This paper studies models for discrete outcomes which permit explanatory variables to be endogenous. In these models there is a single nonadditive latent variate which is restricted to be locally independent of instruments. The models are incomplete; they are silent about the nature of dependence between the latent variate and the endogenous variable and the role of the instrument in this relat...

The effects of improving covariate measurement are investigated when the covariate is endogenous even in the absence of measurement error. Reducing measurement error can exacerbate the finite sample bias of Two-Stage Least Squares. An application reveals this is of practical importance. JEL: C36, C81

We analyze how residential water consumption is influenced by the of households belonging to same social group (peer effect). Analyses are based on household-level data provided Brazilian Household Budget Survey and use an innovative strategy that estimates spatial dependence while simultaneously controlling for potential sources sample selectivity endogeneity. The our quantile regression model...
