why is the production possibilities curve imperfect?

musical trade-off[edit]

what about bands like stratovarius and children of bodom...would the volley of guitar and keyboard solos be considered trade offs too?--66.146.147.120 16:47, 14 October 2007 (UTC)

I've just deleted this section as irrelevant to the subject matter of the article - it might be suitable for a dictionary entry but not here:

In music, the term "tradeoff" can also refer to solo instruments that swap solo duties, such as musical groups with two lead guitarists, who both share guitar solos. The term is used frequently in heavy metal, where bands often feature "twin guitars", such as Iron Maiden, Judas Priest, Megadeth, and Slayer, all of which feature lead guitar song sections that may involve four or more "tradeoff" solos. A more limited number of bands, such as Dream Theater, also implement the tradeoff with keyboards and lead guitar.

De Loof "cite"[edit]

There has been an attempt to get the De Loof paper (Longevity and aging in insects: Is reproduction costly; cheap; beneficial or irrelevant? A critical evaluation of the ‘‘trade-off’’ concept, 2011) used as a cite for the meaning of a trade off. This is, I suspect, entirely mischievous since the De Loof paper takes its definition of trade off from this very Wikipedia article. JackAidley (talk) 13:00, 3 January 2011 (UTC)

Pareto[edit]

This topic is related and partially overlapping with Pareto optimality. Jahobr (talk) 09:40, 13 April 2011 (UTC)

Dr. Peeters's comment on this article[edit]

Dr. Peeters has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:


...In economics, a trade-off is sometimes associated with (instead of: expressed as) an opportunity cost ...

Please replace "The old saying ... few stocks" by:

In financial economics, a tradeoff exists between risk and return. By buying stocks instead of bonds, for instance, the return is higher since stocks have a higher risk. Investing in bonds tends to be less risky, but it renders a lower return.

Please delete the whole section titled "tradeoffs in economics". Opportunity costs are not only associated with tradeoffs.

In the example of demography, we need a reference to a scientific article.


We hope Wikipedians on this talk page can take advantage of these comments and improve the quality of the article accordingly.

Dr. Vanzetti's comment on this article[edit]

Dr. Vanzetti has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:


Trade-offs are central to economics, which is concerned with the allocation of scarce resources to satisfy unlimited wants. This article is not that helpful in drawing that out.

A better definition of opportunity costs might be: "An opportunity cost is the cost of an alternative that must be forgone in order to pursue a certain action. Put another way, the benefits you could have received by taking an alternative action." In the example, for a person going to a basketball game, their opportunity cost is watching a particular television program at home, not the money and time expended.

trade study section relocated here for reworking[edit]

As it currently stands, the section on trade studies provided interesting information about decisionmaking and algorithms, but it didn't specifically discuss trade-offs. Not sure this article is best place for this section.OnBeyondZebraxTALK 10:33, 10 June 2017 (UTC)

  • Trade study section:

Trade studies are decision-making exercises. In the FAA Systems Handbook.[1] the decision analysis matrix (also called Pugh's method) is suggested to support the activities, but this method cannot support uncertainty, a mix of quantitative and qualitative information, or teams. To manage uncertainty, the authors suggest supplementing point estimates of the outcome variables for each alternative with computed or estimated uncertainty ranges. The Standard Approach to Trade Studies,[2] an INCOSE paper from 2004, suggests a similar approach.

In the NASA Systems Engineering Handbook[3] NASA suggests using multi-attribute utility theoretic (MAUT) or the Analytic Hierarchy Process (AHP). But, these too are not good with uncertainty, mixed information and teams. The authors suggest using probability based methods to maximize utility when uncertainty predominates, but give little detail on how to approach this.

In many situations, linear programming methods like the simplex algorithm can be used but these too do not support uncertainty. Another approach to supporting trade studies with uncertain information is to use the Bayesian methods.[4]
