Price Common Volatility or Volume Common Volatility? Evidence from Taiwan's Exchange Rate and Stock Markets

This paper investigates the common volatility structure of stock and exchange rate markets of Taiwan. The two markets are often linked together and we are interested in knowing whether price or volume is a good proxy to pursue this issue. We claim that Taiwanese government interventions distort the timing of conventional price volatility clustering in the two markets. The unrestricted trading volumes reveal more information regarding the market than price. We find that common volatility does exist in the stock and exchange markets and this fact is uncovered more easily by using trading volume than by using prices.     

Exchange Rate Volatility, Nominal Rigidities, and Persistent Deviations from PPP

It is shown how nominal exchange rate volatility can cause persistent deviations in the real exchange rate. The key to nominal rigidities is a capital market imperfection implying that agents cannot hedge perfectly against consumption risks. As a consequence, nominal changes have real effects by both affecting the ex post real purchasing power of savings and by affecting the ex ante incentives in savings and labor supply. The consequences of exogenous changes in the nominal exchange rate are considered in an OLG version of a two sector small open economy with competitive product and labor markets.J. Japan. Int.

Inflation Targeting in ASEAN‐10

The paper addresses the empirical question of whether economies that do not systematically target inflation (non‐inflation targeters) experience higher exchange rate volatility as compared with inflation targeters in 10 countries of the Association of Southeast Asian Nation (ASEAN) from 1990 to 2010. The paper examines the role of real exchange rate, exchange rate volatility and the reaction functions of central banks using dynamic panel estimation techniques. The results indicate that the output gap offers more useful information than the inflation gap in setting interest rates for inflation targeters, implying that the real term is more important than the nominal term. In turn, this suggests that an increase in interest rate can be wielded swiftly to reduce real gross domestic product and suppress inflation. The real exchange rate appears as a weaker determinant in setting interest rates for non‐inflation targeters. Inflation targeters experienced lower exchange rate volatility compared with non‐targeters in the ASEAN, which implies that implementation costs to their domestic economies may be marginally lower. Meanwhile, the non‐targeters follow a mixed strategy as both the inflation and real exchange rate are used as instruments to set the interest rates.     

Real effective exchange rates and purchasing-power-parity convergence: Empirical evidence for Denmark, 1875–2002

Abstract

Official nominal and real effective krone-rate indices compiled by the Danmarks Nationalbank are available only for the most recent decades. This article makes an attempt to overcome this data shortage by constructing long historical time-series indices of nominal and real effective krone rates for the period 1875–2002. Furthermore, the article presents a first exploratory examination of the empirical evidence regarding long-run relative purchasing-power-parity (PPP) convergence based on univariate unit-root testing of the two new long time-series indices for the real effective krone rate, with respectively consumer prices and wholesale prices as deflators. The fastest mean reversion towards relative PPP seems to have occurred in those periods where Denmark has pursued a fixed-exchange-rate policy vis-à-vis the majority of its trading partners and thus in those periods with the lowest volatility in the nominal effective krone rate.     

Surfing the waves of globalization: Asia and financial globalization in the context of the trilemma

Using the “trilemma indexes” developed by Aizenman et al. (2010) that measure the extent of achievement in each of the three policy goals in the trilemma—monetary independence, exchange rate stability, and financial openness—we examine how policy configurations affect macroeconomic performances, with focus on the Asian economies. We find that the three policy choices matter for output volatility and the medium-term level of inflation. Greater monetary independence is associated with lower output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated if a country holds international reserves (IR) at a level higher than a threshold (about 20% of GDP). Greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation rate. We find that trilemma policy configurations affect output volatility through the investment or trade channel depending on the openness of the economies. Our results indicate that policy makers in a more open economy would prefer pursuing greater exchange rate stability while holding a massive amount of IR. Asian emerging market economies are found to be equipped with macroeconomic policy configurations that help the economies to dampen the volatility of the real exchange rate. These economies’ sizeable amount of IR holding appears to enhance the stabilizing effect of the trilemma policy choices, and this may help explain the recent phenomenal buildup of IR in the region.     

