Unit 1

Movements of ppg
Inside of curve: any point inside (unemployment, underemployment, famine, war, recession, depression)
Along the curve: on the curve
Shifts of the curve: can shift inside or outside the curve
Opportunity cost: next best alternative that you must give up in order to get something, form of trade-off
Law of increasing opportunity costs: as you produce more of one good (the far gone production of another good), will increase
Concave (bowed out) vs Constant (same, straight line) ppg
Productive efficiency: (Products are being produced in the least costly way, any point on the ppg) vs Allocative efficiency: (Products being produced are ones that are most desired by society)
Elasticity of Demand- Measure of how consumers react to a change in price
Inelastic Demand (demand for a good will not change, or will change very little regardless of price. Ex: soap, water, gas, insulin), Elastic Demand (demand will change greatly given a small change in price. Can have other substitutes. Ex: Coca-Cola, fur coat, steak), Unitary Elastic (no perfect society, equal to one)
Revenue (Price x Quantity) and Cost -
Fixed Cost: cost that does not change no matter how much of a good is produced (ex: mortgage, insurance, salary)
Variable Cost: cost that rises and falls depending upon how much is being produced (ex: utility, water or electricity, bills)
Marginal Cost: cost of producing one more unit of a good

Business Cycles: Fluctuations in economic activities that an economy experiences over a period of time
Expansion: Periods of economic upturn when output and employment are rising
Peak: Highest point, period in which business has reached a temporary maximum, at near or full employment
Contraction aka Recession: Period of decline in total output, income and employment

Trough: Lowest point, economy goes from recession to depression

Price Ceiling - legal maximum price meant to help BUYERS (excess demand) Lower prices for some consumers (ex: rent control) Shortages Long line for buyers Illegal sells above equilibrium price Price Floor - legal minimum price meant to help SELLERS (excess supply) Higher product prices Surplus Higher taxes Waste

Unit 1: Basic Economic Concept

Scarcity: fundamental economic problem of having seemingly unlimited human wants and needs in a world of limited resources Economics: science that deals with production, distribution, consumption of goods/services, or material welfare of humankind; financial considerations; economically significant aspects   1st Pillar of Wisdom: nothing in our material world can come from nowhere, nor be free; everything in our economic life has a source, destination, and cost that must be paid by someone 5 Key Economic Assumptions: 1) society’s wants are unlimited, but ALL resources are limited (Scarcity) 2) due to scarcity, choices are mandatory. Every choice has a cost. (Trade -Off) 3) everyone’s goal is to make choices that maximize satisfaction. Everyone acts in own “self-interest” 4) everyone makes decisions by comparing marginal costs and marginal benefits of every choice. 5) real-life situations can be explained and analyzed through simplified models and graphs C...

Unit 2

Real GDP: Price x Quantity ; value of output produced in constant based year prices that is adjusted for inflation. Can increase from year to year only if output increases. Nominal GDP: Price x Quantity ; value of output produced in current year prices. Can increase from year to year if either prices or output increases In the base year, current prices is equal to base year (constant) prices In years after the base year, nominal GDP exceeds real GDP In years before the base year, real GDP exceeds nominal GDP GDP Inflator: a price index used to adjust from nominal to real GDP In the base year, the GDP deflator = 100 For years after the base year, GDP Deflator > 100 For years before the base year, GDP Deflator < 100 Deflator Formula: new-old/old GDP Deflator = (nominal GDP/real GDP x 100) Inflation: a general rise in the price level (new[price index]-old[price index] /old x 100) will result in percentage Consumer Price Index: measures cost of ...
