Digital technology has penetrated various fields, including international trade. This study aims to analyze how barriers/openness to trade in digital services affected exports before the COVID-19 pandemic (2015-2016) and during the pandemic (2019-2020). Based on the Gravity model, exports seem...

This paper develops a structural empirical general equilibrium model of aggregate bilateral trade with path dependence of country-pair level exporter status. Such path dependence is motivated through informational costs about serving a foreign market for first-time entry of (firms in) an export...

Since firm heterogeneity has been introduced into international trade models, the importance of firm entry and exit (the extensive margin) has been highlighted. Thomas Chaney (2008) illustrates how accounting for heterogenous firms (and this extensive margin) alters the standard gravity...

This chapter discusses whether and how 'new quantitative trade models' (NQTMs) can be fruitfully applied to quantify the welfare effects of trade liberalization, thus shedding light on the trade-related effects of further European integration. On the one hand, it argues that NQTMs have indeed...

With a decrease in formal trade barriers, trade facilitation has come into prominence as a policy tool for promoting trade. In this paper, we use a gravity model to examine the relationship between bilateral trade flows and trade facilitation. We also estimate the gains in trade derived from...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting firms takes a gravity form, such that the extensive margin is also affected by...

This paper estimates the trade potential for India using the augmented gravity model and then attempts to determine the importance of trade remedies. Based on panel data, this gravity model is the first-ever attempt to estimate India's trade potential in the pre- and post- global economic and...

Gravity as both fact and theory is one of the great success stories of recent research on international trade, and has featured prominently in the policy debate over Brexit. We first review the facts, noting the overwhelming evidence that trade tends to fall with distance. We then introduce some...

Modern quantitative theories of international trade rely on the probabilistic representation of technology and the assumption of the Law of Large Numbers (LLN), which ensures that when the number of traded goods goes to infinity, trade flows can be expressed via a deterministic gravity equation...
