To date, the phenomenon of entrepreneurship has lacked a conceptual framework. In this note we draw upon previous research conducted in the different social science disciplines and applied fields of business to create a conceptual framework for the field. With this framework we explain a set of empirical phenomena and predict a set of outcomes not explained or predicted by conceptual frameworks already in existence in other fields.

The Promise of Entrepreneurship as a Field of Research

计量经济分析 = Econometric analysis

This survey reviews the growing use of patent data in economic analysis. After describing some of the main characteristics of patents and patent data, it focuses on the use of patents as an indicator of technological change. Cross-sectional and time-series studies of the relationship of patents to R&D expenditures are reviewed, as well as scattered estimates of the distribution of patent values and the value of patent rights, the latter being based on recent analyses of European patent renewal data. Time-series trends of patents granted in the U.S. are examined and their decline in the 1970s is found to be an artifact of the budget stringencies at the Patent Office. The longer run downward trend in patents per R&D dollar is interpreted not as an indication of diminishing returns but rather as a reflection of the changing meaning of such data over time. The conclusion is reached that, in spite of many difficulties and reservations, patent data remain a unique resource for the study of technical change.

Patent Statistics as Economic Indicators: A Survey

To assess the effects of a firm's network of relations on innovation, this paper elaborates a theoretical framework that relates three aspects of a firm's ego network—direct ties, indirect ties, an...

Collaboration Networks, Structural Holes, and Innovation: A Longitudinal Study:

Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

In this study, we quantify the role of foreign-born founders in high-tech entrepreneurship in a nationally representative sample of rapidly growing "high-impact" companies. This class of companies drives job creation and aggregate growth in the U.S. We find that, while most previous studies have overstated this role, it is nonetheless very important. For instance, about 16% of the companies in our sample had at least one foreign-born person among their founding teams, and these high-tech companies display better performance in some respects than high-tech companies in our sample whose founders were all native-born. We also provide a profile of high-tech immigrant entrepreneurs. The vast majority are strongly rooted in the U.S., highlighting the need to build a coherent pathway to permanent status for highly-skilled immigrants.

Public policy in an entrepreneurial economy : creating the conditions for business growth

If present increases in the rate of obesity persist, by 2015 half of the population in the US could be obese. This article presents the case that the reason for the epidemic is an ‘infrastructure of obesity’ that fuels the phenomenon. To control this epidemic, public policy in general and health policy in particular need to shift from market oriented policies that favour individual choice to policies that regulate the food supply, to help dismantle the infrastructure of obesity. Our research shows that state regulations have made some progress in the fight against obesity.
