Approx # of Year to Double = 70/ Annual Percentage Rate of Growth Sources of Economic Growth: 1. Increase resources 2. Increase productivity of existing resources Productivity = Real Output/ Unit of Input Increase productivity of resources by: 1. Improving health, education, training, motivation of workers 2. Improving capital quality and quantity 3. Improving organization and management 4. Reallocate labor from less efficient to more efficient industries -About 1/3 of U.S. growth comes from more resources; 2/3 comes from improved productivity. Business Cycle- alternating increases and decreases in the level of economic activity, extending over several years, varying in length and intensity. Business Cycle Phases: -Peak: temporary maximum of economic output. Economy is at full employment, nearing capacity; inflationary pressure exists -Recession: at least two consecutive quarters of negative Real GDP growth, income, unemployment. Economy may not experience price reductions because prices are “inflexible downward” unless recession is severe and prolonged. -Trough: bottom of reduction in output.
