  29. 29. Scarcity is the fundamentaleconomic problem that human wantsexceed the availability to time,goods, and resources. Individuals andsociety therefore can never haveeverything they desire. 29

  38. 38. Collect data and test the model Develop a model based on assumptionsIdentify theproblem 38
  39. 39. Ceteris paribus holds “all otherfactors unchanged” that might affect aparticular relationship. If thisassumption is violated, a modelcannot be tested. Another reasoningpitfall is to think association meanscausation. 39
