UCLA. Macroeconomics PhD qualifying examination. Spring 1982

There are basically two kinds of artifacts that make it into the Economics in the Rear-view Mirror collection. There are items that come from (nearly) complete and neatly arranged sub-collections found in university archives and those somewhat random items plucked from the idiosyncratic personal collections of individual scholars. Today’s Ph.D. macroeconomics exam from UCLA is found in a folder of teaching materials for macroeconomics in Robert W. Clower’s papers at Duke University’s Economists’ Papers Archive. 

Other things equal, a balanced panel of such exams across departments and time is what we would ideally hope to accumulate. But the enemy of the good is the perfect in this as in all historical research. So without apology, indeed with a bit of pride, I enter this artifact into our digital record.

Fun Facts: The quote that heads question 9 comes from Charles Dickens’ David Copperfield, for question 10 from Harriet Beecher Stowe’s Uncle Tom’s Cabin.

ECONOMIC THEORY
MACRO PART

TIME: 3 hours — plus an additional 15 minutes for students whose native language is not English.

INSTRUCTIONS: Answer Part I in Bluebook #1 ONLY.

Answer Part II in Bluebook #2 and subsequent books.

DO NOT MIX ANSWERS TO PART I AND PART II IN THE SAME BLUEBOOK.

NOTE WELL: It is extremely important to answer only the questions asked. Extraneous material (whether correct or incorrect) will reduce the score of an otherwise correct answer and no positive credit will be given to correct answers to questions not asked. However, a wrong answer to the question asked will receive a higher score than no answer.

PART I — SHORT ESSAYS
(weight = 1/3)

All questions in this part of the exam are true, false, or uncertain questions. FIRST indicate whether the statement is T, F, or U, and then explain or prove your answer briefly.

Answer only six (6) of the eight (8) questions in this part.

  1. What we should reject is the naive reasoning that there is a demand schedule for investment which could be derived from a classical scheme of producers’ behavior in maximizing profit.
  2. An easy money policy is good for the housing industry in the short run but bad in the long run.
  3. In testing the Quantity Theory of hyperinflations, one must realize that the usual money stock data are apt seriously to underestimate the theoretically relevant money stock. Cigarettes and all sorts of things that become money in hyperinflations are not included.
  4. Although the 1933-1934 increase in the dollar price of gold increased U.S. base money growth, it mainly served at the time as a price-support program for gold.
  5. Relative prices are explained by the theory of value, and, once relative prices are known, money prices are determined by the theory of money.
  6. If the growth rate of nominal money follows a random walk with constant variance, there is no solution to the observational equivalence problem.
  7. The first simple story about inflation is that its underlying cause is deficit spending by the federal government. In that case, the way to fix things up is simply to balance the federal budget.
  8. If expectations are formed rationally and anticipated money does not affect real output, monetary policy cannot stabilize real output.
PART II — DISCUSSION QUESTIONS
(weight = 2/3)

Answer only four (4) of the six (6) questions in this part.

  1. ANNUAL INCOME TWENTY POUNDS, ANNUAL EXPENDITURE TWENTY POUNDS, OUGHT, AND SIX, RESULT MISERY.
    The federal deficit in 1943 and 1944 was nearly $50 Billion, or some 12% of GNP. Long-term bonds yielded no more than 3% per annum in the same years. Do these facts raise any questions in your mind about the validity of present arguments to the effect that projected federal deficits amounting to some 4% of GNP explain present long-term bond yields in excess of 12% per annum? Defend your answer.
  2. NEVER HAD NO FATHER, NOR MOTHER, NOR NOTHIN’. I WAS RAISED BY A SPECULATOR — TOPSY
    1. Explain the analysis behind the presumption, shared by almost all economists, that speculation will be “stabilizing” and not “destabilizing” in any given market that is exposed to regularly recurring “disturbances.”
    2. Explain the role of “speculative behavior” in producing the “instability” problems of Keynesian macrotheory.
    3. “In any system where speculation is based on rational expectations the Keynesian type of income fluctuations should not arise.” Discuss.
  3. IT’S FINE IN THEORY, BUT WILL IT WORK IN PRACTICE?
    From October 1979 to March 1980, money growth slowed sharply in the United States. During the same period of time, inflation accelerated, the unemployment rate rose somewhat, nominal interest rates rose sharply: and the dollar generally appreciated against other major currencies.
    1. Can economic theory account for each of these occurrences? Consider each event separately.
    2. Under what circumstances, if any, are all these events simultaneously consistent with economic theory? Explain carefully.
  1. GOLDEN AND/OR BRASS RULES

In recent years there has been considerable discussion of instituting a monetary “rule” which would make monetary policy non-discretionary. One question, of course, is what form such a monetary “rule” should take. In light of this question, compare and contrast the probable impact on inflation and unemployment in both the short run and the long run from the following two possible monetary rules:

Policy 1: A k-percent rule: legally requiring the growth rate of the money supply to be k-percent.

Policy 2: A modified k-percent rule: legally requiring the growth rate of the money supply to be k-percent only when unemployment is at some target rate \bar{u}. Formally, letting \dot{m} be the growth rate of the money supply, the modified k-percent rule would require that:

\dot{m} =k+\beta \left( u^{a}-\bar{u} \right)

where β is a fixed, positive, non-discretionary constant and u^{a} is the actual unemployment rate.

