We develop a model of stock valuation and optimal IPO timing when investment opportunities are time-varying. IPO waves in our model are caused by declines in expected returns, increases in expected profitability, or increases in prior uncertainty about average profitability. The model predicts...

This paper examines the economic environments in which past U.S. stock market booms occurred as a first step toward understanding how asset price booms come about and whether monetary policy should be used to defuse booms. We identify several episodes of sustained rapid rise in equity prices in...

We use a quantitative equilibrium model with houses, collateralized debt and foreign borrowing to study the impact of global imbalances on the U.S. economy in the 2000s. Our results suggest that the dynamics of foreign capital flows account for between one fourth and one third of the increase in...

To understand a price boom, it is helpful to take account of: (1) observable indicators of changes in ex ante risk tolerance, (2) what information exists and when, and (3) the incentives lenders face. This paper takes such an approach to the Florida land boom of the mid-1920s, the U.S.' first...

We study the joint evolution of prices and rents of residential property. After constructing rent and price indices for renter- and owner-occupied properties, we decompose the change in the price of occupant-owned property into (1) changes in rent, (2) changes in the relative prices of investor-...

The U.S. entrepreneurial finance market has changed dramatically over the last two decades. Entrepreneurs raising their first round of venture capital retain 30% more equity in their firm and are more likely to control their board of directors. Late-stage startups are raising larger amounts of...

This paper examines the hypothesis that non-U.S. firms cross-list in the United States to increase protection of their minority shareholders. Cross-listing on an organized exchange (NYSE or Nasdaq) in the U.S. subjects a non-U.S. firm to a number of provisions of U.S. securities law and requires...

We create a novel dataset to examine the nature and determinants of dual-class IPOs. We document that dual-class firms have different types of controlling shareholders and wedges between voting and economic rights. We find that the founders' wedge is largest when founders have stronger...

During the past two decades, there has been a dramatic change in IPO activity around the world. Though vibrant IPO activity, attributed to better institutions and governance, used to be a strength of the U.S., it no longer is. IPO activity in the U.S. has fallen compared to the rest of the world...
