustment in real exchange rates an empirical investigation eolquilibrium models of real exchange rate determination in the presence of transactions costs imply a nonlinear adjustment process toward purchasing power parity ppp conventional cointegration tests which ignore the effect of transactions costs may be biased against the long run ppp hypothesis our results using both monthly data for the interwar period and annual data spanning two centuries clearly reject the linear framework in favor of an exponential smooth transition autoregressive process the systematic pattern in the estimates of the nonlinear models provides strong evidence of mean reverting behavior for ppp deviations and helps explain the mixed results of previous studies

money demand function estimation by nonlinear cointegration conventionally the money demand function is estimated using a regression of the logarithm of money demand on either the interest rate or the logarithm of the interest rate this equation is presumed to be a cointegrating regression in this paper we aim to combine the logarithmic specification which models the liquidity trap better than a linear model with the assumption that the interest rate itself is an integrated process the proposed technique is robust to serial correlation in the errors for the usa our new technique results in larger coefficient estimates than previous research suggested and produces superior out of sample prediction copyright 2007 john wiley sons ltd

foreign subsidiary and parents roles during strategic investment and divestment decisions empirical research is scarce to answer the concerns of governments unions and public opinion at large concerning how multinationals make decisions to restructure their international strategic portfolio or close plants overseas to ensure long run competitiveness based on three in depth analyses of different types of restructing decisions the author concludes that the foreign subsidiaries seem to carry most of the decisionmaking effort for their own plant closures while for strategic portfolio readjustments during which they change owners they are not consulted

testing long run purchasing power parity under exchange rate targeting abstract the present paper exploits the idea that empirical estimates of the long run ppp relationship may compound two distinct influences coming from the behavior of market participants and policy makers when the latter are targeting the exchange rate this tends to bias tests of long run ppp against its acceptance the validity of the theoretical arguments is assessed by drawing on the experience of two european union countries greece and france for the post bretton woods period estimation biases due to the omission of policy effects are found to be significant only in the case of greece for france our test results provide evidence bearing on the effectiveness of the competitive disinflation strategy pursued by the french authorities

the law of one price evidence from the transitional economy of china abstract this paper applies the recently developed econometric methods of panel unit root tests and nonlinear mean reversion to investigate price convergence in china the largest transitional economy in the world we find that prices did converge to the law of one price in china for an overwhelming majority of goods and services based on a large panel data set the finding sheds light on the extent of the market economy in china and casts doubt on young s proposition that the economic reform has led to the fragmentation of chinese domestic markets
