Määttänen, Niku; Poutvaara, Panu (2007): Should old-age benefits be earnings-tested? IZA Discussion Papers / Forschungsinstitut für Zukunft und Arbeit, Bonn, 2616
Full text not available from 'Open Access LMU'.


We study the welfare effects of earnings testing flat-rate old-age benefits in a quantitative overlapping generations model with idiosyncratic labor income risk. In our model economy, even a moderate earnings testing reduces individuals’ expected lifetime utility, whenever other taxes are taken into account. Moreover, it also lowers the realized lifetime utilities of those at the bottom of the lifetime utility distribution.
