Perfect example is the 50% Discount/Rebate policy at retail sale. Its the perfect integration of the opposite perspectives of micro and macro-eonomics and the Reason I titled my book Wisdomics-Gracenomics.
Macro-economics is about aggregates. Micro-economics is basically about individuals and individual factors and their effects.
Retail sale is the single universally participated in point in the entire economic process, hence a policy at that point is a SINGLE factor THAT ALSO EFFECTS THE AGGREGATE OF EVERYONE hence an integration of both micro and macro-economics.
