Quorum and Turnout in Referenda

We analyze the effect of turnout requirements in referenda in the context of a group turnout model. We show that a participation quorum requirement may reduce the turnout so severely that it generates a “quorum paradox”: In equilibrium, the expected turnout exceeds the participation quorum only if this requirement is not imposed. Furthermore, a participation quorum does not necessarily imply a bias for the status quo. We also show that in order to induce a given expected turnout and avoid the quorum paradox, the quorum should be set at a level that is lower than half the target. Finally, we argue that a super majority requirement to overturn the status quo is never equivalent to a participation quorum. (JEL: D72)     

“Allochthones” in the Netherlands and Belgium

Schematically one can distinguish two traditions related to ethnic statistics in Europe. In France, Germany and most southern European countries, the dominant statistical categorisations merely distinguish individuals on the basis of their nationality. In contrast, most northern European countries have been producing data on the ethnic and/or foreign origin of their populations. Belgium is caught somewhere in between these two traditions. The French speaking part of Belgium tends to follow the French tradition of refusing ethnic categorisation, while the Flemish try to copy the Dutch model in distinguishing “allochthones” and “autochthones.” This contribution offers an analysis of the construction of ethnic categories as it has been undertaken in the Dutch context and (partially) imported in Belgium.

An integrative approach to assess environmental and economic sustainability in multi-tier supply chains

Abstract

Multi-tier supply chain sustainability is paramount to achieve corporate sustainability, due to the significant impacts from organisations beyond the focal firm boundaries and its direct suppliers. However, including environmental considerations within the dominant profit-centric logic of supply chain related decisions is prone to generate sustainability tensions. This work aims to support organisations address tensions between sustainability dimensions by adopting an integrative approach for sustainable supply chain management performance assessment thanks to an innovative eco-intensity based performance assessment method, which achieves a balanced consideration of environmental and economic performance in a weak sustainability perspective. The method, using primary data sourced from actual practice and featuring an indirect multi-tier approach with decentralised responsibilities across organisations, is applied to a case study of a machinery supply chain. The proposed integrative approach can support addressing sustainability tensions in the area of sustainable supply chain management, facilitate sustainable supplier evaluation and identify supply chain hotspots for operational improvement.
