This study constructs a variety expansion growth model that integrates basic research to analytically examine its effects on household welfare. In our approach, the research sector consists of applied and basic research components. The former creates blueprints and expands the variety of goods...

This study examines growth cycles in a simple discrete-time two-country model of in- novation. In this setting, we find that there are two key driving forces that give rise to cycles. They are perfect international capital mobility and perfect international knowledge spillovers. In addition,...

By using the panel data of 59 semiconductor companies in 2001-2013 this study investigates the characteristics of financial condition of each product segment and explores the effective product line policy in semiconductor industry. Semiconductor is well-known as one of the fundamental products...

This paper develops an overlapping-generations model including wage inequality within a generation and intra- and intergenerational resource reallocation via social security. Based on the concept of a stationary Markov perfect equilibrium, the paper focuses on the feedback mechanism between...

The hypotheses of non-addiction, myopia and rational addiction are tested using annual, quarterly and monthly data. Changes in the prices of Japanese cigarettes can be viewed as natural experiments from the point of view of consumer behavior, because the Japanese government controls cigarette...

This study develops a new model-free benchmark of implied volatility for the Japanese stock market similar in construction to the new VIX based on the S&P 500 index. It also examines the stochastic dynamics of the implied volatility index and its relationship with realized volatility in both...

This paper characterizes a stationary Markov perfect political equilibrium where agents vote over income taxation that distorts their educational investment. Agents become rich or poor through educational investment, and the poor have a second chance at success. The results show the following...

This paper constructs a model of anticompetitive exclusive dealing in the presence of multiple entrants. Unlike a single-entrant model in the extant literature, an entrant competes not only with the incumbent to deal with buyers but also with other entrants. The competition among entrants then...
