    Replacing the Replacement Rate: How Much is "ENOUGH" Retirement Income?

    For years, the standard for measuring retirement income adequacy has been the final earnings replacement rate (usually targeted at 70%). Financial planners, actuaries, pension plan advisors, academics and public policy analysts all use this benchmark. It’s the measure that underlies our pension systems, drives the research that determines whether populations are prepared (or not) for retirement and serves as the backbone of retirement planning software.

    But the question is, does it work? Will 70% of a worker’s final annual employment earnings actually sustain his or her living standards after retirement?

    This presentation examines whether workers who hit this target actually can expect to maintain their living standards in retirement.  Bonnie-Jeanne will also discuss an alternative, more accurate, basis for assessing how well a worker’s living standards are maintained after retirement - the Living Standards Replacement Rate.

Research interests

Professor Wu has a primary research interest in the design and analysis of complex surveys. His research also covers more broad topics including semiparametric and nonparametric methods, resampling (jackknife and bootstrap) techniques, missing data and measurement error problems. He has worked extensively on empirical likelihood (EL) methods and related computational procedures, with strong interest in developing R packages for practical implementations of the EL methods.
