Decision Making & Negotiations

We investigated two types of metaphors in stock market commentary. Agent metaphors describe price trajectories as volitional actions, whereas object metaphors describe them as movements of inanimate objects. Study 1 examined the consequences of commentators? metaphors for their investor audience. Agent metaphors, compared with object metaphors and non-metaphoric descriptions, caused investors to expect price trend continuance. The remaining studies examined preconditions, the features of a price trend that evoke agent vs. object metaphors.

In most marketing experiments, managerial decisions are not based directly on the estimates of the parameters, but rather on functions of these estimates. For example, many managerial decisions are driven by whether or not a feature is valued more than the price the consumer will be asked to pay. In other cases, some managerial decisions are weighed more heavily than others. The standard measures used to evaluate experimental designs (e.g., A-efficiency or D-efficiency) do not accommodate these phenomena.

Polyhedral methods for choice-based conjoint analysis provide a means to adapt choice-based questions at the individual-respondent level and provide an alternative means to estimate partworths when there are relatively few questions per respondent as in a web-based questionnaire. However, these methods are deterministic and are susceptible to the propagation of response errors. They also assume, implicitly, a uniform prior on the partworths.

The relation between emotion and rationality is assessed by reviewing empirical findings from multiple disciplines. Two types of emotional phenomena are examined—incidental emotional states and integral emotional responses—and three conceptions of rationality are considered—logical, material, and ecological. Emotional states influence reasoning processes, are often misattributed to focal objects, distort beliefs in an assimilative fashion, disrupt self-control when intensely negative but do not necessarily increase risk-taking.

We integrate the financial architecture into the theory of investment by building on two strands of literature: irreversible investment and debt pricing/capital structure. We extend the real options approach to investment, pioneered by Michael J. Brennan and Eduardo S. Schwartz (1985) and Robert McDonald and Daniel Siegel (1986), to allow for capital structure decisions under strategic debt service. We also draw insights from corporate debt pricing/capital structure literature, which focuses on leverage and security pricing after investment has already been made (Robert C.

We propose and test a new approach for modeling consumer heterogeneity in conjoint estimation based on convex optimization and statistical machine learning. We develop methods both for metric and choice data. Like hierarchical Bayes (HB), our methods shrink individual-level partworth estimates towards a population mean. However, while HB samples from a posterior distribution that is influenced by exogenous parameters (the parameters of the second-stage priors), we minimize a convex loss function that depends only on endogenous parameters.

Business leaders need bold strategies to stay relevant and win. In Big Think Strategy, Schmitt shows how to bring bold thinking into your business by sourcing big ideas and executing them creatively. With the tools in this book, any leader can overcome institutionalized small think the inertia, the narrow-mindedness, and the aversion to risk that block true innovation. Your reward? Big, bold, and decidedly doable strategies that excite your employees and leave your rivals scrambling.

This paper examines the preferences of advice seekers for human information sources. We focus on the case in which advice providers can be people with high or low technical expertise (high in technical knowledge) and/or socially connected (connected to many others). Somewhat contrary to intuition, information sources who are high on social connectivity are shown to be relatively more attractive for more innovative products. Consistent with this, a meta-analysis indicates that the correlation between knowledge and opinion leadership is indeed lower for more innovative products.

Ernst & Young hosted this 2007 roundtable with the goal of providing a better understanding of the challenges and best practices of using valuation analysis to support executive decisions. Panelists included Richard Ruback of the Harvard Business School, Trevor Harris of Morgan Stanley, Aileen Stockburger of Johnson & Johnson, Dino Mauricio of General Electric, Christian Roch of BNP Paribas, Ken Meyers of Siemens Corporation, and Charles Kantor of Lehman Brothers. Jeff Green of Ernst & Young moderated.
