We study a continuous time contracting problem with risk taking in which size plays a role. The agent may take on excessive risk to enhance short-term gains; doing so exposes the principal to large, infrequent (poisson) losses. The optimal contract must use size as an instrument; there is...

We build a stylized dynamic general equilibrium model with financial frictions to analyze costs and benefits of capital requirements in the short-term and long-term. We show that since increasing capital requirements limits the aggregate loan supply, the equilibrium loan rate spread increases,...
