10. What is GDP?

11. GDP GDP = Gross Domestic Product = Total Value of all Spending in an Economy = The Total Value of all final Goods and Services in an Economy regardless of who owns the productive assets. GDP = C + I + G + (X – M)

12. GNP GNP = Gross National Product = Total Income Earned by a nation’s factors of production regardless of where the assets are located

27. Macroeconomic Models

28. What is aggregate demand (AD)? Aggregate Demand is the aggregate (total) spending on goods and service in a period of time at a given price level.

30. What are the components of AD? C = all household consumption on durables, non-durables and services I = firm’s replacement investment(spending on capital to maintain productivity) or induced investment to increase production G = all government spending X-M = spending by foreigners on exports less domestic spending on imports

73. What is the neoclassical perspective?

74. The Neoclassical LRAS

75. Neoclassical (Free Market) LRAS LRAS perfectly inelastic at Full Employment Level of Output (Ymax) Potential Output = Quantity and Quality of FOPs not Price

76. Why is the LRAS vertical?

84. What is the Keynesian perspective?

85. The Keynesian SR/LRAS?

86. Keynesian SR/LRAS

87. Keynesian SR/LRAS Keynes argued that as there is nothing inherent in the economy to move the SR into the LR, then SRAS = LRAS NB In diagrams taking a Keynesian you may see the AS curve labeled Keynesian AS or simply LRAS as long as the diagram’s title makes clear which perspective is being adopted

88. Inflationary Gap in the Keynesian Perspective

98. Strengths of Monetary Policy

99. Weaknesses of Monetary Policy

100. The Neoclassical/Monetarist Challenge Argument that discretionary fiscal polices that try to stabilize the economy are so flawed that they actually cause instability Alternative policies Ensure steady supply of money Ensure price and wage flexibility Focus on supply-side policies to achieve economic growth

111. The Multiplier Effect

112. Marginal Propensity

113. Example of the Multiplier in Effect Assumption 60% of additional income spent on Consumption (MPC = 0.6) The Multiplier = 1/1-MPC

114. The Multiplier Effect

115. The Accelerator Theory & the Combined multiplier/accelerator effect Argues that small changes in GDP produces larger changes in investment spending. These fluctuations interact with the Multiplier effect to increase the momentum of business cycle.

137. Measuring Inflation The consumer price index (CPI) compares the value of a basket of goods and services in one year with a same basket in the base year.

138. Problems Measuring Inflation

139. The Phillips Curve

140. NRU = NAIRU If governments avoid demand-side expansionary policies Non-accelerating inflation rate of unemployment is achieved (NAIRU)

141. Long-run Phillips Curve

142. Phillips Curve

143. Phillips Curve

144. Neo-classical challenge to the Phillips Curve

145. LR Phillips Curve If expansionary policies adopted, inflation would increase to 4% or more. Real wages have fallen and firms hire additional labor.

146. LR Phillips Curve Unemployment is now below NRU at 4%. (b) Workers have fallen for the “money illusion” and slow to realize that real wages have fallen because inflation is actually over 4%.

147. LR Phillips Curve Unemployment is now below NRU at 4%. (b) Workers have fallen for the “money illusion” and slow to realize that real wages have fallen because inflation is actually over 4%.

148. LR Phillips Curve Once workers realize real wages have fallen they will demand at least a 4% pay rise. Real wages will return to previous levels and firm will fire workers. Unemployment has returned to (c)

149. LR Phillips Curve Any attempt to to increase AD will only result in temporary changes to unemployment but increasingly high rates of inflation

150. LR Phillips Curve Friedman argued that no trade off exists if governments do not use demand side policies.
