Market impact cost is a measure of market liquidity that reflects the cost faced by a trader of an index or security. [1] The market impact cost is measured in the chosen numeraire of the market, and is how much additionally a trader must pay over the initial price due to market slippage, i.e. the cost incurred because the transaction itself changed the price of the asset.

By contrast, cost-benefit analysis is a technique rooted in social science that is most often used by funders outside an organization to determine whether their investment or grant is economically efficient, although economic efficiency also encompasses social and environmental considerations.
An economic impact analysis only covers specific types of economic activity. Some social impacts that affect a region's quality of life, such as safety and pollution, may be analyzed as part of a social impact assessment, but not an economic impact analysis, even if the economic value of those factors could be quantified.

Implementation shortfall is a commonly targeted benchmark, which is the sum of all explicit and implicit costs. Sometimes, an opportunity cost of not transacting is factored in. [5] After measurement, costs must be attributed to their underlying causes. Finally, this analysis is used to evaluate performance and monitor future transactions.
An estimation of the CAPM and the security market line (purple) for the Dow Jones Industrial Average over 3 years for monthly data.. In finance, the capital asset pricing model (CAPM) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio.
A 1995 study of the cost-effectiveness of reviewed over 500 life-saving interventions found that the median cost-effectiveness was $42,000 per life-year saved. [7] A 2006 systematic review found that industry-funded studies often concluded with cost-effective ratios below $20,000 per QALY and low quality studies and those conducted outside the ...
If the assessment is favourable, and the proposed policy is enacted—after a suitable length of time for the policy to gain traction—it might be followed by an impact evaluation; ideally, assessed impacts before the fact and evaluated impacts after the fact are not wildly divergent. In some cases, impact becomes politicized due to a change ...
In the early 1970s Paul R. Ehrlich and John Holdren developed the lettering formula I = PAT to describe the impact of human activity on the environment. [4] Furthermore, the concept of eco-efficiency was first described by McIntyre and Thornton in 1978, [ 5 ] but it wasn't until 1992, when the term was formally coined and widely publicized by ...
