Many factors innuence the performance of a learned classiier. In this paper we study diier-ent methods of measuring performance based on a uniied set of cost models and the eeects of training class distribution with respect to these models. Observations from these eeects help us devise a distributed multi-classiier meta-learning approach to learn in domains with skewed class distributions, non-...

Subordination is designed to provide credit risk protection for senior CMBS tranches by allocating the initial credit losses to the more junior tranches. Subordination level should in theory reflect the underlying credit risk of the CMBS pool. In this paper, we test the hypothesis that subordination is purely about credit risk as intended. We find a very weak relation between subordination leve...

The paper develops a simple theoretical framework of financial discipline during the stabilization of a transition economy, from which it derives an empirical measure to assess whether the banking sector has started to act as a source of financial discipline, or just as a temporary buffer for enterprise losses. The model suggests that in the presence of active bank monitoring the correlation be...

How much did the contraction in the supply of credit to households contribute to the decline in employment during the Great Recession? To answer this question I provide new estimates of: (1) the elasticity of employment with respect to household credit; and (2) the size of the supply shock to household credit. I exploit a county’s exposure to the collapse of a large and previously healthy lende...
