As physical capital per worker decreases, what happens to real GDP per worker? 2. “The GDP deflator takes into account price changes of both domestic and foreign goods consumed by a typical consumer.” True or false? Explain. 3. The text distinguishes between an economic expansion as part of the business cycle and long-run economic growth. Concisely explain the difference between these two terms. 4.
