Imposing a minimum quality standard (MQS) is conventionally regarded as harmful if firms compete in quantities. This, however, ignores its possible dynamic effects. We show that an MQS can hinder collusion, resulting in dynamic welfare gains that reduce and may outweigh the static losses which...

Imposing a minimum quality standard (MQS) is conventionally regarded as harmful if firms compete in quantities. This, however, ignores dynamic effects. We show that an MQS can hinder collusion, resulting in dynamic welfare gains that reduce and may even outweigh the usual static losses. Verdicts...

Traditional power indices are not suited to take account of explicit preferences, strategic interaction, and particular decision procedures. This paper studies a new way to measure decision power, based on fully specified spatial preferences and strategic interaction in an explicit voting game...

The indirect evolutionary approach integrates forward-looking evaluation of opportunities and adaptation in the light of the past. Subjective motivation determines behaviour, but long-run evolutionary success of motivational types depends on objective factors only. This can justify intrinsic...

This paper proposes a unified framework that integrates the traditional index-based approach and the competing non-cooperative approach to power analysis. It rests on a quantifiable notion of ex post power as the (counter-factual) sensitivity of the expected or observed outcome to individual...

This article replies to the claim that preference-based power indices are impossible and that preferences should be ignored when assessing actors’ influence in different interactions (Braham and Holler [2005] ‘The Impossibility of a Preference-based Power Index’, Journal of...
