Ch. 7: The fact that in Canada, real GDP per year was $2,633 in 1870 and $46,705 in 2017 implies every year, the growth rate was 1.98% per year.
False; If real GDP per person, beginning at $2,633, were to increase by 1.98% every year. Some years it rose by more, other years it rose by less, and in other years it fell. The growth rate of 1.98% per year ignores short-run fluctuations around the long-run trend and represents an average of growth for real GDP per person over many years.
From 1890 to 2017, countries with lower levels of real GDP per person than the United States all had growth rates that are lower than that of the United States.

Ch. 7: The traditional view of the production process is that capital is subject to constant returns
False; The traditional view of the production process is that capital is subject to diminishing returns: As the stock of capital rises, the extra output produced from an additional unit of capital falls.

As a result, although higher saving leads to higher growth for a period of time, growth eventually slows down as capital, productivity, and income rise.

When they are sold to the grocery store chain in the second quarter they will count as investment, but this increase will be offset by the decrease in the change in inventories.
