| Summary: | 碩士 === 國立臺北大學 === 會計學系 === 92 === In recent years, the conference call becomes a prevalent way to communicate to financial analysts. This study is to investigate whether the absolute forecast error and forecast error of the forecast released by the conference call are “better” than those released by none-conference call, and to know the economic role played by the conference call. I adopted multiple regression analyses to test the absolute forecast error and forecast error of the conference call and none-conference call, including company size, time horizon, earnings variable, market risk, industry, debt ratio in the regression model as control variables. The empirical results find that no matter in annual sales, net earnings before tax, net earnings after tax, and earnings per share, the absolute forecast error and forecast error of the conference disclosed by the conference call are “better” than those disclosed by none-conference call .
