• A model of macroeconomics learned at the Intro to Economics level, everything is linear.
  • Since assumptions about human behavior and consumption are linear, the resulting macro model is also linear.
  • Some may doubt this reasoning (blu3mo)(nishio).
    • As the level advances, more complex models may emerge.
    • It seems likely that although micro-level models are complex, when averaged or summed at the macro level, they become linear (blu3mo).
  • I think assuming y=f(x) depends on a single value is fundamentally flawed; it should be a probability variable P(y; x) (nishio).
