Document Summary

Depend on value judgements and cannot be evaluated solely by a recluse to facts. A statement about what ought to be as opposed to what actually is. Do not involve value judgements, they are statements about matters of fact and so disagreements of them are appropriately dealt with by an appeal to evidence. A statement about what actually is (was or will be), as opposed to what ought to be. Distinguishing what is actually true from what we would like to be true requires distinguishing between positive and normative statements. A variable is a well-de ned item, such as a price or a quantity, that can take on different possible values. Any well-de ned item, such as the price or quantity of a commodity, that can take on carious speci c values. An endogenous variable is one whose value is determined within the theory. A variable that is explained within a theory.

I have 8 questions out of 20 I am stuck on... I was hoping I couldget some second opinions, I will post the ones I got simple answersfor, detail is also apparently important as each questions would be6 marks on an test. Thanks!!

Explain why each of the following statements is True, False, orUncertain according to economic principles. Use diagrams whereappropriate. Unsupported answers will receive no marks. It is theexplanation that is important.

2.The sentence below is an example of a purely positive economicstatement.
âDuring a recession the government must increase its spending toreplace reduced private spending and reduce unemployment even ifthis leads to an increase in the national debt.â

[My Answer]
This statement is false. A positive statement is a statement aboutwhat actually is, as opposed to what ought to be. This statement isnormative advice because value judgments are being made about whatthe government could do with its limited resources and it refers towhat ought to be as opposed to what actually is.

These questions are worth 6 marks, I'm not sure that I'm clearenough or have the full point across... Thanks!
