A technocratic apolitical presentation (not!)

MMT: new wine in old bottles or ‘voodoo economics’? by Russell Jones and John Llewellyn

Much likeearly-1980s Laffer Curve ‘supply-siders’, MMT’s disciples are often near-messianic in tone, while somewhat vague in exposition. They are prone to presenting their ideas as a pathbreaking, revolutionary, approach to economic analysis and management, that can free policymakers from the shackles of fiscal and monetary orthodoxy.

First, cite your fucking sources. Second, this is a pure ad hominem argument. Third, this is how every critic describes every advocate: how creationists describe evolutionary biologists, religious people describe atheists, capitalists describe socialists, anti-vaxxers describe medical professionals, etc. ad nauseam.

[I]n this piece we seek to present, in a technocratic, apolitical way, a guide to the analytic content of MMT, and the conditions under which it could, or could not, be usefully applied in policymaking.

I would take this disclaimer a little more seriously if you hadn't just shat in the well two paragraphs previously. But whatever, let's push on.

The essential elements of MMT can be summarised as follows:
  • A government that creates its own money generally need not, and will not, default on debt denominated in its own currency.
  • A government deficit is necessarily mirrored by an equivalent private sector surplus.
  • Monetary policy is relatively ineffective in a slump: fiscal policy is more powerful.
  • A government can buy goods and services without the need to collect taxes or issue debt.
  • Through money creation, interest costs can be constrained. Indeed, a substantial and persistent budget deficit can be financed at low, if not near-zero, cost.
  • Government spending and money creation need be limited only to the extent that employment becomes ‘over-full’ and encourages inflation.
  • Inflation, should it arise, can readily be controlled by higher taxation and bond issuance to remove excess liquidity.

I might tweak this a little, but it's not too bad a description. But again, cite your sources, please.

Thus, the core inference and contention of MMT is that the budget deficit and public sector indebtedness should be allowed to adjust to the level necessary to secure full employment. In turn it is suggested that this goal should be achieved through a government-sponsored blanket jobs guarantee, which would act as an utomatic stabiliser. When private sector jobs were plentiful, government spending on the guarantee would be lower, and vice versa. Alternatively, full employment could be achieved by large-scale spending on infrastructure, climate change, and the environment, such as via a ‘Green New Deal’–all financed, if necessary, by the central bank.

The jobs guarantee and large-scale government spending here are not alternatives. MMT advocates argue for both. Other than that, a fair summary.

The truth about MMT is more complicated and less trailblazing than its supporters suggest.

Not a criticism, just another lazy ad hominem. Let's push on to Jones and Llewellyn's actual criticism.

Indeed, it looks very much like the ‘Functional Finance(FF)’gospel preached by Abba Lernerin the late 1930s and 1940s.

What?! MMT Scholars, who have PhDs in economics, have, gasp! read Abba Lerner?! Say it ain't so!

For example (since I actually will cite sources), Here's L. Randall Wray in MMT Responds to Brad DeLong’s Challenge:
What [MMT scholars] really like was Lerner’s application of Functional Finance to the budgeting process. The budget should be functional, not sound. That is, to achieve a functional purpose rather than to balance taxes and spending.

Or just search for Lerner on NEP.

Furthermore, Lerner isn't the first. He has predecessors.

Back to Jones and Llewellyn.

[Keynes] considered that Lerner lacked practical judgement and intuition, and paid insufficient heed to what he described as the public’s ‘allergy to extremes’.

Yet another ad hominem. Is this how you do technocratic apolitical examination? I think I was doing it wrong all those years in college and grad school studying economics.

[T]he policy inferences of MMT need to be considered seriously. At the very least, they do not compare unfavourably with calls for fiscal and monetary rectitude that are grounded either in narrow accounting logic or myopic adherence to the quantity theory of money.

I concur! Given that "calls for fiscal and monetary rectitude" have dominated the conversation over government spending since I've been alive, MMT sound pretty trailblazing just on that point alone.

MMT, like FF (and in common wit hmuch US-led analysis) is based implicitly on a closed-economy model. It makes no allowance for the possibility of monetary expansion causing the exchange rate to fall rapidly.

No it isn't and yes it does. See MMP #34 Functional Finance and Exchange Rate Regimes: The Twin Deficits Debate. Y'all have heard of Google, right?

Also, for a large country such as the US, exchange rate problems are relatively trivial. MMT scholars have given a lot of thought to the applications of MMT for smaller, outside-debt constrained countries.

