This paper discusses the lean vs. clean policy debate in managing financial crises based on dynamic general equilibrium models with an occasionally binding collateral constraint. We show that a full state-contingent subsidy for debtors can restore the first-best allocations by forestalling...

This paper proposes to balance considerations from welfarism and virtue ethics for normative analysis of economic models with endogenous preferences. Our framework introduces two concepts that are useful in evaluating alternative social states. First, we introduce the moral evaluation function...

This paper develops a dynamic general equilibrium model that explicitly includes a banking sector with a maturity mismatch. We demonstrate that, despite the perfect competition in the banking sector, rational banks take on excessive risks systemically, resulting in overleverage and inefficiently...

This paper documents empirically and analyzes theoretically the responses of disaggregated prices to aggregate technology and monetary policy shocks. Based on the price data of US personal consumption expenditure, we find that disaggregated price responses have features across shocks and across...

An important difficulty in many models of behavioral economics is that preferences are endogenous and unstable. Therefore, preferences may not provide the most desirable yardstick to evaluate social states. This paper proposes unconditional love as a candidate for such a yardstick. The concept...
