This paper focuses on the disparity between willingness-to-pay and willingness-to-accept indices in nonmarket valuation. The substitution effect makes agents value net losses higher than opportunity losses. In regard to net losses, we show that imperfect substitutability respectively induces...

This paper compares guilt alleviation and competition for social status in the private provision of a public good. When agents are intrinsically impulsed, that is, they mostly provide the public good in order to alleviate their guilt, they tend to free-ride. In contrast, when agents are...

We evaluate the impact of three auction mechanisms the BeckerDeGrootMarschak (BDM) mechanism, the second-price auction, and the random nth-price auction in the measurement of private willingness-to-pay and willingness-to-accept for a pure public good. Our results show that the endowment effect...

In repeated-round auction mechanisms with endogenous market-clearing prices, i.e. when prices depend on submitted bids, the assumption of independent private values that underlines the property of incentive-compatibility is to be brought into question; even if these mechanisms provide active...

This paper proposes three analyses of the tradeoff mechanism between ecotax and carbon credit. Our wish is to compare the ecotax level with the carbon credit price, subject to the minimization of the cost inherent to emissions. We redefine the calculus equations of the firm profit, in which we...

We propose a dynamic graph-theoretic model for ecosystem management as a control over networked system composed of target nodes and unmarked nodes. The network is represented by a complete graph, in which all vertices are connected by a unique edge. Target nodes are attracted by the objective...

Agents face an ambiguous risk of biodiversity survival as well as ambiguous expected losses from its extinction. As a collectivity, agents are faced with the option of privately funding the protection of biodiversity for biomedical research. We propose two evolutionary models of threshold public...

We model the interactions between the management mode and costs of water services in order to compare their performances and pricing. We estimate those models on French panel data. We find that the choice by the local authority depends on the service costs and characteristics. There is no...

We model the interactions between management regimes (municipal vs. delegated) and operating costs of water supply services in order to compare their performance and pricing. We estimate the models from panel data in France. We show that the choice between management regimes at the local...

We analyze the contract-based relationship between a local community and a private operator in charge of a water utility. An important feature of the regulation model is the existence of water network losses that may reduce the operator's cost. We derive solutions to the optimal contract both...
