This book provides a comprehensive, theory-based analysis of current issues in population economics. It addresses the most important problems caused by demographic changes using the popular overlapping generations growth model by Samuelson and Diamond. Taking into account families' fertility decisions, it examines not only the demographic changes due to longer life expectancy but also the effects of social security policy on demography and labor supply/individual retirement behaviors. Conducting all analyses in a dynamic general equilibrium setting, the book offers a valuable theoretical reference guide in the field of population economics.

An important feature of this book is its analysis of various contemporary issues in applied economics, distinguished by advanced theoretical research and empirical analysis focusing on Japan and Korea. The book consists of four parts, the first of which investigates economic growth and welfare, using tools of applied analysis. In Part II, it examines inequality, redistribution, and intergenerational transfers, mainly on an empirical basis. In turn, Part III explores public policy and political economics, while Part IV addresses resource and environmental economics on the basis of data from Japan and Korea. In addition to offering valuable insights, this collection of papers commemorates the 10th anniversary of academic exchange between the Japan Association for Applied Economics (JAAE) and the Korean Association for Applied Economics (KAAE).
