Marshall-Edgeworth Method
Marshall-Edgeworth method uses both the current year as well as the base year prices and quantities. Marshall-Edgeworth Index can be computed using the following formula,
where Q0, Q_{1}, P_{0} and P_{1} follow the usual notations.
Marshall-Edgeworth Index
Marshall-Edgeworth Index is simple to construct but suffers from the problems in data collection. However, the Marshall-Edgeworth index closely approximates the results obtained by the Fisher's Ideal index.
