Do Stronger Employment Discrimination Protections Decrease Reliance on Social Security Disability Insurance? Evidence from the U.S. Social Security Reforms

The United States Social Security Amendments of 1983 (SSA1983) increased the full retirement age (FRA) and increased penalties for retiring before the FRA. This cut to retirement benefits caused spillover effects on Social Security Disability Insurance (SSDI) applications and receipt by making SSDI relatively more generous. We explore if stronger disability and age discrimination laws moderated these spillovers, using variation whereby many state laws are broader or stronger than federal law. We estimate the effects of these laws on SSDI applications and receipt using a difference-in-differences approach, comparing cohorts affected by SSA1983 to similarly aged unaffected cohorts, across states. We find that a broader definition of disability, where only a medically diagnosed condition is required to be covered under state law, significantly reduces SSDI applications induced by SSA1983, but has no effect on SSDI receipt, likely because the foregone applications were for those with less severe conditions that were unlikely to have been approved for SSDI. We find some evidence that other broader or stronger features of state disability discrimination laws reduce both SSDI applications and receipt. We do not find much evidence that age discrimination laws reduce spillovers to SSDI. These results suggest that broader and stronger disability discrimination laws reduce employment barriers, allowing older individuals to work longer, possibly reducing reliance on SSDI and costly applications to SSDI

Estimating the Effects of the ADA Amendments Act on the Hiring and Termination of Individuals with Disabilities, Using New Disability Categorizations

Disability discrimination laws are often used to potentially increase employment for individuals with disabilities. However, legal theory and empirical economics research do not provide conclusive answers as to how expansions in disability discrimination laws affect economic outcomes, namely hiring rates, for individuals with disabilities. We estimate the effect of the ADA Amendments Act (ADAAA) on employment transitions: hirings and terminations for individuals with disabilities relative to those without disabilities. To calculate employment transitions, we use data from the Survey of Income and Program Participation (SIPP). We also use the SIPP to develop additional measures and categorizations of disability based on whether the conditions are physical or mental, and whether they are salient to an employer at the hiring stage. We find that the ADAAA is generally associated with positive employment effects: increases or no effects on hiring rates, and decreases or no effects on termination rates. Our strongest and most robust results are that we find increases in hiring for those with nonsalient physical conditions and decreased terminations for those with salient physical conditions. Our results suggest that the effects of the ADAAA vary by disability type—especially by disability saliency—and are stronger for the groups most targeted by broader coverage of the ADAAA

We provide evidence from a field experiment — a correspondence study — on age discrimination in hiring for retail sales jobs. We collect experimental data in all 50 states and then relate measured age discrimination — the difference in callback rates between old and young applicants — to variation across states in antidiscrimination laws offering protections to older workers that are stronger than the federal age and disability discrimination laws. We do a similar analysis for nonexperimental data on differences across states in hiring rates of older versus younger workers. The experimental evidence points consistently to evidence of hiring discrimination against older men and more so against older women. However, the evidence on the relationship between hiring discrimination against older workers and state variation in age and disability discrimination laws is not so clear; at a minimum, there is not a compelling case that stronger state protections reduce hiring discrimination against older workers. In contrast, the nonexperimental evidence suggests that stronger disability discrimination protections increase the relative hiring of older workers.Social Security Administration, RRC08098401, UM16-04,http://deepblue.lib.umich.edu/bitstream/2027.42/135722/1/wp349.pdfDescription of wp349.pdf : Working pape

Did Age Discrimination Protections Help Older Workers Weather the Great Recession?

We examine whether stronger age discrimination laws at the state level moderated the impact of the Great Recession on older workers. We use a difference-in-difference-in-differences strategy to compare older workers in states with stronger and weaker laws, to their younger counterparts, both before, during, and after the Great Recession. We find very little evidence that stronger age discrimination protections helped older workers weather the Great Recession, relative to younger workers. The evidence sometimes points in the opposite direction, with stronger state age discrimination protections associated with more adverse effects of the Great Recession on older workers. We suggest that this may be because during an experience like the Great Recession, severe labor market disruptions make it difficult to discern discrimination, weakening the effects of stronger state age discrimination protections, or because higher termination costs associated with stronger age discrimination protections do more to deter hiring when future product and labor demand is highly uncertain.Social Security Administrationhttp://deepblue.lib.umich.edu/bitstream/2027.42/102262/1/wp287.pd

Is It Harder for Older Workers to Find Jobs? New and Improved Evidence from a Field Experiment

We design and implement a large-scale resume correspondence study to address limitations of existing field experiments testing for age discrimination that may bias their results. One limitation that may bias results is giving older and younger applicants similar experience to make them “otherwise comparable.” A second limitation is that greater unobserved differences in human capital investment of older applicants may bias the results against finding age discrimination. On the basis of over 40,000 job applications, we find robust evidence of age discrimination in hiring against older women, especially those near retirement age, but considerably less evidence of age discrimination against men

