Persistent real exchange rates

Over the past decades, product market deregulation has typically preceded labor market reforms in OECD countries. This paper incorporates labor market rigidities in a model of footloose capital in order to study how globalization might affect the trade-offs generated by labor market regulation and put pressure on labor market institutions. In this two-sector model, globalization ultimately reduces labor market rigidities through either one of two channels: capital mobility triggers a re-allocation of resources, which trade integration amplifies, away from the high-rent / highly-unionized sector; the threat of costly relocations encourages labor market deregulation. The latter channel is more efficient because it avoids sub-optimal sectoral specialization.     

Into the Mussa puzzle: monetary policy regimes and the real exchange rate in a small open economy

Industrial countries moving from fixed to floating exchange rate regimes experience dramatic rises in the variability of the real exchange rate. This evidence, forcefully documented by Mussa [Nominal exchange regimes and the behavior of real exchange rates: evidence and implications. Carnegie-Rochester Conference Series on Public Policy 25 (1986) 117], is a puzzle because it is hard to reconcile with the assumption of flexible prices. This paper lays out a dynamic general equilibrium model of a small open economy that combines nominal price rigidity with a systematic behavior of monetary policy able to approximate a continuum of exchange rate regimes. A version of the model with complete exchange rate pass-through is broadly consistent with Mussa’s findings. Most importantly, this holds independently of the underlying source of fluctuations in the economy, stressing the role of the nominal exchange rate regime per se in affecting the variability of the real exchange rate. However, only a model featuring incomplete exchange rate pass-through can account for a broader range of exchange rate statistics. Finally there exist ranges of values for either the degree of openness or the elasticity of substitution between domestic and foreign goods for which the baseline model is also consistent with the empirical insensitivity of output volatility to the type of exchange rate regime, as documented by Baxter and Stockman [Journal of Monetary Economics 23 (1989) 377].     

Sectoral adjustment costs and real exchange rate dynamics in a two-sector dependent economy

This paper develops a two-sector model in which intersectoral capital movements involve adjustment costs, expressed as capital lost in the transformation process. These costs have important consequences for the dynamics of capital accumulation and particularly for real exchange rate dynamics. Persistent deviations of the real exchange rate from its equilibrium are derived and for plausible values of the adjustment cost parameters are consistent with the observed degree of real exchange rate persistence. For low adjustment costs the dynamics are qualitatively similar to those of the standard Heckscher-Ohlin technology. For high adjustment costs, the model converges to the specific-factors model. Thus our framework includes these two standard models as polar extremes.     

Lending booms, sharp reversals and real exchange rate dynamics

Emerging markets in the 1990s experienced periods of booms followed by collapses in gross domestic product, consumption, traded and non-traded sector output and real exchange rate movements alongside unprecedented movements in foreign investor participation in these economies. An important feature of these episodes is the asymmetry in the pattern of booms and collapses. We introduce a natural search friction into the foreign investment decision in a small open economy and demonstrate that this can generate the asymmetry observed in the data. The magnitude of the reversals predicted by the model can be quantitatively large and empirically relevant.     

Why is it so difficult to beat the random walk forecast of exchange rates?

Recent empirical evidence suggests that the time series behavior of the real exchange rate is well approximated by a nonlinear, exponential smooth transition autoregressive (ESTAR) model. This nonlinearity helps resolve a number of puzzles concerning the persistence and volatility of real exchange rates. In this paper, we explore whether it may also help resolve the well-known difficulties of exchange rate forecasting. We develop a bootstrap test of the random walk hypothesis of the nominal exchange rate, given ESTAR real exchange rate dynamics. We find strong evidence of predictability at horizons of 2 to 3 years, but not at shorter horizons.     

Job creation, job destruction, and the real exchange rate

Welfare gains from trade are reduced by adjustment costs associated with factor reallocation, but most studies of the effects of trade on labor markets focus only on net employment change. This paper takes a step toward identifying trade-related adjustment costs by estimating the effects of real exchange rates on labor reallocation using a new model of gross job creation and destruction applied to detailed U.S. manufacturing industries between 1973 and 1993. Trend real exchange rates significantly affect job reallocation but not net employment. Cyclical real exchange rates significantly affect net employment through job destruction only.     

Fixed exchange rates and trade

A classic argument for a fixed exchange rate is its promotion of trade. Empirical support for this, however, is mixed. While one branch of research consistently shows a small negative effect of exchange rate volatility on trade, another, more recent, branch presents evidence of a large positive impact of currency unions on trade. This paper helps resolve this disconnect. Our results, which use a new data-based classification of fixed exchange rate regimes, show a large, significant effect of a fixed exchange rate on bilateral trade between a base country and a country that pegs to it. These results suggest an economically relevant role for exchange rate regimes in trade determination since a significant amount of world trade is conducted between countries with fixed exchange rates.     

Real exchange rate targeting and macroeconomic instability

Using an optimizing model of a small open economy, this paper studies the macroeconomic effects of PPP rules whereby the government increases the devaluation rate when the real exchange rate—defined as the price of tradables in terms of nontradables—is below its long-run level and reduces the devaluation rate when the real exchange rate is above its long-run level. The paper shows that the mere existence of such a rule can generate aggregate instability due to self-fulfilling expectations. The result is shown to obtain in both flexible- and sluggish-price environments.     

Long-run real exchange rates in the Four Little Dragons

This paper analyses changes in the exchange rate arrangements and policy and their impact on the long-run real exchange rates of the Asian Four Little Dragons. It is found that purchasing power parity is a basic guide in formulating the exchange rate policy of the Four Little Dragons and that exchange rate regimes are very responsive to the effect of major external disturbances on prices. Thus, the exchange rate policy and arrangements are important factors in shaping the behaviour of the real exchange rates of the FLDs, which tend to return to the long-run average value. To test the null hypothesis that purchasing power parity does not hold between the Four Little Dragons and the United States, two cointegration tests, the augmented Dickey-Fuller (ADF) test and the Johansen test, are applied. As the symmetry and proportionality conditions are not supported by the data, the tests are conducted in a trivariate system. While the ADF test does not support PPP, evidence of cointegration is found by the Johansen test.     

