ABSTRACT The gold standard in the sciences is uncovering causal relationships. A growing literature in economics utilizes field experiments as a methodology to establish causality between variables. Taking lessons from the economics literature, this study provides an “A‐to‐Z” description of how to conduct field experiments in accounting and finance. We begin by providing a user's guide into what a field experiment is, what behavioral parameters field experiments identify, and how to efficiently generate and analyze experimental data. We then provide a discussion of extant field experiments that touch on important issues in accounting and finance, and we also review areas that have ample opportunities for future field experimental explorations. We conclude that the time is ripe for field experimentation to deepen our understanding of important issues in accounting and finance.

We compare the payout policies of US industrials and banks over the past 30 years to better understand dividends, especially for banks. For industrials, dividends grow strongly after 2002, when the declining propensity to pay reverses. Banks have a higher and more stable propensity to pay dividends and resist cutting dividends as the 2007–2008 financial crisis begins. Before the crisis, increases in repurchases push payouts to historic levels. These findings are broadly consistent with the idea that banks use dividends to signal financial strength while agency costs of free cash flow better explain industrial payouts.

We examine the real effects of mandatory social-responsibility disclosures, which require SEC-registered mine owners to include their mine-safety records in their financial reports. These safety records are already publicly available elsewhere, which allows us to isolate and estimate the incremental real effects of including this information in financial reports. Comparing mines owned by SEC-registered issuers with mines that are not, we document that including safety records in financial reports decreases mining-related citations and injuries, and reduces labor productivity. Evidence from stock-market reactions and mutual-fund holdings suggests that increased awareness of safety issues is a likely explanation for the observed real effects.
