We propose implied spreads (IS) and normalized implied spreads (NIS) as simple measures to characterize option prices. IS is the credit spread of an option's implied bond, the portfolio long a risk-free bond and short a put option. NIS normalizes IS by the risk-neutral default probability and...

We present a novel empirical benchmark for analyzing credit risk using “pseudo firms” that purchase traded assets financed with equity and zero-coupon bonds. By no-arbitrage, pseudo bonds are equivalent to Treasuries minus put options on pseudo-firm assets. Empirically, like corporate...

Many stylized facts of leverage, trading, and asset prices obtain in a frictionless general equilibrium model that features agents' heterogeneity in endowments and habit preferences. Our model predicts that aggregate debt increases in expansions when asset prices are high, volatility is low, and...

We calculate the costs and benefits of the largest ever U.S. Government intervention in the financial sector announced the 2008 Columbus-day weekend. We estimate that this intervention increased the value of banks' financial claims by $131 billion at a taxpayers' cost of $25 -$47 billions with a...

Motivated by the recent rise of populism in western democracies, we develop a tractable equilibrium model in which a populist backlash emerges endogenously in a strong economy. In the model, voters dislike inequality, especially the high consumption of ``elites." Economic growth exacerbates...

We develop a model of political cycles driven by time-varying risk aversion. Agents choose to work in the public or private sector and to vote Democrat or Republican. In equilibrium, when risk aversion is high, agents elect Democrats---the party promising more redistribution. The model predicts...

We develop a simple general equilibrium model with heterogeneous agents, incomplete financial markets, and redistributive taxation. Agents differ in both skill and risk aversion. In equilibrium, agents become entrepreneurs if their skill is sufficiently high or risk aversion sufficiently low....
