1. What backs the U.S. dollar? Include the disticntion between commodity money and flat money in your answer.

The U.S. dollar is backed by the full faith and credit of the U.S. government, rather than by a physical commodity like gold or silver. This makes it a form of flat money.

To understand the distinction between commodity money and flat money, we need to delve into their definitions:

1. Commodity Money: Commodity money refers to a type of currency that has value in itself based on its inherent qualities. Historically, gold and silver have been used as commodity money because they possess intrinsic value and are universally accepted as valuable. Back when the gold standard was in effect, the U.S. dollar could be exchanged for a fixed amount of gold, making it a form of commodity money.

2. Flat Money (or Fiat Money): Flat money, on the other hand, is a form of currency that derives its value from government decree or legal tender laws. It is not backed by a physical commodity, but instead, its value is based on the confidence and trust people have in the government issuing the currency. The U.S. dollar is considered flat money, as its value is determined by the economic stability and strength of the U.S. government, as well as the level of confidence people have in it.

Now, to determine what backs the U.S. dollar specifically, we need to understand that it is no longer directly backed by a specific physical commodity like gold. In 1971, the U.S. officially ended the convertibility of the dollar to gold, effectively severing the gold standard. Since then, the U.S. dollar operates on a system of fiat money, where its value is determined by the trust and confidence placed in the U.S. government and the stability of the U.S. economy.

It's important to note that while the U.S. dollar is not directly backed by a physical commodity, the U.S. government still maintains the responsibility of managing its value, controlling inflation, and ensuring the currency's stability through monetary policies implemented by the Federal Reserve. The U.S. dollar's status as the world's primary reserve currency and its widespread use in international transactions also contribute to its value.
