Abstract This paper develops a novel dataset of weekly economic conditions indices for the 50 U.S. states going back to 1987 based on mixed-frequency dynamic factor models with weekly, monthly, and quarterly variables that cover multiple dimensions state economies. We find considerable cross-state heterogeneity in length, depth, timing business cycles. illustrate usefulness these state-level qu...

Abstract We evaluate alternative indicators of global economic activity and other market fundamentals in terms their usefulness for forecasting real oil prices petroleum consumption. World industrial production is one the most useful indicators. However, by combining measures from several different sources, we can do even better. Our analysis results a new index conditions assessing future ener...

Previous work has studied the classical joint economic lot size model as an adverse selection problem with asymmetric cost information. Solving this problem is challenging due to the presence of countervailing incentives and two-dimensional information asymmetry, under which the classical single-crossing condition does not need to hold. In the present work we advance the existing knowledge abou...

Increased attention has been paid recently to the issue of the regulation of professional boundaries. In this paper, we undertake an international comparison of the regulation of health professional boundaries across the OECD countries of Canada, the U.S., the U.K. and Australia. Our case studies focus on the inter-professional boundary negotiation between medicine and nursing and the intra-pro...

The correlated demand caused by cross-selling, Zhang et al (2011) proposed a two-item EOQ model, where the unmet demand for the major item can be partially backordered with lost sales that will reduce demand for the minor item. They developed an enumeration algorithm that can deal with only one minor associated item. Zhang et al (2011) proposed the partial backordering EOQ with correlated deman...

The results of a cost-effectiveness analysis of cervical cancer screening in The Netherlands are reported, emphasizing the analysis of the costs of screening and consequent diagnosis and treatment. Many organized screening policies are evaluated, differing in age-range and interval between screens. The cost estimates are based on organization charts, file studies and tariffs. The costs of scree...
