I study an economy where oligopolistic firms establish in-house R&D programs to produce a continuous flow of cost-reducing (incremental) innovations. The scale of firms' R&D operations determines the rate of productivity growth. I first study the role of concentration, firm size, and demand,...

We estimate a standard production function with a new cross-country data set on business sector production, wages and R&D investment for a selection of 14 OECD countries including the United States. The data sample covers the years 1960-2004. The data suggest that growth differences can largely...

This paper studies the effects of public research (publications) and innovation output (patents) on national economic growth with the help of a GMM panel regression including 114 countries. Effects on productivity growth and capital and labor inputs are distinguished. Furthermore, different time...

Venture capital (VC) and growth are examined both empirically and theoretically. Empirically, VC-backed startups have higher early growth rates and initial patent quality than non-VC-backed ones. VC backing increases a startup's likelihood of reaching the right tails of the firm size and...

Conventional R&D-based growth theory argues that productivity growth is driven by population growth but the data suggest that the erstwhile positive correlation between population and productivity turned negative during the 20th century. In order to resolve this problem we integrate R&D-based...

Using data for six Asian miracle economies over the period from 1953 to 2006, this paper examines the extent to which growth has been driven by R&D and tests which second-generation endogenous growth model is most consistent with the data. The results give strong support to Schumpeterian growth...

In this paper we develop a model of invention and knowledge-diffusion. We show, in a setting of imperfect knowledge-transfers from one generation to the next, that there is a tension between the tendency for old knowledge to be lost on the one hand, and the tendency for preserved knowledge to be...

We develop a model where temporary non-technology shocks can lead to permanent changes in the rate of growth of total factor productivity (TFP). The key ingredient of the model is a matching processes between basic researchers, product developers, and the stock of knowledge of the economy. In...

We provide steps towards a welfare analysis of a two-country endogenous growth model where a relatively small follower absorbs part of the knowledge generated in the leading country. To solve a suitably defined infinite-horizon dynamic optimization problem a specialized version of the Pontryagin...