Jones and Llewellyn:

MMT overlooks the potential for monetary expansion and an extended period of low interest rates to create the conditions for domestic financial instability, excess, and perhaps disaster.

Surprisingly, MMT scholars have heard of Hyman Minsky. Google is your friend.

MMT’s disciples pay little attention to the structural component of unemployment, which is unlikely to prove responsive to stimulus of demand and, more likely, raise inflation.

What. The. Fuck. The whole point of the Jobs Guarantee is that ordinary stimulus will not cure structural unemployment. Seriously, guys, you have to at least read the textbook, or you'll fail the class.

For example, from the MMT Primer:

OK, explain to me how pumping up the demand for higher skilled and educated workers—setting off a bidding war for them—will cause jobs to trickle down to the less skilled and less educated workers WITHOUT causing wages and prices to rise.

Jones and Llewellyn:

They say little about the effects on wealth distribution of a reliance on monetary finance.

Why should they? They talk about the salutatory effects on wealth distribution of fiscal policy, i.e. taxing the shit out of the rich because, you know, fuck those guys.

They ignore the vexed issue of moral hazard. The disruption of the connection between government decisions on the size of its budget deficit and the willingness of the private sector to fund that deficit at interest rates that it deems reasonable destroys at a stroke one of the most important disciplines the market imposes on politicians.

This statement requires a little more depth of response. First of all, no economist ever just ignores moral hazard; however, we might have different opinions on where and how much there is. And we already know Jones and Llewellyn have not read the textbook, so we have little confidence that they have read comprehensively enough to find out what isn't there.

I can't nail down a specific quotation, but the whole point of MMT, at least as I read it, is that MMT scholars don't want the "private sector" (i.e. the billionaires) to discipline the government, they want the government to discipline the billionaires.

Where's the real moral hazard? In elected politicians who have to maintain legitimacy and popular support to gain reelection? Or in a bunch of rich people who will do anything to retain their power?

Finally,it is inescapable that debt accumulation cannot go on indefinitely

This is just flat-out not true. Or, more precisely, debt accumulation can go on as long as economic growth goes on or until we move away from a money-based economic system entirely, in which case debt becomes meaningless.

Free speech and academia, yet again

I will say this yet again, because it's important.

Academia is (among other things) a place where we separate good ideas from bad. This function requires that academics openly discuss questionable subjects and ideas with a as much dispassion and "objectivity" as we can manage.

However, at some point, academics should and actually do make some decisions: we find some ideas to be legitimately good, and promote those ideas, and we find some ideas legitimately bad, and we deprecate those ideas. And if you want to discuss a bad idea on a college campus, the burden of proof is on the claimant to show that there's something so novel and compelling about the idea that the previous judgement should be suspended.

The idea that women are in any way inherently inferior to or even very different from men (other than reproductive biology and trivial aspects of athletics and heavy manual labor) is one such legitimately Bad Idea. The idea that people of some races are inherently inferior to other races is another such Bad Idea. The idea that people with atypical sexual or gender orientation are in any way inferior to those with typical orientation is yet another. This list is not exhaustive: There are any number of completely discredited ideas that have no place in a university.

With apologies to Monty Python, sexism, racism, etc. are not pining for more critical investigation. They are dead. They've passed on. These ideas are no more. They have ceased to be. They've expired and gone to meet their maker. They are bereft of life, they rest in peace. If racists hadn't nailed these ideas to the perch they'd be pushing up the daisies. They're metabolic processes are now history. They're off the twig. Kicked the bucket, shuffled off their mortal coil, run down the curtain and joined the bleedin' choir invisible. They are ex-ideas.

Do I make myself clear?

No one gives a fuck if some dumbass student writes a stupid sexist paper in Comp I or if some mossbacked tenured professor publishes reactionary racist drivel in an obscure journal. De minimus non curat lex.

But it's an intolerable affront not just to the sensibilities of minority students but also to those who take seriously the academic pursuit of truth for an actual university to invite a dumbfuck racist like Charles Murray or a narcissistic poseur like Milo Yiannopoulos to speak, as if these morons could breathe any sort of intellectual life into long dead ideas. The only possible reason to invite people like this is that the university wishes to promote racism, sexism, or some other long-discredited idea.

The history of the most brutal violence to control and oppress women, people of color, etc. ad nauseam means that universities must take bullying and hostility with the utmost seriousness. A campus is not 8chan; it is a professional environment. It should require literally zero thought to hold that the right of Black students to fully participate in academia squashes the right of some Aryan Brotherhood frat-boy jerk to yell "n****r" in the quad.

Good fucking grief. Why is this still an issue?

