Equilibrium existence in Krugman’s and Bertoletti–Etro’s trade models: the general case
Economic Theory. 2025.
Slepov F., Kokovin S. G.
We revisit Krugman’s (J Int Econ 9(4):469–479, 1979.) classical trade model in its general form with several asymmetric countries and unspecified additive utility functions. We present the weakest known conditions on utilities sufficient for the existence of equilibrium. These conditions are also necessary under symmetric preferences. Using the same method for Bertoletti and Etro’s (Econ J 127(603):1217–1243, 2017.) trade model with several asymmetric countries, we establish sufficient conditions on unspecified indirect utilities for the existence of equilibrium.

This paper develops a modeling technique of “attainable profit” functions, applying it to two models of monopolistic competition. First, it revisits the Krugman's classical trade model in the most general form: several asymmetric countries and non-specified additive utility functions. We establish the weakest conditions on utilities, sufficient for the existence of equilibria. These conditions are ...
