ARDL Approach to the Exchange Rate Overshooting in Taiwan

This paper re-examines Dornbusch’s (1976) sticky-price monetary model to exchange rate determination by employing both conventional Johansen’s (1988, 1990, 1994) maximum likelihood cointegration test and the ARDL Bound test by Pesaran, Shin, and Smith (2001) for the monthly data of Taiwan over the period 1986:01 ∼ 2003:04. Ambiguous results are found for the long-run equilibrium relationship between the NTD/USD exchange rate and macro fundamentals. With the advantage that ARDL Bound test incorporates both I(1) and I(0) series, we conclude our empirical evidence that there is no long-run equilibrium relationship between exchange rates and macro fundamentals. Moreover, for the short-run dynamic response, the result from the ARDL-UECM-MAIC (1, 10, 10, 8, 10) setting supports the overshooting of currency depreciation as pre-described by Dornbusch (1976). However, this overshooting phenomenon does not exist the current month, but one month after.JEL Classification: C32, B22, E44

Monetary policy shocks and exchange rates in Asian countries

In this paper, we empirically investigate the effects of monetary policy shocks on exchange rates in Asian countries. To do so, we use VAR models which impose sign restrictions on impulse responses to identify monetary policy shocks. We find that contractionary monetary policy shocks lead to significant exchange rate appreciation in Malaysia, the People’s Republic of China, and the Republic of Korea. However, in India, Indonesia, the Philippines and Thailand, we find either a significant depreciation or no significant effect. These results suggest that an interest rate increase (or decrease) may not necessarily shield Asian countries from exchange rate depreciation (or appreciation) pressure following a U.S. interest rate increase (or decrease).     

Households' Preferences and Exchange Rate Overshooting

Abstract

This paper uses a ‘New-Open-Economy Macroeconomic’ model to study the effect of a shock to Households' preferences on exchange rate dynamics. The special features of the model are that Households' preferences exhibit a ‘catching-up with the Joneses’ effect and that international financial markets are imperfectly integrated. Results of numerical simulations of the model demonstrate that these features imply that, in an otherwise standard ‘New-Open-Economy Macroeconomic’ model, a shock to Households' preferences can give rise to an overshooting of the exchange rate.     

Endogenous monetary policy and the liquidity effect

We compare the transmission mechanism of exogenous and endogenous monetary policies in a calibrated small open economy model with nominal and real rigidities. Under an exogenous monetary policy rule it takes implausible values of the intertemporal elasticity of substitution and the price adjustment costs to generate the liquidity and overshooting effects. Endogenous rules with strong feedback to inflation and output help to reproduce the response of the nominal interest and exchange rates to unanticipated monetary policy shocks that characterize the transmission mechanism of standard sticky price models. The liquidty and overshooting effects are always obtained when the model is augmented with a Taylor interest rate rule.JEL Classification: E32, E43Javier Andrés acknowledges support of CICYT grant SEC2002-0026.

实际汇率偏离研究述评

购买力平价说是一种基本的汇率决定理论，但影响购买力平价关系成立的短期或长期经济因素众多，从而使得实际汇率经常偏离平价关系。文章对有关文献中各种购买力平价偏离模型进行了综合分析，阐明了生产率、政府支出、货币供给、偏好需求和定价策略等基本因素作用于实际汇率的经济机制。     

Monetary Impacts and Overshooting of Agricultural Prices in an Open Economy

This article's focus is on the time adjustment paths of the exchange rate and prices in response to unanticipated monetary shocks. First, we expand the theoretical specification of the overshooting hypothesis by generalizing Dornbusch's model to include a third sector (i.e., agricultural prices). Second, we employ Johansen's cointegration test along with a vector error correction model to investigate whether agricultural prices overshoot in an open economy. The empirical results indicate that agricultural prices adjust faster than industrial prices to innovations in the money supply, affecting relative prices in the short run, but strict long-run money neutrality does not hold.     

Determining underlying macroeconomic fundamentals during emerging market crises: Are conditions as bad as they seem?

Emerging market crises are characterized by large swings in both macroeconomic fundamentals and asset prices. The economic significance of observed movements in macroeconomic variables is obscured by the brief and extreme nature of crises. In this paper we propose to study the macroeconomic consequences of crises by studying the behavior of “effective” fundamentals, constructed by studying the relative movements of stock prices during crises. We find that these effective fundamentals provide a different picture than that implied by observed fundamentals. First, asset prices often reflect expectations of improvement in fundamentals after the initial devaluations; specifically, effective depreciations are positive but not as large as the observed ones. Second, crises vary in their effect on credit market conditions, with investors expecting tightening of credit in some cases (Mexico 1994, Philippines 1997), but loosening of credit in others (Sweden 1992, Korea 1997, Brazil 1999).     

Financial Liberalization in a Small Open Economy

We address three related questions concerning financial liberalization in a small open economy. Does financial liberalization and the resulting capital inflow improve production efficiency in the domestic economy? Who benefits from financial liberalization in the long run and in the short run? Should financial liberalization be implemented gradually or hastily? Our main results are as follows. First, whether financial deregulation in one sector can improve production efficiency may depend on financial regulation in other sectors. Second, financial liberalization may have opposite welfare implications to domestic agents with different productivity in the long run. Third, although some domestic agents lose in the long run, they actually benefit from financial liberalization during the transitional process of deregulation. Finally, a gradual implementation helps achieve a smooth transition.
