We review theory and evidence relating to herd behavior, payoff and reputational interactions, social learning, and informational cascades in capital markets. We offer a simple taxonomy of effects, and evaluate how alternative theories may help explain evidence on the behavior of investors,...

A larger CEO network can reduce the cost of equity by reducing information asymmetry between the firm and outsiders, and by increasing trust between the firm and stakeholders. Alternatively, a larger CEO network can increase the cost of equity because higher CEO connectedness encourages greater...

This paper tests the hypothesis that irrational market misvaluation affects firms' takeover behavior. We employ two contemporaneous proxies for market misvaluation, pre-takeover book/price ratios and pre-takeover ratios of residual income model value to price. Misvaluation of bidders and targets...

This article studies the most important legislative and shareholder boycott to date, the boycott of South Africa's apartheid regime. We find that corporate involvement with South Africa was so small that the announcement of legislative/shareholder pressure or voluntary corporate divestment from...

Using options- and press-based proxies for CEO overconfidence (Malmendier and Tate 2005a, 2005b, 2008), we find that over the 1993-2003 period, firms with overconfident CEOs have greater return volatility, invest more in innovation, obtain more patents and patent citations, and achieve greater...

We test whether and how equity overvaluation affects corporate financing decisions using an ex ante misvaluation measure that filters firm scale and growth prospects from market price. We find that equity issuance and total financing increase with equity overvaluation; but only among overvalued...
