Estimation of the environmental services values, represents a crucial element in the process of taking of decisions on environmental programs and policies to develop, as well as an orientation instrument for the implementation of production patterns and more sustainable consumption. From this...

In this paper, we study the incumbent's incentive to share its essential facility when there exist network effects. We show that without network effects, the incumbent will charge an access fee high enough to deter the entry. with network effects, however, the incumbent always has an incentive...

This paper introduces a tractable, structural model of subjective beliefs. Since agents that plan for the future care about expected future utility flows, current felicity can be increased by believing that better outcomes are more likely. On the other hand, expectations that are biased towards...
