An economy’s minimum wage equates a unit of the currency to an amount of labor time. For instance, in Marxist terms, a minimum wage of $15/hour sets a dollar equal to 4 minutes of simple labor power. At a macro level, this enables currency value to be defined in terms of simple labor. There are, however, at least two ways in which this connection between currency value and labor could be drawn. One way would be to adopt a labor command theory of currency value. In effect, Modern Monetary Theory (MMT) takes this approach. A second way would be to link the value of the currency to the commodity labor power. Adopting the second approach leads to a definition of currency value that is distinct from the MMT definition but closely (and simply) related to it. So far as policy implications go, especially in relation to MMT’s proposed job guarantee and prescriptions for price stability, there appear to be no important differences between the two approaches.
