Short & Simple 19 – Sectoral Balances in a Closed, Demand-Determined Economy

We have seen that the ‘income-expenditure model’ combines key macro identities (introduced in parts 7 and 15) with particular behavioral assumptions to provide a theory of income determination (considered in parts 16 and 18). The behavioral assumptions relate to causation. The causation envisaged in the income-expenditure model has implications for the sectoral balances, some of which are the focus of the present post.

The Social Economy and the Potential Inherent in Currency Sovereignty

In any society, of whatever configuration, production at a given point in time is limited by certain ‘real’ (meaning non-monetary) factors. Notably, a society’s productive activity will always be limited by access to natural resources, the current state of its technology, and the skill, strength, size and imagination of its people. These and similar factors determine the absolute productive potential of a society. At a given point in time, these factors would apply even if, hypothetically, a society happened to be organized in a completely different way to its current form of existence.

Short & Simple 13 – Private Credit Creation

We have seen that a national currency enters the economy when government spends, and that the recipients of the government spending can use the currency for various purposes, including to purchase goods and services. Government is therefore an original source of funds.

There is another original source of funds that gives people the ability to make purchases. This other source is private credit creation. Put simply, a household or firm can borrow from a bank or other financial institution and use the funds to spend.

Short & Simple 12 – Government Money

We saw in part 2 that to establish a currency, government needs to do three things:

1. Define a unit of account (e.g. dollar).
2. Impose taxes that can only be paid in that unit of account.
3. Spend or lend the currency into existence.

The most basic purpose of taxation (introduced in step 2 of the sequence) is to create a demand for the currency. Provided taxes are effectively enforced, we in the non-government will have a need to obtain the currency, because it is the only means of paying taxes.

Professor Bill Mitchell in New Zealand Discussing MMT

This is a presentation by Professor Bill Mitchell at the University of Victoria, Wellington, New Zealand on July 28, 2017. It addresses framing of the macroeconomic policy debate and touches on the most fundamental insights of Modern Monetary Theory. Most here will be avid readers of the professor’s blog, but this talk is too good not to post. While in New Zealand, Professor Mitchell also did an interview for the public broadcaster. A link can be found in the billy blog post of July 31, 2017.
