This article demonstrates how a BI scheme can be designed to fulfill a set of stated objectives according to given priorities, such as redistribution, poverty prevention, work incentives, and so on. It provides a simple, illustrative model, with partial and full BIs set at proportions 25 percent and 50 percent respectively of mean income. It finds that there is a variety of potential levels for the partial BIs without increasing the standard rate of income tax. This offers a remarkable degree of flexibility. And it demonstrates that even fairly generous BI schemes are economically feasible in the UK.
