I’ve written a longform critique of Modern Monetary Theory, that you can find here.
I’ve noticed that a large contingent of the left have become increasingly (ostensibly) anti-capitalist as of late, more than just a fringe segment as it may have been a decade or so ago. Modern left wing discourse, when not focusing on social justice issues, has a tendency to frame anything bad that happens economically as part of some set of fundamental unresolvable flaws in capitalism, rather than a flaw with the current more specific economic policies pursued by governments today.
I don’t quite understand this tendency or urge to want deeply radical or revolutionary change to a system, including abolishing private ownership of capital, especially if you don’t have some well scrutinized and empirically validated plan as to how exactly society will be organized after the revolution. Of course I’m not sure that many on the left are really ready to jump into the abyss – but rather, they’ll choose to talk as if they do, responding to current economic issues by lamenting internal contradictions in capitalism and advocating vague kinds of class warfare, without seeing the need to propose any specific practical policies that could remedy the issues.
To put it another way, the situation is often presented as a binary choice, either you have the current system – with all the existing inequality, environmental destruction and poverty that currently exists – or we abolish capitalism.
To which I say, not so fast! There are surely near infinitely many ways you can configure society that can still be reasonably called ‘capitalist’. I highly doubt anyone has exhaustively considered every possible configuration and concluded they all are terrible.
If we reasonably define capitalism as a system where capital (or the ‘means to production’) is typically (though not always) owned privately, and where private citizens and businesses can trade goods and services with each other, then it’s easy to come up with a huge list of measures that can be considered before you even think about abolishing capitalism completely. The left should be reminded that the following policies are all compatible with this definition of capitalism, and these are all measures the left can still push for or support:
- Higher and more progressive taxation, incl higher inheritance tax
- More benefits for the vulnerable
- Higher minimum wage or living wage
- More laws in support of unions and against monopolies
- More environmental regulations
- Emissions caps
- National healthcare
- Stricter regulations
- Bans on lobbying and large campaign donations
- More labour protection laws
- Basic income
- Publicly owned investment banks
- Formation of more cooperatives and non profits
- Breaking up of large corporations and better anti-trust law
- Public works programs
- Job Guarantee
- Wealth tax
My plea to the left is simply this: why not focus on pushing for these kinds of policies first, and if, after all of these policies have been implemented, the system is still unbearable for you, then you can talk of class warfare, abolishing capitalism and jumping straight into communism/anarchism/full socialism etc… ? Why continue to frame contemporary debate as the binary choice of ‘status quo’ or abolish capitalism, when there are all these policies in between that we can still try? Why not reject binary political economy and embrace capital fluidity?
VoxEU just published an article by various German economists defending Germany’s hard stance on Greece here.
They begin by noting the staggering size of the Greek deficit in 2009/10 (15% of GDP, 10% net of interest payments), and go on to say: “Given these fundamentals there was only one policy option – Greece had to balance its budget, and the current account needed to be turned into a surplus, to be able to service both its private and public debt.”
Wait hold on, this may sound absolutely nuts, but is that an automatic given? Yes, Greece needed stop its debt to GDP ratio from exploding, but does this immediately imply a balanced budget? We know that a balanced budget is not necessarily needed to maintain a steady or even declining debt to GDP ratio, as long as the economy experiences normal growth. On the other hand, Greece does not control its own money supply, thus it would have no independent monetary means of curtailing the rapid rise on interest rates it would suffer if were to try and continuously roll over its high level of borrowing. So, true, perhaps if you’re constrained by a currency union and lenders have so little faith in you, the very high interest rates would make maintaining a budget deficit infeasible.
Perhaps then, the rational response to this problem is to suggest not that an economy as weak as Greece should engage in immediate heavy austerity, and risk a catastrophic fall in output, in order to maintain a surplus. Rather, perhaps Greece should leave the Eurozone in an orderly fashion, regain monetary sovereignty, engage in rational structured default of its external foreign denominated debts, and attempt to start again with a more accommodating monetary policy.
Of course, the risk in this case is a catastrophic rise in the price level. The authors however don’t do enough to explain why one risk is preferable to another, and what the risk of the latter actually is.
