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...

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...

The similarity between objects is a fundamental element of many learning algorithms. Most non-parametric methods take this similarity to be fixed, but much recent work has shown the advantages of learning it, in particular to exploit the local invariances in the data or to capture the possibly...

A standard model of the exploitation of a renewable resource by non-cooperating agents is considered. Under the assumption that the resource is sufficiently productive we prove that there exist infinitely many Markov-perfect Nash equilibria (MPNE). Although these equilibria lead to...

In this paper, we study and put under a common framework a number of non-linear dimensionality reduction methods, such as Locally Linear Embedding, Isomap, Laplacian Eigenmaps and kernel PCA, which are based on performing an eigen-decomposition (hence the name 'spectral'). That framework also...

The purpose of this study was to examine the role of country and technological intensity in the choice of compensation policies, and the influence of such policies on market performance and turnover in high and low technological intensity firms. Using a survey of 602 large firms in three...
