Do the retirement patterns of public-sector workers differ from those in the private sector? The latter typically face a retirement landscape with exposure to market uncertainties through defined-contribution pension plans and private saving. Public-sector workers, in contrast, are often covered by defined-benefit pension plans that encourage retirement at relatively young ages and offer financial security at older ages. We examine how private- and public-sector workers transition from full-time career employment, with a focus on the importance of gradual retirement. To our surprise, we find that the prevalence of continued work after career employment, predominantly on bridge jobs with new employers, is very similar in the two sectors, a result with important implications in a rapidly aging society.

This paper investigates the impact of the desire to keep up with the Joneses (KUJ) on economic growth and optimal tax policy in a continuous-time, overlapping-generations model with AK technology and exogenous, gradual retirement. Due to the desire to KUJ, the propensity to consume out of total wealth rises (declines), and the balanced growth rate declines (increases), when the households' individual total (physical and human) wealth is increasing (decreasing) with age. The rate of retirement determines whether or not a household's total wealth is increasing with age. If total wealth is increasing (decreasing) with age, an optimal allocation is decentralized by an intergenerationally progressive (regressive) lump-sum tax system. The desire to KUJ strengthens the intergenerational regressivity (progressivity) of the optimal tax system. The optimal tax implications of the desire to KUJ are a key finding of this paper.
