Government Financial System Could Make Private One Work Better
One of the most basic functions of a financial system is that it allows people to smooth their consumption spending over time. The oldest example of this is probably when Joseph advised the Pharaoh to store the surplus from Egypt's bumper crops in the expectation of future famine. Since then, private firms have developed a range of products to help households and businesses weather the vicissitudes of life. Unfortunately, some of these products don't perform as advertised, which can cause extreme hardship and amplify economic cycles.
Fortunately, governments with their own currencies can offer many useful financial products at lower costs than traditional banks, insurers and asset managers. This is because, unlike other borrowers, governments never have to worry about running out of money. For better and for worse, they can always print what they need. While we already take advantage of this to some extent, we could do it even more.
