As Director of the Capabilities Measurement Project, which draws on contributions from the Open University, LSE, Oxford and elsewhere I have to say that this is an interesting and exciting debate. Our focus has been on seeing what might happen when the capabilities approach is applied to welfare analysis in high income countries and the development of data that really does measurement freedoms in a way that is consistent with the methodological conventions that apply to sample surveys. The survey instruments we have developed over the five years or more are highly multi-dimensional and we have used them tolook at deprivation using latent class and regression techniques and find that the multi-dimensional is often an interesting and valuable complement to money based measured. For one thing, we are beginning to develop a sense of what opportunities and welfare outcomes are particularly comprised by low income, and what types of people are most affected. In a lower income country context, it would of be wrong to let policy of the income hook and our implementation of Sen's ideas do not overly stress indexation for the reason that Martin outlines. Given that we have invested in developing data that is highly multi-dimensional, we want to apply analysis tools that make use of this dimensional information.
