This paper reviews some of the most popular policy evaluation methods in empirical microeconomics: social experiments, natural experiments, matching, instrumental variables, discontinuity design, and control functions. It discusses identification of traditionally used average parameters and more...

In-work transfers are often seen as a good trade-off between redistribution and efficiency, as they alleviate poverty among low-wage households while increasing financial incentives to work. The present study explores the consequences of extending these transfers in Ireland, where support for...

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 study estimates a Keynesian simultaneous, dynamic macroeconometric model to investigate the impact of remittances on key macro variables such as consumption, investment, imports and income in Turkey. The estimated impact and dynamic multipliers indicate that impact of remittances on...

In this paper we evaluate the premise from the recent literature on Monte Carlo studies that an empirically motivated simulation exercise is informative about the actual ranking of various estimators when applied to a particular problem. We consider two alternative designs and provide an...

Exchange market pressure (EMP) measures the pressure on a currencyto depreciate. It adds to the actual depreciation a weightedcombination of policy instruments used to ward off depreciation,such as interest rates and foreign exchange interventions, where theweights are their effectiveness. The...

This paper contributes to the literature on specific deterrence by addressing the issue of selecting adolescents into adult and juvenile law systems. In Germany, different from the U.S. and most other countries, turning a critical cutoff age does not cause a sharp discontinuity from juvenile to...

In this paper we assess the impact of a Minimum Income Scheme (MIS) which has been operating in the Basque Country, one of Spain's 17 regions, for more than twenty years. In particular, we test whether the policy delays entry into employment for recipients. In addition, we test the efficacy of...

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...

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...
