Population aging and industry structure:Service sector growth, elderly employment, and pension reform

I analyzed a dynamic relationship between population aging and industry structure, and answered to the question of how we should reform the related public policies, theoretically and empirically. At this time, I have got three main research outcomes. First, the Petty-Clark’s law can be explained in the context of population aging. Second, a proper subsidy policy for informal care service industry can be Pareto-improving even in a case that healthy life expectancy at birth increases. Third, population aging causes drastic changes in the scale of income redistribution that is politically sustainable if individuals have altruism towards persons that have the same attribute as them, e.g., if individuals share good feelings among the same generation or the same social class.
