Objectives: Recent studies suggest the need to adjust the construct of the Caregiver Reaction Assessment Scale among the family caregivers according to different social norms and differential public services. The aim of this study is to examine the reliability of the original five-subscale CRA...

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...

This paper considers a model of defensive medicine where doctors are imperfect agents of insured patients. A national insurer subsidises both curative and preventive medical care consumed by risk averse patients. We show that in such an environment, the optimal liability regime is similar to the...

This paper interprets number portability as a reduction of switching costs in a model of competition between telephone companies. We identify several cases by their cost and demand characteristics and show that social benefit of number portability are not guaranteed. Analysis using two-part...

In this study, we attempt to investigate how educational subsidy, childcare allowance, and family allowance affect economic growth and income distribution, on the basis of simulation models which incorporate intergenerational ability transmission and endogenous fertility. The simulation results...

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...
