28 Balance of Payments: Crisis and Balancing Mechanisms A BOP crisis (currency crisis) occurs when a nation is unable to service its debt repayments and/or to pay for essential imports. It generally is coupled with a fast depreciation of home currency. General Mechanism: Large Capital Inflows over Time (either due to finance high economic growth, in this case to finance investment / or due to excessive consumption, in this case to finance consumption ( and lower savings)) unsustainable levels of debt creates a chain of events: investors pull out their funds by selling domestic currency denominated assets causing rapid depreciation of home currency Local banks and firms run in to sudden debt problems because their revenues are in local currency but their existing debt is in foreign currency the central bank can support the currency as long as it has enough FXreserves, but once reserves fall below a certain level chooses to increase interest rates to prevent outflows prevents currency depreciation and reduces the value of debt in domestic currency however, the domestic economy is depressed recession follows.

49 Law of One Price Definition The law of one price: Two goods, if they are identical, must sell for the same price. Domestic Economy The law of one price in the context of domestic economy the relationship holds if transaction costs are allowed: e.g., P I = P A + C where P I, P A is the price of the same good in Istanbul and Ankara respectively and C is the transaction cost (transportation, local taxes, etc.). zan Hatipoglu (Department of Economics) Open Economy Macroeconomics Spring / 190

51 Law of One Price Definition The law of one price: Two goods, if they are identical, must sell for the same price. Domestic Economy The law of one price in the context of domestic economy the relationship holds if transaction costs are allowed: e.g., P I = P A + C where P I, P A is the price of the same good in Istanbul and Ankara respectively and C is the transaction cost (transportation, local taxes, etc.). The idea here is that arbitrage opportunities will be eliminated by trade.

52 PPP and Real Exchange Rate Definition The PPP relation is given by P i = SPi for i = 1,..., N where P i is the domestic price of good i and Pi is the foreign price of good i and S is the exchange rate or P = SP where P is domestic price index and P is the foreign price index Definition The real exchange rate, Q, between two countries is given by Q = SP P. Corollary If PPP holds then Q = 1. Example: When PPP adjusted India s GDP is 3,608 billion dollars as opposed to 1,704 billion dollars calculated with nominal exchange rates. Denmark GDP per head: PPP adjusted: $37,500 vs. Nominal Exch Rate: $62,100 Ozan Hatipoglu (Department of Economics) Open Economy Macroeconomics Spring / 190

53 PPP and Inflation Theorem If PPP holds then the rate of home currency depreciation rate is equal to difference between home and foreign inflation rates. Proof. Taking logarithms and derivatives of both sides of P = SP log(p) = log(s) + log(p ) dp/p = ds/s + dp /P ds/s = dp/p dp }{{}}{{} /P }{{} depreciation = inflation inflation In reality PPP fails most of the time.

54 PPP and Transaction Costs Let K be a constant that represents the total costs of conducting international trade including tariffs, etc. P = KSP log(p) = log(k ) + log(s) + log(p ) Theorem If trade costs are constant, then they do not affect the currency depreciation rate Proof. Taking the derivative above yields ds/s }{{} = dp/p }{{} dp /P }{{} dk /K }{{} depreciation = inflation inflation change in trade costs but dk = 0 Ozan Hatipoglu (Department of Economics) Open Economy Macroeconomics Spring / 190
