AbstractAims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States.Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies.Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $16.2 M for the IDN and $3.3 M for the payer. The incremental savings per-person-per-month were $0.14 and $0.03 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings.Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed.Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years. 相似文献

State agencies and private historical organizations frequently acquire historical sites with unknown characteristics. In this
paper, we provide two approaches to evaluating the preservation decision. In the first approach, we show that a historical
site which is not permanently preserved provides citizens with a certain flexibility whose value can be measured as an option
on the maximum between the current real estate value and the preservation value. In the second approach, we assume that the
organization has an infinite planning horizon and chooses the optimal sale date. Using a contingent valuation estimate of
the public's willingness to pay for preservation of a specific historical site and the real estate price, we provide simulation
values of the preservation option value and the optimal stopping rule. 相似文献

A number of chronic poverty measures are now empirically applied to quantify the prevalence and intensity of chronic poverty, vis‐à‐vis transient experiences, using panel data. Welfare trajectories over time are assessed in order to identify the chronically poor and distinguish them from the non‐poor, or the transiently poor, and assess the extent and intensity of intertemporal poverty. We examine the implications of measurement error in the welfare outcome for some popular discontinuous chronic poverty measures, and propose corrections to these measures that seeks to minimize the consequences of measurement error. The approach is based on a novel criterion for the identification of chronic poverty that draws on fuzzy set theory. We illustrate the empirical relevance of the approach with a panel dataset from rural Ethiopia and some simulations. 相似文献

Industrial policy in any economy has a number of varying and occasionally conflicting objectives, but the overarching intention of the various grants, subsidies and support schemes, arguably, must be to improve the economic performance of the plants they assist directly. However, in the absence of counterfactual evidence, whether or not assistance does improve performance is hard to establish. In this paper, we consider the impact of two UK government industrial support schemes (Regional Selective Assistance and the Small Firm Merit Awards for Research and Technology) on UK manufacturing plant level total factor productivity in an attempt to answer the question, ‘did assistance make a difference?’ 相似文献

HOW DO SPOUSES SHARE THEIR FULL INCOME? IDENTIFICATION OF THE SHARING RULE USING SELF‐REPORTED INCOME 总被引:1,自引:0,他引:1
by Ekaterina Kalugina Natalia Radtchenko Catherine Sofer 《Review of Income and Wealth》2009,55(2):360-391
The paper applies the collective model to the analysis of intra-household inequality using one of the subjective-qualitative questions available in the RLMS (Russia Longitudinal Monitoring Survey) data, and provides a test for its assumptions. Interpreting the individual answers as reported budget scales we assume a correspondence between the budget level that household members report and their true income sharing. We first show that this assumption is supported by the data, and then use couples who report the same level of budget to identify the full sharing rule for the whole sample. 相似文献

In regression analysis, classical estimations may be excessively influenced by a few atypical observations. We propose a Hausman-type test to balance robustness and efficiency and to check whether a robust method should be implemented. An economic application is presented. 相似文献

Several methods have been developed for filtering seasonal influences and extreme returns in financial and economic time series. The theoretical support for these approaches is rather questionable since it focuses on the effects of shocks on prices and not on their sources. Removing such effects modifies the true generating system of market dynamics because of the non-proportional character of non-linearity. Thus, taking into account that the underlying process of economic time series is highly non-linear we cannot be certain a priori what the impact of new information will be on the dynamic structure of a system. The main contribution of this paper is to demonstrate using the methodology of simulations the eventual distortions in time series data arising from the arrival of news when agents follow non-linear trading strategies. We argue that if news can really modify the dynamical behaviour of a system, then the methodology of filtering exogenous distortions needs to be re-examined. 相似文献

The digitization of content has led to the emergence of platforms that draw information from multiple sources. This paper investigates whether aggregation of content by a single platform encourages users to “skim” content or to investigate it in depth. We study a contract dispute that led a major aggregator to remove information from a major content provider. After the removal, users were less likely to investigate additional, related content in depth, particularly sources that were horizontally or vertically differentiated. 相似文献

The high public regard for nurses has not necessarily translated into an adequate supply of individuals who are willing to be nurses. The expected future demand for nurse labor challenges us to look more closely at the public's perceptions of nursing and nursing careers, and consider how they are shaped by personal experience, media messages, and socio-demographic factors. As part of ongoing efforts to examine factors shaping the future of the nursing workforce, a national survey of Americans was conducted to probe attitudes toward the nursing profession and their experiences with nurses. The data in this national survey of the public about nursing demonstrate that the nursing profession is highly respected and that the vast majority of the general public would recommend nursing careers to qualified students. If the profession is so well thought of and so highly recommended, why are there persistent concerns that not enough people are becoming RNs to avoid or at least slow down the development of future shortages? A prolonged and persistent effort is needed to educate people about nursing careers, to stimulate the expanded production of nursing faculty, and to bring creative approaches to financing nursing education and workforce improvements to convert the large number of seriously interested candidates into the nursing profession. 相似文献
