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 ...

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

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 p...

Positive : facts; claims that attempt to describe world as is; very descriptive. Ex: minimum wage laws cause unemployment Normative : opinions; claims that attempt to prescribe how world should be. Ex: government should raise minimum wage Wants : desires of the citizens Needs : basic requirements for survival Scarcity : problem unlimited wants and needs with limited resources; fundamental problem that all societies face Shortage : quantity demanded > quantity supplied Surplus : quantity supplied > quantity demanded Factors of Production : Capital - human: knowledge and skills workers gain through education and experiences // physical: human made objects used to create other goods and services Entrepreneurship - risk taker and innovative Land - natural resources Labor - work exhorted Production Possibilities Graphs (PPG, PPC, PPF): shows alternate ways to use resources, shows most that society can produce if it uses every available resource to bes...

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...
