Melitz (2003) develops a seminal model in which heterogeneous firms face fixed costs of entering monopolistically competitive markets. A popular variation is that of Chaney (2008), who makes three simplifying assumptions: the underlying distribution of firm efficiencies is Pareto; a global equity fund pays agents equal shares of the profits of firms in all countries; and the measure of potential firms is exogenous. The first two assumptions simply the model, making it analytically tractable. Here, we provide a reinterpretation of the third assumption.
