This paper investigates how trade openness affects wage inequality of trading countries, both within and between them. Specifically, based on the theoretical literature on monopolistic competition between two asymmetric countries, we derive a new framework under the assumption of endogenous...

In this paper, we theoretically investigate the role of technology level in Global Value Chain (GVC) formation from two aspects: position and participation volume. We develop a simple two-country model where countries are heterogeneous with respect to their technology level and labor force. In...

This paper investigates the optimal dynamic paths of trade protection imposed on infant industries during the process of joining a free trade agreement. The framework is based on the dynamic learning-by-doing model developed in Melitz (2005), where industries are experiencing dynamic...

This paper proposes a framework to derive the optimal dynamic path of tariffs to protect infant industries when a country initiates a process to join the World Trade Organization (WTO). The framework is based on the model of Melitz (2005) in which externalities associated with dynamic...

Elliott and Mler (2007) (EM) provides a method to construct a confidence set for the structural break date by inverting a locally best test statistic. Previous studies show that the EM method produces a set with an accurate coverage ratio even for a small break, however, the set is often overly...
