This chapter examines, from a traditional perspective, several areas where the Securities and Exchange Commission (SEC) has impacted corporate governance in a meaningful way. By way of example, these subjects include insider trading, qualitative materiality, the role of gatekeepers (such as outside directors, attorneys, and accountants), the Commission’s use of disclosure to influence conduct, the implementation by subject companies of undertakings pursuant to SEC enforcement proceedings, and mergers and acquisitions (including tender offers and going-private transactions). This chapter’s focus is on the manner in which the SEC for well over 50 years has impacted corporate governance by means of exercising its rule-making and oversight authority.

We propose a new nonparametric technique to estimate the call function based on the superhedging principle. This approach requires minimal assumptions on absence of arbitrage and other market imperfections. The estimates so obtained are then combined with SNP estimates of the actual density of market returns. This permits to investigate the time behavior of the relative distance between the two densities obtained. Our empirical findings suggest that the more the two densities differ, the shorter is time to maturity, suggesting a major role of uncertainty over shorter than longer horizons.

We study how investor sentiment affects stock prices around the world. Relying on households’ Google search behavior, we construct a weekly measure of sentiment for 38 countries during 2004–2014. We validate the sentiment index in tests using sports outcomes and show that the sentiment measure is a contrarian predictor of country-level market returns. Furthermore, we document an important role of global sentiment in stock markets.
