We present a model of science-based entrepreneurship where ideas initially produced by researchers with high-level knowledge capital may be developed by high-ability entrepreneurs. With moderate investment costs, startups continuously managed by inventors-founders coexist in equilibrium with...

The conventional view of science-based businesses focuses on the inseparability of the roles of the inventor generating the underlying idea and the Schumpeterian entrepreneur who implements it in practice. We present an equilibrium model of science-based entrepreneurship where scientific ideas...

We explore how firms grow by adding products. In contrast to most earlier work on the topic, our conceptual and empirical framework allows for separate treatment of product innovation (vertical differentiation) and diversification (horizontal differentiation). The market context is Japan's...

Case studies reveal a pattern of rapid industrial growth propelled by innovation and quick diffusion of new technologies, especially among emerging industries exposed to global competition. At the firm level, the distribution of innovative activity is highly skewed, while productivity growth is...

Based on recent findings concerning the best performing start-ups, we develop a model of Schumpeterian entrepreneurship in which founders exploit ideas they learned through their employment. The model yields distinctive implications about how labor market experience and earnings at work...
