I am still not entirely sure whether Noah Smith, a U.S. Economist and prolific blogger, is a converted MMTer or not. But I do know that he is doing a great job in describing the discourse around this newfound holy grail of macroeconomic policymaking. In my attempt to label MMT as “Woke Economics”, I leaned on some of Noah’s earlier pieces on this, and now he is back with his invocation of the new Macro Wars. The stage, according to Noah, is the recent fiscal relief bill in the US, prompting even otherwise pro-stimulus economists to push back. Oliver Blanchard and Lawrence Summers both suggest that $1.9T might be too much of a good thing, while Krugman is sticking to his Keynesian ethos, arguing that Biden’s bill really is ‘disaster relief’, a position that Noah seems to agree with. Replying specifically to Noah’s recent post, he argues that Keynesianism won the theoretical battle a decade ago, leaving only “cranks, charlatans and WSJ Op-ed writers” on the other side. Tyler Cowen chimes in, pointing out that Biden’s post-election fiscal stimulus push has as much to do with populism as it has to do with careful application of Keynesian macroeconomics. As it turns out, this is a position I have a lot of sympathy for.
Read MoreThis week, I’ll stitch together some thoughts on our ticket off the Covid-19 train, also known as the “vaccine”. I am prompted by Georges Pearkes’ challenge to come up with why it might be a bad idea to given people $1500, or another monetary amount, as an incentive to take the vaccine. First things first, it’s very possible that our main problem next year is that we won’t have enough of this thing. Paradoxically, the prospect of a vaccine dealing a killer blow to the virus in the middle of next year has created an incentive for authorities to maintain tighter restrictions in the short run—well into Q1, at least—while we wait for the shot. After all, if the virus is gone tomorrow, the cost of an infection today increases, a lot. A reasonable counterpoint is that governments aren’t masochists, and some form of reopening will happen in Q1, but the point I am getting is simple in the end. Assuming the vaccine is rolled out by early Spring, on the back of a miserably semi-locked down winter, it’s more likely than not that people will be scrambling for a jab, especially in an environment where the vaccine becomes a ticket to otherwise restricted activities via a form of passport. In such a situation, we won’t have to pay people to take the shot. We’ll have to make sure it isn’t hoarded. As for the counterpoint, I am not convinced that the rise of anti-vaxxers—known in the literature as "vaccine hesitancy”—can be applied to predict a threat to the effectiveness of Covid-19 vaccine efforts. That said, early survey evidence suggest that hesitancy might be an issue, especially at the margin where the line between failure and success is drawn.
Read MoreIt’s been a while since I updated these pages, mainly because I have recently moved across the country, back to the Big Smoke, where I am now nestling in the hopefully up-and-coming part of southern London. I will be up and running with my market updates and videos soon enough, but first things first. I have been sitting on this piece, mentally more than anything, for a while, and I thought it would be a nice way to re-start my posting. I have long been thinking about whether it is possible to provide a good quantitative argument in favor of the defunct value equities, or more specifically the value “factor”. I think it is, but as always, I leave to you to judge. In my last post before my temporary hiatus, I made the argument that the vast majority of investors are structurally short volatility. Accepting this premise raises the obvious question; how does one achieve a cheap and effective long vol position? In this post I will try to offer a concrete and quantitative perspective on this question using the simplest tools available to us from finance theory. Before I get to that, though, I want to state the problem more precisely. In a nutshell, the traditional 60/40 portfolio is doing too well. The increasingly concentrated leadership in equity beta centered around the ubiquitous growth factor—essentially U.S. technology firms—and the correlation of this position to the performance of government bonds—driven by structurally falling interest rates—has been a boon for investors. A 60/40 portfolio with a concentration in growth stocks has increased by a factor of almost 4 since 2010, beating the MSCI World by almost 25%, not to mention breezing past the main regional indices—MSCI EM and MSCI Europe—by a factor of 2-to-2.5. That’s great news, but it also puts investors in a bind. If a balanced portfolio is winning on both legs what happens when the tide turns?
Read MoreThe idea of government intervention and demand-side fiscal stimulus was born by Keynes, eradicated by neoclassical economics, lazily reintroduced by the new Keynesians, and is now enjoying a renaissance. It’s fiendishly difficult to judge history in real time, but I would bet that the current shift has momentum, a position that has been strengthened by the response to the Covid-19 crisis. It is perhaps unfair to insist on a marriage between this story and MMT, but it serves as an introduction to the issues at hand. The idea that governments with sovereign Chartalist currencies can’t run out of money, and that this power should be used to achieve full employment, is enticing. It is also, however, naive. MMT easily dodges the main theoretical critique, at least in the current environment. The Phillips Curve probably still exists, but it has also flattened significantly, making it difficult to attack MMT armed with the traditional trade-off between unemployment and inflation. If MMT passes this first test, however, it fails the subsequent trials. The implementation of MMT in today’s economy requires significant shifts in the relationship between fiscal and monetary policymakers and an end to the free flow of capital. My sense is that about half the proponents of the theory don’t have a clue about any of this. The other half understands that MMT requires an end to central bank independence, and a significant reduction in capital mobility. The problem is that this latter group aren’t being honest, and for that reason, I am skeptical about their true motivation. If you want to dial back globalization, the least you can do is to be honest about what this means for households and firms. If you think that an independent central bank is a suboptimal institution, how will the alternative look, and how will it be held accountable?
