Opportunistic propensity hinders commitment to acts in conditions of forced compliance and compliance without pressure

The psychosocial literature contains empirical evidence of the effects of personality variables on commitment to acts. The association of economic opportunism was explored with respect to postexperimental attitude change, intentions, and intrinsic motivation of individuals (N = 132) toward acts with either forced compliance or compliance without pressure. In conditions of commitment and compliance without pressure, both intention and intrinsic motivation decreased as economic opportunism increased, while in conditions of commitment and forced compliance, intention increased as economic opportunism increased. Attitude change and economic opportunism did not appear to be associated in any experimental condition. These findings suggest that tendency to noncooperativeness predisposes to reduced concern for consistency and compliance with performed acts.

Social embeddedness and economic opportunism: a game situation

According to Evolutionary Game Theory, multiple exchanges with partners are necessary to foster cooperation. Multiple exchanges with partners tend to enhance the good experience of the partners and the predictability of their behaviour and should therefore increase cooperativeness. This study explored whether social embeddedness, or the preference for close and stable social relationships, a variable which tends to increase multiple exchanges, is associated with more cooperative attitudes; and whether social embeddedness increases cooperative behavior towards unknown partners in a game situation. The first study, with 169 undergraduates, indicated that social embeddedness (preference for close and durable social relations) was negatively associated with opportunistic attitudes. The second study had a sample of 60 undergraduates playing a Trust Game with unknown partners and showed that self-reported social embeddedness was positively correlated with scores for cooperative economic behavior towards the partners. These results highlight the relationships of social embeddedness with cooperative attitudes and behaviour.

Preference for Non-Cooperative Economic Strategies is Associated with Lower Perceived Self-Efficacy, Fewer Positive Emotions, and Less Optimism

The goal was to investigate the association of economic opportunism with self-efficacy, optimism, and positive emotion. It was hypothesized that economic opportunists should experience lower self-efficacy, less positive thinking, and less optimism. Study 1 (N = 206) showed that economic opportunism was negatively correlated with self-efficacy, optimism, and positive affect, and positively correlated with negative affect. Study 2 (N = 128) indicated that individuals reporting higher self-efficacy were less likely to defect on their counterparts in a game situation. These findings show the negative association of opportunistic propensity with self-efficacy and positive emotions. Implications for experimental research on economic opportunism and positive emotions are discussed.