Modern Monetary Theory continues to gain traction in the US

MMT asks that instead of worrying about their balance sheets, governments start looking at ways to use the resources at their disposal in the most efficient way possible. According to the theory, generating full employment, creating a more equal society and fortifying our education systems are all possible without causing rampant inflation. It is not a question of being able to afford it – it is a question of political will.

Where will we get the cash?

In Need Money? Hey, Just Print It, Charlotte Hays says that the "only way to raise the cash for Medicare for All, full employment, and vast infrastructure work" is to "just print more money."

Well, it's not the only way to raise the cash, but it is a way, perhaps the best way. If the only thing we need is cash, then yes, we can indeed just print more money. The government needs neither to coerce, cajole, nor appease the people who have money in order to obtain money to implement its goals. The government can indeed just print it.

But of course we need more than just cash. We need to allocate labor and capital away from other uses and towards the vast infrastructure work that needs to be done. The question to ask is not where to get the money, but what do we have to give up to get Medicare for All, full employment, and the Green New Deal. And, of course, what do we give up if we don't get them?

Medicare for All is a no-brainer. We give up a bloated insurance bureaucracy that spends obscene amounts of labor to deny people health care. We give up monopolistic hospitals squeezing patients for every dime they have for routine treatment. Maybe a lot of physicians will no longer be extremely wealthy. I'm happy to let those assholes pay the cost of Medicare for All.

What do we give up to get full employment? By definition, nothing. If we give a person a job, we give up that person sitting at home doing nothing, when they do not want to sit at home doing nothing. The individual gains, and society gains by getting additional productive labor. (If a person is incapable of doing nothing sufficiently productive to justify their life, then that person is disabled, and we have a moral obligation to support them, unless you want to advocate for euthanasia for "undesirables".)

Which leaves the "vast infrastructure work". First, what do we give up by not undertaking the work, however vast, of reducing carbon and other greenhouse gas emissions? Everything, or nearly everything. We might at worst render the surface of the Earth uninhabitable and unfit for any kind of advanced civilization. A few nomadic hunter-gatherers might survive with stone-age technology, but nothing of civilization will remain. So if we have to give up anything less than civilization itself to fix global warming, the cost will be worth it.

But what do we really have to give up? I don't rightly know. It could be a lot. It could be that the industrialized nations have to give up a considerable standard of living. We might have to consume a lot less. Not the greatest, but better than drowning in our own shit. But it could be very little or even nothing. If vast infrastructure spending promotes long-run economic growth, it very well could pay for itself in increased productivity. Presently, long-run economic growth is extremely poor, and the returns to what little economic growth we have is primarily going to the ultra-rich. If infrastructure spending does nothing else but transfer wealth and income from the 1% and 0.1% to workers, I would count that a gain, not a cost.

Whether or not the government should take money away from ultra-rich people is a different question? I think so, yes. But the government should take money away from them not because we need that money to do something else, but because it is not in the public interest for the ultra-rich to have too much economic power.

Palley on MMT part 1

I'm going to go through Thomas Palley's What’s Wrong With Modern Money Theory (MMT): A Critical Primer page by page and examine Palley's arguments. I won't bother commenting on his descriptions and background material, which seem unobjectionable. All references are to the above unless specifically noted.

Recently, MMT proponents have begun walking-back the idea that functional finance is central to MMT. The purpose of the walk-back appears to be to deny that taxes are needed at full employment to neutralize inflationary excess demand caused by excessive government spending. Three points follow. First, it is fundamentally dishonest to deny the long-standing central role of functional finance in MMT’s argument (see for instance, Kelton, 1999). Second, removing taxes means MMT has now shifted to the arguing that inflation control should be conducted via rationing, price controls, and other administrative measures (Wray, comments at Eastern Economic Association, March 2019). Third, it illustrates the difficulty of understanding and debating MMT as its proponents constantly change their positions. (footnote 2, p. 4)

This is unwarranted well-poisoning. If Pally wants to ascribe a purpose or motive to a body of writing, he should offer an argument in addition to citing the evidence. If he wants to accuse proponents of dishonesty, he should cite their dishonesty. Do MMT proponents really argue that "inflation control should be conducted via rationing, price controls, and other administrative measures"? If so, a written reference, not a reference to an oral presentation seems required.

