The time trade-off (TTO) valuation technique is widely used to determine utility values of health outcomes to inform quality-adjusted life-year (QALY) calculations for use in economic evaluation. Protocols for implementing TTO vary in aspects such as the trade-off framework, iteration procedure and its administration model and method, training of respondents and interviewers, and quality contro...

before making decisions about the investment and financing the companies. it is necessary to know how the value of a company is determined. in this article three valuation methods are discussed: 1) value dirver method. 2) free cash flow method 3) economic value added method. in these methods the factors affecting the value of companies such as operating rate of return, cost of capital. amount o...

This paper provides the latest research developments in the method of choice experiments applied to valuation of non-market goods. Choice experiments, along with the, by now, well-known contingent valuation method, are very important tools for valuing non-market goods and the results are used in both cost-benefit analyses and litigations related to damage assessments. The paper should provide t...

Sea-level rise, as a result of climate change, will likely inflict considerable economic consequences on coastal regions, particularly low-lying island states like Singapore. Although the literature has addressed the vulnerability of developed coastal lands, this is the first economic study to address nonmarket lands, such as beaches, marshes and mangrove estuaries. This travel cost and conting...

Methods to assess ecosystem services using ecological or economic approaches are considerably better defined than methods for the social approach. To identify why the social approach remains unclear, we reviewed current trends in the literature. We found two main reasons: (i) the cultural ecosystem services are usually used to represent the whole social approach, and (ii) the economic valuation...

BACKGROUND Quality of life as an endpoint in a clinical study may be sensitive to the value set used to derive a single score. Focusing on patients' actual valuations in a clinical study, we compare different value sets for the EQ-5D-3L and assess how well they reproduce patients' reported results. METHODS A clinical study comparing inpatient (n = 98) and outpatient (n = 47) rehabilitation of...

Are we cutting down tropical forests too rapidly and too extensively? If so, why? Answers to both questions are obscured in some ways by insufficient and unreliable data on the economic worth of forest ecosystem services. It is clear, however, that rapid, excessive cutting of forests can irreversibly and substantively impair ecosystem functions, thereby endangering the flow of several socially ...

I explore the equilibrium value implications of economic models that incorporate responses to a stochastic environment with growth. I propose dynamic valuation decompositions (DVD’s) designed to distinguish components of an underlying economic model that influence values over long investment horizons from components that impact only the short run. A DVD represents the values of stochastically g...

This study describes and evaluates the various schemes available for weighting the different impacts of alternative waste management options, including landfill, composting, re-use, recycling and source reduction. The context of the study is life cycle assessment (LCA), which seeks to describe and quantify the impacts on the environment, both in terms of resource use and emissions or wastes, of...

This paper estimates the monetary value of providing informal care by means of a well-being valuation method. This is done by assessing the compensating variation necessary to maintain the same level of well-being after an informal caregiver provides an extra hour of informal care. The informal caregiver's well-being is proxied by the answer to two subjective well-being questions that were pose...
