The Korean stock market volatility during the currency crisis and the credit crisis

This paper studies the volatility of the Korean stock market during the Asian currency crisis of 1997–1998 and the global credit crisis of 2008–2009. We use a fad model with Markov switching heteroskedasticity, which was first proposed by Kim and Kim (1996). Using the monthly data from January 1980 to October 2009, we find that the volatility of the transitory component of the stock return, or fads, increased during the currency crisis, but did not rise much during the credit crisis. It implies that the stock price fluctuations were not driven by irrational sentiments during the recent global crisis as much as during the former crisis. However, when we consider the dollar value of the Korean stock index in order to estimate the volatility that foreign investors confront, we find that the volatility of the transitory component was raised during the credit crisis as well as during the currency crisis. That is, foreign investors experienced greater volatility than domestic investors in the recent financial market turmoil. This asymmetric volatility that domestic and foreign investors face is one of the characteristics of the credit crisis.For more detailed analysis, the same model was applied to the weekly data from January 2005 to October 2009 and provided the result that the data measured by won–dollar exchange rates were more increased than the raw data. It holds that foreign investors confronted much greater volatility than domestic investors while the stock volatility was relatively lower in the credit crisis state than in the currency crisis state.     

Interdependence of ASEAN-5 Stock Markets from the US and Japan

Abstract

During the 12 years since 1992 when people started to use the dollar as a currency in Cambodia, the share of the dollar has reached more than 70% of the total currency. This dollarization phenomenon has resulted in large seigniorage losses for the Cambodian government. The costs are estimated up to US$682 million at the end of 2004 with an additional US$61 million lost annually. Furthermore, there are many other kinds of costs caused by the side effects of seigniorage loss. Without siegiorage, some monetary, fiscal and foreign trade policies are no longer available. Worsening the distortion of income distribution is another side effect. These are major costs of dollarization over the direct seigniorage loss. The benefits of dollarization include stabilizing price levels and lowering the risk of national default during a foreign currency crisis. It is not difficult to conclude that the costs of dollarization outweigh the benefits.

There are two de-dollarization methods. One is a policy that prohibits people from using the dollar as a currency by law. The other is the policy that widens the difference of the costs and the benefits of using dollars, also by law. Either method is applicable but it seems reasonable that the method of prohibition by direct law would be more effective and efficient than the other method, since 84% of the total population exclusively uses the riel in Cambodia.

It is totally dependent on the decision of the Cambodian government whether or not a de-dollarization policy is adopted. The results of the decision, for good or ill, will rest finally with the people of Cambodia.     

Exchange rate movements and foreign direct investment (FDI): Japanese investment in Asia, 1987–2008

The paper estimates the impact of exchange rate movements on foreign direct investment (FDI). By using the panel data of Japanese FDI flows to nine dynamic Asian economies during 1987–2008, the paper finds that (i) FDI declined with a depreciation of the yen against host country currencies; (ii) it increased with exchange rate volatility; and (iii) it was little affected by the Asian financial crisis, especially when disguised financial flows were removed from the data. A novel result concerns the negative response of FDI to the third moment of monthly exchange rate changes: the volume of FDI was smaller when the distribution was positively skewed (i.e., when the yen was biased towards relatively large depreciation shocks). If skewness proxies for expected mean-reverting changes, this supports the idea that source country investors care about the future stream of revenues and returns denominated in their own currency. These results are robust, with other standard control variables having statistically significant coefficients with expected signs.     

Exchange Rate Policy and Currency Substitution: The Case of Africa's Emerging Economies

This paper examines the dynamic of currency substitution (CS) in Egypt and South Africa. The study also assesses the causal relationships of this phenomenon. There are three main CS‐related differences between the two countries. These are (1) the orientation of economic policy, (2) the degree and level of CS, and (3) the trend of CS. During the study period 1991‐2001, Egypt used the exchange rate as an anchor to its economic programme. While in the case of South Africa, the authorities directly targeted inflation. During this period, CS in Egypt started at a substantial level and experienced a steady decline. Conversely, CS in South Africa started at an insignificant level, but observed an uninterrupted increase. The results suggest that the elasticity of CS, with respect to exchange rate, of South Africa is 2.3 times that of Egypt, and that the speed of adjustment in South Africa is 5 times faster than in Egypt. Granger‐causality tests indicate a unidirectional relationship from the exchange rate to CS, in both Egypt and South Africa. The test for the interest rate differential and CS indicate that causality runs from the former to the latter in South Africa, but it runs in the opposite direction in Egypt. The study suggests that despite the cost of the exchange rate anchoring policy, it is more suitable to a high CS environment. Inflation targeting policy can be effective in achieving its objective as long as the CS is insignificant.     

