Using a simple overlapping generations model, this note shows that an improvement in the efficiency of human capital investment decreases the net income of the young household while increasing that of the old. Without compensating redistribution, it deteriorates lifetime utilities of all...

I introduce uncertainty into the model of strategic cost-reducing R and D investments and reexamine welfare implications. I discuss two models. In one model an increase in expenditure decreases production costs when R\&D succeeds, and in the other model it increases probability of success. I...

We investigate the equilibrium location pattern and welfare implication in delivered pricing model (or spatial price discrimination model) with a linear city. First, we extend a delivered pricing duopoly with Bertrand competition of Hamilton et al. (1989) to an n-firm model and explicitly solve...

We apply a spatial model that includes both circular-city and linear-city models as special cases to the analysis of location-quantity model in mixed oligopoly. We find that the equilibrium pattern continuously moves from that of the circular-city to that of the linear-city and that the...

This paper investigates a location-quantity model in a circular city. Pal (1998) investigates a duopoly model and finds that an equidistant location pattern appears in equilibrium. Matsushima (2001a) investigates an n-firm oligopoly model and shows that, if the number of firms is even, another...
