China’s rise,asymmetric trade shocks and exchange rate regimes

China’s rapid growth provides a natural experiment to study the effects of asymmetric trade shocks on the competitiveness of OECD countries. The different levels of exposure to Chinese trade competition, as measured using an index of export similarity, triggered asymmetric shocks as China’s trade surged. Motivated by a Ricardian framework, this paper finds that countries with exports similar to those of China experience a loss in competitiveness compared with countries with a different trade structure. Once an additional layer of distinction is introduced between fixed and flexible exchange rate regimes, I find that countries with a fixed exchange rate and with relatively high similarity to China experience a real appreciation.     

Output stabilization in fixed and floating regimes: Does trade of new products matter?

This paper studies the dynamics of output and export margins in the aftermath of global shocks in fixed and floating exchange rate regimes. Using a panel vector autoregressive model with exogenous factors, it traces the mean responses of output, terms of trade, extensive and intensive margins to real and nominal shocks in 22 developed economies over the period 1988–2011. We find remarkable differences in the transmission of shocks across exchange rate regimes. Adjustment takes place mainly at the extensive margin in fixed regimes, and implies a crowding out of intensive margins that is not present among floaters. Large movements at the extensive margin are associated with a weaker performance in terms of output stabilization. Our findings are robust to alternative sample selections and identification of the shocks. The evidence in the paper stresses a novel advantage of flexible exchange rates based on their ability to smooth the fluctuations in trade of new products.     

Exchange rate volatility and regime change: A Visegrad comparison

We analyze exchange rate volatility in the Visegrad Four countries during the period in which they abandoned tight regimes for more flexible ones. We account for path dependency, asymmetric shocks, and movements in interest rates. In addition, we allow for a generalized error distribution. The overall findings are that path-dependent volatility has a limited effect on exchange rate developments and that the introduction of floating regimes tends to increase exchange rate volatility. During the period of flexible regimes, volatility was mainly driven by surprises. Asymmetric effects of news tend to decrease volatility under the floating regime. Interest differentials impact exchange rate volatility contemporaneously under either regime, although we find no intertemporal effect of interest differentials.

Terms‐of‐Trade Shocks and Exchange Rate Regimes in a Small Open Economy*

We examine the impact of terms‐of‐trade shocks on key macroeconomic variables by numerically solving a dynamic stochastic general equilibrium model of a small open economy. The model considers nominal price rigidity under different exchange rate regimes. The numerical solutions obtained are consistent with the empirical regularities documented by Broda (2004), in which output responses to shocks are smoother in floats than in pegs; in moving from pegs to floats, the rise in nominal exchange rate volatility is coupled by the rise in real exchange rate volatility; and in both exchange rate regimes, net foreign assets is the most volatile variable.     

Exchange rates of oil exporting countries and global oil price shocks: a nonlinear smooth-transition approach

This paper models logistic and exponential smooth transition adjustments of real exchange rates for six major oil-exporting countries in response to different shocks affecting oil prices. The logistic form captures asymmetric and the exponential form symmetric adjustments in regards to positive and negative oil price shocks. We chose oil-exporting countries that do not peg their exchange rates. For most countries, we detect no statistically significant non-linearities for the adjustment process of real exchange rate returns, be they asymmetric or symmetric, in response to oil supply shocks, idiosyncratic oil-market-specific shocks, and speculative oil-market shocks. Exceptions are oil supply shocks in the UK and possibly Brazil, where exchange rates respond nonlinearly, though the effects are symmetric for both countries. On the other hand, global aggregate demand shocks, which are shocks not originating directly in the oil market, have nonlinear asymmetric effects on real exchange rate returns for Canada, Mexico, Norway and Russia, and nonlinear symmetric effects for Brazil and the UK.     

