The purpose of this article is to investigate the central government redistribution policies across local governments that affect regional agglomeration. Though full agglomeration is efficient, in many cases factor mobility is imperfect and the full agglomeration is not realized. This article analysed whether or not the central government should adjust the distribution of populations through local governments. The result is as follows: If individuals are relatively mobile, the central government can improve the aggregate income. In this case, when the private production and public sector are small, the central government should transfer from the productive regions local government to low-productive regions. 相似文献

This paper examines the diffusion process of Internet broadband access in Japan by modeling the household choice of access modes. Estimates reveal that the characteristics of users, rather than those of the access modes, play a significant role in demand substitution across the modes. Simulation exercises indicate that had optic fibers (fiber-to-the-home; FTTH) been made available to the whole country in 2005, only 10% of households would have switched to that mode. This result implies that once chosen, the household choice of access mode persists, and that indirect network effects are an important element in decisions to adopt the new technology of broadband. Finally, policy implications are discussed. 相似文献

Abstract . I present a model that demonstrates that the market mechanism is not always effective in stabilizing an open equity market. Foreign capital inflows create multiple equilibria in the equity market, which may simultaneously trigger a currency crisis as well as an equity market crash even if the equity market is well developed. 相似文献

We model a dynamic duopoly in which firms can potentially drive their rivals from the market. For some parameter values, the Cournot equilibrium outcome cannot be sustained in an infinitely repeated setting. In those cases, there is a Markov perfect equilibrium in mixed strategies in which one firm, eventually, will exit the market with probability one. Producer surplus in the maximum collusive outcome is greater under bankruptcy consideration, because the outcome that maximizes joint profits is skewed in favor of the more efficient firm. Consumer surplus and social welfare also increase in many cases, although those effects are generally ambiguous. 相似文献

We attempt to compare adjustment costs under exchange rate regimes in East Asian economies during their recovery processes. The criteria are the degree of overshooting in exchange rates, the changes in country risks, and the severity and duration of the recovery processes. Linear ranking is difficult. Managed rates with capital control worked for macroeconomic performance despite the welfare loss due to blocking capital flows. The currency board system worked well for stability, but recent experiences of Argentina and Hong Kong were deflationary. Under flexible rates, many economies that received IMF grants suffered a drastic initial downturn but later recovered vigorously. JEL Classification Numbers: F31, F32, F33. 相似文献

This study investigates the recent process of job polarization in Japan. We focus on three particular aspects: the relationship with business cycles, total hours rather than employment and age cohorts. We find that, regardless of whether the focus is employment or total hours, job polarization is concentrated in recessions and that job polarization has occurred mainly in younger-age cohorts. 相似文献

Abstract Most developed countries are seeking ways to maintain a sustainable social security system. Japan is no exception. The old-age dependency ratio in Japan is currently 35% and is expected to be 74% in 2050. Recently the Japanese government has adopted an automatic balancing mechanism, which gradually reduces the real price of the public pension through a reduction of inflation adjustments. The reduction, depending on future demographics, is a random process, so the elderly, in particular the extreme elderly, have to take the risk of receiving an inadequate public pension. The objectives of this paper are threefold. First, we review the recent trends in Japanese mortality and explain the underlying longevity issues that led to the automatic balancing mechanism. Second, by means of stochastic mortality and fertility modeling, we analyze how demographic changes will affect the future of public pensions in Japan. Third, we demonstrate, on the basis of the stochastic projections we made, how the automatic balancing mechanism will affect the financial security for people who live beyond age 100. 相似文献
