The impact of output and exchange rate volatility on fixed private investment: evidence from selected G7 countries

This study examines the impact of shocks to exchange rate and output uncertainty (volatility) on real private fixed investment (FI) in Canada, Germany, the United Kingdom and the United States. The analysis is conducted using vector autoregressive models that contain the price level, real output, the volatility of real output, the real exchange rate, the volatility of the real exchange rate, an interest rate and FI. The results yield important public policy implications with regard to the impact of output volatility of FI. Our analysis indicates that volatility shocks, measured as output volatility or exchange rate volatility, do not have a significant impact on FI for any country in our study.     

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.

Modelling the impact of central bank intervention on exchange rate volatility under inflation targeting

This article empirically investigates the effect of central bank’s foreign exchange interventions on the level and volatility of the Uganda shilling/US dollar exchange rate (UGX/USD) under an inflation-targeting regime. Utilizing daily data spanning the period 1 September 2005, to 31 December 2015, we estimate a foreign exchange intervention model within a GARCH theoretic framework. Empirical results indicate that foreign exchange interventions have had mixed impact on the volatility of the exchange rate. We find that inflation targeting is capable of curbing temporary exchange rate shocks. Empirical results indicate that while order flow is capable of reducing exchange rate volatility, an increase in the operating target rate, the 7-day interbank rate tends to exacerbate exchange rate volatility. Our empirical results are robust to alternative model specifications. We argue that inflation targeting is an effective monetary policy tool for curbing exchange rate volatility.     

Nominal and real volatility as determinants of FDI

This article examines the role of country-specific sources of output and interest rate or exchange rate volatility in driving Foreign Direct Investment (FDI) activities. Building on a dataset with bilateral FDI flows among 24 Organization for Economic Co-operation and Development (OECD) economies over the period 1985–2007, we find that nominal and real volatility strongly deter foreign investments. Output and exchange rate volatility matter in particular for the decision whether to invest in a foreign country in the first place. Interest rate volatility mainly influences the amount of foreign investments.     

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.     

Macroeconomic dynamics in Macedonia and Slovakia: Structural estimation and comparison

This paper estimates a structural macroeconomic model using data for Macedonia and Slovakia to characterize possible challenges Macedonia can face concerning macroeconomic stabilization during its transition process. A comparison of the estimated model parameters suggests that, in Slovakia, the output gap is less sensitive to real interest rate movements and prices experience greater inertia. The estimated monetary policy reaction functions show Macedonia and Slovakia as inflation targeters, with Macedonia as the more conservative one, despite its officially applied exchange rate targeting regime. The differences in the estimated parameters imply differing transmission mechanisms for Macedonia and Slovakia. Consequently, the variance of domestic variables in Slovakia is most influenced by monetary policy shocks, while there is no single dominating shock explaining the volatility of Macedonia's macroeconomic variables. The exchange rate shock, the monetary policy shock and the demand shock are jointly important in determining the volatility of Macedonia's variables. The model simulations indicate that Macedonia experiences lower output gap and inflation volatility than Slovakia. This comes, nevertheless, at the cost of higher interest rate and real exchange rate volatility in Macedonia, which could be an indication of more volatile financial markets with possible negative implications for financial stability.     

Optimal exchange rate policy for a small oil-exporting country: A dynamic general equilibrium perspective

This paper examines the choice of optimal exchange rate regime for an oil-exporting small open economy using a welfare-based model. The paper extends the standard New Keynesian Small Open Economy model to include three countries: a small oil-exporting country and two large foreign countries. The model also features three sectors: traded, non-traded, and primary-commodity (crude-oil). The sources of uncertainty are random monetary (demand), productivity (real), and real oil price (supply) shocks. Despite the absence of a non-oil traded sector in this primary-commodity economy, the welfare analysis suggests that flexible exchange rate regimes can reduce external shocks and consumption volatility given certain caveats about pricing-schemes. The analysis also suggests that a basket peg is more welfare-improving than a unilateral peg, as higher volatility of the anchor currency reduces consumer welfare.     

The effects of government spending shocks on the real exchange rate and trade balance in Turkey

The aim of this study is to investigate the effects of government spending shocks on the real exchange rate and foreign trade balance in Turkey for the period of 2002:01–2012:04 within a structural VAR framework. The analysis shows that a positive shock to the government spending tends to induce real exchange rate appreciation and deterioration in trade balance. We also find that the composition of the government spending matters. Although shocks to the government nonwage consumption generate an appreciation in the real exchange rate and worsening of the trade balance, the effects of government investment shocks remain insignificant. Furthermore, the analysis demonstrates that shocks to government spending are associated with a rise in taxes, which is indicative of a spending-driven tax adjustment process in Turkey.     

