The Effect of Conference Calls on Analysts' Forecasts -- German Evidence

This study examines whether conference calls provide additional information to analysts. For a large sample of conference calls, hosted by German firms between 2004 and 2007, our results show that conference calls improve analysts' ability to forecast future earnings accurately. This suggests that additional information is released during conference calls. The reduction in forecast error is economically significant and larger in magnitude when compared to results for the US (Bowen <italic>et al</italic>., 2002). These findings are consistent with the notion that committing to additional disclosures is likely to yield greater effects in a less stringent disclosure system (Verrecchia, 2001). Since the majority of our sample firms conduct conference calls as closed calls, the evidence of this paper suggests that conference calls may contribute to an information gap between call participants and non-invited parties. Our findings should be of substantial interest to European regulators seeking to level the informational playing field for all investors.
