We test how market overvaluation affects corporate innovation. Estimated stock overvaluation is very strongly associated with measures of innovative inventiveness (novelty, originality, and scope), as well as R&D and innovative output (patent and citation counts). Misvaluation affects R&D more...

Psychological evidence indicates that decision quality declines after an extensive session of decision-making, a phenomenon known as decision fatigue. We study whether decision fatigue affects analysts' judgments. Analysts cover multiple firms and often issue several forecasts in a single day....

Ambiguity aversion alone does not explain the market nonparticipation puzzle. We show that in a rational expectations equilibrium model with a fund offering the risk-adjusted market portfolio (RAMP), ambiguity averse investors hold the fund and an information-based portfolio, and thus...

This paper proposes a robust one-pass estimator that is easy to code: Justified by the market-model itself and using a prior that market-betas should not be less than –2 and more than +4, the market-model is run on daily stock rates of return that have first been winsorized at –2 and +4...

Contrary to common perception, many fixed-income investors have not suffered unusually low real interest rates in and after the Great Recession of 2008. This is because taxable investors must first pay taxes on nominal interest returns, before inflation further reduces their earned real interest...

Do financial markets properly reflect leverage? Unlike Gomes and Schmid (2010) who examine this question with a structural approach (using long-term monthly stock characteristics), my paper examines it with a quasi-experimental approach (using short-term a discrete event). After a firm has...

This paper compares investor sentiment measures based on consumer confidence surveys with measures extracted from the closed-end fund discount (CEFD). Our evidence suggests that these two kinds of sentiment measures do not correlate well with one another. For a short 2 - 4 year period in which...

Given the historically high equity premium, is it now a good time to invest in the stock market? Economists have suggested a whole range of variables that investors could or should use to predict: dividend price ratios, dividend yields, earnings-price ratios, dividend payout ratios, net issuing...

We review the theory and evidence on IPO activity: why firms go public, why they reward first-day investors with considerable underpricing, and how IPOs perform in the long run. Our perspective on the literature is three-fold: First, we believe that many IPO phenomena are not stationary. Second,...

Our paper reexamines the forecasting regressions which predict annual aggregate stock market returns net of the risk-free rate with lagged aggregate dividend-yield ratios and dividend-price ratios. Prior to 1990, the conditional dividend yield could reliably outperform the historical equity...
