In microeconomics, \$USD are a store of value. I can sell a candy bar for \$1, and I can hang onto that \$1 for a year and then buy the same candy bar for that same \$1. If I print \$1 (and get away with it), I can wait a year and buy a candy bar with it. My \$1 has some inherent value.
In macroeconomics, \$USD are simply a means to inject liquidity into the market. If the world sets up a global savings fund, and puts \$1 into it, that money is moot. There won't be more candy bars next year than there are this year. The \$1 is just a means to make my exchange of candy bars convenient. It has no inherent value.
This is something of an over-simplification, and I'm no economist, so probably not entirely correct. However, I frequently encounter people who apply personal-finance microeconomics-style reasoning to discussions of goverment fiscal policy. I have found it to be incredibly difficult to introduce the above distinction, and I have no citations or sources. This is just how it makes sense to me, and my words are apparently insufficient.
So, does this distinction have a name? Is this distinction studied in any text and/or academic circles? What are some ways that the microeconomic dollar and the macroeconomic dollar are two different beasts? What are some simple ways to introduce this distinction to laypeople?