Influence of the Banks' Money Mediation Behavior on the Monetary Policy: A Study of Korean Case

Abstract

This paper analyses how financial institutions' arbitrary intermediation behaviors, including adjustments in bank lending and deposit rates, influence monetary policy transmission channels. For the analysis, we develop a New Keynesian Dynamic Stochastic General Equilibrium (NK DSGE) model with parameters estimated to fit the Korean conditions. The role of banks is subsequently examined by classifying monetary policy transmission channels (real rate channel, nominal debt channel, financial accelerating channel, and banking attenuator channel). A notable part of this analysis is the inclusion of the banking sector in the model specifically with the intent to study transmissions from the financial sector to the real economy. This paper follows this line of inquiry with recent research in mind. Empirical analysis verifies the existence of the banking attenuator effect in Korea, which means banks act to reduce the effect of monetary policies. This indicates that if financial intermediaries strengthen arbitrary adjustment behaviors of lending and deposit rates, the effect of the monetary policy intended to relieve volatility in the business cycle may not be as high as expected.     

Exchange rate volatility,international trade and labour demand

The purpose of this study is to assess under what conditions exchange rate volatility generates a positive effect on an exporting firm’s labour demand. As the exchange rate volatility increases, so does the value of the export option, provided that firms are flexible with respect to international trade. Higher volatility increases the potential gains from trade and can increase the demand for labour. The firm’s trade flexibility can be interpreted as a real hedging strategy when financial markets are incomplete. In many newly industrializing countries and emerging economies financial markets are imperfect or risk sharing markets are just starting to develop at a rather slow pace.     

Chinese exchange rate and price effects on G3 import prices

This paper explores the degree of price and exchange rate interdependence between China and the G3 (US, Japan and the Euro-zone) by undertaking a VAR based shock analysis. A GARCH framework is also employed to derive the conditional variances to uncover the extent of volatility transmission. We address two key issues. First as there have been concerns about low value-added cheap Chinese goods flooding G3 markets, we attempt to measure the impact of Chinese prices on G3 import prices. Second, we focus on the transmission of exchange rate shocks – a subject which we approach by examining shocks in China's bilateral exchange rate with each of these major trading partners (the US, Japan and the Euro Area). Our results indicate that reduced import prices from China are the channel through which aggregate domestic prices in the G3 remain depressed, while the impact of the RMB exchange rate with G3 currencies appears less powerful. This finding implies that the Chinese authorities’ RMB exchange rate policy is relatively unimportant and, in particular, that a revaluation of the RMB would not do much to reduce the US trade deficit. In terms of volatility spillover, the relatively flexible RMB exchange rate against the Euro results in RMB-EUR volatility having a stronger influence than the more tightly controlled RMB-USD rate on the volatility of Chinese export prices.     

Monetary policy transmission and macroeconomic policy coordination in Pacific island countries

During the global financial crisis, central banks in Pacific island countries eased monetary policy to stimulate economic activity. Judging by the ensuing movements in commercial bank interest rates and private sector credit, monetary policy transmission appears to be weak. This is confirmed by an empirical examination of interest rate pass‐through and credit growth. Weak credit demand and under‐developed financial markets seem to have limited the effectiveness of monetary policy, but the inflexibility of exchange rates and rising real interest rates have also served to frustrate the central banks' efforts despite a supporting fiscal policy. While highlighting the importance of developing domestic financial markets in the long run, this experience also points to the need to coordinate macroeconomic policies and to use all macroeconomic tools available in conducting countercyclical policies, including exchange rate flexibility.     

Information arrival,interest rate differentials,and yen/dollar exchange rate

This paper examines the effects of interest rate differentials as inflowing information into the forex market on the yen/dollar exchange rate and unexpected trading volume by a structural VAR model. The impulse responses show that the short-term interest rate differential affects the exchange rate through (a) UIP with little change in unexpected trading volume, and (b) different expectation revisions at different points in time with a high transaction volume. The effects of long-term interest rate differential on the exchange rate appear instantaneous with high trading volume, reflecting instantaneous reshuffling in international portfolio holdings of long-term assets.     

Taxing Emerging Stock Markets: A Beneficial Policy? Evidence from the Stockholm Stock Exchange, 1907-1939

The question of whether financial markets should be taxed or not has been debated extensively. In this study, the gradual rise in public taxation of the Stockholm Stock Exchange during the first half of the 20th century is examined and evaluated. The empirical findings, focusing on trading volume and volatility, show that transaction taxes caused substantial crowding out of trading activity and led to lower asset prices. Hence, some support is given to the proponents of a more cautious policy of financial market taxation, especially in emerging stock markets.     

Does Real Exchange Rate Volatility Affect Sectoral Trade Flows?

This article investigates empirically the effect of real exchange rate volatility on sectoral bilateral trade flows between the United States and its top 13 trading partners. Our investigation also considers those effects on trade flows that may arise through changes in income volatility and the interaction between income and exchange rate volatilities. We provide evidence that (i) exchange rate volatility does not systematically affect sectoral trade flows, (ii) income volatility has little impact on trade flows, and (iii) the effect of the interaction term on trade flows is opposite that of exchange rate volatility, dampening its impact on trade flows.     

