Can the Scala Mobile Explain the Fall and Rise of Earnings Inequality in Italy? A Semiparametric Analysis, 1977–1993
利用意大利家庭收入与财富调查数据，分析滑动工资制（一种随物价上涨给所有员工相同绝对加薪的机制）在1977-1993年间对收入不平等先降后升的作用，认为80年代中期后不平等的上升是对前期该机制压缩工资差距的回应。
This article uses Survey of Households' Income and Wealth microdata to investigate the role the Scala Mobile played in the initial fall and subsequent rise in earnings inequality in Italy between 1977 and 1993. The Scala Mobile was a wage indexation mechanism granting the same absolute wage increase to all employees as prices rose, thereby potentially compressing wage differentials. Over time, the potential equalizing effect of this mechanism fell. This article argues that the rise in inequality from the mid-1980s was a response to the compression of differentials operated over the previous years by the Scala Mobile.
