Abstract

Automation affects public budgets through wages and the tax base, and also through inflows into social insurance. We estimate the effect of industrial robot exposure on Social Security Disability Insurance (SSDI) applications using confidential commuting-zone data and a shift-share design that instruments U.S. exposure with earlier European robot diffusion. One additional robot per 1,000 workers lowers applications by about 8 per 100,000 working-age residents, with the largest declines among workers aged 55 to 64. Employment-to-population ratios do not fall in exposed commuting zones, which weighs against broad local displacement as the sole explanation. A year's flow of averted applications corresponds to about \$3.4 billion in expected SSDI and Medicare obligations, or about \$17,000 per robot-year, in present value rather than realized cash. Displacement adds to social-insurance costs, whereas robot exposure here reduces them, an offset that assessments built only on displacement leave unpriced.

Local Media and the Shaping of Social Norms: Evidence from the Ebola outbreak

Media's influence on norms and behavior is widely recognized. Less is known about the role played by media being local. I examine this in a high-stakes context, the Ebola outbreak in Guinea. I exploit quasi-random variation in access to radio and the timing of a public-health campaign aired on community radio. I find that 12-17% of Ebola cases could have been prevented if places with access to a neighboring community radio station had instead had their own. Impacts are driven by radio being local rather than by ethno-linguistic belonging. Local media facilitates coordination in behaviors observed and sanctioned locally.

Productivity Shocks and Input Misallocation: A Decomposition

This paper asks how much input misallocation productivity uncertainty generates and at which stage of input decisions it arises. I separate revenue productivity by when each component is revealed and trace each into the gap between an input's marginal revenue product and its price. In six European countries, shocks revealed after an input is committed account for 20 percent of capital gap dispersion and 5 percent of labor gap dispersion. An unanticipated one percent rise in productivity raises the capital gap by 0.92 percent and the labor gap by 0.19 percent, because most of the shock passes into the wage.

When Do Type-Specific Wages Buffer Distributional Incidence in TANK?

When do relative wages buffer the unequal incidence of aggregate shocks? I derive a consumption-gap decomposition and a present-value condition for partial offset in a TANK model. An extension separates wage-setting demand elasticity from substitution between labor segments and allows each segment to contain both financial types. With a zero inherited wage gap and a same-sign discounted wedge, substitution above one gives offsetting earnings reallocation; substitution below one gives amplification. The channel disappears when financial types have identical segment exposure. Numerical experiments assess these mechanisms, shock persistence, policy feedback, and aggregate-IRF matching. In the nested perfect-alignment monetary benchmark, the peak consumption gap is about two-fifths smaller under type-specific wages than under the common-wage closure. These are conditional model comparisons, not empirical effect estimates or welfare rankings.
