Macroeconomic policy in an open economy

Fiscal policy:

 definition, how conducted effect on interest rates and inflation effect on exchange rates and balance of payments

Monetary policy

 definition, how conducted effect on interest rates and inflation effect on exchange rates and balance of payments

We will not consider aggregate demand/aggregate supply effects

Fiscal policy

Keynes: the government should

 deliberately incur deficits when the economy is in

 recession, so as to stimulate demand incur surpluses when the economy is booming, so as to dampen demand

His deficit prescription was very popular with politicians, business people, taxpayers – a free lunch!

Surplus prescription largely forgotten

Effects of fiscal stimulus on loanable funds market

Increased spending must necessarily be financed by borrowing

 If it were financed by taxation, there would be no stimulative effect, just a wealth transfer from taxpayers to politicians

Causes outward shift in the demand curve for loanable funds

Raises interest rates, other things equal

Crowds out marginal private borrowers

The supply of loanable funds is not perfectly inelastic as Fig. 18.1 suggests: higher interest rates encourage saving

Deficits do not cause inflation

Deficit spending does not in itself increase the money supply, so there is no money inflation

There could be a minor price deflation as people are induced to save more by higher interest rates, meaning they demand fewer consumption goods

Deficits indirectly lead to price inflation when central banks soak up some of the new bond issues using newly created money

Effects of expansionary fiscal policy on exchange rates

Higher interest rates attract capital from abroad, e.g. UK investors who must change

£ into $

In $/£ forex market, the supply of £ rises and the $/£ XR drops

Also US investors are less inclined to invest in UK, therefore demand for UK£ drops, and this further suppresses the $/£ XR

Lower $/£ XR due to fiscal stimulus

A lower $/£ XR (appreciated $) is (in the short run)

 bad for US export industries since exports cost more for UK buyers (in terms of £) good for US consumers since UK imports cost

 less (in terms of $) good for UK producers who face reduced competition from US producers bad for UK consumers for whom imports from

US cost more

Public choice theory says the US producers have a louder voice & will complain to their politicians: “We are bearing an unfair burden!”

Summary of effects of fiscal policy on international trade

Expansionary fiscal policy

 Loanable funds market

Increased demand (to cover deficit) raises interest rate

Higher interest rate boosts capital inflow, discourages outflow

Capital account improves, current account worsens

Increased supply of foreign currency to buy US securities suppresses XR

Reduced demand for foreign currency to acquire foreign securities further suppresses

For our example, $/£ falls, meaning the US$ appreciates)

Inflation

No direct effect

Contractionary fiscal policy

 Everything is reversed

Monetary policy

Central banks now monopolize the business of supplying money

Our money is purely fiat money meaning that it is not even indirectly related to any commodity (gold or silver)

The Fed engages in discretionary monetary policy (as distinguished from a rule-based policy)

 The Fed chairman, Alan Greenspan, was thought to be a wizard until the 2007 collapse

 The Fed expands the money supply when it believes this necessary to stimulate the economy

Expansionary Monetary Policy

The Fed expands the money supply (money inflation) by buying Treasury securities from

New York bond dealers using newly created money (“open market operations”)

Fed expansionary policy constitutes an increase in the supply of loanable funds

(supply curve should not be inelastic as in

Fig. 18.7)

Drives down interest rate

Encourages business borrowing which is supposed to revive the economy

Summary of effects of monetary policy on international trade

Expansionary monetary policy (cont’d)

 Inflation

Money inflation results in price inflation (falling PPM)

Price inflation makes US goods less attractive to foreigners, and foreign goods more attractive to US people

Supply of foreign currency drops, demand rises

XR rises, US$ depreciates loanable funds market

New money created by the Fed enters the bond market, supply of loanable funds rises

Interest rate falls

 Foreigners less interested in US securities, US

 people more interested in foreign securities

Demand for

Summary of effects of monetary policy on international trade

Expansionary monetary policy (cont’d)

 Inflation

Increased supply of loanable funds (newly created

Fed $) suppresses interest rates

Lower interest rate means some capital goes to foreign countries

Capital account worsens, current account improves

Reduced supply of foreign currency from foreigners wanting US capital assets, and increased demand for foreign currency by US people, raises XR of foreign currency (e.g. $/£, falls, meaning the US$ depreciates)

 Inflation

No direct effect

Contractionary monetary policy: everything is reversed

How all of this complication could vanish

Replace central banking with free banking where private banks issue money in response to user demand.

 Government monetary policy ceases to exist

Try to maintain a balanced budget at all times

 Government fiscal policy ceases to exist

As more countries adopt free banking, market forces would push money issuers toward a common standard

 XR issues would cease to exist

Domestic stimulus or currency war?

Expansionary monetary policy as we have seen depreciates a country’s currency

Open question: were recent expansionary monetary actions (Japan, U.S.) intended to stimulate the domestic economy generally or were they specifically trying to boost export industries, thus inviting retaliation?

The J Curve

Devaluation of a country’s currency leads to expansion of exports and an increase in its current account balance (increased surplus or decreased deficit)

The short run effect may be in the opposite direction. Why?

 Exporters may have long-term commitments to

 sell at a particular price. Those terms may be renegotiated later, and increased production comes on line only later

But import prices rise immediately

Net short-term effect: worsened current account