MMT’s main macroeconomic claim to fame rests on its declaration regarding government’s ability to finance spending without recourse to taxation by issuing money. In fact, government’s ability to create money to finance spending has long been widely recognized by all economists, who have also long recognized that ability gives government considerable extra financial and policy space. (p. 5)

Damned if you do, damned if you don't. How is it a criticism that MMT scholars advocate a position that is "widely recognized by all economists"? And why should I believe Palley that this apparently obvious proposition is MMT's "main macroeconomic claim to fame"? Again, Palley offers no citation to show that MMT scholars believe they themselves have discovered governments' ability to create money.

As regards injecting state money to pay taxes, MMT is strictly wrong with its claim that the public cannot pay taxes until government has first spent. In fact, the central bank is the source of such money. (p. 6)

The Federal Reserve Bank is part of the government. I do not know of a central bank in any industrialized democracy that does not have authority granted by the legislature.

Palley offers as "evidence" a quotation from Wray:
In principle, then, the government first spends fiat money....Once the government has spent, then the fiat money is available to be transferred to the government to meet tax liabilities. As a matter of logic, the public cannot pay fiat money to the government to meet tax liabilities until the government has paid out fiat money to the public. (qtd. footnote 5, p. 6)
But Wray explicitly makes an in principle argument. It is merely a "terminological objection" (see below) to argue about which organ of the government, the legislature directly through spending or the central bank autonomously exercising spending power granted by the legislature, creates the money.

Palley also asserts that Jo Michell "claims MMT does not say government spending is needed to pay taxes" (footnote 6, p. 7). The cited post does not appear to support this assertion. Michell says, "[G]overnment spending comes before taxation . . . is sort of true but also not particularly interesting." What Michell argues is not part of MMT is that "without [government deficits] the means to make settlement would not exist in our economy."

MMT focuses on accounting and stock-flow relations. . . . [T]hose accounting and stock-flow relations have long been understood by Keynesian and neo-Keynesian economists. (p. 7)

Again, it should not be a criticism that MMT scholars agree with orthodox economists.

MMT objects to [the government budget constraint] being called a constraint as if government were a household. However, that is a terminological objection. (p. 7)

Not all terminological objections are created equal. Terminology should clarify, not obfuscate. Palley's terminological objection above obfuscates that the Fed is a part of the government; MMT's terminological objection clarifies: If government is not actually constrained by a budget, it's disingenuous at best to say the government has a budget constraint.

MMT sees the effects of increasing government financial obligations as entirely benign, and policymakers can use the financial space to costlessly boost demand and push the economy to full employment. There are no negative consequences from increasing government financial obligations; no conflicts with other policy objectives; and no policy implementation problems. (p. 7-8)

[citation needed]

As shown below, MMT’s macroeconomic policy assertions follow from its oversimplified and incomplete Keynesian analysis. The lack of a dynamic economic model with behavioral content is a glaring professional failure. (p. 8)

I don't know about this one. My general training in advanced macro is woefully inadequate. Still, the orthodox dynamic macroeconomic models (DSGE models) seems to attract their share of criticism.

Unfortunately, instead of addressing that failure, MMT proponents have responded by claiming critics either do not understand it or have misrepresented it. (p. 8)

Or it could be that critics don't actually understand MMT and are actually misrepresenting it.

The difficulty of confronting MMT about those failings is compounded by its practice of walking back its positions and adopting those of its critics without acknowledgment. (p. 8)

What? MMT scholars might clarify their positions, correct mistakes, or even, gasp! change their minds?!

[M]oney financed budget deficits drive the economy to full employment by increasing wealth and AD. That makes it critical there be institutional arrangements for closing the deficit once full employment is reached to avoid inflationary excess. However, MMT relies on a highly simplified and implausible political economy in its attempt to address that problem. Thus, it assumes taxes can be abruptly and precisely raised at full employment to contain excess demand, when the reality is taxes are politically contested and difficult to raise. Long ago, Friedman (1961) argued that fiscal policy was impractical for “fine-tuning” stabilization policy owing to inside (decision) and outside (implementation) lags. Those lags mean policy implementation is likely to be poorly timed, so much so that it could amplify the business cycle rather than dampen it. (p. 9)

These criticisms are kinda true, especially the latter concerning lags. However, they really amount to the unobjectionable claim that regardless of one's models, managing a large economy is a Hard Problem. Friedman et al. argued against any kind of fine-tuning, not just via fiscal policy but monetary policy as well.

But yes. MMT does need good models concerning how to raise taxes effectively to address inflation. Maybe they have them. I am not at all confident that Palley has made an exhaustive search of the literature to find them.

