In order to define strategies to curb the continuing increase in healthcare costs, we describe the cost breakdown of open tibial fractures. Twenty-seven clinical and process variables were recorded retrospectively, and five main hospital related cost categories were defined. Three multivariate linear models were fitted to the data. Total healthcare costs of open tibial fractures were almost twi...

Although carp is still widely sold and used in its fresh form, a range of value additions may also be observed. It is essential to know the development and management of a carp farm production costs and their evolution. In Iran, warm-water fish farming is based on common, silver, grass, and bighead carps. The carp is easy to rise in hatcheries in very large numbers at little cost, and is distri...

BACKGROUND The number of septic total hip arthroplasty (THA) revisions is increasing continuously, placing a growing financial burden on hospitals. Orthopedic departments performing septic THA revisions have no basis for decision making regarding resource allocation as the costs of this procedure for the departments are unknown. It is widely assumed that septic THA procedures can only be perfor...

Efforts to control medical care costs depend critically on how individuals respond to prices. I estimate the price elasticity of expenditure on medical care using a censored quantile instrumental variable (CQIV) estimator. CQIV allows estimates to vary across the conditional expenditure distribution, relaxes traditional censored model assumptions, and addresses endogeneity with an instrumental ...

Beginning with Anderson, Banker and Janakiraman (2003), the accounting literature attributes the asymmetric cost response to activity changes or sticky costs as resulting from managerial choices. Using a simulated dataset that excludes any role for managerial actions, we investigate whether cost structure alone could yield regression estimates similar to those the literature interprets as consi...

In Part I of this paper the development of allocated and incremental cost and revenue techniques was described. have become predominant. In contrast, methodologies for dealing with revenues, particularly incremental measures, are in their infancy. Part II of the paper describes the state-of-the-art for these methods. This review is explicitly not meant as a cookbook of methodology, and the read...

The impact of installing process control systems can be expected in terms of performance improvements through reduced operating costs.  Since these installations impose considerable capital expenditure, the profitability of the new systems should be economically justified. Controlled variable trend was reconstructed by a combination of simple waves, which provided a means to simulate the ef...

Economic impacts of agricultural carbon sequestration involve direct costs of sequestration management adoption as well as a variety of indirect costs and benefits. The nature and significance of these impacts are discussed. Spatial and temporal heterogeneity in agriculture is identified as an influential factor. Techniques to estimate the cost of agricultural carbon sequestration are briefly r...

  We consider the maximal covering location-allocation problem with multiple servers. The objective is to maximize the population covered, subject to constraints on the number of service centers, total number of servers in all centers, and the average waiting time at each center. Each center operates as an M/M/k queuing system with variable number of servers. The total costs of establishing cen...

Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...
