The Importance of Saving and Investment The catch-up effect refers to the condition that, other things being equal, it is easier for a country to grow fast if it starts out relatively poor. Once the country becomes richer, diminishing returns sets in. 5

Control of Population Growth  Population is a key determinant of a country’s labor force.  Large populations tend to produce greater total GDP.  However, GDP per person is a better measure of economic well-being, and high population growth reduces GDP per person.  Thomas Malthus theory of population growth and economic well-being. Research and Development, Epilogue  The advance of technological knowledge has led to higher standards of living.  Most technological advance comes from private research by firms and individual inventors.  Government can encourage the development of new technologies through research grants, tax breaks, and the patent system.  There are pros and cons to productivity gains though, show Solman DVD video on productivity. 7
