Nested potentials and robust equilibria

This paper introduces the notion of nested best-response potentials for complete in- formation games. It is shown that a unique maximizer of such a potential is a Nash equilibrium that is robust to incomplete information in the sense of Kajii and Morris (1997, mimeo).incomplete information, potential games, robustness, refinements

Strategic complementarities and nested potential games

This note shows that every finite game of strategic complementarities is a nested pseudo-potential game defined in Uno (2007, Economics Bulletin 3 (17)) if the action set of each player is one-dimensional, except possibly for one playerStrategic complementarities, potential games, existence of a pure strategy Nash equilibrium

Theory of quasiballistic transport through nanocrystalline silicon dots

A model to describe the underlying physics of high-energy electron emission from a porous silicon diode is presented. The model is based on an atomistic tight-binding method combined with semiclassical Monte Carlo simulation. It well reproduces essential features of experimental findings. An initial acceleration region is shown to play a crucial role in generating quasiballistic electron emission

Current Status and Future Prospects of Electric Power as Automotive Fuel

The deployment of electric vehicles and plug-in hybrid vehicles on the premise of using low-carbon power sources (renewable energy and nuclear power) is expected to not only contribute to a stable energy supply by lowering dependence on oil (dependence on foreign supply sources) as fuel but also help to reduce CO2 emissions. Moreover, the use of night-time electricity is likely to help spread the use of electric vehicles for commuter use by reducing energy cost. However, it is important to remember that if conventional electricity, mainly generated by coal-fired power plants, is to be used as a power source, the deployment of electric vehicles and plug-in hybrid vehicles may not necessarily be effective in reducing CO2 emissions. It is also true that compared with vehicles powered by an internal-combustion engine, electric vehicles still have some shortcomings, such as their short driving range, some 100 km on a single charge of the battery, and the long battery-recharging time. To significantly increase the use of electric vehicles in the future, the key will be to develop a low-cost, high-performance battery. It will also be necessary to further reduce the cost of wind and photovoltaic power generation. As the use of electric vehicles spreads, it will become necessary to conduct a quantitative study on the optimization (cost minimization) of the power source mix (cost minimization), including additional power sources for automobiles.electric vehicles, optimization, power source
