Privatization and entries of foreign enterprises in a differentiated industry

We investigate whether or not privatization is beneficial from the viewpoint of social welfare in a monopolistic competition model. We discuss the relationship between the welfare effects of privatization and the degree of foreign direct investment in the private sector, which is an important problem in developing countries and in transition economies such as China and Central and Eastern European countries. We find that, in the long run, privatization of a public firm is more likely to improve welfare when the country depends on foreign capital in the private sector, whereas the opposite tendency exists in the short run.     

Hospital use behaviors and associated costs in a health insurance organization, Japan

Physicians are known to play an important role in the rise of health care costs. But patients--the other side of the chain of health care systems--have been given little attention. The present study utilized the outpatient claims (in the belief that the outpatient hospital visits are mainly decided by the patients) from a health insurance organization in Japan (the Fukuoka Prefecture public service mutual aid association for government employees who serve in small cities, towns, and villages) to analyze the employee behaviors in the use of hospital care and the costs associated with these behaviors. Number of diseases diagnosed for an employee, number of claims an employee submitted for one disease, number of hospitals an employee visited, number of claims an employee had from one hospital, and the total number of claims an employee submitted were used to describe the hospital use behaviors. Results showed that some employees exhibited unusual behaviors, characterized by having an extremely large number of diseases diagnosed, visiting a large number of different hospitals, having a large number of claims, etc. Higher medical expenditures were associated with such behaviors. The findings of this study suggest that the patients' role in the rise of health care costs cannot be ignored, and cost-containment strategies targeting modification of patient behaviors in the use of hospital care may prove to be very useful.     

Japanese fiscal reform: fiscal reconstruction and fiscal policy

This paper evaluates the recent movement of Japanese fiscal reform. We first summarize fiscal policy in 1990s. Then, we investigate several relevant topics of fiscal policy such as the macroeconomic impact of government debt and the sustainability problem. We then consider dynamic properties of fiscal reconstruction process by analyzing the dynamic game among various interest groups. This paper points out that the long-run structural reform is more important than the short-run Keynesian policy in Japan.     

International environmental outsourcing

In recent years there has been a dramatic increase in the number of firms shifting stages of their production processes overseas. In this paper we investigate whether firms outsource the dirtier stages of production to minimise domestic environmental regulation costs—a process broadly consistent with the pollution haven hypothesis. We develop a theoretical model of international environmental outsourcing that focuses on the roles played by firm size and productivity, transport costs and environmental regulations. We test the model’s predictions using a firm-level dataset for Japan and do find evidence of an ‘environmental outsourcing’ effect.     

Individual preferences on trade liberalization: evidence from a Japanese household survey

This paper studies an individual’s preference on trade liberalization using a Japanese household survey, the Keio Household Panel Survey. As a result, we show that preferences toward trade liberalization are affected by economic factors (income, gender, family, asset, and job status) as well as noneconomic factors (noncognitive factors and behaviroal biases). We find that male, educated, and people with smaller family prefer trade liberalization. Furthermore, people who prefer liberty to equality and have less local patriotism, tend to be positive to trade liberalization.

     

Should Firms Employ Personalized Pricing?

This paper theoretically considers a duopoly model in which all firms do not always employ personalized pricing. Our model incorporates the fact that firms engage in marginal cost‐reducing activities after they decide whether to employ personalized pricing. When the ex ante cost difference between the firms is large, the less‐efficient firm does not employ personalized pricing even when the fixed cost to do so is zero. This is because employing personalized pricing induces the rival firm to engage more in reducing its costs, which is more likely to harm the less‐efficient firm.
