Do American and European industrial organization economists differ?

This paper compares results from two surveys among American and European in dustrial organisation (IO) economists on various IO and broader economic is sues. Although differences between the two groups are generally rather smal l, some systematic differences seem to exist. These differences are more pr onounced when judgments about the efficacy of government policies and the w orkings of the market are concerned than when judgments about methodology a nd the present and future state of the IO field are concerned. American IO economists tend to exhibit more confidence in the market's capability to al locate resources than their European counterparts.
