It is well known that standard asymptotic theory is not valid or is extremely unreliable in models with identification problems or weak instruments [Dufour (1997, Econometrica), Staiger and Stock (1997, Econometrica), Wang and Zivot (1998, Econometrica), Stock and Wright (2000, Econometrica),...

We discuss statistical inference problems associated with identification and testability in econometrics, and we emphasize the common nature of the two issues. After reviewing the relevant statistical notions, we consider in turn inference in nonparametric models and recent developments on...

We study the problem of measuring the uncertainty of CGE (or RBC)-type model simulations associated with parameter uncertainty. We describe two approaches for building confidence sets on model endogenous variables. The first one uses a standard Wald-type statistic. The second approach assumes...

This paper tests for robust multidimensional poverty comparisons across six countries of the West African Economic and Monetary Union (WAEMU). Two dimensions are considered, nutritional status and assets. The estimation of the asset index is based on two factorial analysis methods. The first...

We propose a consumption-based capital asset pricing model in which the representative agent's preferences display state-dependent risk aversion. We obtain a valuation equation in which the vector of excess on equity includes both consumption risk as well as the risk associated with variations...

This paper develops a consumption-based asset pricing model in which attitudes towards risk are contingent upon the state of the world. For low (high) level of consumption relative to a subjective metric, counter-cyclical (pro-cyclical) risk aversion implies that consumption shocks generate...

We propose a consumption-based capital asset pricing model in which the representative agent's preferences display state-dependent risk aversion. Since a common factor - the state of the world - influences both stock prices and preferences, we obtain a valuation equation in which the vector of...
