Income sharing for common pool resources with uncertain productivity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence ...

Physical Properties of Transition Metal Hydride Superconductors Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) by First‐Principles Calculations

open access: yesAdvanced Physics Research, EarlyView.
The electronic band structure determines all the charge transport properties of crystalline solids. It also controls the optical response of the material. Bonding characters are strongly influenced by the band structure. The band structures of Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) compounds shown above confirm their metallic nature.
