4. 17 - 3

5. 17 - 4 Key Growth Factors 1.Increases in the Quantity & Quality of Natural Resources 2.Increases in the Quantity & Quality of Human Resources 3.Increases in the Supply (or Stock) of Capital Goods 4.Improvements in Technology 5.Households, Businesses, and Government Must Purchase the Economy’s Expanded Output 6.The Economy Must Achieve Economic Efficiency (productive and allocative) as well as Full employment

6. 17 - 5 Increases in the Quantity & Quality of Natural Resources Examples of natural resources? Questions: Where will we get the resources? How will we get the resources? Who will we compete with to get the resources? Solve this problem using the tools of monetary and fiscal policy available Key growth factors 4 Supply Factors that make growth possible

7. 17 - 6 A Problem solving strategy 1.Create a solution that will deliver the desired result. 2.Find a way to make the solution work. 3.Select the best tool from monetary and fiscal policy that will bring your solution to life.

8. 17 - 7 Problem You are in charge of economic policy Your mission is to increase the rate of growth of U.S. GDP from 0% to 4% per year in 3 years. You can use the tools of monetary policy and fiscal policy You are to focus on increasing the quantity and quality of natural resources to achieve your goal. Please try to avoid adding to the global warming problem. How would you solve this problem?

9. 17 - 8 Increases in the Quantity & Quality of Human Resources Questions: Where will we get the resources? How will we get the resources? Who do we compete with to get the resources? What will we do with the resources that are of lower “quality”? Key growth factors Supply Factors that make growth possible

10. 17 - 9 Increases in the Supply (or Stock) of Capital Goods Example of capital goods? What capital goods will we increase the supply of? Who will pay for those capital goods? What is the rationing mechanism for determining what goods will be produced and which ones will not? Key growth factors Supply Factors that make growth possible

11. 17 - 10 Improvements in Technology Examples of technological improvements? Questions: Which technologies should we improve or grow? Who should pay for that? Who should get them? Key growth factors Supply Factors that make growth possible

12. 17 - 11 Households, Businesses, and Government Must Purchase the Economy’s Expanded Output No unplanned inventories Resources fully employed Remember the circular flow model? Questions: How should we increase demand? How should we manage the increase in demand? How long will we be able to increase demand? Key growth factors for growth to be realized Demand Factor

13. 17 - 12 Key growth factors for growth to be realized Efficiency Factor The Economy Must Achieve Economic Efficiency (productive and allocative) as well as Full employment Questions: How can we achieve / approach productive efficiency? How can we achieve /approach allocative efficiency? How can we achieve full employment?

14. 17 - 13 PRODUCTION POSSIBILITIES ANALYSIS Supply factors make the shift possible, the Demand and efficiency factors make it real Economic Growth A B C D a b Capital Goods Consumer Goods 0

15. 17 - 14 PRODUCTION POSSIBILITIES ANALYSIS Increase inputs and increase productivity of those inputs to raise real output and income. Labor and Productivity Labor productivity – real output per hour of work. Total output = worker hours x labor productivity Labor Productivity – measured by real output per worker hour. Real GDP = Hours of Work X Labor Productivity

16. 17 - 15 Labor and Productivity Size of employed labor force Average hours of work Labor Inputs (hours of work) Technological advance Quantity of capital Education and training Allocative efficiency Other Labor Productivity (average output per hour) Real GDP Real GDP = hours of work x labor productivity x =

18. 17 - 17 ACCOUNTING FOR GROWTH Sources of productivity growth Technological Advance - largest contributor to increases in the productivity of American labor – 40% Quantity of Capital – 30% Education and Training - Human Capital – 15% Nation's infrastructure - public capital goods such as highways and sanitation systems, levee systems, bridges, water systems

25. 17 - 24 Sources of Increasing Returns More Specialized Inputs Spreading of Development Costs Simultaneous Consumption Network Effects - Increases in the value of a product to each user, including existing users, as the total number of users rises Learning by Doing Global Competition PRODUCTIVITY ACCELERATION: A NEW ECONOMY?

26. 17 - 25 Macroeconomic Implications of stronger productivity growth and greater global competition. More Rapid Economic Growth Low Natural Rate of Unemployment Growing Tax Revenues Skepticism About the New Economy - too soon to judge whether the high productivity advances between 1995 and 2002 are permanent or transitory. PRODUCTIVITY ACCELERATION: A NEW ECONOMY?

27. 17 - 26 Proponents of the New Economy – Innovations in computers and communications, together with global capitalism, are greatly boosting U.S. productivity and the economy's potential economic growth rate. PRODUCTIVITY ACCELERATION: A NEW ECONOMY?

28. 17 - 27 IS GROWTH DESIRABLE AND SUSTAINABLE? The Antigrowth View – economic growth does not resolve socioeconomic problems such as income inequality.
