Omitted variable bias (OVB) of OLS estimators is a serious and ubiquitous problem in social science research. Often researchers use the direction of the bias in substantive arguments or to motivate estimation methods to deal with the bias. This paper offers a geometric interpretation of OVB that...

In this paper I discuss three issues related to bias of OLS estimators in a general multivariate setting. First, I discuss the bias that arises from omitting relevant variables. I offer a geometric interpretation of such bias and derive sufficient conditions in terms of sign restrictions that...

Kalyal Sanayal's work on postcolonial capitalism has been influential in many strands of critical social theory. In this brief note, I investigate three key components of his argument and find them wanting. In particular, I show that the evolution of land ownership in India does not support the...
