Union Wage Policy: The Importance of Labour Mobility and the Degree of Centralization
研究了工会工资设定在不同集中程度下对失业的影响，发现全国性工资设定比分散设定失业率更低，但中间层次设定可能失业率最高。动态模型显示，劳动力流动性越高，工会选择的工资越低；除非流动性极高，否则集中程度越高工资越低。
With endogenous product prices, nationwide wage-setting gives lower unemployment than decentralized wage-setting. However, intermediate-level wage-setting may give more unemployment than both completely decentralized and completely centralized wage-setting. The main part of the paper considers a dynamic model, which includes flows of workers between firms and in and out of unemployment. With less than full centralization, the wages chosen by unions are lower the higher is the degree of labor mobility. Wages are also lower the higher is the degree of centralization, unless labor mobility is very high. Copyright 1991 by The London School of Economics and Political Science.
