Fuzzy spatial models map a substantial degree of preference indifference. It has been shown that different definitions of covering result in different elements in the uncovered set when preference indifference is present. We consider several of the most frequently used definitions of covering...

This paper aims at opening the black box of peer effects in adolescent weight gain. Using Add Health data on secondary schools in the U.S., we investigate whether these effects partly flow through the eating habits channel. Adolescents are assumed to interact through a friendship social network....

This thesis considers a dynamic panel data model with error components that are correlated both spatially (cross-sectionally) and time-wise. The model extends the literature on dynamic panel data models with cross-sectionally independent error components. The model for spatial dependence is a...

Accurate regional estimates of output are desired as an indicator of level of development and as a variable used to explain internal migration, demand patterns, fertility and other aspects of behaviour. This chapter explores one often neglected aspect of regional income differences, namely that...

The paper focuses on the importance of the assumptions made about market structure andfirm behaviors in empirical trade policy analysis. It addresses this issue with reference torecent changes in the EU import regime for bananas, namely the Economic PartnershipAgreements and the December 2009...

Since its origins and numerous applications in material science, the Birnbaum-Saunders family of distributions has now found widespread uses in some areas of the applied sciences such as agriculture, environment and medicine, as well as in quality control, among others. It is able to model...

Die Repräsentationsbeziehung zwischen Wählern und Parteien ist entscheidend für das Funktionieren repräsentativer Demokratien. Der Grad der gefühlten Repräsentation hat Einfluss auf den Delegationsmechanismus und die Demokratiezufriedenheit. Daher untersucht dieser Artikel das...

Many economies are concerned with the future security of electricity supply. This is rooted in the necessity to decarbonise energy systems and in the nuclear phase-out. Hence, some economies, instead of investing in own domestic energy capacity, rely on energy production by their neighbours. At...

This paper presents the methodology of Markov chain Monte Carlos (MCMC) to statistical inference in Ecometrics. MCMC theory is reviewed and some relevant pratical aspects associated with convergence of the chain are discussed. The most common forms of MCMC using Gibbs sampling and the...
