View Abstract
The recognition that information is, most of the time, incomplete and imperfect is essential in understanding the nature of the formation of beliefs. To understand human behavior in the area of (academic) performance, the beliefs individuals sustain about their ability become crucial. Before performing a certain task, the agent never knows his/her true ability. He/she only has an ex-ante notion of his/her believed ability and the truth is only revealed ex-post. Once the true ability is known and the payoffs realized, we observe different reactions that range from disappointment to happiness. The logical question is then, who would have preferred not to know the truth? This paper deals with the information acquisition decisions of individuals who face uncertainty about their own ability. At a theoretical level (Bénabou and Tirole, 2002), it has been shown that overconfident individuals (people with beliefs about themselves higher than reality) with time inconsistent preferences have more at stake when they face the decision of learning the truth about themselves than more pessimistic agents. To test this prediction, a field experiment is designed and implemented, where students face the decision of learning, or not, their true ability before performing a test. It will be shown that overconfident students indeed more often decide not to learn their true ability.

View Abstract
At a competitive equilibrium of an incomplete-markets economy agents’ marginal valuations for the tradable assets are equalized ex-ante. We characterize the finest partition of the state space conditional on which this equality holds for any economy. This leads naturally to a necessary and sufficient condition on information that would lead to retrade, if such information were to become publicly available after the initial round of trade.

View Abstract
We show that individuals who are in poorer health, independently from smoking, are more likely to start smoking and to smoke more cigarettes than those with better non-smoking health. We present evidence of selection, relying on extensive data on morbidity and mortality. We show that health based selection into smoking has in- creased over the last fifty years with knowledge of its health effects. We show that the effect of smoking on mortality is higher for high educated individuals and for individuals in good non-smoking health.

View Abstract
This paper analyzes the life-cycle career costs associated with child rearing and decomposes their effects into unearned wages (as women drop out of the labor market), loss of human capital, and selection into more child-friendly occupations. We estimate a dynamic life-cycle model of fertility, occupational choice, and labor supply using detailed survey and administrative data for Germany for numerous birth cohorts across different regions. We use this model to analyze both the male-female wage gap as it evolves from labor market entry onward and the effect of pro-fertility policies. We show that a substantial portion of the gender wage gap is explainable by realized and expected fertility and that the long-run effect of policies encouraging fertility are considerably lower than the short-run effects typically estimated in the literature.

View Abstract
This paper shows that smoking intensity, i.e. the amount of nicotine extracted per cigarette smoked, responds to changes in excise taxes and tobacco prices. We exploit data covering the period 1988 to 2006 across many US states. Moreover, we provide new evidence on the importance of cotinine measures in explaining long-run smoking behavior and we investigate the sensitivity of smoking cessation to changes in excise taxes and their interaction with smoking intensity.
