American Sociological Association and the American Anthropology Association have a code of ethics. Similarly, the American Psychology Associationand the American Statistical Association both have guidelines for ethics. Does the American Economic Association need one for economists as well?
“Economists should maintain the highest degree of integrity in their professional work and avoid conflicts of interest and the appearance of conflict. Moreover, economists should disclose relevant sources of financial support and relevant personal or professional relationships that may have the appearance or potential for a conflict of interest in public speeches and writing, as well as in academic publications.”
I do not think an ethical code that asks economists to ‘maintain the highest degree of integrity’ will have much of an effect on behavior. First, most economists already know they should act with integrity. Second, what body would enforce that economists act with integrity. Without enforcement, the code would have little teeth. However, the AEA is made up of a small clique of economists, few of who would expel their peers (and friends) from being an economist.
On the other hand, compelling economists to disclose their financial interest could be useful. Almost every economist has their own homepage. The code could compel economists to include a link to a webpage which lists the sources from which the economists receive income. Again, enforcement could be a problem. The AEA could check that the webpage is updated annually for each of their members. It is unlikely, however, that the AEA would be able to verify the accuracy of these reports.
Thus, the code of ethics could promote more of a culture of disclosure among economists. For instance, upon all economists could be required to sign the code of ethics upon defending their dissertation. Thinking that the code of ethics will turn corrupt economists honest, however, is unrealistic. More likely, it will have a very marginal or no effect on economist behavior.
