| Abstract: | This paper uses the French and the UK Labour Force Surveys and German Microcensus to estimate the effects of the different components of the labour force on innovation at the sectoral level between 1994 and 2005, focusing in particular on the contribution of migrant workers. We adopt a production function approach in which we control for the usual determinants of innovation, such as R&D investments, stock of patents and openness to trade. To address for the possible endogeneity of migrants we implement instrumental variable strategies using both two-stage least squares with external instruments and GMM-SYS with internal ones. In addition we also account for the possible endogeneity of native workers and instrument them accordingly. Our results show that highly educated migrants have a positive effect on innovation even if the effect is smaller relative to the one of the educated natives. Moreover this positive effect seems to be confined to the high tech sectors and among highly educated migrants from other European countries. |

| Abstract: | This paper evaluates the current focus of EU policy makers on small and medium-sized, young independent firms in high-tech sectors. Therefore, the effect of subsidies on both R&D input and R&D output is compared between independent high-tech young firms (NTBFs), independent low-tech young firms (LTBFs) and their non-independent counterparts. A treatment effects analysis reveals that full crowding-out with regard to public funding is rejected for all firm types. However, the treatment effect is highest for independent high-tech firms. The indirect effect of subsidies on R&D output is evaluated within a patent production framework. These results show that independent high-tech firms have no lower output effects than other firms and thus suggest that the current policy focus on certain firm types is not ineffective. |

| Abstract: | The objective of this study is to compare the effect of different types of public support for R&D projects on firms’ technological capabilities. We distinguish be-tween low-interest loans and subsidies and between national and European sup-port. Using data on 4,407 Spanish firms during the period 2002-2005, we estimate a multivariate probit to analyse the determinants of firms’ participation in public R&D programmes and, later, the impact of this participation on firms’ technologi-cal capabilities using different indicators. The results provide evidence of the ef-fectiveness of all treatments for improving firms’ innovative performance. With respect to innovation outputs, apart from the indirect effect of public support by stimulating R&D intensity, we also find evidence of a direct effect of participation in the CDTI credit system and in the European subsidy programme on the probability of obtaining innovations and applying for patents. |

| Abstract: | In this paper we use cross-state panel data to show a positive and significant correlation between various measures of innovativeness and top income inequality in the United States over the past decades. Two distinct instrumentation strategies suggest that this correlation (partly) reflects a causality from innovativeness to top income inequality, and the effect is significant: for example, when measured by the number of patent per capita, innovativeness accounts on average across US states for around 17% of the total increase in the top 1% income share between 1975 and 2010. Yet, innovation does not appear to increase other measures of inequality which do not focus on top incomes. Next, we show that the positive effects of innovation on the top 1% income share are dampened in states with higher lobbying intensity. Finally, from cross-section regressions performed at the commuting zone (CZ) level, we find that: (i) innovativeness is positively correlated with upward social mobility; (ii) the positive correlation between innovativeness and social mobility, is driven mainly by entrant innovators and less so by incumbent innovators, and it is dampened in states with higher lobbying intensity. Overall, our findings vindicate the Schumpeterian view whereby the rise in top income shares is partly related to innovation-led growth, where innovation itself fosters social mobility at the top through creative destruction. |

| Abstract: | This paper posits that firms' corporate and technological diversification profiles and their relatedness in terms of products and technologies impact their propensity to form alliances for exploitation and exploration. The empirical investigation employs a dataset of all tire producers worldwide between 1985 and 1996 that combines detailed firm level data on establishment, patenting, and alliance activities. The results support these theoretical predictions and indicate that exploitative alliances are driven primarily by complementarity in terms of corporate diversification strategies, as well as partner characteristics (e.g., size, age, and technological capabilities). Moreover, firms with similar product portfolios but uneven technological performance are more likely to engage in exploitative interactions. In contrast, exploration alliances are driven by strong partner similarity across all firm characteristics and product portfolios. Both market and technological diversification have positive effects on the propensity to engage in explorative alliances while technological distance has a negative one. |

| Abstract: | Do the job-to-job moves of workers contribute to the cyclicality of employment growth at different types of firms? In this paper, we use linked employer-employee data to provide direct evidence on the role of job-to-job flows in job reallocation in the U.S. economy. To guide our analysis, we look to the theoretical literature on on-the-job search, which predicts that job-to-job flows should reallocate workers from small to large firms. While this prediction is not supported by the data, we do find that job-to-job moves generally reallocate workers from lower paying to higher paying firms, and this reallocation of workers is highly procyclical. During the Great Recession, this firm wage job ladder collapsed, with net worker reallocation to higher wage firms falling to zero. We also find that differential responses of net hires from non-employment play an important role in the patterns of the cyclicality of employment dynamics across firms classified by size and wage. For example, we find that small and low wage firms experience greater reductions in net hires from non-employment during periods of economic contractions. |
