A Case for Incomplete Markets

No 313, Economics Series from Institute for Advanced Studies

Abstract: We propose a new welfare criterion that allows us to rank alternative financial market structures in the presence of belief heterogeneity. We analyze economies with complete and incomplete financial markets and/or restricted trading possibilities in the form of borrowing limits or transaction costs. We describe circumstances under which various restrictions on financial markets are desirable according to our welfare criterion.
