In this note we study the implications on a bivariate normal Roy Model of two sets of monotonicity hypotheses proposed recently by Manski and Pepper (2000). In that simple context, we show that these hypotheses imply strong restrictions on the correlations structure between the decision and the...

This paper considers the identification and estimation of an extension of Roy’s model (1951) of sectoral choice, which includes a non-pecuniary component in the selection equation and allows for uncertainty on potential earnings. We focus on the identification of the non-pecuniary component,...

How did skilled-biased technological change affect wage inequality, particularly between men and women? To answer that question this paper constructs a task-based Roy model in which workers possess a bundle of basic skills, and occupations are characterized as a bundle of basic tasks. The model...

Job polarisation has had strong effects on US workers' relative wages, according to research by Michael Boehm. His study examines whether the decline in manufacturing and clerical jobs has been responsible for the lagging wages of middle-skill workers in the United States. Comparing the...

An emerging literature argues that changes in the allocation of workplace "tasks" between capital and labor, and between domestic and foreign workers, has altered the structure of labor demand in industrialized countries and fostered employment polarization – that is, rising employment in the...

Over the last two decades, earnings in the United States increased at the top and at the bottom of the wage distribution but not in the middle - the intensely debated middle class squeeze. At the same time there was a substantial decline of employment in middle-skill production and clerical...

El presente documento tiene por objetivo caracterizar la informalidad en Colombia. Se discuten las diferentes alternativas que se han considerado para definir y medir la informalidad y, con base en criterios técnicos, se emplea la definición asociada a la no afiliación a seguridad social...

The aim of this paper is to provide fresh empirical evidence on the mechanisms through which wage inequality affects worker satisfaction.Theoretically, the wages of others may affect workers' utility for two main reasons: Workers may derive well-being from their social status (the comparison...
