INTRODUCTION
Fiscal and monetary policies are two macroeconomic policies that governments employ to affect domestic output, maintain full employment and price stability
These are the 2 macroeconomic policies used to achieve the 3 goals of any economic policy
These polices have an effect on the exchange rate, the current account, interest rates, and short-run capital flows within an environment of floating exchange rates

FISCAL AND MONETARY POLICY
Fiscal policy entails using changes in government taxation and/or spending to affect the level of economic activity GDP
Monetary policy uses changes in the money supply and/or interest rates to affect a county’s GDP
Changes in these policies have predictable effects on the exchange rate, the current account balance, and short-run capital flows

FISCAL AND MONETARY POLICY
In this chapter (Ch18) we’ll assume these policies are conducted in a floating exchange rate regime ERR (effects in a fixed ERR are in Ch19)
The assumption is that the government does not employ fiscal and/or monetary policy in an attempt to generate a balanced current account, but to affect the output and price level

FISCAL AND MONETARY POLICY
It used to be common practice for governments to focus fiscal and/or monetary policy on obtaining what is known as an external balance
Governments now tend to use monetary and fiscal policy to focus on a country’s internal balance
Internal balance refers to the levels of unemployment and inflation that fit the preferences of the citizens of various economies
The focus on internal balance comes at the expense of external balance considerations
Policies designed to achieve a desired internal balance may have large consequences for a country’s external balance

CHANGES IN FISCAL POLICY
In most countries, government spending is such a large part of the GDP that any changes can have a critical impact on an economy
Substantial amounts spent on transfer payments mean tax revenues add to this amount
A portion of total government spending is usually financed through borrowing, thereby having a significant impact on country’s domestic financial markets and interest rates

CHANGES IN FISCAL POLICY
The demand for loanable funds is the total demand for loans in the economy
It includes private sector demand from the public’s consumption activities that must be financed and business demand for funds for investment
The public sector demand is generated by the government’s need for funds which is the difference between total government spending and total taxes collected
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
CHANGES IN FISCAL POLICY
The supply of loanable funds represents the total amount of money available to be borrowed by the private and public sectors of the economy
This is represented as perfectly inelastic; the amount of loanable funds is not related to the interest rate
In the short-run, the amount of money held in savings by the public determines the supply of loanable fund

CHANGES IN FISCAL POLICY
Expansionary Fiscal Policy
The government adopts an expansionary fiscal policy by choosing to lower tax revenues and/or have higher government spending
This leads to a government budget deficit (or larger deficit)
Assume government borrows to finance and does not print money
This will have a predicable effect on interest rates as in Fig 18.1
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
CHANGES IN FISCAL POLICY
An expansionary fiscal policy causes an increase in the demand for loanable funds (from D to D’)
In a closed economy, this would cause interest rates to rise (from ie to i’)
In an open economy with freely flowing international capital, the rise in interest rates causes an inflow of capital and an increase in the supply of loanable funds (from S to S’)
This inflow of capital lowers domestic interest rates (from i’ back to ie)

CHANGES IN FISCAL POLICY
The net result of an expansionary fiscal policy in an open economy is that less upward pressure is put on interest rates than would be the case in a closed economy
A larger federal government budget deficit tends to increase domestic interest rates which causes an inflow of foreign capital into the country
The capital flows have an effect on the equilibrium exchange rate (as described in Ch15)
This effect is shown in Fig. 18.2

CHANGES IN FISCAL POLICY
In an economy with a balanced current account, if the government adopts an expansionary fiscal policy and domestic interest rates rise, the inflow of foreign capital requires foreign investors to sell foreign currency to buy dollars
The supply of foreign exchange increases (from S to S’) and the nominal exchange rate appreciates (from XRe to XR’)
The capital inflows encouraged by the higher interest rates will result in a capital account surplus and a current account deficit (M-X at XR’)
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
CHANGES IN FISCAL POLICY
Therefore, an expansionary fiscal policy puts upward pressure on domestic interest rates which leads to an increase in the flow of capital from abroad into the domestic financial markets leading to an appreciating currency and a current account deficit
However, we need to consider the effect of an expansionary fiscal policy on the domestic economy (using tools of AD and AS from Ch17)?
In a closed economy, this would lead to an increase in domestic output and price level

