This paper evaluates what type of models can account for the recent episodes of output drops in Latin America. The author develops an open economy version of the business cycle accounting methodology (Chari, Kehoe, and McGrattan, 2007) in which output fluctuations are decomposed into four sources: total factor productivity (TFP), a labor wedge, a capital wedge, and a bond wedge. The paper shows that the most promising models are the ones that induce fluctuations of TFP and the labor wedge. On the other hand, models of financial frictions that translate into a bond or capital wedge are not successful in explaining output drops in Latin America.