The effects of exchange rate uncertainty on exports

We investigate the effects of exchange rate uncertainty on exports in the context of a multivariate framework in which a structural open economy vector autoregression is modified to accommodate multivariate GARCH-in-Mean errors, as detailed in Elder (Elder, J., 2004. Another perspective on the effects of inflation uncertainty. Journal of Money, Credit, and Banking 36, 912–928). Our measure of exchange rate uncertainty is the conditional standard deviation of the forecast error of the change in the exchange rate. We isolate the effects of exchange rate uncertainty on exports and also analyze how accounting for exchange rate uncertainty affects the response of exports to exchange rate shocks. We estimate the model using aggregate monthly data for the United States, over the flexible exchange rate period (since 1973). We use full information maximum likelihood estimation procedures and find that exchange rate uncertainty has a negative and significant effect on US exports. We also find that accounting for exchange rate uncertainty tends to strengthen the dynamic response of exports to shocks in the exchange rate and that exports respond asymmetrically to positive and negative exchange rate shocks of equal magnitude.     

THE EFFECTS OF ALTERNATIVE EXCHANGE RATE REGIMES ON REAL EXCHANGE RATE VOLATILITY: EVIDENCE BASED ON A NEW DATASET

Do alternative exchange rate regimes affect short‐term real exchange rate volatility differently? The existing empirical evidence is quite mixed with slightly more papers supporting that they do. We show that such lack of consensus is mainly due to current literature limitations regarding the measurement of real exchange rates (RERs), the identification of exchange rate regimes (ERRs), and the control for the incidence of real and nominal shocks. To address these limitations, we construct a novel monthly dataset for 63 countries over the period 1946–2007, which includes market‐determined multilateral RER and a proxy for terms of trade. We find that ERRs indeed affect short‐term real exchange rate volatility differently. While the evidence is generally consistent with Mussa's sticky prices argument, we find that for nonadvanced countries in post‐Bretton Woods there exists a “U‐shape nominal flexibility puzzle of RER.” We also find evidence of a “short‐run RER volatility puzzle.” Having controlled for the incidence of real and nominal shocks, nonadvanced countries' RER volatility remains between 25% and 150% greater than that of the advanced economies. Moreover, the key literature finding that short‐term RER volatility is higher in Bretton Woods (BW) than in post‐Bretton Woods (PBW) for industrialized countries vanishes when using market‐determined multilateral RER instead of official bilateral RER.

Trade integration and synchronization of shocks*

According to the European Commission (1990 ), closer integration leads to less frequent asymmetric shocks and to more synchronized business cycles between countries. However, for Krugman (1993 ) closer integration implies higher specialization and, thus, higher risks of idiosyncratic shocks. Drawing on the evidence from a group of transition countries, this paper tries to determine whose argument is supported by the data. This is done by confronting estimated time‐varying coefficients of supply and demand shock asymmetry with indicators of trade intensity and exchange rates. We find that (i) an increase in trade intensity leads to higher symmetry of demand shocks: the effect of integration on supply shock asymmetry varies from country to country; and (ii) a decrease in exchange rate volatility has a positive effect on demand shock convergence. The results confirm ‘The European Commission view’ and also the argument by Kenen (2001 ) according to which the impact of trade integration on shock asymmetry depends on the type of shock.     

Analyzing exchange rate uncertainty and bilateral export growth in China: A multivariate GARCH-based approach

Dramatic changes to exchange rate policy for the world's largest exporter have arguably ushered in the optimal environment for studying the effects of exchange rate uncertainty on trade. This study builds on the recent literature by using an extremely general model that measures volatility using the flexible multivariate DCC-GARCH model to analyze the impact exchange rate uncertainty has on bilateral export growth for China's ten largest export markets. All model parameters are estimated simultaneously and lagged values of uncertainty are included for a full year, where significant effects are found. The more general methods potentially overcome issues associated with inefficient two-step methods and the assumption that volatility impacts are close to instantaneous. Using a comprehensive sample that spans 1994–2017, the paper presents evidence that exchange rate uncertainty has no impact on trade with the United States, which strongly contrasts a robust finding of trade deterring impacts for almost all remaining countries. The unifying methodology is also used to analyze nominal uncertainty itself. Here, it is found that Chinese inflation may be a positive contributor to risk in an environment where many exogenous events, such as the Asian currency crisis, are associated with periods of heightened yuan uncertainty.     

