We study the role of liability rules in the case of nuclear accidents by the Tokyo Electric Power Company (TEPCO), such as the accident after the East Kanto Earthquake in Japan. We re-examine the claim that the absolute or unlimited liability is the best under actual situations. For example,...

We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on the assumption that the population is finite. For infinite populations, there exist non-dictatorial social welfare functions...

We present a framework to examine how a standard evolves when a standard consortium or a firm (incumbent) innovates either to improve the standard or to strengthen installed base which increases switching cost. Both investments make it more difficult for another firm (entrant) to introduce a...

Background: In duration analysis, we find situations where covariates are simultaneously determined along with the duration variable. Moreover, although the models based on a hazard rate do not explicitly assume heterogeneity, in applied econometrics, the possibility of omitted variables is...

Personal lifestyle choices such as leisure-time physical activity are major determinants of both the health and happiness of individuals. However, price discrimination exists between municipalities at almost public sports facilities. An economic intervention to change the cost of using public...

By using panel data, this study examines the effect of unemployment on various types of individual health-related behavior, namely physical exercise, dietary habits, smoking, drinking, and sleep duration among Japanese men aged 20 ?40 years. The results indicate that the effect of unemployment...

This paper examines how expected attachment to the labor market and expected tenure at a specific firm affect training participation. The results, based on cross-sectional data from Japan, indicate that expected attachment to the labor market affects participation in both employer- and...

In an infinite-horizon setting, Ferejohn and Page showed that any social welfare function satisfying Arrow’s axioms and stationarity must be a dictatorship of the first generation. Packel strengthened this result by proving that no collective choice rule generating complete social preferences...
