In this paper, we investigate what people in Japan consider when deciding to take the influenza vaccination. We develop an economic model to explain the mechanism by which people decide to take the influenza vaccination. Using our model and the data obtained from a large-scale survey we...

This paper analyzes market diffusion in the presence of oligopolistic interaction among firms. Market demand is positively related to past market size because of consumer learning, networks, and bandwagon effects. Firms enter the market freely in each period with fixed costs and compete in...

This paper's objective is to design a laboratory experiment to explore the effect of Knightian uncertainty on a subject's search behavior in a finite sequential search model. Our finding is that the average search duration is shorter when there is Knightian uncertainty in the sense that the true...

This paper's objectives are to design laboratory experiments of finite and infinite sequen- tial collective search models and to test some implications obtained in the model of Albrecht, Anderson and Vroman (2010) (the AAV model). We find that, compared with single-agent search, the average...

This paper estimates matching functions to measure search frictions in the Japanese labor market and presents determinants of search duration to explain the effect of unemployment benefits on a job seekerfs behavior. We employ administrative microdata that track the job search process of...

From data collected by questionnaire survey of three communes in the Kandal province of Cambodia, where public water supply remains inaccessible, this study estimates the demand function for drinking water and finds that the price elasticity is between -0.26 and -0.29. Based on this, and given...

We introduce into a Schumpeterian growth model an inventive step, which is a minimum innovation size required for patents, and thus a patentability requirement. We show that in order to satisfy an inventive step requirement, each R&D firm targets only industries in which the incumbentfs...

This study presents a two-period overlapping-generations model featuring en- dogenous growth and intergenerational conflict over fiscal policy. In particular, we characterize a Markov-perfect political equilibrium of the voting game between gen- erations, and show the following results. First,...

This paper develops a two-period overlapping-generations model featuring en- dogenous growth and intergenerational conflict over fiscal policy. In particular, the paper characterizes a Markov-perfect political equilibrium of the voting game be- tween generations, and shows the following results....

This study presents an overlapping generations model to capture the nature of the competition between generations regarding two redistribution policies, public education and public pensions. In addition, we investigate the effects of population aging on these policies and economic growth from a...
