This paper departs from previous literature by considering a mixed oligopoly with two countries each with public and private firms competing in a single market. This differs from the traditional framework of examining a single domestic market in which foreign and domestic firms compete and is motivated, in part, by international airline markets but serves to characterise many markets. The resulting equilibrium emphasises that the strategic interaction of the two public firms usually serves to reduce welfare. Thus, the usual reason to imagine a public firm in a mixed oligopoly, to enhance welfare, is lost when such firms compete in the interest of their respective countries.
Conflicts hinder international trade. Political agreements that restrain conflicts and remove sanctions may contribute positively to exporting and importing activities. In this study, we examine the effects of the Joint Comprehensive Plan of Action, commonly known as Iran Nuclear Deal, on Iran's non-oil exports. Employing a dynamic panel model, we find a significant increase in the growth rate of industry-level exports following the removal of nuclear-related sanctions, resulting from this political agreement. In particular, the exports of industries that have relatively low shares in Iran's non-oil exports grow significantly faster than industries with relatively high shares in those exports. Our findings suggest that even a short-lived political agreement could have significant positive effects on exporting activities in middle income countries.
