| Abstract: | Many empirical studies have confirmed the positive impact of innovation on productivity at the firm level. The focus tends to be either on R&D driven techno-logical innovation on the one hand, or on organisational changes complemented by ICT on the other. To investigate the effect of different types of innovations on produc-tivity, we propose a model with two innovation input equations (R&D and ICT) that feed into a knowledge production function consisting of a system of three innovation output equations (product innovation, process innovation and organisational innova-tion), which ultimately feeds into a productivity equation. We find that ICT is an im-portant driver of innovation in both manufacturing and services. Doing more R&D has a positive effect on product innovation in manufacturing. Organisational innova-tion has the strongest productivity effects. We only find positive effects of product and process innovation when combined with an organisational innovation. |

| Abstract: | This study examines the pattern of abnormal returns for merging companies and rivals to determine investor expectations regarding the impact of horizontal mergers challenged by the government. Prior studies have indicated that the government may have challenged efficiency-enhancing mergers as evidenced by the pattern of abnormal returns to rivals during merger events. This study examines those patterns using challenged mergers from 1997 to 2007, and it adds to the literature by assessing the effect that R&D intensity and change in HHI have on the returns to rivals and merging firms. The paper finds that the pattern of abnormal returns is a result of the different effects that antitrust complaints and merger outcomes have on rivals based on R&D intensity and change in industry concentration. This finding suggests that the government may have been properly vigilant in challenging mergers over the past 10 years in basic industries that have high levels of market concentration. However, it also may have allowed collusive mergers to proceed in R and D intensive industries. |

| Abstract: | This paper estimates the relationship between innovation and firm performance by using Community Innovation Survey data for Hungary. It exploits the possibility of linking the innovation data to ownership and disaggregated trade data. Innovative firms are more productive, more likely to trade and export into more countries. Foreign firms are more likely to innovate compared to similar domestic firms, but the amount of R&D is a weaker predictor of the innovative output of foreign firms. |

| Abstract: | Past research showed that exporters perform better than non-exporters in several domains, micro-level empirical evidence on the innovation-enhancing effect of export is, however, very scant. In this paper, we analyze the relationship between a firm's export status and its product innovation activity by using a rich firm-level survey on Italian manufacturing. First, we find that the positive effect of exporting on product innovativeness is robust to controlling for many sources of firm's observable heterogeneity and to allowing export activity to be endogenous. Second, we report evidence that the effect of exporting on product innovation is likely to be demand-driven, that is to originate from the interaction between domestic firms and foreign customers. |