The paper continues to note that other countries that have experienced currency crises, regardless of whether they managed to defend a fixed exchange rate or not, also suffered deep slumps in output and a change from current account deficit to current account surplus. I struggle to see the relevance of this, a country entering a recession will inevitably experience a decrease in its current account deficit as foreign investors begin to pull out of the economy. Furthermore, nobody denies that an adjustment was necessary, I don’t believe anyone was advocating some kind of free lunch theory where Greece would have avoided recession altogether. Instead, people are worried about Greece’s long term future.
The authors continue to note:
“Unfortunately, any sign of stability has effectively been wiped away by the new Greek government. Blaming the recent capital flight from Greece and the sharp increase in government yield spreads on anything else but the election-campaign announcements and post-election decisions of Syriza would be ludicrous.”
I agree with this, and this is unfortunate.
The paper continues to comment:
” As a result, Greece enjoys quite palatable debt service requirements, with an average interest rate of 2.3% and interest payments of 4% of GDP, and the major share of interest payments is even deferred until the early 2020s”
It is true that Greece’s interest burden is much lower than many let on. This fact alone might have supported their next statement, that: ” a debt relief of public creditors could not substantially improve the comfortable state of the Greek government, let alone be justified easily vis-à-vis its lenders.” But their ‘comfortable state’ ignores how extremely uncomfortable it is politically to have such a high level of foreign denominated debt, and how much it spooks non troika lenders, as revealed by how high they require Greek bond yields to be. Having to rely on continued bailouts from the troika is humiliating and ties their hands in terms of many policies they might want to enact. You could say it’s politically unsustainable (evidently) and It follows that debt relief might relieve these pressures a little, and might make investors a little more confident. Further, if interest burden is still so low, and Greece’s situation really is as ‘comfortable’ as the authors state, then would there really be substantial harm in allowing Greece’s primary surplus to fall a little, in order to stimulate some growth in the economy, as advocated for instance by Krugman? Again, these authors have failed to explain why this would result in a less sustainable position in the long term.
Lastly, the authors argue that while the risk of economic contagion from a Grexit is minimal, the risk of political contagion is high, with potentially disastrous consequences. This may be true, but I fail to see how this supports the notion that the path Greece & the troika took from 2010 wasn’t wrong after all; just because the political consequences of admitting this might be harmful doesn’t make this false.
In sum, meh.
Even though it has been a year or more since the BoE published this paper, I still see it cited very often by bloggers, often in support of specific types of endogenous money theories. I think this paper is extremely informative, although I don’t think it is perfect, and I do think the authors sometimes extrapolate conclusions that aren’t necessarily warranted. In this post I intend to strip down the paper to its core elements, and analyze what implications (if any) they have for economic theory.
The paper begins by stating “Saving does not by itself increase the deposits or ‘funds available’ for banks to lend.”
This is true, at an individual level. If an individual purchases something instead of saving, this would have probably no net effect on the level of bank deposits. But what about the macro level? To an economist is the ‘savings’ rate of the public, by which I mean in this specific case (because it’s not usually defined as such) the amount of money the public hold as deposits at banks, decreased? No, the money leaves one deposit for another, so nothing changes. Essentially the problem is the authors seem to to be underestimating how abstractly economist are defining ‘savers’, since all deposits are classed as such, this implies purchasing something simply results in one person’s ‘savings’ reduced while another person’s (the seller’s) ‘savings’ increased, exactly offsetting the reduction. This is the case usually at least, given that most purchases are electronic, or at the very least, cash will eventually be deposited in a bank account. The only exception are people who store all of their money as cash under a mattress (mostly criminals), but they are negligible in the grand scheme of things.
The problem is that when economists say banks are intermediaries, they are talking about contrasting this with a world in which banks did not exist. If this was the case, the only money would be base money (cash), or near money substitutes. This would necessarily make it much harder for any firm to attain funds, if there was no institution to intermediate between lenders and borrowers, it would be extremely costly for an individual to lend; they’d likely need to hire a lawyer to draw up a contract, and they would have little diversification and ability to absorb losses meaning the risk premium would be much higher, this would result in very high interest rates and largely reduced lending in the economy.
Banks on the other hand are able to massively reduce the transactions costs, and absorb losses, when they lend. Reducing interest rates and massively increasing the availability of credit. Ultimately, base money is required for this, even though ‘broad’ money is created as new ‘demand deposits’ whenever a bank lends. So if banks were introduced into this economy, and people had the same level of comfortableness with depositing money at banks as they do today in reality, almost everyone would immediately convert their cash into a demand deposit at the bank, effectively making everyone a saver and lender under this technical definition. In which case, banks would hold a large amount of base money (which they might further still hold as reserves at the central bank), in the meantime banks would also be lending, and the amount of credit would be extended significantly in the economy. Add a monetary authority that can create more base money, and eventually you’d have something that looks mostly indistinguishable from the economy today.
