Using a matched employer-employee database for Italy we look at the spatial distribution of wages across provinces. This rich database allows us to contribute at opening the black box of agglomeration economies exploiting the micro dimension of the interaction among economic agents, both...

Following the model-based approach of Ellison and Glaeser (1997), we develop a framework to test for the link between concentration, spatial clustering and the size of plants. Concentration is an a-spatial concept of variability that can be measured with the standard locational Gini or the more...

In this paper, based on the cyclic scheduling formulation of Schilling and Pantelides [22], we propose a continuous time mixed integer linear programming (MILP) formulation for the cyclic scheduling of a mixed plant, i.e. a plant composed of batch and continuous tasks. The cycle duration is a...

We investigate and compare the spatial distribution of manufacturing activity and its determinants in Belguim, Ireland, and Portugal using comparable, exhaustive micro-level data sets.We find some similarities between Portugal and Belguim, but little for Ireland. Moreover, there is some evidence...

The location of facilities in order to provide service for customers is a well-studied problem in the operations research literature. In this paper, we establish strong connextions between fair cost allocations and linear programming relaxations for several variants of the facility location...

In this paper, we study social interactions between two populations of individuals living in a city. Agents consume land and benefit from intra- and inter-group social interactions. We show that in equilibrium segregation arises: populations get separated in distinct spatial neighborhoods. Two-...

We analyze how the interplay between urban costs, wage wedges, and trade costs may affect the interregional location of firms as well as the intraurban location, within the central business district or in a secondary employment center (SEC) of the selected region. In this way, we investigate, on...

A two-sector model of urban unemployment is developed which focuses on the formation of a secondary sector under conditions in which a demand shock in the primary sector leads to a sharp increase in unemployment. The optimal location in the secondary sector (treated as a single firm) is shown to...

We present a theoretical model of residential growth that emphasizes the path-dependent nature of urban sprawl patterns. The model is founded on the monocentric urban economic model and uses a cellular automata (CA) approach to introduce endogenous neighbourhood effects. Households are assumed...

We consider two typed of cities. In the European one the amenities are located at the city-center ( like e.g. Paris or London) whereas in the American-type city the amenites are at the city-edge (like e.g. Detroit, Los Angeles). We first show that the unemploymed reside at the vicinity of the...
