This paper uses the control function to develop a framework for testing for selection bias. The idea behind our framework is if the usual assumptions hold for matching or IV estimators, the control function identifies the presence and magnitude of potential selection bias. Averaging this...

In Canada, a policy aiming at helping single parents on social assistance become self-reliant was implemented on an experimental basis. The Self-Sufficiency Entry Effects Demonstration randomly selected a sample of 4,134 single parents who had applied for welfare between January 1994 and March...

This paper considers the problem of making inferences about the effects of a program on multiple outcomes when the assignment of treatment status is imperfectly randomized. By imperfect randomization we mean that treatment status is reassigned after an initial randomization on the basis of...

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...

This paper offers some new directions in the analysis of nonparamertric models with exogenous treatment assignment. The nonparametric approach opens the door to the examination of potentially different distributed outcomes. When combined with cross-validation, it also identifies potentially...

This paper considers the problem of making inferences about the effects of a program on multiple outcomes when the assignment of treatment status is imperfectly randomized. By imperfect randomization we mean that treatment status is reassigned after an initial randomization on the basis of...

This paper presents a World Bank led and Russia trust fund financed work program to measure financial capability and the effectiveness of financial education in low and middle income countries. The two activities and their staging have been motivated by the lessons of high-income countries with...

Many emerging markets have undertaken significant financial sector reforms especially in their banking sectors that have been quite critical for both financial development and real economic activity. In this paper, we investigate the success of banking reforms in India where significant banking...

This study investigates the long-term effects of initial labor market conditions by comparing cohorts who graduated from college before, during, and after the 1997-1998 Asian financial crisis in South Korea. We measure the overall welfare effect by examining their labor market activities, family...
