In this paper we develop a simple model of the signaling value of the GED credential. The model illustrates necessary assumptions for a difference-in-difference estimator, which uses a change in the GED passing standard, to yield unbiased estimates of the signaling value of the GED for marginal...

Using the Canadian General Social Survey we compute returns to post-secondary education relative to high-school. Unlike previous research using Canadian data, our dataset allows us to control for ability selection into higher education. We find strong evidence of positive ability selection into...

This paper investigates the earnings effects of training in the Portuguese labour market. We use the Portuguese Labour Force Survey to classify training according to multiple criteria, including providing institution, purpose, duration, and content of the training activity. First, we establish...

I study a model where Information Technology, while typically increasing overall inequality, is likely to harm some people at intermediate and high levels of the distribution of income but to benefit people at the bottom. Within a given occupation it may harm some workers while benefitting...

Standardized testing is a controversial subject, particularly in British Columbia. However, as this Commentary argues, standardized test results can be a valuable resource as long as they are placed into the proper context. It is no surprise that students who have parents with more education or...

Este trabajo de investigación analiza los procesos de reforma curricular de Perú, Colombia, Chile y Argentina en los años noventa, centrando la atención en los mecanismos de elaboración e implementación curricular, así como en la evaluación de los resultados de aprendizaje y en el uso de...

El presente Documento de Trabajo contiene los resultados de la administración de diversas escalas de actitudes a estudiantes de cuarto y sexto grado de primaria y cuarto grado de secundaria durante la evaluación nacional del rendimiento estudiantil organizada por la Unidad de Medición de la...

This paper finds the effect of having friends of a similar race and who are involved in similar activities. It explores data which allows a peer group to be defined openly through self nominations. Using a strategy that corrects for the endogeneity of peer effects by instrumenting using...

We propose finite sample tests and confidence sets for models with unobserved and generated regressors as well as various models estimated by instrumental variables methods. The validity of the procedures is unaffected by the presence of identification problems or "weak instruments", so no...

We develop a tractable general theory for the study of the economic and demographic impact of epidemics. In particular, we analytically characterise the short and medium term consequences of epidemics for population size, age pyramid, economic performance and income distribution. To this end, we...
