The Model

You are about to feel what it is like to be the chancellor of the exchequer, to run the nation's economy - or rather the Virtual Economy - as you think fit.

To make any changes, use the drop-down menus - just select the value that is closest to what you want. When you are happy with your reforms, click the 'Run Model' button at the end.

The results come out as figures and graphs - so if using a slow link you might want to turn off your images.

If you are interested in further details, they can be found at the IFS.

 Budget Constraints
Instead of producing calculations for all our families, it is also possible to produce a Budget Constraint plot for one of the families. These graphs show how the net income of the family changes as the earnings of one of the family members change.

The system used here was originally developed by BizEd and The Institute for Fiscal Studies, with funding from The Nuffield Foundation. The MacroEconomic model and forecasts were provided by Oxford Economic Forecasting. Web development was by KB7.
