Interest Rates, Exchange Rates and Present Value Models of the Current Account

This paper develops a testable intertemporal model of the current account that allows for variable interest rates and exchange rates. These additional variables are channels through which external shocks may influence the domestic current account. The restrictions from the theoretical model are subjected to present value tests using quarterly data from three small open economies. The paper finds that including the interest rate and exchange rate improves the fit of the intertemporal model over what was found in previous studies. The model predictions better replicate the volatility of current account data and better explain historical episodes of current account imbalance.     

Foreign interest rate shocks and exchange rate regimes in East Asia

Using a theoretical dynamic stochastic general equilibrium model and an empirical panel vector autoregression, we assess the transmission of foreign real interest rate shocks on the volatility of various key macroeconomic variables in nine small open economies in East Asia taking into account the role of exchange rate regimes. Both the theoretical and empirical findings confirm the hypothesis that flexible exchange rate may work as a shock absorber when the economy is hit by foreign real interest rate shocks. The findings suggest a clear trade-off between the volatility of real exchange rate and real output to foreign interest rate shocks, both the US and G7 real interest rates, where the responses of real output are mitigated in countries that have more flexible exchange rate regime.     

资本流动、货币政策与通货膨胀动态

本文建立了一个汇率对资本流动具有有限弹性的新开放宏观经济学模型.考虑到资本流动对供给面的影响,浮动汇率制度不再能完全隔离国外冲击,但是资本开放确实有助于降低国内冲击带来的经济波动.这为全球大温和提供了另一种解释.另外,本文的分析发现,一定程度的汇率干预在稳定国内冲击产生的经济波动方面比浮动汇率更优.     

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.     

Financial crises and time-varying risk premia in a small open economy: a Markov-switching DSGE model for Estonia

Under a currency board, the central bank relinquishes control over its monetary policy and domestic interest rates converge towards the foreign rates. Nevertheless, a spread between both usually remains. This spread can be persistently positive due to elevated risk in the economy. This paper models that feature by building a DSGE model with a currency board, where the domestic interest rate is endogenously derived as a function of the foreign rate, the external debt position and an exogenous risk premium component. Time variation in the volatility of the risk premium component is then modelled via a Markov-switching component. Estimating the model with Bayesian methods and Estonian data shows that the economy does not react much to shocks to domestic interest rates in quiet times but is much more sensitive during crises, and matches the financial and banking crises, which cannot be captured by the standard DSGE model.

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.     

Exchange rate dynamics in economies with portfolio rigidities

This paper studies the international transmission of productivity and monetary shocks in a general equilibrium two-country monetary model with portfolio rigidities and distribution costs in trade. The model features two types of transport costs (iceberg costs and distribution costs in terms of nontradables) and incomplete markets. The specification employed here is able to generate the domestic liquidity effect, increase in the foreign–domestic interest rate differential, and the nominal depreciation after a monetary injection. Quantitatively, the model with distribution costs as in Burstein, Neves and Rebelo (2003) performs better matching some business cycle moments, but fails to generate the high volatility of exchange rates observed in the data.     

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.     

对外开放和经济波动的关联性检验——中国和东亚新兴市场国家的案例

本文运用研究非对称性冲击问题的实证方法考察和比较了东亚4国(韩国、印尼、泰国和中国)在经济开放过程中内外金融资源的相对价格——实际利差的变化及由此引起的宏观经济(产出、货币和银行信贷)的波动特征。这一研究的政策意义在于通过区分外部因素的基本面(mean)变化和突发性的波动(volatility)对本国经济所产生的不同性质的溢出效应(spillover),为政府制定不同的针对性措施提供理论根据。通过引入非对称“时变波动”(asymmetrictimevaryingvolatility)特征的二元EGARCHVAR实证模型,论文得到了三个主要结论第一,虽然为维持名义汇率的稳定,各国政府都积极地干预外汇市场,由此影响了当期内外利差的收敛,但包括中国在内的4个国家金融的实际开放程度都在不断加大。第二,除上世纪90年代国际资本移动的鼎盛阶段外,各国的经济波动并不是由外部冲击直接带来的,而是国内经济的不确定因素导致的。第三,比较各国经济波动特征,可以发现汇率制度、金融市场的开放程度以及资本市场的发展状况对经济波动有很大的影响。     

Transmission of monetary policy and exchange rate shocks under foreign currency lending

This paper analyses the differences in reaction of domestic and foreign currency lending to monetary and exchange rate shocks, using a panel VAR model estimated for the three biggest Central and Eastern European countries (Poland, the Czech Republic and Hungary). Our results point toward a drop in domestic currency loans and an increase of foreign currency credit in reaction to monetary policy tightening in Poland and Hungary, suggesting that the presence of foreign currency debt weakens the transmission of monetary policy. A currency depreciation shock leads to an initial decline in foreign currency lending, but also in loans denominated in domestic currency as central banks react to a weaker exchange rate by increasing the interest rates. However, after several quarters, credit in foreign currency accelerates, indicating that borrowers start using it to substitute for depressed domestic currency lending.     

