Lerner distinguished between "high" full employment, which was the lowest sustainable unemployment under incomes policies, and "low" full employment, i.e., the lowest sustainable unemployment rate without these policies.
وقد فرق بين التوظيف الكامل "المرتفع" (أقل مستوى بطالة مستدام بموجب سياسات الدخل) والتوظيف الكامل "المنخفض" (أقل مستوى بطالة مستدام بدون هذه السياسات).
