Comparing TIP to Wage Subsidies
用企业均衡模型比较税收导向的收入政策、工资补贴和降低工资税的效果，分析TIP如何影响企业的工资和定价决策。
This paper derives some analytic results concerning the possible effects of a tax-based incomes policy (TIP), and compares them to the effects of a wage subsidy or a decreased payroll tax.

Nevertheless, the model can address an important question that lies at the very heart of the issue of the possible effectiveness of a TIP: in what way would a TIP influence a firm to change its wage and price decisions, assuming nothing else in the economy were to be changed. If, as shown below, certain versions of TIP
