This paper examines the optimal entry policy towards oligopoly in an globalized world. In an open economy free entry is socially suboptimal, but corrective tax policy to curb entry proves insufficient unless internationally harmonized. Thus, while conferring the gains from trade, globalization...

This paper explores the relation between corporate governance mechanisms in Japan and the costs of public debt financing. Using a sample of Japanese corporate bond issues during the period 2005-2008, we find that CEO ownership is associated with higher yield spreads after controlling for firm-...

We develop a dynamic model in which a firm exercises an option to expand production with cash balance and costly external funds. While related papers explain their results only by numerical examples, we analytically prove the following results. In the presence of only a proportional cost of...

In this paper we present an axiomatic approach to characterize the optimal contracts, which we call gfair contracts,h in the general moral hazard model. The two main axioms we employ are incentive efficiency and no-envyness. The incentive efficiency requires that agents of organization select...

This paper analyzes the determinants of government debt and social security for the old in a closed-economy, overlapping-generation model. Under the probabilistic voting, the model presents (i) an intergenerational link of resource allocation via debt and social security; (ii) multiple political...

This paper analyzes tariff competition by investigating the strategic interactions among firms that are highly mobile across national boundaries. Although high transport costs yield a geographic dispersion of the industry, sufficiently low transport costs result in a core-periphery location...

In this paper, we develop an endogenous growth model with two coun- tries in which the international trade of differentiated goods requires dif- ferent trade costs and equilibrium wages in the two countries. If the labor productivity in one country's agricultural sector is higher than that of...

With the data of 831 Japanese water utilities from 1999 to 2008, we used the stochastic cost frontier analysis with a true fixed-effect model in order to estimate the cost efficiency and scale economies. We found that cost inefficiency was approximately 37%. The economies of water delivery...

This paper presents a welfare analysis of free entry equilibrium in dynamic general equilibrium environments with oligopolistic competition. First, we show that a marginal decrease in the number of firms at the free entry equilibrium improves social welfare. Second, we show that if a government...
