This paper extends the identification results in Nevo and Rosen (2012) to nonparametric models. We derive nonparametric bounds on the average treatment effect when an imperfect instrument is available. As in Nevo and Rosen (2012), we assume that the correlation between the imperfect instrument...

We analyze identification of nonseparable models under three kinds of exogeneity assumptions weaker than full statistical independence. The first is based on quantile independence. Selection on unobservables drives deviations from full independence. We show that such deviations based on quantile...

This paper studies the effect on the risk of female victimization of the employment statuses of both partners, conditional on income and a set of sociodemo-graphic characteristics. Using cross-sectional data from the Violence Against Women (V A W) surveys for Spain in 1999, 2002, and 2006, we...

The preferences expressed in voting on nuclear reactor licenses and the risk perceptions of citizens provide insights into social costs of nuclear power and decision making in energy policy. We show analytically that these costs consist of disutility caused by unnecessary anxiety - due to...

We discuss the difficult question of measuring the effects of asymmetric information problems on resource allocation. Three problems are examined: moral hazard, adverse selection, and asymmetric learning. One theoretical conclusion, drawn by many authors, is that information problems may...

The academic circles are devoting a growing interest to delayed graduation and overeducation, but none has analyzed the joint consequences of these two phenomena. Thus, this paper studies the link between graduation not within the minimum period and overeducation, and the effects of these...

This work is aligned with the Equator Principles that are minimum criteria for granting of credit to ensure that the funded projects are developed in a socially and environmentally responsible way. The objective of this paper is to verify the relevance of social and environmental variables...

This paper provides the first available evidence on overeducation/overskilling based on AlmaLaurea data. We focus on jobs held 5 years after graduation by pre-reform graduates in 2005. Overeducation/overskilling are relatively high – at 11.4 and 8% – when compared to EU economies. Ceteris...

In this paper I revisit the interpretation of the linear instrumental variables (IV) estimand as a weighted average of conditional local average treatment effects (LATEs). I focus on a practically relevant situation in which additional covariates are required for identification while the...

This paper focuses on the bivariate probit model's identifying assumptions: joint normality of errors, instrument exogeneity, and relevance conditions. First, we develop novel sharp testable equalities that can detect all possible observable violations of the assumptions. Second, we propose an...
