Retirement Implications of a Low Wage Growth, Low Real Interest Rate Economy

We examine the implications of persistent low real interest rates and wage growth rates on individuals nearing retirement. We begin by reviewing the concept of r star – the long-term real, safe interest rate that is neither expansionary nor contractionary – and presenting recent estimates suggesting that this value has declined. We then examine the implications of low returns and low wage growth for individuals currently aged 45 and 55. We find that low returns and low wage growth have substantial welfare effects, with compensating variations that are often in the hundreds of thousands of dollars. Low returns increase optimal Social Security claiming ages and the marginal benefit of working longer, while low wage growth decreases the marginal benefit of working longer. Low economy-wide wage growth has a much larger welfare effect than low individual wage growth due to wage indexation of the initial benefit and the progressivity of the Social Security benefit formula. When individual wage growth alone is low, wage indexation is unchanged, and the progressivity of the benefit formula provides insurance. When economy-wide wage growth is low, wage indexation is less generous and there is no insurance benefit from progressivity as average wages fall along with individual wages.
Household Responses to Transfers and Liquidity: Evidence from Social Security's Survivors Benefits

NBER Program(s):Aging, Labor Studies, Public Economics
We use administrative tax data that cover the U.S. population to identify the causal effects of Social Security’s survivors benefit receipt on American families’ behavior and financial well-being. We analyze over a quarter of a million widowed households in which the husband died between 2002-2007, and we exploit a sharp age discontinuity in benefit eligibility to study the responses of financially vulnerable households to government transfers. We first study how households respond to unanticipated benefit receipt in the immediate periods following a large financial shock to investigate the protective role of transfers. We find significant impacts of the program on newly-widowed families’ net income and labor supply behavior, which points to considerable allocative inefficiencies in the life insurance market and to a high valuation of survivors benefits in protecting Americans against mortality shocks. Second, to investigate the particular role of liquidity and benefit timing, we then study how already-widowed women’s labor supply responds to anticipated survivors benefit receipt. We find considerable responses to cash-on-hand via benefit availability that underscore allocative inefficiencies in the credit market and the value of liquidity itself provided by government transfers. These responses and their heterogeneity highlight mechanisms that underlie the labor supply behavior of older vulnerable households, and they point to liquidity constraints, rather than myopia or benefit-schedule misperceptions, as the likely operative channel. Our results have implications for survivors benefits in the U.S., and, more generally, for retirement behavior and response mechanisms to transfers among older vulnerable populations.
Employer Concerns and Responses to an Aging Workforce
NBER Working Paper No. 25572
Issued in February 2019
NBER Program(s):Aging
Economist and public policy analysts have devoted considerable research to examining the work and retirement decisions of employees. Much less effort has been spent on understanding the concerns and challenges of employers if their workers delay retirement and remain on the job until older ages. In this study, we report findings from three employer surveys with the objective of learning how organizations are responding to the aging of their workforces. The surveys provide several important observations. First, employer concerns about workforce aging vary considerably across the economy. To some firms, these demographic changes are of immediate concern and are viewed as a significant risk to the organization while other firms remain more concerned about potential productivity and cost effect of an older labor force. Second, most employers expect the importance of workforce aging to increase in the next five years. In response, a significant proportion of organizations are making changes to working conditions and compensation policies. Third, firms remain reluctant to adopt formal phased retirement policies but are more willing to offer part-time employment, return to work, and other policies on a case by case basis.
