If we introduced another variable, TIME, into the demand for butter equation so that the original equation becomes:

Q_d = 145 – 1.25P – 0.001Y + 2P_m – 4.5TIME

Where the TIME term takes a value of 1 for 2001, 2 for 2002 and so on, until it has a value of 10 for 2010.

What would happen to the estimated demand for butter? And why might this happen?

3. The following is a hypothetical estimate of a demand curve for butter over the period 2001–10.
Qa = 145 – 1.5P – 0.0017+ 2Pm
Where Qa is the quantity of butter sold in grams per person per week;
Pis the price of butter (in pence per kg, at 2000 prices);
Y is the annual disposable income per head (in £s at 2000 prices);
Pm is the price of margarine (in pence per kg, at 2000 prices).
