Bivariate cointegration among European monetary system exchange rates

In past research on the long-run behaviour of exchange rates the possibility of cointegration among spot rates has been rejected. This rejection is surprising as some exchange rates are bound by official agreements to comove over time. The European Monetary System (EMS) is an example of such an officially coordinating system. In this paper we extend past research by focusing on only EMS rates and use potentially more powerful cointegration tests to show that EMS rates are cointegrated.     

Excess volatility of real exchange rates in the EMS: some evidence from structural VARs

This paper argues that the effectiveness of the exchange rate mechanism (ERM) of the European Monetary System (EMS) should be gauged by its impact on the monetary component of real exchange rate variability. Nominal and real shocks are separated using a bivariate structural VAR applied to real exchange rate data of the six original member countries participating in the ERM and a control group consisting of Britain and the United States. The findings suggest that monetary shocks have been an important source of real exchange rate variability and that the ERM has been successful in reducing the incidence of monetary shocks across its member countries prior to the EMS currency crises of 1992–93, while being less successful thereafter.     

The spot and forward exchange rates: some empirical evidence of Singapore

This paper studies the foreign exchange market of Singapore. It examines the hypotheses that the spot exchange rate follows a random walk and that the exoected value of the future spot rate is the current forward rate. Using various powerful tests that have been developed recently in the economietric literature, we reject the two hypotheses convincingly.     

Re-examining the exchange rate pass-through into import prices using non-linear estimation techniques: Threshold cointegration

We document a significant threshold cointegrating relationship among effective nominal exchange rates and import prices. Using quarterly data for five industries of 16 OECD countries, we find that the degree of pass-through improves dramatically from the 50% average documented in the literature once threshold effects are recognized. The results of our threshold cointegration model show that import prices respond faster and by a larger extent to nominal exchange rate shocks than is the case for more conventional models. These findings give empirical support to the hypothesis that an equilibrium rate of pass-through exists (e.g. [Bacchetta, P., & Van Wincoop, E. (2005). A Theory of the currency denomination of international trade, Journal of International Economics 67, 295–319; Devereux, M., Engel, C., & Storgaard, P. (2004). Endogenous exchange rate pass-through when nominal prices are set in advance, Journal of International Economics 63(2), 263–291]).     

Real exchange rates and real interest rates once again: a multivariate panel cointegration analysis

This paper employs multivariate panel cointegration techniques to re-examine the empirical relationship between bilateral real exchange rates and real interest rates. The results from a panel of 1470 quarterly observations on Canada, France, Germany, Italy, Japan, UK, and USA over the period 1977 to 1994 indicate the absence of any long-run relationship between the two variables.     

Real exchange rates and job flows: evidence from Turkey

This study investigates the effects of the real exchange rate on job flows in Turkish manufacturing industries between 2006 and 2015 using data at the four-digit NACE Revision 2 level. Using dynamic panel data models, we find that a real appreciation increases gross and net job creation rates, and that the effect of appreciation is magnified as the exposure to international competitiveness of industries increases. We think that this is because Turkish manufacturing firms import a greater share of their inputs compared to the firms in developed countries. Hence, an appreciation creates more jobs because lower imported input costs enable firms to outcompete foreign producers.     

GARCH inadequacy for modelling exchange rates: empirical evidence from Latin America

This article checks for the adequacy of using GARCH models in exchange rate series. Using the Hinich portmanteau bicorrelation test, we find that a GARCH formulation or any of its variants fails to capture the data generating process of the main Latin American exchange rates. Our results highlight the potential of having misleading public policy when estimates are based in GARCH types of models. This article also complements recent similar findings encountered in European and Asian economies.     

Wagner's hypothesis: evidence from Kuwait using cointegration tests

This paper investigates the relationship between public expenditure and a number of socioeconomic variables, including the level of income, in Kuwait. A general form of the public expenditure function is formulated and recent developments in time series econometrics, including unit roots and cointegration tests, and an error-correction model are used. Given the characteristics of the economy, alternative measures for each variables are used. The analysis in the paper is based on time-series data covering the period from 1969/70 to 1994/95. In general, the findings lend little support to the existence of long-run equilibrium relationship between public expenditure and the socioeconomic variables, and the evidence does not lend support to the validity of Wagner's law in Kuwait.     

