Up to this point, all of our explanations of foreign economic policy have centered
around political variables: the structure of the international system and
policymakers’ ideas, interests, and institutions.
But markets also constrain and enable policymakers.

Remember that Smith & Rogowski argued that interest groups lobby
policymakers to secure policies that benefit them.
Interest groups’ lobbying power, however, depends to some extent
on their economic status.6

Wealth brings status and power.
At a minimum, markets influence the strength of societies’ various
interest groups.

Remember that market actors often enjoy exit options.
If they don’t like certain policies, they can frequently work around them or even relocate to other
jurisdictions.

Because states fret at the potential loss of these valuable actors, policymakers are somewhat beholden to market actors.
Market actors can thus reward and punish certain types of
behavior.10

Example: Sovereign Debt
• Sovereign has the power to repudiate debt• Lenders have several possible responses
– Raise interest rates– Refuse to lend– Hide assets– Emigrate
• By consistently repaying debts, sovereign ensures larger supply of capital and better terms (lower interest rate)

If market actors find policy completely noxious, they may take action—deliberate or indeliberate
—that negates state policy.

Example: Avoiding Taxes
• Hoping to increase tax revenues, a state raises its income tax
• Most citizens acquiesce since the costs of circumventing the law outweigh the benefits
• But the richest citizens have the most to lose and can emigrate at the lowest cost
• Ultimately, the state’s revenues decrease as the richest citizens leave and no longer pay any tax

The “balance of payments constraint” is one of the most
significant constraints policymakers face when setting
foreign (and domestic!) economic policy.

But it is also the most difficult to understand!
It can be a bit abstract and complex, but we need to
understand it.

Learning Objectives
1. Familiarity with the major components of the BoP
2. Understand constraints imposed by the BoP3. Identify policymakers’ options for managing
the BoP
We’ll revisit the BoP frequently throughout the term!

What is the balance of payments (BoP)?
23
![Page 24: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/24.jpg)
The balance of payments (BoP) reconciles all of a country’s financial
transactions with the world.
This includes trade, remittances, investment, loans, &c.
As an accounting matter, the BoP must always balance, by design.
24
![Page 25: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/25.jpg)
But that balance can be achieved in more or less painful ways…
that balance can be achieved with more or fewer implications for other
policy areas.

Let’s look at an actual year (1997) for the US.
(This is detailed in Grieco & Ikenberry, Ch 3.)

So, what about the extra $84.7 billion?
![Page 32: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/32.jpg)
Well, much of this is explained by statistical discrepancies.
Governments recognize that they can’t get fully accurate reporting on all
of these transactions.
In 1997, the US statistical discrepancy was estimated at $99.7 billion.
32
![Page 33: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/33.jpg)
33
But that still leaves $14.8 billion!!! I thought the balance of payments
always balances!
![Page 34: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/34.jpg)
34
It does--but often not without some help!

Milton Friedman describes the various mechanisms available to states to redress imbalances of
payments. (p 202)

Relieving Pressure on the Balance of Payments
1. Adjustment of Reserves2. Adjustment of Internal Prices & Incomes 3. Exchange Rate (ER) Adjustment4. Exchange Controls
38
![Page 39: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/39.jpg)
(1) Adjustment of Reserves
• The first option is to “adjust reserves” using “official transactions”
• Reserves: non-domestic financial assets (foreign currency, bonds, &c.) held & used by govts to support their currency
• Official Transactions: govt purchase/sale of foreign reserves so as to alleviate pressure on the balance of payments 39
![Page 40: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/40.jpg)
Example: US in 1997• Foreign central bank purchases of US currency &
US treasury bills & bonds: $15.8bn• US holding of foreign currency & government
debt: -$1bn
US & Foreign official transactions account for the missing $14.8 billion
40
![Page 41: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/41.jpg)
41
Oh, that must be nice: you can clear your imbalances just by
adjusting your reserves!
That does sound nice. But is there any limit to
the amount of “adjusting” you can do?
![Page 42: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/42.jpg)
Asymmetric Options• Selling Reserves
– A central bank cannot sell more reserves than it has initially
• Amassing Reserves– There is, theoretically, no upper limit to the quantity of
reserves a central bank can acquire– A central bank can purchase limitless foreign currency by
continually printing and selling its own currency in exchange
– To prevent inflation, it might employ sterilization: selling govt bonds and “soaking up” excess currency
This is precisely what China has been doing.42
![Page 43: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/43.jpg)
Returning to the US BoP in 1997, we’re all set:
The official transactions and “statistical discrepancy” resolve the US autonomous surplus of
$84.7 billion.
43
![Page 44: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/44.jpg)
But Friedman listed three other mechanisms that can be used to
maintain balance.
These mechanisms, however, work dynamically—so we don’t
always see their effects on the balance sheet.
44
![Page 45: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/45.jpg)
(2) Adjustment of Internal Prices & Incomes
• Central bank influences domestic rate of interest (RoI)
• Double effect of RoI adjustments1. Influences domestic price level current
account2. Influences int’l capital flows capital account

BoP Adjustment via Interest Rate Changes
46

(3) ER Adjustments
• Mechanism 2 maintained the external value of currency (the ER) at the expense of adjusting the internal value (the domestic price level)
• Mechanism 3 does the opposite: maintain the domestic price level but allow the ER to adjust
47

(4) Exchange Controls
• State directly manages the current and/or capital account
• Current Account Intervention: management of trade & commerce– Subsidies, tariffs, restrictions, &c.

