Labour Supply in a Two-Period Model: The Effect of a Nonlinear Progressive Income Tax
研究在生命周期模型中引入非线性所得税后，劳动供给的比较静态分析和消费路径如何变化，发现税收的联合或单独征收以及累进性会显著改变传统线性模型的结论。
Earlier studies of labour supply in a life cycle context have typically either neglected taxes completely, or represented the income tax by a linear function. The present paper studies how the qualitative conclusions of a "traditional" life cycle model of labour supply are changed when a nonlinear tax is introduced into the model. It is shown that the comparative statics results, and the characterization of the consumption and labour supply paths, depend critically on whether capital and labour income are taxed jointly or separately, and on the progressivity (nonlinearity) of the income tax. Few of the results valid for a linear income tax carry over to the nonlinear case.
