In ErikOSorensen/pppindexr: Price and Quantity Indices for International Comparisons

Laspeyre price index.

Description

The Laspeyre price index calculated as

\frac{∑_i p^t_i q^b_t}{∑_i p^b_i q^b_i}.

Arguments can either be vectors or matrices.

Usage

p_laspeyre(pt, pb, qb)

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

Value

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

Examples

Pt <- matrix(1:6, ncol = 2)
Pb <- Pt*0.7
Qb <- matrix(2:7, ncol = 2)
p_laspeyre(Pt, Pb, Qb)
p_laspeyre(Pt[1,], Pb[1,], Qb[1,])
