Much of the variation in international trade volume is driven by firms’ extensive margin decision to participate in export markets. To understand this decision and predict the sensitivity of export flows to changes in trade costs, we estimate a standard model of firms’ export participation. In choosing whether to export, firms weigh the fixed costs of exporting against the forecasted profits fr...

Serratia marcescens secretes several proteins, such as the lipase LipA, the metalloprotease PrtA, and the heme-binding protein HasA, which is required for heme acquisition, through two N-terminal signal peptide-independent systems that are classified as bacterial ATP-binding cassette (ABC) exporters. One is the ABC exporter for HasA, consisting of the ABC protein HasD, the membrane fusion prote...

This paper investigates the link between exporting and importing activities and firm performance using a rich dataset on Egyptian and Moroccan firms. We test the export premium, self-selection and learning-by-exporting hypotheses using a number of firm characteristics. Our analysis also includes importing activities as a source of learning and considers their effects on productivity changes. A ...

AcrAB exports some beta-lactam antibiotics in the periplasm out of cells via an outer-membrane channel, TolC. It has been reported that eight drug transporters in Escherichia coli cooperate with TolC. In this study, the roles of the drug exporters of E. coli in beta-lactam resistance were examined. We found that five of five resistance-nodulation-cell division-type drug exporters confer beta-la...

We explore the effects of trade costs on markups by building a new model consistent with three stylized facts: exporters charge higher markups, markups increase when starting to export, and domestic and foreign sales are negatively correlated, which suggests decreasing returns. We calibrate the model to Chilean data, and simulate reductions in trade costs. Most markups increase along the intens...

Purpose – This study aims to empirically investigate the impacts of quota elimination on world clothing trade. Design/methodology/approach Multivariate analysis of variance (MANOVA) was undertaken based on trade statistics of 51 clothing exporters from 2000 to 2009 provided by the World Trade Organization (WTO). Findings – First, exporters’ performances in response to quota elimination overall ...

A firm’s competitive advantage can be created through developing and maintaining long-term effective relationships with customers. To achieve successful long-term business relationships, partners need to develop and maintain a high degree of relationship quality. Although the importance and benefits of high quality relationships are widely recognised, little research has been undertaken to exam...
