Outline of Final Research Achievements |
We study a multi-regional economic growth model in which people can freely choose their locations. We characterize the stability of regional population distributions at stationary equilibria with the optimization problem of a function called a potential function. We show that people's time preference crucially affects the stable stationary equilibrium through the trade-offs between spatial agglomeration's positive productivity-enhancing effects and negative congestion effects.
We also apply our model to issues of the regional inequality and network. Regarding the first issue, we show that regions where the income perpetually grows and regions where the income stops growing can coexist at a stable stationary equilibrium. Regarding the second issue, we study how the network structure of inter-regional spillovers in production affects the stable stationary equilibrium.
