INTERNATIONAL ECONOMICS—FINAL EXAM

(3-4 pm, July 23, 2004)

Instructor: Professor Kenichi Ohno

 

l         This is a closed book exam. Use your pen and brain only.

l         PLEASE WRITE CLEARLY. Poor handwriting will be ignored, resulting in lost points.

l         ANSWER ALL QUESTIONS. Use only TWO official answer sheets. Use only FRONT side of each answer sheet. Allocate space carefully.

l         Clear and concise answers are preferred. Long answers do not guarantee high points.

l         After the exam, model answers will be distributed. Graded answer sheets will be returned to the students a few days later and overall results will be posted in the web.

 

 

Answer in any order; each question carries 20 points

 

Q1. Describe the price-species flow mechanism. Is it a valid model of the classical gold standard (1879-1914)?

 

Q2. What caused the first oil shock (1973-74)? Present two alternative views.

 

Q3. Explain the first generation models and the second generation models of currency crisis.

 

Q4. Evaluate the IMFfs policy advice at the time of the Asian financial crisis (1997-98).

 

Q5. The US demanded the appreciation of the Japanese yen in the past, and the US now asks China to appreciate the RMB. Explain the mechanism behind this US pressure.


Model answers

(Other answers are often possible)

 

Q1. The PSF mechanism is a model of automatic balance-of-payments adjustment through gold flows and price change. If the current account (CA) is in deficit, gold flows out of the country, causing monetary contraction and price deflation. This improves competitiveness and CA. The reverse occurs when CA is in surplus. However, the PSF mechanism ignores capital mobility. Under the classical gold standard with integrated goods and financial markets, external adjustment was quickly achieved via private capital flows, without a forced slow change in money or price levels across countries.

 

Q2. The supply shock view argues that global stagflation was caused by the OPECfs aggressive oil price increase, shifting the aggregate supply curve upward which raised prices and reduced output. This was combined with wage rigidity, which increased unemployment further. Floating exchange rates were beneficial as a shock absorber. By contrast, the global monetarist view says that the OPEC action was the result, not the cause, of worldwide excess liquidity, which in turn was caused by currency interventions of major countries at the time of the collapse of the Bretton Woods fixed exchange rate system. According to this view, the lack of an effective global nominal anchor was the cause of both general floating and commodity inflation in the early 1970s.

 

Q3. The first generation models state that a policy inconsistent with a fixed exchange rate (continued budget deficit and monetary expansion) inevitably leads to a currency crisis. The exact timing of the attack depends on the shadow exchange rate, a hypothetical exchange rate which would prevail after the attack. The second generation models argue that attacks are possible even without any apparent policy failure. Policy nonlinearity leads to multiple equilibria where both attack and non-attack solutions are possible. Crisis dynamics is driven by private traders who exhibit such irrationalities as herding, self-fulfilling attacks, information cascade, sunspot equilibria, etc.

 

Q4. Ex ante, IMF often encouraged LDCs to open up financial sectors prematurely. Ex post, IMF applied current account policies to the capital account crisis--a mismatch between the disease and the cure. In particular, the following IMF conditionalities are now considered inappropriate: (i) macroeconomic austerity at the time of collapsing private demand; (ii) high interest rates to stop the currency fall; and (iii) structural reform measures adopted in the middle of crisis, including bank closures in Indonesia. Some argue that the Asian crisis worsened unnecessarily due to these measures. In 2003, IMF issued an evaluation report which largely admits to such criticisms.

 

Q5. The US Congress and industrial lobbies criticize major trading partners whenever the US trade deficit rises above a certain limit. A country with a large trade surplus with the US is targeted, with the demand for currency appreciation and trade concessions (including institutional reform for gfairh access). While these measures are largely ineffective since the US deficit is homemade (i.e., due to the lack of domestic saving), pressure continues as long as trade remains a politically sensitive issue. Around 2000, China replaced Japan as the largest surplus country with the US. As a result, US pressure is now mainly directed to China, which faces the problem of smooth transition from fixed RMB to a floating one without inviting a crisis (the exit policy problem).
