Monotonicity and the Roy Model

The Empirical Content of the Roy Model

The Roy model discussed here can be applied to situations where we have individuals selecting into one of two or more sectors. Examples would include, the education level choice (High School vs College) and labor participation choice (join the work force or not, especially for in the context of female labor supply). We shall examine the labor participation choice and applications of the Roy mod...

Nonparametric Identi cation and Estimation of the Extended Roy Model

This paper proposes a new identi cation and estimation method for the extended Roy model, in which the agents maximize their utility rather than just outcome. The identi cation results substantially relax conventional functional form restrictions. No functional form restriction is imposed on the distribution of the potential outcomes. The utility functions are allowed to be nonlinear so that it...

Non-parametric Identication and Testable Implications of the Roy Model

This paper studies non-parametric identi…cation and the testable implications of the Roy Model. Results in the literature are generalized in three directions. First, my model allows fully general functions that characterize the income of di¤erent occupations. Second, identi…cation is obtained using strictly weaker exclusion restrictions. For example, the model with additive heterogeneity is non...

Roy 27_7

Multiple genetic alterations are common in cancers including those of the breast. The mechanisms leading to these alterations such as point mutations, gene amplifications, deletions and replication error are often associated with frequent and consistent loss of heterozygosity (LOH) or microsatellite instability (MSI). Several cytological and molecular studies have shown high frequency loss of g...
