We develop a model of financial crises with both a financial amplification mechanism, via frictional intermediation, and a role for sentiment, via time-varying beliefs about an illiquidity state. We confront the model with data on credit spreads, equity prices, credit, and output across the financial crisis cycle. In particular, we ask the model to match data on the frothy pre-crisis behavior of asset markets and credit, the sharp transition to a crisis where asset values fall, disintermediation occurs and output falls, and the post-crisis period characterized by a slow recovery in output. We find that a pure amplification mechanism quantitatively matches the crisis and aftermath period but fails to match the pre-crisis evidence. Mixing sentiment and amplification allows the model to additionally match the pre-crisis evidence. We consider two versions of sentiment, a Bayesian belief updating process and one that overweighs recent observations. We find that both models match the crisis patterns qualitatively, generating froth pre-crisis, non-linear behavior in the crisis, and slow recovery. The non-Bayesian model improves quantitatively on the Bayesian model in matching the extent of the pre-crisis froth.

We provide an equilibrium analysis of the efficiency properties of simultaneous bilateral tariff negotiations in a three-country model of international trade. We consider the setting in which discriminatory tariffs are allowed, and we utilize the “Nash-in-Nash” solution concept of Horn and Wolinsky (1988). We allow for a general family of political-economic country welfare functions and assess efficiency relative to these welfare functions. We establish a sense in which the resulting tariffs are inefficient and too low, so that excessive liberalization occurs from the perspective of the three countries.

We study the impact of marital property legislation passed in the US South in the 1840s on households’ investment in risky, entrepreneurial projects. These laws protected the assets of newly married women from creditors in a world of virtually unlimited liability. We compare couples married after the passage of a marital property law with couples from the same state who were married before. Consistent with a simple model of household borrowing that trades off agency costs against risk sharing, the effect on investment was heterogeneous. It increased if most household property came from the husband and decreased if most came from the wife.

We show that New Keynesian models with frictionless labor supply face a challenge: given standard parameters, they cannot simultaneously match plausible estimates of marginal propensities to consume (MPCs), marginal propensities to earn (MPEs), and fiscal multipliers. A HANK model with sticky wages provides a solution to this trilemma.

Dutch-Caribbean plantations attracted substantial outside funding in the 1760s. This came to an abrupt end after the 1773 credit crisis. We use one banker’s detailed archives to analyze how bankers and investors were initially able to overcome asymmetric information problems, and why the system eventually broke down. Bankers oversaw plantations’ cash flows and placed debt with investors in the form of mortgage-backed securities. Strong growth led to lax screening and an oversupply of credit. After a fall in commodity prices, plantation debts were unsustainable. Restructurings were incomplete and debt overhang led to underinvestment and a drop in economic activity.
