This article investigates the time-series properties of 13 Asian real exchange rates (RERs) vis-à-vis the US dollar. The half-life point estimates drawn from the local-persistent model are all less than 2 years, with a finite upper bound. There is no evidence to indicate that the Asian financial crisis has altered the speed of the purchasing power parity (PPP) adjustments. We find that the persistence of RERs over the last three decades remains unchanged in majority of the cases. Given the fairly rapid speed of adjustments and their corresponding confidence intervals, we conclude that the PPP puzzle does not exist in these countries. 相似文献

This paper revisits the nexus between real effective exchange rate (REER) and total factor productivity (TFP) by controlling for trade openness, financial development and natural resources rents. We use a sample of 60 high‐income and upper‐middle income countries over the period 1995–2015 and employ the GMM estimation framework. Our results advance the empirical knowledge on the drivers of REER by providing robust evidence that the impact of TFP is not uniform across different country clusters. We find that in high‐income countries, increasing productivity causes the REER to depreciate hence becoming more trade competitive while the opposite is true for upper‐middle income countries. Furthermore, financial development and natural resources rents have no meaningful impact in the case of upper‐middle income countries but retain a significant effect in high‐income countries. Trade openness plays a key role in explaining the variation in REER in both country clusters. 相似文献

This article examines the long-run Purchasing Power Parity (PPP) hypothesis for 12 Latin American Real Effective Exchange Rates (REERs) using fractional integration techniques. The empirical results, applying parametric approaches, provide evidence of mean reversion in the REERs in the cases of Nicaragua, Belize, Costa Rica, Guyana and Paraguay and lack of it for the remaining seven countries. Employing semiparametric methods, the evidence of mean reversion covers the following countries: Belize, the Dominican Republic, Ecuador and Mexico. Thus, only for Belize and Guyana do we obtain consistent evidence of mean reversion in the real exchange rates. At the other extreme, lack of mean reversion, and thus, lack of PPP, is obtained with both methods in Bolivia, Brazil, Colombia and Venezuela. For the remaining six countries, the results are ambiguous. The results for the PPP theory in Belize and Guyana may show the importance of promoting policies based on exchange rate flexibility and economic liberalization to reach a long-run stability scenario that leads to greater international competitiveness and lower external vulnerability. 相似文献

We use data from the National Longitudinal Survey of Adolescent Health (Add Health) to study how sociability and adolescent alcohol use impact personal income as a young adult. We find that factors which enhance not only individual sociability but also social interaction at the community level are positively linked to future earnings of adolescents. Adolescents whose friends and friends of friends have greater sociability reap long-term labour market rewards into adulthood. After adjusting for individual and community sociability, the effect of teenage alcohol consumption on labour market earnings as young adults is reduced. Our results suggest that earnings premiums associated with adolescent alcohol consumption may be partially explained by social network dynamics. 相似文献

The present paper discusses the stochastic stationarity of New Zealand exchange rates in light of new time series methods and new tests. The question of whether the real exchange rates have a unit root or are mean reverting is set in the general framework of fractionally integrated models. The estimates sustain the claim that New Zealand real exchange series are not stationary. However, it is shown that nonstationarity is compatible with parity reversion in the framework of fractional unit-root models. 相似文献

This paper develops a recursive dynamic computable general equilibrium (DCGE) model to evaluate sources of accelerated growth and structural transformation. It goes beyond stylized and aggregate general equilibrium models by examining country-specific growth options to reach middle income country (MIC) status. We first examine a set of countries that have successfully transformed their economies to inform model and scenario building. We then simulate potentials and trade-offs of selected sector- and factor-specific growth paths for Ghana. Results show that no individual sector's growth acceleration is sufficient for Ghana to reach MIC status by 2015. Manufacturing growth is constrained by its high dependency on agricultural inputs indicating the need for diversification. Services can support rather than drive economy-wide growth. Agriculture must remain the mainstay of economy-wide growth. While this will delay structural change in sectoral composition, it demonstrates that emphasizing agriculture is a viable option for some countries to reach MIC status. 相似文献