The effect of circuit breakers on expected volatility: Tests using implied volatilities

Following the 1987 stock market crash, trading controls or circuit breakers were implemented in financial markets to moderate extreme volatility. However, the effectiveness of circuit breakers on the operation of these markets is disputed. While some argue that circuit breakers curb the effects of overreaction in markets and restore confidence, others argue that these trading interruptions merely delay price movements to later periods or to other markets. This paper examines the effect of changes in circuit breaker rules on the market's expectation of future volatility. The results have policy implications and suggest that the circuit breaker rule changes have no effect on expected volatility.     

A structural break in the effects of Japanese foreign exchange intervention on yen/dollar exchange rate volatility

We study the impact of Japanese foreign exchange intervention on the volatility of the yen/dollar exchange rate since the early 1990’s in a GARCH framework with interventions as exogenous variables. Using daily intervention data provided by the Japanese Ministry of Finance, we show that the effect of interventions varies over time. From 1991 up to the late 1990’s, Japanese foreign exchange intervention is associated with an increase in volatility of the yen/dollar exchange rate. After the year 1997, Japanese foreign exchange intervention correlates with reductions in exchange rate volatility. This can be explained by the fact that Japanese foreign exchange intervention remained quasi unsterilized in the liquidity trap.

Changes in the socialist countries: Contents and prospects

Abstract

This paper examines volatility transmission and conditional correlations behaviour between the US and the Asian stock markets considering the effect of the Global Financial crisis. One Asian mature market and 10 emerging markets are included in the sample. To carry out the analysis, we use a multivariate asymmetric GARCH model. Results show that there exists volatility transmission between the US and the Asian markets. Moreover, it is found that, after the crisis, volatility transmission patterns have barely changed. Finally, results suggest that the lower the country‘s level of development, the lower the correlation with the USA.     

The Post‐Mao economic reform in China: A Korean view

Abstract

Previous studies that were concerned with the impact of depreciation of the ringgit on the Malaysian trade balance employed data either between Malaysia and rest of the world or between Malaysia and each of her major trading partners. Specifically, the bilateral trade balance between Malaysia and the US is shown to be insensitive to the real bilateral ringgit–dollar rate. In this article we wonder if disaggregating trade flows between Malaysia and the US by commodity could help us to discover any significant effects that the real exchange rate could have. We consider 101 industries that export from US to Malaysia and 17 industries that import from Malaysia. While majority of the industries showed short-run sensitivity to the real bilateral exchange rate, short-run effects lasted into the long run almost in half of the industries in both group.     

Real Impacts of Intra-European Exchange Rate Variability: A Case for EMU?

Intra-European exchange rate variability has significant economic costs. VAR causality tests show that higher short-run variability of exchange rates against other EU currencies was associated with higher unemployment, less employment, and lower investment for most EU member countries. Robustness tests show that this result holds up in the presence of both policy instruments that might have had an impact on exchange rate variability and cyclical variables that might have influenced labor demand. A model that incorporates the option value of waiting suggests that even short-term spikes in volatility exert a strong impact on investment and labor markets.

The Effects of Central Banks’ Rate Change Patterns on Financial Market Variables

This study examines whether different patterns of change to the benchmark interest rates of central banks are associated with their contributions to variances in the forecast errors of three financial market variables: the long-term interest rate, the foreign exchange rate, and the stock market index. On average, the central bank’s interest rate accounts for approximately 20% of the variance in each variable. We find that the total range of changes is more important than the frequency of changes. The panel regression shows that the range and frequency of policy rate changes is positively associated with the volatility of long-term interest rates but no association with the volatility of stock prices and exchange rates. These results suggest that small and frequent adjustments of policy rates are desirable for reducing the volatility of interest rates. The panel VAR represents interest rate channel is a more important than exchange rate and stock price channel.     

Deciding to Peg the Exchange Rate in Developing Countries: The Role of Private-Sector Debt

We argue that a higher share of the private sector in a country’s external debt raises the incentive to stabilize the exchange rate. We present a simple model in which exchange rate volatility does not affect agents’ welfare if all the debt is incurred by the government. Once we introduce private banks who borrow in foreign currency and lend to domestic firms, the monetary authority has an incentive to dampen the distributional consequences of exchange rate fluctuations. Our empirical results support the hypothesis that not only the level, but also the composition of foreign debt matters for exchange-rate policy.
