ABSTRACTCompared to other social sciences, it appears economists enjoy overwhelming influence in policy debates. What are the ethical concerns that should bear upon the exercise of such voice? Two forms of conflict of interest are explored here: funding sources may undermine objectivity in framing the research agenda as well as through the better-known route of influencing research outcomes. What questions get asked or ignored, and the methodological approach that economists choose, may be influenced by funders. Considerations of personal advancement may (...) influence how, when and what research is disseminated. The absence of debate on accountability of economists-as-advisors is worrying. Self-regulatory processes are needed so that power is exercised with greater responsibility. (shrink)
