Bill Mitchell quotes five Republican Senators in the US Congress as proclaiming it is: “the duty of the Senate to condemn Modern Monetary Theory and recognizing that the implementation of Modern Monetary Theory would lead to higher deficits and higher inflation”.
Science is something quite different from politics and senators have NOTHING AT ALL to say in the realm of science. People forget this because they have come to think that political blather, talk show, and scientific debate is essentially the same thing. This is partially the fault of economists themselves, who for the greater part lack a proper understanding of what science is all about.
Economic discussions suffer from the fact that both microfoundations and macrofoundations are provably false. The major approaches ― Walrasianism, Keynesianism, Marxianism, Austrianism, MMT ― are materially/formally inconsistent and mutually contradictory. This is why all economic discussions end in the bottomless swamp of cross-talk, interpretation, exegesis, second-guessing, and “what x REALLY meant” but for some mysterious reason could not clearly express.
To get out of the proto-scientific swamp requires a Paradigm Shift, i.e. the move from false Walrasian microfoundations and false Keynesian macrofoundations to true macrofoundations.#1
From the true macrofoundations follows the macroeconomic Law of Supply and Demand as shown on Wikimedia.#2 It says in the elementary case:
(ii) Deficit spending, i.e. the move from ρE=1 to ρE >1 causes a one-off price hike but NOT inflation† if the deficit spending is exactly repeated period after period.#3, #4, #5, #6 A steadily rising public debt is compatible with price stability after the first hike. Only successively INCREASING budget deficits produce continuous price increases.
(iii) An increase in the ratio of wage rate to productivity W/R leads to a higher market clearing price P. If this is repeated period after period one gets inflation depending on the rates of change of W and R in each successive period.
Roughly speaking, the macroeconomic Law of Supply and Demand explains the price level in the elementary production-consumption economy and its development over time. The equation contains but measurable variables and is therefore testable in principle.
The relationship between the average amount of fiat money M and the expenditure ratio ρE, the wage rate W and employment L is shown on Wikimedia.#7
Conclusion: The MMT policy of deficit-spending/money-creation causes a one-off price hike but NOT inflation. The lethal effect of MMT policy is on distribution.#8, #9, #10 The Weimar/Zimbabwe/Inflation shouters suffer from incurable idiocy and cannot be admitted to a serious economic discussion. The fact is that MMT policy does NOT produce inflation but, according to the macroeconomic Profit Law Public Deficit = Private Profit, the Oligarchy’s financial wealth (currently about $22 trillion and counting). This public debt is the own handiwork of nobody else than the US Congress and all worked just fine without inflation.
† "In economics, inflation refers to a general progressive increase in prices of goods and services in an economy." (Wikipedia) A price hike refers to one period, inflation means successive price hikes over two or more periods with the rates of price changes being equal or increasing. Strictly speaking, the minimum length of inflation is two periods. The standard period length is the calendar year.
For a start X=O, i.e. market-clearing holds. The ratio ρE≡EC/Yw is called expenditure ratio; ρE=1 indicates budget-balancing of the household sector.
