Decision Making & Negotiations

This paper studies the competition between Web 2.0 communities in a game theoretic framework. We model three important features of these institutions: (i) firms' content is usually user-generated; (ii) consumers' content preferences are governed by local network effects, and (iii) consumers have strong tendencies to multi-home. Our analyses reveal that ex-ante identical community sites can acquire differentiated market positions that spontaneously emerge from user-generated content.

Contingent capital (CC), which intends to internalize the costs of too-big-to-fail in the capital structure of large banks, has been under intense debate by policy makers and academics. We show that CC with a market trigger, in which direct stake-holders are unable to choose optimal conversion policies, does not lead to a unique competitive equilibrium, unless value transfer at conversion is not expected ex-ante. The "no value transfer" restriction precludes penalizing bank managers for taking excessive risk.

We consider a multi-period single product pricing problem with an unknown demand curve. The seller's objective is to adjust prices in each period so as to maximize cumulative expected revenues over a given finite time horizon; in so doing, the seller needs to resolve the tension between learning the unknown demand curve, and earning revenues by solving the dynamic optimization problem.

During the 2014 EPIC Conference, Allen Batteau and Robert J. Morais led a workshop entitled “Toward Conceptual, Methodological, and Ethical Standards of Practice in Business Anthropology.” This article summarizes the objectives and results of the workshop.

The paper investigates the long-run consequences of multichannel shopping on customers' spending. Using data from a major US catalog company which introduced an online channel, our results validate previous findings that multichannel customers spend more than mono-channel customers in the short run. However, the difference in spending dissipates over time with multichannel customers reverting to their regular consumption pattern in 3 years.

Shortfall aversion reflects the higher utility loss of a spending cut from a reference point than the utility gain from a similar spending increase, in the spirit of Prospect Theory's loss aversion. This paper posits a model of utility of spending scaled by a function of past peak spending, called target spending. The discontinuity of the marginal utility at the target spending corresponds to shortfall aversion.

We propose that an individual's regulatory focus moderates the significant role social network density — the degree of interconnectedness among a person's social contacts — plays in shaping life satisfaction. Evidence from Study 1 indicates that participants with high prevention effectiveness reported higher life satisfaction when they were embedded in a high-density network, whereas participants with low promotion effectiveness reported lower life satisfaction when they were embedded in a low-density network.

We develop a model to understand and predict customers’ observed multichannel behavior in a customer support setting.

In the wake of recent revelations about US involvement in torture, and widespread and seemingly-growing support of torture in the US, we consider how people judge the value of information gained from informants under coercion. Drawing on past work on confirmation biases and moral judgments, we predicted, and found, that American torture supporters are more likely than opposers to see coerced information as relatively valuable and necessary in a scenario describing the foiling of an al-Qaeda terrorist attack.
