This paper discusses and illustrates identification problems in personality psychology. The measures used by psychologists to infer traits are based on behaviors, broadly defined. These behaviors are produced from multiple traits interacting with incentives in situations. In general, measures...

We model a three-pillar pension system and analyse in this context the impact of the financial crisis on the aggregate economy, using an overlapping generations model where individuals live for two periods. The system consists of (1) a PAYG pension system, (2) a Defined Benefit pension fund, and...

This paper proposes an assignment model where sorting occurs on attributes that are simultaneously a skill (Sattinger, 1979) and a preference (Tinbergen, 1956). The key feature of this model is that the wage function admits both jobs'' and workers'' attributes as arguments. Since this function...

We propose a model on strategic formation of communication networks with (i) link specificity: the more direct links somebody maintains, the less she can specify her attention per link, the lower her links’ value, while this negative externality was previously ignored in the communication...

This paper examines to what extent gazelles are the drivers of the growth of industries and structural change. To this purpose we analyze gazelles over a 12 year period (annually from 1997 until 2008) in the Netherlands, and relate them to the dynamics in employment per industry. We use a panel...

In a series of experiments conducted in Belgium (Wallonia and Flanders), France and theNetherlands, we compare behavior regarding tax evasion and welfare dodging, with and without information about others’ behavior. Subjects have to decide between a ‘registered’ income, the realization of...

We provide an explanation for the common finding that the effect of retirement on life satisfaction is negligible. For this we use subjective well-being measures for life and domains of life satisfaction that are available in the German Socio-Economic Panel (GSOEP) and show that the effect of...

We study duopolistic competition in a differentiated market with firms setting prices and quantities, without explicitly imposing market clearing. Unlike the commonly adopted assumption of profit maximizing firms, we assume firm behavior to be shaped by a Darwinian dynamic: the less fitter firm...

In this paper we investigate the economic integration - industrial specialization nexus and unravel the relationship between trade and financial openness and industrial specialization. For a panel of 31 countries over the period 1970 to 2005, we find that trade integration relates negatively to...

In this paper we consider an ILP-based approach to tackle the problem of determining a treewidth of the graph. We give an overview of existing attempts and develop further LP-based techniques for the problem. We present two different ILP formulations for the treewidth. To obtain the first one we...