In an open economy, the effects are less clear as an expansionary fiscal policy has two conflicting effects
The policy increases AD as the government reduces taxes and/or increases spending –the direct effect
On the other hand, the policy reduces AD as the exchange rate appreciates and the current account balance deteriorates – the indirect effect

CHANGES IN FISCAL POLICY
Contractionary Fiscal Policy
A contractionary fiscal policy would entail some combination of higher taxes and/or lower government spending
This reduces a government budget deficit or increases size of a surplus
Adopting a contractionary fiscal policy causes the overall demand for loanable funds to shrink (from D to D’) and lowers the interest rate (from ie to i’)

CHANGES IN FISCAL POLICY
The lower domestic interest rate affects capital flow into the country as domestic and foreign investors would tend to invest less domestically and domestic investors would tend to invest more capital abroad
The net result would be an outflow of capital from domestic economy and the supply of loanable funds would decrease (from S to S’) raising interest rates (from i’ back to ie)
A contractionary fiscal policy puts less downward pressure on domestic interest rates in an open economy than in a closed economy

CHANGES IN FISCAL POLICY
A contractionary fiscal policy lowers the federal government budget deficit which decreases domestic interest rates and causes an outflow of capital
This increases the demand for foreign exchange (from D to D’) and the exchange rate rises or the domestic currency depreciates (from XRe to XR’)
This causes the capital account to become negative which causes the current account to become positive (X-M at XR’)
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall

CHANGES IN FISCAL POLICY
Therefore, a contractionary fiscal policy puts downward pressure on domestic interest rates which leads to an decrease in the flow of capital from abroad into the domestic financial markets leading to an depreciating currency and a current account surplus
What about the effects in a closed vs. open economy?
In a closed economy, this would lead to an decrease in domestic output and price level

A contractionary fiscal policy in an open economy is less effective in changing equilibrium output than it is in a closed economy

CHANGES IN FISCAL POLICY
The net effect depends on the magnitude of the two effects
Conclusion: In open economies with international capital mobility, contractionary fiscal policy is not as particularly effective in changing the equilibrium levels of output & prices
Fiscal policy can still, however, affect interest rates, exchange rates, capital flows and current account balances and the effects are noticeable in the economy and have an effect on business decision making

CHANGES IN MONETARY POLICY
Most central banks in developed countries use discretionary monetary policy in an attempt to affect the short-run performance of the economy by changing the growth rate of the money supply and/or interest rates
Our interest is in explaining the effects of changes in monetary policy on exchange rates, the current account and by extension on a country’s overall economy
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
CHANGES IN MONETARY POLICY
Expansionary Monetary Policy
An expansionary monetary policy results when a central bank increases the money supply or money supply growth rate
Increases in the money supply increase the supply of loanable funds (from S to S’) initially causing a decrease in the interest rate (from ie to i’)
The decrease in interest rates causes a capital outflow

CHANGES IN MONETARY POLICY
Capital outflows cause demand for foreign exchange to increase (from D to D’) and the currency depreciates (from XRe to XR’) which worsens the capital account causing a deficit
This translates into a current account surplus as exports increase and imports decrease (X-M at XR’)
An expansionary monetary policy indirectly leads to a current account surplus when capital is mobile between countries

CHANGES IN MONETARY POLICY
In a closed economy, monetary policy is generally effective because lower interest rates increase both consumption and investment spending—the direct effect
AD increases (shifts from AD to AD’)
In an open economy, the fall in interest rates induces depreciation of the domestic currency and capital outflow improving the current account as exports increase and imports decrease—the indirect effect
The AD curve shifts even further to the right (from AD’ to AD’’)

