remain unchanged.
none of the above

If a consumer with a given income is maximising her utility, then we can certainly conclude that:
the marginal utility from an additional unit of each good is zero.
the marginal utility from an additional unit of each good is the same.
the marginal utility from the last dollar spent is the same for each good.
the amount spent on each good is the same
Anne consumes only mobile phones and cereal. Suppose that the price of mobile phones goes up (ceteris paribus). Anne is observed to reduce her mobile phone consumption and her marginal utility from mobile phones declines. We can conclude from this information that:
Anne's marginal utility from cereal has declined.
Anne's total utility has increased
Anne's cereal consumption has increased
Anne is irrational
The demand curve faced by a monopolist is
infinitely elastic
infinitely inelastic
its marginal revenue curve.
the market demand curve.
If marginal cost decreases, a monopolist will
reduce price and decrease quantity of output
reduce price and increase quantity of output.
increase price and reduce quantity of output
increase price and increase quantity of output
A shift to the right of a producer's supply of motor vehicles could indicate:
an expectation of price rises for other goods that could be manufactured.
a decline in the price of cars
a decline in technological expertise.
a decline in the price of required inputs.
The principle of diminishing marginal returns to the variable inputs means that:
the average cost curve must initially be decreasing.
the supply curve is linear
the supply curve is non-linear.
the average cost curve is eventually increasing.
If at the current level of output for a firm, average cost (AC) is E6 and marginal cost (MC) is E5 then:
the MC curve will not intersect the AC curve at the AC curve’s minimum point.
there are decreasing returns to scale
since MC is less than AC, AC must be decreasing.
since MC is less than AC, AC must be increasing.
Perfectly competitive long run equilibrium exists where price:
equals marginal cost
equals average variable cost
equals minimum average cost
all of the above
In long run equilibrium in a monopolistically competitive industry:
price equals marginal cost and profits are zero
price equals average cost and profits are positive.
price is greater than marginal cost and profits are zero.
price is greater than marginal cost and profits are positive.
Social costs will equal private costs if
the market mechanism leads to an efficient allocation of resources
the firm faces an upward sloping marginal cost curve.
all of the above
some of the costs of production are borne by third parties.
Assume the production of a good imposes negative externalities. If the government forces producers to pay the external costs, then:
the equilibrium quantity of the good will increase.
the price of the good will decline
the equilibrium quantity of the good will stay the same.
the equilibrium quantity of the good will decline.
An individual worker’s supply of labour curve is usually assumed to:
be negatively sloped at all wage rates
become negatively sloped at very high wage rates
become positively sloped only at very high wage rates.
be negatively sloped at very low wage rates
A firm that hires workers in a perfectly competitive labour market will:
have an upward sloping marginal factor cost curve if the firm sells in a perfectly competitive market.
hire fewer workers when it sells in competitive markets than when it sells in a monopolistic market.
hire more workers when it sells in competitive markets than when it sells in a monopolistic market.
prefer labour to capital
Which of the following will bring about an outward shift in the production possibilities curve?
An increase in the number of unemployed workers.
An increase in the quality of labour resources

Suppose that the consumer price index rises from 1000 to 2000. We may conclude:
the real income of a person on a fixed nominal income has been cut in half.
all prices in the economy have doubled
consumer incomes have doubled
all of the above
Which of the following statements is correct?
Potential real GDP (Gross Domestic Product) is always greater than equilibrium real GDP.
The purchase of shares in the stock market is an example of investment spending.
Real GDP is the total value, measured in base year prices, of all final goods and services produced in a country in one year.
None of the above
The simultaneous occurrence of high unemployment, high inflation and sluggish growth in real national income is known as:
stagflation
contraction
expansion
recession
A type of unemployment in which workers are in- between jobs or are searching for better jobs is called:
cyclical
frictional.
structural

Crowding out refers to the reduction in planned investment that occurs when:
nominal interest rates decline
an increase in the transactions demand for money reduces real interest rates.
an increase in planned expenditure leads to a rise in the real interest rate.
wage rates fall making labour cheaper
If nominal GDP fell while real GDP rose, which of the following must be true?

Net exports were negative
Nominal interest rates rose by less than the rate of inflation.

The natural rate of unemployment is the rate that
occurs when there is only structural unemployment in the economy
prevails in long run equilibrium.
appears when money illusion influences people's choices.
is a short run phenomenon
If the actual unemployment rate is below the natural rate of unemployment then we might expect:
the rate of inflation to increase.
the Phillips curve to shift to the left
a fall in the wage rate
the natural rate of unemployment to fall
Assume equilibrium GDP is E400 billion andpotential GDP is E500 billion. According to the simple Keynesian model, if the marginal propensity to consume is 0.8, by how much should government spending be changed in order for equilibrium GDP to equal potential GDP?

Increase by E20 billion
Increase by E80 billion
Decrease by E80 billion
