Suggested answer to case study discussion question
What Role for Gold?:Probably not. Internal balance is achieved by
maintaining a reasonable level (and growth rate) of GDP so that the county
has a reasonable (probably fairly low) unemployment rate and an acceptable
(probably fairly low) rate of product price ination. Macroeconomic shocks hit
a country’s economy from time to time. Some of these shocks reduce
aggregate demand and lead to recessions and rising unemployment. Some
of these shocks expand aggregate demand excessively and put upward
pressure on domestic prices and the country’s ination rate. A national
government has three types of macroeconomic policy that can be used to
pursue internal balance. The national government generally can use
monetary policy, (scal policy, and exchange rate policy. A new gold standard
would obligate the central banks of countries who choose it to defend the
(xed price of gold by buying and selling gold at the (xed price. If the
country’s central bank is fully committed, then this is a rather strong form of
(xed exchange rates, because the exchange rates among the currencies of
the countries on the gold standard are implied by the (xed gold prices.
Exchange rate policy cannot be a major tool to pursue internal balance. And,
monetary policy is also not a major tool to pursue internal balance, because
the central bank alters the country’s money supply in response to changes in
gold supply and demand, rather than in response to shock-driven shifts in
aggregate demand and GDP. Fiscal policy is still available as a tool for the
government to pursue internal balance, but in many countries (scal policy is
the least exible or the most politicized tool.

1. Disagree. Countries must follow policies that are not too different if they are to be able to
maintain the fixed exchange rates. The policies need not be exactly the same, but the
policies must lead to private demand and supply in the foreign exchange market that
permits the countries to defend the fixed rates successfully. The most obvious need for

2. Probably agree, but with a caution. It is usually argued that the average rate of global
inflation would tend to be lower if most countries adhered to a system of fixed exchange
rates. Countries that succeed in maintaining fixed exchange rates among their currencies
3. A oating exchange rate provides some insulation from foreign
business cycles because the rate tends to change in a way that
counters the spread of the business cycle through international trade.
4. Agree or disagree. If you say agree, then you will emphasize points like the following.
With a clean floating exchange rate, the rate is set by private competitive supply and
demand in the market. This rate is a market price that represents all information about

5. Possible criteria include the following. First, if the country wants to shift
to a (xed exchange rate to promote international trade by reducing
exchange-rate risk, then it should consider (xing its exchange rate to
the currency of one of its major trading partners. Second, the country
should look for a country whose priorities and policies are compatible
6. a. These economists believe that the variability exists for good reasons, and that many of
the supposed bad effects of exchange rate variability are not that large. They believe that
the variability results from rational and reasonable responses of market participants,
especially international investors, to various kinds of shocks and news. As economic and
b. These economists believe that the variability is excessive, and that the risks do have an
undesirable impact on international transactions. They believe that the variability
sometimes results from bandwagons and similar expectations that carry exchange rates
away from their appropriate economic values. In addition, overshooting can cause

aggregate demand. The reduction in aggregate demand will create the

Adopting a currency board and a (xed exchange rate with one of
these currencies may help the country reduce its ination rate for
several reasons. First, the country is accepting the discipline e2ect of
