"A country's rate of economic growth is determined solely by the amount of resources available to the country." Comment on this statement.

Increases in the availability of resources, that is, labor and capital used in the production of goods and services account for only part of a nation's economic growth. The efficiency with which these factors of production are used also affects economic growth. Increases in the efficiency of production result from increases in the education and skill levels of the labor force and from newer and more efficient technology. In addition, the factors of production are not fully employed all the time. During an expansion or recovery, the use of the factors of production increases, which leads to an increase in production and output.
