Implications of the minimum access rice import on supply and demand balance of rice in Japan

The recent development of rice policies in Japan are summarized. The impact of the minimum access (MA) import on the supply and demand balance of rice, and the rice diversion areas in the future is also predicted.     

Modeling international trade flows and market shares for agricultural commodities: a modified Armington procedure for rice

The Armington procedure (AP) has become increasingly popular in agricultural trade analyses. However, some arguments have arisen concerning the relevance of using the procedure for such analyses. This study examines the assumptions commonly made when using the Armington procedure and suggests modifications for agricultural trade analyses. Results from models utilizing rice-trade data suggest that the assumptions of the single constant elasticity, in particular, may not be appropriate for analyzing agricultural trade. These results also suggest that, with proper modifications, the AP can be applied to agricultural trade. Further, results of a modified Armington procedure indicate that trade in rice exports is highly competitive and that changes in market shares of individual exporters are not independent of changes in budget expenditure allocated to imports.     

Cointegration and spatial price transmission among wheat and wheat-flour markets in Afghanistan

This article examines cointegration and spatial price transmission among Afghan wheat and flour markets as well as their linkages with those of supplier countries and global markets. Unit root tests, consistent momentum threshold autoregressive (M-TAR) models and vector error correction models (asymmetric and symmetric) are employed to achieve research objectives. The results suggest that provincial wheat and flour markets may have a long-run relationship with principal market of Kabul. Afghan wheat and flour markets may also be cointegrated with their respective global, Kazakh and Pakistani markets. While provincial wheat markets might adjust to divergence from their long-run equilibrium with Kabul wheat market, some of the provincial flour markets may not respond to deviation from their long-run equilibrium with Kabul flour market. The speed of adjustment towards the long-run Afghan–Pakistani and Afghan–Kazakh equilibrium may be faster for Afghan flour than wheat markets. The equilibrium adjustment coefficients are generally small and market imperfections may exist, however. A shock in Kabul wheat and flour markets may have long-lasting effect on the respective provincial markets whereas a shock in global wheat and Pakistani, and Kazakh wheat and flour markets might have transitory effect on the corresponding Afghan markets.     

Developing E-Business Dynamic Capabilities: An Analysis of E-Commerce Innovation from I-, M-, to U-Commerce

This study uses an electronic commerce (E-commerce) innovation model to analyze the differences in technological knowledge, business model, and dynamic capability aspects used in Internet-enabled commerce (I-commerce) versus mobile commerce (M-commerce) versus ubiquitous commerce (U-commerce). The results indicate that the innovation from I-commerce to M-commerce is radical, leading to drastic changes in the business model. However, from M-commerce to U-commerce, disruptive changes occur in both technological and business model dimensions. A set of critical dynamic capabilities for each innovation is identified. These results provide great insight for practitioners and scholars for enhancing their understanding of E-commerce innovation, and provide guidelines to help practitioners adapt from one type of innovation to another.     

The Wage Rate and the Worker's Productivity: the Case of the Japanese Chemical Industry

The purpose of this paper is to analyze the relationship between the wage rate and the productivity of the blue-collar worker in Japan. In this paper, micro data from a factory of chemical industry in Japan is used for our empirical study. Our empirical results indicate that, if the index of the labor productivity is an appropriate index of the labor productivity, the labor productivity plays a crucial role in the determination of the wage rate in a particular Japanese chemical factory of the 1960s.     

An econometric analysis of rice consumption in the People's Republic of China

Rice is the most important staple food in the People's Republic of China (PRO. In many Asian countries rice appears to have become an inferior good, with income increases leading to declines in per capita consumption as other food products are substituted for rice. In this study, human rice consumption is analyzed with a model that allows income elasticities to vary with income levels. An additional equation accounting for rice disappearance as seed, livestock feed, industrial uses and exports is also estimated. The results of the analysis indicate that rice has become an inferior good in China and per capita consumption is likely to decline in the future. Population growth and the growing use of rice for other purposes means that total rice disappearance will continue to increase although at a rate that is slower than has historically been the case. The predicted changes in rice consumption will create pressures to adjust production and trade patterns for rice as well as other agricultural products.     

ESTIMATES OF INTANGIBLE INVESTMENT BY INDUSTRY AND PRODUCTIVITY GROWTH IN JAPAN

In estimating intangible investment in Japan at the industry level, we find a high intangible investment/gross value added ratio in the information technology (IT) sector and negative growth rates in intangible capital in 13 industries over the decade from 2000. When we examine the impacts of intangible investment on total factor productivity growth, we find a significant and positive effect on total factor productivity growth in the market economy. In a revised estimation that considers intertemporal knowledge spillovers, the estimated rate of return on intangibles in the IT sector is quite high after the IT revolution. The results imply that intangible assets have been underinvested in the IT sector.