Experimental Age Discrimination Evidence and the Heckman Critique

We design and implement a large-scale field experiment on age discrimination to address limitations of past research that may bias their results. One limitation is the practice of giving older and younger applicants similar experience in the job to which they are applying, to make them "otherwise comparable." The second limitation is ignoring the likelihood of greater variation in unobserved differences among older workers owing to human capital investment. Based on evidence from over 40,000 job applications, we find robust evidence of age discrimination in hiring against older women, but considerably less evidence of age discrimination against older men

Diurnal variations in multi-sensor wearable-derived sleep characteristics in morning- and evening-type shift workers under naturalistic conditions

Consumer-grade, multi-sensor, rest-activity trackers may be powerful tools, to help optimize rest-activity management in shiftwork populations undergoing circadian misalignment. Nevertheless, performance testing of such devices under field conditions is scarce. We previously validated Fitbit Charge 2TM against home polysomnography and now evaluated the potential of this device to document differences in rest-activity behavior, including sleep macrostructure, in first-responder shift workers in an operational setting. We continuously monitored 89 individuals (54% females; mean age: 33.9 ± 7.7 years) for 32.5 ± 9.3 days and collected 2,974 individual sleep episodes scattered around the clock. We stratified the study participants according to their self-reported circadian preference on the reduced Horne-Östberg Morningness-Evening Questionnaire (rMEQ; the scores from 4 participants were missing). Fitbit estimates of sleep duration, wakefulness after sleep onset (WASO), REM sleep percentage in the first NREM-REM sleep cycle, and REM sleep latency formed approximately sinusoidal oscillations across 24 hours. Generalized additive mixed model analyses revealed that the phase position of sleep duration minimum was delayed by 2.8 h in evening types (ET; rMEQ ≤ 11; n = 20) and by 2.6 h in intermediate types (IT; 11 < rMEQ < 18; n = 45) when compared to morning types (MT; rMEQ ≥ 18; n = 20). Similarly, the phase position of WASO was delayed by 2.7 h in ET compared to MT. While nocturnal sleep duration did not differ among the three groups, sleep episodes during the biological day decreased in duration from ET to IT to MT. Together, the findings support the notion that a consumer-grade, rest-activity tracker allows estimation of behavioral sleep/wake cycles and sleep macrostructure in shift workers under naturalistic conditions that are consistent with their self-reported chronotype

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Effects of antiplatelet therapy after stroke due to intracerebral haemorrhage (RESTART): a randomised, open-label trial

Background: Antiplatelet therapy reduces the risk of major vascular events for people with occlusive vascular disease, although it might increase the risk of intracranial haemorrhage. Patients surviving the commonest subtype of intracranial haemorrhage, intracerebral haemorrhage, are at risk of both haemorrhagic and occlusive vascular events, but whether antiplatelet therapy can be used safely is unclear. We aimed to estimate the relative and absolute effects of antiplatelet therapy on recurrent intracerebral haemorrhage and whether this risk might exceed any reduction of occlusive vascular events. Methods: The REstart or STop Antithrombotics Randomised Trial (RESTART) was a prospective, randomised, open-label, blinded endpoint, parallel-group trial at 122 hospitals in the UK. We recruited adults (≥18 years) who were taking antithrombotic (antiplatelet or anticoagulant) therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage, discontinued antithrombotic therapy, and survived for 24 h. Computerised randomisation incorporating minimisation allocated participants (1:1) to start or avoid antiplatelet therapy. We followed participants for the primary outcome (recurrent symptomatic intracerebral haemorrhage) for up to 5 years. We analysed data from all randomised participants using Cox proportional hazards regression, adjusted for minimisation covariates. This trial is registered with ISRCTN (number ISRCTN71907627). Findings: Between May 22, 2013, and May 31, 2018, 537 participants were recruited a median of 76 days (IQR 29–146) after intracerebral haemorrhage onset: 268 were assigned to start and 269 (one withdrew) to avoid antiplatelet therapy. Participants were followed for a median of 2·0 years (IQR [1·0– 3·0]; completeness 99·3%). 12 (4%) of 268 participants allocated to antiplatelet therapy had recurrence of intracerebral haemorrhage compared with 23 (9%) of 268 participants allocated to avoid antiplatelet therapy (adjusted hazard ratio 0·51 [95% CI 0·25–1·03]; p=0·060). 18 (7%) participants allocated to antiplatelet therapy experienced major haemorrhagic events compared with 25 (9%) participants allocated to avoid antiplatelet therapy (0·71 [0·39–1·30]; p=0·27), and 39 [15%] participants allocated to antiplatelet therapy had major occlusive vascular events compared with 38 [14%] allocated to avoid antiplatelet therapy (1·02 [0·65–1·60]; p=0·92). Interpretation: These results exclude all but a very modest increase in the risk of recurrent intracerebral haemorrhage with antiplatelet therapy for patients on antithrombotic therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage. The risk of recurrent intracerebral haemorrhage is probably too small to exceed the established benefits of antiplatelet therapy for secondary prevention
