This short paper shows how excess global saving led to asset price inflation in U.S. stocks during 1981 to 2019. It compares stock PE ratios to corporate bond values to explain that investor exuberance for stocks enabled and enhanced the extent of the secular stock rise

We study firm-level characteristics that a manager would employ as signalling tools in order to time the market (i.e. repurchases and issues). Following the market timing framework, we develop a two-factor asset pricing model comprising a “market” and a “mispricing” factor, which is able...

What determines risk-bearing capacity and the amount of leverage in financial markets? Using unique archival data on collateralized lending, we show that personal experience can affect individual risk-taking and aggregate leverage. When an investor syndicate speculating in Amsterdam in 1772 went...

This paper develops a tractable asset pricing framework based on an Arrow Debreu economy with heterogeneous agents. The assumption of heterogeneity recasts the market rather than aggregate consumption as the key element for pricing securities. The model expresses some asset pricing relationships...

The basic paradigm of asset pricing is in vibrant flux. The purely rational approach is being subsumed by a broader approach based upon the psychology of investors. In this approach, security expected returns are determined by both risk and misvaluation. This survey sketches a framework for...

We study the implications of undiversified investors in a production-based asset pricing model with rare disasters. In our model, households experience idiosyncratic shocks to human capital and partially invest their wealth in a single firm with idiosyncratic shocks. The model features tractable...

We study sources and implications of undiversified portfolios in a production-based asset pricing model with financial frictions. Households take concentrated positions in a single firm exposed to idiosyncratic shocks because managerial effort requires equity stakes, and because investors gain...

In this paper, we examine the economic value of a text-based measure of financial integration. Our attention measure of financial integration is a strong positive predictor of currency excess returns. Specifically, the financial integration measure is positively priced in the cross-section of...

We study the dynamics of a Lucas-tree model with finitely lived agents who "learn from experience." Individuals update expectations by Bayesian learning based on observations from their own lifetimes. In this model, the stock price exhibits stochastic boom-and-bust fluctuations around the...