Exchange rates and prices: Evidence from China

This article develops a pricing model that incorporates an industrial organization approach with the traditional quantity theory of money to explain the impact of exchange rates on consumer prices. Using time-series data on prices and exchange rates of China, the model replicates the main features of the observed facts: exchange rates influence consumer prices through changing import prices; money supply and output influence consumer prices following the quantity theory. The estimating results show that exchange-rate pass-through to consumer prices is low and increases from the short run to the long run. The extent of pass-through is likely to depend on markup adjustment and marginal costs.     

Determinants of the real effective exchange rate in the Russian Federation

This article examines the main determinants of the Russian real effective exchange rate (REX) movements over the transition period started in the early 1990s. To understand the forces that drive exchange rate dynamics, five strands of the empirical literature have been combined ina time series dimension. The results suggest a positive long-run cointegration relationship between the REX, oil price, productivity and government financial position and a negative relation with international reserves. Managing international reserves and fiscal policies have therefore, the effect of mitigating the impact of oil/terms of trade and productivity shocks on the REX.

Impact of commodity prices on exchange rates in commodity-exporting countries

This paper studies the link between real exchange rates and commodity prices, over the period 1993M1–2018M12, for commodity-exporting countries by analysing countries individually and considering the possibility of structural breaks. Our results suggest that: (a) the movements in the price of the main commodity (i.e., the one whose share is at least 20% of total commodity export) affect significantly to the real exchange rate; (b) the sign of the effect of commodity prices on real exchange rate is not clearly positive (as was found by earlier analyses using panel data), but it depends on the country considered; and (c) the negative effects of the possession of natural resources observed in the past decades seem not to be now overwhelming.

Industrial research and development and real exchange rate depreciation in a small open economy

To examine how changes in relative national prices affect innovation input, this paper studies the impact of changes in industry-specific effective real exchange rates on industrial R&D expenditures in Korea. In particular, it explores the heterogeneous responses of industries with different export intensities. Employing dynamic panel data estimation techniques, the results suggest that among industries with medium levels of export intensity a lagged depreciation in industry-specific effective real exchange rate leads to a decline in contemporaneous industry-level R&D expenditures. However, this adverse effect is insignificant for industries that either mostly serve the domestic markets or that are heavily engaged in foreign markets.     

The impact of world oil price shocks on the Canada/U.S. real exchange rate

This article investigates whether and how changes in the world oil price affect the Canada/U.S. real exchange rate. We applied vector autoregression and vector error correction models for the real exchange rate, world oil price, monetary differential, government spending, and productivity differential between the two countries. Our results demonstrate that a surge in the world oil price will lead to an appreciation of the Canadian dollar in the short and long term. Product differentials and U.S. government spending have a negative impact on the Canada/U.S. real exchange rate, and Canadian government spending leads to a depreciation of the Canadian dollar.     

Identifying macro-determinants of remittance flows to a developing country: The case of Uganda

This paper employs minimum Lagrange Multiplier (LM) unit root tests for endogenous structural breaks combined with ARCH and GARCH models to investigate how key macrovariables impact diaspora remittances. Since remittances can reverse-cause exchange rate movements and domestic income, we use changes in the world price of oil denominated in U.S. dollars to proxy movements in the Uganda shilling nominal effective exchange rate. To control for endogenous bias between remittances and income, we use rainfall shocks as proxies for income shocks in a non-oil-producing developing economy dominated by agricultural sector and its related activities. In addition, large movements in oil price and rainfall shocks typically cause large supply shocks that can significantly impact size of remittance inflows. We control for interest rate differential, political business cycles and seasonality. Results indicate that accounting for structural change in intercepts (levels) and slopes (trends) of key macroeconomic determinants of remittances around their major structural break points significantly increases their explanatory power. In particular, positive (negative) innovations in income and depreciation (appreciation) in the currency of a recipient developing country are negatively (positively) correlated with remittance inflows. These results are robust across different model specifications.     

Forecasting exchange rates with commodity prices—a global country analysis

This paper investigates the predictive properties of import and export prices of commodities on the exchange rates. A period from 1993 to 2016 is considered. We find that forecasts of the exchange rate adding commodity export and import prices are superior to those neglecting these variables. This holds irrespective of whether the countries are net exporters or importers of commodities. However, the forecasting power was even better in the 1990s and seems to have decreased since that that time. Nevertheless, forecasts can even today be improved considerably by adding commodity prices.

Impact of exchange rates on ASEAN's trade in the era of global value chains: An empirical assessment

ABSTRACT

Exchange rate risk remains a key concern for export-oriented economies in Southeast Asia. Traditionally, export performance is thought to be adversely affected by exchange rate appreciation and high exchange rate volatility. Nonetheless, in the context of global value chains where export production relies heavily on imported inputs, the trade effects of exchange rate may be weakened. Using the OECD-WTO Trade in Value-added (TiVA) database, this paper seeks to tease out the association between exchange rate movements, volatility and aggregate exports of goods and services among ASEAN economies. More importantly, it investigates whether integration into GVCs affects these relationships. Applying panel regression techniques to a sample of eight ASEAN countries over the period 1995–2011, we found that high share of foreign value added (FVA) embodied in exports almost completely offsets the negative effect of an appreciation in the real effective exchange rate (REER) on real gross exports. At the same time, high FVA share also dampens the negative association between exports and increased REER volatility.
