Positive mood can affect a person's tendency to gamble, possibly because positive mood fosters unrealistic optimism. At the same time, unexpected positive outcomes, often called prediction errors, influence mood. However, a linkage between positive prediction errors-the difference between expected and obtained outcomes-and consequent risk taking has yet to be demonstrated. Using a large data se...

This paper examines the effects of hedging activities and executive compensation on firm value by incorporating the endogenous relationship between the two managerial decisions for a sample of U.S. oil and gas producers. Theories of hedging based on market imperfections imply that hedging should increase market value of firms. Likewise, the design of executive risk-incentive compensation is to ...

Agency theory posits that debt-like compensation (such as defined-benefit pensions and other deferred compensation) aligns managerial interests more closely with those of debtholders and reduces the agency cost of debt. Consistent with theory, we find that a higher CEO relative leverage, defined as the ratio of the CEO's inside leverage (debt-toequity compensation) to corporate leverage, is ass...

background this quantitative explanatory study was designed to explain the relationship between hiv/aids risk-taking behaviors among african american women and their knowledge surrounding hiv/aids. more specifically, the research considers whether knowledge alone was sufficient to alter african-american women’s risk-taking behaviors regarding hiv/aids. objectives this study was designed to inve...

CEOs and their management teams decide how much a firm will spend on IT. Though managers make IT spending decisions with the intent of generating value, such benefits are risky and not guaranteed (Dewan et al. 2007). While CEOs may perceive that IT spending could translate into competitive advantage and increase productivity, they also realize that IT expense will reduce current net income and ...

Article history: Received 17 September 2013 Received in revised form 1 March 2014 Accepted 11 March 2014 Available online 19 March 2014 Most studies consider chief executive officer (CEO) turnover from the firm's perspective. In this paper, I suggest that the labor market conditions for CEOs affect turnover outcomes. I use CEOs' positions on corporate executive and director networks to assess t...

1-wt% Pd-CeO(2) catalysts were prepared by co-precipitation of Pd nanoparticles with ceria (Pd@CeO(2)-CP), by a microemulsion procedure (Pd@CeO(2)-ME), and by normal impregnation of Pd salts (Pd/CeO(2)-IMP) in order to test the concept that Pd-CeO(2) catalysts could be more stable for the water-gas-shift (WGS) reaction when the Pd is embedded in CeO(2). Initial WGS rates measured at 250 degrees...

PURPOSE Social influence is prominent across the lifespan, but sensitivity to influence is especially high during adolescence and is often associated with increased risk taking. Such risk taking can have dire consequences. For example, in American adolescents, traffic-related crashes are leading causes of nonfatal injury and death. Neural measures may be especially useful in understanding the b...

Although immature cognitive control, subserved by late-developing prefrontal regions, has been proposed to underlie increased risk taking during adolescence, it remains unclear what patterns of PFC activation represent mature brain states: more or less activation? One challenge to drawing cogent conclusions from extant work stems from its reliance on single-time point neuroimaging and cross-sec...

According to the dual systems perspective, risk taking peaks during adolescence because activation of an early-maturing socioemotional-incentive processing system amplifies adolescents' affinity for exciting, pleasurable, and novel activities at a time when a still immature cognitive control system is not yet strong enough to consistently restrain potentially hazardous impulses. We review evide...