The theoretical literature on exchange rate behaviour in target zones predicts that the exchange rate would be mean reverting. This article empirically investigates this theoretical prediction in the case of the German mark bilateral exchange rates. Using a recently developed unit root test, this article provides evidence that is generally negative to the idea of mean reversion. It shows that all bilateral exchange rates under investigation appear to be unit root processes with the exception of the Dutch guilder/German mark rate. 相似文献

In this article, we examine the degree of persistence in monthly real exchange rate of six East Asian countries in relation to their two major trading partners, the United States and Japan, to study the validity of PPP for the 1976:01–2009:03 period. To investigate the persistency in real exchange rate series, we use sum of the autoregressive (AR) coefficients and the confidence interval for it using grid-bootstrap procedure recently developed by Hansen (1999). We have two findings: first, we find evidence for high persistency in real exchange rate in terms of the Japanese yen for five countries and for four countries in terms of the US dollar the for the full and pre-crisis sample periods. Second, for the post-crisis period, the presence of low persistency in real exchange rate supports PPP for three countries in terms of the Japanese yen and five countries in terms of the US dollar. These findings indicate that real exchange rate series of five East Asian countries are mean-revert based on their exchange rate policies and East Asian countries can form a currency union. 相似文献

This paper examines whether inflation targeting (IT) influences purchasing power parity (PPP) by a bias correction approach under cross-sectional dependence. The recursive mean adjustment (RMA) method proposed by So and Shin (1999) and Shin and So (2001) is employed to correct a downward bias in half-life estimates of real exchange rates. More importantly, the empirical results show that IT lowers variability of real exchange rates and plays an important role in providing favorable evidence for long-run PPP. 相似文献

This paper provides new evidence on the purchasing power parity (PPP) hypothesis in six East Asian countries. Based on nonlinear unit root tests, we discovered that the results are broadly consistent with the fact that real exchange rates (RERs) follow a nonlinear mean reversion process. We presented new evidence that the adjustment towards the PPP parity is asymmetric (LSTAR process) above and below the equilibrium value in all but one case — the Malaysian ringgit (MYR). The empirical results suggest that it is important that the conventional tests of PPP be amended to take account of asymmetries in the adjustment process in RERs. 相似文献

Measuring deviations from purchasing power parity has been the subject of extensive investigation. The most common practice in empirical research for measuring real exchange rate persistence is to estimate univariate autoregressive (AR) time series models and calculate the half-life, defined as the number of periods for a unit shock to a time series to decay by 50%. In the presence of structural change, there are two potential biases in the parameter estimates of AR models: (1) a downward small sample median-bias and (2) an upward bias, which occurs when structural change is present and ignored. We conduct a variety of Monte Carlo simulations and demonstrate that the existence of structural change causes a substantial increase in the small sample bias documented in Andrews (1993). We then propose an extension of median-unbiased estimation, which explicitly accounts for structural change, and apply these methods to estimate half-lives of several long-horizon real exchange rates analysed by Lothian and Taylor (1996) and Taylor (2002). The upward bias from neglecting structural change dominates the downward median-bias for these real exchange rates. When structural change is present and accounted for, the median-unbiased half-lives towards a changing mean decrease and the confidence intervals tighten. 相似文献

In this paper, we explore the determinants of black market (BM) exchange rates in India using annual data from 1955–1994
and integration and cointegration analysis. Two important factors, namely the import capacity of official foreign exchange
reserves and restrictions on international trade, have largely been ignored as determinants of BM rates. We stress the importance
of these two factors and incorporate them, with others more familiar in the literature, in our theoretical and empirical model
for BM rates in India. Our empirical findings show that a low level of official foreign exchange reserves negatively and a
high level of trade restrictions positively affect BM rates. We show that the flexible Bretton Woods exchange rate policies
for India in 1973 have a negative impact on BM rates. The results also reveal that interest rate policies positively affect
BM rates. Thus, our empirical model lends support to the trade and monetary approaches to BM rates and hence, trade restrictions
with excess money supply should be removed to eliminate the BMs for forex in India.

