We present a model where long-run growth and industrial location are jointly endogenous by introducing Romerian product innovation growth into Krugman's core-periphery model. We focus on stability, showing that growth is a powerful centripetal force, but that knowledge spillovers are a powerful...

This paper analyses industrial policy in a high wage open economy hosting an agglomeration consisting of vertically linked upstream and downstream firms. Optimal policy towards upstream and downstream industries differ radically in this setting. However the restriction that the agglomeration...

Using a simple monopoly model, this note analyses the incentives of a vaccine producer. Because a vaccine tends to eradicate the disease for wich it is intended, it also tends to destroy its own market. This means that monopolistic producers may be tempted, in a socially non-optimal way, to...

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...

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...

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 e.g. the standard Melitz model, since it predicts that...

This paper first presents stylized evidence showing how the date of the adoption of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We then present a theoretical model with countries of different size, trade costs, and firms competing...

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...
