We show that this result holds almost trivially for the case of a constant marginal cost of production, as mainly assumed in the literature, but it may not hold true if the marginal cost is not constant. Our result provides a simple explanation for recent empirical evidence showing exporters can be less productive than non- exporters.}, eissn = {1545-2921}, issn = {1545-2921}, issue = {2}, journal = {Economics Bulletin}, publicationstatus = {Published}, publisher = {Economics Bulletin}, url = {https://nottingham-repository.worktribe.com/output/858868}, volume = {37}, keyword = {Export, Non-constant marginal cost of production, Productivity}, year = {2017}, author = {Mukherjee, Arijit} }
