This paper posits a new approach to the ?wage equation? of the New Economic Geography (NEG). On one side, it is shown that the NEG provides a spatial explanation of marginal costs, instead of wages. On the other side, and focusing on the statistical properties of the data, it is explained why...

This paper looks inside the firm and investigates how trade alters the matching of worker-specific abilities and task-specific requirements. The outcome of this matching depends on how firms organize their recruitment process and how much they invest into the screening of applicants. In the open...

We use unique plant-level data to study the link between the local availability of services and the decision of manufacturing firms to source materials from abroad. To guide our empirical analysis we develop a monopolistic-competition model of the materials sourcing decisions of heterogeneous...

We propose a theory that emphasizes the role of managers for the production and allocation of human capital in firms. Managers invest time to train junior employees, and acquire information about the juniors' abilities that is valuable for job assignments. This dual role of managers matters...

The field of New Economic Geography (NEG) aims at explaining agglomeration based on increasing returns, monopolistic competition and international factor mobility. Deviating from existing approaches, this paper constructs a theoretical model based on capital market frictions. Firms compete...

The paper asks whether subsidies aiming to redistribute economic activity across regions can be justified with the welfare argument. Moreover, different tax systems are compared with respect to the size of the subsidy needed for achieving a certain spatial distribution of economic activity, and...

Using a simplified NEG model, we investigates the relation between labor diversity and agglomeration. In the theoretical part, we assume the following two-region model. Homogenous consumption goods are produced using a constant returns technology with homogenous capital and heterogenous workers....

New economic geography focuses on the impact of falling transport costs on the spatial distribution of activities. However, it disregards the role of technological innovations, which are central to modern economic growth, as well as the role of migration costs, which are a strong impediment to...

Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country s share in world endowments and its share in producing firms: the so called home market effect (HME). We show that the single-sector Melitz (2003) model...

This paper studies the social desirability of agglomeration and the efficiency arguments for regional policy in a simple, analytically solvable ‘new economic geography’ model with two trade integrating regions. The location pattern emerging as market equilibrium is ?-shaped, featuring...
