Countably heterogeneous aggregate-taking games with $\ell^p$-summable player masses for $0<p<1$. A uniform $\ell^p$ restriction on mixed strategies yields a bounded aggregation operator; conditional on the aggregate, purification is without loss, and finite-player existence follows by Kakutani.
Constructs a six-digit SOC exposure index by combining an ensemble technical-exposure score with occupation-industry regulatory incidence, licensing, and time-varying policy uncertainty. A task-based production model identifies regulation as a log-linear wedge between technically feasible automation and realized displacement; validation uses post-2022 employment outcomes and clustered inference.
Uses staggered state executive orders from 2022–2026 to identify the worker-side effects of degree de-gating. A statistical-discrimination model with monopsonistic wage posting separates screening from rent extraction; group-time average treatment effects are estimated with Callaway–Sant'Anna difference-in-differences on ACS and QWI microdata.
