Financial market integration,exchange rate policy,and the dynamics of business and employment in Korea

We study the consequences of different degrees of international financial market integration and exchange rate policies in a calibrated, medium-scale model of the Korean economy. The model features endogenous producer entry into domestic and export markets and search-and-matching frictions in labor markets. This allows us to highlight the consequences of financial integration and the exchange rate regime for the dynamics of business creation and unemployment. We show that, under flexible exchange rates, access to international financial markets increases the volatility of both business creation and the number of exporting plants, but the effects on employment volatility are more modest. Pegging the exchange rate can have unfavorable consequences for the effects of terms of trade appreciation, but more financial integration is beneficial under a peg if the economy is subject to both productivity and terms of trade shocks. The combination of a floating exchange rate and internationally complete markets would be the best scenario for Korea among those we focus on.

The stock market and the ringgit exchange rate: a note

This paper presents and tests an augmented monetary model that includes the effect of stock prices on the bilateral exchange rates. The model is applied to the ringgit/US dollar (RM/US) and ringgit/Japanese yen (RM/JY) exchange rates. The empirical analysis is conducted by the Johansen method of cointegration. Using the data from the recent float that ends with 1996:Q4, the study is motivated, among others, by an interesting preliminary finding that although the augmented monetary model is cointegrated, it is subject to parameter instability and that the parameter time dependency can be attributed at least partly to a particular subset of the variables in the system including stock prices. We find that a restricted VAR model which imposes exogeneity restrictions on I(1) variables, such as stock prices, among others, exhibits both cointegration and parameter stability. In addition, we demonstrate that exchange rate adjusts to clear any disequilibrium in the long-run relationship. The empirical findings tend to suggest that the equity market is significant in affecting the exchange rate and in explaining at least in part the parameter instability evidenced in the cointegrating system. Hence, we conclude that models of equilibrium exchange rate should be extended to include equity markets in addition to bond markets.     

Financial integration and innovation in Europe

The creation of an internal market for financial services by the European Union, along with technological changes in communications and data management, will have a strong impact on banking and financial markets in Europe. This paper presents a selective review of discussions concerning the resulting processes of adjustment and their outcomes. Topics covered include effects on cost efficiency, competition production and trade patterns, and the dynamics of financial regulation in the open, integrated economy.     

The US tech pulse,stock prices,and exchange rate dynamics: Evidence from Asian developing countries

This paper empirically investigates the economic relationship between the US and Asian economies after the Asian currency crisis in Indonesia, Korea, the Philippines, Singapore, and Thailand, employing a cointegration methodology. Based on the empirical results, we conclude that the interdependence between the US and these Asian economies has intensified especially in information technology industries, and that their stock markets are integrated. On the other hand, the relationship between the domestic stock and foreign exchange markets is found to have a negative sign, interpreted by portfolio balance approach, in Indonesia, Korea, and Thailand. This result implies that the exchange rates of these countries are relatively vulnerable to fluctuation in international portfolio investments.     

The co-movement of stock markets in East Asia: Did the 1997–1998 Asian financial crisis really strengthen stock market integration?

This paper examines the integration and causality of interdependencies among seven major East Asian stock exchanges before, during, and after the 1997–1998 Asian financial crisis. For this purpose, we use daily stock market data from July 1, 1992 to June 30, 2003 in local currency as well as US dollar terms. The data reveal that the relationships among East Asian stock markets are time varying. While stock market interactions are limited before the Asian financial crisis, we find that Hong Kong and Singapore respond significantly to shocks in most other East Asian markets, including Shanghai and Shenzhen, during this crisis. After the crisis, shocks in Hong Kong and Singapore largely affect other East Asian stock markets, except for those in Mainland China. Finally, considering the role of the USA shows that it strongly influences stock returns in East Asia – except for Mainland China – in all periods, while the reverse does not hold true.     

