In this paper, I estimate the effect of mandatory greenhouse gas (GHG) emissions disclosure on corporate value. Using the introduction of mandatory GHG emissions reporting for firms listed on the Main Market of the London Stock Exchange as a source of exogenous variation, I find that firms most...

We investigate how board overlap affects coordination and performance among public firms. Our identification exploits the staggered introduction of Corporate OpportunityWaivers (COWs) in nine U.S. states since 2000. By reducing legal risk to directors serving on multiple boards, the COW...

This article examines the recent regulatory developments with regard to short selling. Short selling regulation is an important factor in firm governance because it affects the way in which firms are subject to market discipline. We begin with a comprehensive compilation of emergency...

We examine the effects of mandatory ESG disclosure around the world using a novel dataset. Mandatory ESG disclosure increases the availability and quality of ESG reporting, especially among firms with low ESG performance. Mandatory ESG reporting has in turn beneficial effects on firm’s...

We analyze how the adoption of the California Consumer Protection Act (CCPA), which limits buying or selling consumer data, heterogeneously affects firms with and without previously gathered data on consumers. Exploiting a novel and hand-collected data set of 11,436 conversational-AI firms with...

Using properties of the cdf of a random variable defined as a saddle-type point of a real valued continuous stochastic process, we derive first-order asymptotic properties of tests for stochastic spanning w.r.t. a stochastic dominance relation. First, we define the concept of Markowitz...

We develop and implement methods for determining whether introducing new securities or relaxing investment constraints improves the investment opportunity set for prospect investors. We formulate a new testing procedure for prospect spanning for two nested portfolio sets based on subsampling and...

Much of the trading activity in Equity markets is directed to brokerage houses. In exchange they provide so-called quot;soft dollarsquot; which basically are amounts spent in quot;researchquot; for identifying profitable trading opportunities. Soft dollars represent about USD 1 out of every USD...
