Unit 6 - Economic Growth & Productivity (From Ms. McCartney's Powerpoint)

Economic Growth

• Sustained increase in Real GDP over time.
• Sustained increase in Real GDP per Capita over time. 

Grow - leads to greater prosperity for society. It lessens the burden of scarcity and increases the level of well-being.

• Conditions
• Rule of law.
• Sound Legal & Economic Institutions.
• Economic freedom.
• Respect for private property.
• Political & Economic stability -Low inflation expectancy.
• Willingness to sacrifice current consumption.
• Saving.
• Trade.

Physical Capital - product of investment (sensitive to interest rates and expected rates of return).

• Tools, machinery, and factories.
• Takes capital to make capital.
• Capital must be maintained.

Technology & Productivity

• More technology = Increases productivity.
• Productivity - output per unit of input.
• Labor productivity - output per worker.
• More Productivity = Economic Growth.
• Research + development and innovation + invention = Increases in technology.

Human Capital - people are the most important resources, so they must be developed.

• Education.
• Economic Freedom.
• The right to acquire private property.
• Incentives.
• Clean water and stable food supply.
• Access to technology.

How to show Economic Growth Graphically

1. LRAS shifts to the right.
2. PPC shifts outward. 

Obstacles to Growth

• Economic and Political Instability – such as high inflation expectancy.
• No of the rule of law.
• Diminished private property rights.
• Negative incentives.
• Lack of savings.
• Excess current consumption.
• Failure to maintain existing capital.
• Crowding out of investment – government deficits & debts increasing long term interest rates.
• Restrictions on free international trade.

Unit 5 - April 3

Supply Side Economics / Reaganomics - tends to believe that the AS curve will determine level of inflation, unemployment, and economic growth.

• To increase economy - AS shifts right.
• Companies benefit - AS.
• Consumers benefit - AD.
• Focus on the marginal tax rate - amount of tax paid on additional dollar of income.
• By reducing the marginal tax rate, it will encourage more people to work longer.
• High marginal tax rate reduces saving because saving money taxed at a higher rate on profit/interest.

Laffer Curve 

• Tax Rates and Government Revenue have an inverse or a trade off relationship.
• High tax rate = Low government revenue.
• There is a U-shaped, because it always tries to maximizes government revenue.
• As tax rate increase from 0, tax revenue increases from 0 to some maximum number then they decline.

3 Criticisms of the Laffer Curve

1. Where the economy is located on the curve is difficult to determine.
2. Tax cuts also increase demand, which can fuel inflation and demand may exceed supply.
3. Research state that tax rate impact people's incentive to work, invest, and save.

Unit 5 - April 2

Supply Shock - rapid and significant increase in resource prices, which cause the SRAS to shift which results in producing a shift in the SRPC curve.

• Examples
• Oil embargo.
• Increase in input prices.
• Wages heights
• Could be positive or negative, depending on what it is.
• Could lead to stagflation - simultaneous increase in inflation and unemployment.

Disinflation - reduction in inflation rate from year to year, which can be seen in the LRPC.
