We study the effects of decrease in trade costs on the spatial distribution of industry in multi-regional economy, when a rise in the regional population of workers generates higher urban costs. We show that high and low trade costs imply the all regions involve positive share of the industrial...

We study the effects of a decrease in inter-city transport costs on the spatial distribution of population in a multi-regional economy, when a rise in the regional population generates higher urban costs. Holding the number of cities constant, as transport costs are reduced gradually from a very...

We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. When the number of cities is unaffected by falling trade costs, small cities become smaller for...

Asymptotic stability of equilibrium is often difficult to know when the number of variables exceeds four, since all eigenvalues of the Jacobian matrix are not analytically solvable. However, we obtain stability conditions for a general class of migration dynamics without computing eigenvalues....

In this paper, we estimated the net agglomeration economies both in production side and in consumption side using Japanese city data around 1990, when interregional net migration nearly ceased. We showed that doubling city size increases that nominal wage about 10% while it decreases the real...

We show that how spatial evolution is different between the two representative models of economic geography: Krugman (1991 JPE) and Ottaviano et al. (2002 IER). We analyze the impacts of falling transport costs on the spatial distribution of economic activities and welfare for three regions...

We consider an economic geography model of a new genre: all firms and workers are mobile and their agglomeration within a city generates rising urban costs through competition on a land market. When commuting costs are high (low), the industry tends to be agglomerated (dispersed). With two...

In this paper, we estimated the net agglomeration economies in the consumption side as well as the production side using Japanese city-based data of 1992, when interregional net migration nearly ceased. We showed that doubling city size increases the nominal wage by approximately 10% but...

This paper is motivated by the fact that, contrary to its importance in practice, the role of land for production has received no attention in the new trade theory and the new economic geography. We set up a simple monopolistic competition model and we show that, due to the factor proportions...
