Early Detection of Amyloid β Pathology in Alzheimer's Disease by Molecular MRI.

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia. Early stage β-amyloid oligomers (AβOs) and late stage Aβ plaques are the pathological hallmarks of AD brains. AβOs are known to be more neurotoxic and contribute to neuronal damage.

What to expect when you are expecting: Are health care consumers forward-looking?

A fundamental question in health insurance markets is how do health care consumers dynamically optimize their medical utilization under non-linear insurance contracts? Our paper tests the neoclassical prediction that a fully forward-looking agent only responds to their expected end-of-year price. Our unique identification strategy studies families during the year of childbirth who will likely satisfy their annual deductible, thereby knowing their expected end-of-year price. We find that during the year of a childbirth, fathers increase medical spending by 11% per month after their deductible is satisfied, rejecting the null of fully forward-looking consumers.
