i majored in econ. its super easy.
Supply and Demand, just remember, Equilibrium occurs where S=D, if there is too much of one or the other, a surplus or deficit forms

Elasticity %change P/% change in Q. land is perfectly inelastic. E=100000000000000000000, because no matter what the price change, there will be no change in quantity consumed.
Stuff like wheat is very elastic, if someone sells wheat for a lot more than the other farmer, no one will buy it from him. E is near zero

Aggregate Demand Curces, just add all the demand curves horizonally

Social Surplus=Net benefit to society, this stuff is created when benefits of something outweight its costs, like giving money to people who live near airports to make them happy about their [censored] conditions

Intermodal Consumption Models- Pretty sure this just means how consumption changes over time

Remember, if you are ever confused, just remember when Marginal Cost=Marginal Benefit, we have achieved the efficient solution. Micro is so easy if you dont do well you are a moron.
