The U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost.
Like gold, U.S. dollars have value only to the extent that they are strictly limited in supply. But the U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost. By increasing the number of U.S. dollars in circulation, or even by credibly threatening to do so, the U.S. government can also reduce the value of a dollar in terms of goods and services, which is equivalent to raising the prices in dollars of those goods and services.
Inflation is certainly low and stable and, measured in unemployment and labour-market slack, the economy has made a lot of progress. The pace of growth is disappointingly slow, mostly because productivity growth has been very slow, which is not really something amenable to monetary policy. It comes from changes in technology, changes in worker skills and a variety of other things, but not monetary policy, in particular.
The American people are among the most productive in the world. We have the best technologies. We have - great universities. We have entrepreneurs.
Over the years, the U.S. economy has shown a remarkable ability to absorb shocks of all kinds, to recover, and to continue to grow. Flexible and efficient markets for labor and capital, an entrepreneurial tradition, and a general willingness to tolerate and even embrace technological and economic change all contribute to this resiliency.
