Recent accounts suggest the development and commercialization of invention has become more "open." Greater division of labor between inventors and innovators can enhance social welfare through gains from trade and greater economies of specialization. Moreover, this extensive reliance upon...

The "market for innovation" -- the sale and licensing of patents -- is an often discussed source of incentives to invest in R&D. This article presents and estimates a model of the transfer and renewal of patents that, under some assumptions, allows us to quantify the gains resulting from the...

We present quantitative and qualitative evidence (field research) on university technology transfer offices (TTOs). These offices negotiate licensing agreements with firms to commercialize university-based technologies. A stochastic frontier production function framework is used to assess the...

In this paper I develop a positive theory of intergenerational transfers. I argue that transfers are a means to induce retirement. that is, to buy the elderly out of the labor force. The reason why societies choose to do such a thing is that aggregate output is higher if the elderly do not work....

This paper uses wavelets to decompose each stock's trading-volume variance into frequency-specific components. We find that stocks dominated by short-run fluctuations in trading volume have abnormal returns that are 1% per month higher than otherwise similar stocks where short-run fluctuations...

I study knowledge spillovers, positive externalities that augment the information set of an economic agent, and reviews the evidence on such spillovers in the context of international economic transactions. Even though spillovers are by their very nature difficult to identify, over recent...

While there is a vast body of research on the benefits of FDI in developing countries, whether and how the form of FDI matters have received limited attention. In this paper, we study the impact of FDI via quid pro quo (technology for market access) on facilitating knowledge spillover and...

This paper uses a large language model to develop an ex-ante measure of the commercial potential of scientific findings. In addition to validating the measure against the typical holdout sample, we validate it externally against 1.) the progression of scientific findings through a major...

We develop a new approach to dealing with real options problems with uncertain maturity. This type of situation is typical for R&D investments and mine or oil exploration projects. These types of projects are characterized by significant on-going investment costs until completion. Since time to...

This paper studies the investment activities of 44 independent oil and gas firms from 1978 to 1986. It develops a dynamic model of oil and gas exploration and development. The model predicts less of a decline in exploration activity than actually occurred in 1985-86. I consider the extent to...
