An alternate, and more conventional, approach to the measurement of permanent income is in terms of a weighted average of past incomes, that is, Yp =XWtYt, t =-x. where Wt are the weights and Yt the measured income in time period t.
What is the consumption function formula?

How the consumption puzzle is solved by Permanent Income Hypothesis?
On the basis of this hypothesis Modigliani solved the puzzle by putting forward the argument that; because wealth doesn’t vary proportionally with income from person to person or from year to year we should find that high income corresponds to a low average propensity to consume, when looking at data across individual …
How is the consumption function based on permanent income?
Friedman explain in A Theory of the Consumption Function how consumers interact with money based off of not just windfall gains, but through their permanent income because consumers will save when they expect their long term income to rise.

What is the definition of the consumption function?
Yd = disposable income (income after government intervention – e.g. benefits, and taxes) a = autonomous consumption (consumption when income is zero. e.g. even with no income, you may borrow to be able to buy food) b = marginal propensity to consume (the % of extra income that is spent). Also known as induced consumption.
