I develop an assignment model of occupations with multidimensional heterogeneity in production tasks and worker skills. Tasks are distributed continuously in the skill space, whereas workers have a discrete distribution with a finite number of types. Occupations arise endogenously as bundles of...

We use 25 years of tax records for the Norwegian population to study the mobility of wealth over people's lifetimes. We find considerable wealth mobility over the life cycle. To understand the underlying mobility patterns, we group individuals with similar wealth rank histories using...

We evaluate the aggregate effects of expansions of credit supply in environments where subsistence self-employment is prevalent. We extend a standard macro development model to include unemployment risk, which becomes a key driver of selection into self-employment. The model is consistent with...

How does wealth taxation differ from capital income taxation? When the return on investment is equal across individuals, a well-known result is that the two tax systems are equivalent. Motivated by recent empirical evidence documenting persistent return heterogeneity, we revisit this question....

Selection into self-employment among the poor is dominated by subsistence concerns, which leads to high levels of unproductive self-employment in developing countries. We incorporate this view into an otherwise benchmark macro-development model by allowing for labor frictions. Standard models...

In this paper two new measures of the Colombian output gap and the real neutral interest rate are proposed. Instead of relying only on statistical filters, the proposed measures use semi-structural New-Keynesian models, adapted for a small open economy. The output gap measures presented are in...

La evidencia empírica para Colombia muestra relaciones tanto positivas como negativas entre el crecimiento del producto y el empleo, a diferencia de loencontrado en economías desarrolladas como la de los Estados Unidos. El presente trabajo usa modelos VAR para abordar explicaciones de ese...

Este artículo utiliza la metodología VAR-X estructural para explicar por qué creció el desempleo en Colombia desde niveles cercanos al 7% en 1995:I hasta 19% en el 2000:I, y por qué permaneció en niveles de dos dígitos durante la década siguiente. Se trató de una combinación...

Este trabajo utiliza la metodología VAR-X estructural para explicar por qué creció el desempleo en Colombia desde niveles cercanos a 7% en 1995:1 hasta 19% en 2000:1, y por qué permaneció en niveles de dos dígitos durante la década siguiente. Se trató de una combinación desafortunada de...
