Under a job guarantee, there would be a standing job offer at a living wage for anyone who wanted such a position. Anyone without employment in the broader economy, or unhappy with their present employment, could opt for a position in the job-guarantee program. Similarly, individuals with less hours of employment than desired could top up their hours by working part-time in the job-guarantee program. In principle, the program might be locally or centrally administered. But, irrespective of administrative details, it will be assumed that a currency-issuing government funds the program.
What is the most appropriate entry point to the study of a monetary economy in which government is currency issuer? Is it “the market”? Is it the definition: total spending equals total income? Is it real exchange? Real production? Is it total output? Total employment? Total value? Distribution of income? The origin of profit? Price formation? Competition?
Saul (real name Jackson Daly) stood amid general hilarity by the lake, drenched in moonlight and old and tawny port, a bottle of which he clutched to his chest. It had been procured earlier that day from the one and only liquor store in the small New South Wales coastal town of Sunshine. A scattering of his brothers and sisters, sprawled on a grassy knoll, partook of wine and herbal cigarettes. They looked at him expectantly, as though he might have something important to say, but he backed away, without comment, and headed toward the road. It traced the edge of the lake and could have led Saul, if he’d wished, all the way to the pier.
Some days, when things seem quiet on the economic front, and even occasionally when they don’t, minds can wander to less weighty matters and become momentarily lost in daydreams of yesteryear; a heady retreat, for instance, back to high school math class one barmy afternoon, sunshine streaming through the windows facing on to Main Quad, with the keener students engrossed in an exploration of the wonders of polynomials; back to a delirious springtime trance interrupted, rudely, by one of the less enthralled students, who wondered aloud, “Yeah, but what good are they in the real world?”
A monetarily sovereign government is one that issues its own currency and is the currency’s sole issuer. Ideally, it allows the currency’s value to float in relation to other currencies in foreign exchange markets, meaning its currency is not convertible at a fixed rate into either another currency or a commodity (other than possibly the commodity labor-power through the provision of a job guarantee). Although this ideal maximizes policy space, a government that promises convertibility can renege at a later date, and so, strictly speaking, does not relinquish its monetary sovereignty so long as it retains the authority to issue its own currency. A monetarily sovereign government that operates a flexible exchange rate faces no revenue constraint provided it refrains from borrowing in a foreign currency and so avoids exchange-rate risk on its debt.
It is easy to represent the ‘income-expenditure model’ in a graph. Some people find this helpful as a visual aid to understanding; others, not so much. For those who find graphs confusing, this post can safely be ignored. In terms of economic meaning, it does not add much to what has already been explained. But for those who are comfortable with graphs, they can be a handy tool for illustrating or thinking through the logic of a model.
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.
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.
At the macro level, equilibrium requires that total demand in product markets equals total supply. This could occur at high or low levels of output and employment. Equilibrium implies stable output, but it does not ensure full employment.