CHANGES IN MONETARY POLICY
These movements in the exchange rate, the financial account and the current account tend to reinforce the initial effects of monetary policy on the domestic economy
Conclusion: The net result is that in an open economy with capital mobility, monetary policy is effective in increasing the level of economic activity (influencing output and price levels)

CHANGES IN MONETARY POLICY
Contractionary Monetary Policy
In contractionary monetary policy, the central bank decreases the money supply or reduces the money supply growth rate
The most notable effect is an increase in domestic interest rates
In developed countries, decreasing money supply is done through selling government bonds, which decreases the supply of loanable funds (from S to S’) causing a rise in interest rates (from ie to i’)

This increase in domestic interest rates attracts foreign capital
In order to buy domestic financial assets, foreign investors must sell foreign currency and buy domestic currency in the foreign exchange market
The capital inflow will increase the supply of foreign exchange (from S to S’) causing a decrease in the exchange rate (from XRe to XR’)
This creates an exchange rate appreciation

The capital inflows and appreciating exchange rate create a capital account surplus and a current account deficit (M-X at XR’)
What about the effects in a closed vs. open economy?
In a closed economy, a contractionary monetary policy is effective because the increased interest rate reduces the growth rate of consumption and/or investment
The reduction in total spending causes a decrease in AD lowering output and the price level
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
CHANGES IN MONETARY POLICY
In an open economy, the effects are larger. Why?
The initial effect of a contractionary monetary policy is to decrease AD – the direct effect
The increase in interest rate induces capital flows into the country and an appreciation of the currency
The current account deteriorates as exports fall and imports rise—the indirect effect
Conclusion: In an open economy with free international capital mobility, contractionary monetary policy is highly effective in changing equilibrium levels of output and price

MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
The effects of government policies are often described in terms of effects on a country’s external and internal balances
The current account balance represents the external balance while the equilibrium level of output and price level is the internal balance
At any point in time, there is an optimal balance of output level and price level implying full employment and stable prices
This is rarely observed
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
Governments frequently use fiscal and monetary policy to achieve an acceptable balance between output and price level
Fiscal and/or monetary policy can be used to influence internal or external balance
In many cases, governments cannot balance both and have to choose which is more important
Typically internal balance is seen as most important and fiscal and/or monetary policy is focused on achieving an optimal internal balance
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
Although both fiscal and monetary policy affect the current account and exchange rates, they are usually not the primary focus of policy
The public and the press tend to think the exchange rate and the current account are the primary targets of macroeconomic policies
While this may be the case, macroeconomic policy is often focused on a country’s internal balance
The policy mix of a country is the effects of various combinations of fiscal and monetary policy

MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
Consistent Policy Mixes
In a recession, the real GDP is below the full employment level
The government wants to increase output by adopting an expansionary monetary policy and/or expansionary fiscal policy
A combination of both would tend to increase output and price level
The potential for rising prices may be deemed an acceptable risk
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
The effect on the exchange rate is unclear depending on magnitude of change in the two policies on domestic interest rates
The effect on the current account is also unclear depending on the effect on interest rates
From a policy perspective, battling a recession and letting the external balance adjust as needed is a safe option
The domestic economy would improve and the external balance is unlikely to change by a large amount in either direction
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
A similar scenario emerges if the problem is inflation
The economy is temporarily producing output at greater than full employment levels
The government would employ a combination of contractionary monetary and fiscal policies
The effects on internal balance are that both equilibrium output and the price level would fall
The effects on the external balance (exchange rate and current account) are unclear since policies move in opposite directions
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
This policy mix does not appear to be a problem as the internal balance moves in the desired direction without dramatic changes in the external balance
When governments adopt similar fiscal and monetary policies, the equilibrium level of output and the price level (internal balance) can be changed without making drastic changes in the exchange rate or current account balance (external balance)

