Misalignments of real exchange rates and the credibility of nominal currency bands

Misalignments of Real Exchange Rates and the Credibility of Nominal Currency Bands. — This paper analyzes a sticky-price target zone model in which realignment risk is modeled endogenously as a function of the degree of real exchange rate misalignments. The implications of the model are used to investigate the credibility of selected nominal ERM exchange rate bands. We find that a lack of credibility of the ERM currency bands occurs mostly in countries with substantial swings and persistent misalignments of real exchange rates. These findings suggest that the major real appreciations in some European bilateral real exchange rates between 1987 and 1992 have been pivotal in triggering the ERM currency crises of 1992 and 1993.     

Learning about fundamentals: The widening of the French ERM bands in 1993

Learning about Fundamentals: The Widening of the French ERM Bands in 1993. — The authors incorporate a Bayesian learning model into a fairly general model of exchange rate determination in discrete time. The model is applied to the period following the widening of the French-German ERM bands in August 1993, in which a systematic underprediction of the franc can be observed until February 1994. A (substantial) part of these forecast errors can be mimicked by a Bayesian learning process. Simulations with our model show that, after the widening of the bands, agents, contrary to their initial expectations, gradually learned that the true process driving monetary conditions in France had not changed notably.     

Excess returns in the EMS: Do “weak” currencies still exist after the widening of the fluctuation bands?

Excess Returns in the EMS: Do “Weak” Currencies Still Exist after the Widening of the Fluctuation Bands? — The authors analyze the issue of how the different institutional arrangements within the ERM have affected the behaviour of excess returns on DM-denominated assets and contribute to the debate on the future of the EMS. Their approach consists in estimating simple forecasting models for interest differentials, and testing for the presence of significant (negative) mean prediction errors. The comparison between predicted and actual outcome indicates that the new system might be characterized by the virtual disappearance of “weak” currencies, as the widening of the bands has removed the expectations of realignments which resulted in high interest differentials.     

The importance of technology-based intersectoral linkages for market share dynamics

The Importance of Technology-Based Intersectoral Linkages for Market Share Dynamics. — The paper introduces technology-based intersectoral linkages (or technological spillovers) in an empirical model of international market share dynamics. The Pavitt taxonomy is applied as a yardstick for interpreting the empirical results. Overall, the results appear to be broadly consistent with the criteria behind the taxonomy, on the relative importance of the different factors of competitiveness in the different sectors. In particular, unit labour costs appear to play the largest role in supplier-dominated industries, ‘own sector’ technological activity plays the largest role in science-based industries, upstream linkages in scale-intensive and downstream linkages in specialized-supplier types of industries.     

Real exchange rates and unit root tests

Real Exchange Rates and Unit Root Tests. — This paper examines monthly OECD exchange rate data (1979–1997) using univariate and panel data unit root tests. Some of these tests support the hypothesis of a unit root. But tests of cointegration reveal the existence of weak purchasing power parity relationships between bilateral nominal exchange rates and relative prices. We suggest that researchers need not conduct unit root tests on real exchange rate data when a modified version of PPP is used; or if there is a long enough time series. Given the definition of real exchange rates, the indicator should be stationary and should have intrinsic mean reverting behaviour.

What’s trade got to do with it? Relative demand for skills within Swedish manufacturing

What’s Trade Got to Do with It? Relative Demand for Skills within Swedish Manufacturing. — This paper seeks to identify the contribution of trade and technological change to the increase in inequality between skilled and unskilled workers in Sweden since the 1970s. An empirical approach is adopted which allows for the outsourcing of the low-skill parts of the production chain to low-wage locations and is applied to detailed industry and bilateral trade data, the latter distinguishing between low-wage sources of imports and OECD countries. The paper finds that, in contrast to previous studies, trade with low-wage countries may have contributed to the rise in inequality in Swedish manufacturing. The empirical results also suggest that the increased use of technology also played a role in creating greater inequality between skilled and unskilled workers in Sweden, with the magnitude of this impact increasing in the 1990s.     

