We develop and test an empirical model of individuals’ intertemporal demands for health risk-mitigation programs over the remaining years of their lives. We estimate this model using data from an innovative national survey of demand for preventative health care. We find qualified support for the Erhlich (2000) life-cycle model, which predicts that individuals expect to derive increasing margina...
Introduction: Widespread immunization is critical to bringing the COVID-19 pandemic an end. The objective of this cross-sectional data analysis was investigate impact vaccination on frequency occurrence and presence its symptoms clinical presentations. Material methods: This a retrospective, study, analysing medical records patients hospitalized at Dr Antoni Jurasz University Hospital No. 1 in ...
Road accident is one of the major causes of death in KSA. Therefore, making some important decisions, such as investing in traffic safety, improving roads or distributing research priorities and the necessary activities to strengthen the safety, all require either implicitly or explicitly the evaluation and estimation of the costs of these incidents, in order to make sure that those investments...
This paper reports estimates of the value of statistical lives using the labor market behavior of wave 2 of the Health and Retirement Survey (HRS). By exploiting the panel structure of the HRS, it is possible to provide the first test of the Pratt-Zeckhauser "dead anyway" hypothesis and to measure the importance of health status and quality of life for value of statistical life (VSL) estimates....
This study uses both risk-risk and risk-dollar approaches to assess intangible health losses associated with multiple sclerosis (MS). Using an estimation approach that adjusts for potential perceptional biases that may effect the expressed risk tradeoffs, we estimated parameters of the utility function of persons with and without MS as well as the degree of subjects" overestimation of the proba...
Happiness surveys based on self-report can generate unreliable data due to respondents’ imperfect retrospection, vulnerability to context, and arbitrariness in measuring happiness. To overcome these problems, this article proposes to incorporate a method of measuring happiness, which is developed by Ng (1996) based on Edgeworth’s notion of “Just Perceivable Increment” of happiness, with the Day...
In this paper I estimate an age-adjusted value of statistical life (VSL) by examining consumer automobile purchases. Many public policies target the health and safety of older people, but most VSL estimates come from hedonic wage regressions with few older workers and no retirees. Although underrepresented in the labor force, senior citizens account for a sizeable share of vehicle acquisitions ...
عناب (Ziziphus jujuba Mill.) از درختان دارویی ارزشمندی است که در ایران پراکنش دارد. میوه این گیاه بهدلیل داشتن مواد مؤثره در صنایع غذایی و دارویی استفاده میشود. در این مطالعه برخی صفات فیتوشیمیایی، مورفولوژیکی و عناصر معدنی میوه 23 اکوتیپ عناب واقع در ایستگاه تحقیقات بدیعی در بخش گازرون استان قم (J1-J23) اندازهگیری شد. کربوهیدرات محلول کل (TSC) نمونهها از 54/5% تا 36/23% متغیر بود. بیشترین ...
We report on the results of a survey based on conjoint choice experiments that was specifically designed to investigate the effect of context on the Value of a Statistical Life (VSL), an important input into the calculation of the mortality benefits of environmental policies that reduce premature mortality. We define ―context‖ broadly to include i) the cause of death (respiratory illness, cance...
We use conjoint choice questions to investigate people’s preferences for income and reductions in mortality risks delivered by contaminated site remediation policies. Our survey is self-administered using the computer by residents of four cities in Italy with severely contaminated sites. We estimate the Value of a Statistical Life to be about €5-6 million for an immediate risk reduction. If the...
