We provide a simple theoretical foundation, based on the theory of Markov chains, for the objective empirical procedure for journal ranking devised by Liebowitz and Palmer.An elementary characterization is derived that substantially clarifies the meaning, scope and underlying intuition of the...

From data in the form of a two-way contingency table “Regions _ Sectors”, the concepts of specialization and concentration, built from the analysis of conditional distributions or profiles, is based on discrepancies among distributions: between profiles and a uniform distribution for...

We show that how technological innovations and migration costs interact to shape the space-economy. Regardless of the level of transport costs, rising labor productivity fosters the agglomeration of activities, whereas falling transport costs do not affect the location of activities. When labor...

We study how political boundaries and tax competition among jurisdictions interact with the labor and land markets to determine the economic structure and performance of metropolitan areas. Contrary to general belief, institutional fragmentation and cross-border commuting need not be...

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-...

In this study, we explore the role of export spillovers on the capacity of French firms to conquer Asian markets. We confirm, in the context of France, previous results emphasizing the positive impact of surrounding exporters on the probability that a firm starts exporting a given product to a...

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a...

In this study, we explore how the intensity of foreign export spillovers in China varies depending on the difficulty of entry on export markets. We rely on different proxies to define what a "difficult" country is and we find that the presence of surrounding foreign exporting firms helps...

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...
