We suggest that bilateral gravity equations augmented by ad hoc measures of absolute supply-side country differences are misspecified. Building on Haveman and Hummels (2004), we develop and test an alternative specification rooted in incomplete specialization that views bilateral gravity...

In this paper we analyze the evolution of firm financial efficiency in the Czech Repub-lic. Using a large panel of more than 400,000 Czech firm/years we study whether firms fully utilize their resources, how firm financial efficiency evolves over time, and how firm financial efficiency is...

Within a higher-dimensional incomplete specialization Heckscher-Ohlin framework, we first develop a gravity model that views bilateral gravity equations as statistical relationships constrained on countries’ multilateral specialization patterns. Second, we test our model empirically by using a...

By combining and extending the previous literature, we develop and test a gravity specification that views bilateral gravity equations rooted in a Heckscher-Ohlin framework as statistical relationships constrained on countries’ multilateral specialization patterns. According to our results,...

We employ a large panel data set and analyze efficiency in the Czech firms during 1998-2007. We investigate how their efficiency evolves over time and how it is affected by ownership structures. Methodologically we employ a panel version of a stochastic production frontier model. We distinguish...
