Public knowledge partnerships in European research projects and knowledge creation across R&D institutional sectors

This paper investigates the role of public knowledge partnerships in EU-funded framework programmes (FP) on knowledge creation across a sample of European countries. Different from previous studies, we investigate whether the impact of participation in FP on new knowledge (patents) differs across private companies, universities and public research centres. We find that, while all institutional sectors benefit from joint projects, the main benefits (in terms of patenting activity) go to universities and public research centres, while private companies benefit less. We also find evidence of important complementarities between participation in international research projects and internal innovation drivers (researchers), thus highlighting the crucial role of domestic absorptive capacity for fully benefiting from international cooperation in R&D projects.     

Cournot-Walras equilibria in markets with a continuum of traders

Summary In a model with a nonatomic continuum of traders some of which behave strategically while the others remain price-takers, the set of Cournot-Walras equilibria coincides with the set of Walras equilibria. This property is no longer valid when the strategic agents are represented by atoms.It is a pleasure to acknowledge the stimulating discussions we had with R. Amir about the question examined in the present work.     

The economic debate on power: a Marxist critique

In the economic debate on power, seemingly opposite positions have been presented. Contractualists have claimed that power relations do not exist in capitalism, and radicals have maintained that they are ubiquitous. In the middle, transaction costs and property rights economists have argued that power relations exist only within the firm. The underlying conception, however, is the same: power is an interpersonal relation caused by imperfections in the decision-making context and is incompatible with Walrasian competition. The difference among these theories involves their viewpoints on the concrete spread of imperfections in reality. The thesis of this paper is that this narrow conception of power is a consequence of neoclassical methodology. Following Marx, I analyze power as a social relation, and I discuss three problematic aspects of the neoclassical conception: its individualistic methodology, the assumption of universal rather than historical categories, and an ontology that conflates production and circulation.     

Financial and economic determinants of firm default

This paper investigates the relevance of financial and economic variables as determinants of firm default. Our analysis covers a large sample of medium-sized limited liability firms. Since default might lead, through bankruptcy or radical restructuring, to firm’s exit, our work also relates to previous contributions on industrial demography. Using non parametric tests we assess to what extent defaulting firms differ from the non-defaulting group. Bootstrap probit regressions confirm that economic variables, in addition to standard financial indicators, play both a long and short term effect. Our findings are robust with respect to the inclusion of Distance to Default and risk ratings among the regressors.     

Innovation and economic performance in services: a firm-level analysis

This paper explores the two-way relationship between innovationand economic performance in services using a longitudinal firm-leveldataset which matches data from the second Community InnovationSurvey, CIS II (1993–95), against a set of economic variablesprovided by the System of Enterprise Accounts (1993–98).The results presented show that innovation is positively affectedby past economic performance and that innovation activities(especially investments in ICTs) have a positive impact on bothgrowth and productivity. Furthermore, productivity and innovationact as a self-reinforcing mechanism, which further boosts economicperformance. These findings provide empirical support for theendogenous nature of innovation in services and the presencein this sector of competition models and selection mechanismsbased on innovation.     

The impact of innovation on economic performance in services

This article empirically explores the relationship between innovation and economic performance in services at the firm level. The empirical analysis is based on a unique longitudinal firm-level data set, which matches the Italian Community Innovation Survey (CIS II) data (1993–1995) and a set of economic indicators provided by the Italian System of Enterprise Account (1993–1998). In particular the empirical analysis aims at assessing whether the presence of innovation and the amount of resources devoted to innovation are able to explain the economic performance of firms in the service sector. The results presented show that innovating firms out perform non-innovating firms in terms of productivity levels and economic growth. Productivity is also found to be linked to the amount of innovation expenditures, especially those devoted to the acquisition and internal development of new software.     

THE CHOICE OF THE AGGREGATION LEVEL IN THE ESTIMATION OF QUARTERLY NATIONAL ACCOUNTS

Many central statistical offices use indirect time series disaggregation methods to produce quarterly national accounts estimates or other high frequency variables. This paper investigates the relation existing between the statistical properties of indirectly estimated time series and the contemporaneous aggregation level at which estimation is carried out, when a version of the Chow-Lin (1971, 1976) method is used to evaluate quarterly time series. It is shown that estimation at the lowest possible level of contemporaneous aggregation is not always optimal. In order to choose the level of contemporaneous aggregation at which time series disaggregation should be carried out, the use of formal econometric tests is suggested.     

Fish market integration and demand analysis: a Mediterranean case study

This study discusses the importance of delineating market boundaries prior to undertaking demand analysis. The Northern Adriatic Sea is considered a good case study by which to test this approach, given the richness of species landed there and their heterogeneous distribution across the space involved. Three groups of demersal species (whitefish, cephalopods, and crustaceans) are chosen for the study. First, geographical market boundaries are defined for each product (species) using price–price relations between market places. Second, demand is analyzed inside the defined market area through the linear approximation of the inverse almost ideal demand system. Geographical market integration bears several patterns of complete or partial integration, depending on the species. It could be said that integration is higher for species of high economic relevance among regions where large quantities are landed. For all product groups, our estimations suggest that moderate substitution effects do exist among species. The characteristics of the fleets and of the buyers, as well as the biophysical attributes of the sea basin (i.e., species richness and heterogeneous spatial distribution) are discussed as explanatory variables of market integration/segmentation.