Interest Parity,Monetary Policy and the Volatility of Australian Short-Term Interest Rates: 1978–1982*

The period since the introduction of the Treasury note tender in December 1979 has been characterized by increased variability of Australian short-term interest rates. Using a methodology suggested by Evans, the increase in variability of the 90-day commercial bill rate is decomposed into that attributable to domestic monetary policy, seasonal influences, covered international interest rate movements and other miscellaneous influences. The results suggest that after December 1979 Australian short-term interest rates became more sensitive to surprises in the domestic monetary base, covered Eurodollar rate surprises and seasonal influences. Increased volatility of the covered Eurodollar rate also contributed to increased variance of domestic rates.     

Foreign Debt,Foreign Direct Investment and Volatility

We investigate how foreign debt and foreign direct investment (FDI) affect the growth and welfare of a stochastically growing small open economy. First, we find that foreign debt influences the growth of domestic wealth by lowering the cost of capital, while FDI affects the country's welfare by providing an additional source of permanent income. Second, a decline in domestic investment may improve domestic welfare as FDI replaces the gap. Even when the welfare deteriorates, its magnitude is mitigated, leaving more room for discretionary fiscal policy. Third, a fiscal policy aimed to stabilize domestic output fluctuations needs to be conducted not to crowd out the welfare benefit of FDI too much. Fourth, an economy with both types of foreign capital experiences wider welfare swings by external volatility shocks than the one with foreign debt alone, while the welfare effects from domestic volatility shocks are mitigated. The welfare effects of fiscal shocks are much smaller with both types of foreign capital. Lastly, the first-best labor income tax covers the government absorption by the labor's share of total output, and the capital income tax covers the rest. Investment is penalized or subsidized depending on the social marginal cost-gain differential.     

Time-Varying Behavior and Asymmetry in EMS Exchange Rates *

This paper explores the time-varying behavior of five EMS exchange rates namely, the Belgian Franc, Dutch Guilder, French Franc, Italian Lira and the Spanish Peseta vis-à-vis the Deutschemark from 1979 to 1998. The returns were examined using the Sign- and Volatility-Switching GARCH model, which is capable of accounting for potential asymmetries and the reversals in a series' volatility structure. The results point to significant sensitivities of the conditional variances of the French franc, the lira and the peseta to adverse shocks but notable responsiveness to favorable shocks by those of the other rates. Although asymmetry in the volatility structure of all rates is found in the period prior to Germany's reunification in 1990, it vanishes thereafter. Volatility persistence for all rates is noticeable in the first period but becomes more pronounced in the second, [F23, F31]     

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.     

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 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.     

Currency Boards when Interest Rates are Zero

In a fixed exchange rate system, any expectation that the peg may be abandoned will normally be reflected in an interest rate differential between instruments denominated in domestic and anchor currencies: the possibility of a revaluation will drive domestic interest rates below those in the anchor currency, for example. However, when interest rates are close to the zero lower bound, there is limited scope for exchange rate expectations to be reflected in interest rate differentials. Here we introduce a new mechanism, based on the central bank balance sheet, which works to bring about equilibrium in currency markets even when interest rates are zero. An expectation of exchange rate appreciation will cause foreign exchange reserves to swell, increasing the cost to policy‐makers of allowing an appreciation and, therefore, lowering the likelihood of the fixed exchange rate being abandoned. Under normal circumstances, this channel reinforces the equilibrating effect of interest rate differentials. When interest rates cannot adjust only this channel operates, implying that much larger changes in reserves are required to equilibrate currency markets. We develop a simple model to illustrate these arguments and find support for the predictions of the model using data for Hong Kong, the world's largest economy with a currency board.     

Structural VAR models for Malaysian monetary policy analysis during the pre- and post-1997 Asian crisis periods

This article conducts an in-depth investigation into building a Structural Vector Autoregression (SVAR) model and analysing the Malaysian monetary policy. Considerable attention is paid to: (i) the selection of foreign, policy and target variables; (ii) establish identifying restrictions and improve the estimates of impulse response functions; (iii) assess the importance of intermediate channels in transmitting monetary policy mechanism; and (iv) the way in which the 1997 Asian financial crisis affected the working of monetary policy. Malaysia is an interesting small open economy to study because, following this crisis, the government imposed capital and exchange rate control measures. The overall results suggest that the crisis and the subsequent major shift in the exchange rate regime have significantly affected the Malaysian ‘Black Box’. In the pre-crisis period, domestic variables appear to be more vulnerable to foreign monetary shocks. Further, the exchange rate played a significant role in transmitting the interest rate shocks, whereas credit and asset prices helped to propagate the money shock. In the post-crisis period however, asset prices play a more domineering role in intensifying the effects of both interest rate and money shocks on output, and the economy was insulated from foreign shocks.     

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.
