Consider a water supplier who determines sales rates with the goals of maximizing profits, protecting consumer welfare, and ensuring adequate future water supplies. Buyers are differentiated and can use the water for domestic, agricultural, and industrial purposes. We propose a leader-follower finite-horizon differential game. The leader (the water supplier) determines the selling price and the followers (consumers) react by requesting their optimal amount of water. We calculate a feedback Stackelberg equilibrium assuming that all user demand is satisfied (interior equilibrium). We compare two different tariff schemes: linear tariffs (the price paid is a multiple of the volume of water purchased), and increasing block tariffs (the unit price is lower for quantities of water that do not exceed a fixed threshold). We show that block pricing is never optimal and linear pricing is always preferred.

“…Moreover, the payoff of the social planner and that of companies are assumed to be linear quadratic. Over-exploitation of groundwater resources is also investigated in Esteban et al (2021). The possibility of regime shifts in freshwater ecosystems is included in the model when a critical water level is reached.…”

“…It is well‐established that modern human activities can lead to the deterioration of GDEs, thereby compromising the habitat of the diverse array of flora and fauna that reside within these ecosystems (Esteban et al, 2021). For instance, it has been reported that declining groundwater levels due to over‐pumping are linked to decreases in streamflow globally (de Graaf et al, 2019).…”

Current groundwater challenges have made evident that national and international groundwater law needs a thorough revision. In this article, we explore earth system law (ESL) and rights of nature (RoN) as possible approaches to rethink groundwater law. Taking inspiration from ESL scholarship, RoN literature, Indigenous worldviews, and socio‐ecological movements, we analyze law as a critical element of the human‐political‐social system, which creates regulatory institutions with the aim to provide a social order for humanity, an order that is being affected by deteriorating earth systems, including groundwater. Recognizing RoN and thinking law through the lenses of ESL involve a new understanding of what groundwater law could be and what the subject of the law could be. So far, little attention has been given to how these approaches can be used to redesign groundwater law, and what implications this could have on groundwater governance and sustainability. Therefore, this article explores the possibility of reforming groundwater law through the lenses of ESL and RoN. It investigates which legal mechanisms are being used to recognize RoN, and what their legal and practical implications have been so far. This article aims to contribute not only to advancing the academic debate on RoN and ESL but also to share light on different ways to reform groundwater law, which includes a new understanding of sustainability and socio‐nature relations.This article is categorized under: Human Water > Rights to Water Human Water > Water Governance Science of Water > Water and Environmental Change

“…Methodologically, the present paper relates to the literature exploring regime shifts in dynamic systems. Extant literature in this area has analysed regime shifts in groundwater resources (de Frutos Cachorro et al, 2019; Esteban et al, 2021), in fisheries (Costello et al, 2019) and mineral resources (Nkuiya, 2020). These follow the rich tradition of research on regime shifts in environmental and resource economics (Polasky et al, 2011).…”

Size matters: Optimal management of dynamic systems with varying size

Many natural and economic systems are managed to deliver the highest benefits to society but are subject to regime shifts. We specifically consider the variability of the size of the system itself as a key driver of a regime shift. We address the question of how the optimal management of these systems should vary with its size. Put simply, certain management options might work when the system is of a given size, while others might be preferred when the system has grown or shrunk. In this paper, we develop a model that allows us to analyse the effect of the size of the system on its optimal management. We apply this model to a case of water pollution in a reservoir/lake that varies in size over time: sometimes the lake is deep and sometimes it is shallow. Numerical simulations were conducted to compare optimal management of the reservoir with and without explicitly modelling its size variation. The findings show that the overall social costs of optimally managing pollution are significantly smaller when the variability in size is taken into account. This is due to differences in the timing and magnitude of the optimal control. The key implication is that the variability of the size of a system should be explicitly considered in this type of management problems.
