Abstract

This paper presents a methodology for market definition based on supply and demand estimations. This methodology is applied to the dishwashing detergent industry in Argentina, using data from the period 2022-2023. The results are compared with those derived from demand-only estimations, concluding that two distinct relevant markets can be identified in Argentina: one comprising the two leading detergent brands and another encompassing all remaining brands.
