We study the cyclical effects of the timing of durable goods purchases in a general equilibrium model in which both durable and non-durable goods are consumed and the durable good is lumpy. At the microeconomic level, the timing of durable goods purchases supplies some insulation for non-durable consumption over the cycle. At the macroeconomic level, the timing decisions tend to amplify and propagate wealth and income shocks. Our model also allows for endogenous price determination. When the price of the durable changes due to inflexibility of workers between sectors, the effect of adverse shocks is even stronger and longer. 相似文献

Hospitals designed using the concepts of architect Gordon Friesen are especially conducive to reengineering for patient-focused care. The Nurserver, a closet-like space outside each patient's room, makes it very easy for hospitals to redesign their methods for delivering supplies so that caregivers seldom have to go more than a few feet to get what they need. In this article, staff of Monongalia General Hospital in Morgantown, West Virginia, describe how they have used the Friesen design to modify supply distribution processes. 相似文献

An analysis of the way in which primary age children design, particularly when working with a professional designer, suggests that there are several similarities in approach between the two. This observation is supported by evidence from developmental psychology, which has stressed the crucial role which play performs in developing children's inventiveness and ability to solve problems. Subsequent research focusing on children's designing suggests that this play is fundamental to designing activity, and extends naturally into the more formalised activities of drawing and modelling. Through playing and using narrative language to describe their actions, children are learning to interpret their own mental images. To develop these images and make them more concrete children use their hands in drawing and modelling whilst drawing on their accumulated personal knowledge about the activity of designing, in a similar way to that in which professional designers make use of their own, highly sophisticated skills to bring an idea to concrete fruition. By comparison with some of the rigid models of the design process described in schools, designers and children may have more in common than we realise. 相似文献

People don't like change. That includes materiel managers, administrators, and clinical providers. Managed competition or managed care will work if, and only if, the American professions and the American public recognize the value of highly educated and qualified clinical and nonclinical providers and if the health care industry responds in kind. 相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling 总被引:1,自引:0,他引:1
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework. 相似文献

We examine the introduction of the Actual Size Rule (ASR) on Nasdaq during a control period and a period of market stress.
We find that market makers in both ASR and Non-ASR stocks reduce quotation sizes and widen spreads when under stress but the
reduction of quotation size and increase in spread width are significantly larger for ASR stocks. We also examine October
27, when the market was under the most severe stress. We find ASR and Non-ASR stocks have similar reductions in time-weighted
quotation ask size when compared with the control sample but ASR bid sizes are about 10% smaller than Non-ASR bid sizes. Our
findings imply that the ASR rule may significantly reduce market quality under times of market stress.
