Through an approach of increasing returns, external economy, product differentiation and path-dependence, with foreign trade costs incurred by different regions within the large country discriminated, a model of investment and employment flow is developed as a simulation of a large country′s process of integration with the world economy. The modeling indicates that in the process of integration, as there exist differences in foreign trade costs among different regions within the large country, either the spatial economy of the country deviates from its symmetric structure in autarky and falls into a core-periphery relationship, or the effect of industrial agglomeration is reinforced, amplified and locked in, if the agglomeration had been started. The economic gap on either the aggregate or structural basis between different regions within the large country will increase rapidly as the integration proceeds.展开更多

文摘This paper examines the role of collateral in sudden stop models that feature occasionally binding constraints and endogenous growth.It shows how different assumptions regarding the nature and valuation of collateral alter the dynamics of crisis episodes and the welfare costs of pecuniary externalities.For example,in a model with land as collateral,valuing collateral at the“expected future price”leads to substantially weaker Fisherian deflation efects than the case with collateral valued at the“current price.”However,the average size of sudden stops in the two economies are similar because households endogenously avoid the region where large sudden stops would occur.The differences between different collateral valuations and the size of sudden stops are amplified when we abstract from endogenous growth.In another case,assuming collateral is income rather than land leads to smaller sudden stops as income is less volatile than asset prices.Finally,we show that some choices lead to constrained or conditionally eficient allocations whereas others generate inefficiencies,but these inefficienciesare small.