The demand for money and the real exchange rate misalignments in emerging European countries: A nonlinear approach

This paper investigates the extent to which domestic and foreign money balances in emerging European countries are influenced by foreign exchange considerations. A well-specified and stable relationship between real money demand and the exchange rate can be perceived as an important part of a successful monetary policy. This study examines the long-run determinants of real exchange rates (RERs) associated with the behavioral equilibrium exchange rate (BEER) approach and identifies currency misalignments in these countries. The misalignment is later used to test the nonlinear behavior of the demand for money. The results indicate that the RER misalignments have a significant impact on domestic money demand. When the currencies are overvalued, there is a reduction in domestic money demand, and when they are undervalued, there is an increase in domestic money demand. Furthermore, it can be concluded that overvaluation causes an increase in foreign money demand indicating a shift of preference from domestic to foreign currency.     

Nonlinearities in the real exchange rates: new evidence from developed and developing countries

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.     

Parity reversion in the Asian real exchange rates: new evidence from the local-persistent model

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.     

Dynamic forecasting of monetary exchange rate models: Evidence from cointegration

The Frenkel-Bilson and Dornbusch-Frankel monetary exchange rate models are used to estimate the out-of-sample forecasting performance for the U.S. dollar/Canadian dollar exchange rate. By using Johansen's multivariate cointegration, up to three cointegrating vectors were found between the exchange rate and macroeconomic fundamentals. This means that there is a long-run relationship between the exchange rate and economic fundamentals. Based on error correction models, two monetary models outperform the random walk model at the three-, six-, and 12-month forecasting horizons. Therefore, monetary exchange rate models are still useful in forecasting exchange rates.     

Genetic multi-model composite forecast for non-linear prediction of exchange rates

The existence of non-linear deterministic structures in the dynamics of exchange rates has already been amply demonstrated. In this paper, we attempt to exploit these non-linear structures employing forecasting techniques, such as Genetic Programming and Neural Networks, in the specific case of the Yen/US$ and Pound Sterling/US$ exchange rates. Forecasts obtained from genetic programming and neural networks are then genetically fused to verify whether synergy provides an improvement in the predictions. Our analysis considers both point predictions and the anticipating of either depreciations or appreciations.First version received: July 2003 / Final version received: June 2004We wish to thank Pacific Exchange Rate Service for providing us the data.     

The prevalence of hyperbolic discounting: some European evidence

Experimental matching data are used from the 2000 Bank of Italy Survey of Household Income and Wealth (SHIW) and the 2000 wave of the Center for Economic Research (CentER) Savings Survey at Tilburg University to compare the relative frequencies of hyperbolic and exponential discounters. Among 3200 Italian respondents and 1400 Dutch respondents, less than a quarter exhibited hyperbolic discounting. This finding is both statistically significant and robust with respect to various assumptions regarding utility; moreover, it holds across a wide variety of economic, social and demographic characteristics. The youngest, poorest, most urban and least educated individuals are the most likely to be hyperbolic discounters. In addition, it is found that hyperbolic discounters accumulate less wealth and are somewhat less likely than exponential discounters to utilize commitment devices to constrain their future choices.     

Multivariate cointegration and causality tests of Wagner's hypothesis: evidence from the UK

The purpose of this paper is to examine the issue of omitted variables in testing the long run validity of Wagner's hypothesis. Using UK data for the period 1948 to 1997, this paper first investigates the secular relationship between public spending and economic development in a bivariate system. In all cases considered, our bivariate cointegration tests indicate the absence of a long run equilibrium condition. However, the introduction of a third variable (money supply) re-establishes a cointegrating relationship between public expenditure and economic development variables. In addition, the results of the Granger's multivariate causality test indicate a unidirectional causality from income and money supply to public spending in the long run, thus providing support for Wagner's hypothesis.     

