Can you complete questions 1-4 please. The notes are on the page for better understanding.

Many salaried employees are given Cost of Living Adjustments, which automatically raise their
salaries in order to keep up with inflation. That type of pay increase won't affect demand. But when
consumer income rises faster than inflation, we can observe a change in demand.
A change in the price of a substitute or complementary good. If a price change convinces
consumers to buy a substitute, demand decreases. If a price change gets consumers buying more of
a complementary good, demand increases.
2.
3. A change in consumer tastes. What consumers like and don't like influences what they buy. If one
good or service becomes more “in style," demand for it will increase.
4. A change in the number of demanders. If the number of demanders changes, the number of
people who can (and will) consumer a given item will also change.
5. A change in expectations. If consumers expect any of the above changes to occur, they will adjust
their purchasing patterns accordingly. If consumers expect higher income in the future, for example,
they'll spend more now in anticipation of having more money. If they expect lower prices in the
future, they'll demand less now, postponing their purchases (and actually decreasing prices through
their diminished demand, in an economic example of a self-fulfilling prophecy.)
These factors explain the shape of the demand curve for a normal good. We can summarize the income
effect as follows: As a good becomes less expensive, more people are willing to buy it because more people
can afford to buy it. And we can explain the substitution effect like this: As a good becomes more expensive,
more people will buy a substitute good instead.

One of these things is not like the other... In this exercise, you'll see groups of phrases or concepts that
are somehow related. In each group, one item has been included that does not belong. In each problem, cross
out the one that does not belong and then write a brief explanation of your reasoning.
