(50) 1. (a) Aggregate Demand is defined as:
AD = C + I + G + NX
Where AD is aggregate demand, C is consumption expenditures, G is government (federal and state and
local) expenditures, and NX is net exports (Exports ? Imports).
To encourage the growth of AD, fiscal policy can influence G through changes is expenditures, such as
the fiscal stimulus of 2008 and 2009, and on C by changes in transfer payments such as Medicaid,
Medicare, unemployment benefits and Social Security that change disposable income. If such changes
take place, how are they transmitted to increase both GDP and employment? When are they least
effective and most effective in changing GDP and Employment? Has the large fiscal stimulus in 2009 had
the benefits that Congress and the Administration had anticipated?
(b) Suppose the Fed has already decided that it wants to target the money stock.
(1) Will the Fed come closer to its target by setting the interest rate at a given level, or will it do better by
fixing the money supply through open market operations? In your analysis, think in terms of the Fed�s
horizon from one Open Market Committee meeting to another � about 4-6 weeks. This analysis involves
the relative stability of money demand and the money multiplier. Consider two alternative cases: (1) a
stable demand for money allows the Fed to set an interest rate that ensures it will come close to the
target money supply; and (2) an unstable demand for money.
(2) In your analysis, discuss the proposition that the Fed may need to target interest rates in the short run
in order to meet its target money stock while in the long run it may need to pay attention to interest rates
and bank reserves and currency growth. NOTE: Shifts in money demand may reveal themselves first in
movements in interest rates � and if the Fed wants to stabilize the economy, it should respond to shifts
in money demand.
(c) Within the same general context, discuss why the Fed, if it wants to stabilize and grow GDP and
employment, has chosen a quantitative easing (QE) approach by growing bank reserves though
purchases of Treasury securities and mortgage-backed securities and the monetary base rather than an
interest rate policy (presently QE2 policy is to purchase $85 billion per month of Treasury and mortgage-
backed securities? Why has the European Central Bank (EU) and Japan followed the same policy? How
Global Decision Making 2
does this process work to stimulate economic growth? Has the QE policy since 2011 worked to increase
GDP growth and employment?
(d) In the case of a liquidity trap, what is it that makes monetary policy ineffective in such a case? Recall
that effective monetary policy requires that banks lend to willing borrowers. What does it mean for an
effective monetary policy if the velocity of money declines substantially?
Velocity (V) = Price Level (P)*Real Output (Y) / Money Supply(M)
V = P*Y/M2
Or to look at it another way: PY = VM2
So a change in M2 will lead to smaller changes in P*Y the smaller is V.
(50) 2. There are many views of the state of the global economy in the late Summer early Fall of 1998.
Below are some of these views. From your reading of Commanding Heights (Yergin and Stanislaw),
current news accounts, research into various economies and Macroeconomics (Dornbusch and Fischer),
critically analyze these statements as to the type of policies that national economies and the IMF should
pursue over the course of the next few years. Has the free market system of capitalism failed and the
“battle between government and the marketplace that is remaking the modern world” (Yergin and
Stanislaw) tilting toward government? Or, is there a middle ground that needs to be reached with a global
regulatory structure created that makes countries and their financial systems more transparent and less
tied to “crony capitalism”? Express your views, but back them up with fact and supporting argument.
The Economist (September 5, 1998) “The World Economy on the Edge: The risks of a deep global
recession are increasing. But it can be avoided so long as policymakers heed some lessons from history.”
The Economist (September 5, 1998) “The Economist all-items commodity-price index has fallen by 30
percent since mid-1997, to its lowest level in real terms for over 25 years. The prices of industrial
commodities are now at their lowest in real terms since the 1930s. This has severely hurt commodity
producers, not just in Latin America and Africa, but also in Australia and Canada.” (add in the U.S.
farmers).
The Economist (September 5, 1998) “Capitalism in retreat? A related and more worrying backlash against
the free markets is the increasing interest on the part of politicians and economists in market intervention
or capital controls as a solution to the crisis�..On September 1st, Malaysia imposed strict controls on
capital movements. And respected American economists are also now arguing the virtues of capital
controls. This, he (Paul Krugman) suggests, would break the link between domestic interest rates and
exchange rates to get their economies growing again�.Indeed, the biggest risk now to the world
economy may lie not so much in a deep recession, which could be averted. It is that there may be a
wholesale retreat for free markets.”
