This paper develops a general equilibrium model to examine the quantitative effects of speculative bubbles on capital accumulation, growth, and welfare. A near-rational bubble component in the model equity price generates excess volatility in response to observed technology shocks. In...

This paper examines the asset pricing implications of nominal rigidities. Firms that adjust their product prices infrequently earn a return premium of 4% per year. Merging unique product-price data at the firm level with stock returns, I document that the premium for sticky-price firms is a...

This paper examines the asset-pricing implications of nominal rigidities. I find that firms that adjust their product prices infrequently earn a cross-sectional return premium of more than 4% per year. Merging confidential product price data at the firm level with stock returns, I document that...

This paper derives explicitly an equity pricing relationship in a New Keynesian model. This relationship is used to study the equity pricing implications of New Keynesian models. I find that New Keynesian models suffer from the same asset pricing shortcomings as more traditional RBC versions....

We find that equity mispricing impacts the speed at which firms adjust to their target leverage and does so in predictable ways depending on whether the firm is over- or underlevered. For example, firms that are above their target leverage and should therefore issue equity (or retire debt),...

We use the forward-looking information from the US and global capital markets to estimate the economic impact of global warming, specifically, long-run temperature shifts. We find that global warming carries a positive risk premium that increases with the level of temperature and that has almost...

Portfolio managers’ orders trade off return and trading cost predictions. Return predictions rely on alpha models, whereas price impact models quantify trading costs. This paper studies what happens when trades are based on an incorrect price impact model, so that the portfolio either over- or...