Exchange rate volatility and export growth in Nigeria

This article examines the impact of exchange rate volatility on Nigeria's exports to its most important trading-partner–the United States over the quarterly period January 1980 to April 2001. Using cointegration and vector error correction (VECM) framework, empirical tests indicate the presence of a unique cointegrating vector linking real exports, real foreign income, relative export prices and real exchange rate volatility in the long run. Furthermore, the results show that increases in the volatility of the real exchange rate raise uncertainty about profits to be made which exert significant negative effects on exports both in the short- and long-run. Our results also show that improvements in the terms of trade (represented by declines in the real exchange rate) and real foreign income exert positive effects on export activity. Most importantly, we found that the trade liberalization and economic reform policies implemented in the post-1986 structural adjustment period contributed to Nigeria's export performance. Overall, our findings suggest that Nigeria's exporting activities can be further boosted by policies aimed at achieving and maintaining a stable competitive real exchange rate.     

INTERNATIONAL BUSINESS CYCLES IN EMERGING MARKETS

I document cyclical behavior of real exchange rates (RERs) in emerging and developed economies: stronger RER procyclicality coincides with larger relative volatility of consumption and more countercyclical trade balance. I then reevaluate the sources of fluctuations in emerging economies using an international business cycle model estimated to match the behavior of the RERs. Interest rate shocks, without any frictions, account for most of output fluctuations. This result is driven by imperfect substitution between domestic and foreign goods, which dampens the impact of trend shocks and accentuates the impact of interest rate shocks on output and consumption.     

Is the exchange rate a shock absorber or a source of shocks? Evidence from the U.S.

We examine the stabilization role of the exchange rate in the U.S. economy using a factor augmented vector autoregression model. We find that exchange rate shock explains a large fraction of the variation in exchange rate and transmits major disturbances to the real economy. Further, we find that demand and supply shocks explain less than a quarter of the exchange rate movement. We provide robust evidence that although the exchange rate plays some role as a shock absorber, its role as an independent source of shocks is more dominant for the U.S. economy. The foreign exchange market breeds its own shocks which are destabilizing not only to the value of the dollar but to the overall economy as well. Our results suggest that policymakers need to take foreign exchange market fluctuations into account when making macroeconomic policy decisions.     

The effects of exchange rate volatility on exports: evidence from Armenia

The article examines how the volatility of exchange rate affected Armenia’s export to its main trading partner, Russia, in the period from January 2007 to February 2016. Along with real foreign income and competitiveness, the exchange rate volatility is considered as a determinant of real export. The estimation results indicate that the exchange rate volatility has negative significant effects on real export both in the long run and in the short run.     

Price and liquidity puzzles of a monetary shock: Evidence from indebted African economies

Price and liquidity puzzles have been identified as two major counterintuitive findings arising from monetary shocks. We investigate their presence in eleven African countries, using a dynamic stochastic general equilibrium model designed for indebted small open-economies. Our simulations reveal that the majority of African countries report a price puzzle whereas only three countries exhibit liquidity effect. In many of the sampled countries, a positive money growth shock drives interest rates up, but consumption and output fall in contrast to the conventional view. External debt increases in response to money growth shock, exchange rate appreciates and inflation falls. Money growth shocks are transmitted to the economy through the exchange rate channel when uncovered interest rate parity condition holds. Our findings therefore appear to suggest that monetary policy in Africa should prioritize foreign debt stabilization by reacting more to output gap than to inflation.     

Foreign output and price shocks and macroeconomic activity in Korea

This paper examines the effects of foreign output and price shocks on output and the price level in Korea. The framework is a nine variable VAR model which includes output, price level, interest rate, real exchange rate, money supply, government expenditures, government debt, and foreign output and price variables. Foreign output and price effects are evaluated through computation of variance decompositions and impulse response functions. The variance decompositions indicate significant effects of foreign output on domestic output and significant effects of foreign prices on domestic output and the price level. The impulse response functions indicate positive short-run effects of foreign output on domestic output but insignificant effects on the price level while foreign price shocks have significant negative effects on output and significant positive effects on the price level for approximately two years. The results indicate the importance of including foreign shock variables when modeling the Korean economy.     

