Economics is the study of mankind in the ordinary business of life ( Alfred Marshall-1791)

Allocation of parking spaces, deciding how many credit hours to take, deciding what to major (business vs LA, Sciences) considering career opportunities, working or going to school, etc. are all economic decisions

2. The economic problem arises from the unlimited human wants relative to limited resources.

3. The scarcity - choice - opportunity cost framework. Because of scarcity, we must make choices and the choices we make entail costs (OC)

4. Opportunity cost - the value of the best foregone alternative.

Examples – OC of going to school =>income you would earned working

OC of big building stadium => other services given up (library, computing, housing services)

OC of using land for wild life => other things land can be used for

4. An Example of Constant Opportunity Cost

Budget =$5.00; PHD= $0.50; PHAM=$1.00

Note: 1) the opportunity cost of each

additional hamburger is the 2 hotdogs which must be given up. This is a case of constant OC.
