Paradoxes of Online Investing: Testing the Influence of Technology on User Expectancies*
研究发现，在线投资技术会增强投资者的自我效能感，导致他们对财务回报和非金钱奖励产生过高期望，但实际表现却更差。
ABSTRACT At an increasing rate, individual investors are taking personal control over their financial destinies by investing their money online. Compared to offline do‐it‐yourself approaches, evidence suggests that investors exhibit lofty expectations and perform significantly worse after going online. However, little is understood about the mechanisms fueling expectancies, the role technologies play in their formation, or how technologies shape investment decisions. Therefore, this article explores the paradoxical nature of online investing technologies, which can give rise to a heightened state of conviction in one's capability to invest successfully. Drawing on Social Cognitive Theory, the concepts of encapsulation and combination are introduced to develop a research model describing how functional and technical self‐efficacy judgments independently and collectively shape and influence outcome expectancies. The results suggest that perceptions about what one can accomplish through online investing technologies can lead investors to exaggerate their capabilities, which, in turn, produces elevated expectancies of financial payoffs and nonmonetary rewards. These findings carry important implications. In tasks requiring both computing and functional skills, the principals of encapsulation and combination highlight the importance of comprehensively capturing self‐efficacy beliefs across skill domain boundaries. Moreover, online investing represents a paradoxical case that challenges the traditional assumption that fostering a robust sense of efficacy represents a purely noble enterprise. In fact, strong self‐efficacy beliefs can prove counterproductive, leading to severe, irreversible, and unintended consequences. Going forward, these discoveries provide a solid foundation to enhance systems designs and facilitate a deeper understanding of user psychology.
