ABSTRACT

This paper analyses US payroll share and components across states for the period 1977–2017. Findings include that spatial clustering in payroll shares decreased until the year 2000. States are clustered in low and high productivity groups. We relate this phenomenon to dualism. High labour productivity states featured high payroll shares early on, but now feature low payroll shares. We label this phenomenon decoupling of labour productivity from real wages. A Divisia Decomposition documents that Rust Belt states dominated the decline in US payroll share in the 1980s, whereas more recently large (coastal) states dominated. While we do not explain (potentially different) mechanisms, decoupling is apparent throughout.

摘要

本文分析了 1977-2017 年期间美国各州的工资份额和组成部分。调查结果包括，直到 2000 年，工资份额的空间聚类下降。各州聚集在低和高生产力组中。我们将这种现象与二元论联系起来。劳动生产率高的州在早期以高工资份额为特征，但现在以低工资份额为特征。我们将这种现象称为劳动生产率与实际工资脱钩。Divisia Decomposition 文件表明，锈带州在 1980 年代主导了美国工资份额的下降，而最近的大型（沿海）州则占主导地位。虽然我们没有解释（可能不同的）机制，但脱钩自始至终都是显而易见的。
