Asset shortages, liquidity and speculative bubbles

Gaetano Bloise and A. Citanna

Journal of Economic Theory, 2019, vol. 183, issue C, 952-990

Abstract: We study the effect of asset shortages on liquidity in economies with limited enforcement of debt contracts. We establish that, under a suitable assumption in terms of gains from trade, liquidity does not dry up and trading volumes do not disappear as credit conditions worsen. The equilibrium outcome becomes arbitrarily close to a purely speculative equilibrium, and bubbles occur in the limit. The result applies to incomplete markets and, more generally, to equilibria where collateral constraints interfere with the additivity of the payoff pricing functional.