Real exchange rate determination in eastern Europe

This paper develops a simple theoretical model of exchange rate determination in a transitional economy. The distinguishing feature of the model is the retention of market failures pertaining to the production and consumption of nontradable goods and, therefore, the likelihood of real exchange rate appreciation. Using this framework, the econometric tests are performed for the Czech Republic, Slovenia, Poland, and Hungary, and appropriate macroeconomic and exchange rate policies are recommended to support further liberalization and development of the foreign exchange market.     

Fundamental equilibrium exchange rates and exchange rate dynamics

This paper examines whether there is a tendency for actual exchange rates to return to their fundamental equilibrium exchange rates (FEERs) when the latter are estimated based on popular exchange rate models. Co-integration tests and unit root tests are applied. There is little evidence that the exchange rates of Japan and Germany have a reversion to the purchasing-power-parity (PPP) rates or Williamson's FEERs or the underlying external and internal balance (UEI) FEERs.     

Forward market intervention,endogenous speculation,and exchange rate variability

In a stochastic macroeconomic model, this paper studies the desirability of intervention in the forward exchange market to stabilize the spot rate from the short-run and long-run perspectives. Behavior of forward speculation is endogenized in the light of the Lucas critique. Numerical simulation suggests that such intervention is much less desirable in the long-run than in the short-run. Only when domestic monetary disturbance is present, such intervention may be desirable both in the short-run and in the long-run, provided that price adjustment is sufficiently elastic.     

从利率变动看中国股市

2005年股改以来的中国股市新高不断。股指从2006年初至今翻了5倍。2007年来的5次加息不但没有对股市产生过多的负面影响,股指却在每次加息公布的第二交易日有所攀升。本文对这一现象的原因以及利率调整的有效性问题加以分析,认为投资者的非理性因素即羊群效应以及证券市场投资渠道少和股票市场供给不足是加息对股市的影响不明显的主要原因。

Fiscal announcements and real exchange rate dynamics

This paper examines the dynamic impact of anticipated government spending on real exchange rates in a general-equilibrium framework. I show that an increase in government spending causes persistent movements in real exchange rates, and that the time profile of real exchange rates differs with patterns of government spending. Hence, one of the explanations for the misalignment and excess volatility of real exchange rates during the flexible exchange rate system may be volatile changes in government spending.     

中国利率市场化改革的路径选择

以麦金农—肖学派为核心的传统金融发展理论指出,只有实行以利率市场化为核心的金融自由化道路,才能使发展中国家摆脱金融抑制,走上金融发展与经济增长的良性循环道路。以这一理论为基础,中国从1993年开始走上了利率市场化改革的道路,经过10多年的努力,到目前为止,中国已经在多个领域,多个层次初步实现了利率市场化。可以说,中国的利率市场化改革已经走在了金融自由化进程的前边。     

Implicit exchange regimes in Central and Eastern Europe: a first exploration

This paper attempts to identify implicit exchange rate regimes for currencies of the Central and Eastern European Countries vis-à-vis the euro. To that end, we apply a sequential procedure that considers the dynamics of exchange rates to data covering the period from 1977:01 to 2006:02. Our results would suggest that implicit bands have existed in many subperiods for almost all currencies under study. Once we detect de facto discrepancies between de facto and de iure exchange rate regimes, we propose a model in order to explain these decisions. Our results suggest a positive association between the previous inflation rate and the probability of a peg with the euro, and a negative association with past unemployment rate.

Asymmetric dynamics in stock market correlations: Evidence from Japan and Singapore

This paper uses the asymmetric dynamic conditional correlation model developed by Cappiello et al. (2006) to analyze the correlation between the Japanese and Singaporean stock markets and makes two principal findings. First, it finds that financial integration has advanced because of the Japan–Singapore Economic Partnership Agreement, thereby strengthening the bidirectional relationship between Japan and Singapore. Second, it demonstrates empirically that the weight of Asian stocks in portfolios within the Asian region has increased since the global financial crisis, again strengthening the relationships among Asian region economies.