So this result of vastly more lending when you contrast between a society without banks and only base money, and a society with banks, is what is emphasized when banks are described as intermediaries. Of course, the end result is that almost everyone is using broad money rather than base money, resulting in the base money held by banks to be more or less constant (unless changed by the central bank), causing this intermediary relationship to break down when considering broad money rather than base money (a transfer of one person’s broad money to another person’s account has no net effect on base money and the level of ‘saving’ as described above), it still remains true that an initial condition for this lending to have occurred is for the public to swap their base money for demand deposits (lending), in the first place.
This means that the statement: “saving does not by itself increase the deposits or ‘funds available’ for banks to lend”, in today’s economy, would not be surprising from any standard theoretical perspective, and it would be a mistake to label this as a misconception. This was a rather lengthy response to one sentence, but it’s a statement I keep hearing so I feel an urge to present my thoughts on this.
The paper then goes on to describe how it’s mistaken to believe that if the central bank changes the amount of base money, the amount of lending must increase with it. This is widely agreed to be false, and it does have implications for the idea of a money multiplier, at least the more simple concept that an increase in base money is always ‘multiplied’ by the banking sector by expanding credit until all excess reserves become desired reserves. I question, however, if any significant amount of people in academia believe in this simple model today, and whether this statement is really surprising.
Still, it does pose problems for any monetarist model that relies on increases in base money causing changes in aggregate demand, because it might rely on the assumption that an increase in base money causes an increase in broad money to move along with it.
What’s more important is that they note that the central bank does not “fix the amount of reserves that are available”. This is more pertinent, because this means the banking sector does not need to worry about finding more reserves if they wish to extend credit, in other words not only is there no current binding constraint on lending, but there is also no practical upper bound constraint on normal lending behavior imposed by the level of bank reserves (I say practical because this still relies on ongoing behaviour of the central bank, if you look at things ceteris paribus, where the central bank does not change the level of bank reserves, then reserves would indeed have an upper bound constraint, but this is not how central banks work in reality). This would call into question anyone who might say, for instance, that ‘while excess reserves don’t cause increased lending today, it does allow for banks to over expand the amount of lending they might do in the future, when the economy picks up again’. This would appear to be false, if the central bank will always increase reserves when the banking sector needs it, then current excess reserves would not affect the ability of banks to lend in the future.
This of course means that the central bank puts a constraint on the amount of lending in the economy using another instrument: interest rates. I think this is interesting, because it does challenge some endogenous money theorists who appear to act as if there is absolutely no exogenous constraint and that the central bank is completely irrelevant. This is not true, according to the bank of England; by controlling interest rates they necessarily affect lending decisions; if the rate of return on safe assets is high, banks will choose to charge higher interest on loans, which will result in less borrowing by the public, and ultimately less broad money being created.
Of course, this has little implication for modern macro models (New Keynesian DSGE), as they generally analyze changes in monetary policy as changes in interest rates, in which case this description of banking would not conflict with these models. They do however conflict with any monetarist who might consider a sudden increase in base money as expansionary ceteris paribus. Not that this seems to bother market monetarists, Nick Rowe for instance would emphasize various additional transmission mechanisms policies like Quantative-Easing could have to move demand, I remain less convinced.
Although speaking of QE, the paper does provide detail on this type of monetary policy and identifies a transmission mechanism. The first thing to note is that it immediately challenges the caricature of QE simply ‘giving money to bankers’. At least in the UK, with QE the central bank mainly purchases assets from the non bank private sector. Banks in this case are simply intermediaries between the central bank and the asset holder, they do gain a large amount of reserves in the process, but these reserves are an irrelevant by-product of the policy, and are matched by an accompanying liability by the former asset holder.
The paper instead describes the transmission mechanism thusly: “the central bank purchases a quantity of assets, financed by the creation of broad money and a corresponding increase in the amount of central bank reserves. The sellers of the assets will be left holding the newly created deposits in place of government bonds. They will be likely to be holding more money than they would like, relative to other assets that they wish to hold. They will therefore want to rebalance their portfolios, for example by using the new deposits to buy higher-yielding assets such as bonds and shares issued by companies — leading to the ‘hot potato’ effect discussed earlier. This will raise the value of those assets and lower the cost to companies of raising funds in these markets.”
