| Abstract: | This study shows for a large sample of R&D-active manufacturing firms over the period 2000-2009 that knowledge alliances have a positive effect on patenting in terms of both quantity and quality. However, when distinguishing between alliances that aim at joint creation of new knowledge and alliances that aim at the exchange of knowledge, results suggest that creation alliances lead to more valuable patents as they receive significantly more forward citations per patent. Knowledge exchange alliances, on the other hand, are associated with patent quantity, but not quality. -- |

| Abstract: | This study analyses the impact and effectiveness of targeted public support for R&D investment at the firm level. We test whether the policy design aiming at incentivizing (international) collaboration and R&D in SMEs achieves input as well as output additionality. Our results show that the targeted public subsidies trigger R&D spending, especially so in internationally collaborating SMEs. We further evaluate the different impact of privately financed and publicly-induced R&D investment on innovation performance. The results confirm that the publicly-induced R&D is productive as it translates into marketable product innovations. While both types of R&D investments trigger significant output effects, the effect of policyinduced R&D investment on sales from market novelties is highest for international collaborators as well as for SMEs. -- |

| Abstract: | In a two-firm model where each firm sells a high-quality and a low-quality version of a product, customers differ with respect to their brand preferences and their attitudes towards quality. We show that the standard result of quality-independent markups crucially depends on the assumption that the customers' valuation of quality is identical across firms. Once we relax this assumption, competition across qualities leads to second-degree price discrimination. We find that markups on low-quality products are higher if consuming a low-quality product involves a firm-specific disutility. Likewise, markups on high-quality products are higher if consuming a high-quality product creates a firm-specific surplus. |

| Abstract: | This paper develops a general equilibrium model of international trade with heterogeneous firms and imperfect credit markets. To finance the costs for product innovation and domestic and foreign market entry, firms must raise external capital. The model underscores the importance of considering a general equilibrium setting in order to characterize fully the misallocations of resources that stem from the existence of credit frictions. These have important implications for firms' entry decisions in the different markets and for the welfare effects of imperfect financial institutions. Allowing for liquidity-constrained firms and imperfect credit markets alters, and in some cases reverses, some of the main results from the literature on heterogeneous firms. In particular, the model predicts that trade liberalization does not necessarily lead to an increase in average productivity and consumers' welfare. |

| Abstract: | This paper studies structural changes underlying China's remarkable and unprecedented growth in recent years. While patterns of structural transformation across China's provinces are broadly in line with international experience, one important difference is in labor productivity differentials between services and the rest of the economy. Specifically, the gap between labor productivity in the rest of the economy and services has widened across China's provinces as they have moved from low to middle income, which is contrary to the trend observed in cross-country experience. Evidence from a panel of China's provinces suggests that credit and labor market frictions have inhibited labor productivity growth in services relatively more than in the rest of the economy. Reducing these frictions is essential for achieving the next stage of China's development, one in which the service sector will need to play a more prominent role as an engine of growth. The evidence also suggests that improving labor productivity in services will lift the consumption share of GDP, thereby advancing the needed rebalancing of domestic demand in China. |
