Quality regulation attempts to ensure quality and foster competition by reducing vertical differentiation, but it may also have adverse effects on market structure. We study this trade-off in the context of pharmaceutical bioequivalence, which is the primary quality standard for generic drugs....

In this study, we assess the relative contribution of plants' self-selection and agglomeration economies to a region's productivity level. We focus on manufacturing plants by region in the Chilean food industry, which is not only a major source of employment and exports but also spatially...

We study the effects of quality regulation on market outcomes by exploiting the staggered phase-in of bioequivalence requirements for generic drugs in Chile. We estimate that the number of drugs in the market decreased by 25%, average paid prices increased by 10%, and total sales decreased by...

This paper uses plant–level data from Chile to show that an increase in sector–wide exports decreases the survival probability of exporters, but not that of non–exporters. We argue that this result can be explained by the fact that exporters and non-exporters use factors of production in...

Quality regulation attempts to ensure quality and to foster price competition by reducing vertical differentiation, but may also have unintended consequences through its effects on market structure. We study these effects in the context of pharmaceutical bioequivalence, which is the primary...
