Over the last 20 years the trade literature repeatedly documented the trade-reducing effects of inter- and intra-national borders. Thereby, the puzzling size and persistence of observed border effects from the beginning raised doubts on the role of underlying political borders. However, when...

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

In this paper, we estimate a gravity equation properly accounting for omitted exporter and importer's overall trade resistance, through country yearly dummies for exporter and importer countries. We find that the omission of time varying multilateral trade resistance terms in the estimation of a...

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 applies the augmented gravity model to study the changing pattern of Ghana's bilateral trade flows and to extract practical trade policy implications. Economic classification dummies are included in the gravity equation to characterize the peculiarity of South-South and North-South...

This paper identifies a "border" effect in the absence of a border. The finding that trade between East- and West-Japan is 23.1 to 51.3 percent lower than trade within both country parts, is established despite the absence of an obvious east-west division due to historical borders, cultural...

The proposed Trans-Pacific Partnership (TPP) is a free trade agreement among 12 Pacific Rim countries whose joint gross domestic products (GDPs) account for 36 percent of world GDP and whose mutual trade accounts for approximately 24 percent of world trade. As for most proposed free trade...

Do economic sanctions affect internal support of sanctioned countries’ governments? To answer this question, we focus on the sanctions imposed on Russia in 2014 and identify their effect on voting behavior in both presidential and parliamentary elections. On the economic side, the sanctions...
