This marvelous plot comes from an interesting article, The Monetary and Fiscal History of Brazil, 1960-2016 by Joao Ayres, Marcio Garcia, Diogo A. Guillén, and Patrick J. Kehoe. The article is part of the Becker-Friedman Institute Project , complete with a big and now easily available data collection effort, and forthcoming book .  If you want a deep historical and economic analysis of fiscal and monetary interactions, this is an amazing resource. And it summarizes historical episodes that North Americans just might want to know more about soon!  (HT Ricardo Reis who pointed it out in a great discussion last week, that I will post as soon as it's available.)  To me the graph is at first blush a reminder that inflation can stop on a dime, despite sticky prices, seemingly adaptive or sticky expectations, Phillips curves, and so forth. Brazil seems to have had 6 Tom Sargent "end of inflations" episodes in 10 years! (Reminder: Tom showed that inflation can end very quickly i...

I just got the program for the upcoming NBER summer institute monetary economics conference program .  Who says academics aren't up to the minute on policy issues? This will be interesting.   

 I gave an Economic policy working group talk at Hoover on Wednesday, on a little essay " r<g " with some earlier thoughts from " low interest rates and government debt " If the above embed doesn't work, it's on the Hoover webpage here . Does an interest rate lower than the growth rate of the economy mean that debt is a free lunch, or at least a really cheap snack? I don't think so. Major points: the r<g scenarios of one-time borrowing or financing a small deficit are irrelevant for the US actual fiscal issues of perpetual huge deficits and exploding debt. I also grapple with the economics. An economy can have a well defined debt equals present value of surpluses, in which deficits must be repaid, yet show E(r)<E(g). The usual finite horizon discount factor tricks can blow up. Toward the end Markus Brunnermeier catches a subtlety important to my characterization of his work, which I will fix in the next draft, though the existing points seem to ...

I got a chance to see the page proofs of Michael Weisbach's upcoming book, " The Economists' Craft. "  This leapt out at me from the preface:  A second observation I have made over the years is that, perhaps because of a lack of good advice, many scholars, both doctoral students and faculty members, constantly make the same mistakes. Far too many publicly circulated papers contain incredibly long, mind-numbingly dull literature surveys; introductions that go on and on before they tell the reader what the point of the paper is and why the reader should bother to waste her time on it; data descriptions containing insufficient detail for a third party to replicate the results; tables that are unnecessary, badly labeled, or hard to understand; or overly dry prose written in the passive voice and apparently designed to put the reader to sleep. In addition, many scholars manage their time so badly when giving presentations that they do not get to the main results of their p...

  Source. My correspondent provides the answer:  5bps: IVV (column #3) (iShares Core S&P 500 ETF) 15bps: ESGU (column #1)  (iShares ESG Aware MSCI USA ETF)  30bps: LCTU (column #2) (BlackRock U.S. Carbon Transition Readiness ETF) “Sea change” quote from BlackRock here   I have not independently checked, though the answer hardly matters. The fees and portfolios tell the story. Obviously any claim that this ESG portfolio will outperform after fees is ... strained.  When I did my Senate testimony on financial regulation and climate change, someone (I forget who)  suggested that financial regulators need to really crack down on ESG, carbon, diversity, and other virtue claims by investment managers and large corporations. I heartily agree. Of course, we have different motivations.  I got the sense that the person suggesting it wanted to make sure companies really did keep all their virtuous promises. I think that being forced to document thei...
