I review recent work in the statistics literature on instrumental variables methods from an econometrics perspective. I discuss some of the older, economic, applications including supply and demand models and relate them to the recent applications in settings of randomized experiments with...

In this chapter, we present econometric and statistical methods for analyzing randomized experiments. For basic experiments, we stress randomization-based inference as opposed to sampling-based inference. In randomization-based inference, uncertainty in estimates arises naturally from the random...

Abstract We derive a class of design-based estimators for the average treatment effect that are unbiased whenever the treatment assignment process is known. We generalize these estimators to include unbiased covariate adjustment using any model for outcomes that the analyst chooses. We then...

We study the long-run impacts of health insurance promotion in Northern Ghana. We randomly provide three overlapping interventions to promote enrollment: subsidy, information campaign, and convenient sign-up option, with follow-up surveys seven months and three years after the initial...

When estimating the extent of e.g. excess use of public benefits one traditionally uses direct monitoring. Such direct estimates are afflicted with an intrinsic negative bias since you only count what you find. This paper presents and assesses an alternative intuitive, yet relatively unexplored,...

Results in behavioral economics suggest that material incentives can crowd out effort, if agents are mission-oriented rather than self-interested. We test this prediction on a sample of nonprofit organizations in Sweden. Swedish nonprofit organizations receive tax funds annually to promote...
