How many and which attributes are relevant for the sorting of agents in a matching market? This paper addresses these questions by introducing a novel technique called “Saliency Analysis” that is grounded in a continuous extension of the structural equilibrium model of Choo and Siow (2006). Saliency Analysis consists in estimating a quadratic joint utility(More)
An EDTA-blood sample from a cow without clinical signs, which gave early birth to a newborn calf that died soon after delivery, was shown to be positive for bluetongue virus (BTV)-RNA using a group-specific real-time RT-PCR (RT-qPCR). In-house serotype-specific RT-qPCR assays for bluetongue virus serotype 1 (BTV-1), -6 and -8 all gave negative results.(More)
Until recently, bluetongue (BT) virus (BTV) serotypes reportedly causing transplacental infections were all ascribed to the use of modified live virus strains. During the 2007 BT epidemic in Belgium, a significant increase in the incidence of abortions was reported. A study including 1348 foetuses, newborns and young animals with or without suspicion of BTV(More)
Bluetongue (BT) is an arthropod-borne viral disease of ruminants. In August 2006, domestic ruminant populations in Northern Europe became infected with BT virus serotype 8 (BTV-8). The first BTV-8-case of the year 2007 in Belgium was notified in July. This case was the starting point of a second wave of BT outbreaks. The main objective of this study was to(More)
Bluetongue (BT) was notified for the first time in several Northern European countries in August 2006. The first reported outbreaks of BT were confirmed in herds located near the place where Belgium, The Netherlands and Germany share borders. The disease was rapidly and widely disseminated throughout Belgium in both sheep and cattle herds. During the(More)
a r t i c l e i n f o We provide a normative analysis of endogenous student and worker mobility in the presence of diverging interests between universities and governments. Student mobility generates a university competition effect which induces them to overinvest in education, whereas worker mobility generates a free-rider effect for governments, who are(More)
Introduction 2 Introduction In developing countries, the ability of farm households to cope with risk is a key determinant of their daily livelihood. Poverty, food security and insurance issues are intrinsically linked to one another. This chapter elaborates on these issues, highlighting the relationship between self-and mutual insurance, and the way this(More)
This paper examines determinants of child labor and schooling with a special emphasis on birth order and sibling age structure. We present a theoretical model accounting for the dynamics of birth order and its interaction with credit constraints. We show that poor credit-constrained parents send their elder children to work relatively more. Since …rst borns(More)
