MACROECONOMIC APPROACHES AND PATHWAYS n The Two Main Schools of Thought The two main approaches to macroeconomics are based on two schools of thought: n Classical macroeconomics n Keynesian macroeconomics (Bade slide 4)
MACROECONOMIC APPROACHES AND PATHWAYS Classical macroeconomics is a body of theory about how a market economy works and why it experiences economic growth and fluctuations. n The economy will fluctuate, and growth will slow down from time to time. n But no government remedy can improve the performance of the market. n The classical view = markets work well and deliver the best available macroeconomic performance. n (Bade slide 5)
MACROECONOMIC APPROACHES AND PATHWAYS Classical macroeconomic fell into disrepute during the 1930 s, which was a decade of high unemployment and stagnant production throughout the world. (i. e. , Great Depression) n Classical macroeconomics predicted that the Great Depression would end, but gave no method for ending it more quickly. n (Bade slide 6)
MACROECONOMIC APPROACHES AND PATHWAYS Keynesian macroeconomics is a body of theory about how a market economy works that stresses it inherent instability and the need for active government intervention to achieve full employment and sustained economic growth. n John Maynard Keynes, in his book “The General Theory of Employment, Interest, and Money, ” began this school of thought. n Keynes’ theory was that too little consumer spending and investment lead to the Great Depression. n (Bade slide 7)
MACROECONOMIC APPROACHES AND PATHWAYS Keynes’ solution to depression and high unemployment was increased government spending. n But Keynes predicted that his policy aimed at curing unemployment in the short term might increase it in the long term. n This prediction became reality during the 1960 s and 1970 s, when inflation exploded, growth slowed, and unemployment increased. n It was time for another challenge to the mainstream: new macroeconomics n (Bade slide 8)
MACROECONOMIC APPROACHES AND PATHWAYS n. The New Macroeconomics New macroeconomics is a body of theory about how a market economy works based on the view that macro outcomes depend on micro choices—the choices of rational individuals and firms interacting in markets. n New classical macroeconomics incorporates the ideas of classical economists that markets work and new Keynesian macroeconomics that markets adjust slowly. n (Bade slide 9)
MACROECONOMIC APPROACHES AND PATHWAYS The key difference between the two new schools is in their view of how quickly price and wages adjust in the face of excess demand or excess supply. n But this difference is tiny, and a consensus is emerging. n n. The n Road Ahead We follow the new consensus and begin with an explanation of what determines real GDP and employment and the pace of economic growth. (Bade slide 10)
Gross Domestic Product “One person’s spending is another person’s income. ”
Gross Domestic Product n n n The gross domestic product, or GDP, is commonly used to measure economic growth. The GDP in the dollar value at market prices of all final goods and services produced in the economy during a stated period. Final goods are goods intended for the final user. n For example, gasoline is a final good; but crude oil, from which gasoline and other products are derived, is not. (NCEE slide 26)
Gross Domestic Product n n GDP also “aims to be a full count of the value of everything that is produced. ” Includes only those items that are traded in U. S. markets. n GDP does not include: sale of used goods (used cars) n sale of intermediate goods n illegal transactions n purely financial transactions (A financial transaction does not n involve production of a good or service. It is a transfer of assets. ) do-it-yourself activities n imports (goods made outside of U. S. ) n
How GDP is Measured Business Investment: a. Gross private domestic investment (GPDI), or business investment - sum of all business spending on capital investment and unplanned inventories. Government Spending (Carper, 170 -171) - Federal, state and local governments purchase approx. $1 of every $5 worth of products and services
How GDP is Measured Net Exports a. Exports (products sold to other countries) b. Imports products purchased from other countries includes net income from assets abroad (Carper, 172)
C=Consumption Spending I=Investment Spending G=Government Spending NX=Net exports (Exports minus Imports) I The Financial Market $ Households Expansionary policy reduces government revenues Incomes M X The Output Market Government borrows crowding out both consumption and Investment. T Rest of World G C Government T T=Taxes TR=Government Transfer Payments S=Savings G NX I Expansionary policy adds extra flows of government spending Firms TR Expenditures The Input Market

Part C: Measuring Short-Run Economic Growth n Before using GDP to measure output growth, we must first adjust GDP for price changes. n Let’s say GDP in Year 1 is $1, 000 and in Year 2 it is $1, 100. Does this mean the economy has grown 10 percent between Year 1 and Year 2? n n n Not necessarily. If prices have risen, part of the increase in GDP in Year 2 will merely represent the increase in prices. We call GDP that has been adjusted for price changes real GDP. If it isn’t adjusted for price changes, we call it nominal GDP. To compute real GDP in a given year, use the following formula: Real GDP in Year 1 = (nominal GDP x 100) / price index
n To computer real output growth in GDP from one year to another; n Subtract real GDP from one year to another; n n n Divide the answer (the change in real GDP from the previous year) by real GDP in Year 1. The result, multiplied by 100, is the percentage growth in real GDP from year 1 to Year 2. n n Subtract real GDP for Year 2 from real GDP in Year 1. (If real GDP declines from Year 1 to Year 2, the answer will be a negative percentage. ) Here’s the formula: Output growth = (real GDP in Year 2 – real GDP in Year 1) real GDP in Year 1 x 100 Example: If real GDP in Year 1 = $1, 000 and in Year 2 = $1, 028, then the output growth rate from Year 1 to Year 2 is 2. 8%: (1, 028 – 1, 000)/1, 000 =. 028, which we multiply by 100 in order to express the result as a percentage (2. 8%).
n To understand the impact of output changes, we usually look at real GDP per capita. To do so, we divide the real GDP of any period by a country’s average population during the same period. n This procedure enables us to determine how much of the output growth of a country simply went to supply the increase in population and how much of the growth represented improvements in the stand of living of the entire population. n
Example, let’s say the population in Year 1 was 100 and in Year 2 it was 110. What was the real GDP per capita in Years 1 and 2? Year 1 Real GDP per capita = Year 1 real GDP Population in Year 1 = $1, 000 100 = $10 Year 2 Real GDP per capita = $1, 028 110 n = $9. 30 In this example, the average standard of living fell even though output growth was positive. Developing countries with positive output growth but high rates of population growth often experience this condition.