Absent budget discipline, spending and deficits would tend to ratchet upward owing to the political attraction of money financed deficit spending and the political aversion to higher taxes. (p. 10)

Maybe, maybe not. I'm not at all convinced that the above political attractions and aversions are anything more than artifacts of our dysfunctional political system exacerbated by inequality. And I'm not at all convinced that an artificial budget discipline, denying truths that have "long been widely recognized by all economists, who have also long recognized that ability gives government considerable extra financial and policy space" (p. 5) is the only alternative.

Regardless, part of economics is not just what is feasible in the immediate present but also what is theoretically possible. Taken in that spirit, yes, MMT needs to come up with institutional mechanisms that can use taxes effectively to control inflation, which does not sound like an impossible task.

Another political economy critique (Lavoie, 2014) is that central banks and fiscal authorities are institutionally separated in most economies, but MMT ignores this and treats them as a unified decision maker. The separation is usually justified on public choice grounds that politicians have an inclination to inflationary monetary populism, and separation of fiscal and monetary powers helps prevent that. (p. 10)

This critique is petty. Institutional separation seems inconsequential, and the Fed and Treasury usually coordinate their actions. Regardless, institutional separation is at best one way of avoiding "inflationary monetary populism", but it's hardly the only possible way.

Palley is making a fundamentally flawed argument, which is at least a step up from the beginning of the paper. Anything can be done poorly — White can lose at chess in two moves — so the argument that X might not work is unintersting. The argument needs to be that X cannot work, or be extraordinarily difficult to make work even under favorable conditions.

And heterodox economics is heterodox. That we currently solve certain problems one way is not an argument that that way is the only way, especially when the current way really seems to be failing badly.

Only a third of the way through, and I'm throughly unimpressed with Palley's critique.

The Job Guarantee

Many Modern Monetary Theory scholars* advocate a Job Guarantee (JG). I like this idea.

*I am not a scholar of MMT. Any errors are my own.

As I understand it, the JG means that the government is the employer of last resort. Any adult citizen (or resident) can walk into the government job office and have a job by the next day. The job will pay a reasonable minimum wage and entail no long term commitment from the job seeker. The job might be matched to the seeker's skills, and common-skilled jobs would be available to anyone. These would still be jobs, and one must actually show up and do the work to get paid. The government pays the JG wages, creating money as needed (taxing it back out later if necessary).

The idea behind the JG is first that if non-disabled working age residents have an obligation to contribute to the social product, there is a corresponding social obligation to provide them a reasonable opportunity to do so.

Second, the JG acts as an automatic stabilizer. Automatic stabilizers avoid the lags inherent in more deliberate government stimulus. When there's a recession, people laid off will immediately seek JG jobs to pay their bills, automatically generating stimulus spending. When the economy recovers, people will eventually leave JG jobs for private-sector jobs, lowering government spending.

I don't think we need to choose between a) the Job Guarantee, b) organized, deliberate stimulus requiring permanent skilled employment, and c) a Universal Basic Income. Why not have all three as needed?

I don't think JG jobs need to be "make-work". They will probably be relatively low-quality jobs, since some (most?) JG jobs have to be available to people with only common skills. But the private sector has no small few shitty jobs, made worse by the fact that employers have little democratic oversight.

We could offer job training jobs: if we are low on welders, it is government money well spent to teach more people how to weld. It might even be a good idea to send some people to college as JG jobs. At the very least, there's always something that needs to be cleaned up, washed, or painted. There's no shortage of useful work to be done, even if it's not profitable.

Although there will probably be some people who can or want to contribute only the simplest, most common-skilled labor, we want to make sure that we don't have a permanent underclass of people fit only for JG jobs. We also want to ensure that JG workers are not oppressed or taken advantage of: by definition, JG workers would be people with relatively few outside options.

These requirements could be fulfilled mostly by prudent and transparent administration. Additionally, we can establish a JG union, so that JG workers can bargain collectively at least over working conditions. We can allow non-profit organizations to employ JG workers, with workers' wages paid for by the government. Non-profits would be required to be non-discriminatory, and we might restrict them to requiring only common skills. Allowing a range of non-profits would give JG workers some choices.

MMT and political economy

One criticism of Modern Monetary Theory* is that raising taxes to control inflation is politically difficult. I think this criticism is correct in a sense, but it's incorrect in a more important sense.

*I am not an academic scholar of MMT. Any mistakes in descriptions and analyses here are my own and should not be attributed to scholars in the discipline.

