Networking and the giving and receiving of advice outside of one's own firm are important features of entrepreneurship and innovation. We study how immigrants and natives utilize the potential networking opportunities provided by CIC, formerly known as the Cambridge Innovation Center. CIC is...

In many countries holders of patents must pay an annual renewal fee in order to keep their patents in force. This paper uses data on the proportion of patents renewed, and the renewal fees faced by, post World War II cohorts of patents in France, the United Kingdom, and Germany, in conjunction...

We report the results of the first comparative study of the determinants and effects of patent oppositions in Europe and of re-examinations on corresponding patents issued in the United States. The analysis is based on a dataset consisting of matched EPO and US patents. Our analysis focuses on...

Until the 1990's, US markets were more competitive than European markets. Today, European markets have lower concentration, lower excess profits, and lower regulatory barriers to entry. We document this surprising outcome and propose an explanation using a model of political support. Politicians...

This paper introduces a new internationally comparable data set that permits an empirical investigation of the effects of patent law on innovation. The data have been constructed from the catalogues of two 19th century world fairs: the Crystal Palace Exhibition in London, 1851, and the...

How will countries handle idiosyncratic national macroeconomic shocks under the European single currency? The ways in which European countries now react to internally asymmetric shocks provide a better forecast than do the regional response pattern of the United States. In this paper we compare...

Casual observation indicates that in recent years real interest rates in the United States appear to have risen sharply and have remained high relative to historical standards. Many observers have claimed that these high real rates have been transmitted abroad and have lead to high real rates in...

Economic and social historians have traditionally been concerned to measure changes in the income and welfare of populations in the past.Until recently, however, they have not recognized that anthropometric data, such as evidence on the average height achieved by a population at a particular...

We examine the relationship between immigration and attitudes toward redistribution using a newly assembled data set of immigrant stocks for 140 regions of 16 Western European countries. Exploiting within-country variations in the share of immigrants at the regional level, we find that native...

By merging KLEMS data sets and aggregating over the ten largest Western European nations (EU-10), we are able to compare and contrast productivity growth up through 2015 starting from 1950 in the U.S. and from 1972 in the EU-10. Data are provided at the aggregate level, as well as for 16...
