The permanent income hypothesis is a theory of consumer spending stating that people will spend money at a level consistent with their expected long-term average income. The level of expected long-term income then becomes thought of as the level of “permanent” income that can be safely spent.

Friedman divides the current measured income (i.e., income actually received) into two: permanent income (Yp) and transitory income (Yt). Thus, Y = Yp + Yt. Permanent income may be regarded as ‘the mean income’, determined by the expected or anticipated income to be received over a long period of time.

What is the difference between permanent income hypothesis and life cycle hypothesis?
The LCH pays more attention to the motives for saving than the PIH does and argues strongly in favour of including wealth as well as income in the consumption function. The PIH, on the other hand, pays more attention to the way in which individuals form expectations about their future incomes than the LCH does.
What is MPC and APC?

What is Keynesian consumption function?
The consumption function, or Keynesian consumption function, is an economic formula that represents the functional relationship between total consumption and gross national income.
Why is consumption smooth?

The permanent income hypothesis predicts that a temporary change in income will have a smaller effect on consumption than is predicted by the current income hypothesis. Other factors that affect consumption include real wealth and expectations.
Why does the APC differ from MPC?
MPC and APC are different because MPC measures the effect of change of income on change of consumption, whereas APC measures the effect of the total level of income on the total level of consumption.
