In structural dynamic discrete choice models, unobserved and mis-measured state variables may lead to biased parameter estimates and misleading inference. In this paper, we show that instrumental variables can address such measurement problems when they relate to state variables that evolve...

regression of Y onto X in a subpopulation homogenous in W = w (formally a conditional linear predictor). Let b<sub>0</sub> (w) be … the coefficient vector on X in this regression. We introduce a semiparametrically efficient estimate of the average β … methods of semiparametric regression (e.g., the partially linear regression model) …

We formalize a noted [Guryan et al., 2009] but unexplored source of bias in peer effect estimation, arising because people cannot be their own peer. We derive, for linear-in-means models with non-overlapping peer groups, an exact formula of the bias in a test of random peer assignment. We...

We introduce a generalization of the RKD - the "fuzzy regression kink design" - that allows for … assignment variable and the policy variable. We also show how standard local polynomial regression techniques can be adapted to …
