摘要

本研究的目的是估计饮用水供应的边际成本，并分析对突尼斯更有效、公平和收入充足的自来水收费的影响。此外，本文旨在建立一种新的饮用水定价模型。突尼斯水务公司的定价侧重于设定水价以覆盖平均成本，通常采用增加堵塞率的设计。这导致大量的饮用水被浪费。为了促进定价模型的有效估计，我们尝试为包括Box-Cox变换在内的多种产品引入广义超对数(GT)成本规范。事实证明，提供一立方米水的边际社会成本必须由两部分组成:体积费，每立方米0.048欧元，连接水费，每公里0.055欧元。

The generalised translog cost function to estimate tariffs for potable water: The case of Tunisia

The present study aims to estimate the marginal cost of potable water supply and analyse the implications for more efficient, equitable and income-adequate tap water tariffs in Tunisia. Furthermore, this article aims to develop a new pricing model for potable water. Pricing by the Tunisian water utility focuses on setting water prices to cover average costs, often using designs that increase clogging rates. This results in a large volume of potable water being wasted. To facilitate the efficient estimation of pricing models, we attempt to introduce generalised translog (GT) cost specifications for multiple products including Box-Cox transformations. It turns out that the marginal social cost of providing a cubic meter of water must consist of two components: volumetric charges, at €0.048/m3 , and connection water charges, of €0.055/km.

期刊介绍： The African Journal of Agricultural and Resource Economics (AfJARE)/Journal Africain d’Economie Agricole et des Ressources (JAEAR) is a publication of the African Association of Agricultural Economists (AAAE). The journal publishes original research about how African agriculture interacts with local and global economic systems and policy regimes in its impacts upon people. The scope of the journal covers the roles of markets, technology, policy, institutions and the natural environment in shaping the lives of well being of Africans engaged in agricultural activities. The journal strives to nurture and enhance the capacity of African professionals to conduct and publish scientific research and provides a venue for communicating and disseminating their findings. Multi-disciplinary, problem-oriented articles are encouraged. Submissions may deal with teaching, research extension, consulting, advising, entrepreneurship and administration. The Chief Editors and Editorial Board, under the general direction of the AAAE President, Executive Committee and Council are charged with implementing Journal policy to serve members of AAAE. The main section of the journal publishes technical research articles while a small section is devoted to publishing brief notes with important policy content and book reviews. The journal is a quarterly publication.
