In Hypothesis 4 we predicted that the consumers' perceived sacrifice is negatively related to their willingness to accept mobile advertising. Our study supported this hypothesis, as there was a strong negative path (β= -.32) between perceived sacrifice and the willingness to accept mobile advertising. Also, Hypothesis 5 was supported, as the consumers' trust in privacy and the laws regulating mobile advertising were positively related to their willingness to accept mobile advertising (β= .11). However, this relationship was relatively weak, which implies that consumers do not consider these issues very important.
