Economic Consequences Of Public Pension Accounting Regulation Changes: Evidence From Housing Markets And Local Economies, Grace Haoqing Fan

Research Collection School Of Accountancy

I examine whether, and through which channels, government pension accounting regulations affect local housing markets and economies. Using both a contiguous border-county approach across multiple states and a single-state study in California, I find that regions exposed to more severe state-level pension underfunding experience lower housing market growth after the introduction of Government Accounting Standards Board (GASB) regulations 67 and 68, which significantly enhance the transparency of public pension underfunding. The effect is more pronounced in states heavily impacted by the new regulations and in counties more reliant on state funding. Further analyses suggest that the observed effect is driven …

Alabama’S Ivf Immunity Law: A Constitutional License To Kill?, Dani Wasshausen

Washington and Lee Law Review

In today’s post-Dobbs world, states may freely define fetal “persons” and those fundamental rights afforded to them, but not without consequence. The Supreme Court of Alabama’s groundbreaking decision in LePage v. Center for Reproductive Medicine, P.C., holding that frozen embryos are “children” under the Wrongful Death of a Minor Act, led fertility clinics and services across the state to close. These in vitro fertilization (IVF) providers feared liability exposure because their standard practices—including embryonic fertilization, testing, cryopreservation, and transfer—inevitably result in damage or death to embryos. The Alabama Legislature swiftly responded by enacting a law granting broad civil and criminal …
