What makes some entrepreneurs persist in their venture efforts while others quit? Self-efficacy has robustly been found to drive persistence, yet recent work suggests that affect, in particular entrepreneurial passion, may also enhance persistence. We empirically examine the possibility that the long-standing relationship between self-efficacy and persistence might be mediated by entrepreneurial passion. Using data from 129 entrepreneurs, we find that the self-efficacy to persistence relationship is mediated by passion for inventing and for founding but not by passion for developing firms. The passion of entrepreneurs appears to help explain the relationship between entrepreneurial self-efficacy and sustained entrepreneurial action
How can consumers be encouraged to take better care of public goods? Across four studies, including two experiments in the field and three documenting actual behaviors, the authors demonstrate that increasing consumers’ individual psychological ownership facilitates stewardship of public goods. This effect occurs because feelings of ownership increase consumers’ perceived responsibility, which then leads to active behavior to care for the good. Evidence from a variety of contexts, including a public lake with kayakers, a state park with skiers, and a public walking path, suggests that increasing psychological ownership enhances both effortful stewardship, such as picking up trash from a lake, and financial stewardship, such as donating money. This work further demonstrates that the relationship between psychological ownership and resulting stewardship behavior is attenuated when there are cues, such as an attendance sign, which diffuse responsibility among many people. This work offers implications for consumers, practitioners, and policy makers with simple interventions that can encourage consumers to be better stewards of public goods.
Psychological ownership, or the feeling that something is mine, has garnered growing attention in marketing. While previous work focuses on the positive aspects of psychological ownership, this research draws attention to the darker side of psychological ownership—territorial behavior. Results of five experimental studies demonstrate that when consumers feel psychological ownership of a target, they are prone to perceptions of infringement and subsequent territorial responses when they infer that another individual feels ownership of the same target. Potential infringers are held less accountable when they acknowledge ownership prior to engaging in otherwise threatening behaviors, and when they could not be expected to know that a target is owned, as it was not clearly marked. In addition, high narcissists are subject to a psychological ownership metaperception bias, and are thus more apt than low narcissists to perceive infringement. A multitude of territorial responses are documented for both tangible (coffee, sweater, chair, pizza) and intangible (a design) targets of ownership. Further, consumers infer the psychological ownership of others from signals of the antecedents of psychological ownership: control, investment of self, and intimate knowledge. Theoretical implications for territoriality and psychological ownership are discussed, along with managerial implications and areas for future research.
In this paper we focus on three fixed point theorems and an integral equation. Schaefer's fixed point theorem will yield a T -periodic solution of z(t) = a(t) + D(t, s)g(s, z(s)) ds 6, if D and g satisfy certain sign conditions independent of their magnitude. A combination of the contraction mapping theorem and Schauder's theorem (known as Krasnoselskii's theorem) will yield a T -periodic solution of z(t) = f(t, 4 t ) ) + D ( t , s)g(., 4 3 ) ) d.9 (0.2) L, if j defines a contraction and if D and g are small enough.We prove a fixed point theorem which is a combination of the contraction mapping theorem and Schaefer's theorem which yields a T-periodic solution of (0.2) when f defines a contraction mapping, while D and g satisfy the aforementioned sign conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
