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...

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),...

Cet article propose une analyse des rendements éducatifs issue du modèle de Mincer (1974). Dans le cas de Madagascar où plus de 50% des élèves étaient scolarisés dans une école privée en 1997, le type d’éducation reçue (publique ou privée) est pris en compte, tandis que les biais...

Land use changes generate some conflicts, in particular between agricultural and residential uses in the urbanization context and sprawl phenomena. Coastal zones also produce specific amenities that create conflicts over land-use, increase housing and land values and, associated with and/or...

The author constructs a formal analytic framework to simulate the impact of various economic shocks on the household debt-service ratio, using data from the Canadian Financial Monitor (CFM) survey. The impact of these shocks on individual households depends on the socio-economic characteristics...
