Researchers found drinking enough water could be the chief factor in maintaining a healthy . Consumption function refers to the functional relationship between aggregate consumption and aggregate income C = f(y). One potential problem is that the consumption function cannot handle changes in the distribution of income and wealth. As noted above, the consumption function is an economic formula introduced by John Maynard Keynes, who tracked the connection between income and spending. Thankfully, the recession is very short and consumer spending on Kitty Chow increases to prerecession levels. If income changes by $1, then consumption changes by the value of the MPC.
