We're not talking about assessing damages. We're talking about placing a value on something.
Both sides can hire economists to accomplish that task. What that has to do with business school, I have no idea.
The no idea part is correct.
You have absolutely (sic) no idea what you are talking about.
From your various posts
1. 'Diminishing returns' and suggestions of 'dozens of models'
The concept you are struggling with is called Time Value of Money, the salient calculation being Net Present Value.
Diminishing returns is completely unrelated to TVM or NPV. Please Google it to avoid wasting further bandwidth.
2. 'Negative value in the future'
First, there are simple means to calculate this. However, you are making a couple of erroneous suggestions and/or inferences. In practical terms, we have been in a period of low inflation and interest rates. The (Positive or Negative) value of something ten years ago will not be significantly greater in absolute value terms than a more recent value. Thus, any initial positive benefit will not significantly outweigh more recent or future negative benefit just because there has been some time between them.
3. Business School and Economists
Courts would assess these values as Chewie has noted. To get an accounting of the values, they might rely on accountants. Time Value of Money is taught at business school, and utilized in business decision making processes all the time. To be fair to you, the application of TVM has been lumped under Managerial Economics - something taught at business school, of course.
Here is a good reference text for you:
Crosson, S.V., and Needles, B.E.(2008). Managerial Accounting (8th Ed). Boston: Houghton Mifflin Company
From its title, you might gain that this study could be part of the curriculum at a business school or an accounting program.
