This is an advanced undergraduate course in macroeconomic theory with the focus on economic growth. The standard of living in a country is determined by its capacity to produce goods and services. Why are some nations richer than others? Why is there economic growth? Will it continue forever? What factors play a role in shaping the economic success of a nation? We will study the key ideas and insights of modern growth theory and apply them to explain the facts from the history of technology, economic performance of the world and growth experience of different nations.
