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. We show that high and low trade costs imply that all regions involve a positive share of the...

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...

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...

The purpose of this paper is twofold. First, we present an alternative model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this...

The objective of this paper is to consider interregional differentials in a unified framework by explicitly incorporating land for housing, and to conduct an empirical analysis of the interregional differential indexes. It is revealed that between regions the CPI varies little, the wage rate...

New economic geography focuses on the impact of falling transport costs on the spatial distribution of activities. However, it disregards the role of technological innovations, which are central to modern economic growth, as well as the role of migration costs, which are a strong impediment to...
