This paper analyses the effect of allowing for a more general production structure in the core-periphery (CP) model. Two special cases of fully horizontally- and vertically-integrated firms are treated. The case of horizontally-integrated firms is a counter-example to the strong agglomeration...

Tax competition between two countries is considered in a trade-and-location setting with differentiated products and monopolistic competition. There are two groups of workers, mobile ones and immobile ones. Taxes are used for producing a public good. It is shown that an equilibrium with mobile...

This Paper analyses the interaction of economic integration and some typical regional policies in a new economic geography model with three regions of different size. The policies analysed are when the government controls the location of industry through location permits, infrastructure...

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...

The standard race-to-the-bottom result is curious in one respect. If a nation wants to attract foreign capital, providing the optimal level of public amenities (and thus charging the optimal tax rate) would seem optimal. This conjecture fails in the standard tax competition model since foreign...

Using a simple monopoly model, this note analyses the incentives of a vaccine producer. Because a vaccine tends to eradicate the disease for which 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...
