Learning Chemistry for an Exciting (and Uncertain) Future

Saving for an uncertain future.

T he units that are subject to selection pressure in evolutionary biology are ‘‘strategies,’’ which are conditional actions (for example, do P if X occurs; otherwise do Q). In contrast, the units in economics (they are called ‘‘people’’) select strategies from available menus so as to further their projects and purposes. If evolutionary dynamics involves mindless competition among strategies, e...

Discounting an uncertain future

The objective of this paper is to determine the socially optimal discount rate for public investment projects that entail costs and benefits in the very long run. We suppose that there is an exogenous process for the growth of consumption per capita, which is stochastic. We first evaluate the determinants of the discount rate for a specific horizon when the representative agent has a recursive ...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Rationally discounting an uncertain future

J. Doyne Farmer & John Geanakoplos Assessing the relative value of a benefit (or harm) in the future vs. the present is a fundamental problem in economics1. The conventional approach is to discount the future exponentially. This can be motivated by the opportunity cost relative to an investment paying fixed interest2. In contrast, real interest rates vary randomly, so the resulting effective di...