Asymmetric responses of money demand to oil price shocks in Saudi Arabia: a non-linear ARDL approach

Saudi Arabia is an open oil-based economy with fixed exchange rates; therefore, it has limited monetary policy autonomy. Using non-linear autoregressive distributed lag approach, this article investigates the asymmetric effects of oil price shocks on the demand of money in Saudi Arabia over the period 1990:Q1–2014:Q4. The empirical results show evidence of positive long run but asymmetric effects of oil price shocks on the money demand. In particular, we find that the positive oil price shocks are more important than negative shocks. Therefore, two policy responses can be considered: either sustaining the fixed exchange rate regime and following an economic diversification policy or switching towards a flexible exchange rate regime to achieve price stability. In that case, the existence of a stable money demand function in Saudi Arabia is a necessary precondition for adopting a monetary policy strategy targeted to price stability using instruments like money targeting.     

The international wealth channel: a global error-correcting analysis

This article investigates empirically whether shocks to asset prices transmit into the trade balance through consumption and investment for a group of five of the world??s most industrialized countries. We refer to this transmission channel as the international wealth channel and estimate a GVAR model including 29 countries with quarterly data over the period 1981Q1?C2006Q4. Generalized impulse response functions show that after a negative stock price shock US and UK consumption decreases, followed by an improving trade balance. This pattern is also visible for France, but not for Germany and Japan. Stock price decreases are only associated with decreasing investment and an improving trade balance in the UK. For housing, we do find that a negative shock to UK housing prices decreases domestic investment and improves the trade balance. However, this pattern is not visible in the other countries. Finally, a domestic negative real exchange rate shock only has a significantly positive impact on the US trade balance.     

Does Regime Choice Affect Exchange Rate Volatility-Economic Growth Link? An Application of Panel-VAR Approach

In recent years, numerous studies demonstrated that the effect of exchange rate regimes on economic growth is influenced by several factors. However, the literature rarely takes into account the possible costs associated with improving institutional quality on the choice of exchange systems and the analysis of the effects of shocks in the case of each type of regime. Throughout this research, we analyze the extent of bidirectional shocks according to each regime and compare the shock effects accordingly. The results show that the real exchange rate is less volatile and the shock effect is lower in countries that adopt a fixed exchange rate regime while the exchange rate is more volatile and the shock is higher in countries that adopt a flexible exchange rate regime. To show the effect and persistence of shocks, we carried out a Panel-VAR regression completed by impulse response functions, VAR decomposition and Granger causality tests for 20 countries adopting the first type of exchange regime compared with 20 countries practicing an alternative exchange rate regime in the period from 1996 to 2012.     

Does Aid Mitigate External Shocks?

The authors investigate the role of aid in mitigating the adverse effects of commodity export price shocks on growth in commodity-dependent countries. Using a large cross-country dataset, they find that negative shocks matter for short-term growth, while the ex ante risk of shocks does not seem to matter. They also find that both the level of aid and the flexibility of the exchange rate substantially lower the adverse growth effect of shocks. While the mitigating effect of aid is significant in both countries with pegs and countries with floats, the effect seems to be smaller for the latter, suggesting that aid and exchange rate flexibility are partly substitutes. They investigate whether aid has historically been targeted at shock-prone countries, but find no evidence that this is the case. This suggests that donors could increase aid effectiveness by redirecting aid toward countries with a high incidence of commodity export price shocks.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

Foreign output shock in small open economies: A welfare evaluation of monetary policy regimes

We examine the impact of negative foreign output shocks, which entail negative demand side effects by lowering exports and positive supply side effects by lowering oil prices, on the welfare of non-oil producing, small open economies under five exchange rate and monetary policy regimes. We use a dynamic stochastic general equilibrium model with parameter values calibrated for Hong Kong, Israel, Singapore, South Korea and Taiwan. We find that welfare levels among the five policy regimes depend on the economy's share of oil imports in world oil consumption. Hong Kong, Singapore and Israel, which have smaller shares, maximize welfare under the Taylor rule, which targets both CPI inflation and real output. South Korea, with higher shares, and Taiwan, with more rigid prices, maximize welfare under real output targeting. CPI inflation targeting, nominal output growth targeting and fixed exchange rate regimes generate lower welfare. However, optimal monetary policy, which generates the highest welfare, gives greater weight on real output than CPI inflation.     

