Abstract
This paper examines the way in which the distributional impact of projects has
been treated in the cost±bene®t analysis literature. It is suggested that excessive emphasis
has been given to the estimation of distribution weights in the context of single ®gure
measures of project worth and that more attention should be paid to estimation of the
distribution e ects themselves. If projects really are to have some impact on poverty it is
important that some attempt is made to measure what that impact is. Such an attempt
requires both systematic measurement of direct income e ects as well as the possibility of
measuring indirect e ects where these are expected to be important. An approach is
suggested in which direct measurement of income e ects can be adjusted using shadow
price estimates to determine indirect income e ects. The approach is illustrated with the
example of a district heating project in the Republic of Latvia.
