Using the data from the National Bureau of Economic Research (NBER) report, http://www.nber.org/cycles.html, and what you learned in lecture and the textbook, answer the following questions.

During the last cycle, the U.S. economy set a record for expansion (120 months) after a brief contraction (8 months). During July 1981, the economy hit a turning point.
