Exchange Rate Pass‐through and Currency Invoicing: Implications for Monetary Integration in East Asia

Exporter's price‐setting behaviour and currency invoicing play a key role in the literature on the new open‐economy macroeconomics. This paper estimates exchange rate pass‐through coefficients for the exports of four ASEAN countries: Indonesia, Malaysia, the Philippines and Thailand. In addition, previous estimates of pass‐through as well as invoicing behaviour in East Asia are discussed in the context of regional integration. The new pass‐through coefficients are estimated under two alternate specifications for up to 34 goods for each of the four ASEAN countries destined for up to 13 major markets. The results suggest: (a) little pass‐through is occurring in Southeast Asia and (b) this lack of pass‐through is more likely attributable to the fact that they are small countries in a relatively integrated market, rather than evidence of pricing to market. The implications for regional monetary integration of this apparently low degree of pass‐through are detailed.     

The futures premium and rice market efficiency in prewar Japan

This article studies the interrelation between spot and futures prices in the two major rice markets in prewar Japan from the perspective of market efficiency. Applying a non‐Bayesian time‐varying model approach to the fundamental equation for spot returns and the futures premium, we detect when efficiency reductions in the two major rice markets occurred. We also examine how government interventions affected the rice markets in Japan, which colonized Taiwan and Korea before the Second World War, and argue that the function of rice futures markets crucially depended on the differences in the structure of rice spot markets. Initially the increased volume of imported rice of a different variety from domestic rice disrupted the rice futures markets. Then, government intervention in the rice futures markets failed to improve the disruption. Changes in colonial rice cropping successfully mitigated the disruption, and colonial rice was promoted in order to unify the different varieties of inland and colonial rice.     

Currency Invoicing in Japanese Exports to East Asia: Implications for Yen Internationalization

The present paper examines currency invoicing in Japanese exports to East Asia by applying the pricing-to-market (PTM) theory. The notable aims of the present paper are to: (i) use a number of sample commodities obtained from the data on monthly series of exports based on the nine-digit Harmonized System; and (ii) examine currency invoicing practices of Japanese exporters by making a distinction between the long-run and short-run PTM under the framework of the error-correction model. Contrary to the results of previous reports, our study shows that Japanese exporters of electric machinery tend to stabilize US Dollar (USD)-denominated export prices in the short run in East Asian markets, implying that electric machinery products tend to be invoiced in USD in exports to East Asia. Given the USD-invoicing practices by Japanese electric machinery exporters, it is hard to expect the further use of the Yen in trade transactions because the electric machinery industry plays a major role in facilitating trade and investment between Japan and East Asia.     

Should Chinese Renminbi be Blamed for Its Trade Surplus? A Structural VAR Approach

During the recent years, the Renminbi (RMB) exchange rate issue has been at the centre of ongoing debate over the source of global current account imbalance, especially with the United States. The objective of this study is to contribute to the current discussion by providing some new evidence on China’s exchange rate policy and the impacts of RMB devaluation/revaluation on China’s trade balance using a structural vector autoregression (VAR) approach. The results indicate that the dynamic effect of exchange rate on China’s trade balance is still very limited and China’s balance of trade is mainly determined by the world demand and its trade performance, with the latter being a result of its successfully maintained comparative advantage.     

Empirical Study of Nikkei 225 Options with the Markov Switching GARCH Model

This paper investigates the pricing of Nikkei 225 Options using the Markov Switching GARCH (MSGARCH) model, and examines its practical usefulness in option markets. We assume that investors are risk-neutral and then compute option prices by using Monte Carlo simulation. The results reveal that, for call options, the MSGARCH model with Student’s t-distribution gives more accurate pricing results than GARCH models and the Black–Scholes model. However, this model does not have good performance for put options.     

Industry‐specific Real Effective Exchange Rates and Export Price Competitiveness: The Cases of Japan,China, and Korea

This paper constructs a new dataset of the industry‐specific real effective exchange rate, based on the producer price indices, for Japan, China, and Korea on a monthly basis from January 2001 to February 2013 in order to provide a better indicator for export price competitiveness. By conducting simulation analysis, we found that Korean electrical machinery firms substantially improved their cost competitiveness by lowering their production costs during the Korean won appreciation period, while Japanese firms' large plant investment caused by management misjudgments led to excessive production capacity, which resulted in the deterioration of Japanese export competitiveness. A structural vector autoregression analysis also reveals that industry differences of cost competitiveness as well as nominal exchange rate changes have significant impact on export performances of Japan and Korea.     

Whither A Currency Union in Greater China?

The paper attempts to evaluate the prospect of creating a currency union in the “Greater China” economic area. Despite of the political deadlock and military confrontation in the Taiwan Strait, the Greater China area has experienced rapid and spontaneous regional integration in the past decades as a result of increasingly cross-border trade, foreign direct investment (FDI), technology contracts, and other arrangements in accordance with changes in comparative advantage and industrial upgrading in these economies. In this study, we focus on the symmetry in shocks that is perceived as one of the major preconditions of a currency union. In contrast to the previous studies, we investigate the time-varying correlation of supply, REER and monetary shocks by using the Kalman filter technique to assess the dynamic changes in structural similarity and convergence among the Greater China economies. We also examine the costs of forming a currency union in the area due to the loss of monetary autonomy in each economy. Our results suggest that there is a rising structural symmetry between the Greater China economies, and this area has become increasingly a better candidate for a monetary union.

Is a monetary union feasible for East Asia?

The empirical suitability of the East Asian economies for potential monetary integration is assessed. The structural vector autoregression (VAR) method is employed to identify the underlying shocks using a three-variable VAR model across the East Asian economies. The estimates of the EEC are used as a benchmark to compare the size of the underlying shocks and the speed of adjustment to shocks in both regions to determine the feasibility of forming an optimum currency area (OCA) in East Asia. The empirical results do not display strong support for forming an OCA in the East Asian region. The results do imply, however, that some small subregions are potential candidates for OCAs, since their disturbances are correlated and small and these economies adjust rapidly to shocks.     

On the comparison of alternative specifications for money demand: The case of extremely low interest rate regimes in Japan

Using Japanese money market data, this paper compares the predictive ability of the log–log specification with infinite elasticity at a zero interest rate and the semilog specification with a one time switch from moderate to relatively high semielasticity at annual interest rates less than 0.5%. We find that the latter specification dominates the former in terms of predictive ability for the extremely low interest rate regime (the period between 1999 and 2006) because under the former the semielasticity is excessively sensitive to slight changes in interest rates. We find that interest rate semielasticity has remained stable at a high level since the mid-1990s.     

Recalculating the agricultural labor force in China

In this study, we use a hypothetical method to recalculate the agricultural labor force based on statistical data on the labor force in China. We confirm the revised agricultural labor force data by estimating the agricultural production function. Through comparing the marginal labor productivity with the subsistence level of wages in the agricultural sector, we find that the overstated figures of agricultural labor force not only result in the underestimation of agricultural labor productivity but also are misleading by indicating that China reaches the Lewis turning point later than in actuality. The process of labor transfer in China, a large part of which is through rural migrant workers, has been much faster than expected.
