Energy Storage and Renewable Energy [PDF]
SSRN Electronic Journal, 2014 I consider an economy with fossil fuel and renewable energy and energy storage, and search for the conditions that lead to welfare improvements when energy is stored. I then solve for the optimal decision rule and analyze the long-run tendencies of the economy-energy variables. The findings are threefold.

Tri-bimaximal and bimaximal neutrino mixing from discrete symmetries [PDF]
, 2009 The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently it has been shown that also the bimaximal pattern could be a very good starting point in order to describe the lepton mixing.
