This paper develops and applies a simple graphical approach to portfolio selection that accounts for covariance between asset returns and an investor's labor income. Our graphical approach easily handles income shocks that are partly hedgable, multiple risky assets, many periods and life cycle...

We study stock returns over the period of the global financial crisis of 2007-2008 and identify three crisis "shock factors" related to unique features of the crisis: (1) the collapse of global demand, (2) the contraction of credit supply, and (3) selling pressure on firms' equity. All three of...

This paper incorporates a time-varying intensity of disasters in the Rietz-Barro hypothesis that risk premia result from the possibility of rare, large disasters. During a disaster, an asset's fundamental value falls by a time-varying amount. This in turn generates time-varying risk premia and...

This paper uses micro-level data on mutual funds from different financial centers investing in equity and bonds to study how investors and managers behave and transmit shocks across countries. The paper finds that the volatility of mutual fund investments is driven quantitatively by both the...

We introduce dynamic incentive contracts into a model of unemployment dynamics and present three results. First, wage cyclicality from incentives does not dampen unemployment dynamics: the response of unemployment to shocks is first-order equivalent in an economy with flexible incentive pay and...

We study the nature of systemic sovereign credit risk using CDS spreads for the U.S. Treasury, individual U.S. states, and major European countries. Using a multifactor affine framework that allows for both systemic and sovereign-specific credit shocks, we find that there is considerable...

Global risk and risk aversion shocks have distinct distributional impacts on emerging market capital flows and returns. In particular, we find salient consequences of these different global shocks for tail risk in emerging markets. Open-end mutual fund trading provides a key mechanism linking...

We characterize how risk evolves during a crisis. Using high-frequency data, we find that the first two principal components (PCs) of the covariance matrix of global asset returns experience large, sudden, and temporary spikes coinciding with well-known crises - Covid-19 pandemic, Global...

Governments are present-biased toward spending. Fiscal rules are deficit limits that trade off commitment to not overspend and flexibility to react to shocks. We compare coordinated rules - chosen jointly by a group of countries - to uncoordinated rules. If governments' present bias is small,...