Robert Kuttner (Washington Post, September 7, 1998, p. A25) “Free Markets and a Free Fall World
Economy. Economic reconstruction after World War II accepted the necessity of a mixed economy. In that
era, the United States and the International Monetary Fund recognized that emergent economies could
no be the prisoners of private speculative capital. The postwar system regulated private money flows and
stabilized currencies to allow nations to develop. Today�s IMF, perversely demands exposure to
speculators as a precondition of assistance�.What we need is a program of stabilization and
reconstruction in the spirit of the post-World War II years, with limits on speculative money flows and
more development aid.”

Jeffrey Sachs (The Economist, September 12, 1998, p. 23) “Global Capitalism, Making It Work. “Global
capitalism genuinely is the best chance for the developing world to gain a foothold on the economic-
growth ladder; but with current institutions, global capitalism will not succeed widely enough or credibly
enough to create a stable world system�. The IMF bought into the investment bankers� mantra:
exchange-rate stability above all else�. The more these economies tried to defend their currencies, the
more they incited panic.”
George Soros (The Wall Street Journal, September 15, 1998, Op. Ed) “The Crisis of Global Capitalism.
�there remains the urgent need for Congress to authorize an increase in the capital for the
IMF�.Bailouts did encourage foolish behavior by banks and other lenders, which could count on the IMF
when a country got into difficulties (a moral hazard problem). But, the moral hazard now operates in the
opposite direction, in not enabling the IMF to do its work when it is most needed.”
Henry Kissinger (Washington Post, October 5, 1998, p. A21) “Perils of Globalism, The IMF is no longer
suited for dealing with economic crises. The IMF must be transformed. It should be returned to its original
purpose as a provider of expert advice and judgement, supplemented by short-term liquidity support�.

made more transparent.
John Maynard Keynes, 1931 “We are today in the middle of the greatest economic catastrophe of the
modern world�the view is held in Moscow that this is the last, the culminating crisis of capitalism and that
the existing order of society will not survive it.” As quoted in The Economist (September 5, 1998), page

(15) 3.) The growth accounting equation is (Y is aggregate GDP in real terms):
Growth rates of K (capital) and N (labor) are weighted by their respective income shares, so that each
input contributes an amount equal to the product of the input?s growth rate and their share of income to
output growth. The ? indicates the change in the variable.
Growth Accounting Equation In Per Capita Terms:
(a) Define the notion of steady state equilibrium for the economy that is the combination of per capita
GDP (y) and per capita capital (k) where the economy will remain at rest, or where per capita economic
variables are no longer changing OR
In steady state, at what rate will GDP (Y) grow?
(b) Explain why, in the Neoclassical growth model, an increase in the savings rate does not increase the
growth rate of per capita output in the long run.
(c) Explain why:
(1) An increase in the rate of growth of the population, n, reduces the steady state level of k and y
(2) An increase in n increases the steady state rate of growth of aggregate output
Global Decision Making 4
and
(1) A decrease in n increases the steady state level of k and y
(2) A decrease in n decreases the steady state rate of growth of aggregate output.
a. Fiscal policy
Fiscal policy is a combination of the policies of the government spending that influence a
country’s macroeconomic conditions. Therefore, through fiscal policy, unemployment rates are
improved, control inflation is controlled, business cycles are stabilized and interest rates are
influenced by regulators in an attempt to control the economy (Dornbusch & Fischer, 1994).
Therefore, changes in government expenditures and consumption expenditures are likely to
significantly influence the rate at which the GDP grows. For instance, increased government
expenditures both state and federal means that the funds are either invested or directed into
improvement of the infrastructure especially construction of more highways for improved
movement of goods or increasing electricity supply which ensures that both companies and
individuals can produce goods with ease (Krugman & Wells, 2006). As a result more companies
tend to be created meaning that the GDP is eventually increased. This implies that additional
government (state and federal) expenditures lead to increased GDP, creation of job opportunities
as well as lowering of the unemployment rates. This a clear indication that government
expenditures are directly proportional to the GDP, whereby an increase in government
expenditures results to an increase in the GDP while a decrease in government expenditures
results to a decrease in the GDP. A combination of increased government expenditures with
increased GDP subsequently boosts production and demand as well as reducing the rate of
unemployment.
