The least apparent illustration of how decisions are generally ‘at the margin’ would be: (i) Purchasing an additional novel after learning that all paper-backs at Borders are on sale for 25 percent off. (ii) Tossing a 6-year old cousin to the deep end of the pool as or else, ‘that child will never learn how to swim’. (iii) Constantly deciding to ‘play one final video game’ before going to the bed. (iv) Pouring more syrup on your pancakes before beginning a triathlon as you want additional fuel. (v) Sharing one more kiss previous to you and your important other start studying for the monthly economics quiz.
