Aggregating labour supply and feedback effects in microsimulation

This paper extends behavioural microsimulation modelling so that third round effects of a policy change can be simulated. The first round effects relate to fixed hours of work, while second round effects allow for changes in desired hours of work at unchanged wages. These allow for endogenous changes to the distribution of wage rates resulting from the labour supply responses to tax changes. This is achieved using the concept of an aggregate ѳupply response scheduleҬ which identifies the extent to which average labour supply responds to a proportional change in wage rates. The third round effect is obtained after re-running a microsimulation model with a suitable modification to individuals' wage rates. The method is illustrated using the MITTS behavioural microsimulation model.

Maass-Jacobi Poincar\'e series and Mathieu Moonshine

Mathieu moonshine attaches a weak Jacobi form of weight zero and index one to each conjugacy class of the largest sporadic simple group of Mathieu. We introduce a modification of this assignment, whereby weak Jacobi forms are replaced by semi-holomorphic Maass-Jacobi forms of weight one and index two. We prove the convergence of some Maass-Jacobi Poincar\'e series of weight one, and then use these to characterize the semi-holomorphic Maass-Jacobi forms arising from the largest Mathieu group.Comment: 27 pages, minor correction

Religious actors, civil society, and the development agenda: The dynamics of inclusion and exclusion

This article uses the World Bank\u27s engagement with religious actors to analyse their differentiated role in setting the development agenda raising three key issues. First, engagements between international financial institutions (IFIs) and religious actors are formalised thus excluding many of the actors embedded within communities in the South. Secondly, the varied politics of religious actors in development are rarely articulated and a single position is often presented. Thirdly, the potential for development alternatives from religious actors excluded from these engagements is overlooked, due in part to misrecognition of the mutually constitutive relationship between secular and sacral elements in local contexts
