Research Efficiency in Manufacturing: An Application of DEA at the Industry Level

This paper analyzes research efficiency at the industry level in manufacturing for 13 European member and four nonmember countries during 2000 and 2004. A unique dataset was compiled that matches patent applications at the European Patent Office (EPO) to industry-specific R&D inputs from EU KLEMS. We find that Germany, the United States, and Denmark have the highest efficiency scores on average in total manufacturing. The main industries that are at the technology frontier are those involved in electrical and optical equipment and machinery. Separate frontier estimations for these industries, conducted without the constraint of a constant technology frontier, provide additional support for our results

Divergent mind-sets, convergent policies: Policing models against organized crime in Italy and in England within international frameworks

The fight against organized crime is a very fertile ground for policymaking at various levels. On one side, because of the perceived transnationality of the phenomenon, national states are inclined to develop harmonized responses within the European or international law frameworks. On the other side, national conceptualizations and manifestations of organized crime often make these harmonizations quite challenging. This paper shares the findings of a socio-legal investigation carried out in England and in Italy through interviews and document analysis, comparing the two national models against organized crime. The paper presents these two models ? the Italian Structure Model and the English Activity Model, which are very different in many ways ? in order to identify divergences and convergences of policies and practices. This comparative exercise not only improves our understanding of national approaches, beyond cultural, linguistic and legal boundaries, but also improves the dialogue towards concerted efforts at the international level. Nevertheless, the globalization of criminal markets and the internationalization of policies have influenced perceptions of organized crime and related policing tactics at national levels too. This paper will briefly look at international perspectives to assess to what extent divergent and convergent areas between the two models are also areas of interest and focus at the international level, in order to conclude with an enhanced understanding of both models before drawing conclusions

Entry Regulations, Product Differentiation and Determinants of Market Structure

We use a dynamic oligopoly model of entry and exit to evaluate how entry regulations affect profitability and market structure in retail. The model incorporates demand and store-level heterogeneity. Based on unique data for all retail food stores in Sweden, we find that the average entry costs for small and large stores are 10 and 18 percent lower, respectively, in markets with liberal compared with restrictive regulations. Counterfactual simulations show that lower entry costs in restrictive markets result in higher entry rates and allow us to quantify the consequences of regulations in light of trade-offs between small and large stores

Determinants of Green Innovation: The Impact of Internal and External Knowledge

Based on a comprehensive data set comprising 13 countries, 22 industries and a period of 30 years we investigate the impact of internal and external knowledge pools of both green and other than green technologies on green patent activities. It turned out that the internal green knowledge stock is positively related to green patent activities with a considerably large marginal value. The country's green knowledge stock and the green knowledge stock of the same industry in other countries are also positively related with industries' green patent activities, although with a significantly lower marginal value. External other than green knowledge stocks are negatively related with green inventions. The considerable greater marginal value for internal green knowledge stock indicates that a free-riding position on green technology investments of other industries in the same country or the same industry in other countries does not seem to be very promising in terms of green inventions. The negative marginal effect of external other than green knowledge stocks and the positive marginal value of external green knowledge stocks indicate that country level policy measures to promote green knowledge formation would provide additional positive effects for green inventions on an industry level