Export behavior and productivity growth: Evidence from Italian manufacturing firms

Export Behavior and Productivity Growth: Evidence from Italian Manufacturing Firms. — This paper provides econometric evidence supporting the hypothesis that exporting implies learning effects. Learning-by-exporting is modeled as a change, induced by export behavior, in the stochastic process governing firms’ productivity. Empirically, this is implemented by specifying cross-section regressions of labor productivity growth on measures of export behavior, controlling for past productivity growth and other firms’ characteristics. Using a sample of Italian manufacturing firms, it is found that exporters do not exhibit faster productivity growth. Nevertheless, growth in value added per worker has a positive and significant relation with firms’ export intensity. In other words, only firms substantially involved in exporting have a significantly higher rate of productivity growth. This result suggests that learning-by-exporting is by no means simply the outcome of the presence in the export market.     

The determinants of export performance: A firm-level study of Italian manufacturing

The Determinants of Export Performance: A Firm-Level Study of Italian Manufacturing. — This paper analyzes some determinants of a firm’s probability of exporting and export intensity and presents the findings of an empirical study carried out on a large sample of Italian firms. On the basis of Probit and Tobit estimates, it emerges that these determinants change according to the size of firms. In particular, only for small firms is the relationship between size and export performance positive. The export activity of small and medium-sized firms decreases with the share of sales due to subcontracting. Larger firms, instead, benefit more from being affiliated with business groups and performing innovative activities of a different nature.     

What Should the Weights of the Three Major Currencies be in a Common Currency Basket in East Asia?*

We consider what type of regional common currency should be introduced in East Asia in the future. The common currency basket is, in itself, more desirable as an anchor currency. In this paper we define two types of currency basket and investigate the long‐term sustainability of adopting a common currency basket in East Asia. From our empirical results, a larger weight (but less than 100 percent) for the US dollar in the common currency basket tends to make bilateral exchange rates among East Asian countries stable in the long run.     

REER Imbalances and Macroeconomic Adjustments in the Proposed West African Monetary Union

With the spectre of the euro crisis hunting embryonic monetary unions, we use a dynamic model of a small open economy to analyse real effective exchange rate (REER) imbalances and examine whether the movements in the aggregate real exchange rates are consistent with the underlying macroeconomic fundamentals in the proposed West African Monetary Union (WAMU). Using both country‐oriented and WAMU panel‐based specifications, we show that the long‐run behaviour of the REERs can be explained by fluctuations in the terms of trade, productivity, investment, debt and openness. While there is still significant evidence of cross‐country differences in the relationship between underlying macroeconomic fundamentals and corresponding REERs, the embryonic WAMU has a stable error correction mechanism, with four of the five cointegration relations having signs that are consistent with the predictions from economic theory. Policy implications are discussed, and the conclusions of the analysis are a valuable contribution to the scholarly and policy debate over whether the creation of a sustainable monetary union should precede convergence in macroeconomic fundamentals that determine REER adjustments.     

Exchange rate uncertainty and the efficiency of the forward market for foreign exchange

Exchange Rate Uncertainty and the Efficiency of the Forward Market for Foreign Exchange. — The paper investigates to what extent exchange rate uncertainty can account for the observed deviations from the forward market efficiency hypothesis (FMEH). The empirical analysis employs a simple varying parameter regression to allow uncertainty to modify the central parameters of the FMEH in a direct way. Uncertainty is proxied by significant exchange rate changes. The results indicate that there is considerable support for the FMEH if one allows the intercept term to vary over time.     

A fractional cointegration approach to empirical tests of PPP: New evidence and methodological implications from an application to the Taiwan/US dollar relationship

A Fractional Cointegration Approach to Empirical Tests of PPP: New Evidence and Methodological Implications from an Application to the Taiwan/ US Dollar Relationship. —This paper applies a relatively new concept of fractional cointegration to shed some light on the validity of purchasing power parity as a long-run equilibrium condition, using the Taiwan/US dollar exchange rate. Findings suggest that, while standard tests of cointegration fail to support cointegration between nominal exchange rates, domestic and foreign prices, the fractional cointegration analysis permits deviations from equilibrium to follow a fractionally integrated process and hence captures a much wider class of parity or mean-reversion behaviour. The paper concludes by indicating areas in which fractional cointegration will be a particularly appropriate technique to unearth previously unfounded temporal characteristics.     

