This paper presents a spatial model of a city with two unequally productive jurisdictions. City residents bear a commuting cost to work in either of the two jurisdictions. In each jurisdiction, a fixed public budget must be financed with a wage tax and a head-tax. We compare the first best...

Non-renewable and renewable resources are imperfect substitutes due to technical and geographical constraints. What is the role of imperfect substitution on the optimal transition path to the clean technologies? We address this question by characterizing the optimal growth path and resource use...

The built environment plays a key role in the strategy of “Aging in Place”. Here, we study the influence of the built environment on the health status of elderly people living in Brussels. Using census and geocoded data, we analysed if built environment factors were associated with poor...

This paper considers whether countries might mutually agree a policy of open borders, allowing free movement of workers across countries. For the countries to agree, the short run costs must outweighed by the long term benefits that result from better labor market flexibility and income...

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...

We explore the evolutionary dynamics of a population that consists of cooperators and defectors, wherein each member of the many pairs of players of a one-shot prisoner's dilemma game is drawn at random, and the number of descendents positively depends on the payoffs in the game. We demonstrate...

Economic regions, such as urban agglomerations, face external demand and price shocks that produce income risk. Workers in large and diversified agglomerations may benefit from reduced wage volatility, while firms may outsource the production of intermediate goods and realize benefits from...

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...

Consider an overlapping generation growth model involving identical countries whose fiscal policy reduces to a pay-as-you-go system with flat rate benefits and uniform payroll tax rate. In autarky, the tax rate is chosen so as to achieve a compromise between intragenerational and...
