Abstract

International audience; Based on the idea that in real markets firms have some freedom to set their output prices and negotiate input unit costs, this paper introduces a new approach for value-based performance decomposition as the product of direct price and quantity effects. Our framework relies on the axiomatization of a value transformation set on which quantity, price and value distance functions can be defined. The methodology developed allows for various degrees of dependency between quantity and price as well as for different degrees of freedom in price setting. The value-based performance decomposition can encompass all traditional measures such as cost, revenue, profit and profitability efficiencies. An application on French cattle farms illustrates the appeal of our approach for practitioners.

Abstract

International audience; We propose in this article a value indicator to assess decision-maker units (DMUs) overall performance change. We provide a decomposition of this value indicator to focus on the quantity change effect (productivity change) and the price change effect (price performance change), which is determined indirectly. The latter further decomposes into a firm-specific price advantage change and a price environment change. These global decompositions can further be applied to each input and output.

Abstract

In this paper, we develop a price advantage measure obtained as the difference between efficiency scores computed with quantity-based and value-based data. This measure is interpreted as an increase in the firm's profit rate due to a favourable input and output price environment. Compared to traditional allocative efficiency measure, which uses only the evaluated firm's prices, price advantage measure considers prices of peers in the market. Our main contribution is to show that total-price advantage decomposes into the sum of output- and input-specific price advantages. The application of the measure to a French farm's dataset in the context of the successive common agricultural policy reforms – aiming at the liberalization of agricultural prices (1992–2013) – illustrates our theoretical model.
