PREVIEW OF QUESTION 1
1. 3 Reference: Prescribed book PG 277
Although production, income and spending all occur simultaneously, it is useful to consider these
three flows in sequence, starting with production. Production creates income which is then used to
purchase the products that were produced in the first place. By definition, income is always equal to
production but there is no guarantee that all income will be spent. Spending may be equal to, greater
than or less than income.

Why do firms purchase capital goods? In other words, why do they invest? The answer is simple –
firms invest because they hope to earn profits. They estimate the cost of the capital goods concerned
(eg buildings, machinery, equipment) and compare these costs to the amounts they expect to earn
from the investment. The greater the expected profit, the greater investment will tend to be. If no
profit is expected, there will be no investment.

The multiplier effect is the magnified increase in equilibrium GDP that occurs when any component of
aggregate expenditures changes. The greater the MPC (the smaller the MPS), the greater the
