What is economics?
– study of decision making in the presence of scarcity
-scarcity is unlimited wants with limited resources (everything is scarce)
-decisions made by rational people
-rational: the benefit of doing something is more than the cost, the person does it; if benefit is less than the cost, they won’t do it (based on own believe of benefit)
-even heroine addicts are rational (their benefit is more than cost)
-trailer park boys with iphones (replace computer and land line)
-wife coach purse while pregnant
*marginal benefit and marginal cost*