Global Decision Making 5
Alternatively, a decrease in the consumption expenditures also translates to increased GDP and
employment mainly because it reduces the proportion of funds the government consumes and
which cannot be invested or directly used to improve the investment environment for both local
and foreign investors. Moreover, the changes in government expenditures are most effective
when a balance is achieved between the government expenditures and consumption
expenditures. For example, when the government expenditures are increased and directed
towards improving investment environment or invested while at the same time ensuring that
consumption expenditures are maintained low (Krugman, 1990). On the other hand these
changes are least effective in changing GDP and employment sometimes because the
government usually obtains all its funds from the taxes i.e. from the productive activities’ of the
private sector. Moreover, these changes are also perceived to disproportionately affect particular
groups where, for instance, increased government expenditures greatly influence the group
where the spending is directed, which in the case of government spending on building highways
construction workers are significantly influenced (Krugman & Wells, 2006).
Even if not all the benefits anticipated by Congress and the Administration were accrued from
the large fiscal stimulus in 2009, there are significant benefits that were achieved. According to
Bartlett (2010) the entire stimulus package resulted to 2.8% real GDP growth in the third quarter
as well as employment of between 600,000 and 1.6 million people as a result of the stimulus
package. The stimulus package was also found to have benefits in terms of transfer payments and
tax cuts, for example, tax cuts for individuals in the low-income group raised the GDP by $1.70
for every $1 or revenue loss; whereas the tax cuts for the corporations and the rich raised the
GDP by about 50 cents for every $1 or revenue loss (Bartlett, 2010).
Global Decision Making 6
b. Money stock
(i) The Fed would come closer to its target by fixing the money supply through open
market operations because the targeted supply of money is not directly related to the
interest rate. Therefore, this means that an increase in the quantity of produced goods
and/or the price level increases, there will be an outright increase in the demand for
money. However, if there is a decline in the economic activity and/or prices go down,
then there will be an outright decrease in the demand for money. The money supply
through open market operations means the demand for money is unstable which
implies that the interest rate cannot be set at a certain level (Krugman & Wells, 2006).
(ii) The Fed may need to target interest rates in the short run in order to meet its target
money stock while in the long run it may need to pay attention to interest rates and
bank reserves and currency growth. This is mainly because the interaction between
the quantity of supplied and demanded money is the one which determines the
interest rates. This is mainly because when the interest rate is too high, then people
will purchase bonds meaning the money will definitely be reduced. However, a
greater demand for the bonds reduces the interest rates which push them towards the
equilibrium (Krugman & Wells, 1989).
c. Quantitative Easing (QE)
In order for Fed to stabilize and grow GDP and employment, quantitative easing (QE) approach
by growing bank reserves though purchases of Treasury securities and mortgage-backed
securities and the monetary base should be the most preferred approach rather than an interest
rate policy (Krugman & Wells, 2006). This is mainly because the banks target the supply of
Global Decision Making 7
money by either selling of purchasing government bonds which results to promotion of the
economic growth eventually lowering short-term interest rates while at the same time increasing
money supply. As a result of this, the European Central Bank (EU) and Japan have followed this
policy since its acts as an easy way through which money supply can be increased and also short-
term interest rates can be lowered (Duncan, 2009). However, quantitative easing (QE) policy
usually promote economic growth mainly because it targets private sector assets and commercial
banks which encourages the banks to lend money which is then invested to meet the demand
created by the increased purchasing power. QE policy has significantly worked since 2011 to
increase GDP growth and employment because more money has been available at low short-term
interest rate which is then invested leading to increased GDP growth and employment (Krugman
& Wells, 1989).
d. Liquidity trap
In the case of liquidity trap, a monetary policy becomes ineffective on either the level of income,
or the interest rate hence making it powerless to affect the interest rate. This situation occurs
because the general public is willing to hold on to the amount of money supplied, at any
particular rate of interest mainly due the fear of foreseen adverse events such as war or deflation.
Moreover, monetary policy may also be ineffective when the interest rate is zero meaning that
the general public will not be willing to hold any bond but the money in which zero percent
interest rate is also accrued, but with an advantage of being usable in transactions (Krugman &
Wells, 2006).
