The hypothesis of the expectations-augmented
Phillips curve holds that:
a) employment contracts fully accommodate the rate of price inflation
b) job-seekers never make systematic errors
c) wage settlements are partially determined by the expected rate of price
inflation
d) reservation wages are determined by minimum wage legislation
2010 Exam Q32
Which of the following statement is true? With the
expectations-augmented interpretation of the
Phillips curve, Milton Friedman assumes that
a) monetary policy is the exogenous variable, that causes variations in
unemployment
b) trade union activity is the exogenous variable, that causes variations
in unemployment
c) unemployment is the exogenous variable, that causes variations in
inflation
d) monetary policy is the exogenous variable, used to counter
variations in unemployment
2013 Exam Q33
Expectations Augmented Phillips Curve
• Initially, unemployment and inflation
are at point A.
• Expansionist monetary policy would
increase consumption, shifting to
point B along the Phillips curve
• Unemployment is reduced but there is a
trade off; inflation.
• After a short period, agents will
associate expansionist policies with
inflation and will push for higher
wages. (Gerry: Price-wage spiral)
• This will stop the consumption
stimulus and also de-incentivise hiring.
Agents will shift their expectations
curves to point C.

The hypothesis of rational expectations contends that
individuals:
a)
b)
c)
d)
do not make systematic errors
anticipate future prices accurately
adapt slowly to the rate of inflation
only make rational errors

Rational Expectations:
• Rational expectations is a hypothesis in economics which states that
agents' predictions of the future value of economically relevant
variables are not systematically wrong in that all errors are random.

‘that any ____I____ will tend to collapse once
pressure is placed upon it for control purposes.’
a)
b)
c)
d)
monetary target
observed statistical regularity

2010 Exam Q35
Goodhart’s Law
• Any observed statistical regularity will tend to collapse once pressure
is placed upon it for control purposes.
• (Goodhart's original 1975 formulation, reprinted on p. 116 in
Goodhart 1981[2])
Suppose that national income (measured in 1990 prices) is
£1000 billion. Suppose further that prices have doubled
since 1990 and that the typical unit of money circulates
around the economy 20 times per year.
What is the money supply?
a)
b)
c)
d)
£50 billion
£100 billion
£150 billion
£200 billion
2010 Exam Q36
MV = QP
We know that:
V = 20
Q = 1000
P=2
So, solving for M:
MV=PQ
M = QP/V
M = 1000*2/20
M = 100
If the LM curve is vertical, then:
a)
b)
c)
d)
full crowding out occurs
fiscal policy will be infinitely effective
monetary policy will not work
supply side policies will be unavailable
2010 Exam Q38
‘Crowding out’ occurs if new public expenditure
a) is insufficient to maintain social services
b) creates excess demand and over-full employment
c) attracts an influx of economic migrants
d) diverts expenditure from existing productive activities
2013 Exam Q31
Vertical LM curve
• If the demand for money is not related to the
interest rate, as the vertical LM curve implies,
then there is unique level of income at which
the money market is in equilibrium.
• Thus, with vertical LM curve, an increase in
government spending (which shifts the IS curve)
cannot change the equilibrium income and only
raises the equilibrium interest rates.
• If government spending is higher and the
output is unchanged, there must be an
offsetting reduction in private spending.
• In this case, the increase in interest rates crowds out
an amount of private spending equal to increase in
government spending.
• Thus, there is full crowding out if LM is vertical.
As defined in Keynes’s General Theory, ‘involuntary
unemployment’ relates to individuals whose
employment prospects would be raised by:
(a) a rise in the price of wage goods (i.e., a rise in the cost of living)
(b) a fall in the price of wage goods (i.e., a fall in the cost of living)
(c) greater trade union participation
(d) a shift to capital-intensive production methods

2013 Exam Q30
Keynes on involuntary unemployment
• “Clearly we do not mean by ‘involuntary’ unemployment the mere existence of
an unexhausted capacity to work. An eight-hour day does not constitute
unemployment because it is not beyond human capacity to work ten hours. Nor
should we regard as ‘involuntary’ unemployment the withdrawal of their labour
by a body of workers because they do not choose to work for less than a certain
real reward. Furthermore, it will be convenient to exclude ‘frictional’
unemployment from our definition of ‘involuntary’ unemployment. My definition
is, therefore, as follows: Men are involuntarily unemployed if, in the event of a
small rise in the price of wage-goods [i.e., consumer goods] relatively to the
money-wage [i.e., nominal wage], both the aggregate supply of labour willing
to work for the current money-wage and the aggregate demand for it at that
wage would be greater than the existing volume of employment.”

and the car exporter uses the payment to buy UK
government bonds, which of the following statements
would be true?

