Dynamical representation of dominance relationships in the human rostromedial prefrontal cortex
Humans and other primates have evolved the ability to represent their status in the group's social hierarchy, which is essential for avoiding harm and accessing resources. Yet it remains unclear how the human brain learns dominance status and adjusts behavior accordingly during dynamic social interactions. Here we address this issue with a combination of fMRI and transcranial...

Unique equilibrium in contests with incomplete information
Considered are imperfectly discriminating contests in which players may possess private information about the primitives of the confiict, such as the contest technology, valuations of the prize, cost functions, and budget constraints. We find general conditions under which a given contest of this sort admits a unique pure-strategy Nash equilibrium. In particular, provided that all...

The youngest get the pill: ADHD misdiagnosis in Germany, its regional correlates and international comparison
Attention Deficit/Hyperactivity Disorder (ADHD) is a leading diagnosed health condition among children in many developed countries but the causes underlying these high levels of ADHD remain highly controversial. Recent research for the U.S., Canada and some European countries shows that children who enter school relatively young have higher ADHD rates than their older peers,...

Fictitious play in networks
This paper studies fictitious play in networks of noncooperative two-player games. We show that continuous-time fictitious play converges to Nash equilibrium provided that the overall game is zero-sum. Moreover, the rate of convergence is 1/T , regardless of the size of the network. In contrast, arbitrary n-player zero-sum games do not possess the fictitious-play property. As an...

Aggregate fluctuations in adaptive production networks
We study production networks where firms’ products can be described by a set of input and output characteristics, and links are formed only if the output characteristics of a seller match the input characteristics of a customer. We introduce a fully endogenous network formation model with monopolistically competitive firms, in which firms exit due to exogenous shocks, or the...

Time vs. state in insurance: experimental evidence from contract farming in Kenya
The gains from insurance arise from the transfer of income across states. Yet, by requiring that the premium be paid upfront, standard insurance products also transfer income across time. We show that this intertemporal transfer can help explain low insurance demand, especially among the poor, and in a randomized control trial in Kenya we test a crop insurance product which removes...

The economics of peace: can “Swiss” institutions do the job?
In the 5th edition of the UBS Center Public Paper Series, Dominic Rohner shows how conflict-torn countries can escape the vicious cycle of war and destruction. Much of the economics and political science literature on wars and conflict has focused on things that are hard for policymakers to change (natural resources, ethnic composition, and weather shocks). While this paper also...

The slippery slope of dishonesty
Recent experiments suggest that dishonesty can escalate from small levels to ever-larger ones along a 'slippery slope'. Activity in bilateral amygdala tracks this gradual adaptation to repeated acts of self-serving dishonesty.

Investigating the group-level impact of advanced dual-echo fMRI combinations
Multi-echo fMRI data acquisition has been widely investigated and suggested to optimize sensitivity for detecting the BOLD signal. Several methods have also been proposed for the combination of data with different echo times. The aim of the present study was to investigate whether these advanced echo combination methods provide advantages over the simple averaging of echoes when...

Brain network mechanisms underlying motor enhancement by transcranial entrainment of gamma oscillations
Gamma and beta oscillations are routinely observed in motor-related brain circuits during movement preparation and execution. Entrainment of gamma or beta oscillations via transcranial alternating current stimulation (tACS) over primary motor cortex (M1) has opposite effects on motor performance, suggesting a causal role of these brain rhythms for motor control. However, it is...

Free lunch and ride sharing: : a new business model for winter sport resorts
This paper proposes a new business model for winter sport resorts, by adopting a cluster approach. By following the guidelines for design research, we propose a new online service, which combines the notions of ridesharing and rebate. Ridesharing is often seen as a solution to reduce the number of cars in winter sport resorts, whereas the delivery of discount coupon has been used to...

Healthy lottery: : a design theory for a mobile system to increase compliance of individuals with diabetes
This article shows the preliminary results of an ongoing study to develop a system that financially rewards individuals with diabetes. Previous studies have already shown that monetary incentives appear to be the strongest motivator for older individuals with type II diabetes. Nonetheless, design criteria for a mobile service are not well established and there is no study available...

Check the temperature: : rapid assessment of common ground in startup teams
This research in progress aims at identifying a set of design guide-lines to perform rapid diagnostic of common ground among participants of a startup team and their coach. Previous studies have shown that teams with high common ground are more efficient. Nonetheless, no existing tool can rapidly monitor its progression and visualize it in a simple way to allow the coach to perform...

Service response to economic decline: : innovation actions for achieving strategic renewal
Thispaper develops process theory on how service firms deal with persistent economic decline and the practices they adopt to overcome it. It examines how a knowledge-based service activity— commercial archeology— attempts to overcome environmental constraints of increasing complexity and economic downturn, as it unfolded over an 8-year period.This longitudinal,multimethod field study...

What it takes to get proactive: : an integrative multilevel model of antecedents of personal initiative
Building upon and extending Parker, Bindl, and Strauss’s (2010)theory of proactive motivation, we develop an integrated, multilevel model to examine how contextual factors shape employees’ proactive motivational states and, through these proactive motivational states, influence their personal initiative behavior. Using data from a sample of hotels collected from 3 sources and over 2...

Sensemaking of organizational innovation and change in public research organizations
Purpose – The purpose of this paper is to examine through a sensemaking lens the transforming nature of scientists’ work role in public research organizations (PROs), resulting from organizational innovations in the form of collaborative culture. Design/methodology/approach – Based on a symbolic-functionalist theory of work role transition, the paper uses interview data from a case...
