One of the most highly debated topics over the past few months has been the rise of Modern Monetary Theory (MMT). The economic theory has been around for quite some time but was shoved into prominence recently by Congressional Representative Alexandria Ocasio-Cortez’s “New Green Deal” which is heavily dependent on massive levels of Government funding.
There is much debate on both sides of the argument but, as is the case with all economic theories, supporters tend to latch onto the ideas they like, ignore the parts they don’t, and aggressively attack those who disagree with them. However, what we should all want is a robust set of fiscal and monetary policies which drive long-term economic prosperity for all.
Here is the problem with all economic theories – they sound great in theory, but in practice, it has been a vastly different outcome. For example, when it comes to deficits, John Maynard Keynes contended that:
“A general glut would occur when aggregate demand for goods was insufficient, leading to an economic downturn resulting in losses of potential output due to unnecessarily high unemployment, which results from the defensive (or reactive) decisions of the producers.”
In other words, when there is a lack of demand from consumers due to high unemployment, then the contraction in demand would force producers to take defensive actions to reduce output. Such a confluence of actions would lead to a recession.
In such a situation, Keynesian economics states that government policies could be used to increase aggregate demand, thus increasing economic activity and reducing unemployment and deflation. Investment by government injects income, which results in more spending in the general economy, which in turn stimulates more production and investment involving still more income and spending and so forth.The initial stimulation starts a cascade of events, whose total increase in economic activity is a multiple of the original investment.
