The impact of foreign interest rates on the economy: The role of the exchange rate regime

It is often argued that many economies are affected by conditions in foreign countries. This paper explores the connection between interest rates in major industrial countries and annual real output growth in other countries. The results show that high foreign interest rates have a contractionary effect on annual real GDP growth in the domestic economy, but that this effect is centered on countries with fixed exchange rates. The paper then examines the potential channels through which major-country interest rates affect other economies. The effect of foreign interest rates on domestic interest rates is the most likely channel when compared with other possibilities, such as a trade effect.     

The exchange regime and trade balance in Turkey

Over the last 15 years, high trade deficits have become a source of external vulnerability for the relatively stabilized Turkish economy. This corresponds to the period where authorities have been following a floating exchange rate regime. Thus, this study aims to empirically show whether the adopted exchange rate regime has an impact on the trade balance for the period of 1987 Q1 to 2015 Q2. Estimation results indicate that there is a long-run relationship between the real effective exchange rate and trade balance under both fixed and floating regimes in Turkey, but there is no evidence for the J-curve hypothesis.     

Does the exchange rate regime matter for real shocks? Evidence from windstorms and earthquakes

Does the choice of exchange rate regime affect an economy's adjustment to real shocks? Exploiting the unpredictability and economic exogeniety of windstorms-hurricanes and typhoons-and earthquakes this paper assesses the often contrasting answers found in the theoretical literature. There is robust evidence that exchange rate flexibility helps an economy better adjust to real shocks. And consistent with the channels emphasized in the classic literature on exchange rates and shocks, differences in the behavior of the export sector help explain the different reactions between the two regimes.     

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].     

Terms of trade and exchange rate regimes in developing countries

Since Friedman [Essays in Positive Economics, University of Chicago Press, Chicago (1953) 157-203] an advantage often attributed to flexible exchange rate regimes over fixed regimes is their ability to insulate more effectively the economy against real shocks. I use a post-Bretton Woods sample (1973-96) of 75 developing countries to assess whether the responses of real GDP, real exchange rates, and prices to terms-of-trade shocks differ systematically across exchange rate regimes. I find that responses are significantly different across regimes in a way that supports Friedman’s hypothesis. The paper also examines the importance of terms-of-trade shocks in explaining the overall variance of output and prices in developing countries.     

The impact of parallel market exchange rate volatility and oil exports on real GDP in Syria: Evidence from the ARDL approach

This paper investigates the impact of parallel market exchange rate volatility and trade on real GDP and real GDP growth in the Syrian economy over the period of 1990Q1–2010Q4. To this end, we first construct a parallel market exchange rate volatility indicator. Second, we estimate an autoregressive distributed lag (ARDL) model where we include our indicator of volatility among the main determinants of real GDP. Our findings imply that real GDP can be explained by three main variables: parallel market exchange rate, money supply, and oil exports. The long-run equilibrium reveals that parallel market exchange rate volatility has a negative impact on real GDP compared to the positive impact of money supply and oil exports. In contrast, the short-run impact of parallel market exchange rate volatility on real GDP growth is positive and very small counter to the long-run impact. Furthermore, the coefficient of the error correction term of the estimated ARDL model indicates that real GDP deviation from the equilibrium level will be corrected by about 10% after each quarter.     

Consumption and exchange rate uncertainty: Evidence from selected Asian countries

We set out to assess the effects of exchange rate uncertainty on real consumption in selected Asian countries. Consumption influences business cycles, which in turn shape short-run monetary policy decisions. Hence, understanding factors driving consumption is appealing to policymakers. To date, few studies have analysed the effects of uncertainty on consumption. The available ones generally focus on the long-run effects, in spite of the fact that the short-run persistence and adjustments to equilibrium are equally relevant. Our study takes these limitations seriously by distinguishing the short- and long-run effects of exchange rate uncertainty on consumption. Using a flexible dynamic panel data technique that allows long-run effects to be homogeneous and the short-run effects to be heterogeneous, we find that uncertainty impedes consumption in the long run. In the short run, however, the effects are immaterial. This evidence remains robust to the measure of uncertainty, asymmetric uncertainty, inflation and the global financial crisis of 2008. By decomposing uncertainty into its temporary and permanent components, we find that the latter have a stronger effect on consumption in the long run than the former. Although both components demand policy attention, the evidence suggests that policymakers should be more concerned with permanent uncertainty.     

Exchange rate regime and external adjustment: An empirical investigation for the US

This paper analyses the relationship between the US net external position and the exchange rate regime. I find a structural break in the US net external position at the end of the Bretton Woods system of fixed exchange rates that changed both the mean and variance of the series. On average, the US changed from a creditor to a debtor position and the variance of the external position increased during the floating period. This increase is to a large extent due to the valuation component of external adjustment that accounts for 54% of the variance of the US external position during the floating period but only 29% during the fixed exchange rate period. Further analysis shows that the exchange rate regime mainly affects the valuation channel of external adjustment. There is also evidence of another structural break in the US external position around the time of the introduction of the euro. Finally, I document asset pricing implications from the relationship between the exchange rate regime and the external adjustment process, as external imbalances predict the foreign exchange once the exchange rate regime is taken into account.

Should the exchange rate be a shock absorber?

This paper examines the welfare case for the exchange rate as a “shock absorber”, cushioning an economy in face of shocks to world demand for its good. We provide an example in which, although the exchange rate acts perfectly as a shock absorber, stabilizing output around the natural rate, and eliminating the impact of nominal rigidities, it may in fact be better to prevent the exchange rate from adjusting at all. The explanation for this is that, with incomplete international financial markets, the natural rate is inefficient; it does not respond enough to demand shocks. While fixing the exchange rate increases the volatility of consumption, the pro-cyclical nature of monetary policy under a fixed exchange rate allows for a more efficient composition of consumption between home and foreign goods. Furthermore, for the shocks examined, a welfare maximizing monetary rule always dampens exchange rate volatility relative to that of a free float, and in some cases may imply a fixed exchange rate.     