When the velocity of money declines substantially it means that there is very little money in
circulation that is used to buy goods and services meaning the economy becomes less robust. So
Global Decision Making 8
an effective monetary policy will definitely increase the interest rate in order to encourage people
to release the money they are holding which eventually results to an increase in velocity of
money thereby making the economy vibrant again (Krugman & Wells, 2006).
Question two
There are different types of policies that national economies and the IMF should pursue over the
course of the next few years in order to effectively tackle the problem of global economy. For
instance, in order to stabilize the international financial system crisis prevention as well as crisis
mitigation policies need to be implemented by national economies and the IMF (Krugman &
Helpman, 1985). However, the IMF needs to implement other policies which are aimed at
addressing the problem of global economy entirely including implementing stringent policies on
surveillance, information provision, and technical assistance in order to collaboratively
contribute to the prevention of crises. Moreover, the IMF should also implement policies that
encourage lending in support of an adjustment program of a country in order to eventually
contribute to the mitigation of crises (Sachs, 1998; The Economist, 1998).
Considering the free market system of capitalism and how it operates nowadays, it is evident that
it can not be sustained for long (Dornbusch & Fischer, 1994). For instance, free market system in
capitalism is perceived to be an exploitative system where the workers are paid peanuts at the
expense of companies to make large profit margins (Sachs, 1998; Yergin & Stanislaw, 1998).
Moreover, nowadays we cannot attribute the existence of the “free market” mainly because
gigantic corporations that are in possession of immense power dominate the market through
unfair competition. In addition it is also evident that this system disregards many ethical issues in
pursuit of demand and supply hence it only works in the short-term while hurting the economies
Global Decision Making 9
in the long-run (Dornbusch & Fischer, 1994; Soros, 1998). Therefore, the current free market
system in capitalism is ineffective mainly because of its vicious cycles of deflation and inflation
that in most cases tend to be very difficult to control. Furthermore, the free market system in
capitalism encourages non-recycling of large sum of the GDP back into the economy, thus
leading to unemployment as well as a very unstable CPI (Soros, 1998; Yergin & Stanislaw,
1998).
The battle between government and the marketplace that is remaking the modern world seems to
be tilted towards the side of government mainly through government regulations, tariffs as well
as other infringements on pure system of free market (Yergin & Stanislaw, 1998). Thus there has
been emphasis on the futility of utilizing monetary policies that are inflationary by the
governments in order to influence the rates at which the economy grows. Moreover, this battle
has continued through income tax reforms and policies through expansion of rebates tax write-
offs, and subsidies as a way of titling the markets (Yergin & Stanislaw, 1998).
In order to have effectively working global economy there needs to be adoption of alternative to
the free market system in capitalism which would encourage smaller governments with tighter
price controls alongside increased minimum wage in helping to solve some of the CPI problems
(The Economist, 1998). Thus, free market system in capitalism needs to be blended with other
systems such as the socialism and collectivization, in the attempts of creating a fairly decent
economy without vicious cycles of deflation, inflation, financial crises as well as unemployment
(Kissinger, 1998).
Question three
Global Decision Making 10
a. A steady state economy is an economy structured to balance economic growth with
population growth whereby it seeks to find equilibrium between population growth and
production growth. In a steady state economy the rate of GDP growth should be equal to
the rate of population growth (Krugman & Wells, 2006).
b. In Neoclassical growth model the reason why an increase in the savings rate does not
increase the growth rate of per capita output in the long run is because a higher saving
rate does result in a higher steady-state capital stock and a higher level of output mainly
because there is no investment in technology and labor which are two significant factors
attributable to long-term growth rate of per capita.
c.
- An increase in the rate of growth of the population, n, reduces the steady state level of
k and y because the population is growing at a rate higher than the rate at which the
GDP and per capita are growing eventually failing to sustain them causing them to
reduce (Krugman & Wells, 1989). - An increase in population increases the steady state rate of growth of aggregate
output mainly because the output of the entire population is considered. Hence since
increased population provides labor then the aggregate output is increased (Krugman
& Wells, 2006).
(i) A decrease in population increases the steady state level of k and y because the
country produces more than it consumes and the surplus is used to invest in
technology eventually increasing the GDP and per capita.
Global Decision Making 11
(ii) A decrease in population decreases the steady state rate of growth of aggregate output
mainly because there is a decrease in labor which is most significant factor
attributable to aggregate output (Krugman & Wells, 2006).
