This paper studies the role of quality competition in endogenous growth and institutional factors which can affect growth through affecting quality competition. The R&D-based growth literature as it stands attributes the incentives for innovations to monopolist market structure, and regards the...

We consider the dynamic relationship between product market entry regulation and equilibrium unemployment. The main theoretical contribution is combining a job matching model with monopolistic competition in the goods market and individual bargaining. We calibrate the model to US data and...

This paper investigates the impact of outsourcing on sectoral reallocation in the U.S. over the period 1947-2007, and on the rise in services in particular. Roughly 40% of the growth of the service sector comes from professional and business services. This is an unusual industry as more than 90%...

This paper investigates the impact of Information and Communication Technologies (ICT) on growth in an economy, consisting of three sectors, ICT-producing, ICT-using and non-ICT-using. The benefits from ICT come from the falling prices of the ICT-using sector’s good, which is used for the...

This paper develops an idea flows theory of trade and growth with heterogeneous firms. New firms learn from incumbent firms, but the diffusion technology ensures entrants learn not only from frontier technologies, but from the entire technology distribution. By shifting the productivity...

This paper reviews the cross-country record of economic growth, using as organizing framework how economic theory has guided that empirical analysis. The paper argues that recent studies of economic growth—both empirical and theoretical—distinguish from previous work in three distinct...

What factors underlie industry differences in research intensity and productivity growth? We develop a multisector growth model using standard parameters to capture the main factors considered in the empirical R&D and productivity growth literature. Along the balanced growth path, we find that...

We develop a multi-sector general equilibrium model in which productivity growth is driven by the production of sector-specific knowledge. In the model, we find that long run differences in total factor productivity growth across sectors are independent of the parameters of the knowledge...

This paper analyses a dynamic game of investment in R&D or advertising, where current investments change future market conditions. It investigates whether underinvestment can be supported in equilibrium by the threat of escalation in investment outlays. When there are no spillovers, or there is...

In this paper we develop a two-sector growth model of optimizing agents and apply this model to the data for the purpose of addressing the two interrelated questions that preoccupy the literature on development and growth accounting, namely: (1) What determines sustained growth and (2) What...
