Economics analysis evaluation

A useful example of sustainable design comes from BASF, and their development of the eco-efficiency tool. This tool seeks to integrate the combined aspects of each of the three pillars in an attempt to quantify the most sustainable products and illustrates some of the concerns associated with evaluating sustainable products. For example, the economic analysis includes a total cost of ownership that goes beyond the purchase price of a product to incorporate the cost of operation, the cost of environmental health and safety, and the cost of labour. Thus, even though a product may have a lower purchase price, it may be more expensive to use and thus costlier over the total life cycle of the product. 

Economic evaluations are usually carried out by a specialists group within a company, although in a small fine chemicals company the economic analysis often is the task of the chemical engineer. 

Most proprietary spreadsheets have procedures for calculating the cumulative NPW from a listing of the yearly net annual revenue (profit). Spreadsheets are useful tools for economic analysis and project evaluation. 

Economic analysis/valuation of specific functions or services provided by the natural system (i.e. the ecosystem) and of the (societal) costs and benefits of the measures proposed to restore these services, contributes to the transparency of the decisions. Concerning the system, a better definition of water services is needed in order to evaluate recovery costs of water uses and environmental costs. The economic analysis should also include a valuation of water and ecosystem services. For instance, the delivery of clean water by the ecosystem (e.g. through its filtering capacity or capacity to degrade contaminants) is one of these services. 

So far we have explained how to estimate capital and operating costs. In Example 3.3, we formulated an objective function for economic evaluation and discovered that although the revenues and operating costs occur in the future, most capital costs are incurred at the beginning of a project. How can these two classes of costs be evaluated fairly The economic analysis of projects that incur income and expense over time should include the concept of the time value of money. This concept means that a unit of money (dollar, yen, euro, etc.) on hand now is worth more than the same unit of money in the future. Why Because 1000 invested today can earn additional dollars in other words, the value of 1000 received in the future will be less than the present value of 1000.

This means the obligation to carry out an extensive, quantitative risk evaluation and socio-economic analysis of the alternatives being considered by the authorities with, at the same time, a legally and systematically founded lack of information. 

An EPA report "Disposal of Dilute Pesticide Solutions" ( ) summarized technologies used In disposal of such wastes. Another study entitled "Economic Analysis of Pesticide Disposal Methods" (j4) evaluated commonly used disposal systems In terms of cost. Local, regional and statewide collection and disposal strategies were also considered. Although each of these reports contain valuable Information, they fall short of the target of providing adequate Information to pesticide regulators and users to draw upon In day-today operations. 

More generally, the presence or absence of good clinical data imposes limits on the economic evaluations that can be conducted. It is usually easier to undertake economic evaluations of drug therapies, where there are usually some reasonable clinical data, as compared with medical devices or procedures. However, even for drugs, the data from standard Phase 3 clinical trials are far from ideal. These trials are usually conducted under conditions that are atypical of normal practice. In addition, they are often of short duration and often fail to compare the most relevant alternatives for economic evaluation. This means that decision-analytic modeling is usually required as a supplement to, or alternative to, economic analysis alongside trials. 

Another dimension of economic analysis of clinical practice illustrated by Fig. 1 is the evaluation of costs of a therapy. Economists consider three types of costs - direct, productivity, and intangible. 

In summary, economic analysis of medical technology or medical care evaluates a medical service by comparing its monetary cost with its monetary benefit (cost-benefit), by measuring its monetary cost in relation to its outcomes (cost-effectiveness), or simply by tabulating the costs involved (cost-identification). Direct costs are generated as services are provided. In addition, productivity costs should be considered, especially in determining the benefit of a service that decreases morbidity or mortality. Finally, the perspective of the study determines the costs and benefits that will be quantified in the analysis, and sensitivity analyses test the effects of changes in variable specifications for estimated measures on the results of the study.

Innovative Technology Evaluation (SITE) demonstration program. Based on information from the demonstration, an economic analysis was performed to estimate costs associated with a commercial-size unit using the technology. CF Systems developed criteria and costs for a base case and a hot spot case and then extrapolated these costs to three other cases (D132627, p. 21). 

Table 2 summarizes the costs associated with remediating a hypothetical site. The economic analysis is extrapolated from a cost estimate prepared during a U.S. Environmental Protection Agency s (EPA s) Superfund Innovative Technology Evaluation (SITE) demonstration of... 

Therefore, an economic analysis must measure the quality of life of the patient to ensure that the value of the drug incorporates the patient s perspective. Quality of life is a concept that usually incorporates the physical, mental and social well-being of the patient. Initial doubts concerning the ability of schizophrenic patients to provide reliable and valid reports of their own quality of life led to the use of proxies for patient interviews. Caregivers and clinicians were consulted most often. However, recent research has shown that the use of proxies can produce very different results to those derived directly from the patient s responses. In addition, research now indicates that schizophrenic patients are able to provide stable, reliable and valid self-reports of their psychological well-being, health status and subjective evaluation of drug therapies (Awad et al., 1995).
