When innovation is cumulative, early patentees hold claims against later innovators. Then potential hold-up may cause prospective second stage innovators to forego investing in R&D. It is sometimes argued that ex ante licensing (before R&D) avoids hold-up. This paper explores ex ante licensing...

This paper presents a novel way automation can raise wages. Extending the Acemoglu-Restrepo model of automation to consider labor quality, we obtain a Remainder Effect: while automation displaces labor on some tasks, it raises the returns to skill on remaining tasks across skill groups. This...

Do high-tech startups benefit from developing more ethical AI? AI startups implement policies and take actions to manage ethical issues associated with data collection, storage, and usage and adapt to the norms of their industry. This paper describes these startups' ethics-related actions,...

How could such industries as software, semiconductors, and computers have been so innovative despite historically weak patent protection? We argue that if innovation is both sequential and complementary--as it certainly has been in those industries--competition can increase firms' future profits...

Innovative ideas have unique properties arising from low communication costs. But ideas come from knowledge that is costly to communicate. “Formalizing” knowledge — codifying, developing standards, etc. — reduces these costs. In a simple model, formalization is associated with changes in...

How should the economic performance of property systems be evaluated? Benefit-cost analysis is widely used to evaluate non-market based regulation when prices are not available. Market prices provide better information for property systems, but market prices are not necessarily socially optimal...

Solow (1957) decomposed labor productivity growth into two components that are independent under Hicks neutrality: input growth and the residual, representing technical change. However, when technical change is Hicks biased, input growth is no longer independent of technical change, leading to...
