A recent post considered one way of including a job guarantee in the income-expenditure model. Doing so makes it possible to represent various macro effects of a job guarantee within the model. An obvious effect is that the program would deliver a degree of demand stabilization. An effect that is perhaps not quite so obvious is the way in which a job guarantee would ensure supply-side changes in the economy automatically impact on demand, actual output and employment. Before illustrating a few of these effects, the modified income-expenditure model will be briefly outlined and tailored to present purposes. A fuller discussion of the model is provided in the earlier post.
