About me and this page
Welcome to my web page. Here you can find just about anything I've ever written.
The Contact information page has all the ways to contact me, media contact information, and few more pictures in different sizes.
The Research link will take you to all my academic writing, including published books, papers, working papers and comments. It includes comments and talks given at academic conferences. It also has information about my textbook, Asset Pricing
The News, Op-eds link takes you includes op-eds, blog posts, links to media coverage, slides and videos of talks, and other items of interest to the average non-academic.
I usually post slides of any talk I've given, so if there was some delicious graph you saw at a talk, you're likely to find it in the Research (for academic talks) or News (for other talks) links.
In December 2011 I started a blog with news and opeds and commentary.
Teaching takes you to class web pages. Students: these are the right web pages. Booth sometimes echoes old and out-of-date information to other sites. Visitors: you are welcome to use any of my materials that you find useful, so long as you cite their source. All: yes, the problem set answer links don't lead anywhere when I'm not teaching.
Data and Programs takes you to a webpage with data and programs for older papers. Starting 2011, I'm posting links to data and programs next to the paper on these pages, but I haven't yet cleaned up the old papers to that method.
If you're a sailplane pilot looking for Soaring writing, go to the soaring link. If you're an economist but flying gliders sounds a lot more interesting than whatever else brought you here, go ahead and take a look.
I'm a proud father and husband of a creative family. Check out the Family web page, with art, comics, animation, music, plus the famous Hippo pages. Warning: If you click this link you may not be back for an hour or two. My wife, Elizabeth Fama is a young adult book author, elizabethfama.com is her web page and blog, her latest books are Monstrous Beauty and Plus One. My daugher Sally's paintings and blog are worth a detour.
This is (July 2011) a big web site redesign. Please let me know about inevitable bugs, broken links, etc.
Academic articles and working papers
- Michelson-Morley, Fisher, and Occam: The Radical Implications of Stable Inflation at the Zero Bound Revision, May 2017. The fact that inflation is quiet and stable at zero rates cleanly invalidates the standard old-Keynesian model, which predicts a deflation spiral, and almost as cleanly invalidates new-Keynesian sunspots. New Keynesian price stickiness plus fiscal theory selection works well. Stable inflation suggests a higher rate will raise inflation. That conclusion is hard to escape, even temporarily. One fiscal theory mechanism with long term debt does it. Even that does not rescue traditional views of monetary policy. A shortish nontechnical summary. Data and Programs. Conference draft. (Dec 2016) This paper combines the talk by that title with a much revised "Do Higher Interest Rates Raise or Lower Inflation," which no longer exists as a separate paper.
- Do Higher Interest Rates Raise or Lower Inflation? 2016 This paper is superseded by Michelson-Morley, Fisher, and Occam: The Radical Implications of Stable Inflation at the Zero Bound, longer entry above.
- Stepping on a Rake: the Fiscal Theory of Monetary Policy" Revised, July 2017. (First draft August 2016; was "Stepping on a Rake: Replication and Diagnosis"). The fiscal theory of the price level can describe monetary policy: interest rate targets, quantitative easing, and forward guidance. With long term debt, a higher interest rate can produce temporarily lower inflation. The paper starts with a completely frictionless environment, and then replicates Chris Sims's "stepping on a rake" paper, which has the latter result along with elaborations that smooth out the impulse-response functions. I boil Sims down to the central ingredient,long term debt. The replication is useful if you want to know how Sims derived his model or solved it; also useful as a guide to solving continuous-time sticky-price models with jumps. matlab program archive
- The New-Keynesian Liquidity Trap Revised again again again August 2017. matlab program. In standard solutions, new-Keynesian models produce a deep recession with deflation at the zero bound. Useless government spending, technical regress, and capital destruction have large positive multipliers. The recession, deflation and policy paradoxes are larger when prices are less sticky, and news has larger effects for events further in the future. These features are all artifacts of equilibrium selection. For the same interest-rate policy, equilibria that limit a downward jump of inflation on news of the trap, for the same interest rate policy, reverse all these predictions. They predict mild inflation, little output variation, and negative multipliers during the liquidity trap. Their predictions approach the frictionless model smoothly, and promises in the far-off future have less effect today. A big deflation means people expect the government to raise taxes or cut spending a lot to pay off a windfall to bondholders. Thus, fiscal considerations suggest the equilibria with limited jumps and effects.
- Macro-Finance 2017. Review of Finance 21(3): 945-985. Links: Publisher (doi) , Last manuscript. This is a review paper. I survey many current frameworks including habits, long run risks, idiosyncratic risks, heterogenous preferences, rare disasters, probability mistakes, and debt or institutional finance. I stress how all these approaches produce quite similar results and mechanisms: the market's ability to bear risk varies over time, with business cycles. I speculate with some simple models that time-varying risk premiums can produce a theory of risk-averse recessions, produced by varying risk aversion and precautionary saving, rather than Keynesian flow constraints or new-Keynesian intertemporal substitution. The July 2016 manuscript contains a long section with thoughts on how to make a macro model based on time varying risk premiums, that got cut from the above final version. (This is the "manuscript" referenced in the paper.) The Data and programs (zip, matlab). The slides for the talk. A very nice post on the Review of Finance Blog summarizing the paper, by Alex Edmans, the editor.