18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
Inconsistent Policy Mixes
Mixtures of fiscal and monetary policies that are inconsistent with one another (one expansionary, the other contractionary) are inconsistent with internal balance objectives
Why would a government adopt such a mixture when the effects are unclear?
Often different policy makers are in control of fiscal and monetary policy
In the U.S., elected officials control the fiscal policy while the independent Federal Reserve determines the monetary policy
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
The effect of inconsistent policies can be ambiguous on the domestic economy (internal balance)
However, the effect on the external balance is explicit (see Table 18.1)
An expansionary fiscal policy and contractionary monetary policy leads to an appreciation of the currency and decreased current account
The policies reinforce one another and the effect on the external balance can be significant
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
MONETARY AND FISCAL POLICY IN AN OPEN ECONOMY
Similarly, a contractionary fiscal policy coupled with an expansionary monetary policy leads to a depreciation of the domestic currency and an improvement in the current account balance
The point of our discussion is that inconsistent policy mixes can have extreme effects on a country’s external balance
The effect of changes in the country’s exchange rate can have a dramatic impact on the competitiveness of individual firms with tradable goods

Implicit in our analysis was an assumption of no lag in the effects of monetary and fiscal policies on macroeconomic variables
If financial markets are relatively efficient, then interest rates are affected quickly
Moreover, high capital mobility allows the exchange rate to change relatively quickly
However, the response of trade flows to changes in exchange rates may not always happen quickly
TRADE FLOW ADJUSTMENT AND CURRENT ACCOUNT DYNAMICS

18 – ‹#›
The price of imports and exports may not change instantly as the exchange rate changes
International trade may respond slowly to changes in prices compared to the response of financial markets
The time it takes for the exchange rate to affect a country’s exports and imports and the current account balance may be as long as six months to a year
TRADE FLOW ADJUSTMENT AND CURRENT ACCOUNT DYNAMICS
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall

In the long-run, as a country’s currency depreciates, its exports expand and imports contract (and vice versa)
In the short-run, as a country’s exchange rate changes, the response of exports and imports and current account balance could very easily be in the opposite direction
In part, this is because international trade is often conducted between parties on a contract basis
TRADE FLOW ADJUSTMENT AND CURRENT ACCOUNT DYNAMICS

Also, in the short-run, demand for the more expensive imports (and demand for exports, which are cheaper to foreign buyers using foreign currencies) remain price inelastic
This is due to time lags in the consumer's search for acceptable, cheaper alternatives
The net effect is that the current account may initially worsen after a depreciation and only improve after a lag

The effect on the current account balance has been called the J-curve
This reflects the tendency for the current account balance to initially worsen when a currency depreciates
Only after contracts are renewed to reflect the new exchange rate will the current account begin to improve
It is important for policy makers to take the lag effect into account

Governments use fiscal policy to change the level of taxation and/or government spending at the national level to affect the level of economic activity (GDP). Governments use monetary policy to change the money supply or interest rates to affect a country’s level of economic activity.
A country’s exchange rate and its current account balance represent its external balance
Expansionary fiscal policy occurs when a government chooses to adopt some combination of lower tax revenue and/or higher government spending
SUMMARY
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
In an open economy with international capital mobility, expansionary fiscal policy leads to a rise in interest rates which causes and inflow of foreign capital
A contractionary fiscal policy in an open economy is not very effective in reducing the price level or real GDP
Expansionary monetary policy occurs when a government chooses to increase the money supply or the money supply’s growth rate
SUMMARY
Copyright © 2009 Pearson Education, Inc. Publishing as Prentice Hall
18 – ‹#›
In an open economy with international capital mobility, expansionary monetary policy leads to a fall in interest rates which causes an outflow of foreign capital
A contractionary monetary policy would lead to higher interest rates, lower output, and a lower price level
Consistent policy mixes can be effective in solving internal balance problems
