Claim:
A revenue causality analyzer, useful in association with price management systems, the revenue causality analyzer comprising: a time period selector configured to select a reference time period and a comparison time period; a data preparer configured to prepare transaction data including pricing data and volume data about products; a causality attributor configured to attribute at least one causality effect by analyzing the transaction data utilizing a causality equation; and wherein the causality equation is: ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ ( p i ⁢ ⁢ 2 ⁢ v i ⁢ ⁢ 2 e 2 ⁢ ⁢ k ) - ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ ( p i ⁢ ⁢ 1 ⁢ v i ⁢ ⁢ 1 e 1 ⁢ ⁢ k ) = ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ ( ( p i ⁢ ⁢ 2 ⁢ ⁢ k - p i ⁢ ⁢ 1 ⁢ ⁢ k e 1 ⁢ ⁢ k ) · v i ⁢ ⁢ 2 ⁢ ⁢ k ) + ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ ( ( p i ⁢ ⁢ 2 ⁢ ⁢ k e 2 ⁢ ⁢ k - p i ⁢ ⁢ 2 ⁢ ⁢ k e 1 ⁢ ⁢ k ) · v i ⁢ ⁢ 2 ⁢ ⁢ k ) ( ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ v i ⁢ ⁢ 2 ⁢ ⁢ k - ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ v i ⁢ ⁢ 1 ⁢ ⁢ k ) · ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ ( p i ⁢ ⁢ 1 ⁢ ⁢ k e 1 ⁢ ⁢ k ⁢ v i ⁢ ⁢ 1 ⁢ ⁢ k ) ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ v i ⁢ ⁢ 1 ⁢ ⁢ k ︸ + ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ v i ⁢ ⁢ 2 ⁢ ⁢ k · ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ ( p i ⁢ ⁢ 1 ⁢ ⁢ k e 1 ⁢ ⁢ k ⁢ ( v i ⁢ ⁢ 2 ⁢ ⁢ k ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ v i ⁢ ⁢ 2 ⁢ ⁢ k - v i ⁢ ⁢ 1 ⁢ ⁢ k ∑ k = 1 M ⁢ ∑ i = 1 N ⁢ v i ⁢ ⁢ 1 ⁢ ⁢ k ) ) ︸ .