(b) UK net exports rise and net capital exports rise
(c) UK net exports fall and net capital exports rise
(d) UK net exports rise and net capital exports fall
2012 Exam Q34
Net Exports
• If a UK resident citizen buys a BMW car from Germany
• This is a German export and UK import of a tangible good
• The car exporter uses the payment to buy UK government bonds
• This is a German import and UK export of a capital good
The original Phillips curve identified a robust
correlation between:
(a) unemployment and the rate of change of real wage rates
(b) unemployment and the rate of change of money wage rates
(c) wage levels and unemployment
(d) wage levels and inflation
2012 Exam Q35
Indicate which one of the following statements is
true. With the original interpretation of the
Phillips curve, A.W. Phillips assumes that
a) wage bargaining is the exogenous variable, that causes variations in
money wages
b) the business cycle (as reflected in the unemployment rate) is the
exogenous variable, that causes variations in increases in money wages
c) the real wage is the exogenous variable, that causes variations in
inflation
d) inflation is the exogenous variable, that causes variations in
unemployment
2013 Exam Q32

b) shifts up
c) becomes flatter
d) becomes steeper
2011 Exam Q32
Expectations Augmented Phillips Curve
• Initially, unemployment and inflation
are at point A.
• Expansionist monetary policy would
increase consumption, shifting to
point B along the Phillips curve
• Unemployment is reduced but there is a
trade off; inflation.
• After a short period, agents will
associate expansionist policies with
inflation and will push for higher
wages.
• This will stop the consumption
stimulus and also de-incentivise hiring.
Agents will shift their expectations
curves to point C.
If job seekers under-estimate the rate of inflation, the
duration of the job-search:
(a) shortens, so that unemployment tends to rise
(b) lengthens, so that unemployment tends to fall
(c) shortens, so that unemployment tends to fall
(d) lengthens, so that unemployment tends to rise
2012 Exam Q36
If job seekers under-estimate the rate of
inflation
• Then they will over-estimate the value of an offered wage contract
• And will accept a lower real wage
• And thus will have a shorter period of unemployment

varied systematically with respect to:
(a) the trade deficit and the value of sterling
(b) employment and the cost of living
(c) inflation and the ‘output gap’
(d) tax revenues and the level of government borrowing
2012 Exam Q38
Taylor rule
The Taylor rule equation is written as:
rt = r* + π* + w(πt – π*) + (1 – w)(yt – y*)/y*
where:
rt is the central bank discount rate
πt is the inflation rate
π* is the inflation rate target
y is the GDP
y* is the potential GDP
w is the policy parameter
Define r as the real rate of interest and let r* be the
rate consistent with long run equilibrium in the
economy. Further, define π as the rate of inflation and
π* as the target rate of inflation.
Then r = r* + α(π – π*) is:
a)
b)
c)
d)
an LM curve
a Taylor rule
a DSGE model
incomprehensible

According to the ‘Lucas critique’, economic
forecasts are
a) always unreliable
b) most reliable when economic policy is stable
c) most unreliable when a change in economic policy is implemented
d) most unreliable when inflation is accelerating
2013 Exam Q38
Theory of Economic Policy (Lecture 57 Slide 42)
Policy instruments and
objectives
New Classical Economics – the Lucas critique
Economic forecasts are most unreliable when they are most needed; i.e., when
a change in economic policy is to be implemented
Even if individuals’ expectations could be forecast in the context of current
policy structures, that ‘success’ is undermined when that policy structure
changes
New policy implies a new context in which decisions are taken: so individuals’
reactions
are affected
Behavioural adjustments to changes in policy structures emasculate
macroeconomic forecasting and (with it) aggregate demand management
Robert Lucas (1937 - )
Nobel Prize 1995 …
‘for having developed and applied the
hypothesis of rational expectations, and
thereby having transformed
macroeconomic analysis and deepened our
understanding of economic policy’
Quantitative easing is a process whereby a central bank:
a) sells long-term government bonds
b) purchases long-term government bonds
c) sells short-term government bonds
d) purchases short-term government bonds
2011 Exam Q35
Lecture 56: Question 5
What is quantitative easing?
• Expansionary monetary policy usually involves the central bank
buying short-term government bonds in order to lower short-term
market interest rates.
• However, when short-term interest rates are either at, or close to,
zero, normal monetary policy can no longer lower interest rates.
• That’s where quantitative easing comes in.
• Quantitative easing involves purchasing long-term bonds (gilts) in an
attempt to lower the long-term interest rate and increase money
supply
Which of the following is not a function of the Bank of
England?
a)

c)
d)
lender of last resort
supplier of money
acting as a store of value
determining the official interest rate
2010 Exam Q40

reserves
b) sells foreign exchange reserves to support the value of the domestic
currency
c) allows the international value of its currency to be determined by
market forces
d) is taking advantage of a trade surplus to build its foreign exchange
reserves
2013 Exam Q39

With the Keynesian (liquidity preference) theory the
interest rate is determined by:
a) the asset demand to hold money
b) the speculative demand to hold money
c) expectations relating to future bond prices
d) all of the above
2011 Exam Q37
A nation with a fixed exchange rate cannot insulate
itself from world inflation because, if initially its
domestic inflation rate is lower than elsewhere:
a) economic recession forces domestic prices up
b) domestic goods become less competitive and cost-push inflation raises
domestic prices
c) domestic goods become more competitive which tends to increase
money in domestic circulation
d) none of the above
2011 Exam Q39
Under a fixed exchange rate
• Low domestic inflation will cause the price of goods to rise more
slowly than in other countries
• So other countries will seek to buy goods from the low inflation
country
• This will increase the amount of capital in the low inflation country
• This will put upward pressure on the low inflation country’s currency
