Knowledge-intensive entrepreneurship: sectoral patterns in a sample of European high-tech firms

This paper studies the relative importance of prior knowledge and resources available to a startup at the time of its founding across technologies. Our analysis is based on a survey submitted to the founders of new innovative ventures patenting in the biotech, electronics and medical devices technologies. Our findings show that pre-entry knowledge about customers’ needs and characteristics, about the technology and about potential suppliers and competitors differentially affect the technological and market entrepreneurial choice of the surveyed firms. These results suggest the existence of patterns of entrepreneurial activities that are technology-specific.     

Incentives and the structure of teams

This paper studies the relationship between moral hazard and the matching structure of teams. We show that team incentive problems may generate monotone matching predictions in the absence of complementarities in the production technology. Second, we analyze how complementarity in the underlying technology affects the matching predictions arising due to moral hazard. We find that (i) even when the production technology is strongly complementary, the incentive problem may lead to formation of negatively sorted teams; (ii) as the degree of complementarity increases, the optimal matching structure may switch from positive to negative, solely due to the need to provide incentives.     

Time–Space Harmonization of Consumer Price Indexes in Euro-Zone Countries

The objective of this paper is to discuss the possibilities of attaining a time–space harmonization of the consumer price indexes that are elaborated by the 12 European Union (EU) Euro-zone countries and by Eurostat. After focusing on the duality of the time and space domains for price indexes elaboration, the basic elements of the methodology of estimation of consumer price indexes are delineated, both in time and space. Then, the harmonization of formulae and baskets is outlined, with emphasis on the latter. The current system of surveys for price collection is reviewed and its limits are underlined, in order to suggest a methodology for a consumer basket harmonized approach which ensures better harmonized indexes comparability, reduction of list of products, and unification of quality adjustment methods.     

GIBSON'S PARADOX AND POLICY REGIMES: A COMPARISON OF THE EXPERIENCE IN THE US, UK AND ITALY

This paper compares the behaviour of long-term interest rates and prices in Italy, the UK and the USA, and seeks to shed light into what has become known as the 'Gibson Paradox'. We compare the various theoretical explanations for the observed positive correlation of interest rates and prices in the USA and the UK. Using both regression and frequency domain techniques, we demonstrate that there is little evidence for the occurrence of the paradox in the case of Italy. The key conclusion of the paper is that the comparative evidence from these three countries supports a gold standard interpretation of the Paradox.     

Remarks on uniqueness and strong solutions to deterministic and stochastic differential equations

Motivated by open problems of well posedness in fluid dynamics, two topics related to strong solutions of SDEs are discussed. The first one on stochastic flows for SDEs with non regular drift helps to solve a stochastic transport equation where the corresponding deterministic equation is not well posed. The second one is a concept of strong superposition solution motivated by problems where uniqueness is not true or not known.     

EMU fiscal indicators: a misleading compass?

The effectiveness of any device for fiscal discipline crucially depends on the indicators it refers to. This paper assesses the indicators adopted for fiscal rules in the European Economic and Monetary Union (EMU) with respect to their relevance for EMU’s objective of fiscal soundness and to the adequacy of the underlying statistical framework in providing conditions for enforcement. The paper argues that EMU’s deficit and debt indicators present several shortcomings with respect to both sustainability analysis and monitoring requirements. The debt indicator allows the achievement of targets via operations that do not improve fiscal sustainability and tends to underestimate overall outstanding liabilities. The deficit indicator cannot be monitored in a timely manner, allows too much room for discretion, and is subject to significant revisions. While acknowledging that any single indicator can be distorted when used as a policy target, the paper argues that the weaknesses of EMU’s indicators would be much reduced if consistency cross-checks played a larger role than they currently do.The authors wish to thank Claudia Braz, Carlo Cottarelli, Jorge Cunha, Mark De Broek, Albert␣Jaeger, Mohan Kumar, Joao Nogueira, Ethan Wiseman and the anonymous referees for helpful comments.
