Abstract:
In economics, choice or behavior is considered as a result of utility optimization. However, there’s much theoretical and experimental evidence that shows human beings suffer from decision-making and judgment errors. This research aiming at examining the relationship between post-choice attitude changes and framing effects as the two instances of those errors designed and implemented a 2 by 2 between-subject lab experiment. The subjects were randomly assigned to one of these four groups. The two treatment groups made their decision after they rated the objects one time and the two control groups did this after they evaluated the objects two times. Another intervention was to manipulate subjects’ object endowment. The results first shows that subjects in the treatment groups significantly modified their preferences compared to the control groups. The results also reveals that the main hypothesis, framing effects reduces post-choice attitude change, is confirmed at 10% significance level such that those whose choices were framed changed their attitudes less than those whose choices were not framed
