We show that the efficient allocation of production capacity can turn a competitive industry and downstream market into an imperfectly competitive one. Even though downstream firms have symmetric production technologies, the downstream industry structure will be symmetric only if capacity is sufficiently scarce. Otherwise it will be asymmetric, with one large “fat” capacityhoarding firm and a f...

The explosion in the creation of text corpora in recent years suggests that the opportunity may be ripe to examine quantitative techniques for their value in semantics. The present paper aims to explore one quantitative technique with an eye toward its potential value in illuminating questions of semantic theory. It is exploratory in nature, and it will not offer definite conclusions or specifi...

Background: Until now, the comparison of the rK39 strip test (RKT) and direct ag-glutination test (DAT) for detection of visceral leishmaniasis (VL) is exclusively based on either positive or negative qualification of the reaction outcome. Objective: In this study, we compared the diagnostic performance of RKT and DAT for VL both qualitatively and semi-quantitatively. Methods: For comparison ba...
