We survey the economic literature, both theoretical and empirical, on the choice of intellectual property protection by firms. Our focus is on the tradeoffs between using patents and disclosing versus the use of secrecy, although we also look briefly at the use of other means of formal...

We analyze the patent filing strategies of foreign pharmaceutical companies in Chile distinguishing between “primary” (active ingredient) and “secondary” patents (patents on modified compounds, formulations, dosages, particular medical uses etc.). There is prior evidence that secondary...

A surprisingly small number of innovative firms use the patent system. In the UK, the share of firms patenting among those reporting that they have innovated is about 4%. Survey data from the same firms support the idea that they do not consider patents or other forms of registered IP as...

Global climate change mitigation will require the development and diffusion of a large number and variety of new technologies. How will patent protection affect this process? In this paper we first review the evidence on the role of patents for innovation and international technology transfer in...

This paper explores the characteristics of 238 patents on 94 "inventions" contributed by major multinational innovators to the "Eco-Patent Commons", which provides royalty-free access to third parties to patented climate change related innovations. By comparing the pledged patents to other...

A number of studies have tried to gauge the effect of international trade on the rising U.S. skill premium by examining whether product prices in unskill-intensive sectors have fallen relative to prices in skill-intensive sectors. However, these studies do not estimate what share of domestic...

Firms that export or, even more so, are part of a multinational enterprise tend to exhibit higher productivity than their purely domestic counterparts. To better understand this correlation, we incorporate the perspective of industrial organization that one of the main drivers of differences in...

We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price (LOOP). For identical products, we find typical deviations of twenty to fifty percent, though there is muted evidence for convergence over time. Such...

This paper examines whether the sector bias of skill-biased technical change (sbtc) explains changing skill premia within countries in recent decades. First, using a two-factor, two-sector, two-country model we demonstrate that in many cases it is the sector bias of sbtc that determines sbtc's...

The U.K. skill premium fell from the 1950s to the late 1970s and then rose very sharply. This paper examines the contributions to these relative wage movements of international trade and technical change. We first measure trade as changes in product prices and technical change as TFP growth....
