WITH LIMITED RESOURCES 22 | CHAPTER 1 SCARCITY UNLIMITED WANTS CLASH WITH LIMITED RESOURCES. EVERYONE FACES SCARCITY. ECONOMICS FOCUSES ON THE ALLOCATION OF SCARCE RESOURCES. 2 WHEN MAKING DECISIONS, ONE MUST TAKE INTO ACCOUNT TRADEOFFS AND OPPORTUNITY COSTS. 24 | CHAPTER 1 OPPORTUNITY COST THE NEXT BEST ALTERNATIVE; WHAT YOU GIVE UP TO DO SOMETHING OR PURCHASE SOMETHING ELSE 3 SPECIALIZATION LEADS TO GAINS FOR ALL INVOLVED. 26 | CHAPTER 1 THE GAINS FROM SPECIALIZATION INDIVIDUALS TEND TO WORK IN CAREERS MOST SUITED TO THEM 4 PEOPLE RESPOND TO INCENTIVES, BOTH GOOD AND BAD. 28 | CHAPTER 1 EXECUTIVE BONUSES Good Incentive – Wall Street traders and bankers were paid bonuses based on their productivity.