Chaos and the exchange rate

Chaotic exchange rate models are structural models built in discrete time (difference equations), and show that with orthodox assumptions (PPP, interest parity, etc) and introducing plausible nonlinearities in the dynamic equations, it is possible to obtain a model capable of giving rise to chaotic motion. However, none of these models is estimated, and the conclusions are based on simulations: the empirical validity of these models is not tested. In this paper, a continuous time (the exchange rate is obviously a continuous variable) exchange rate model is built as a non-linear set of three differential equations and its theoretical properties (steady state, stability, etc,) analysed. The model is then econometrically estimated in continuous time with Italian data and examined for the possible presence of chaotic motion. This paper also shows that the continuous time estimation of economic models built as systems of nonlinear differential equations is a very powerful tool in the hands of the profession.     

Financial integration and the wealth effect of exchange rate fluctuations

Recent years have witnessed a large increase in international financial integration in the form of largely offsetting cross-holdings across countries. We assess how such financial leverage affects the international transmission of monetary shocks, and find that it leads to sizable welfare differentials that far exceed the impact due to nominal rigidities. We document the relevance of the exact nature of holdings, with bond holdings associated with larger effects than equity holdings. The impact of financial leverage on welfare is also sensitive to the extent of exchange rate pass-through and the substitutability between goods produced in different countries.     

Balance sheet effects and the choice of exchange rate regime in developing countries

We investigate the choice of regime amongst hard pegs, soft pegs, managed floats and independent floats for a panel of developing countries. There is evidence of a matched ordering of regimes and country characteristics. We find some evidence for the ‘balance sheet' hypothesis that foreign liabilities in the banking system and foreign debt are associated with less exchange rate flexibility, particularly when a ‘de facto’ regime classification is used. Easily the best predictor of a country's current regime is its regime in the previous year.     

Monetary policy, foreign exchange intervention, and the exchange rate in a unifying framework

The structural VAR model is developed to jointly analyze the effects of foreign exchange intervention and (money or interest rate setting) conventional monetary policy on the exchange rate, the two types of policy reactions to the exchange rate, and interactions between the two types of policies. First, many interactions among the two types of policies and the exchange rate are found, which suggests that a joint analysis is important. Second, foreign exchange intervention has substantial effects on the exchange rate, reacts to the exchange rate significantly (to stabilize the exchange rate), and signals future conventional monetary policy stance changes (to back up the intervention). This suggests the importance of modeling foreign exchange intervention explicitly in the study of monetary policy and exchange rate behaviors. Many other interesting results on the interactions among the two types of policies and the exchange rate are also documented.     

The choice of exchange rate bands: balancing credibility and flexibility

This paper develops a framework for the optimal choice of exchange rate bands within an environment in which policymakers dislike nominal exchange rate variability, but value the flexibility to adjust the nominal exchange rate in response to shocks, in order to attain real exchange rate objectives. The paper provides an endogenous characterization of the optimal exchange rate band in terms of the underlying distribution of shocks to the current and capital accounts of the balance of payments and in terms of the commitment reputation of policymakers.     

Do inpayments and outpayments respond to exchange rate changes asymmetrically: Evidence from Malaysia

Since the pass-through of exchange rate changes on import and export prices are asymmetric, we expect a country’s inpayments (export earnings) and outpayments (cost of imports) to also react to exchange rate changes asymmetrically. We demonstrate this hypothesis by considering trade between Malaysia and each of her 11 largest trading partners. We find that while the short-run effects of exchange rate changes on Malaysia’s inpayments and outpayments are asymmetric with all partners, the long-run asymmetric effects are present in less than half of the partners. The results are partner specific.     

The asymmetric effects of exchange rate fluctuations on output and prices: Evidence from developing countries

This paper examines the asymmetric effects of exchange rate fluctuations on real output and price in developing countries. The theoretical model decomposes movements in the exchange rate into anticipated and unanticipated components. Unanticipated currency fluctuations determine aggregate demand through exports, imports and the demand for domestic currency, and determine aggregate supply through the cost of imported intermediate goods. The evidence indicates that the supply channel leads to output contraction and price inflation in the face of unanticipated currency depreciation. In contrast, the reduction in net exports determines output contraction without reducing price inflation in the face of unanticipated currency appreciation.     

Can the new open economy macroeconomic model explain exchange rate fluctuations?

This paper explores the successes and failures of the new open economy macroeconomics more critically by addressing the performance of the model at all frequencies along the line of Watson's [Watson, M.W., 1993. Measures of Fit for Calibrated Models, Journal of Political Economy 101, 1011-1041] measures of fit. This paper shows that the NOEM model with either PCP or PTM is not successful in generating the spectral density of the selected variables calculated from the data. In particular, the model cannot generate mass spectra of the exchange rates at low frequencies as in the data. It shows that the NOEM model with either separable preference or incomplete asset market cannot generate the typical hump-shaped spectra of exchange rates.     

Explaining the exchange rate pass-through in different prices

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).     

The endogeneity of the exchange rate as a determinant of FDI: A model of entry and multinational firms

This paper argues that when the exchange rate and projected sales in the host country are jointly determined by underlying macroeconomic variables, regressions of FDI flows on both exchange rate levels and volatility are subject to bias. The results demonstrate that a multinational firm's response to exchange rate volatility will differ depending on whether the volatility arises from shocks in the firm's native or host country. It is the first study to depart from the representative-firm framework in an analysis of direct investment behavior with money.
