Agglomeration economies and location choice: Foreign direct investment in Hungary1

Since the beginning of the transition process, Hungary has attracted a significant amount of foreign direct investment (FDI), although this is unevenly distributed among the twenty Hungarian counties. This paper examines the determinants of FDI at a regional level in Hungary and more particularly assesses the importance of agglomeration effects among determinants. A panel model of the location determinants of FDI in Hungary is developed and estimated. Empirical testing suggests that counties with higher labour availability, greater industrial demand and higher manufacturing density attract more FDI. Surprisingly, higher unit labour costs attract FDI. In addition, inter‐industrial agglomeration economies and infrastructure availability are found to be important.     

Marketing of cultural institutions in French-speaking Switzerland

• Marketing in cultural institutions is a field that has rarely been studied in French-speaking Switzerland so far.
• Therefore this paper explores the way in which visitors-clients appreciate qualitatively their contacts with cultural institutions concerned with the visual arts in comparison with the communication strategy of the curators and directors of museums.
• A survey has been conducted amongst 20 museums and over 200 visitors of French-speaking Switzerland to evaluate the way visitors perceive the marketing of cultural institutions and behave accordingly or not.
• The paper concludes with recommendations to improve the knowledge of the visitors' background and expectations.

BIG data – BIG gains? Understanding the link between big data analytics and innovation

ABSTRACT

This paper analyzes the relationship between firms' use of big data analytics and their innovative performance in terms of product innovations. Since big data technologies provide new data information practices, they create novel decision-making possibilities, which are widely believed to support firms' innovation process. Applying German firm-level data within a knowledge production function framework we find suggestive evidence that big data analytics is a relevant determinant for the likelihood of a firm becoming a product innovator as well as for the market success of product innovations. These results hold for the manufacturing as well as for the service sector but are contingent on firms' investment in IT-specific skills. Overall, the results support the view that big data analytics have the potential to enable innovation.     

Nonparametric density estimation in compound Poisson processes using convolution power estimators

Consider a compound Poisson process which is discretely observed with sampling interval $\Delta $ until exactly $n$ nonzero increments are obtained. The jump density and the intensity of the Poisson process are unknown. In this paper, we build and study parametric estimators of appropriate functions of the intensity, and an adaptive nonparametric estimator of the jump size density. The latter estimation method relies on nonparametric estimators of $m$ th convolution powers density. The $L^2$ -risk of the adaptive estimator achieves the optimal rate in the minimax sense over Sobolev balls. Numerical simulation results on various jump densities enlight the good performances of the proposed estimator.     

ICT and global sourcing – evidence for German manufacturing and service firms

This paper analyses the relevance of information and communication technologies (ICT) for firms’ probability of global sourcing of inputs. Using firm-level data from Germany in 2009, which include mainly small and medium-sized firms, the empirical analysis differentiates between manufacturing and service firms. The results show some differences between the manufacturing and service sector. Controlling for various sources of firm heterogeneity, the global sourcing probability is increasing in the firms’ share of employees with Internet access in the manufacturing sector. E-commerce-intensive firms are more likely to source inputs from abroad but generally, this relationship between e-commerce and global sourcing is only robust in services and much stronger there than in manufacturing. In both sectors, it is strongest in industries with higher upstream industry diversity. Moreover, labour productivity is positively linked to global sourcing. The findings support arguments for the importance of the Internet for global trade.     

The effects of direct storage subsidies under limited rationality: a general equilibrium analysis

We study here the effects of a public subsidy to private storage set up at world level. To simulate the welfare effects and impacts on market fluctuations of this subsidy, we use a dynamic Computable General Equilibrium model assuming imperfect expectations. We also perform different statistical analysis based on our CGE results and show that the storage subsidy can have the undesired effect of destabilizing agricultural markets, depending on the form of economic agents’ price expectations and on the structure of the shocks impacting the agricultural production.     

Spline regression for hazard rate estimation when data are censored and measured with error

In this paper, we study an estimation problem where the variables of interest are subject to both right censoring and measurement error. In this context, we propose a nonparametric estimation strategy of the hazard rate, based on a regression contrast minimized in a finite‐dimensional functional space generated by splines bases. We prove a risk bound of the estimator in terms of integrated mean square error and discuss the rate of convergence when the dimension of the projection space is adequately chosen. Then we define a data‐driven criterion of model selection and prove that the resulting estimator performs an adequate compromise. The method is illustrated via simulation experiments that show that the strategy is successful.     

GENDER AND THE FOUNDATIONS OF SOCIAL CHOICE: THE ROLE OF SITUATED AGENCY

Amartya Sen defends a rich conception of social choice theory against tendencies to limit social choice theory to the formal investigation of rules of collective decision-making. His understanding of social choice theory makes the field a natural candidate for exploring gender issues in the evaluation of democratic policy. Not surprisingly, Sen has applied the insights he developed from his study of social choice to the evaluation of gender inequality, in particular to women's well-being in the context of the family. I focus on Sen's distinction between well-being and agency, and argue that from the perspective of women's movements and related social movements, the role of agency has so far been unduly neglected in social choice theory.     

Zielgruppenorientierung und Hybridität als Marketingtreiber im Direktvertrieb

Durch die rasche Verbreitung neuer Vertriebskan?le stellt sich die Frage, wie die Marketinginstrumente zur Steigerung des Vertriebserfolges optimal aufeinander abgestimmt werden k?nnen. Bei der Suche nach einer effektiven Marketinglogik setzt die Oswald Nahrungsmittel GmbH in erster Linie auf eine Kombination von Zielgruppenorientierung und hybriden Vertriebsstrukturen — und hat beispielsweise so die Effektivit?t einer Direct-Mailing-Kampagne gesteigert.
