This paper introduces a market size dependent firm entry cost into the Melitz (2003) model. This is a relatively small generalisation, which preserves the analytical solvability of the model. Nevertheless, our model yields several new results that are in line with data. First, the average...

This paper analyses the effect on agglomeration tendencies of allowing firms to become multi-region firms in a standard model of trade and location. More specifically, we introduce horizontal and vertical multi-region firms into the core-periphery (CP) model developed by Krugman (1991). The...

FDI has received surprisingly little attention in theoretical and empirical work on openness and growth. This paper presents a theoretical growth model where MNCs directly affect the endogenous growth rate via technological spillovers. This is novel since other endogenous growth models with...

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 purpose of this study is to test for the effects of trade promotion via the foreign service. We develop a Melitz-based model where firms are heterogeneous with respect to productivity and must pay a beachhead cost to enter a foreign market, which can be reduced by government spending on...

This paper modifies the heterogenous firms and trade model by Melitz (2003) by explicitly modelling the entry cost of a firm in a new market as a function of market size. This leads to several new predictions compared to the standard model: The productivity of non exporters and exporters depends...

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...

The purpose of this study is to test for the effects of trade promotion via the foreign service. We develop a Melitz-based model where firms are heterogeneous with respect to productivity and must pay a beachhead cost to enter a foreign market, which can be reduced by government spending on...

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...

This paper develops a theoretical model of trade and environmental emissions with heterogeneous firms, where firms make abatement investments and thereby affect their level of emissions. We show that investments in abatement are positively related to firm productivity and firm exports, while...
