Career

Andrews was the Silverman (1968) Family Career Assistant Professor and an associate professor at the Massachusetts Institute of Technology from 2016 to 2018, when he joined the faculty at Harvard. In 2023, he returned to MIT as a professor.

Much of Andrew's research is in the field of

econometrics Econometrics is an application of statistical methods to economic data in order to give empirical content to economic relationships. M. Hashem Pesaran (1987). "Econometrics", '' The New Palgrave: A Dictionary of Economics'', v. 2, p. 8 p. 8 ...

instrumental variables In statistics, econometrics, epidemiology and related disciplines, the method of instrumental variables (IV) is used to estimate causal relationships when controlled experiments are not feasible or when a treatment is not successfully delivered to ...

. Instrumental variables are variables that affect one part of a co-determined system without affecting another part of the same system. For this type of estimation to be effective, an instrumental variable must satisfy the relevance condition, that is, it must affect one part of the system, and it must satisfy the exclusion restriction, that is, it must not affect the other part of the system. Andrews' research concerns situations in which either the relevance condition or the exclusion restriction hold only weakly. Together with Mikusheva, he has studied the properties of weak instruments in estimating
