15 days ago

The world is going through a remarkable transformation in the aftermath of an unprecedented shut down of economies all over the globe.

Contagion

March 5, 2020

Central banks throughout the world are charged not only with price stability, but also with maintaining financial stability. For example, the Federal Reserve is charged with maintaining maximum employment and stable prices and the Bank of England now has an entire new building packed with financial regulators.  Historically, the Fed has achieved its employment mandate by …

Taxing Billionaires

November 23, 2019

I just read a fascinating twitter exchange between @Noahpinion and @gabriel_zucman. My scoring so far: Noah: 10: Gabriel: 0 Gabriel argues for taxing billionaires immediately based on the principle of “ability to pay”. Noah asks if his reasoning is based on some unarticulated moral principle; or is it on practical grounds. The State needs the …

Central Bank Equity Purchases: An Idea Whose Time has Come

August 2, 2019

Writing in the Financial Times last week, BlackRock executive, Rick Rieder, urged the ECB to purchase equities in an attempt to stimulate growth in the Eurozone. Merryn Somerset Webb, disagrees. While Merryn is correct to point out that BlackRock stands to benefit from a policy that would increase equity prices in the Eurozone, that is not a …

There are many unemployment rates for any r*

March 3, 2019

Eric Lonergan has a new blog post in which he draws attention to the importance of the asset markets in business cycle dynamics. While there is much to like in that post, I find parts of Eric’s argument misleading. Here is Eric: “This leads us to the how [stet] the equity market determines the ‘neutral …

Social Progress is not an Illusion

January 12, 2019

I recently came across this critical review of Steven Pinker’s book, Enlightenment Now: The Case for Reason, Science, Humanism, and Progress, by Jeremy Lent in the online magazine, Open Democracy. Jeremy makes some good points, but then proceeds dramatically to overstate his case by painting a monothlithic concept of ‘free market economics’ as the enemy of …

Don’t Trust the Markets

December 26, 2018

In a week when the Vix is at a seven-year high and the markets are back to the trading range of the summer of 2017, now seems like a good time to revisit the theme of market efficiency. Here is a link to the pre-publication version of an academic paper I published this year in …

Taxing the Intangible Economy

July 11, 2018

With a slowdown in productivity growth hurting Western governments’ ability to deliver goods and services, new forms of revenue generation are needed. One possible solution is to tax capital gains at the same rate as other income.

LONDON – Some very clever people, including the president of the European Central Bank, Mario Draghi, and Andy Haldane, chief economist at the Bank of England, are expressing concerns over the slowdown in productivity growth. And, given that productivity (measured as GDP per hour worked) is the ultimate driver of increases in living standards, they are right to be worried. For most people in the West, wages and living standards have stagnated for decades. If you were a factory worker in the north

Taming the Lion

June 3, 2018

In the nineteenth and early twentieth centuries the business cycle was a wild ride. Part of the damage inflicted by financial crises was caused by price instability. That problem was successfully solved in the 1980s when the Fed adopted inflation targeting. The success proved chimeric.  My last post argued for a second policy, designed to …

Bulls and Bears: Why central banks should stabilize the stock market

May 30, 2018

My paper, Pricing Assets in a Perpetual Youth Model was recently published in the Review of Economic Dynamics. The paper uses mathematics to make a point.  But the idea is simple and worth explaining in English.   The paper constructs a formal mathematical model to capture the idea that free trade in capital markets does …

Moving the Overton Window: Let the Debate Continue

April 19, 2018

The NIESR Rebuilding Macroeconomics project is stirring a great deal of controversy. And that’s a good thing. I am part of the management team. But I can only speak for myself here. In my opinion,  we should be generating dialogue between heterodox non-mainstream groups and conventional macroeconomists. Mainstream economists, and heterodox economists alike, should each stop being …

Standing on the Shoulders of Giants

April 14, 2018

I have rarely read anything as unhelpful to the task of Rebuilding Macroeconomics as Howard Reed’s poisonous attack on the foundations of the dismal science. I have a lot of sympathy for Howard’s position. But if you are young and committed, with a desire to rebuild economics, your first job is to understand the edifice you …

What Does it Mean to Have Rational Expectations?

March 18, 2018

This is a follow up to my ergodicity post from last week. Both posts are inspired by conversations I had with my Co-Hub-Leader Jean Philippe Bouchaud (for the Rebuilding Macroeconomics Hub: Why are Economies Unstable?) on the role of the ergodicity assumption in science. Content warning: This is more technical than many of my posts with no apologies. It …

My new working paper, joint with Pawel Zabczyk, is out now as an NBER working paper, a CEPR discussion paper and a NIESR discussion paper. Here is the abstract:  We refer to the idea that government must ‘tighten its belt’ as a necessary policy response to higher indebtedness as the household fallacy. We provide a reason …

Ergodicity

March 12, 2018

Last Thursday, Jean-Philippe Bouchaud and I held the first meeting of the Rebuilding Macroeconomics project’s Instability Hub. There were roughly twenty people, some in attendance in person and some attending through Zoom. As expected, what emerged was an eclectic mix of ideas, some better presented or better formed than others. The overarching theme that emerged …

Confidence and Crashes

February 7, 2018

The Dow dropped 4.6% on Monday February 5th.  This was the biggest recorded point drop, 1,175, in history. The markets regained some ground on Tuesday and, as of writing this post, we have simply wiped out the gains that have accumulated since the beginning of January. But we are not yet out of the woods. …

What We Know for Sure that Just Ain’t So

January 31, 2018

“What gets us into trouble is not what we don’t know. It’s what we know for sure that just ain’t so.” Mark TwainDavid Smith has a piece in the Times yesterday that, as always, is worth reading. But David is a little too certain for my taste. I prefer to follow the dictum that prediction …

Freedom of the Press and Internet Filters

January 28, 2018

Here are a few thoughts that were inspired by Richard Baldwin’s tweet, Random Sunday Findings… “Freedom of the Press is guaranteed only to those who own one”. A.J. Liebling. It was naïve to think that the internet would change the balance in favor of a more balanced flow of ideas when social media filters the content …
