We propose an economic model of business groups that allows for the cooperative behavior of groups of firms, where the number and size of each group is determined endogenously. In this framework, more than one configuration of groups that can arise in equilibrium: several different types of...

Do firms become more efficient after becoming exporters? Widespread empirical evidence indicates that exporting manufacturers achieve higher productivity levels than non-exporting manufacturers. Two explanations, self-selection and learning-by-exporting, are proposed in the literature, with the...

In a two-country monopolistic competition general equilibrium model, we consider two types of firms: big with higher fixed cost but lower marginal cost, and small with lower fixed cost but with high marginal cost. We prove that free trade may not always benefit the big-country and/or big firms....
