Deficit myths (Part 3): The effect of budget deficits on business profits

Martin Wolf is right in saying that government fiscal tightening will hurt business profits. As Wolf correctly points out: "In order to reduce huge government deficits, surpluses must fall elsewhere".

For the UK, this means that the only way the government can succeed in balancing its budget is if the reduction in the government deficit is offset by a reduction of equivalent magnitude in the surplus of at least one other sector of the economy (i.e. household, corporate or foreign sector). And according to Wolf, the surplus sector that is most likely to be affected by the government's plan to reduce the deficit is the corporate sector because, at the moment, the household sector is not willing to incur additional debt (and fall back into deficit) and UK exporters are unlikely to reverse the flow of wealth currently exiting the UK economy (thereby reducing the surplus of foreigners).*

In a way, Wolf could just easily have argued that, in the UK right now, it is the government deficit that is enabling the corporate sector to run a surplus. And when households are deleveraging and exports are declining, business profits can only be realized if the government runs a deficit. Thus, by cutting the deficit, the government is in effect reducing an important source of business profits.

Proof of this direct, positive relationship between government deficits and business profits is best demonstrated by manipulating the basic national income accounting identity in a manner consistent with the approach of economists John Maynard Keynes and Michal Kalecki. The following arithmetic demonstrates that government deficits have a positive effect on business profits.

Let Y=Total Output; C=Consumption; I=Investment; G=Government Expenditures; X=Exports; M=Imports; T=Taxes; R=Retained Earnings by Firms; Hs=Household Net Savings

Let the combination of the above (X - M) = Current Account Balance or Net Exports; (G - T) = Government Deficit; (Hs + R) = (Y - T - C) = Total Net Private Savings

To start off, here is the basic national income identity, as taught in all macroeconomic textbooks:
Y = C + I + G + (X - M)

Subtract taxes (from both sides of the equation) to achieve an equation "net" of taxes:
Y - T = C + I + G + (X - M) - T

Rearrange the equation to isolate total net private savings on the left side and to subtract taxes from government expenditures:
Y - T - C = I + (G - T) + (X - M)

Since (Y - T - C) can be broken down into household net savings (Hs) and retained earnings by firms (R), the equation can be stated as follows (see Krugman, 1994:313):
(Hs + R) = I + (G + T) + (X - M) 

...and can be rearranged as such:
R = (I - Hs) + (G - T) + (X - M)

In plain English, this translates into:
Firms' Retained Earnings = Investment - Household Savings + Government Deficits + Net Exports

The above equation clearly demonstrates that business profits are positively impacted by government deficits, net exports and private sector investment.* Household net savings, on the other hand, have the effect of reducing firms' retained earnings. Similarly, balanced budgets and government surpluses have either no impact on profits or have the effect of reducing them.

One objection to this line of reasoning often invoked by economists is that government deficits increase the level of private sector savings (as households and businesses reduce consumption in anticipation of future tax increases). This claim is known as the Ricardian Equivalence proposition. However, there is little empirical evidence that this claim holds true and that the impact of government deficits gets neutralized (or offset) by a corresponding increase in private sector savings. As Douglas Bernheim argued in his seminal work on the topic:
...the case for long-run neutrality is extremely weak, in that it depends upon improbable assumptions that are either directly or indirectly falsified through empirical observation...[B]ehavioral evidence weighs heavily against the Ricardian view (1987:213)
To conclude, it should be emphasized that the purpose of economic policy is not to enable firms to realize profits, but to maximize employment and ensure that the product of industry is beneficial to the overall economy. Business profits, by creating an incentive for firms to invest and employ available resources, can help to promote these objectives. In the above analysis, my aim is to show that government deficits cannot be looked at in isolation from the financial positions of other sectors of the economy. Whether it is to stabilize aggregate demand or to provide for much needed public goods, deficits serve an important purpose. Attempting to reduce government deficits without considering its impact on the overall economy is not a sound basis for policy.