Re-examination of J-curve effect for Japan,Korea and Taiwan

This study uses the generalized impulse response function from the vector error correction (VEC) model to examine whether the J-curve effect exists for Japan, Korea, and Taiwan. Both bilateral (with the US) and aggregate (with the rest of the world) cases are considered. Special attention has been given to the number of lag orders and conintegration selection and the tests of exogeneity of foreign income and structural changes. The conventional J-curve phenomenon can only be observed in Japan’s aggregate trade case. In Korea and Taiwan, where most export to import ratio increases during the currency contract period, is consistent with the theory that both economies are small.     

An Estimated Stochastic General Equilibrium Model with Partial Dollarization: A Bayesian Approach

In this paper, we develop and estimate a dynamic stochastic, general-equilibrium New Keynesian model with partial dollarization. Bayesian techniques and Peruvian data are used to evaluate two forms of dollarization: currency substitution (CS) and price dollarization (PD). The empirical results are as follow: first, it is noted that the two forms of partial dollarization are important in explaining the significance of the Peruvian data. Second, models with both forms of dollarization dominate models without dollarization. Third, a counterfactual exercise shows that by eliminating both forms of partial dollarization, the response of both output and consumption to a monetary policy shock doubles, making the interest rate channel of monetary policy more effective. Fourth, based on the variance decomposition of the preferred model (with CS and PD), it is found that demand type shocks explain almost all the fluctuation in CPI inflation, the monetary shock being the most important (39%). Remarkably, foreign disturbances account for 34% of the output fluctuations.     

Backward participation in global value chains and exchange rate driven adjustments of Swiss exports

This paper examines the effect of exchange rate movements on export volume, export revenues and propensity to export taking into account the extent of foreign value added content of exports (“backward integration”) in global value chains (GVCs). Using both product-level and firm-level panel data, our results suggest that Swiss exports (intensive margin) and the export probability (extensive margin) are negatively affected by a currency appreciation. However, this adverse effect is mitigated in sectors and firms that are more integrated in GVCs, which could be explained by the “natural hedging” of exchange rate movements. Our findings are robust to the use of different measures of natural hedging and GVC integration and also hold across various specifications and estimation methods that control for sample selection, firm heterogeneity, heteroskedastic errors and persistence in export behavior. The dynamic specifications also reveal that export hysteresis driven by a currency appreciation is a concern particularly for firms that are not established in export markets.     

Relationship regarding the demand for labor between domestic temporary and foreign workers: Korean case

With the progress of globalization, South Korea, one of the emerging industrial countries, has recently witnessed a sharp increase in the number of enterprises that employ foreigners. However, there are only a limited number of studies on the influence that such an increase has had on the labor market in the Republic of Korea. Thus, using ‘Workplace Panel Survey’ data surveyed by the Korea Labor Institute (KLI), this paper examines the relationship concerning the labor demand of an establishment between domestic temporary and foreign workers. Analysis using a bivariate Tobit model shows that a typical Korean firm attempts to employ domestic temporary and foreign workers simultaneously. Further, the empirical analysis found that any establishment that is relatively newly established and has difficulty in recruiting domestic workers hires foreign workers, but there is no evidence that establishments hire foreign workers rather than domestic temporary workers to save on the production cost.     

Restructuring of financial institutions and the corporate sector in Korea

This paper explores causes of the Korean currency crisis which started in November 1997. This paper also presents restructuring proposals and introduces the progress made so far. The urgency for quick restructuring and the necessity of the injection of money from both the government and foreign investors are emphasized. Restructuring of financial and corporate sectors should be pursued simultaneously. In the financial sector, the restructuring of banks should take precedence over other financial institutions. The key task in terms of bank restructuring involves the resolution of bad loans, recapitalization and the expedited reorganization of nonviable banks. Corporate reform is also important. Banks should play a central role in corporate workouts, especially in lowering excessive corporate debt and triggering corporate restructuring based on core competence. Transparency of corporate management, internationally accepted accounting practices, fuller disclosure requirements and stronger monitoring by minority shareholders are prerequisites for effective market discipline. Reform of ownership and governance structure are also important in enhancing managerial accountability of corporates as well as financial institutions.     