Politics is a legitimate topic of study by economists, and it's correct to say that raising taxes is difficult given current political institutions. It follows that more abstract, technocratic, and less openly partisan monetary policy is probably a less bad choice today to control inflation. Indeed, I don't think MMT is a particularly valuable economic theory given current political institutions. Of course, I think our current political institutions are terrible. And that's where MMT has real value in my opinion: even if you don't like socialism, MMT is, I think, a better theoretical framework for a much more progressive agenda, an agenda that will require substantial change — a revolution if you like — in our political institutions.

One important aspect of MMT is that it subverts the notion that our capitalist democratic republics are built on apolitical, ahistorical economic truths. They are not. To no small extent, economics is just describes how our political economy in a particular historical social context actually works. A different political economy would work differently.

Simply adopting MMT and changing nothing else would have at best no effect and at worst fuck things up royally. We can't fight fascism with economic theories. We have to rethink and re-implement our whole political economy at a fundamental level. That's not going to be an easy fight, and it won't be economists who do the bulk of the fighting. However, I think having a set of valid progressive economic theories has substantial value, and MMT shows a lot of promise of delivering that value.

Taxes and government production

There is a paradox in how we talk about "paying for" what the government produces. Yes, taxes do pay for government production. And no, taxes do not pay for government production. Wait, what?

As best I can tell, Modern Monetary Theory scholars* stress the idea that taxes do not pay for government produces in a "financial" sense: unlike a household or a firm, government does not collect taxes to obtain money to spend on government production. A household or a firm must obtain money, via revenue, borrowing, or theft, before it can spend it. A government need not do so; to the extent that the government says it does need to collect money before it spends it, the government is at best disingenuous and at worst deceptive. Financially — and this qualifier is crucial — the government spends whatever it chooses to spend, regardless of ex ante taxation or borrowing. A household or firm cannot choose to spend money it has not already obtained; a government might choose to spend only the money it has previously obtained, but it can choose not to.

*I will repeat my usual disclaimer: I am not a scholar of MMT; any mistakes in my present description of MMT ideas are my own.

I suspect that MMT scholars stress this financial freedom precisely because not only governments but orthodox economists, while they formally acknowledge government's financial freedom, either don't understand this freedom — a lot of economic theory depends on a financial budget constraint to make any kind of sense — or they don't want people to intuitively grasp the government's financial power. What is to become of the captains of industry, the titans of finance, if their years of hard work accumulating money can be duplicated or undone in seconds by some faceless downclass bureaucrat in a cheap suit? Worse yet, what if the unwashed masses catch on and start, gasp! voting on that basis? No, such nonsense simply will not do.

But of course even that the government has financial freedom, i.e. it can spend as much or as little money as it pleases, the government does not have "real" freedom: it cannot choose to escape opportunity costs. Especially when the economy is at full employment, anything the government creates money to produce means using that money to reallocate real labor and capital away from other production. At full employment, government spending on one thing, regardless of the source of the spending, means giving up something else.

Governments usually produce public goods, and the opportunity costs of public goods are harder to distribute than are the opportunity costs of private goods. Suppose a firm produces a private good, a new and improved widget with extra frobulousness. The firm improves society if and only if individual consumers individually choose to buy its widgets instead of now unfashionable and obsolete doodads and gewgaws. Ideally, the private firm merely poses the option: the individual consumer decides whether the new option is worth the opportunity cost, and what the opportunity cost actually is in real terms. And we know when the firm produces the optimal quantity of new and improved widgets precisely when the marginal consumer is indifferent between the new widget and the next best choice. With apologies to Landseer and à Kempis, the firm proposes, the consumer disposes.

Public goods simply do not work that way, as economists orthodox and heterodox all know: the math is clear and unequivocal. Individual consumers cannot individually choose how much of a public good they receive: all consumers receive benefit from all production of a public good, regardless of their individual preferences. If the government produces clean air, I cannot help but breathe it.

Thus, the government must distribute the opportunity costs. They can do so in two ways: increase or keep constant the supply of money and let everyone's money purchase less stuff per dollar, i.e. no taxation and some inflation, or decrease the supply and let everyone's money retain its purchasing power, i.e. some taxation and no inflation, i.e. price stability.* So in the sense of the distribution of opportunity costs, taxes do in a sense "pay for" government production.

*Strictly speaking, there is a continuum between zero taxation and zero inflation.

On the one hand, government has financial freedom; on the other hand, the government has real constraints. On the gripping hand, there are some circumstances where government spending neither requires taxation nor generates inflation (or at least not nearly as much as it might otherwise do). When government spending promotes short run or long run real economic growth, the economic growth itself "pays for" government spending in both the financial and real sense. In the short run, when real economic output is below potential — i.e. under recessionary conditions of less than full employment, especially when the recession has been caused or exacerbated by collapse of the money supply as during the Great Depression — government spending causes an increase in both financial and real economic activity. The injected money just keeps flowing; it does not (all) need to be leaked back out by taxation, and the increase in real economic activity absorbs the extra spending without causing (too much) inflation.

