Through a stroke of luck, a referee report in the review process at the JPE has been positively identified as the Oberholzer-Gee/Strumpf (O/S) response to my earlier comment. Regardless of the response's provenance, what counts is whether it solidly refuted my comment. This 'sequel' analyzes the...

Using a sample of patents litigated between 1977 and 1997, I estimate stock market reactions to patent litigation decisions and to patent grants. I find that the resolution of uncertainty over validity and infringement is worth as much to the firm as the initial patent right. Each is worth about...

We analyze the impact of a Web-based trading channel on the trading activity in two corporate 401(k) plans. Using detailed data on about 100,000 participants, we compare trading growth in these firms to growth for a sample of firms without a Web channel. After 18 months of access, the inferred...

The focus of the paper was to conduct an analysis of the selected qualitative and quantitative aspects of the labour market and the potential ability of the young generation to adapt to the new conditions of their prospective employment. The primary data were obtained in the form of a...

This chapter addresses the history, use and significance of the term transaction costs. Few words in the economic language have been more abused or fought over and this is shown to result from the emergence of two distinct definitions and uses. The ‘Neoclassical’ definition rests on the...

In standard models of contracts, efficient incentives require the promisor to pay damages for non-performance and the promisee to receive no damages. To give efficient incentives to both parties, we propose a novel contract requiring the promisor to pay damages for nonperformance to a third...

We explore conditions under which collaboration between pharmaceutical firms from 'advanced' and emerging countries becomes preferable to rivalry. We show that that when agreements, such as Trade Related Aspects of Intellectual Property (IP) Rights, allow advanced country firms to take legal...

Might firms' use of data create market power? To explore this hypothesis, we craft a model in which economies of scale in data induce a data-rich firm to invest in producing at a lower marginal cost and larger scale. However, the model uncovers much richer interactions between data, welfare and...

This paper discusses contributions that industrial organization economists have made to our understanding of energy markets and environmental regulation. We emphasize the substantive contributions of recent papers while also highlighting how this literature has adopted and sometimes augmented...