  1. AN ESSAY ON THE ESSENTIAL ESSENCE
    “IS-LM analysis fails to capture the essence of Keynesian economics because it completely ignores the effect of current levels of output and employment upon current production and consumption plans.”

    1. Is this a fair comment on IS-LM analysis? Explain.
    2. Is its characterization of “the essence of Keynesian economics” valid? Explain why or why not.
  2. SOMETIMES YOU CAN’T LOSE FOR WINNING.
    “Inflation is either unanticipated or anticipated. If unanticipated, it will increase output and employment. If anticipated, it has no effect on output and employment. So either it helps you or it does not hurt you.”

UCLA. Monetary Economics, PhD qualifying exam. 1971

Having just spent nearly a month travelling along the East Coast of the U.S., it is great to get back to posting new content. On this trip I was able to get in three fine days of work in the Economists’ Papers Archive at Duke. While there I found much useful material for Economics in the Rear-view Mirror in the Robert W. Clower papers. A copy of his UCLA obituary can still be found at the Wayback Machine internet archive.

In 1971 Clower joined the UCLA economics department so it is unclear whether he actually contributed to the Ph.D. preliminary examination in monetary economics transcribed below

Monetary Economics

Answer five of the following seven questions.

  1. [On the concept of money]
    1. “Contemporary monetary theory analytically treats money as merely another commodity.” State if (and why) you agree or disagree with this proposition.
    2. Money is sometimes distinguished from commodities by the following assertions. Briefly discuss the meaning of each assertion and whether you agree or disagree with it.
      1. Money has no “intrinsic value”; it cannot be enjoyed directly, but must first be converted into something else.
      2. Money is used but is not used up.
      3. Money buys goods and goods do not buy money.
      4. Money has superior liquidity than other goods.
      5. The value of money is fixed in terms of the unit of account.
      6. Money is traded directly for every commodity and vice versa, while commodities are not traded for one another.
    3. Discuss the limitations placed on research in monetary theory if money is considered merely as a commodity.
  2. Many writers have asserted in the press that the recent international currency “crisis” points up the unique role of the dollar in present international monetary arrangements. Discuss the international role of the dollar with reference to each of the following statements taken discussions of the crisis.
    1. Over the past couple of years the U.S. has been exporting an unwanted inflation to the countries of Europe, especially Germany.
    2. The immediate cause of the crisis was the presence of interest rates in the U.S. which were too low relative to those in Europe and therefore initiated massive capital flows from the U.S. to Europe.
    3. The massive accumulation by foreigners of dollars underlined the fact that the dollar has become de facto inconvertible into gold and was now little more than an unbacked IOU.
    4. The U.S. should be unconcerned with its balance of payments deficit. Under present arrangements any adjustments to international disequilibrium must be made by foreigners; and all the options available to foreign surplus countries, assuming moderately rational behavior on their part, should be acceptable to the U.S.
    5. The recent crisis points up the inherent instability of current international monetary arrangements. The increase in foreign short-term claims upon U.S. gold reserves and the revaluation of currencies in terms of the dollar will undermine the employment of the dollar as the banking currency of the world and speed the development of a unified European currency.
    6. The recent crisis has strengthened the world monetary system by bringing closer the day when the dollar-gold fixed exchange rate standard is replaced by a system of floating exchange rates.
  3. Discuss the following three propositions. (State whether they are true or false and explain why) .
    1. Legal reserve requirements are unnecessary to place a finite limit on the quantity of commercial bank deposits if the deposits are convertible into the government supplied dominant money.
    2. Elimination of the convertibility requirement would lead to an unlimited expansion of deposits.
    3. There is no limit on the extent to which the government can expand the supply of dominant money.
  4. An economist recently wrote a letter to the Wall Street Journal complaining that much discussion of how to control inflation has been based on a neo-quantity theory which emphasizes “the quantity of money” while ignoring “the quality of credit”. The Federal Reserve was established, he noted, to regulate commercial bank assets while current discussion (and policy) concentrates on the liability side of the commercial bank balance sheet and entirely ignores the asset side. He maintained that if, for example, commercial banks were forced to limit their lending activity to short-term, self-liquidating business loans, inflation would quickly be controlled. Evaluate this argument.
  5. [Monetary vs. fiscal policy.]
    1. It is sometimes argued that fiscal policy should be used to maintain domestic full employment while monetary policy should be used to maintain balance of payments equilibrium. Present this argument and clearly state the assumptions upon which it is based.
    2. Summarize and evaluate the existing empirical evidence on the effectiveness of monetary versus fiscal policy as a stabilization device
  6. [Inflation]
    1. Inflation is often considered to be a tax. In what sense is this correct? What is the magnitude of the tax? Who pays and who collects the tax?
    2. What are the effects of inflation on real resource allocation.
      [In (a) and (b) make sure you distinguish between anticipated and unanticipated inflation.]
  7. [The Gibson Paradox]
    1. What is the Gibson Paradox?
    2. Why is it considered to be a paradox?
    3. What theoretical explanations have been advanced to explain the phenomenon?
    4. What is the existing state of the evidence concerning these explanations?