Forward Rates,Interest Rates,and Expectations Under Alternative Exchange Rate Regimes*

A model comprising spot and forward foreign exchange markets and a domestic credit market is used to examine the trade-off between volatility in the nominal exchange rate and domestic interest rate. It also shows how a slowly crawling spot rate can raise interest rate volatility and the amplitude of reserve flows. Finally, the paper extends a finding by Driskill and McCafferty that the exchange rate effects of external shocks are differently affected by the responsiveness of speculation to expected profits; high responsiveness makes the spot exchange rate more sensitive to foreign financial shocks but less sensitive to trade balance shocks.     

Exchange Rate Volatility and Output Volatility: A Theoretical Approach*

This paper makes an attempt to determine the factors influencing exchange rate and exchange rate uncertainty, as well as output and output variability. In the context of a small open economy under flexible exchange rates regime it is found that the level both of exchange rate and output is affected by monetary and inflationary shocks, as well as shocks in government spending, output, and trade balance. Further, the uncertainty of exchange rate and output is associated positively with the uncertainty of all shocks while the contemporaneous occurrence of selected shocks imposes either a positive or negative impact on exchange rate and output volatility. Finally, it is shown that the effect of the determinants either of exchange rate volatility or output volatility is very sensitive to the parameter values.     

Do sticky prices increase real exchange rate volatility at the sector level?

We introduce the real exchange rate volatility curve as a useful device to understand the relationship between price stickiness and the fluctuations in Law of One Price deviations. In the presence of both nominal and real shocks, the theory predicts that the real exchange rate volatility curve is a U-shaped function of the degree of price stickiness. Using sector-level US–European real exchange rate data and frequency of price changes, we estimate the volatility curve and find the predominance of real effects over nominal effects. Good-by-good variance decompositions show that the relative contribution of nominal shocks is smaller at the sector level than what previous studies have found at the aggregate level, consistent with significant averaging out of good-specific real microeconomic shocks.     

The impacts of economic sanctions on exchange rate volatility

This research empirically analyzes the impact of various instruments of economic sanctions on official exchange rate volatility by employing data from a panel of 23 target countries covering the period 1996–2015 and using the Least Squares Dummy Variable Corrected (LSDVC) model. Our findings suggest that economic sanctions do significantly influence the target countries’ exchange rate volatility. Specifically, we are able to see different sanction present its different effects on exchange rate volatility. Furthermore, the robustness evidence of the eliminating country as Iran, eliminating variable of political ideology, intercepting time period, cross-sectional regression analysis, using real exchange rate volatility as proxy variable and a new sanctions database, are basically consistent with the previous finding. Overall, our empirical findings offer implications for those sanctioned countries about how to stabilize their exchange rate when facing sanctions.     

The effects of macroeconomic factors on South African agriculture

Significant research efforts have been devoted to understanding the effects of macroeconomic factors on the agriculture sector. Analysing the sources of volatility in the industry is critical for designing appropriate policies to stabilize agricultural markets, reduce poverty and increase economic growth. Agriculture is a competitive sector with prices that are more flexible than those in nonagricultural sectors. This article uses annual data over the 1957–2004 period and a vector error-correction model in investigating the dynamic effects of exchange rates, money supply and other macroeconomic variables on the agricultural sector in South Africa. Overall, real exchange rates, interest rates, inflation and money supply (M3) shocks have significant and persistent impacts on agricultural output, prices received by farmers and farm input prices. M3 and interest rate shocks tend to put agriculture in a cost-price squeeze. Agricultural price movements are a source of macroeconomic instability in the country. Real exchange rate shocks shift relative prices in favour of agriculture in the long-run, thereby, boosting farm incomes and accelerating poverty reduction in the country.     

Monetary shocks,exchange rates and trade balances: Evidence from inflation targeting countries

This paper investigates the relationship among monetary policy shocks, exchange rates and trade balances in five Inflation Targeting Countries (ITCs). The investigation is based on Structural Vector Error Correction Models (SVECMs) with long run and short run restrictions. The findings reveal that a contractionary monetary policy shock leads to a decrease in price level, a decrease in output, an appreciation in exchange rate, and an improvement in trade balance in the very short run. Our findings contradict the findings of price, output, exchange rate and trade puzzles that have been found in many empirical studies. Furthermore they are consistent with the theoretical expectations regarding the effect of a contractionary policy. The only long run restriction that we imposed on our models is that money does not affect real macroeconomic variables in the long run, which is consistent with both Keynesian and monetarist approaches.
