With modern money theory (MMT) receiving impressive attention, the implications this theory has for developing countries have also been discussed more intensely. Emphasizing both its strengths and gaps provides a great chance to further develop macroeconomic strategies for poverty reduction and environmental sustainability.

In brief, the theory starts from the statement that money is issued by the government and brought into circulation via its expenditures. The government does not rely on taxes to fund expenditures when it is itself the source of money. Therefore, money can be created upon demand, is not limited, and can be used by the government to finance all expenditures it considers necessary to achieve policy goals such as full employment or a Green New Deal. The reason why agents in the economy accepts this money only consisting of numbers without any intrinsic value is the obligation to pay taxes. Since the state has the power to impose taxes, individuals need to get hold of money as this is the only way to meet their obligations; this is how the currency is accepted as a means of payments. The government thus has the power to run unlimited deficits because the fact that money is needed to pay taxes guarantees its acceptance even if those taxes do not cover expenditures. In fact, the government should run deficits because it creates the demand required for full employment while a balanced budget constrains it. The government cannot go bankrupt because there is no lack of currency it issues itself. The conditions identified by MMT for the system to work are the following: 1) the country must be sovereign of its own currency and 2) inflation needs to be kept under control. Once the latter starts accelerating due to increased nominal demand stemming from government expenditures, taxes can be increased in order to withdraw money from circulation. However, as long as full employment is not achieved, prices are argued to remain stable.
