Question

Marginal analysis and decision-making:

Concept: The Fundamental Assumption of Economics

All social phenomena emerge from the actions and interactions of individuals who are choosing in response to expected marginal benefits and expected marginal costs to themselves.

• Definition: Marginal is additional or incremental (amount of increase) or decremental (amount of decrease).
• Should I do (choose) activity x?
• MC(x) = the additional costs of doing x
• MB(x) = the additional benefits of doing x

Rule:

• If Expected MB(x) > Expected MC(x), do x; otherwise don't.

Application:

Would an employer ever hire anyone if the expected additional cost of his or her employment were greater than the expected marginal/additional benefit? Of course not, to do so would be irrational.

Assumptions:

In economics, we assume rationality. No one would intentionally harm themselves.

marginal analysis and decision - making:

Concept: the fundamental assumption of economics.

Ability to measure costs not only include marginal cost but also fixed cost involved in businesses. Which form the total cost function which is faced by businesses. As far as businesses ability to measure costs is concerned, Of course they have ability to measure costs or marginal costs.

As explained above, each and every businesses know the cost function of their production operations. By using that function businesses can easily calculate their marginal cost of each and every unit produced. The total cost function is look like this: Suppose, Total Cost (TC) = 10 + 2Q. In this case marginal cost (MC) is 2.

Therefore, its become very easy to measure costs or Marginal costs. Hence we can say that, Of course businesses have the ability to measure costs or Marginal costs. If you do not get anything in this solution,
