Wages and Employment in a Segmented Labor Market
分析商业周期波动如何影响分割为工会化主要部门和竞争性次要部门的劳动力市场，发现衰退会扩大部门间工资差距，且主要部门就业波动更大，符合美国经济典型事实。
This paper analyzes the impact of business cycle fluctuations on a labor market segmented into a unionized primary sector and a "competitive" secondary sector. Either permanent or temporary changes in real aggregate demand are shown to widen the intersectoral wage differential in recession and, under reasonable specifications of key parameters, to cause greater fluctuations of primary-sector employment than secondary-sector employment. This pattern agrees with the stylized facts of the U. S. economy.
