How do the trade impacts of a safeguard measure - which is statutorily designed to follow the most-favored-nation (MFN) principle - compare to explicitly discriminatory measures such as antidumping? We address this question empirically by examining the trade effects of the 2002 US safeguard on...

Instrumental Variables (IV) methods identify internally valid causal effects for individuals whose treatment status is manipulable by the instrument at hand. Inference for other populations inevitably requires some sort of homogeneity assumption. I develop a simple theoretical framework that...

Microfinance programmes provide poor people with small loans given to jointly liable self-selected groups. Follow-up loans provide incentives to repay. In an experiment we investigate the influence of those features on strategic default. Each group member invests in an individual risky project,...

We consider the problem of consistent estimation of nonlinear models with mismeasured explanatory variables, when marginal information on the true values of these variables is available. The marginal distribution of the true variables is used to identify the distribution of the measurement...

This study addresses the complexity in modeling contingent valuation surveys with true zeros and non-ignorable missing responses including “don’t knows†and protest responses. An endogenous switching tobit model is specified to simultaneously estimate the parameters of the...

The federal Earned Income Tax Credit (EITC) and the Food Stamp Program (FSP) are the largest means-tested transfer programs for low-income working parents in the United States. Together, these two programs cost nearly $50 billion per year and comprise the bulk of the social safety net for...