This would again seem to challenge some endogenous money theorists who argue that QE has absolutely no effect whatsoever. The Bank of England is not on their side in this case. The central bank can create broad money after all, by purchasing directly from the non bank private sector. The portfolio re-balancing effect is a direct transmission mechanism that should in theory have an effect on aggregate demand. A mechanism that doesn’t rely on bank behaviour at all!
Still, don’t celebrate just yet monetarists. While this does increase broad money, it doesn’t have a substantial impact on an individuals actual net worth as they had to lose an asset of equal value in the process; people are made richer only to the extent that it increases asset values more than they otherwise would have been. Since the assets the central bank are legally allowed to buy are usually already fairly safe and liquid, the increase in their value (or decline in their yield) is mild, so the amount people are made richer by is also mild, which means I think the effect this policy has on AD is ultimately… well, mild. Mild compared to for instance a ‘helicopter drop’, which would be a no strings attached increase in the amount of broad money somebody holds.
So in summary, the implications for economic theory that the Bank of England’s stance on money creation has is as follows:
- It would appear to have no bearing on standard New Keynesian economic models, which analyze interest rates rather than changes in base money.
- It challenges the simple concept of a strict money multiplier, but nobody really uses that anymore.
- It challenges some monetarists who might have a less nuanced theory on the relationship between base money, broad money and demand, and who might expect that sudden increase in base money would have any substantial impact on bank behaviour, even if permanent.
- It challenges some endogenous money theorists who might claim that the central bank does not determine the amount of broad money at all, by identifying how it imposes limits on money creation by controlling interest rates.
- It might also challenge endogenous money theorists who claim that policies like QE have absolutely no effect in the UK, by identifying a transmission mechanism and emphasizing that assets are bought from the non-bank private sector.
- The identified transmission mechanism is not as strong as one that would involve a strict money multiplier on the newly created bank reserves.
All in all, I don’t expect this to substantially change anyone else’s stance on monetary policy, but anyone not familiar (if they still exist) with these concepts presented by the BoE would do well to acquaint themselves with them in order to save themselves from potential embarrassment.
Yes, I haven’t updated this blog in more than 2 years. Still, I thought I’d just post this for the record now before I forget forever. Back in 2013, Michael Woodford and Adair Turner proposed policies very similar to what I have proposed recently:
Particularly, this paragraph from Turner seems extremely similar to my own policy proposals:
“Under the Outright Monetary Financing approach that I propose, by contrast, the scale of money financed fiscal deficits would be clearly determined in advance by an independent central bank. The fiscal authority would decide how to spend the money (the balance between tax cuts and public expenditure): but the central bank would determine the amount of permanent money finance, consistent with an appropriate inflation or money GDP target. And it would do so as an independent central bank, and through the same decision making processes which govern the use of other monetary-policy tools.”
Likewise, in my post “Thinking the unthinkable – a proposal for demand management”, which was posted in the summer of 2012, I said:
“. Instead, a fully independent and non-partisan committee (like the FOMC, perhaps even the exact same people) should decide on a specific quantity of government spending that is to be financed by brand new money rather than by debt or by taxes … in accordance with some rule or target.”
I wonder, did Adair Turner somehow come across my extremely obscure blog at some point prior to 20th May 2013? 🙂
Sometimes I hear economists describe a nation as facing a soft budget constraint. It’s true, but it’s a funny choice of phrase because the literature on soft budget constraints initially was exploring how this caused monumental moral hazard and inefficiencies for firms in the soviet union and other centrally planned economies. This may have some slightly unpleasant implications for if the government explicitly acted as if the constraint they care about is inflation, at least it might under certain types of government self-financing. There is also a more interesting criticism, Daniel Kuehn contends “as James Macdonald argues, public debt has historically been an essential element in restraining government. Hoarded treasure (aside from being macroeconomically inefficient) ensures that sovereigns are unaccountable to their citizens. Citizen creditors ensure that their government stays accountable. Cutting out this debt instrument gives a sovereign all the revenue-raising power of government bonds, without any of the risk of nervous creditors restraining policy. Perhaps a robust republic can be maintained in such an environment, but if the Macdonald point is right, the chance of abuses are very real.” This is why many shudder when some MMT types appear to advocate an abolition of borrowing with politicians simply creating new money themselves directly in case they need more funds.
