Many reform proposals call for the creation of one or more health insurance exchanges, intermediaries that can help individuals or small employers navigate the insurance market. An exchange might be public or private, national or local. It might serve simply as a clearinghouse for plan information or could play an active role in setting benefit packages, choosing high-quality plans, and negotia...

Measuring soluble gas in the exhaled breath is a non-invasive technique used to estimate levels of respiratory, solvent, and metabolic gases. The interpretation of these measurements is based on the assumption that the measured gases exchange in the alveoli. While the respiratory gases have a low blood-solubility and exchange in the alveoli, high blood-soluble gases exchange in the airways. The...

Using both employer- and beneficiary-level data, we examined trends in employer-sponsored retiree health insurance and prospects for future coverage. We found that retiree health insurance has become less prevalent over the past decade, with firms reporting declines in the availability of coverage, and Medicare-eligible retirees reporting lower rates of enrollment. The future of retiree health ...

Insurance claim practices determine the extent to which insurers will or will not honor their promises. This Article describes the failure in the market for claim practices, the failure of the regulatory responses to that failure, and the ways in which litigation can provide a partial corrective.

Despite the growing adoption of decentralized exchanges, not much is yet known about their market quality. To shed light on this issue, we compare blockchain-based venues (DEX) to centralized crypto exchanges (CEX) by assessing two key aspects quality: price efficiency and liquidity. Using a novel comprehensive data set, find that overall CEX provide better quality but DEX become competitive fo...

We adopt the fixed node restricted path integral Monte Carlo method within "Worm algorithm" to simulate Wigner's Jellium model at finite, non zero, temperatures using free-particle nodes of density matrix. The new element is that we incorporate Worm algorithm paradigm Prokof'ev and Svistunov in grand canonical ensemble order more efficiently handle fermionic exchanges. present results for struc...
