Cities - especially those with substantial poor populations - will face increasingly severe challenges in tackling the impacts of global environmental change (GEC). As economic dynamos and increasingly important population concentrations, cities both contribute substantially, and often are very...

We describe a rational expectations model in which speculative bubbles in house prices can emerge. Within this model both speculators and their lenders use interest-only mortgages (IOs) rather than traditional mortgages when there is a bubble. Absent a bubble, there is no tendency for IOs to be...

The authors construct a dynamic general equilibrium model of cities and use it to estimate the effect of local agglomeration on per capita consumption growth. Agglomeration affects growth through the density of economic activity: higher production per unit of land raises local productivity....

The extremely large disparities in employment rates across Italian regions, and the bad performance of the Italian economy in terms of job creation in the 80´s and early 90´s make job creation a top-priority in the economic policy agenda. This paper uses data on employment from 784 Local Labor...

The paper outlines a static equilibrium model, which analyses the economic development in a two-country case by considering interregional migration in R&D-sectors. The effects of migration and firm decisions on both industrial agglomeration and economic development will be shown: lock-in-effects...

The systems of innovation (SI) approach has been established and extended during the last two decades. Although elementary goals and progress have been reached through seminal contributions by Freeman (1987), Lundvall (1992) or Nelson (1993), in designing a generic approach, displaying the...

We use data on wages and rents in different U.S. cities to assess the amenity effects on production and consumption of cultural diversity as measured by diversity of countries of birth of city residents. We show that US-born citizens living in metropolitan areas where the share of foreign-born...

We investigate the existence of wage premium due to cultural diversity across US cities. Using census data from 1970 to 1990, we find that at the urban level richer diversity is systematically associated with higher average nominal wages for white US-born males. We measure cultural diversity in...

The question of the spatial impacts of Information and Communication Technology (ICT) has animated intellectual and policy debate for a long time. At the beginning of the 1990s the advent of the Internet brought a new surge of debate: it was argued that the Internet would free the economy from...
