articleOpen accessSenior authorAbstract A fiduciary of a charity has a fundamental duty to act in good faith and in a manner the fiduciary reasonably believes to be in the best interests of the charity in light of its purposes. In theory, this duty of loyalty seems uncomplicated and, in simple cases, it often is. In practice, for many fiduciaries discerning the content of the duty of loyalty, and sometimes even identifying the charity and the legal purposes to which the duty is owed, is not in fact so simple. Challenges to identifying and complying with fiduciary duties can arise when board members serve a charity because they reflect the experiences of certain constituencies or identities. Examples abound. University boards, for instance, have long included members who are students, union members, or other stakeholder representatives. Complications related to intersecting entities can also muddle understanding of a fiduciary’s responsibilities. In this Article we offer a brief examination of the complications raised by various forms of constituency memberships, the ways in which fiduciary law attempts to clarify duties, and some tentative suggestions to ameliorate confusion regarding these duties.

National Bureau of Economic Research · 2025-10-01
reportOpen accessCertificate of Need (CON) laws regulate entry and capital investments in healthcare with the goal of containing costs while preserving access and quality.This paper examines the relationship between these laws and overall mortality as well as leading causes of mortality: cancer and cardiovascular disease.Using county-level death records, we conducted an event-study analysis comparing mortality rates in states that repealed their CON laws to states that did not between 1979 and 2004.The repeal of CON laws was associated with short-run reductions in cancer mortality, primarily from reductions in lung cancer mortality.Cardiovascular mortality and allcause mortality rates were unchanged.

reportOpen access1st authorCorrespondingEstimates of the impact of Certificate of Need laws on medical care have been inconsistent, possibly because not all CON laws apply to all services.Using an original dataset identifying imaging-related CON laws, we estimate the effects of CON on CT and MRI, using regression discontinuities at state borders.Medicare beneficiaries in regulated states are slightly less likely to receive any image and considerably less likely to receive low-value imaging than beneficiaries in non-regulated states.High-value imaging is either unaffected or declines much less.Overall, CON reduces low value care and largely leaves high value care unaffected.
