The critical discount factor as a measure for cartel stability?

This paper considers the stability of tacit collusion in price setting duopolies with repeated interaction. The minimum discount factor above which tacit collusion can be sustained in a subgame perfect equilibrium is called the critical discount factor δ*. In addition, δ* is often used as an intuitive measure for the stability of a tacit cartel, assuming that a collusive equilibrium is more difficult to sustain when δ* increases. However, according to standard theory the distance δ − δ* between the actual and the critical discount factor does not matter for stability as long as δ > δ*. This paper contributes experimental evidence that supports the intuitive idea that a larger critical discount factor makes collusion a less likely outcome.

Critical natural capital revisited: Ecological resilience and sustainable development

The maintenance of critical natural capital is an important objective of sustainable development. Critical natural capital represents a multidimensional concept, as it mirrors the different frameworks of various scientific disciplines and social groups in valuing nature. This article revisits the concept of critical natural capital and examines its relation to the concept of ecological resilience. I propose that ecological resilience can help a great deal in specifying the ‘ecological criticality’ of specific renewable parts of the natural capital. More specifically, I suggest that the degree of ecological resilience is inversely related to the degree of threat ecosystems are prone to. The concept of ecological resilience may complement other measures, such as integrity or vulnerability, in estimating the degree of threat specific ecosystems are exposed to. The empirical estimates of ecological resilience add a further criterion in order to build a comprehensive and clear conception of critical natural capital.
