In this paper, we study Demand Response (DR) problematics for different levels of information sharing in a smart grid. We propose a dynamic pricing scheme incentivizing consumers to achieve an aggregate load profile suitable for utilities, and study how close they can get to an ideal flat aggregate demand profile depending on how much information they share. When customers can share all their l...

BACKGROUND Crack pipe sharing can increase health risks among people who use drugs, yet the reasons for sharing these pipes have not been well described. Therefore, we sought to identify the prevalence and correlates of crack pipe sharing among a community-recruited sample of people who use illicit drugs in Vancouver, a setting where crack pipes are provided at low or no cost. FINDINGS Data f...

BACKGROUND Effective treatment for chronic diseases often requires medication refill persistence. Health plans have frequently increased the amount of member cost-sharing by implementing tier-copayment pharmacy benefit designs and raising copayments. However, increased member costshare may present a barrier to the management of chronic conditions. Little is known about the relationship between ...

background measures taken over the past four years in greece to reduce pharmaceutical expenditure have led to significant price reductions for medicines, but have also changed patient cost-sharing rates for prescription drugs. this study attempts to capture the resulting increase in patients’ out-of-pocket (oop) expenses for prescription drugs during the 2011-2014 period.   methods the authors ...

OBJECTIVES Specialty drugs often offer medical advances but are frequently subject to high cost sharing. This is particularly true with Medicare Part D, where after meeting a deductible, patients without low-income subsidies (non-LIS) typically face 25% to 33% coinsurance (initial coverage phase with "specialty tier" cost sharing), followed by ~50% coinsurance (coverage gap phase), and then 5% ...

The members of a chain always try to find new ways in order to raise their profit. Hence we intend to study two different scenarios in a single item two-echelon green supply chain including two manufacturers and one retailer to study the effects of two effective contracts on members’ profit. Two scenarios are discussed and in first one, first manufacturer proposes quantity discount contract to ...

BACKGROUND In January 1997, reference pricing for angiotensin-converting-enzyme (ACE) inhibitors for patients 65 years of age or older was introduced in British Columbia, Canada. For medications within a specific class, insurance covers the cost up to the reference price, and patients pay the extra cost of more expensive medications. Although reference pricing may reduce the costs of prescripti...

Ride-sharing or vehicle-pooling allows commuters to team up spontaneously for transportation cost sharing. This has become a popular trend in the emerging paradigm of sharing economy. One crucial component support effective ride-sharing is matching mechanism that pairs suitable commuters. Traditionally, been performed centralized manner, whereby an operator arranges according global objective (...

Physicians, health plans, and health systems are increasingly evaluated and rewarded based on Health Plan Effectiveness Data and Information Set (HEDIS) and HEDIS-like performance measures. Concurrently, employers and health plans continue to try to control expenditures by increasing out-of-pocket costs for patients. The authors use fixed-effect logit models to assess how rising copayment rates...