One good thing about my proposal, which I shall subsequently refer to as Rules Based New Money Financing of Government – RBNMFG (working title), is that it reconciles the moral hazard criticisms towards the ‘deficit owls’ with the demand sucking private debt fuelling criticisms towards the long-run budget constraint types. The committee in charge of RBNMFG is an agent of the government ensuring new money is issued consistent with a rule ensuring no output gad/no deficient demand and/or stable sectoral balances, in the same way that the judiciary is an agent of the government ensuring new laws are implemented consistent with legal precedent or a constitution. In this case the moral hazard problem is greatly diminished because there is a separation between the ‘print financing decision’ makers and the voter appeasing expenditure decision makers.
In sum we have two very useful insights:
(1) Monetary policy needs to be independent to prevent moral hazard and other problems (mainstream)
(2) Deficits might be needed for the foreseeable future to prevent the private sector going into deficit (MMT)
The MMT solution as explained in the first paragraph appeases (2) by violating (1). Mainstream solutions on the other hand might violate (2) in order to appease (1). I proposed the policy of ‘RBNMFG’ to appease both (1) and (2).
I think this illustrates pretty effectively the existence of sticky nominal wages in the US manufacturing sector.
In this post I am going to propose a counter-cyclical policy that I think should in principle find support from economists of many different schools, including post-Keynesian economists as well as market monetarists.
I believe that current monetary policy is convoluted and indirect, especially when interest rates are near zero. It operates through the banking sector, and the behaviour of banks is a highly nebulous and complex subject in which there is a lot of disagreement. It is also not understood well by the general public and some even find the current primary dealer system alarming. The transmission mechanism from unconventional policies like quantitative easing is contested, especially by those from the endogenous-money camp. While market monetarists have some highly complex inter-temporal hot potato, portfolio adjustment and signalling transmission mechanism, many have difficulty finding plausibility or potency in this story, and it goes far beyond conventional money quantity effects, hence my description of it as indirect.
What I propose is extremely simple and not especially novel (although almost as an unspoken rule very rarely discussed): monetary policy should bypass the banks. Instead, a fully independent and non-partisan committee (like the FOMC, perhaps even the exact same people) should decide on a specific quantity of government spending that is to be financed by brand new money rather than by debt or by taxes (before you tell me how insane, immoral, counterfeit or idiotic this is, please read my response to some of the criticisms at the bottom) in accordance with some rule or target. This would be done by adding new money to the treasury’s account at the central bank (for you ‘spend first’ or ‘keystrokes’ MMTists, see the criticism section below). This in principle should not find objection, I believe, from market monetarists; after-all, monetarist models do not depend on or have any specific role for bank behaviour (as people like Steve Keen like to point out), it is still at its core just adjusting the quantity of money.
On the other hand it is far more direct, there would no longer be endless debates about the transmission mechanism: government spending is widely dispersed and pays the salaries of people across the country and of all classes. This doesn’t inherently require or encourage statist or anti-market policies either, this new money could simply finance a reduction in sales tax for instance, which would have the added benefit of lowering supply side inflation to counter-act any demand side inflation created by quantity effects. It also does not relinquish traditional monetary policy, an increase in the quantity of new money supplied to the government would inherently decrease the amount of new bonds supplied, which in turn would lower their yield and vice versa for a reduction in new money: hence this new ‘expansionary’ or ‘contractionary’ monetary policy has the same effects as before on interest rates. And even if it doesn’t, I see no reason traditional open market operations could not be conducted in addition to this policy.
Another benefit of this policy is that an increase in the money supply isn’t inherently caused by an increase in credit, thus discussion about unsustainable credit booms or fiat ponzi schemes where credit must be extended forever to pay-off the interest of the old credit would be greatly diminished. This would also be enormously helpful to those who worry about high household debt, this new money could be used to finance principal reductions and all kinds of other policies aimed at reducing indebtedness.
This is also entirely consistent with the rules based proposals advocated by Scott Sumner; the aspect of market monetarism that has much more bipartisan support (Michael Sankowski of the Monetary Realist camp for instance has said he is in favour of NGDP targeting). The quantity of new money, as before, could be set in accordance with a path for the inflation level or nominal gross domestic product growth. This time however there would be no doubt as to whether the target could be met or not, which is why I really think its something market monetarists should support.
