The Tamagawa number conjecture of Bloch and Kato describes the behavior at integers of the L-function associated to a motive over Q. Let f be a newform of weight k ≥ 2, level N with coefficients in a number field K. Let M be the motive associated to f and let A be the adjoint motive of M . Let λ be a finite prime of K. We verify the λ-part of the Bloch-Kato conjecture for L(A, 0) and L(A, 1) wh...

We study how the predictive power of level-k models changes as we perturb the classical beauty contest setting along two dimensions: the strength of the coordination motive and the information symmetry. We use a variation of the Morris and Shin (2002) model as the unified framework for our study, and find that the predictive power of level-k models varies considerably along these two dimensions...

When people learn aseries of actions of a character, their memory is strongly influenced, we suggest, by beUefs about that character's motives. Motives serve as schema for deciding the meaning of the actions, their importance, and their interconnections. In two experiments, subjects read and later remembered some dull activities of a character. Experimental subjects knew what this character was...

What is the reason for acquisitions? Till now, strategies related to the daily operations of the firm like increased sale, reduced cost or managerial ambitions have been the prevalent motive. However, a new dynamic motive, the competence explanation is emerging. The purpose of this paper is to develop the existing typology on acquisition motives with a combined approach of competence, resource ...

How many positive claims should be used to produce the most positive impression of a product or service? This article posits that in settings where consumers know that the message source has a persuasion motive, the optimal number of positive claims is three. More claims are better until the fourth claim, at which time consumers’ persuasion knowledge causes them to see all the claims with skept...

Affect regulation models of alcohol use posit individuals use alcohol to modify mood states. Importantly, these models hypothesize that individual differences in coping motives for drinking moderate the relation between drinking and negative moods. Despite consistently significant correlations among negative moods, coping motives, and alcohol involvement in numerous between-level studies, withi...

This paper studies the interaction between coordination and social learning in a dynamic regime change game. Social learning provides public information to which players overreact due to the coordination motive. So coordination affects the aggregation of private signals through players’ optimal choices. Such endogenous provision of public information results in inefficient herds with positive p...

We begin by thanking our discussants, Jiwoong Shin and K. Sudhir (2009) and Luís Cabral (2009), for their thoughtful comments on our research (Dubé, Hitsch, and Rossi 2009). Both commentaries focus on the stylized (“simple”) model in our article, which we used to motivate our more general empirical model. Shin and Sudhir solve a two-period Hotelling model. They find a U-shaped relationship betw...
