This paper starts from a review of RCT studies in development economics, and documents many studies largely ignore attrition once attrition rates are found balanced between treatment arms. The paper analyzes the implications of attrition for the internal and external validity of the results of a...

we demonstrate that in this extended setup Probit estimation on panel data sets does not pose a specific problem. The …Mundlak (1978) proposed the addition of time averages to the usual panel equation in order to remove the fixed effects …

units are available over time. We lay out the theory underlying SDID, both when there is a single treatment adoption date … and when adoption is staggered over time, and discuss estimation and inference in each of these cases. We introduce the … sdid command which implements these methods in Stata, and provide a number of examples of use, discussing estimation …

We propose a specification test for a wide range of parametric models for the conditional distribution function of an outcome variable given a vector of covariates. The test is based on the Cramer-von Mises distance between an unrestricted estimate of the joint distribution function of the data,...

We characterize the bias of propensity score based estimators of common average treatment effect parameters in the case of selection on unobservables. We then propose a new minimum biased estimator of the average treatment effect. We assess the finite sample performance of our estimator using...

Currently there is little practical advice on which treatment effect estimator to use when trying to adjust for observable differences. A recent suggestion is to compare the performance of estimators in simulations that somehow mimic the empirical context. Two ways to run such 'empirical Monte...

The identification of average causal effects of a treatment in observational studies is typically based either on the unconfoundedness assumption or on the availability of an instrument. When available, instruments may also be used to test for the unconfoundedness assumption (exogeneity of the...

A growing literature uses repeated cross-section surveys to derive 'synthetic panel' data estimates of poverty dynamics … synthetic panel estimates relative to benchmarks based on estimates derived from genuine household panel data, employing high …. Overall, we are more agnostic about the validity of the synthetic panel approach applied to these two rich countries than are …

An emerging literature on international activities of heterogeneous firms documents that exporting firms are more productive than firms that only sell on the national market. This positive exporter productivity premium shows up in a large number of empirical studies after controlling for...
