Scarcity – the goods available are too few to satisfy individuals’ desires. Scarcity is constantly changing We focuses on coordination rather than on scarcity because the quantity of goods, services, and usable resources depends on technology and human action. Micro is the study of individual choice, and how that choice influenced by economic forces. Ex: pricing policies of firms, households’ decisions, how markets allocate resources Macro is the study of economy as a whole Ex: inflation, unemployment, business cycle, growth Use “model” to study human (is a framework that places the generalized insights of the theory in a more specific contextual setting) Traditional model = looking at self-interest Behavioral model = enlightened self-interest Policymakers need to understand the empirical evidence supporting the theory as well as real-world economic institutions to make policy recommendations Self-interest selfish Try to play the game respectfully use other people for their own good, don’t care about the consequences, play rudely Need to be rational when making decision.
