This paper develops a nonparametric methodology for treatment evaluation with multiple outcome periods under treatment endogeneity and missing outcomes. We use instrumental variables, pre-treatment characteristics, and short-term (or intermediate) outcomes to identify the average treatment...

This chapter surveys existing approaches to modeling labor supply and identifies important gaps in the literature that could be addressed in future research. The discussion begins with a look at recent policy reforms and labor market facts that motivate the study of labor supply. The analysis...

We consider the estimation of a semiparametric location-scale model subject to endogenous selection, in the absence of an instrument or a large support regressor. Identification relies on the independence between the covariates and selection, for arbitrarily large values of the outcome. In this...

In 2005, the Indian Government launched a conditional cash-incentive program to encourage institutional delivery. This paper studies the effects of the program on neonatal mortality using district-level household survey data. We model mortality using survival analysis, paying special attention...

Erster zu sein, ist immer vorteilhaft - diese Sichtweise wird im Kontext von Unternehmen gewöhnlich vertreten. Die akademische Literatur bestätigt diese Annahme jedoch nicht generell. Im Gegenteil, als Erster zu handeln kann auch schädlich für Unternehmen sein. Die vorliegende Studie...

Although the performance effects of multitasking were analyzed intensively in the past, little is known about the impact of the adoption time of multitasking on corporate performance. Possibly, the quantity of the reorganization is crucial and early movers experience a comparative competitive...

Social investment funds are prominent instruments in developing countries that aim at providing financial resources for social infrastructure projects to poor municipalities. In contrast to traditional, more centralised distribution mechanisms of such funds, the Bolivian Fondo de Inversión...

We replicate and reanalyse the most influential study of microcredit impacts (Pitt and Khandker, 1998). That study was celebrated for showing that microcredit reduces poverty, a much hoped-for possibility (though one not confirmed by recent randomized controlled trials). We show that the...

Pushing models to extremes can expose output biases that stem from underlying assumptions. In the case of industry standard option valuation models, long term, high volatility securities provide a stress test vehicle. For instance, in evaluating a stock with 60% volatility, industry standard...

The relationship between two alternative approaches, instrumental variables and control function procedures, for estimating the impact of endogenous treatment effects are examined. Although it is well known that the two approaches generate comparable estimates, the relationship between the...
