This paper considers tests of the parameter of an endogenous variable in an instrumental variables regression model. The focus is on one-sided conditional t-tests. Theoretical and numerical work shows that the conditional ...

This paper applies classical exponential-family statistical theory to develop a unifying framework for testing structural parameters in the simultaneous equations model under the assumption of normal errors with known ...

As Nelson and Startz [Nelson, C.R., Startz, R., 1990a. The distribution of the instrumental variable estimator and its t ratio when the instrument is a poor one. Journal of Business 63, S125-S140; Nelson, C.R., Startz, R., ...

It is well-known that size adjustments based on bootstrapping the t-statistic perform poorly when instruments are weakly correlated with the endogenous explanatory variable. In this paper, we provide a theoretical proof ...

Research on acquisitions falls prey to specific challenges to causal inference that need closer attention from merger and acquisition researchers. In this chapter, I focus on the general challenges to causal inference with ...

We estimate the effect of prison labor programs on recidivism using a nationwide census-based dataset of all prison inmates released in 2010 in Chile and tracked for two years after release. Because participation in ...
