We develop non-parametric instrumental variable estimation and inferential theory for econometric models with possibly endogenous regressors whose coefficients can vary over time either deterministically or stochastically, and the time-varying and uniform versions of the standard Hausman...

We show that the contemporaneous and longer horizon impulse responses estimated using small-scale Proxy structural vector autoregressions (SVARs) can be severely biased in the presence of information insufficiency. Instead, we recommend the use of a Proxy Factor Augmented VAR (FAVAR) model that...

In this paper, football data from the 2007/2008 to 2016/2017 seasons of the Italian Serie A were used to identify the effects of replacing a coach mid-season due to poor team performance. We used an instrumental variable approach to correlate coach turnover within a season with player...

We estimate the effects of the arrival of 2.5 million Syrian migrants in Turkey by the end of 2015 on the labor market outcomes of natives, using a difference-in-differences IV methodology. We show that relaxing the common-trend assumption of this methodology -unlike recent papers in the same...

This paper examines the effects of policy rate announcements on households' inflation expectations over the time period 2003-2015. The effect is estimated using a two-stage least squares regression model. The announced changes are instrumented by a monetary policy surprise variable obtained from...

This paper considers spatial autoregressive panel data models and extends their analysis to the case where the spatial coefficients differ across the spatial units. It derives conditions under which the spatial coefficients are identified and develops a quasi maximum likelihood (QML) estimation...

This paper studies semiparametric versions of the classical sample selection model (Heckman (1976, 1979)) without exclusion restrictions. We extend the analysis in Honor'e and Hu (2020) by allowing for parameter heterogeneity and derive implications of this model. We also consider models that...
