Quantifying the Inefficiency of the US Social Security System [PDF]
We quantify the inefficiency of the retirement component of the US social security system within a model where agents receive idiosyncratic labor-productivity shocks that are privately observedsocial security, efficient allocations, idiosyncratic ...

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation
Advanced Functional Materials, EarlyView.A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Social Security in Germany: A Prey of Political Opportunism? [PDF]
This paper examines how politicians influenced social security policy in Germany. Using yearly data from the German Pension Insurance from 1957 to 2005, revenues as well as expenditures are analysed in linear regression models, respectively.

Advanced Functional Materials, EarlyView.An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

Aggregate Savings in the Presence of Private and Social Insurance [PDF]
In the presence of uncertain lifetimes, social security has the characteristics of an annuity: a consumer pays a tax when young in exchange for receiving a social security benefit if he survives to be old.

Advanced Functional Materials, EarlyView.This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

Does Social Security Affect Retirement and Labor Supply? Using the Chilean Experience as an Experiment [PDF]
The paper explores the effects of the social security system over retirement and labor supply decision of individuals aged 55 to 65 in Chile. We use the 1998 CASEN survey elaborated by the Chilean government. Due to regulations established by the current

Advanced Healthcare Materials, EarlyView.Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
