Robustness of statistical models
Andrea Loi, Stefano Matta
A statistical structure on a smooth manifold induced by is said to be {\em robust} if there exists an open neighborhood of in…
Risk aversion and uniqueness of equilibrium: a polynomial approach
Andrea Loi, Stefano Matta
We study the connection between risk aversion, number of consumers and uniqueness of equilibrium. We consider an economy with two goods and impatience types, where each type ha…
A note on local uniqueness of equilibria: How isolated is a local equilibrium?
Stefano Matta
The motivation of this note is to show how singular values affect local uniqueness. More precisely, Theorem 3.1 shows how to construct a neighborhood (a ball) of a regular equilibr…
Minimal entropy and uniqueness of price equilibria in a pure exchange economy
Andrea Loi, Stefano Matta
We introduce uncertainty into a pure exchange economy and establish a connection between Shannon's differential entropy and uniqueness of price equilibria. The following conjecture…
