3.5 Information Asymmetry Model Description
If the expected β6 coefficient for the disclosure model (M5) is confirmed, the equation M6 will be used to test whether HA reduces information asymmetry concerning the use of derivatives. In this model, the dispersion variable of analysts’ forecasts (DAFAi,t) is taken as a proxy for information asymmetry, in a procedure similar to that in Dadalt et al. (2002). Thus, DAFAi,t is regressed against DDIi,t and the other control variables, according to the equation:
