What is a chain-type index?

Use real (chain-type indexes or chain-dollar) estimates when you want to show how output or spending has changed over time. The percent changes in quantity indexes exactly match the percent changes in chained dollars, so they can be used interchangeably for making comparisons.

Which consumption is used in the calculation of Laspeyre’s index number?

That estimate is based in part on the observed past differences between the chained CPI-U and the traditional CPI-U and CPI-W.

What are the advantages of chain weighted CPI?

Chain-weighted CPI can capture both general changes in spending, as consumer preferences change, and substitution effects, when relative prices change. The adjustments in chain-weighted CPI make it a better measure of the cost of living, but a less accurate measure of inflation.
