| Abstract: | Patent statistics represent a critical tool for scholars, statisticians and policy makers interested in innovation and intellectual property rights. Many analyses are based on heterogeneous methods delineating the inventors’ or firms’ patent portfolios without questioning the quality of the method employed. We assess different heuristics in order to provide a robust solution to automatically retrieve inventors in large patent datasets (PATSTAT). The solution we propose reduces the usual errors by 50% and casts doubts on the reliability of statistical indicators and micro-econometric results based on common matching procedures. Guidelines for researchers, TTOs, firms, venture capitalists and policy makers likely to implement a names game or to comment on results based on a names game are also provided. |

| Abstract: | Has upgrading and enforcing its patent laws slowed China’s economic growth? The answer we draw from detailed analysis of provincial aggregate data covering roughly the period 1990 through 2007 is strongly negative, but understanding the channels through which stricter protection of intellectual property rights has contributed to more rapid productivity growth is elusive. Our best estimate of the direct impact of the 1992 and 2001 patent laws on TFP growth amounts to not quite 15 percent of the average TFP growth rate over the period, but a much larger share of TFP growth is associated with enactment of the laws in a simple interpretation of our empirical investigation. We estimate that virtually none of the laws’ impact on TFP growth can be directly associated with increased quantity of FDI or R&D, although both series are strongly positively correlated with promulgation of the patent laws. We infer that amount of technology transfer through a FDI and the focus of R&D activity, decline of state ownership and increased marketization, growth of the human capital stock, and movement of the labor force from agriculture to manufacturing and service industries are all processes that were encouraged and whose effect has been magnified by stronger IPR protection. Moreover, adopting and enforcing the patent laws probably cannot be treated as an independent event with causation running in only one direction to China’s economic development.. |

| Abstract: | Using a comprehensive database of European firms, we study how private equity affects the rate of firm entry. We find that private equity investment benefits new business incorporation, especially in industries with naturally higher entry rates and R&D intensity. A two standard deviation increase in private equity investment explains as much as 5.5% of the variation in entry between high-entry and low-entry industries. We address endogeneity by exploiting data on laws that regulate private equity investments by pension funds. Our results hold when we correct for barriers to entry, general access to credit, protection of intellectual property, and labor regulations. JEL Classification: G24, L26, M13. |

| Abstract: | Universities are engaged in many activities; primarily, research and teaching. Many states have instituted performance measures that focus on evaluating a university's success in teaching. We suggest that multitasking may be important in this context, and we consider research outcomes after adoption. We find striking results that depend on university status. Research activity is higher at flagship institutions after the adoption of performance measures. Most of this increase in activity is with respect to the level of research funding and the number of articles produced. In contrast, research funding and the number of publications is dramatically lower at non-flagship institutions. There is some evidence that citations per publication at non-flagship institutions are higher after the adoption of performance standards. The evidence suggests that universities have become more specialized since the introduction of these programs. |
