Audit Fees In Family Firms: Evidence From U.S. Listed Companies

Family businesses are an important part of the world economy (Anderson & Reeb, 2003) and differ considerably from non-family firms with regard to corporate governance. However, despite their difference, family businesses have received relatively little research attention. Our study contributes to this growing research by empirically investigating the relationship between family shareholding and audit pricing. Using a sample of 3,291 firm-year observations of major U.S. listed companies, for the 20062008 period, our results demonstrate that audit fees are negatively associated with family shareholding after taking into account time-varying effects and industry effects as well as traditional control variables. The empirical results are robust to alternative family shareholding measures and estimation model specifications. Our results are consistent with the convergence-of-interests hypothesis suggesting that family firms face lower manager/shareholders agency costs. Auditors charge lower fees for family firms because of lower information asymmetry and risk given that the controlling family is well informed about the firm and is better able to monitor managerial decisions

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
