It covers three different contexts of social welfare evaluation, namely, social welfare evaluation within a generation, intergenerational social welfare evaluation involving infinitely many generations, and intergenerational social welfare evaluation with variable population sizes of generations.

This book investigates the relationship between environmental degradation and income, focusing on carbon dioxide (CO2) emissions from around the world, to explore the possibility of sustainable development under global warming.

Conventional wisdom dictates that a fiscal policy should be counter-cyclical. In particular, by incorporating the political effort behavior of private agents into a weak government model, we explore how income fluctuations affect the optimal budget deficits in a political economy.

The authors' empirical results suggest that utilizing soft information allows banks to attain a more precise lending decision.The Financial Services Agency in Japan introduced an action program in 2003 that requires regional banks to shift from transaction banking to relationship lending.

¿This book provides an updated overview of the recent progress in the theoretical study of third-degree price discrimination. It is a marketing tactic and is said to be present if the unit price is different across different groups of buyers. Its welfare evaluation is often difficult because it entails two countervailing effects: on one hand, it exploits surplus from consumers who have high willingness-to-pay, but on the other hand, it generates gains from trade from consumers who otherwise would not purchase the good. Recognizing this difficulty, we provide new insights on evaluation of third-degree price discrimination in consideration of network effects and vertical product differentiation. Our analysis is particularly useful for the industries related to information and communication technologies (ICT) because these two elements characterize them. Furthermore, we also study the welfare effects of third-degree price discrimination under imperfect competition other than monopoly.At first, it seems that it may complicate the analysis under monopoly. However, we argue that the main thrusts of analysis under monopoly carry over to the case of oligopoly. We also take into account behavioral aspects and their implications for studying third-degree price discrimination. Overall, this book is designed to provide implications for contemporary management and policy issues by advancing theoretical issues in industrial organization.
