Do American and European industrial organization economists differ?

This paper compares results from two surveys among American and European industrial organisation (IO) economists on various IO and broader economic issues. Although differences between the two groups are generally rather small, some systematic differences seem to exist. These differences are more pronounced when judgments about the efficacy of government policies and the workings of the market are concerned than when judgments about methodology and 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 allocate resources than their European counterparts.
