  1. Many government programs transfer resources to older people and implicitly or explicitly tax their labor. We shed new light on the labor supply and welfare effects of such programs by investigating the Old Age Assistance Program (OAA). Exploiting the large differences in OAA programs across states and Census data on the entire US population in 1940, we find that OAA reduced the labor force participation rate among men aged 65–74 by 8.5 percentage points, more than one-half of its 1930–1940 decline, but that OAA’s implicit taxation of earnings imposed only small welfare costs on recipients.

  2. Abstract Age-related reductions in neural selectivity have been linked to cognitive decline. We examined whether age differences in the strength of retrieval-related cortical reinstatement could be explained by analogous differences in neural selectivity at encoding, and whether reinstatement was associated with memory performance in an age-dependent or an age-independent manner. Young and older adults underwent fMRI as they encoded words paired with images of faces or scenes. During a subsequent scanned memory test participants judged whether test words were studied or unstudied and, for words judged studied, also made a source memory judgment about the associated image category. Using multi-voxel pattern similarity analyses, we identified robust evidence for reduced scene reinstatement in older relative to younger adults. This decline was however largely explained by age differences in neural differentiation at encoding; moreover, a similar relationship between neural selectivity at encoding and retrieval was evident in young participants. The results suggest that, regardless of age, the selectivity with which events are neurally processed at the time of encoding can determine the strength of retrieval-related cortical reinstatement.
