It is Wednesday and so a shorter blog post today while I spend more time writing other things. But there was one issue that was raised in the comments in the last week following my blog post – Build it in Britain is just sensible logic (July 26, 2018) – that I thought warranted attention. The government is not a household is a core Modern Monetary Theory (MMT) proposition because it separates the currency issuer from the currency user and allows us to appreciate the constraints that each has on its spending capacities. In the case of a household, there are both real and financial resource constraints which limit its spending and necessitate strategies being put in place to facilitate that spending (getting income, running down savings, borrowing, selling assets). In the case of a currency-issuing government the only constraints beyond the political are the available real resource that are for sale in that currency. Beyond that, the government sector thus assumes broad responsibilities as the currency issuer, which are not necessarily borne by individual consumers. Its objectives are different. Which brings trade into the picture. Another core MMT proposition is that imports are a benefit and exports are a cost. So why would I support Jeremy Corbyn’s Build it in Britain policy, which is really an import competing strategy? Simple, the government is not a household.
