Matching to share risk
Pierre-André Chiappori, Philip J. Reny
Abstract
We consider a matching model in which individuals belonging to two
populations (\textquotedblleft males\textquotedblright\ and
\textquotedblleft females\textquotedblright ) can match to share their
exogenous income risk. Within each population, individuals can be ranked by
risk aversion in the Arrow-Pratt sense. The model permits non transferable
utility, a context in which few general results have previously been
derived. We show that in this framework a stable matching always exists, it
is generically unique, and it is negatively assortative: for any two matched
couples, the more risk averse male is matched with the less risk averse
female.
Keywords: Negatively assortative matching, risk-sharing, stable match
