We incorporate the now standard knowledge-capital model of multinational firms in a new economic geography setting. The theoretical predictions of our model suggest that unskilled labor mobility leads to less concentration of production than skilled labor mobility does. This is in line with...

We use a model of combined endogenous growth and economic geography to study the impact of regional economic integration on the member and non-member countries of a regional union. Regional integration affects growth through interregional technology diffusion symbolized by knowledge spillovers...

The present paper is part of unpublished book that analyzes the political, social and economic collapse of the Sudan. Economic, social and distributive disparities triggered a process for the disintegration of the nation under the pretext of imposing Islamic Sharia Laws. A pronounced prominent...

We analyze how increases in the market size and in the level of international integration interact with the process of selection among firms with heterogeneous productivity levels when they are interconnected by vertical linkages. We show that larger economies do not always exhibit higher...

In this paper, we introduce a distinction between interregional and intraregional transportation costs, in a footloose capital model. This allows assessing more precisely the effects of different types of transport policies, on the spatial distribution of activities. From a normative point of...

The optimal size of an urban area is a controversial topic. We take optimal urban size to be that which minimizes net costs of city size, with larger cities first having various economies of scale (e.g. waste pickup) then later diseconomies of scale (e.g. pollution, congestion)

Germany like many other European countries subsidize commuting by granting the right to deduct commuting expenses from the income tax base. This regulation has often been changed and has regularly been under debate during the last decades. The pros (e.g. causing efficiency gains with respect to...

Substantial attention has been given to the stylized fact that workforce education level tends to increase with city size. This paper demonstrates that the positive relation between city size and skill intensity is a spurious result due to the omission of housing cost, which increases with city...

Russian Abstract: В работе рассмотрены проблемы предоставления социальных услуг в местах, которые можно отнести к «российской глубинке», а именно на периферийных...

We use a quantitative model to study the implications of European integration for welfare and migration flows across 1,318 regions. The model suggests that an increase of trade barriers to the level of 1957 reduces welfare by about 1-2 percent on average, depending on the presumed trade...
