Abstract. We discuss a model of gradual coalition formation with positive externalities in which a leading country endogenously decides whether to negotiate multilaterally or sequentially over climate change. We show that the leader may choose a sequential path, and that the choice is determined by the convexity of the TU-game and the free-rider payoffs of the followers. Except in a few clearly defined cases, the outcome of the negotiation process is always the grand coalition, although the process may need some time.

Abstract. Rangeland economists have noted that people tend to pay far more for ranches and rangelands than can be justified by the potential income from livestock operations alone.

Abstract. More frequent drought is projected for California. As water supplies constrict, and urban growth and out-migration spread to rural areas, trade-offs in water use for agriculture, biodiversity conservation, fire hazard reduction, residential development, and quality of life will be exacerbated. The California Black Rail (Laterallus jamaicensis coturniculus), state listed as “Threatened,” depends on leaks from antiquated irrigation district irrigation systems for much of its remnant small wetland habitat in the north central Sierra Nevada foothills.

Abstract

Purpose
Title and URL mentions have recently been proposed as web visibility indicators instead of inlink counts. The objective of this study is to determine the accuracy of these alternative web mention indicators in the Spanish academic system, taking into account their complexity (multi-domains) and diversity (different official languages).
