The literature on both theoretical and empirical dynamics requires agents to solve complex dynamic programs, which assumes implicitly that agents are fully rational and have the most accurate expectations given their information set. We claim that this assumption is easily testable provided that...

Quite often, a firm has to decide between investing in a safe project (``small'') where rewards and losses remain moderate and a risky alternative (``big'') where the rewards and the losses are larger. We study such a choice in a context where the probability of success depends both on the...

This paper deals with the estimation of structural models of demand and supply with incomplete information on prices. When the seller is able to price discriminate, or the buyer to bargain, individuals pay different prices that are usually not collected in the data. This paper explores a method...

The assumption that consumers are fully rational and hold correct expectations over prices is demanding in dynamic settings. We claim that it is testable provided that market-level data on prices and purchases are available. We find that consumers hold simple expectations on the timing of...

In markets where sellers are able to price discriminate, or the buyers to bargain, individuals receive discounts over the posted prices that are usually not observed by the econometrician. This paper considers the structural estimation of a demand and supply model à la Berry et al. (1995) when...

Ex post evaluations are crucial to measure the empirical effects of public policies. At the same time, one can wonder how much of these effects could be anticipated ex ante. We address this question for the bonus/malus policy introduced in France to reduce co<indice>2</indice> emissions. This policy was, in...

In this paper, we investigate whether French consumers have modified their preferences towards environmentally-friendly vehicles between 2003 and 2008. We estimate a model of demand for automobiles incorporating both consumers’ heterogeneity and CO2 emissions of the vehicles. Our results show...
