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.     

Evaluation of Asian Income Distribution and Poverty Ratios Using Worldwide Income Distribution

This paper aims to estimate worldwide income distribution for multiple years, and then to use this data in evaluating income distribution for particular countries or areas. Based on previous contributions to estimate the worldwide distribution for a particular year, worldwide income distribution was estimated by using per capita GDP, purchasing power parities of the International Comparison Programme, and income distribution data for various countries. Results for four years show that Gini coefficients exceeded 0.5 and were relatively stable from 1962 to 1985. Income distribution for the Asian area is compared to worldwide income distribution. A Relative Advance Index is proposed to measure the position of a country's particular income distribution in relation to worldwide income distribution. The Index shows that Asian income distribution has shifted toward higher income as compared to worldwide income. The paper also suggests that worldwide income distribution can be used to determine the poverty level cutoff point.     

Globalisation,multinationals and productivity in Japan’s lost decade

This paper studies the process of plant exit and productivity growth in Japan during the ‘lost decade’. A productivity decomposition shows the low rate of productivity growth at the aggregate level to be due to slow within plant productivity growth and a small contribution from the entry and exit components. We find the causes of plant exit to be similar to results in other country contexts except we find no effect from import competition. Our results suggest that the low productivity growth is attributable to high entry barriers and little to the shutting of productive plants by MNEs.     

How Does FDI Affect Productivity at Home?: Evidence from a Plant-Level Analysis

This study investigates the effect of foreign direct investments (FDI) on home productivity using plant-level data rather than firm-level data. Our results are consistent with the theoretical predictions. Horizontal FDI (HFDI) does not have a significantly positive effect on home productivity in plants that have the same activities abroad. In contrast, vertical FDI (VFDI) significantly enhances productivity in plants with an input–output relationship with activities relocated abroad. Furthermore, focusing on FDI in East Asia, the productivity improvements at home through VFDI are even greater, which might be caused by significant differences in factor prices between Japan and host countries.     

von Neumann–Morgenstern stable sets of income tax rates in public good economies

This paper studies the von Neumann–Morgenstern stable sets in a public good economy, where any allocation is achieved through a proportional income tax system. The outcome of the economy is defined to be a set of tax rates. We show that whenever the core as the set of tax rates is nonempty, it is a unique stable set. When the core is empty, the set of tax rates is a stable set if and only if the set is a singleton consisting of a tax rate satisfying a certain condition. We show the existence of such stable sets.

He is also grateful to Youngsub Chun, Takuya Masuzawa and Shigeo Muto for their helpful comments.     

Current accounts of Japanese airports

The paper examines the current account of 41 major airports. When we exclude depreciation costs, only seven airports are profitable. When depreciation is excluded, only three airports are making profits. Airports managed by local governments are very difficult to sustain financially without subsidies. Airports with more than 5.2 million passengers are profitable when depreciation is taken into account, however most local airports have fewer than 2.5 million passengers. When depreciation costs are excluded, airports need at least 2.7 million passengers to be viable.     

Closure within multi-plant firms: evidence from Japan

In the literature there is substantial evidence that a plant is more likely to be closed down if it is owned by a firm with other plants or is owned by a multinational enterprise (MNE). But does ownership or multi-plant status matter for which plants are closed? Using Japanese data we study plant closure by multi-plant MNEs and non-MNEs. We show that both organisational forms raise the probability of plant exit and that plants that are relatively small and capital unintensive relative to the rest of the firm are significantly more likely to exit.
