We compare different contingent valuation question formats with each other and with observed behaviour for a non-monetary estimation task, the expected number of kilometers travelled by automobile. Open-ended questions, open-ended follow-up questions, dichotomous choice (DC) questions, and double-bound DC questions are included. The single and double-bound DC questions result in an estimated mean about twice as high as the actual value and the open-ended mean. The DC question overestimation seems to be due to an anchoring effect leading to yea-saying behaviour. Our results about the difference between DC questions and open-ended questions is consistent with the pattern observed in contingent valuations studies of the willingness to pay. Our results indicates that DC questions seem to be associated with a general overestimation problem that is present even for simple non-monetary estimation tasks. 相似文献

With health care surfacing in political campaigns across the country and referencing virtually every one of the policy topics discussed here, nurses have an important opportunity to share their views regarding both policy substance as well as engage in the political arena. For those nurses not yet ready to run for elective office, participating in grassroots efforts of campaigns, on advisory panels, and making financial contributions to preferred candidates are important opportunities not to be missed. Given the interest in and challenges ahead associated with health care broadly and nursing specifically, there is a great deal at stake. 相似文献

The aim of evidence-based guidelines is primarily to improve patient outcomes without adding to the existing cost of care because both payers and policymakers want to identify health care costs that do not result in benefit to the patient. The purpose of the reported project was to generate a practice guideline for the treatment of uncomplicated acute cystitis in a female population, to determine the extent to which the guideline would be used by providers and to measure the cost and quality of outcomes from its use. A retrospective chart review was used to gather pre-guideline practice and cost data. Measurements included the type, frequency, and duration of antibiotic therapy and the use of urine cultures and both complications and routine followup visits. The implementation of an outpatient practice guideline resulted in a significant change in antibiotic prescribing and a trend toward a change in ordering cultures and clinic followup. There was also a significant decrease in treatment costs. 相似文献

This paper constructs a general equilibrium model of equilibrium unemployment by combining an endogenous growth model with
a variant of equilibrium search theory. The analysis offers two explanations for the causes of widening wage gap between skilled
and less-skilled labor, and rising unemployment rate among the less skilled: technological change in the form of an increase
in the size of innovations or skilled labor saving technological change in R&D activity.
In addition, the model identifies two distinct effects of faster technological progress on the aggregate unemployment rate.
First, it increases the rate of labor turnover and therefore increases the aggregate unemployment rate – the creative destruction
effect. Second, it creates R&D jobs, which offer workers complete job security, and consequently reduces the aggregate unemployment
rate – the resource reallocation effect. 相似文献

In the extant literature of business cycle predictions, the signals for business cycle turning points are generally issued with a lag of at least 5 months. In this paper, we make use of a novel and timely indicator—the Google search volume data—to help to improve the timeliness of business cycle turning point identification. We identify multiple query terms to capture the real‐time public concern on the aggregate economy, the credit market, and the labor market condition. We incorporate the query indices in a Markov‐switching framework and successfully “nowcast” the peak date within a month that the turning occurred. (JEL E37, G17) 相似文献

In the past decade (2000–2010), pirates from Somalia have carried out thousands of attacks on cargo ships sailing through the Gulf of Aden and the Indian Ocean, causing what others have identified as significant damage to maritime trade. In this paper, we use variations in the spread and intensity of Somali piracy to estimate its effect on the volume of international trade. By comparing trade volume changes along shipping routes located in pirate waters to those that are not, we estimate that Somali piracy reduced bulk commodities trade passing through the Gulf of Aden by 4.1% per year from 2000 to 2010. We find smaller reductions in total trade, consistent with the fact that not all goods are shipped by sea or are targets of pirate attacks. While our estimates suggest that the trade costs of piracy are much lower than what has been suggested in the existing literature, we find that they remain significant and unevenly distributed, with five countries and the EU shouldering 70% of the total costs. 相似文献
