Using a gravity-type explanation of international trade flows at the industry level, it is shown that the pattern of comparative advantage in terms of sectoral export/import ratios in bilateral trade can be explained by relative income and relative per capita income. Total income of a country is...

In the literature of new trade theory, most papers study the industrial location by imposing the assumption of free transportation in the agricultural sector. This paper explicitly incorporates arbitrary transport costs in both the manufacturing and the agricultural sectors into the...

Recent trade theory in the Krugman (1980) tradition predicts that countries with larger market size enjoy higher levels of total factor productivity (TFP) - and equivalently of real per capita income or welfare - as a smaller fraction of spending on inputs is affected by trade costs. However, in...

We study trade policy in a two-sector Krugman type model of trade. We conduct a general analysis allowing for three different instruments: tariffs, export taxes and production subsidies. For each instrument we consider unilateral trade policy without retaliation. When carefully disentangling the...

I modify a standard model of the home market to introduce entry barriers that create local rents. The existence of rents has relevant implications. First, the home market effect magnifies. Second, when countries are sufficiently unequal in size and rents are sufficiently large, a trade costs...
