This paper discusses the existing literature on migration and innovation, with special emphasis on empirical studies based on patent and inventor data. Other sources of micro-data are examined, too, for comparative purposes. A pilot database, based on patent filings at the European Patent Office is presented. It contains information on individual inventors, including their country of residence and of origin. Preliminary evidence suggests that immigrant inventors contribute to innovation not only in the United States, but also in selected European countries, where they often rank among the most productive individuals.

This paper has two objectives. First, it describes a new database mapping migratory patterns of inventors, extracted from information included in patent applications filed under the Patent Cooperation Treaty. It explains in detail the information contained in the database and discusses the usefulness and reliability of the underlying data. Second, the paper provides a descriptive overview of inventor migration patterns, based on the information contained in the newly constructed database.

This paper analyzes the gender of inventors in international patent applications. We compile a worldwide gender-name dictionary, which includes 6.2 million names for 182 different countries to disambiguate the gender of PCT inventors. Our results suggest that there is a gender imbalance in PCT applications, but the proportion of women inventors is improving over time. We also find that the rates of women participation differ substantially across countries, technological fields and sectors.

In this paper, the authors describe and explore a new algorithmic approach to constructing concordances between the International Patent Classification (IPC) system and industry classification systems that organize economic data. This ‘Algorithmic Links with Probabilities’ (ALP) approach incorporates text analysis software and keyword extraction programs and applies them to a comprehensive patent dataset. The authors conclude with a discussion on some of the possible applications of the concordance and provide a sample analysis that uses their preferred ALP concordance to analyze international patent flows based on trade patterns.

This study has emerged from an ongoing program of trilateral cooperation between WHO, WTO and WIPO. It responds to an increasing demand, particularly in developing countries, for strengthened capacity for informed policy-making in areas of intersection between health, trade and IP, focusing on access to and innovation of medicines and other medical technologies.

This paper explores the motivations of firms that disclose research outcomes in a scientific format. Besides considering an internal firm dimension, the authors focus particularly on knowledge sourcing from academic institutions and the appropriability regime using a cost-benefit framework. The analysis provides evidence that the access to important scientific knowledge imposes the adoption of academic disclosure principles, whereas the mere existence of collaborative links with academic institutions is not a strong predictor. Furthermore, the results suggest that overall industry conditions are influential in shaping the cost-benefit rationale of firms with respect to scientific disclosure.

Measuring Entrepreneurial Businesses: Current Knowledge and Challenges brings together and unprecedented group of economists, data providers, and data analysts to discuss research on the state of entrepreneurship and to address the challenges in understanding this dynamic part of the economy. Each chapter addresses the challenges of measuring entrepreneurship and how entrepreneurial firms contribute to economies and standards of living. The book also investigates heterogeneity in entrepreneurs, challenges experienced by entrepreneurs over time, and how much less we know than we think about entrepreneurship given data limitations. This volume will be a groundbreaking first serious look into entrepreneurship in the NBER's Income and Wealth series.
