Monetary and Fiscal Policy to Escape from a Deflationary Trap

This paper provides a theoretical overview of monetary and fiscal policy with the potential to engineer an exit from a deflationary trap, which we define here as sustained deflation in the presence of zero interest rates. We find that the required policy steps are an interest rate hike, a commitment to future currency growth, and a money-financed tax cut. The amount of tax cut required is equal to the increase in the central bank's payments to the treasury resulting from the higher inflation rate (nominal interest rate), while fiscal policymakers must maintain fiscal discipline by stabilizing government debt and the primary balance. There will be a temporary fall in output when prices are sticky, but this is the price that must be paid to conquer deflation. The current commitment to quantitative easing is based on the assumption that the natural interest rate has temporarily declined. If the economy is in a deflationary trap, however, the continuation of zero interest rates reinforces deflationary expectations and may make it perpetually impossible to eliminate deflation. Even under conditions in which the natural rate of interest seems to be positive, if deflation persists, it is probably wise to consider a policy approach that assumes deflationary trap conditions. With this in mind, we believe the conditions required for abandoning the current policy regime should include, in addition to consistently positive growth in the consumer price index (CPI), a consideration of the trend in real GDP.

Issues in Japanese Health Policy and Medical Expenditure

This paper first discusses the past patterns of the national medical care expenditure and its future path. About 30 percent of the past growth was due to population aging and the remaining 70 percent was due to technological change. The medical expenditure is expected to increase by about 20 percent in 20 years due to population aging. The latter half of the paper focuses on a reform plan of the health insurance for the elderly and presents some policy recommendations. One of the most serious problems in the health care market is that virtually no agents evaluate the quality of medical services or help improve it. It has not been clarified whether the rising medical costs are the result of waste or of necessity. Reform should attempt to make insurers play a more active role in the health care market as informed agents of patients. Dramatic outsourcing of the health insurance business to the private sector should be promoted.health insurance, medical cost, managed care

"The Fiscal Investment and Loan Program in Transition"

This paper discusses the adequacy of the activities of the Fiscal Investment Loan Program agencies after the fundamental reform in April 2001, which disconnected postal savings and public pension reserves from the FILP. It is found that many ideas of justifying the government interventions to the financial sector have now lost their relevancy. The activity of government financial intermediaries should be streamlined. Among infrastructure construction projects, the most serious part of welfare loss lies on national motorway construction, which is estimated to be about 14.5 trillion yen of welfare loss.

Policy Options for Financing the Future Health and Long-Term Care Costs in Japan

As the Japanese population structure changes, health care and long-term care costs will steadily increase. The current style of financing (pay-as-you-go) will create a large increase in future burden of these costs. This paper studies an alternative policy that prefunds the social insurance benefits for the elderly. During a transition process, the proposed scheme maintains a higher contribution rate in order to accumulate sufficient funds. Under our baseline scenario, the sum of the contribution rates toward health insurance and long-term care insurance increases from 5.06 percent of earnings to 12.41 percent of the same. The rate of increase in overall burdens, including taxes and subsidies, is 63 percent. Our sensitivity analysis has shown that the quantitative implications of the increase in total burdens depend on social cost scenarios, the labor force, and the interest rate. However, labor force scenarios do not have a considerable impact on the rate of burden. As against this, the setting of social costs has a significant impact on the same. Even under the most optimistic scenario, the rate of increase in total burden is 34 percent. Even though we cannot predict the exact amount of the necessary contribution rate that is capable enough to transfer the funded system, what we are sure of is that a significant increase in the contribution rate is inevitable.

"International and Intergenerational Aspects of Capital Income Taxation in an Endogenously Growing World Economy"

This paper discusses how capital income taxation affects economic growth and welfare in an endogenously growing world economy with perfect capital mobility and worldwide externalities. Worldwide ex-ternalities provide a mechanism for equalizing national growth rates even with different capital income tax rates. The welfare of future generations is more influenced by a change in the growth rate than by the international spillover effect which has been the primary concern of the previous studies. Moreover, our model finds intergenerational conflicts arising from the change in the growth rate caused by a change in the source tax rate of the foreign country.

On the Consumption Insurance Effects of Long-term Care Insurance in Japan: Evidence from Micro-level Household Data

Using micro-level household data in the 2001 Comprehensive Survey of the Living Conditions of the People on Health and Welfare compiled by the Japanese Ministry of Health, Labor and Welfare, this paper examines how having a household member in need of long-term nursing care can result in welfare losses measured in terms of consumption. In so doing, this study evaluates the role of the public long-term care insurance scheme implemented in Japan in April 2000. The results indicate that when households include a disabled family member, household consumption net of long-term care costs do not decrease as much as before the introduction of long-term care insurance. Further, when compared with the surveys conducted in 1998, theadverse effects on consumption net of long-term care costs have become much weaker. These findings suggest that the introduction of social insurance in 2000 helped Japanese households to reduce the welfare losses associated with a disabled family member.social insurance, consumption insurance, long-term care insurance