Chaos in East European black market exchange rates

In this paper we test for deterministic chaos in seven East European black market exchange rates, using Koedijk and Kool's (1992, Journal of Business and Economic Statistics, 10, 83-96) monthly data from January 1955 through May 1990. In doing so we use three (non-parametric) inference methods, the BDS (Brocket al., 1996, Econometric Reviews, 15, 197-235) test for whiteness, the Lyapunov exponent estimator of Nychkaet al.(1992, Journal of the Royal Statistical Society, 12, 135-136) as well as the Lyapunov exponent estimator of Gencay and Dechert (1992, Physica D, 59, 142-157). We find some consistency in inference across methods, and we conclude, based on the Nychkaet al.(1992) estimator, that there is evidence consistent with a chaotic non-linear generation process in only two out of seven series.     

Effects of tariffs and real exchange rates on job reallocation: evidence from Latin America

Openness to international competition can lead to enhanced resource allocation in the end. While factor reallocation is essential if net benefits are to be derived from trade liberalization, the process generates costs both for transitioning workers and for employers undergoing personnel turnover. Net welfare gains depend on adjustment costs. Understanding of these issues has been hampered by data limitations. In this paper, we overcome some of these limitations by using new, harmonized measures on job creation and destruction for a number of countries in Latin America. We use these new series to investigate the impact of the removal of protectionism on net employment and gross job reallocation in Latin America. We find a robust pattern showing that reductions in tariffs and exchange rate appreciations increase the pace of job reallocation within sectors. We also find, however, some evidence of declining net employment growth as trade exposure increases. For example, we find some evidence that in the wake of tariff reductions, there is lower net employment growth.     

Testing for fiscal sustainability: New evidence from the G-7 and some European countries

Whether or not a government deficit is sustainable has important implications for policy. If the debt of a nation is sustainable, then it implies that the government should have no incentive to default on its internal debt. In this article we examine whether or not the debt-GDP ratios of the G-7 and some European countries can be characterized by a unit root process with the non-linear trend and asymmetric adjustment. The econometric methodology allows us to determine whether the stationarity holds for the government's debt–GDP ratio after considering the non-linear trend. Among the main results, it is found that it is very likely that the debt–GDP ratios of Canada, Germany, the US and Italy are stationarity after taking account of the non-linear trend in the long run. Nevertheless, it is model-dependent for the debt–GDP ratios of these countries to be asymmetrically adjusted after taking the non-linear trend into consideration.     

The equilibrium relationship among money,income, prices,and interest rates: evidence from a threshold cointegration test

The long-run equilibrium relationship among money, income, prices, and interest rates in Japan is investigated by the threshold cointegration test, which allows for asymmetric adjustment, introduced by Enders and Siklos (2001 Enders, W and Siklos, PL. 2001. Cointegration and threshold adjustment. Journal of Business and Economic Statistics, 19: 166–76. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). The threshold cointegration approach provides clear evidence of the cointegration relationship characterized by asymmetric adjustment. By allowing for asymmetric adjustment, results are obtained showing the stability of the money demand function, similar to Lucas (1988 Lucas, RW Jr. 1988. Money demand in the United States: a quantitative review. Carnegie-Rochester Conference Series on Public Policy, 29: 137–68.  [Google Scholar]), who pointed out that the money demand function is stable if unit income elasticity is imposed. In particular, the estimated results show that the adjustment process toward equilibrium is highly persistent above an appropriately estimated threshold, whereas the adjustment process toward equilibrium quickly converges below it. This finding indicates that deviations from equilibrium resulting from increases in money or decreases in income and prices are highly persistent.     

Government spending and revenues in the Greek economy: evidence from nonlinear cointegration

This paper attempts to re-evaluate the long-run macroeconomic relationship between government revenues and expenditures of the Greek economy over the period 1999–2010. The empirical analysis applies the newly developed asymmetric ARDL cointegration methodology of Shin et al. (2011) which permits more flexibility in the dynamic adjustment process towards equilibrium, than in the classical case of a linear model. Our findings point towards the fiscal synchronization hypothesis, supporting evidence of asymmetric interactions between the two fiscal components in both the long- and the short-run time horizon. More particularly, in the long-run, the negative changes of expenditures dominate the response of revenues, while the opposite applies in the response of expenditures.
