A Triangular Treatment Effect Model With Random Coefficients In The Selection Equation

Hoderlein, Stefan; Gautier, Eric - Department of Economics, Boston College - 2012

unrestricted form, and the selection equation contains multiple unobservables that enter through a nonparametric random … identified. We can thus identify an average treatment effect, conditional on first stage unobservables called UCATE, which yields …0, Y1, given the unobservables. This allows to derive every treatment effect parameter, e.g. the distribution of …

Identification of Average Random Coefficients under Magnitude and Sign Restrictions on Confounding

Chalak, Karim - Department of Economics, Boston College - 2012

This paper studies measuring the average effects of X on Y in a structural system with random coefficients and confounding. We do not require (conditionally) exogenous regressors or instruments. Using proxies W for the confounders U, we ask how do the average direct effects of U on Y compare in...

Revealed Preferences in a Heterogeneous Population

Hoderlein, Stefan; Stoye, Jörg - Department of Economics, Boston College - 2009

This paper explores the empirical content of the weak axiom of revealed preference (WARP) for repeated cross-sectional data or for panel data where individuals experience preference shocks. Specifically, in a heterogeneous population, think of the fraction of consumers violating WARP as the...

Identifying Structural Effects in Nonseparable Systems Using Covariates

White, Halbert; Chalak, Karim - Department of Economics, Boston College - 2008

This paper demonstrates the extensive scope of an alternative to standard instrumental variables methods, namely covariate-based methods, for identifying and estimating effects of interest in general structural systems. As we show, commonly used econometric methods, specifically parametric,...