Cost heterogeneity and the destination of Japanese foreign direct investment: A theoretical and empirical analysis

This paper first of all develops a Cournot oligopolistic model with heterogeneous firms to examine each firm's choice between export-oriented foreign direct investments (FDI) and FDI to serve the host-country market. It is shown that there exist a critical level of efficiency such that all firms below that level choose the former and those above it the latter. The hypothesis is tested using firm-level data on 118,300 Japanese firms covering the entire manufacturing sector. Multinomial logit estimates strongly support our theoretical findings.     

An Investigation of the Value Relevance of Alternative Foreign Exchange Disclosures*

We demonstrate analytically and empirically that valuing a firm with foreign operations in the presence of exchange rate uncertainty requires information on the foreign operating cash flows disaggregated by currency and persistence. In particular, given consolidated earnings, investors need information on the exchange gain or loss on permanent foreign operating cash flows. We extend the model to show how the permanent foreign cash flows can be used to condition the change in the translation adjustment to make it value‐relevant; however, using the permanent foreign cash flows directly is superior for valuation purposes. The empirical tests support our hypothesis that the market response to exchange rate movements is sensitive to the relative magnitudes of revenues and costs denominated in each foreign currency in which a firm has transactions. Disclosure of cash flows by currency should enhance the valuation of firms with foreign operations.     

货币互换协议、金融市场与中国对外直接投资

基于2003-2018年169个国家的面板数据,文章利用多期双重差分方法探讨了货币互换协议对我国对外直接投资规模与密集度的影响,并通过PSM-DID方法和证伪检验对模型的稳健性进行验证。在此基础上,运用中介效应和调节效应检验方法对货币互换政策的金融市场作用机制进行分析。研究发现,货币互换协议对我国OFDI规模与密集度均有显著积极影响;预期汇率风险是货币互换协议促进我国OFDI的重要影响机制,中介传导而非调节效应是主要影响渠道,而利率市场的影响机制尚未发挥作用。在经济全球化和复杂的国际形势下,这一研究对我国进一步推动国家间金融领域深化合作和推进人民币国际化以畅通国内国际双循环具有重要参考价值。     

Asian holding of US Treasury securities: Trade integration as a threshold

This paper empirically investigates if there have been any shifts in regimes with Asian holding of US long-term Treasury securities with particular attention paid to the role of growing regional integration in trade. A panel regression estimation of eight Asian countries for 1998–2004 confirms the striking persistency of the portfolio weight of US Treasury securities. It also reveals, without a surprise, that the traditionally strong trade link with US as well as exchange rate regime and volatility of local currency bond index explain observed overinvestment in US Treasury securities deviating from what can be warranted by the market share of the US Treasury securities. What is interesting, however, is the estimated regime switches as found when examined with a threshold estimation (Hansen, 1999). We find three thresholds which divide the sample into four regimes—a decreasing persistency as intraregional trade link becomes tighter.     

The costs and benefits of exchange rate protection in China

From 2002 to 2011, China ran large surpluses in both the current and capital accounts of its balance of payments, which the People's Bank of China (PBOC) purchased and held at official foreign reserves to avoid nominal appreciation of the currency. Concurrently, with its massive purchases of foreign exchange, the PBOC compelled commercial banks to buy PBOC ‘sterilisation bonds’ and raised commercial bank reserve requirement ratios to avoid monetisation of its foreign exchange purchases and concomitant upward pressure on the price level (that is, real appreciation of the currency). Sterilising foreign exchange intervention, as China did for a decade, constitutes a violation of the implicit rules of a fixed exchange rate regime and as such can be seen as a mercantilist policy of manipulating the real exchange rate to gain, or avoid losing, international price competitiveness—what Corden (1981) termed ‘exchange rate protection’. This paper sets out the simple theory of the costs and benefits of exchange rate protection and provides back‐of‐the‐envelope estimates of their magnitude in China in the 2000s. It also explores the ‘other side of the story’, the decline in US manufacturing employment in the 2000s, which recent literature attributes to a ‘China Trade Shock’ that allegedly resulted from the US granting Permanent Normal Trade Relations (PNTR) to China in 2001. Here, it is argued that the so‐called China Trade Shock resulted from China's sterilised intervention policy, not the granting of PNTR. The implications of these competing hypotheses are considered in the conclusions.     

