Réintroduction des intéractions stratégiques dans les théories du commerce international

Abstract : This thesis investigates the interest of oligopolistic competition in an economic and social dimension. The first chapter deals with the sensitivity of trade policy to competition mode. We develop a framework in which we endogenize the competition mode. Our analyses reveal that trade policy leads to the appearance of a mixed Cournot-Bertrand competition between firms.Also, the current pandemic context has led to the resurgence of export restrictions. We find that when they are unilateral, they can contribute to a better management of the pandemic.In the second chapter, we focus on the first social dimension of strategic interactions: the wage bargaining process. In OECD countries, these are conducted between workers' unions and firm managers. We find that when unions have relatively little power, trade integration leads to a deterioration of working conditions. Thus, we show that collective bargaining and monopoly union are two forms of wage bargaining that benefit neither workers nor firms. We then propose an analytical framework based on efficient bargaining that benefits both parties.The second social dimension of strategic interactions is related to antidumping policies discussed in the third chapter. Due to asymmetric information, foreign producers may present their products as high quality while expert groups tend to consider them as low quality in the importing country. As a result, consumers do not correctly perceive the quality of imported goods. We prove theoretically and empirically that this misperception of quality is at the root of dumping. We then deduce the consequences in terms of antidumping proceedings.
