Paasche price index.

The Paasche price index is calculated as $$ \frac{\sum_i p^t_i q^t_t}{\sum_i p^b_i q^t_i}.$$ Arguments can either be vectors or matrices.

Usage

p_paasche(pt, pb, qt)

Arguments

pt

A n-vector (or m x n matrix) of prices in current period.

pb

A n-vector (or m x n matrix) of prices in the baseline period.

qt

A n-vector (or n x n matrix) of quantities in the current period.

Value

Price index between current an baseline period (number or vector).

Examples

Pt <- matrix(1:6, ncol = 2)
Pb <- Pt*0.7
Qt <- matrix(2:7, ncol = 2)
p_paasche(Pt, Pb, Qt)
#> [1] 1.428571 1.428571 1.428571
p_paasche(Pt[1,], Pb[1,], Qt[1,])
#> [1] 1.428571
