WebNew models of international trade with heterogeneous firms (see e.g., Bernard et al., 2003; Melitz, 2003) have been quite successful explaining some patterns relating export behavior to productivity.

Firms are engaged in monopolistic competition and each faces a downward-sloping linear demand for its own variety. The linear demand generates an endogenous distribution of markups across rms that responds to the toughness of competition in a market.
