This paper documents the prevalence, duration, and marital outcomes of cohabiting unions in Japan. It then examines the correlates of cohabitation experiences and describes differences in the family formation trajectories of women who have and have not cohabited. Cohabitation has increased...

The leading economic explanation for tipping -that is, explanation why the practice is socially beneficial, not why individuals leave tips even though it is not narrowly advantageous to them- is that it confers an incentive to provide personal services. This fits many instances in which tipping...

This study augments a second-generation Schumpeterian growth model to employ human capital explicitly. We clarify the general-equilibrium interactions of subsidy policies to R&D and human capital accumulation in a unified framework. Despite a standard intuition that subsidizing these...

We consider the problem of fairly allocating one indivisible object when monetary transfers are possible, and examine the existence of Bayesian incentive compatible mechanisms to solve the problem. We propose a mechanism that satisfies envy-freeness, budget balancedness, and Bayesian incentive...

We examine whether cooperation in R&D leads to product market collusion. Suppose that firms engage in a stochastic R&D race while maintaining the collusive equilibrium in a repeated-game framework. Innovation under competitive R&D creates inter-firm asymmetries, which destabilizes the collusive...

Using a simple product differentiation model with elastic demands, we investigate the relationship between differentiation strategies and vertical relations. Depending on the competitive structure in the upstream market, three differentiation patterns (maximum, minimum and partial...

We examine generational differences in risk-taking behavior by means of a laboratory experiment with monetary incentives. We estimate the parameterized models in the framework of cumulative prospect theory and examine the risk aversion, probability weightings and reference point adoption of...

This paper considers the object allocation problem introduced by Shapley and Scarf (1974). We study secure implementation (Saijo, Sjostrom, and Yamato, 2007), that is, double implementation in dominant strategy and Nash equilibria. We prove that (i) an individually rational solution is securely...

The goal of this paper is to detect the degree to which court decisions control the stringency of employment protection and to investigate how such judicial discretion affects labor market performance. However, identification difficulty arises because court decisions are volatile against...

This study examines the effect of yardstick regulation in Japan's gas distribution sector, especially focusing on its effect of reducing the adverse selection problem. The Japanese government has regulated the price of city gas supplies by a combination of fixed-price regulation and ex-ante...
