Moreover, he is a member of the scientific advisory boards of the Central Bank Research Association and the Centre d'Etudes Prospectives et d'Informations Internationales (CEPII), among others.
[1] Reviewing the literature on economic geography, Ottaviano and Diego Puga reconcile the conclusions of Spence (1976) and Dixit and Stiglitz (1977): stronger competition in local product and factor markets causes spatial dispersion, though firms tend to locate close to large markets in order to take advantage of increasing returns to scale and keep trade costs low, which in turn creates pecuniary externalities fostering economic agglomeration.
[4] In that context, Ottaviano and Rikard Forslid developed an extension of Krugman's classical core-periphery model through the introduction of heterogeneity in workers' skills and mobility.
[8] They similarly showed how growth, FDI, and industrial concentration are mediated through transaction costs and R&D spillovers, with important implications for economic development.
[13] In joint work with Giovanni Peri, Ottaviano investigated the relationship between linguistic diversity across U.S. cities and local productivity over 1970–90; together, they find that wages and employment density of U.S.-born workers were systematically higher, all else equal, in cities with higher linguistic diversity, especially for highly educated and for white workers, and that the relationship was strengthened the better non-native speakers were assimilated in terms of language skills and duration of residence.