- The Fragile Benefits of Endowment Destruction. November 2015. Journal of Political Economy 123(5) 1214-1226. With John Y. Campbell. (JSTOR / JPE Link.) A rejoinder to Ljungqvist and Uhlig "Comment on the Campbell-Cochrane Habit Model" (formerly titled "Optimal Endowment Destruction under Campbell-Cochrane Habit Formation"). The benefits of endowment destruction depend sensitively on how you discretize the model. Lesson: It's better to use the the continuous time version and make sure discretizations make sense. There is a nice lesson on how to extend diffusion models to jumps too. Computer program.
- A response to Sims (2013) January 2015. Chris Sims' (2013) "Paper Money" seems to include a criticism of my "Determinacy and Identification with Taylor Rules". In fact, there is essentially no fundamental disagreement between the two papers.
- A New Structure for U.S. Federal Debt November 2015 In David Wessel, Ed., The $13 Trillion Question: Managing the U.S. Government's Debt, pp. 91-146. Washington DC: Brookings Institution Press. Last manuscript. I propose a restructuring of U. S. Federal debt. All debt should be perpetual, paying coupons forever with no principal payment. The debt should be composed of 1) Fixed-value, floating-rate, electronically transferable debt. Such debt looks like a money-market fund, or reserves at the Fed, to an investor. 2) Nominal perpetuities: This debt pays a coupon of $1 per bond, forever. 3) Indexed perpetuities: This debt pays a coupon of $1 times the current consumer price index (CPI). 4) All debt should be free of income, estate, capital gains, and other taxes. 5) long term debt should have explicitly variable coupons. 6) Swaps. The Treasury should adjust maturity structure, interest rate and inflation exposure of the Federal budget by transacting in simple swaps among these securities.
- Monetary Policy with Interest on Reserves Journal of Economic Dynamics & Control 49 (2014), 74–108 ( ScienceDirect link to published version, html and pdf) I analyze monetary policy with interest on reserves and a large balance sheet. I argue for the desirability of this regime on financial stability grounds. I show that conventional theories do not determine inflation in this regime, so I base the analysis on the fiscal theory of the price level. I find that monetary policy -- buying and selling government debt with no effect on surpluses -- can peg the nominal rate, and determine expected inflation. With sticky prices, monetary policy can also affect real interest rates and output, though not with the usual signs in this model. Figures 2 and 3 are the best part -- the effects of monetary policy with and without fiscal coordination. I address theoretical controversies, and how the fiscal backing of monetary policy was important for the 1980s disinflation. A concluding section reviews the role of central banks. Matlab program.
- Toward a run-free financial system. November 4 2014. In Martin Neil Baily, John B. Taylor, eds., Across the Great Divide: New Perspectives on the Financial Crisis, Hoover Press. This is an essay about what I think we should do in place of current financial regulation. We had a run, so get rid of run-prone liabilities. Technology and financial innovation means we can overcome the standard objections to "narrow banking." Some fun ideas include a tax on debt rather than capital ratios, the Fed and Treasury should issue reserves to everyone and take over short-term debt markets just as they took over the banknote market in the 19th century, and downstream fallible vechicles can tranche up bank equity.
- Challenges for Cost-Benefit Analysis of Financial Regulation. Journal of Legal Studies 43 S63-S105 (November 2014). Is cost benefit analysis a good idea for financial regulation? I survey the nature of costs and benefits of financial regulation and conclude that the legal process of current health, safety and environmental regulation can't be simply extended to financial regulation. I opine about how a successful cost-benefit process might work. My costs and benefits expanded to a rather critical survey of current financial regulation. It's based on a presentation I gave at a conference on this topic at the University of Chicago law school Fall 2013, with many interesting papers. JSTOR link with HTML and nicer pdf. The JLS issue with all conference papers.
- A mean-variance benchmark for intertemporal portfolio theory Journal of Finance, 69: 1–49. doi: 10.1111/jofi.12099 (February 2014) (link to JF) (Manuscript) Applies good old fashioned mean-variance portfolio analysis to the entire stream of dividends rather than to one-period returns. Long-Run Mean-Variance Analysis in a Diffusion Environment is a set of notes, detailing all the trouble you get in to if you try to apply long-run ideas to the standard iid lognormal environment, and also discusses shifting bliss points a bit.

- After the ACA: Freeing the market for health care Sept 2015 In The Future of Healthcare Reform in the United States Edited by Anup Malani and Michael H. Schill, p 161-201, University of Chicago Press. An essay on health care, first presented at the conference, The Future of Health Care Reform in the United States, at the University of Chicago Law School. Most of the policy discussion is focused on health insurance. But the health care market is dysfuctional, and needs to be fixed as well. Where are the Southwest Airlines, Walmart and Apple of health care, bringing cost saving, efficiency, and innovation? I argue that we need a big freeing up of health care markets. I also focus more than usual on supply restrictions. It doesn't do much good for people to pay with their own money if suppliers cannot respond to that demand.

