This study constructs a class of dynamic models in which optimal paths are generated by nonlinear transition functions similar to a tent map. We provide a sufficient condition under which such a transition function is a chaotic map. This characterization provides a way to construct complex...

Recent studies indicate the possibility that, in the more-than-two-country model, a coalition may block a competitive equilibrium by means of mutually advantageous transfers among its members. This study demonstrates that even the equilibrium which is to be established after a mutually...

This study investigates the effect of a country's suppression of competition in its market for nontradables. It assumes that the initial equilibrium is stationary and demonstrates that if competition is suppressed in a small country, the country's trade surplus increases in the short run. In the...

The frequency of export quotas imposed as voluntary export restraints has been increasing. This tends to create the expectation that similar export quotas will be imposed in the future, even if free trade is allowed now. The author analyzes the effect of such an expectation. He demonstrates that...
