  1. The International Monetary System READING ASSIGNMENT: Oatley – Chapter 10

  2. Plan for today • Testing the argument & How to read statistical results -- a cheat sheet • Exchange Rate Systems • Balance of Payments • Adjusting the BoP under fixed exchange rates • Adjusting the BoP under floating exchange rates • The rise and fall of Bretton Woods

  3. The argument from last class in a nutshell: • Remittances  Fixed Exchange Rates • Why? • Fixed XR reduce uncertainty for international transactions and should therefore increase such transactions • The problem with Fixed XR is that governments lose monetary autonomy to deal with cyclic problems of unemployment and inflation • But remittances flow counter-cyclically • win-win!

  4. Test the argument! • Statistical approach allows for: • The analysis of many, many cases • A measure of uncertainty

  5. Check list: • What is the dependent variable (the thing we want to explain – usually in the table’s title)? • What is the unit of analysis (the nature of the observations)? • What are the independent variables of interest? • Main independent variable(s) • Control variables • What are their effects? In a non-linear model, just look for “positive” or “negative” COEFFICIENTS • Is the model linear or non-linear? • How confident are we in each effect? 3 ways to report: (star gazing) • Standard error: 95% significant if < ½ the size of the coefficient… really <1/1.96) • T-stat (or Z-stat): 95% significant if >1.96 • p-value: 95% significant if < 0.05

  6. The International Monetary System

  7. Exchange-Rate Systems • A set of rules governing how much national currencies can appreciate and depreciate in the foreign exchange market • FIXED: governments allow for only very small changes. The government maintains this fixed price by buying & selling currencies in the foreign exchange market (e.g., China) • FLOATING: governments do not intervene. There are no limits on how much the XR can move up or down (e.g., US$) • FIXED-BUT-ADJUSTABLE: Governments intervene under a set of well defined circumstances (e.g., Bretton Woods… note: well defined circumstances can be devastating with speculators – surprise is important when it comes to monetary policy!) • MANAGED FLOAT: Governments intervene but there are no rules (surprise!) – these days most governments do this…

  8. A little foreshadowing to connect XR to Monetary Policy http://www.thedailyshow.com/watch/tue-september-18-2007/alan-greenspan

  9. Balance of Payments • Current Account: records all current (nonfinancial) transactions between the home country and the rest of the world • Imports & exports of goods & services, royalties, fees, interest payments, profits, remittances, foreign aid grants • Capital Account: records financial flows between the home country and the rest of the world • Foreign direct investment, portfolio investment (stocks & bonds), & other investments (such as changes in holdings in loans, bank accounts, and currencies) • Mirror images of each other – current account deficits go with capital account surpluses & vice versa • But with millions of international transactions there is no assurance will produce a perfect balance. When they don’t, the country faces an imbalance of payments

  10. Adjusting the BOP under Fixed XR • The adjustment occurs through PRICE CHANGES • Deficit countries see a reduction in the money supply • So prices fall • Surplus countries see an increase in the money supply • So prices rise • The prices of goods (and services… wages?) actually rise and fall! • The government maintains the fixed XR by using monetary policy • Interest rates go up in deficit countries, they go down in surplus countries • Monetary policy cannot be used to manage domestic economic activity (unless there are strict capital controls)

  11. A note on wages • Under a fixed XR, if a country has a trade deficit, • Whether wages fall partly depends on the strength of labor unions • If unions are strong, they may be able to prevent wages from falling • But in this case, unemployment will likely rise

  12. Adjusting the BOP under Floating XR • The adjustment occurs through EXCHANGE RATE MOVEMENTS • Deficit countries see a depreciation in their currency (excess supply of the currency lowers the “price” or XR of the currency) • So, in terms of other currencies, • Prices of exports fall – Accordingly, demand for exports goes up • Prices of imports rise – Accordingly, demand for imports goes down • Surplus countries see an appreciation in their currency (excess demand for the currency increases the “price” or XR of the currency) • So, in terms of other currencies, • Prices of exports rise – Accordingly, demand for exports goes down • Prices of imports fall – Accordingly, demand for imports goes up • Balance is restored as deficit countries see imports go down & exports go up while surplus countries see imports go up and exports go down • Prices of domestic goods (& services… wages) remain relatively stable • The government is free to pursue domestic policy goals (employment, for example) by using monetary policy • E.g., lower interest rates to stimulate demand… economic growth; raise interest rates to fight inflation

  13. Take-aways • Testing the RemittancesXR story • XRs: (1) Fixed, (2) Adjustable, (3) Managed, (4) Float • Adjusting the BoP under fixed exchange rates • Monetary policy raises/lowers money supply to deal with surplus/deficit • Adjusting the BoP under floating exchange rates • XR appreciates/depreciates to deal with surplus/deficit • Democracies like monetary policy autonomy • The rise and fall of Bretton Woods