  1. Nice post.

    The Ricardian Equivalence is closely related to the postulate in economic models which more or less says that the economic agent is able to see his future perfectly.

    In this future, the agent sees the government taxing more to get back the spending outflow and the agent decides to save more!

    Charles Goodhart pointed to a similar assumption about the creation of the Euro Area.

    "The first, and most important, incorrect assumption was that a private-sector deficit in any country, matched by a capital inflow (current account deficit), should not be potentially destabilising. The thinking was that the private sector must have worked out how to repay its debts before incurring them."

  2. Circuit, one must assume that Martin Wolf

    (http://www.theglobeandmail.com/report-on-business/international-news/global-exchange/financial-times/why-cutting-fiscal-deficits-is-an-assault-on-profits/article2249143/?utm_medium=Feeds%3A%20RSS%2FAtom&utm_source=Home&utm_content=2249143)

    reads or has read FRB.

    His analysis of the UK policy is underlined by the same arguments that pervaded your excellent March 23, 2011 article

    (http://fictionalbarking.blogspot.com/2011/03/canadas-federal-budget-note-on-tax-cuts.html).

    If the similarity is a coincidence, then coincidence of this form is a reflection of remarkable insight. It's good setting that there be a Watch like Wolf and Fictional Reserve Barking highlighting the nonsense that is being professed by shortsighted leaderships, especially in Europe.

    Nods to both of you!

  3. Thanks Ramanan. The paper you link is an excellent piece. The assumption you point to was a key EMU intellectual underpinning.

    Nod KP - Wolf's approach is similar to my May 21 entry on Canada's corporate surplus. His was a very good article. I read some of the reader comments; most readers didn't seem to get the point at all. They appear to think that he's being apologetic to the corporates! I sure hope Cameron's advisers get the message.

  4. steve keen can take a lesson on how to simplify debunking by reading this post. very nice.

  5. I concur with Ram (whom I commend for his insights on many sites) and JH on Steve Keen. He has a tendency to be verbose to the point of becoming a straussian. Keen often complicates and that usually alienates.

    Circuit you wrote a fine piece. It's important these days to focus on policy design and implementation as most of the 'five' emphasize. When someone decides to introduce paradigmatic action, it is critical that legislators understand it and essential that someone can communicate it properly to the public and configure it effectively within the institutional norms of the various authorities. Your overall presentations and analyses not only simplify understanding the gauge, but they warrant an appreciation of how circuit theory efficiently inserts itself within the conceptual framework of conventional economic policy and global economic activities.

    It is messy, not to say amateurish, in the blogsphere (forget the blogosphere-who the h...coined that adjunct)and there is more 'rubbish' and 'raucus' being processed than policy pragmatists care for.

    Hold the course on the modus vivendi and operandi- keep the exposes simple as you so excellently did. Stay away from the 'raucus'. One of the inspiring facets of Godley's work is that he kept it so simple!!!

  6. Indeed, Ramanan raises interesting points. He has a good grasp of post-Keynesianism and has a knack for citing statutes and policies relevant to fiscal and monetary policy. Makes for interesting exchanges.

    JH, Swells, I'm glad you appreciate the format and agree that my blend of circuitry and mainstream analysis has value. I have to agree that presentation is important. It definitely helps to carry the message. Also, I should say I appreciate your comments. Some of my colleagues told me offline they appreciate the added insight and historical perspective. The discussions on Volcker, LBJ and Keynes were particularly well-regarded. As for Godley, what can I say? I'm not one to think people are very good at forecasting and predicting the future. But Godley...what talent. Nod to him and everyone who's adopted his approach.

  7. Les trois rubriques sur 'Deficits Myths' sont formidables. Une chose certaine, y'a une gang qui vous suit a UQAM, et on trouve pas du 'chattering' sur FRB. J'aime bien l'acronyme FRB, je pense toujours, par defaut, a FDR...aucune logique (maybe).


    A+