Academic Talks and Comments
- Inflating away our troubles? April 22 2017 Comments on "Inflating away the public debt? An empirical assessment" by Jens Hilscher, Alon Aviv and Ricardo Reis. A little inflation will not likely help our debt problems. An interest rate rise could make matters much worse, and precipitate a debt crisis, which would cause a lot of inflation. Slides
- Comments on "A Behavioral New-Keynesian Model" by Xavier Gabaix. Comments presented at the October 21 2016 NBER EFG meeting. The model is really important. It is an alternative to active Taylor rules in NK models, solving zero bound and other problems. But it puts a lot of irrationality deeply at the heart of monetary economics. Slides
- Volume and information. Comments on "Random Risk Aversion and Liquidity: a Model of Asset Pricing and Trade Volumes" by Fernando Alvarez and Andy Atkeson. Comments presented at the Conference in Honor of Robert E. Lucas Jr., Becker-Friedman Institute, October 7 2016. Andy and Fernando have a nice paper, which I pretty much ignored and summarized some thoughts on the big puzzle of volume instead.
- Michelson-Morley, Occam and Fisher: The radical implications of stable inflation at the zero bound Slides for talk at the European Financial Association, August 2016. This became the paper listed above. It's an evolution of the similar slides for my talk given at the Columbia-New York Fed conference honoring Michael Woodford May 18-19 2016. The ZLB is a deeply revealing moment for monetary economics, like Michelson-Morley's famous experiment. Nothing happened. Many theories say big things should have happened, and those theories are wrong. (Well, unless you add epicycles, ether drag, or other ugly complications. Hence Occam's razor.) In the new version I incorporate Sims' insight for how to get a temporary negative inflation out of a rate rise. In the same vein slides for a 1.5 hour MBA class covering all of monetary economics from Friedman, Sargent-Wallace, Taylor, Woodford, and FTPL.
- Comments on 'the Fundamental Structure of the International Monetary System' by Pierre-Olivier Gourinchas. April 2017. In Rules for International Monetary Stability edited by Michael D. Bordo and John B. Taylor, p. 186-195, Stanford: Hoover Institution Press. (The link includes the final paper and my comment.) The comments, presented at the conference, "International Monetary Stability: Past, Present and Future," Hoover Institution, May 5 2016, refer also to the original paper 'Global Imbalances and Currency Wars at the ZLB,' by Ricardo J. Caballero, Emmanuel Farhi, and Pierre-Olivier Gourinchas. The papers model "Global imbalances," "savings gluts," "safe asset shortages," and so forth, with a dramatic "tipping point" at the zero bound. At the bound "inability to produce safe assets" in one country spills over to output gaps at another one. I outline a different world view and contrast the two worlds.
- Comments on "How Can Central Banks Deliver Credible Commitment and be 'Emergency Institutions'" By Paul Tucker. In John H. Cochrane and John B. Taylor, Eds., Central Bank Governance and Oversight Reform, Hoover Institution Press May 2016, p. 31-36. (Chapter pdfs available here) Comments presented at the Hoover conference by the same name, May 21, 2015. Tucker's paper here. Tucker wisely advocates rules for mop ups, lender of last resort, bailouts, etc. I agree, but wouldn't lots more equity so you don't have to mop up be simpler?
- The fiscal theory of the price level and monetary policy: An agenda April 1, 2016. Slides for a talk at the Next Steps for the Fiscal Theory of the Price Level conference at the Becker-Friedman Institute, April 1 2016. The Fiscal Theory is that the real value of nominal debt equals the present value of primary surpluses. The agenda is making this fact come alive in the analysis of history, of data, of policy, and of better monetary and fiscal regimes. To that end, I argue we've paid to much attention to surpluses, and not enough to discount rates or to debt and monetary policy. I show how we need discount rates to understand the cyclical variation of inflation, and how monetary policy is quite strong in the fiscal theory, by the ability to control nominal interest rates and thus expected inflation.
- Comments on Bauer and Hamilton. Nov 5 2015. Comments on Robust Bond Risk Premia by Michael Bauer and Jim Hamilton, at the 5th Conference on Fixed Income Markets, San Francisco Federal Reserve, Nov 5 2015. I look at the evidence whether macro variables help to forecast bond returns. It turns out a trend does even better, pushing the R2 up to 62 percent! That finding suggests that specification issues rather than distribution theory are the central problems. I don't find that the Bauer-Hamilton effect size distortion is big. I document measurement errors in the data, which are a good target for econometric help. I opine we need to spend less attention on one asset at at time forecasting and more attention on the factor structure of expected returns across assets, and how that structure lines up with covariances of returns with shocks. There is also a little example of perfect non-spanning in a term structure model; bond yields have an exact one factor model, but a non-spanned factor drives expected returns. Programs and data (zip)
