This study develops and estimates a model of the naturalization process in the US. The model is based on both the characteristics of immigrants and features of their countries of origin. The empirical analysis is based on the 2000 US Census...

The "common effect" model in program evaluation assumes that all treated individuals have the same impact from a program. Our paper contributes to the recent literature that tests and goes beyond the common effect model by investigating impact heterogeneity using data from the experimental...

This paper explores how cross-sectional data can be exploited jointly with longitudinal data,in order to increase estimation efficiency while properly tackling the potential bias due tounobserved individual characteristics. We propose an innovative procedure and we show itsimplementation by...

The Polish tax and benefit system is presented in the context of a recently developedmicrosimulation model, SIMPL. The model allows simulating direct taxes, social contributionsand public benefits in Poland for the years 2003 and 2005...>br>

This paper examines the effects of the Working Families´ Tax Credit (WFTC) on couples inBritain. We develop a simple model of household decisions which explicitly accounts for therole played by the tax and benefit system. Its main implications are then tested using paneldata from the British...

One important concern of governments in developing countries is on how to phase-out largesafety nets programs. This paper evaluates the short run effects of one possible exit strategy,programs that promote self-employment, in Argentina. We provide evidence that a smallfraction of beneficiaries...

Most of the literature on the evaluation of training programs focuses on the effect ofparticipation on a particular outcome (e.g. earnings). The “treatment” is generally representedby a binary variable equal to one if participation in the program occurs, and equal to zero if noparticipation...