Similarly too with long run economic growth. Government spending in research and development, especially for the military, initiates much (if not almost all) of the growth of inventive technology. (See e.g. Doing Capitalism in the Innovation Economy by William H. Janeway.) Again, the spending is "paid for" by the increase in real economic activity.

Many critics of MMT argue that the above exposition is just warmed-over bog-standard Keynesian macro. Perhaps. If so, the profession of economics has been trying to at best downplay and at worst obfuscate its importance and relevance not just to the general public but to undergraduate students of economics. I know: I just finished an undergraduate and graduate economics education, and I found the claims of MMT were both shocking and obvious in retrospect.

Even the Holy Bearded One says in his own Macroeconomics textbook that the government should run a balanced budget on average (my copy is in my office; citation to follow). But this cannot be so. In an ideal world where we always have zero inflation and no short-term fluctuations, to preserve perfect price stability, the amount of money flowing through the economy* must increase as long-run potential output increases. Since money cannot flow arbitrarily quickly, the overall supply must increase, so either the banks create it or the government has to create new money.

*Technically the money supply times the velocity of money.

We could, I suppose, allow the private banking system complete control over the flow of money. When unconstrained by government regulation, complete private control of money generally has not worked worked all that well. Seriously. It's a Bad Idea. If we want to make the foundation of economy the government's power to collect taxes, then the government must run a deficit on average.

MMT, money, and opportunity costs

Often, if we want one thing, there is some other thing we can't have. Economists call this an opportunity cost. We study the things we must choose between, and how people make those choices.

I am an economist. Opportunity costs are my faith, my creed, my dogma, my mantra. I believe. TANSTAAFL!

Money is a socially constructed institution (or collection of institutions) to quantify, manage, and distribute real opportunity costs. But money is not by itself an opportunity cost; to equate money and opportunity costs is to mistake the map for the territory.

I have been reading the "surface" of Modern Monetary Theory — popularizations, blog posts, etc. — for almost all of my career as an economist-in-training. And what I like about MMT is that these theorists make clear the institutional, socially constructed role of money as a mapping of opportunity costs.

Every popularization of MMT that I have read promotes the same message, a message that disturbs my economist's faith not even a little: production is constrained by real resources, i.e. natural resources and human labor; production is not constrained by money by itself.

MMT advocates do say there are things we can have cheap, and in this, yes, they say nothing new, nothing that is not part of bog standard orthodox economics. If there are idle resources, unused factories, unemployed labor, we can put those resources to productive use give up little more than excessive unwanted leisure.

I have never heard any MMT theorist ever say that we can have anything "for free". Never. Not once. Maybe I'm wrong. I will dig into the literature and find out.

But for now, the onus of any critic of MMT, at least if they're trying to convince me personally, is to convince me that MMT advocates really do say that we can have anything for free. As yet, none have done so.

It is a much different thing to say that money by itself should not constrain a society, especially a government. Technically, orthodox economists tepidly agree, but they seem to inexorably conflate money and real opportunity costs. MMT advocates are the only people who absolutely insist on conceptually separating money and opportunity costs. Even if there is nothing else new about MMT, even if all of their economic theories fall short of figuring out precisely how to quantify, and distribute real opportunity costs, MMT is still worthwhile because the orthodox view of money has failed us. We must rethink money.

The neoliberal project to make everything subject to money and markets, even were it undertaken in good faith, has decisively failed. Whatever good it has delivered has come at the cost of economic stagnation, intolerable inequality, nascent fascism, and ecological catastrophe.

Even if MMT has found nothing new, they are at least looking. And we must look, because we cannot keep what we have now.

Modern Monetary Theory

I don't remember when I first heard about Modern Monetary Theory (MMT). It was either just before or just after I began my academic economics education in 2010. I thought it sounded interesting: mostly standard Keynesian economics, which is good, because Keynes is good. The main reason I like MMT (which should not be confused with what MMT scholars believe to be their most important contributions) is that MMT stands in stark contrast to the balanced budget mania I've been subject to my entire life, before, after, and during my education. I have been told time and again that Government Spending is Very Very Dangerous. Bankruptcy! Default! Runaway Inflation! Bond Vigilantes! Socialism! Cats and Dogs Living Together! The MMT story is completely the opposite: we can't go crazy with it, but government spending by itself is no dig deal if we're reasonably careful about (too much) inflation. On the other hand, nothing about MMT made me want to quit my job, give all my possessions to the poor, and make a holy pilgrimage to Jerusalem UMKC.

