Regional Developments by Making Intellectual Property Public Domain

In this paper, the Japanese methods of regional developments with media contents are being analyzed. Taking Hokkaido or Sakaimitato as examples, the effects on the tourism with media contents will be explained in detail. Then, as a new idea, the concept of local consumed intellectual property will be proposed. Finally, the measures of solution of copyright which is difficult to deal with when using media contents would be discussed by including legislations.     

An optimal monetary policy in an aggregate neoclassical model of economic growth

This paper shows that the usual Ramsey-Cass-Koopmans optimal-growth theory is applicable to decentralized monetary economies and illustrates, with a simple model, how optimal growth can be achieved via a simple monetary policy. Securities and the endogeneity aspect of the money supply are explicitly introduced. This paper shows that the steady state under optimal growth is a saddle point, that the dynamic behavior of the capital-labor ratio and real per capita consumption is identical to that found in the usual literature in which money is not introduced, and that the optimal monetary policy is “counter-cyclical.”     

Capital Taxation, Tobin's q and Overlapping Generations

This study examines the effect of capital taxation on the long-term equilibrium in an intertemporal model, incorporating overlapping generations of the Blanchard–Weil type and value-maximizing firms with adjustment costs in investment. I demonstrate that an increase in capital taxation raises the steady-state expected lifetime utility of an agent born after the tax increase, provided the intergenerational redistribution effect achieved through lowering the rate of return is greater than that achieved through the tax revenue effect owing to the reduced capital–labour ratio, and that an increased ITC rate would not necessarily raise the steady-state lifetime utility of all agents.

Wage Inequality and Human Capital Formation under Migration Possibilities

I examine the problem in the relationship between wage inequality and human capital formation under migration possibilities. Unlike previous analyses, I incorporate the education market and the education price into the analysis, and assume that workers bear the pecuniary cost for receiving education. Given such an assumption, migration possibilities do not necessarily increase education demand since the larger demand for education raises the education price and lowers the net return on education. By modelling an economy where workers in the home country (the labour‐sending country) comprise skilled and unskilled workers and they can migrate to the foreign country (the labour‐receiving country), I show that brain gain and brain drain occur simultaneously in the home country. In particular, if wage inequality is larger in the foreign country than in the home country, skilled workers experience brain gain and unskilled workers experience brain drain in the home country. On the other hand, if wage inequality is sufficiently larger in the home country, brain drain occurs in skilled workers and brain gain in unskilled workers.     

Incentive efficient risk sharing in a settlement mechanism

The purpose of this paper is to address a question concerning risk management in continuing, multi-party, contractual, clearing and settlement arrangements through which large-value payments are typically made. We are particularly interested in the issues of incentive compatibility when a third party possesses a private information concerning the riskiness of transfers being made. If a third party possesses private information that would be of value in determining how best to settle a payment, how does the exposure of that party to the settlement risk affect the quality of information that the party chooses to provide? In this paper, we address this question by analyzing a specific class of parametric environments of a schematic, formal, model of a settlement arrangement or a payment network.     

Taxation in an Overlapping Generations Model with Human Capital

We examine the impact of flat-rate taxes on intergenerational equity in an overlapping generations model of a small open economy, assuming the intergenerational externality of human capital accumulation. The externality may cause the difference between the growth rates in private human capital and in average human capital of the economy. If the externality is sufficiently small, the introduction of an interest income tax will benefit all future generations. In contrast, if it is sufficiently great, the introduction of a wage tax could harm all generations by raising financial asset holdings and thereby reducing consumption.     

Perceptions of products made in Japan versus those made in the United States among Japanese and American executives: A longitudinal perspective

This research reports on a longitudinal survey approach in which American and Japanese executives were queried regarding their perceptions of products made in the United States and Japan over a period of 15 years. Three surveys were conducted by mail in the United States using home country executives in 1977, 1991 and 1992. One survey was conducted in Japan in 1992 using Japanese executives and is compared to the findings of Nagashima (1977). Results show that over the past 15 years, the image of American goods has been declining both in the United States and Japan, whereas that of Japanese goods has been improving. These results offer an alternative product image/attribute-based perspective as an explanation of the United States trade deficit with Japan. Over the past year, survey results also reveal that the image of Japanese goods in the United States has suffered. This finding suggests that the image of a country's products is changeable, surprisingly even in a short period of time.     

日本:形势走低但不会长久

由于全球经济自2004年开始保持强劲增长,2005年日本PC机和手机市场形势要好于预期。由于日本出口业务很多,因此全球经济对日本经济影响很大。2006年,据东京的研究机构Digital Ga- rage预计,日本经济会出现不景气。这同时也反映出以下几点:原油价格上涨之后亚洲经济的总体情况、PC机在发达国
