The Importance of Bundling in a Gorman-Lancaster Model of Earnings
构建了一个多部门戈尔曼-兰开斯特线性特征收入模型，其中工人无法拆分其技能，给出了特征在各行业统一定价的条件，并利用美国劳动力市场数据拒绝了统一定价假设。
This paper considers a multisector Gorman-Lancaster linear characteristics model of earnings in which workers cannot unbundle their skills. Conditions are presented under which characteristics are uniformly priced across sectors. Empirical evidence is presented for the U.S. labour market that rejects the hypothesis of uniform pricing of characteristics.
