This paper studies the event-history approach to microeconometric programevaluation. We present a mixed semi-Markov event-history model, discussits application to program evaluation, and analyze its empirical content.The results of this paper provide fundamental insights in what can be...

This paper studies the impact of collaboration on research output. First, we build a micro-founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...

To investigate the role of intra-regional trade integration on economic growth in Latin America, we develop a multilevel spatial production network model with time-varying parameters. The theoretical model is established for a multi-country and multi-sectoral economy. The reduced-form...

This paper examines international trade in tainted food and other low-quality products. Wefirst find that for a large class of environments, free trade is the trading system that conveysthe highest incentives to produce non-tainted high-quality goods by foreign exporters.However, free trade...

Understanding of the substantial disparity in health between low and high socioeconomic status (SES) groups is hampered by the lack of a suffciently comprehensive theoretical framework to interpret empirical facts and to predict yet untested relations. We present a life-cycle model that...

This paper focuses on the relation between the onset of disability and employment outcomes. We develop an event history model that includes unscheduled hospitalizations as a measure for unanticipated health shocks and estimate the model on data from the British National Child Development Study...

In this paper we evaluate the QALY loss, which may be assigned to the prevalence of specific chronic illnesses and physical handicaps. The analysis is based on an individual self-rating health satisfaction question asked in the British Household Panel Survey data set. This question provides a...

This paper presents a unified theory of human capital with both health capital and, what we term, skill capital endogenously determined within the model. By considering joint investment in health capital and in skill capital, the model highlights similarities and differences in these two...

We present a theory of human capital, with its two most essential components, health capital and, what we term, skill capital, endogenously determined within the model. Using the theory, and a calibrated version of it, we uncover and highlight an important economic mechanism driving...
