New January 2014: "A Chance to Stay" - Modelling the Costs and Benefits of Foster Care

The average age for leaving home in the UK is 24i, yet vulnerable young people in care are often expected to live independently and leave care at 16, 17 or 18.

In a project for Action for Children Wales(AFC) we modelled the likely costs and benefits of "A Chance to Stay": a proposal to allow young people to stay with their foster carers up to the age of 21. To do this, we build a model that captured both the direct costs (payments to foster-carers, administration costs and so on) and the consequent effects on benefits paid and taxes received, and we illustrate the possible longer term effects of the scheme, under a variety of assumptions about its effect on employability and educational attainment. We show that under what seem reasonable assumptions, allowing young people to stay may well pay for itself in the medium term through increased taxes, and reduced social expenditures. The research was conducted jointly with Landman Economics and The University of Swansea, College of Human and Health Sciences.

Updated Summer 2012: ADRS Online - Massively parallel processing economic simulations online

Built for the ADRS consultancy, in one of our most technically challenging project yet, four multi-period on-line simulation models of the South African economy are now live.

July 2012: these models have now been significantly upgraded, with new tax and welfare benefit modules, improved poverty calculations, new income tax output modules and a completely rewritten output graphics system.

Two Easy Pieces

December 2009 Here are two little interactive teaching simulations:

Simulation Models of Ten African Countries

16th December 2009: Graham Stark been working on a wide ranging project organised by the United Nations University to help build microsimulation capacity in Africa. Models were built by teams from the countries themselves; Graham worked with the country teams to ensure the models were completed to a uniformly high standard and then build a sophisticated .

April 2009 : Virtual Worlds Microsimulation Models - Modelling Legal Aid

Virtual Worlds simulation models played a central part in modelling the extensions to eligibility to Legal Aid in Scotland. We produced detailed estimates of the likely costs of the reforms, and guidance on the optimal structure of the new contribution rates and income limits needed to maximise the amount of eligibility for legal aid given the available budget.

The model used is the latest in a family of microsimulation models of the Legal Aid systems of Scotland, Northern Ireland and England and Wales, using the Family Resources Survey as data. These model entitlements in great detail, and have sophisticated costs and takeup models which use disaggregated data on legal aid claims and payments, as well as unique optimisation routines which automatically find the best solutions for some combination of entitlements and costs.

New August 2012: Forecasting Social Care in Wales

In conjunction with Landman Economics, we've just completed a major piece of work for the Welsh Assembly Government on modelling the finance of social care.

This is the most technically sophisticated model we've ever been involved in; indeed, we believe it to be one of the most complex microsimulation projects ever undertaken anwhere in the world. It uses British Household Panel Survey (BHPS) data to model demand for social care under many possible financing systems for up to 20 years

New May 2012: Mefisto: Simulating Belgium!

Belgium may not have a government, but Mefisto, a collaboration between Virtual Worlds and the Universities of Leuven and Essex allows you to become the Belgian Chancellor.

Mefisto uses the Euromod system for its calculation back-end. This is the first time that a user-friendly interface has been succesfully built for the notoriously intractable Euromod system.

Modelling Affordability

16th October 2009 We've just completed a major piece of work for the Office of the Scottish Charities Regulator (OSCR) on modelling the ability the ability of beneficiaries to afford fees charged by charities.

You can read the papers here:

To accomplish this, we build a radical new form of simulation model which can be used to model the affordability of charges of all kinds on the general population.
