We explore the possibility of designing matching mechanisms that can accommodate non-standard choice behavior. pin down necessary and sufficient conditions on participants' behavior for existence stable incentive compatible mechanisms. Our results imply well-functioning markets be designed to adequately a plethora behaviors, including standard is consistent with preference maximization. To illu...

Abstract We study the possibility of generating baryon asymmetry universe from dark matter (DM) annihilations during non-standard cosmological epochs. Considering DM to be weakly interacting massive particle (WIMP) type, generation via leptogenesis route is studied where WIMP annihilation produces a non-zero lepton asymmetry. Adopting minimal physics model realise this along with light neutrino...
