Este artigo procurou traçar um perfil da sociedade brasileira em idade sexualmente ativa com respeito ao conhecimento adquirido sobre HIV/AIDS. Neste sentido procurou-se identificar como fatores socioeconômicos, demográficos, comportamentais e de localização, influenciam no nível de...

The key contribution of this paper is to show how to incorporate more information into the empirical strategy in order to avoid the need of valid instruments, which are difficult to find in many instances. I use information on price elasticity to propose a methodology that is able to determine...

This paper investigates the consequences of ignoring price heterogeneity on the estimation of markups using micro-data. I show that ignoring output price heterogeneity yields markup estimates severely biased towards one regardless of competitiveness levels. To do so, I set up an econometric...

This paper develops a methodology to uncover consumer preferences from a discrete-choice demand model of product differentiation using plant-level data. When prices and quantities are observed, the appropriate strategy for estimating such model is well developed. However, most plant-level data...

Markups, returns to scale and productivity can be uncovered from regressing output on inputs. However, econometric identification of theses parameters may be problematic due the simultaneity problem. A common solution is the IV method. However, usual instruments are only weakly correlated to the...
