It is well known that for Keynes the demand for investment goods, as for labor services, is a derived demand. The demand for investment goods ultimately depends on the extent to which they are needed to produce items of consumption. Certainly, one investment good may be required in the production of a second investment good which, in turn, is needed to produce the first investment good. Iron gets sold to steelmakers who sell some steel to iron makers in a circle that never makes direct contact with the production of consumption goods. But this occurs because such maintenance of iron and steel works enables, indirectly, the supply of investment goods for the production of items of consumption.
The notion of tax-driven money is easiest to understand in relation to an exogenous tax such as a property tax or simple head tax. Demand for a state money is most effectively driven by exogenous taxes, not endogenous ones such as income taxes. Even so, in a hypothetical system with a tax imposed solely on income, the tax would still drive demand for a state money. It is worth considering why this is the case, because it also indicates why some level (though not absolutely any level) of basic income would also be consistent with currency viability.
This is a follow-up to a recent post on the income-expenditure (IE) model and is at a similar introductory level. Some knowledge from the previous post is assumed, so for those unfamiliar with the model, it would be best to read that post before this one. The purpose is to explain how the model can be represented graphically in a two-panel diagram. The top panel shows equilibrium and disequilibrium adjustments in terms of income and planned expenditure. The bottom panel shows them in terms of planned leakages and injections.
Warren Mosler’s contributions to the MMT Round Table in Sofia required a translator for the Bulgarian audience. As an alternative to watching the videos (which can be viewed in video 1 and video 2), some might find it convenient to read transcripts of his talk and Q&A session. Repetitions of phrases due to the translation process have been edited out, and a word or two not deciphered, but apart from that the transcripts are as spoken. In the talk, Warren briefly discusses Professor Hanke’s view of the currency board before explaining: (i) the basics of establishing a sovereign currency; (ii) determinants of the value of the currency; and (iii) the dynamics of the currency board. In the Q&A session, he discusses what would be involved in getting off the currency board and reviving the economy, making comparisons with Argentina’s experience under similar circumstances. As always, Warren speaks with great clarity. Unfortunately I am unable to transcribe the talks by Pavlina Tcherneva and Ryan Markov due to the language barrier.
