The incomplete nature of contracts governing international transactions limits the extent to which the production process can be fragmented across borders. In a dynamic, general-equilibrium Ricardian model of North-South trade, the completeness of international contracts is shown to lead to the...

This chapter provides an overview of the first two decades of the Global Trade Analysis Project (GTAP) an effort to support a standardized database and computable general equilibrium (CGE) modeling platform for international economic analysis. It characterizes GTAP in four different dimensions:...

World trade evolves at two margins. Where a bilateral trading relationship already exists it may increase through time (intensive margin). But trade may also increase if a trading bilateral relationship is newly established between countries that have not traded with each other in the past...

This paper provides an economic analysis of the trade conflict between the US and China, providing an overview of the tariff increases, a discussion of the background of the trade conflict, and an analysis of the economic effects of the trade conflict, based both on empirics (ex post analysis)...

This paper investigates the positive international spillover effects of non-discriminatory product regulations, such as quality standards. We incorporate regulations into a multi-country general equilibrium framework with firm heterogeneity and variable markups. We model regulations as a...

This paper aims to examine the changes in global value chains (GVCs) in the years 2020-2022 (times of the COVID-19 pandemic) compared to 2019 (last year before the pandemic). GVCs are illustrated by diagrams based on the statistics on international trade measured by value-added exports and...

We develop a structural framework that allows us to quantify the evolution of aggregate bilateral trade costs and markups over time. With minimal assumptions, we can disentangle aggregate markup and trade cost changes from observed changes in trade flows. We apply our method to trade data...

This paper investigates the role of firm heterogeneity in environmentally extended new trade models, contrasting Eaton-Kortum and Melitz models to Armington and Krugman models. We show that when emissions per sales are constant across firms -- a standard assumption in the literature -- all four...
