Abstract
We study bank contributions that ex ante fund government guarantees supported by a fiscal backstop in a general equilibrium setting where banks intermediate between risk-averse households and state-contingent investments. We offer an analytical characterization of optimal bank contributions as a function of household risk-aversion and guarantees. Showing that higher risk-aversion expedites the way bank contributions internalize guarantees' boost of household risk-taking, we establish a non-trivial relationship between optimal bank contributions and household risk-aversion: Higher risk-aversion optimally induces higher contributions when guarantees exceed a threshold; otherwise, higher contributions shall be observed in economies with less risk-averse households.
