Building on recent developments in behavioral asset pricing, we develop a model in which an increase in the dispersion of investor beliefs under short-selling constraints predicts a "bubble," or a rise in a stock's price above its fundamental value. Our model predicts that managers respond to...

We use firm-level financial data to illustrate the impact of the COVID-19 crisis under several scenarios. We estimate COVID-19 induced cumulative net revenue losses for EU companies in the range of 5.4 to 10.0% of total assets, depending on the strength of the policy support and length of the...

We investigate the cost of capital in a model with an agency conflict between inside managers and outside shareholders. Inside ownership reflects the classic tradeoff between incentives and risk diversification, and the severity of agency costs depends on a parameter representing investor...

A detailed treatment of aggregation and capital heterogeneity substantially improves the performance of the investment CAPM. Firm-level predicted returns are constructed from firm-level accounting variables and aggregated to the portfolio level to match with portfolio-level stock returns....

The q-factor model shows strong explanatory power and largely summarizes the cross section of average stock returns. In particular, the q-factor model fully subsumes the Fama-French (2018) 6-factor model in head-to-head factor spanning tests. The q-factor model is an empirical implementation of...

Empirical evidence suggests that capital structure varies across firms facing different levels of information asymmetry, however, this evidence contradict the prediction of pecking order hypothesis. Although debt capacity constraints offer some explanation for this discrepancy, it fails to...

We study the effects of monetary-policy-induced changes in Tobin's q on corporate investment and capital structure. We develop a theory of the mechanism, provide empirical evidence, evaluate the ability of the quantitative theory to match the evidence, and quantify the relevance for monetary...

This paper considers the effect of corruption on the effciency of capital investment. Using firm-level level data from the World Bank enterprise surveys, covering 90 developing and transition economies, we consider whether the cost of informal bribe payments distorts the efficient allocation of...

In this paper we study a continuous time, optimal stochastic investment problem under limited resources in a market with N firms. The investment processes are subject to a time-dependent stochastic constraint. Rather than using a dynamic programming approach, we exploit the concavity of the...

Private investment in advanced economies contracted sharply during the most recent financial crisis. Using firm-level data from Denmark, this paper argues that the high leverage, which was build up by some firms before the crisis, contributed to the reduction in investment during the crisis, in...