Of course, one criticism I would expect to see, especially from monetarists, is that this policy is too radical and unnecessary, ‘we don’t need to change the demand management system since the current system is fine for that’. On the contrary, as I explained before I think monetary policy is highly convoluted and I would argue not optimal; Occam’s razor, I believe, would favour my proposal instead, which is far more simple in not relying on bank behaviour or credit, in essence changing policy structure such that it actually behaves more closely to monetarist models.
Now let me explain what this isn’t. This is not ‘printing our way to prosperity’, this is purely increasing demand, it is not a supply side policy. I agree with people like Cullen Roche and really most economists in that long run growth relies entirely on productivity and innovation (I would add institutional quality to that as well), not the quantity of money. This policy is not aimed at making us all more productive, instead it is merely a policy aimed at stabilising fluctuations in demand.
Of course there are serious criticisms that could be levied at this proposal, it is not perfect, I will analyse a few here:
People have non-linear, unpredictable or volatile demand for money (hyperinflation): This argument, favoured by Austrians, is that a policy like this would remove any ambiguity about what modern money really is (i.e. ‘nothing’, ‘toilet paper’, ‘not backed by anything’), and thus people, rationally or irrationally, will reject the currency, leading to hyperinflation which cannot be controlled merely by adjusting the quantity of money. While I can sympathise with this argument, it’s really not clear that this is actually the case. According to Bill Mitchell, the demand for money is not as simple as conventional wisdom suggests, fiat money still has utility for people because it can, for instance, extinguish tax liabilities. Others, like John Kay or Cullen Roche emphasize money as a social convention, useful in as much as other people also find it useful. Furthermore, I don’t think it is unclear to people what modern money really is regardless. Any statistics of M2 or the monetary base will show you that money has increased massively without being backed by anything and without causing hyperinflation. Suffice to say, I find the idea of people spontaneously rejecting the dollar, or the pound, not very plausible.
Moral hazard: perhaps a stronger argument, also favoured by Austrians. The government could easily get addicted to this free money, and this soft budget constraint (of which there is a large and interesting literature, useful for analysing centrally planned economies and their failures) would cause the government to become progressively more inefficient due to the incentive to cut down on wasteful costs becoming more and more diminished. This argument is a persuasive and important one, however I’m not sure if my policy would actually change anything, as Cullen Roche shows: the way treasury auctions are set up with primary dealers in countries which are sovereign in their currency (as opposed to say Euro-zone countries) makes the idea that the government would ever have much trouble finding funds or would have to suffer high interest rates due to investor risk premiums nearly impossible. In this case, there is already moral hazard and I don’t see how my policy has changed anything. You could argue that high quantities of debt in themselves are simply scary, which might put off government spending too much money, but it seems pretty clear to me in the face of ever increasing public debt that governments, despite their rhetoric, don’t really care that much.
Unnecessary, government spending is just key-strokes, they don’t have to worry about how much money is in their account: this would be from MMTists. First, I agree that the only thing preventing the government behaving in this way is self-imposed legal constraints. On the other hand, procuring funds is how governments today actually work, as Cullen Roche, former MMTer who started his own school after finding MMT too detached from the real world (ironically) explains:
“More recently, MMTers have started using two conflicting descriptions of monetary options. They now use a “general case” and a “specific” case to explain why the government “spends first” in their general case and actually procures funds first in the specific case. This is an evolution in MMT ideas that obscures and hides the fact that MMT’s long-held positions on “operational realities” are in fact shifting and/or misleading….
…To argue that the government does not procure funds to spend is a semantic debate because the government must always procure funds to ensure that the private sector allows the government to deal in the social construct (money) of the people (government of course being a construct of the people inherently making money a creature of the people and not just the state as MMT says)…”
It is also in our interests to make sure new outside money is created by an impartial and non partisan or perhaps rules based process, rather than entirely subject to the whims of short term thinking politicians, I hope I can find some agreement with MMT there.
Demand is not deficient, we are always at full employment: used by some RBCists and Austrians. While I disagree, obviously, this simply suggests that we should never need to manage demand, it doesn’t suggest that this would be a bad policy at doing so should we need to.
