In this study, we argue that the conventional intra-industry trade (IIT) index does not address the quality issue directly and propose a methodology to make full use of unit-price gap information to deduce quality differences between simultaneously exported and imported products. By applying...

This paper starts out from the observation that the export shares of firms (export to sales ratio) vary greatly among firms, and tend to be systematically related to the firms' capital labour ratios. This observation cannot be explained by the standard heterogeneous firms and trade model by...

In this paper we build an economic geography model where firms sell product varieties with heterogenous demands. We show that firms selling the products with higher demands select to set up their plants in larger countries. Larger countries do not only get better access to more varieties but...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

The present paper focuses on sorting as a mechanism behind the well-established fact that there is a central region productivity premium. Using a model of heterogeneous firms that can move between regions, Baldwin and Okubo (2006) show how more productive firms sort themselves to the large core...

This paper compares two policies: trade cost reduction and firm relocation cost reduction using a three-country version of a heterogeneous-firms economic geography model, where the three countries have different market (population) size. We show how the effects of the two policies differ, in...

This paper compares two policies: trade cost reduction and firm relocation cost reduction using a three-country version of a heterogeneous-firms geography and trade model, where the three countries have different market (population) sizes. We show how the effects of the two policies differ, in...

Regional differences in banking integration determined how Japan s Great Recession after 1990 spread across the country. We explain these differences with the emergence of silk reeling as the main export industry after Japan s opening to trade in the 19th century. The silk-exporting prefectures...

This paper uses a monopolistic competitive framework with many sectors to study the impact of trade liberalization on local and global emissions. We focus on the interplay of the pollution haven effect and the home market effect and show how a large-market advantage can counterbalance a high...

This paper introduces scale economies or density economies in transportation in a trade and geography model with heterogeneous firms. This relatively small change to the standard model produces a new pattern of spatial sorting among firms. Contrary to the existing literature, our model produces...
