After the initial breakthrough in the research phase of R&D a new product undergoes a process of change, improvement and adaptation to market conditions. We model the strategic behavior of firms in this development phase of R&D. We emphasize that a key dimension to this competition is the...

Cultural transmission arguably plays an important role in the determination of many fundamental preference traits (e.g., discounting, risk aversion and altruism) and most cultural traits, social norms, and ideological tenets ( e.g., attitudes towards family and fertility practices, and attitudes...

At each age an organism produces energy by foraging and allocates this energy among reproduction, survival, growth, and intergenerational transfers. We characterize the optimal set of allocation decisions that maximizes reproductive fitness. Time preference (the discount rate) is derived from...

Firm- and plant-level empirical studies typically find that trade liberalization squeezes price-cost margins among import-competing firms, that this heightened competitive pressure induces productivity gains among these same firms, and that further efficiency gains come from market share...

This paper documents the speed of evolution (or lack thereof) of a range of values and beliefs of different generations of US immigrants, and interprets the evidence in the light of a model of socialization and identity choice. Convergence to the norm differs greatly across cultural attitudes....

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

This research suggests that a Darwinian evolution of entrepreneurial spirit played a significant role in the process of economic development and the dynamics of inequality within and across societies. The study argues that entrepreneurial spirit evolved non-monotonically in the course of human...

Startups in IT and life sciences appear to be flourishing. However, startups in other sectors, such as new materials, automation, and eco-innovations, which are often called "deep tech", seem to struggle. We argue that innovations with both technical and commercial challenges, typical of deep...

We study how the inventive capability of a firm conditions its participation in a division of innovative labor. Capable firms are, by definition, able to invent; for them, external inventions substitute for their own R&D. However, external knowledge is an input into internal invention, and thus,...

This paper examines the relation between ownership, corporate form, and innovation for a cross-section of private and publicly traded innovating firms in the US and 15 European countries. A striking novel observation emerges from our analysis: while most innovating firms in the US are publicly...
