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...

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...

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...

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...
