We argue that the strength of the relationship between income and happiness can be influenced by exposure to organizational practices, such as being paid by the hour, that promote an economic evaluation of time use. Using cross-sectional data…

Why do people give to others? One principal driver involves ones identity: who one is and how they view themselves. The degree to which identities are malleable, involve a readiness to act, and help make sense of the world have significant…

We analyze a new general representation for the Minimum Weight Steiner Tree (MST) problem which translates the topological connectivity constraint into a set of local conditions which can be analyzed by the so called cavity equations techniques.…

Three studies tested the hypothesis that when people receive persuasive messages, their perceptions of the information on which they base their attitudes can determine feelings of subjective ambivalence. Across studies, it is shown that when…

Most companies have more freedom than they imagine to organize their supply chains for maximum efficiency. By rethinking inventory control in terms of who owns the inventory at any point, where it should be located, and who controls it, managers…

We quantify the impact of social interactions and peer effects in the context of prescription choices by physicians. Using detailed individual-level prescription data, along with self-reported social network information, we document that…

In recent years, the electronics industry has made important improvements in social and environmental responsibility (SER) conformance among first-tier suppliers, due in part to the standardization of SER practices set forth in the Electronics…

Five experiments demonstrate that exposure to novel visual stimulus arrays of geometric shapes affects consumers’ real choices among products. The authors first demonstrate that exposure to variety arrays (arrays of differing shapes) increases…

Social interactions occur when agents in a network affect other agents’ choices directly, as opposed to via the intermediation of markets. The study of such interactions and the resultant outcomes has long been an area of interest across a wide…

Large collectives (e.g., organizations, political parties, nations) are seldom unitary players. Rather, they consist of different subgroups that often have conflicting interests. Nonetheless, negotiation research consistently regards…

I show that stock market shocks have important and lasting effects on the careers of MBAs. Stock market conditions while MBA students are in school have a large effect on whether they go directly to Wall Street upon graduation. Further, starting…

We suggest that the need to maintain a positive self-image motivates White Americans to conceive of racism as a phenomenon rooted in individuals instead of…

This paper examines whether firms manipulating their reported financial results make suboptimal investment decisions. We examine fixed asset investments for a large sample of public companies during the 1978-2002 period and document that firms…

We propose an approximation method for analyzing Ericson and Pakes (1995)-style dynamic models of imperfect competition. We define a new equilibrium concept that we call oblivious equilibrium, in which each firm is assumed to make decisions based…

Highly relational contexts can have costs as well as benefits. Researchers theorize that negotiating dyads in which both parties hold highly relational goals or views of themselves are prone to relational accommodation, a dynamic resulting in…

Severe flight to quality episodes involve uncertainty about the environment, not only risk about asset payoffs. The uncertainty is triggered by unusual events and untested financial innovations that lead agents to question their worldview. We…