Flash back to '99-2000 to around 2005. I started my informal education in philosophy and argument talking about religion on the internet. The nice thing about religion is that they have spent thousands of years developing literally all the shitty fallacious bad-faith arguments for a completely indefensible proposition. I've seen them all, and I can smell bullshit a mile away.

Cut to today. Bernie Sanders hired Dr. Stephanie Kelton, a prominent MMT scholar, as his economic advisor. Alexandria Ocasio-Cortez is rumored* to be hooked up with MMT economists. MMT seems to be gaining prominence on the progressive left.

*relative to my personal knowledge.

In response, I have seen a fair few traditional academic economists, economists that I like and admire, writing polemics against MMT. And with few exceptions, their polemics have reeked of the same sort of bullshit religious arguments I spent the early part of this millennium taking apart. So that makes me curious. Really, it is Krugman, DeLong, and Palley more than Wray and Kelton who have really sparked my interest in MMT.

(So too with Bernie in 2018. Most of the mainstream Democratic party arguments against Bernie and for Clinton also reeked of bullshit. Bernie Bros? Are you fucking kidding me?)

So I'm going to investigate further. I have an MA in economics, so I think I can sort out the primary literature. We'll see how that works out. You can track my progress on my new MMT Page.

There a continuum of possibilities between the extremes of MMT is all that and a bag of chips and MMT is completely full of shit. But even if my evaluation falls toward the latter end of the continuum, I have to ask why MMT opponents are using such lousy arguments. Bad arguments — even against a bad idea — are a sign of either being lazy, ignorant, or stupid or of a hidden agenda.

Of course I suspect a hidden agenda. I maintain that the professional-managerial class, represented by the orthodox Democratic party leadership, are not themselves fascists, but they would prefer fascism to socialism; heck, I think they would prefer fascism to social democracy/welfare capitalism. Even if the technical economics of MMT are bad, I suspect that opponents relatively unconcerned about the technical failings and much more concerned that MMT would legitimize social democracy.

But proving bad intent is very difficult and not really dispositive. So my task for the coming year is to dive into the primary literature, both for and against MMT, come to my own conclusions, and share my analysis and conclusions with you, gentle readers.

Unpleasant Keynsian arithmetic

In "Macroeconomics vs Modern Money Theory: Some unpleasant Keynesian arithmetic," Thomas Palley artfully demolishes a straw man of such egregious flimsiness that it is difficult to avoid concluding bad faith.

Referring to Kelton et al., We Can Pay For A Green New Deal, Palley claims, "Proponents of MMT assert [financing a Green New Deal] is a non-problem and the programs can be financed by “printing” money and without causing higher inflation." However, Kelton et al. add an important condition, arguing that deficit financed programs are not inflationary so long as we are not at full employment. Palley simply repeats Kelton et al. own assertion as if he were correcting their error.

Kelton et al.:
Despite lawmakers’ stated fears, larger public deficits are not inherently inflationary. As long as government spending doesn’t cap out the full productive capacity of the economy ― what economists call “full employment” ― it won’t spin prices out of control. Inflation isn’t triggered by the amount of money the government creates but by the availability of biophysical resources that money tries to go out and buy ― like land, trees, water, minerals and human labor. [emphasis added]

As has long been known by Keynesians(Blinder and Solow, 1973), money financed deficits can be used to finance programs when the economy is away from the full employment -vinflation boundary.vHowever, that space will be temporaryvto the extent deficits increase real financial wealth and automatically drive the economy to full employment, at which stage there will be an inflationary gap. . . . There is a money financed free lunch as long as the economy is below full employment, but the free lunch inevitably disappears.

Palley continues to misrepresent MMT scholars. When calculating his "unpleasant Keynesian arithmetic", he includes Medicare for all and free college tuition. However, he does not cite anything to support the implicit assertion that MMT scholars advocate using deficit spending to finance Medicare for all or free college tuition. It seems blindingly obvious that the best way finance Medicare for all is through taxes to replace insurance payments.

It is a core tenet of MMT that spending precedes taxation, but requires subsequent taxation to prevent inflation at full employment. But this reordering is an entirely different position than the position that MMT critics attribute to MMT proponents, i.e. that MMT says that we can have unlimited government spending without inflation.
