The standard, Bayesian account of rational belief and decision is often argued to be unable to cope properly with severe uncertainty, of the sort ubiquitous in some areas of policy making. This paper tackles the question of what should replace it as a guide for rational decision making. It defends a recent proposal, which reserves a role for the decision maker’s confidence in beliefs. Beyond being able to cope with severe uncertainty, the account has strong normative credentials on the main fronts typically evoked as relevant for rational belief and decision. It fares particularly well, we argue, in comparison to other prominent non-Bayesian models in the literature

Information processing filters out the noise in data but it takes time. Hence, low precision signals are available before high precision signals. We analyze how this feature affects asset price informativeness when investors can acquire signals of increasing precision over time about the payoff of an asset. As the cost of low precision signals declines, prices are more likely to reflect these signals before more precise signals become available. This effect can ultimately reduce price informativeness because it reduces the demand for more precise signals (e.g., fundamental analysis). We make additional predictions for trade and price patterns

We investigate how distraction affects the trading behavior of professional asset managers. Exploring detailed transaction-level data, we show that managers with a large fraction of portfolio stocks exhibiting an earnings announcement are significantly less likely to trade in other stocks, suggesting that these announcements absorb attention which is missing for the choice of which stocks to trade. Hence, attention constraints can be binding even among this elite group of traders. Finally, we identify two channels through which distraction hurts managers’ performance: distracted managers fail to close losing positions, partly explained by these managers displaying a stronger disposition effect, and incur slightly higher transaction costs

The impact of socially responsible corporate behavior on economic performance is a major preoccupation of managers today. This article explores the links between narrowly defined constructs: stakeholder orientation, environmental proactivity and profitability, from the perspectives of stakeholder theory and resource-based theory. We collected data on the food and beverage, and household and personal products industries. Using structural equation modeling, this paper makes two contributions. We found a negative link between companies simply having a higher stakeholder orientation and profitability. Importantly, however, environmental proactivity not only had a positive impact on profitability, but also appeared to mediate the relationship between stakeholder orientation and profitability. In other words, if a company is more environmentally proactive, it will be more attentive to a broad array of stakeholders, and this will in turn contribute positively to profitability