Optimal Monetary Policy with Vertical Production and Trade*

This paper explores the optimal monetary policy response to domestic and foreign technology shocks in an open economy with vertical structure of production and trade. We find that any stage‐specific productivity shock in one country may have a transborder spillover effect on the other country via the vertical trade. So when choosing optimal monetary rules, each monetary authority should respond to both home and foreign productivity shocks. Also, the flexible exchange rate cannot replicate the flexible price equilibrium, even under producer currency pricing, due to price stickiness in multiple stages. We also find that the existence of a transborder spillover effect depends on the currencies of price setting. Finally, vertical trade may affect the value of exchange rate flexibility under PCP and LCP setting.     

Exchange Rate Flexibility and the Effect of Remittances on Economic Growth

This paper studies the question of whether exchange rate policy affects the impact of remittances on economic growth in recipient countries. The findings indicate that more flexible exchange rate regimes are associated with a greater increase in economic growth following an increase in remittances, but also that the impact of remittances on growth is positive under a fixed regime. The results further show that the effect of remittances under a fixed exchange rate regime is positive in less financially developed countries as well, but do not provide conclusive evidence that this effect varies inversely with exchange rate flexibility in such economies as theorized; the results being sensitive to the choice of financial development indicator.     

On the feasibility of monetary union: Does it make sense to look for shocks symmetry across countries when none of the countries constitutes an optimum currency area?

Usually, a monetary union is not considered feasible between countries if the correlations of shocks are positive but weak. This may not be so if the country with the larger output gap converges to full-employment equilibrium faster than the country with the smaller gap. We argue that common monetary policy can be destabilizing when countries' responses to non-monetary shocks are perfectly symmetric with a correlation of 1 but exhibit differing investment sensitivities to the real interest rate. We use Canada, Mexico and the United States to test the feasibility of a monetary union by documenting whether: 1) gross investments in Canada and Mexico are equally responsive to the real fund rate, and 2) Canada and Mexico's output growth and inflation respond differently to US monetary policy shocks and oil price shocks. This approach implicitly dictates whether the shocks themselves are symmetric or asymmetric. Using quarterly data and SVAR methodology, we conducted two layers of analysis. We estimated SVARs for the periods 1970–2008, 1970–1990 and 1991–2008 to find that a monetary union is feasible between Canada and the US for the first two sample periods. For Canada and Mexico, we find similar responses of output growth to US monetary policy shocks. We conducted further robustness tests by estimating two identified VARs with common US variables and oil prices for Canada and Mexico to assess commonality in responses to shocks with the US. These results affirm that a monetary union is also feasible between Canada and the US.     

The choice of exchange rate regime: An empirical analysis for transition economies*

We analyze the choice of exchange rate regimes of the 25 transition economies in Europe and the CIS after 1990. The empirical results show that the traditional Optimum Currency Area considerations provide relevant guidance for the regime choices in these countries. Moreover, regime choices are influenced by inflation rates, cumulative inflation differentials, and international reserves sufficiency. That is, macroeconomic stabilization and the ability to commit to exchange rate pegs also play important roles. Large government deficits have ambiguous effects; they increase the likelihood of moving from flexible to intermediate regimes as well as that of moving from fixed to intermediate ones.     

Inflation in Open Economies with Complete Markets

This paper uses an overlapping generations model to analyze monetary policy in a two-country model with asymmetric shocks. Agents insure against risk through the exchange of a complete set of real securities. Each central bank is able to commit to the contingent monetary policy rule that maximizes domestic welfare. In an attempt to improve their country’s terms of trade of securities, central banks choose to commit to costly inflation in favorable states of nature. In equilibrium the effects on the terms of trade wash out, leaving both countries worse off. Countries facing asymmetric shocks may therefore gain from monetary cooperation.
