We study a model of portfolio choice, in which housing prices are predictable and adjustment costs must be paid when there is a housing transaction. We show that two state variables affect the agent's decisions: (i) his wealth-house ratio; and (ii) the time-varying expected growth rate of...

We generalize the classic Grossman and Laroque (1990) (GL) model of optimal portfolio choice with housing and transaction costs by introducing predictability in house prices. As in the GL model, agents only move to more expensive (cheaper) houses when their wealth-to-housing ratios reach an...

The pro-cyclical effect of bank capital requirements has attracted much attention in the post-crisis discussion of how to make the financial system more stable. This paper investigates and calibrates a dynamic provision as an instrument for addressing pro-cyclicality. The model for the dynamic...

We assess the role of banks in the Paycheck Protection Program (PPP), a large and unprecedented smallbusiness support program instituted as a response to the COVID-19 crisis in the United States. In 2020, the PPP administered more than $525 billion in loans and grants to small businesses through...

The Paycheck Protection Program (PPP) was a large and unprecedented small-business support program that allocated $800 billion in loans and grants to small businesses following the onset of the COVID-19 crisis. This paper explores the optimal allocation of funds across firms and the distortions...
