Mainstream economic wisdom favoring cooperative free trade is challenged by a wave of disruptive trade policies. In this paper, we provide quantitative evidence concerning the economic impacts of tariffs implemented by the United States in 2018 and the subsequent retaliations by partner...

This paper shows that Cournot competition in segmented markets generate both intra-industry trade and the gravity equation. The paper also demonstrates that the gravity equation holds if and only if the market shares of an exporting country do not depend on the market where it sells. Thus, the...

One channel of welfare-improving globalization is through the increasing integration of trade. Although this is attributed to decreasing effects of distance across countries, the workhorse models of gravity fail to capture it, the so-called the missing globalization or the distance puzzle. This...

How large are the estimated welfare gains from changes in trade costs in a Melitz based trade model compared with models based on Armington and Krugman? We examine model features and scenarios that are important for policy that are unexamined in the literature. Starting with the stylized model...

This paper investigates the trade-diversion effects of regional trade agreements (RTAs), so-called “Spaghetti bowl” Phenomenon (SBP), in multilateral trade. The SBP is due to the proliferation of RTAs. Thus, I investigate the relationship between the number of RTAs concluded by a country and...

Gravity variables such as distance, adjacency, colony, free trade agreements or language are used to capture the effects of trade costs in empirical studies. By using actual data on trade costs, this paper decomposes the overall effects of such variables on trade into those through three gravity...

Agrifood standards impede trade by increasing compliance costs, but they can also enhance trade by signalling quality. This paper disentangles the trade costs and demand-enhancing effects of two important standards-technical barriers to trade, and sanitary and phytosanitary measures-on (i)...

The study aims to analyze the border effects on intra-African trade through the use of a gravity specification based on the monopolistic competition model of trade introduced by Krugman (1980). The study used CEPII data on trade flows between African countries over the period 1980-2006. We...

This paper derives the gravity equation with intermediate goods trade. We extend a standard monopolistic competition model to incorporate intermediate goods trade, and show that the gravity equation with intermediates trade is identical to the one without it except in that gross output should be...

This paper argues that large distance and border effects on trade flows in some industries might be a result of the (explicitly or tacitly) collusive division of geographic markets. A simple spatial oligopoly setting demonstrates how goods can travel shorter distances, or trade between regions...