This paper investigates long-run Purchasing Power Parity (PPP) between the US and Mexico. We use a panel of disaggregated price data between the US and Mexico with a long time series to look at two types of aggregation bias. The first is examined in Imbs et al. — which we refer to as estimator aggregation bias — and the second is put forth by Broda and Weinstein — hereafter, data aggregation bias. The findings indicate substantial estimator aggregation bias and data aggregation bias. Although estimates using aggregate data and imposing homogeneous coefficients provide little evidence of PPP, findings with disaggregated data and heterogeneous coefficient estimators offer strong support. The results also suggest the presence of small-sample bias as examined in Chen and Engel, but with little effect on the qualitative results. Tradable goods and non-tradable goods show little distinction in convergence rates. Estimated half-lives are lower under flexible than fixed exchange rates and indicate rapid convergence during the Mexican peso crisis. 相似文献

This paper investigates nonlinearities in the dynamics of real exchange rates. We use Monte Carlo simulations to establish the size properties of the Teräsvirta-Anderson test, when the dynamics of the real exchange rate is influenced by an exogenous process. In addition, we show that a modified nonlinearity test, which includes additional right-hand-side variables, performs much better than the original in both Monte Carlo exercises and in the actual data on 1431 bilateral real exchange rate series. Finally, we investigate the dynamics of the real exchange rate for both developed and developing countries using the modified test for the recent floating period. In general, the results find a greater incidence of nonlinear dynamics for developing country real exchange rates. 相似文献

We explore whether a fiscal devaluation, that is, a reduction in employers’ social security contributions and an increase in value added tax, affects two indicators of bilateral real exchange rates in the euro area: one based on unit labor costs, and another based on consumer prices. We find that, in the short term, cuts in employers’ contributions depreciate real exchange rates based on unit labor costs, while value added tax hikes appreciate real exchange rates based on consumer prices. In the long run, a value added tax increase also appreciates the real exchange rates based on unit labor costs. 相似文献

This article examines whether the purchasing power parity (PPP) theory holds or not for the economies in different developing regions located in Africa, Asia and Latin America. In order to investigate this issue, a nonlinear panel unit root test is used to determine if some or all of the real exchange rates in a panel follow a stationary exponential smooth transition autoregressive process. By applying the nonlinear panel unit root test, our results demonstrate an empirical support for the theory of PPP for the economies in developing regions. 相似文献

Although the real exchange rate-real interest rate (RERI) relationship is central to most open economy macroeconomic models, empirical support for the relationship is generally found to be rather weak. In this paper we re-investigate the RERI relationship using bilateral US real exchange rate data spanning the period 1978-2007. Instead of testing one particular model, we build on Campbell and Shiller [1987. Cointegration tests of present-value models. Journal of Political Economy 95, 1062-1088] to propose a metric of the economic significance of the relationship. Our empirical results provide robust evidence that the RERI link is economically significant and that the real interest rate differential is a reasonable approximation of the expected rate of depreciation over longer horizons. 相似文献

ABSTRACTThe literature on real exchange rate effects on the labour market is dominated by short-run analysis showing that there is heterogeneity in the responses of firms or industries to a real exchange rate shock. Analysing data on Canadian manufacturing industries, I conclude that there is a common long-run equilibrium across all manufacturing industries controlling for their openness to trade after varying adjustments to a real exchange rate shock have taken place. This conclusion is important from the perspective of policy making because it helps to form expectations about the effects of a real exchange rate movement on the labour market. The results suggest that real appreciation leads to economically significant reductions in employment in manufacturing in the long run. Real wages decrease in industries that are highly engaged in international trade and somewhat increase in industries that are relatively closed to international trade. Both employment and real wages converge quickly to the long-run equilibrium. 相似文献

This article examines the impact of stock market news on the foreign exchange markets of USA, Canada and UK, employing an innovative extension of the asymmetric threshold model of Apergis and Miller (2006). Under this framework we can disentangle the reaction of foreign exchange market to bad or good news and small or large news of stock returns. Our comprehensive daily data-set spans the period from January 1990 to June 2014. Using a cointegration and error correction model, we document the existence of a causal relationship between stock market and foreign exchange markets. Most interestingly, our results derived from the asymmetric threshold model confirm that the relationship between stock and foreign exchange markets is sensitive to short-term good or bad news and short-term small or large news. Our findings entail significant implications for policymakers, governments, risk managers and international investors. 相似文献
