dc.description.abstractThe dissertation has three main chapters on product quality innovation. First, we compare innovation effort and social welfare between monopoly, duopoly, and the social planner in a dynamic model with quality dependent on a continuous know-how stock. The technology frontier--the largest reachable know-how socks--does not always positively depend on competitiveness, i.e. a duopoly may technologically surpass the social planner. However, social welfare is always positively tied to competitiveness. Second, with a general equilibrium model, we derive a relative price function expressing productivity and quality effects, and develop a method for inferring relative quality changes. An application to services versus goods of the US from 1946-2006 provides evidence on aggregate quality changes and suggests us to incorporate quality variations when explaining relative prices. Third, we build a two-product model where productivity changes lead to reallocations of labor between quantity production and quality innovation. The correlation between relative productivity and relative quality is negative for low-range substitutability and positive for medium-range substitutability between two products. Looking at services versus goods of the US, the correlation is negative and productivity-driven quality can play a significant role in general quality development.en
