Why Chickens?The origin of this article was the following tweet by David Andolfatto.*
Since he is working within a 280 character limit, the risk is that we read too much into this. Although I disagree with the sentiments (for reasons to be discussed), I think the point can be understood using mainstream economic assumptions.I'm sorry, but this is just wrong. Govt wants your chicken and takes your chicken--you're down a chicken. Govt says it wants your $, makes you sell your chicken to govt for $. You're still down a chicken. What's the difference? https://t.co/Ndt2ubcRI7— David Andolfatto (@dandolfa) April 24, 2019
If we go beyond what is embedded in the 280 characters, we can see how the mainstream assumptions differ from MMT.
Basic AnalysisAndolfatto is correct when he points out that there is no difference from the perspective of the household. But even then, he has embedded a new version of a barter-based double coincidence: the government wants your chicken, and you coincidentally have one.
Since even American citizens are unlikely to possess aircraft carriers (yet), the government cannot rely on this double coincidence to occur. Furthermore, how can it get people to enforce laws and so forth? Force community service on lawyers so that they take turns to enforce the law? (There is one case where governments have successfully provisioned themselves in kind -- drafting young men into the military. This works, since they just need bodies to act as cannon fodder.)
|How many chickens is this guy worth?|
Imagine a Canadian tax collector showed up at my door and demanded a live chicken**. The only live animal I could offer is one of my cats (pictured on the left). The question is: what is the exchange rate between cute fuzzy cats and chickens? Since we do not live in a world where there is a magical general equilibrium exchange ratio between all goods, there is no obvious way to determine whether the tax obligation has been discharged. The use of a monetary unit of account ends such uncertainty.
(This demonstrates a key difference between voluntary transactions, and legal obligations -- taxes, debts. For a voluntary transaction, if your counterparty does not use a reasonable valuation -- "off market" -- you just find a different counterparty. The need for market makers to be "on market" means that we can typically infer an arbitrage-free pricing "curves" in fixed income and derivatives (except when markets are totally disjointed). However, the need to discharge an obligation forces both parties to agree on the valuation (or acceptability of deliverability of goods into a contract). This explains why financial analysis can get away with equilibrium concepts, whereas equilibrium is dangerous in economic analysis.)
Thus, the superficial analysis shows that there are massive practical differences between taxes imposed in the monetary unit of account versus payment-in-kind. However, there are deeper theoretical issues, which are discussed next.
Theoretical PointsThe real question of interest: is it safe to argue that neoclassical models -- particularly those that are given in terms of real goods -- already cover the MMT argument that real resources matter for the analysis of fiscal policy?
The Andolfatto quote matches some fairly standard assumptions of neoclassical analysis.
- Household-centric. The discussion of taxes is in terms of how it effects a household, in particular, it's utility. Is this really the correct frame when discussing government policy? If the objective is to defeat some menace, stomping on some households' utility is the least of the government's concerns.
- Composite good. The assumption that a household would have a live chicken on hand is what you would expect if you always work with composite goods. That is, a household has a standard consumption basket, and so taxes are in essence reducing the size of the basket that can be bought. However, this is not helpful if the government wants to achieve particular goals -- e.g., replace carbon-based energy sources in the economy (a.k.a., the Green New Deal). The availability of particular inputs cannot be taken for granted.
- Taxes almost never are matched to the producers of desired goods. Many specialised goods and services the government wants to purchase cannot be bought on existing markets: artillery, bridges, road repair, etc. If the government does not produce the desired output itself, it needs to induce the private sector to develop the specialised skills to produce the output. That is, if the government just seized tanks, nobody would go into the business of producing tanks -- since they would be just seized, and cannot legally be sold into the market.
This means that standard neoclassical theory is not particularly helpful. If the economy just had a single good (composite or not), the economic calculation problem would be rather trivial. That is, the economy could easily be centrally planned, and optimal outcomes obtained. The reality is the multiplicity of goods makes central planning difficult (although the abandonment of anti-trust laws means that some conglomerates are entering the central planning business).
However, there are circumstances where these assumptions are not too far off. This is the case when the government attempts to have no distinctive economic footprint in the economy. Essentially, this is what neoliberalism is all about.
If the government expenditures are just used to buy standard goods in the markets, hire staff, and make transfers, there are no specific goods the government worries about. They may purchase office equipment, but that would just be a standard consumption basket. And government wages and transfers are just going back to the household sector, which is then presumably used to purchase the household consumption basket.
In which case, the effect of fiscal policy is just to take some workers out of the labour market, and provide demand for goods in standard consumption baskets. In which case, an aggregated approach should provide a decent approximation of reality.
We can probably get away with ignoring the real effects of fiscal policy if we constrain governments from doing anything other than creating demand for standard consumption baskets. Moving in that direction has certainly been the thrust of post-1980 policy. However, that is a political choice, and there is no reason to believe that governments will always have that luxury.

** David Andolfatto verified that the "chicken" in the tweet was in fact a live chicken.

I don't think you want to leave your readers with the idea that taxes don't matter. From my experience on the supply side of the economy , taxes are built into the cost of every project at the point of initial go/no-go decision. The goal of the supply side decision maker will be to first recover cost and secondly to make a profit.ReplyDelete
Tax effects really come to the front when considering small producers who primarily are selling their own time by building or maintaining a product. To the extent that government "takes their chicken" or, maybe more importantly, dictates the conditions and quality of exchange, government is strongly influencing their decision on how to utilize their personal work time. The worst result an economy can endure is when talented workers limit their efforts to only caring for themselves.
Where did I write that taxes don’t matter? I just explained why they are imposed in terms of money.Delete
Just to follow up a little, it makes no sense to seek live chickens from government workers. They obviously would not have such a thing.ReplyDelete
The same principal extends to the question of whether we can expect government workers to pay taxes? Not only do government workers not have chickens, they do not have money that can be used to pay taxes. That statement follows recognition that government workers are paid with money from taxes in the first place.
Now we can ask about government workers paid with borrowed funds. I guess the same conditions would apply here.
Yes, indeed, taxes do matter in an economy.
