In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors in the network benefit from each other's action levels through local complementarities and there exists a global interaction effect reflecting a strategic substitutability in...

Abstract I study how much consumers benefit from new products in markets with information frictions. I analyze new products in the U.S. hard drive market, a market characterized by ample product innovation. Using unique click-stream data, I measure the magnitude of two frictions, category...

We study social learning and innovation in an overlapping generations model, emphasizing the trade-off between marginal innovation (combining existing technologies) and radical innovation (breaking new ground). We characterize both short-term and long-term dynamics of innovation, and the...

This paper examines the use of social capital in the venture creation process. We compare solo entrepreneurs (n=182) and new venture teams (n=274) from a random sample of start-ups in innovative industries and test social capital use and its effects on firm performance. Our results reveal that...

Managers entrusted with new product development (NPD) have to seek the optimal balance between prior competencies and learning activities to generate successful products. Yet prior NPD research has largely taken a positivistic view of learning despite an inkling that too much learning can lead...

By including the effects of learning over time on both the production of components and their integration into complete products, we develop an engineering-based model of outsourcing. This model provides an alternative explanation for much of what other outsourcing theories predict, as well as...
