Conventional optimal design frameworks consider a narrow range of sampling cost structures that thereby constrict their capacity to identify the most powerful and efficient designs. We relax several constraints of previous optimal design frameworks by allowing for variable sampling costs in cluster-randomized trials. The proposed framework introduces additional design considerations and has the potential to identify designs with more statistical power, even when some parameters are constrained due to immutable practical concerns. The results also suggest that the gains in efficiency introduced through the expanded framework are fairly robust to misspecifications of the expanded cost structure and concomitant design parameters (e.g., intraclass correlation coefficient). The proposed framework is implemented in the R package odr.

Engineers, policy makers, and managers have shown increasing interest in increasing the sustainability of products over their complete lifecycles and also from the ‘cradle to grave’ or from production to the disposal of each specific product. However, a significant amount of material is disposed of in landfills rather than being reused in some form. A sizeable proportion of the products being dumped in landfills consist of packaging materials for consumable products. Technological advances in plastics, packaging, cleaning, logistics, and new environmental awareness and understanding may have altered the cost structures surrounding the lifecycle use and disposal costs of many materials and products resulting in different cost-benefit trade-offs. An explicit and well-informed economic analysis of reusing certain containers might change current practices and results in significantly less waste disposal in landfills and in less consumption of resources for manufacturing packaging materials. This work presents a method for calculating the costs associated with a complete process of implementing a system to reuse plastic containers for food products. Specifically, the different relative costs of using a container and then either disposing of it in a landfill, recycling the material, or reconditioning the container for reuse and then reusing it are compared explicitly. Specific numbers and values are calculated for the case of plastic milk bottles to demonstrate the complicated interactions and the feasibility of such a strategy.

ABSTRACT This paper extends prior literature on cost behavior by providing insights into how firms achieve changes to cost structure in response to two important risk drivers, i.e., demand uncertainty and financial risk. Using theory from labor economics, supply-chain management, and finance, we posit that demand uncertainty and financial risk influence cost management activities. Specifically, we argue that firms are likely to alter resource procurement choices to increase cost elasticity in response to these two risk drivers. We use data from California hospitals that allow for the calibration of three distinct resource procurement choices that increase cost elasticity: outsourcing, leasing of equipment, and hiring contract labor. Mediation analysis using 2,202 hospital year observations indicates that both demand uncertainty and financial risk influence cost elasticity. Importantly, these effects are mediated by the three aforementioned resource procurement choices. Overall, our findings support the view that firms make procurement choices to manage the risk associated with cost structures.

The Patient Protection and Affordable Care Act (ACA) provided for cost savings in the Medicare program, in part to underwrite coverage expansion to Medicare beneficiaries, to finance new coverage for those not eligible for Medicare, and to strengthen Medicare’s financial outlook. One cost-saving measure, a reformulation and reduction in payments to private health insurance plans that provide Medicare benefits through the Medicare Advantage (MA) program, had a sound policy basis but was criticized, particularly by opponents of the ACA, as a measure that would lead to increased costs, reductions in benefits, and diminished plan choices to Medicare beneficiaries enrolled in MA plans. Despite dire predictions to this effect, a review of a sample of MA plan offerings in New York State in 2012 shows that Medicare beneficiaries enrolled in such plans did not experience significant benefit reductions or increased costs. While the number of plan offerings decreased, the reduction was mostly caused by the elimination of duplicative plan choices in 2011. Although the MA plan executives we interviewed indicated that further reductions in plan reimbursement in future years—tempered by potential bonus payments for meeting quality and performance metrics—could impact plan costs and benefits, they believed plans will employ a number of strategies to remain in the market and maintain beneficiary benefits and cost structures. However, government regulators and consumer advocates will need to examine MA plan offerings in the coming years to determine the effect of plan reaction to the ACA payments on beneficiaries’ costs for coverage and access to care.

This chapter will examine emerging new norms across higher education in the United States following the recession of 2008-09. Colleges and universities face an environment increasingly made up of prospective students and their families shopping and bargaining for the best college deal; institutions are struggling to control student costs by raising discount rates; administrators are seeking to find new sources of revenue and programmatic niches; and faculty are increasingly focused on how to make their curriculum more unique and relevant. Finally, higher education leaders should closely examine long-held recruitment and financial aid strategies, cost structures, academic calendars and mission to meet the new situation. This chapter will summarize the development of the new landscape in public and private higher education, including the growing similarities facing public and private institutions including their common efforts to keep higher education affordable and accessible, and conclude with recommendations for administrators as they navigate their way through the new norm.
