There is an engaging video about the noodle-shaving robots described in the Economics Out There on p. 66 of Economics for Life: Smart Choices for You? Besides being fun, it has some interviews in Chinese (with English subtitles) which have been popular with my Chinese-speaking students.

Play the video and use these or similar questions for discussion:

  • What created the incentive for the invention of the robots?
  • How do you represent the invention of the robots using a supply curve?
  • Explain two ways to read the supply curve for meals with noodles, comparing supply before and after the invention.
  • Will robots cause unemployment for workers?
