• To ensure the world’s scarce productive resources (factors) to be fully employed.
1. Unemployment (no idle)
2. Saving (equal to income)
3. Trade imbalances (export = import; wealth)
4. Money and the price level(medium; spill over)

• Equilibrium vs. Balance (Condition)
• EquilibriumEquilibrium: a condition that all influences are canceled by others, resulting in a stable, balanced, or unchanging system.
• BalanceBalance: a state of equilibrium or parity
Y: National IncomeY: National Income
Y=GNP – depreciation + net unilateral transfer
– indirect business taxes
(GNP = GDP + net receipts of factor income from rest of world)
(closed economy)
Imports from abroad add to foreign countries’GNPs, but do not add directly to domestic GNP

Balance of PaymentBalance of Payment
Any transactions:
A Payment go foreigners(outflow of money)
A Payment go foreigners(outflow of money)
A Receipt from foreigners(inflow of money)
A Receipt from foreigners(inflow of money)
Debit (--)Purchase of assets (capital account)
= importing
Debit (--)Purchase of assets (capital account)
= importing
Credit (+)Sales of assets
(capital account)= exporting

Double-entry Double-entry bookkeeping rulesbookkeeping rules
• Every international transaction automatically enters the balance of payment twice: once as a credit and once as a debit.
• (i.e., you pay a foreigner for goods you buy; then the foreigner spend or store the amount you paid.)
Example 1:Example 1:
• Chinese firm exports wheat paid for by transfer to domesticdomestic bank account:
• [+] entry in “Exports” of Current AccountCurrent Account
• [- ] entry in Non-Official Portfolio Investment in Capital AccountCapital Account.
Example 2:Example 2:• US Fund buys RMB 100 million Haier sharshar
eses using Chinese bank deposits.• In this case there are no goods/services flow
s so there is no entry in the current account• Two capital account transactions:• [+] entry in Portfolio Investment• [- ] entry in Portfolio Investment
IMF’s category of BOP .1IMF’s category of BOP .1
• Balance of Payment is a statistical statement for a given period showing :(a) transactions in goods, services, and income between an between an economyeconomy and the rest of the world;(b) changes of ownership and other changes in that economy’s monetary gold, special drawing rights (SDRs) and claims on and liabilities to the rest of the world;

• and (c) unrequited transfers and counterpart entries that are needed to balance, in the accounting sense, any entries for the foregoing transactions and changes which are not mutually offsetting.
• ---- adapted from Balance of Payment Statistics Yearbook 1989, IMF
Krugman:Krugman:
• A country’s balance of payments is net purchases of foreign foreign assets by the home central bank less net purchases of domestic assetsdomestic assets by the foreign central banks.
BOP has the following elements:BOP has the following elements:
- It is a statistical statement
- of all economic transactions
- between the residents and non-residents
