April 2, 1998; revised September 10, 1998
Dear XXXX,
First, let me apologize for getting this to you at the end of this week, rather than at the beginning: Labor Day weekend turned out to be much less productive a time for thinking than I had believed it would be. So this is getting to you on Thursday morning rather than Tuesday morning. I hope there is still enough time for you to turn this over in your mind before lunch tomorrow.
My thinking about writing a macroeconomics textbook over the summer has led me to the following three conclusions: (I) I could do a better job than is currently done in Mankiw or in Abel and Bernanke or in Dornbusch, Fischer, and Startz. (II) It would be intellectually challenging. And (III) it is something that I do want to do--I have discovered that doing these CD-ROM projects for Cogito has not alleviated but has instead irritated the itch, and I would have a very hard time keeping from scratching it.
There are, however, big uncertainties: (I) How much support--both in writing the book and then in marketing it--would XXXX provide? (II) How much fun would writing a textbook be? (III) How much money would I make? (IV) When would XXXX expect the manuscript, for as I said before it is unlikely that I would be able to deliver chapters in appreciable numbers before late next spring, and unlikely that I would be able to deliver an entire manuscript before some time late next summer.
With my uncertainties out on the table, let me try to reduce your uncertainties by sketching out what I think that I would do in a macroeconomics textbook.
First, I would keep in mind Tim Taylor's principle that no textbook that wishes to sell in any volume whatsoever dares deviate more than 15% from the previous models--in this case Mankiw and Abel and Bernanke. People who have taught from the old dominant textbooks have to be able to easily teach (or at least to think in advance that they will be able to easily teach) from the new. The new has to be different enough and better enough to be exciting, but also largely the same.
Second, I believe that Greg Mankiw did not go far enough (possibly because he was constrained by the 15% rule) in shifting the balance of macroeconomics away from short-term fluctuations in unemployment and toward long-run issues. So I would place more stress on long-run growth--try to do a more serious job (and spend more of the semester) on long-run growth than in today's textbooks.
After an introductory chapter, a chapter on how the modes of thought common to economists are different from those found in everyday life, and a chapter on the way that we find out about and organize our data on the macroeconomy, I would go straight into long-term growth, looking first at economists' theories of growth, and then at the patterns of long-term growth that we see in the world.
I would significantly reorient the presentation of the theory. The pattern that has become standard since Mankiw is essentially to take the graduate student-level presentation of Robert Solow's growth model and to present it to the undergraduates at a glacial pace, in the hope that the slow pace will keep students from getting lost. This seems to me to be a pedagogical disaster. The key variable in the Solow formulation is k*, the level of the economy's capital stock per "effective worker." Even here at Berkeley, no more than one out of three undergraduate students understands when the final exam comes around what capital per "effective worker" means.
I think a much more understandable and robust version of the same theoretical material could be presented by focusing not on k* but on the capital-output ratio. Ask what needs to be going on in the economy for the capital stock to be a constant multiple of output, and point out that the capital-output ratio tends to converge to its steady state level.
I also believe that economists can do a much better job of presenting the facts about the causes and consequences of long-term economic growth than they do in standard macro textbooks. First there is the fact that our standard measures of GDP per capita--Simon Kuznets's measures--were designed to be underestimates of economic growth. Simon was in the business of constructing underestimates of growth and pointing out that modern economic growth was still, even when underestimated, very rapid. We can do better.
Second, a lot more can be done to make sense of cross-country patterns: the industrial revolution, the spread of industrialization, the twentieth-century lag of Latin America, the East Asian miracle, the African catastrophe, slow growth in India, and the American century can all be taught to undergraduates in a way that will make them sit up and understand why growth went right in some places and wrong in others. I think it is worth spending the time to do this.
After covering long-run growth, I would move into full-employment macroeconomics: the division of potential output between consumption, investment, government spending, and net exports when prices are equal to previously-expected prices, and when national product is equal to potential output. Here I think that the pattern established by Mankiw is very good and hard to improve upon with one exception. The international economy--cross border capital flows, the determinants of net exports, the level of the real exchange rate, and so forth--should be integrated into the standard framework from the very beginning. Even the United States is no longer a closed economy. Even in the United States, every single economic policy issue and news event already has an important international dimension. To try to push international off to selected international chapters is unwise. And it truly is not that difficult to cover international as part of the main narrative thread.
