Ascertaining progress in building age-friendly cities (AFCs) requires community diagnostic indicators. This study examines the relationship between social participation and happiness at municipal level. The data from Japan Gerontological Evaluation Study (JAGES) 2013, 2016, 2019, comprising 442,079 older people 289 municipalities, are used. We also employ linear mixed-effects models to evaluate association happiness. In these models, we adjust for seven variables as potential confounders....

We introduce the groupwise-pivotal referral (GPR) mechanism for auctions where buyers can participate only through referrals. Each buyer's type consists of a valuation and referable buyers. Unlike second-price auction (SPA), Vickrey-Clarke-Groves (VCG) provides incentives. However, VCG is not budget-feasible. In contrast, GPR core-selecting, implying efficiency budget feasibility. GPR, bidders should refer truthfully have no incentive to underbid. shill-proof groupwise collusion-proof....
