by how much will the sales of good B change by?
b. If goods A and B are substitutes and the price of good A increases, how will
this affect the demand for good B?

3. Consider the model Q d = f ( P, P s , P c , INC ) where Q d is quantity demanded of a

equation represents _____.

4. Economic theory provides a basis for which variables are relevant and should be
included in an econometric model. But econometrics provides tools to estimate _____
which tells us _____.
a. a model; the functional form that should be used
b. causality; why it happens that way

5. Why is a random error term included in an econometric model?
a. Because many economic models have not been well developed yet and need
to allow for inaccuracies.
b. Because some people are irrational.
c. Because there is intrinsic uncertainty in any economic activity due to
individual decision making.
d. Because most estimating techniques are not well suited to work with a
deterministic model.

6. Refer to the equation Q s =β1 + β 2 P + β3 P r + β 4 P s + β5TAX + e where Q s is annual
quantity supplied, P is the price of the product, P r is the price of resources, P s is the
price of goods that are substitutes in production, and TAX is the excise tax on the
product. This equation is _____.
a. an economic model

price of goods that are substitutes in production, and TAX is the excise tax on the
product. In this equation, β1 represents _____.