After long-run growth, I would move into first short-run fixed-price aggregate-demand macroeconomics and then into the medium-run topics inflation, unemployment, and output relative to potential. As noted above, I would take the international context much more seriously and integrate imports and exports into the basic multiplier model from the very beginning of the business cycle section. More important, I would simply drop the LM curve. Central banks set interest rates, not money stocks. Dropping the LM curve greatly reduces the algebraic complexity of the determination of aggregate demand, and brings the textbook presentation much closer to what people will find when they open the Wall Street Journal.
I would use the space saved by dropping the LM curve for a serious discussion of the term structure of interest rates. The Federal Reserve controls short-term, nominal, safe interest rates. The principal determinants of aggregate demand are long-term, real, risky interest rates. The slippage between these two is a principal limitation on the government's ability to stabilize the economy. Treating this topic seriously allows us to teach the importance of expectations and the limits of policy in a serious way relatively early in the subject.
The medium-run topics of inflation expectations, inflation, price adjustment, and return to equilibrium would follow fixed-price macroeconomics. I would downplay the aggregate demand-aggregate supply framework: the fact that the price level is central to aggregate supply causes students confusion because the entire discussion of macroeconomic policy is carried out in terms of the inflation rate. Moving from one to the other is not obvious. Thus I would spend much more time on the Phillips curve and the output gap than on aggregate demand and aggregate supply, which I would treat as an alternative framework that carries essentially the same information as the expectational Phillips curve (but that does so in a more convoluted way that is harder to immediately relate to what you read in the newspaper).
Policy chapters (15-19, perhaps), two chapters on the future of the macroeconomy and the future of macroeconomics (20-21 perhaps) and a conclusion would finish off the book.
To summarize, I would:
Take the empirics of economic growth seriously--much
more seriously than is usually done in intermediate
macroeconomics textbooks.Reorient the presentation of economists growth models:
focusing on the steady-state level of the capital stock
per effective worker (as is done in graduate courses) is
a disaster in undergraduate courses. It seems to me that
focusing on the steady-state capital-output ratio in the
presentation of growth theory would be a significant
improvement.Take the international context much more seriously. It should
be integrated it into the basic multiplier model from the
beginning of the business cycle section.Drop the LM curve: central banks set interest rates, not
money supplies. Dropping the LM curve makes the structure
of the argument much clearer and brings the model into
closer correspondence with reality.Take the term structure of interest rates--short vs. long,
real vs. nominal, safe vs. risky--seriously. The fact that
investment and aggregate demand depend mostly on long, real,
risky interest rates while the Federal Reserve can control
only short, nominal, safe interest rates is the source of
much of the uncertainty in economic policy, and is the
principal factor limiting governmental power to stabilize
the economy.
Sincerely yours,
Brad DeLong

- 11-3: The Phillips curve under static expectations
- Changes in inflation don't affect people's expectations
- The short-run Phillips curve does not shift up or down
- Economists see a downward-sloping relationship between inflation and umployment
- 11-4: The Phillips curve under adaptive expectations
- Changes in inflation do affect expectations--with a lag
- The short-run Phillips curve shifts up or down depending on whether unemployment is below or above the natural rate
- Economists see an inverse relationship between unemployment and the change in inflation
- The "accelerationist" Phillips curve
- 11-5: The Phillips curve under rational expectations
- Expected changes in inflation shift the Phillips curve
- Systematic policy has no effect on production or unemployment--only on prices
- Only random, unanticipated shocks have effects on production and unemployment
- Economists see no exploitable relationship between unemployment and inflation
- 11-6: What type of expectations do we have?
- It depends on what kind of economy we live in.
- If inflation is very low and very stable, expectations are probably static
- If inflation is moderate and fluctuates, but slowly, expectations are probably adaptive (adaptive as a good rule of thumb to minimize processing costs)
- If inflation is unstable--and if the stakes to correctly forecasting it are high--expectations are probably adaptive
- Contracting considerations make expectations look less "rational" than they really are...
- Most disagreements between economists involve just how fast the economy moves from one expectations type to another
- 11-7: Stopping moderate inflation
- If expectations are adaptive, then reducing inflation requires a constant "sacrifice"
- The sacrifice ratio