In sum, I believe this policy to be simple with very few complications (far less compared to current demand management policy), no doubts about its effectiveness at what it does (increasing/decreasing demand, with no pretense about it increasing productivity or long run potential growth), and that suffers from criticisms which I believe are not strong enough to shoot this policy down.
Update: one more issue I forgot to address
Infrequency of budget decisions: this is something market monetarists are also likely to raise as a criticism, pointing to the advantages central banks have in being able to react more immediately to changing conditions. The remedy is simple, every quarter the committee can announce a quantity of money it projects will need to be provided for public expenditure during the next fiscal year, until private sector forecasts of NGDP or inflation (for instance) for that year are on track, which in turn is likely to affect growth in the current year by altering expectations. As market monetarists say, much of monetary policy is essentially signalling and expectations.
Even then, it is possible that some tax decisions could be decided quarterly instead of annually, although depending on the tax this could create some uncertainty. You could also set up independently financed government institutions, such as public investment banks, that could receive government support decided on a quarterly basis. I’m sure we could find plenty of schemes with quarterly or semi-annual expenditure decisions should expectations not be enough, so I don’t find that criticism too worrisome.
Steve Randy Waldman, in an email, expressing support for the idea points out that this policy shares some similarities with his own and Haito Zhang’s policy proposals, in that “they share with your proposal a preference for fiscal spending or “helicopter money” rather than bank-mediated leverage as a macro policy instrument.” Steve’s proposal is even more radical than mine, not only bypassing banks but the government too, directly depositing money to individual bank accounts (with perhaps some lottery mechanism to prevent moral hazard), while Haito’s is an interesting democratised fiscal expenditure/investment program combined with an NGDP target although is not too specific on the financing. Getting political support for a proposal like mine would be extremely hard, but I think Steve’s proposal would probably be even harder. I’d argue that Hatio’s & Steve’ s solution are unnecessary while my proposal is simpler and logistically easier to administer, but they are interesting and innovative approaches none the less.
Ninety-Nine percent of the time, when people criticise ‘mainstream’ economics, they are in fact criticising neoclassical economics. I recently came across a paper titled “The turn in economics: neoclassical dominance to mainstream pluralism?” published in the Journal of Institutional Economics, which investigates the question ” why neoclassical economics no longer dominates mainstream economics.” Note that this paper was written in 2006, before the financial crisis. The paper attempts to explain trends in economic research over the last two decades including fields such as “game theory, experimental economics, behavioral economics, evolutionary economics, neuroeconomics, and non-linear complexity theory” and explores a few possible theories as to why neoclassical economics may no longer dominate the mainstream, concluding that “non-neoclassical development at the economics research frontier provides evidence that neoclassical dominance of economics is being supplanted by a new mainstream pluralism.” If you’re interested in this sort of stuff, I recommend you take a look at the paper, although I should warn you that it is a bit of a dry read.
In general I’d agree with the conclusion, at least with regards to the research frontier. A large chunk of modern economics does not resemble the caricatures of conventional neoclassical economics at all. First of all, I’d argue a huge amount of economics is largely just empirical work, much of it using minimal assumptions or just completely atheoretical in general. The state of empirical economics in most sub-fields is actually very good [pdf]. As for macroeconomics, while the empirical quality of new papers has not quite caught up with its microeconometric or experimental counterparts, recent trends in VAR modelling has seen a resurgence in macroeconometrics which is not bogged down in too many assumptions.
And on the theory side as well there are many trends which depart from the simplistic stereotype of neoclassical economics. Even considering models with strictly rational behaviour, modern micro almost entirely consists now of evaluating things like information asymmetry (which implies bounded rationality), moral hazard and adverse selection, giving very plausible insights as to how markets or institutions may fail even in ideal situations which would surely be invaluable to many policy makers. Further still, the literature on behavioural economics or other deviations from stricly rational markets has exploded as Chris Dillow notes, with books from Nobel prize winning economists like Animal Spirits receiving much acclaim from their colleagues.
As for instruction, I certainly agree that undergraduate core textbooks could do with a clean-up. But I think students gain most of their insights from optional/supplementary modules or from additional material given to students by their professors, in this regard core macro or micro textbooks are anything but a comprehensive coverage of economics education. In my MSc course, for instance, the most popular courses students attended were modules such as experimental economics, micro-econometrics, economic history and developmental economics. It is perfectly possible, and in fact quite likely, that the majority of classes a 4th/post-graduate MSc student will take are not neoclassical in nature, at least in my university.
