This paper investigates the behavior of Korean trade flows during the last three decades and presents estimates of aggregate export and import equations. In particular, it considers different choices for scale and price variables and assesses the relative merits of these alternative...

In early 2020, the disease Covid-19 caused a drastic lockdown of the Chinese economy. We use a quantitative trade model with input-output linkages to gauge the effects of this adverse supply shock in China on the global economy through international trade and global value chains (GVCs). We find...

This paper finds that the food problem can lead to large gains from lowering trade costs for poor countries. To quantify these potential gains from trade, I extend the Eaton-Kortum trade model to include a tradable agriculture sector, minimum consumption and home production technology of...

The gravity model is a workhorse tool that has been widely used in international trade. However, one empirical question that frequently arises is related to the conceptualization and measurement of distance. To overcome this limitation, our study proposes an index of distance based on...

Middle Eastern and North African (MENA) countries stand out in international comparisons of de jure obstacles to female employment and entrepreneurship. These obstacles manifest themselves in low rates of female labor participation, entrepreneurship, and ownership. Recent research suggests a...

We propose a structural alternative to the Economic Complexity Index (ECI, Hidalgo and Hausmann 2009; Hausmann et al. 2011) that ranks countries by their complexity. This ranking is tied to comparative advantages. Hence, it reveals information different from GDP per capita on the deep underlying...

The relative rise of wages for high-skilled workers over the last three decades has been the subject of intense academic and popular scrutiny. This paper develops a new methodology for decomposing wage changes into three sources: outsourcing, biased technological change, and total biased...

In order to assess the effects of increased outsourcing on the relative demand for skilled and unskilled labor, it is crucial to understand whether outsourcing is a complement or a substitute for each kind of labor. Using the traditionally employed log-log framework, Amiti and Wei (2006) find...

The article considers the theoretical and methodological approaches to global value chains when measuring international trade. Global trends in the modern development of international trade are analysed, and the main challenges of international trade policy for Ukraine are characterised. It is...

Larger Indian firms selling inputs to other firms tend to have more customers, tend to be used more intensively by their customers, and tend to have larger customers. Motivated by these regularities, I propose a novel empirical model of trade featuring endogenous formation of input-output...