Current account intervention directly adjusts the costs of
domestic/foreign transactions.
Capital account intervention indirectly adjusts these costs by
influencing the costs of acquiring the foreign currency required for
foreign transactions. 51

So, we have 4 different options…
But don’t make the mistake of assuming that all of these
responses are equal!!

“It cannot be too strongly emphasized that the structure and method of determining exchange rates
have a vital bearing on almost every problem of international economic relations…The only other
alternative to movements in exchange rates is direct control of foreign trade. Such control is therefore
almost certain to be the primary technique adopted to meet substantial movements in conditions of
international trade so long as exchange rates are maintained rigid. The implicit or explicit recognition of this fact is clearly one of the chief sources of difficulty
in attempts to achieve a greater degree of liberalization of trade in Europe…” (Friedman, 196-197)

Friedman, in fact, was following JM Keynes…

![Page 57: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/57.jpg)
“The problem of maintaining equilibrium in the balance of payments between countries has
never been solved…So far from currency laissez-faire having promoted the
international division of labour, which is the avowed goal of laissez-faire, it has been a
fruitful source of all those clumsy hindrances to trade which suffering
communities have devised in their perplexity as being better than nothing in protecting them
from the intolerable burdens flowing from currency disorders.”
-- Keynes (1941)57

So, what does Friedman propose?
58
![Page 59: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/59.jpg)
“There are no major economic difficulties to prevent the prompt establishment by
countries separately or jointly of a system of exchange rates freely determined in open markets, primarily by private transactions,
and the simultaneous abandonment of direct controls over exchange transactions. A move
in this direction is the fundamental prerequisite for the economic integration of the free world through multilateral trade.”
(MF, 203)59

So, policy makers have a variety of ways to ensure that their payments
balance.
And prominent theorists (Keynes; Friedman) suggest that some of those choices (flexible ERs) are better than
others (exchange controls).

“In my view…it is impossible to understand this crisis without
reference to the global imbalances in trade and capital flows that began in the latter half of the
1990s.”-- Ben Bernanke, Speech at the Council on Foreign Relations.
(March 2009)

We thus face two questions with extraordinary contemporary relevance:
(1) what causes imbalances of payments in the first place?
(2) what are the effects of sustained imbalances?

Doug Irwin has developed one perspective on this vital question:
65
![Page 66: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/66.jpg)
“Trade policy cannot directly affect the current account deficit because trade
policy has little influence on the underlying determinants of domestic savings and
investment, the ultimate sources of the current account. If a country wishes to
reduce its trade deficit, then it must undertake macroeconomic measures to
reduce the gap between domestic savings and investment.”
(D Irwin, Free Trade Under Fire, 90)

Hmm. Interesting.
Now compare that to this…

“When a country is growing in wealth somewhat rapidly, the further progress of this happy state of affairs is liable to be
interrupted, in conditions of laissez-faire, by the insufficiency of the inducements to new investment…the opportunities for home investment will be governed, in the long run, by the
domestic rate of interest; whilst the volume of foreign investment is necessarily determined by the size of the
favourable balance of trade…At a time when the authorities had no direct control over the domestic rate of interest or the other
inducements to home investment, measures to increase the favourable balance of trade were the only direct means at their
disposal for increasing foreign investment; and, at the same time, the effect of a favourable balance of trade on the influx of the precious metals was their only indirect means of reducing
the domestic rate of interest and so increasing the inducement to home investment.” (Keynes, General Theory, 335-336)

What is the relationship each theorist sees between
macroeconomic (monetary) policy, the patterns of investment &
saving, and the balance of trade (the current account)?

![Page 70: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/70.jpg)
Irwin versus Keynes
• Irwin– Macroeconomic policy patterns of saving &
investment balance of trade• Keynes
– Balance of trade patterns of saving & investment macroeconomic effects (on domestic price level)
The causal chains are reversed!

This directly relates to the current global financial crisis.
What caused the housing bubble that ripened conditions for the
crisis?

China & Germany Follow Irwin’s Perspective
• US has loose monetary policy; Germans & Chinese have tight monetary policy US savings rates fall German & Chinese savings rates rise
• An abundance of US capital causes Americans to buy more of everything
Because interest rate is low, US consumers buy houses rather than invest in businesses; this caused the housing bubble 73
![Page 74: Economic Constraints: The Balance of Payments Lec 6 – Thursday, 29 September 2011 J A Morrison 1 Milton Friedman (1912-2006)](https://reader030.vdocuments.site/reader030/viewer/2022032723/56649d165503460f949ec24a/html5/thumbnails/74.jpg)
US Follows Keynes’ Perspective• US has excess demand for Chinese goods
negative BoT• US: this should either appreciate the ER or raise
prices in China, which would correct the imbalance
• BUT China limits appreciation and inflation– it absorbs USD into reserves ($1.3 trillion) and
sterilizes RMB to limit inflation• Glut of capital in China Chinese savings rate• Speculative flows from China US housing
bubble• Limited appreciation of RMB US trade deficit

Our theory of the cause of these imbalances will determine the policies we
undertake in the current crisis…
Germany insists that the US tighten monetary policy.
The US insists that the surplus countries (China & Germany) allow their ERs to
appreciate.75