Factor shares,inequality, and capital flows

I present an endogenous growth model where innovations are factor saving and model the choice of technologies in an Overlapping Generations framework. Markets are competitive and factor prices are determined by marginal productivity of factors; therefore, the income share of reproducible factors increases with the stage of development. Beyond the standard results of this type of model I find that (i) without bequests long‐run growth is not possible, (ii) if the economy presents long‐run growth then intrageneration inequality may last forever but if the economy does not present long‐run growth then in steady state, there is no intrageneration inequality, (iii) when the economy is open, the pattern of capital flows depends not only on the relative abundance of factors but also on the technologies and, for this reason, capital may not flow from rich to poor economies, and (iv) consistently, capital flows may not help to break poverty traps.     

Managing in the Middle: Characterizing Singapore's Exchange Rate Policy*

It is by now common knowledge that there can be a significant divergence in the de facto versus de jure exchange rate regimes operated by economies. Although much of the recent published literature in Asia has focused on the crisis-hit economies, Korea and Thailand in particular, scant attention has been paid to Singapore, which officially targets its nominal effective exchange rate (around a band). The present paper examines the degree of exchange rate intervention for Singapore using various methods of assessing de facto exchange rate regimes. In the main, we show that although the Singapore dollar is primarily influenced by the US dollar, in keeping with its de jure classification of a basket pegged regime, other major currencies, such as the yen and the euro, also impact the Singapore dollar. There is also evidence to indicate that Singapore uses the nominal effective exchange rate strategically as a policy instrument to satisfy domestic inflation objectives.     

Strong sterling pound and weak European currencies in the crises: Evidence from covered interest parity of secured rates

In the post Lehman period, the interest rate of the US dollar became low on the forward contract because of“flight to quality” to the international currency. However, in the Euro crisis, that of the Sterling pound became equally low, while the other European currencies such as the Danish kroner increased its their interest rate. By using secured rates, the following analysis examines why the Sterling pound and the Danish kroner showed asymmetric features in deviations from the covered interest parity (CIP) condition. The regression results suggest that there was a structural break in the determinants of the deviations across the European currencies in the two crises. Currency-specific money market risk was critical in explaining the deviations in the global financial crisis (GFC), while EU bank credit risk and global market risk were useful in explaining the deviations in the Euro crisis. In particular, EU bank credit risk and global market risk had asymmetric effect on the deviations. The asymmetry explains contrasted features between the Sterling pound and the Danish kroner.     

Deviations from long-run equilibria and probabilities of devaluations: An empirical analysis of Danish realignments

Deviations from Long-Run Equilibria and Probabilities of Devaluations — An Empirical Analysis of Danish Realignments. — The probabilities of realignments between the Danish krone and the D-mark are investigated for the 1979–1995 period. Two multivariate systems are estimated. In the I (1) systems, the deviations from the cointegration relations are used as explanatory variables when determining the probabilities of exchange rate changes. It is found that real imbalances in the economy have to a large extent determined the probabilities of central parity changes. Furthermore, the probabilities of central parity changes have been significantly lower after 1983.     

Divergence indicators and the volatility smoothness in semi-fixed exchange rate regimes

Divergence Indicators and the Volatility Smoothness in Semi-Fixed Exchange Rate Regimes. —Fixed or semi-fixed exchange rate regimes have volatility paths that are in general less smooth than their free floating counterpart. Moreover, there tends to be a correlation between the lack of smoothness and the weakness of the currency. In this article, the effects of divergence from central parity on the smoothness of the volatility are discussed within the framework of a TGARCH model. It is shown that, for various EMS rates, the divergence indicator has a statistically significant effect on the smoothness of the volatility path.     

Asian Currency Unit (ACU), deviation indicators and exchange rate coordination in East Asia: A panel-based convergence approach

Employing the panel convergence method of Phillips and Sul (2007) to the nominal deviation indicators of two recent unofficial constructions of an Asian Currency Unit (ACU) index, this paper examines the existence and extent of convergence in the movements of East Asian currencies against the ACU. Empirical results reveal that intra-East Asian exchange rate movements have not converged to form one, cohesive and unified bloc where currencies share homogenous movements, regardless of whether one examines the data on intra-East Asian exchange rate movements before or after the collapse of Lehman Brothers in September 2008. Instead, a separate number of convergent clubs or blocs in the region have formed in recent years. Finally, and most importantly, we observe at the end of the period of our examination that economies in the region are, generally, converging at different speeds to two opposing poles of convergence, that is, groups of relatively depreciating currencies and, on the other, groups of relatively appreciating currencies.
