Factor Mobility, Risk and Redistribution in the Welfare State
研究了经济一体化降低要素流动成本后，如何通过风险分担机制削弱福利国家再分配政策的社会保险功能，对理解全球化与福利国家矛盾有参考价值。
Economic integration reduces the costs of factor mobility, producing efficiency gains and contributing to equalization of net factor returns. This raises the 'cost' of income-redistribution policy, thus threatening a basic function of the welfare state. A simple model of costly factor mobility under uncertainty shows that greater factor mobility enables factor owners to pool industry-specific, region-specific, or occupation-specific risks (due to uncertain technology or terms of trade). Economic integration may, thus, reduce some of the potential social insurance benefits of redistributive policy. Copyright 1995 by The editors of the Scandinavian Journal of Economics.
