Why, if people want to work, do they sometimes find themselves unemployed? Why do economies experience inflation, and doest it mater if they do? Why do exchange rates change and what will be the impact of such changes on imports and exports? Why do economies grow over the longer term and why do they fluctuate in the short term and what governments can do to prevent these fluctuations. How economies can sustain faster economics growth? Studying ways to answer these and other related questions is at the heart of this course. This macroeconomics course sheds also the light on what is happening around the world, from the Great Depression in the 1930s, to the Japanese economic slump that started in the early 1990s, to the large U.S. current account deficit and to the financial crises of 2008.