THE ROLE OF PRIVATE CAPITAL INFLOWS AND THE EXCHANGE MARKET PRESSURE ON REAL EXCHANGE RATE APPRECIATION: THE CASE OF TURKEY

The aim of this paper is to investigate the role of different private capital inflows and the exchange market pressure (EMP) on the real effective exchange rate (REER) appreciation of the currency in Turkey. To that end, the paper first investigates the long‐run equilibrium relationship and then employs Granger causality analysis. Results of the bounds test for cointegration within the autoregressive distributed lag (ARDL) modelling approach of Pesaran et al. (2001 ) reveal level relationship between the diverse private capital inflows, EMP and REER. Granger causality analysis suggests that there is a unidirectional causality running from all the concerned private capital inflows and EMP to REER. The ARDL model shows first that the impact of bank liabilities and portfolio investment liabilities are almost equal, high and positive. Second, foreign direct investment and workers' remittances have a negative but statistically insignificant effect. Third, EMP mitigates REER appreciation of the currency in Turkey. The empirical results suggest that speculative portfolio investment liabilities but particularly bank liabilities with short maturities should be better managed; more flexibility should be introduced to the floating exchange rate regime to avoid loss of competitiveness related with capital inflows; whereas foreign direct investments and remittances should be encouraged.     

Japanese foreign direct investment and regional trade

We examine the relationship between Japanese FDI outflows, domestic and foreign fixed investment, and the exchange rate. The results indicate that aggregate FDI outflows have been driven by investment in Japan and the exchange rate, while the geographic distribution of such investment has been influenced by foreign economic conditions. We also find that FDI outflows have a temporary impact on exports but a permanent effect on imports. We find no evidence that behavior with respect to East Asia differs from that with respect to North America or Europe.     

Monetary autonomy in selected Asian economies: The role of international reserves

With the increased financial integration of Asian countries, monetary policy takes on the additional role of maintaining the stability of the financial system along with the traditional objectives of promoting growth and employment with price stability. Given the importance and relevance of monetary policy in Asian countries, we examine monetary autonomy and its interaction with financial integration, currency regimes and international reserves for the past two decades in the following Asian countries: Thailand, Korea, Indonesia, the Philippines, and India. The empirical analysis reveals two significant and interesting findings that have policy implications. First, Thailand, Korea and Indonesia, countries that have moved towards a floating currency regime, experienced simultaneous declines in the sensitivity of their interest rates (thereby increasing monetary autonomy), while India continues to increase the sensitivity of its interest rates with a pegged exchange rate and increased financial integration. Second, in all of the studied economies, the accumulation of international reserves has contributed, to some extent, to the retention of monetary autonomy in terms of preventing the sensitivity of the interest rates from rising. We speculate that the accumulation of reserves plays the role of an anchor for monetary autonomy in emerging market economies facing a “fear of floating”.     

Speculative attacks and currency crises: The Mexican experience

By using data from the Mexican economy, this paper estimates a speculative attack model of currency crises in order to identify the role of macroeconomic fundamentals and early warning signals of a potential currency crisis. A deterioration in fundamentals appears to generate high one-step-ahead probabilities for the observed regime changes during the sample period 1982–1994. Particularly, foreign reserve losses, expansionary output, monetary and fiscal policies, an increase in inflation differentials and the share of short-term foreign currency-indexed debt, and an appreciation of the real exchange rate appear to have contributed to the speculative pressures and the associated regime changes.     

Foreign devaluation as a coordinating device of heterogeneous investors: A game‐theoretic analysis of financial contagion

This paper investigates financial contagion by extending the Morris–Shin (1998) model of financial crises. It is assumed that before a devaluation in a foreign country, home investors have only private information on the state of the home country. It is demonstrated that the occurrence of a currency crisis in the foreign country may trigger a similar crisis in the home country by coordinating heterogeneous beliefs of home investors. The model is designed to describe the Asian currency crisis of 1997.     

Money demand in China and time-varying cointegration

Many studies analyze the money demand using a (fixed coefficient) cointegrating regression model, which may not be appropriate to deal with the money demand of a transition economy like China. This paper investigates this issue using a time-varying cointegration approach based on the quarterly data from 1996 to 2009. We find some interesting results: (i) the estimates of the income elasticities are between 0.60 and 0.75, which are comparable with the previous studies; (ii) the estimated interest rate elasticity supports the argument that the overall effect of the interest rate on the money holding is weak although there are some mild evidences that it has been strengthened in recent years; (iii) the substitution effect of equity asset dominates the wealth effect, especially, during the bullish market period. Our result is robust to the alternative choices of the scale or opportunity cost variables and shows that omission of the stock prices in the money demand function would possibly yield a misspecification problem.
