Equilibrium policies when preferences are time inconsistent
Ivar Ekeland, Ali Lazrak
This paper characterizes differentiable and subgame Markov perfect equilibria in a continuous time intertemporal decision problem with non-constant discounting. Capturing the idea…
A Numerical Approach to the Estimation of the Solutions of some Variational Problems with Convexity Costraints
Ivar Ekeland, Santiago Moreno
We present an algorithm to approximate the solutions to variational problems where set of admissible functions consists of convex functions. The main motivator behind this numerica…
An optimal matching problem
Ivar Ekeland
Given two measured spaces (X,dx), (Y,dy) and a third space Z, given two functions u(x,z) and v(x,z), we study the problem of finding two maps s from X to Z and t from Y to Z such t…
A duality theory for some non-convex functions of matrices
Ivar Ekeland
We study a special class of non-convex functions which appear in nonlinear elasticity; and we prove that they have well-defined Legandre transforms. Several examples are given, and…
