The Lure of Authority: Motivation and Incentive Effects of Power

Fehr, Ernst ; Herz, Holger ; Wilkening, Tom

In: The American Economic Review, 2013, vol. 103, no. 4, p. 1325-1359

Authority and power permeate political, social, and economic life, but empirical knowledge about the motivational origins and consequences of authority is limited. We study the motivation and incentive effects of authority experimentally in an authority delegation game. Individuals often retain authority even when its delegation is in their material interest—suggesting that authority has...

The intrinsic value of decision rights

Bartling, Björn ; Fehr, Ernst ; Herz, Holger

In: Econometrica, 2014, vol. 82, no. 6, p. 2005-2039

Philosophers, psychologists, and economists have long argued that certain decision rights carry not only instrumental value but may also be valuable for their own The ideas of autonomy, freedom, and liberty derive their intuitive appeal - partly - from an assumed positive intrinsic value of decision rights. Providing evidence for the existence of this intrinsic value and measuring its size,...

Basal forebrain contributes to default mode network regulation

Nair, Jayakrishnan ; Klaassen, Arndt-Lukas ; Arato, Jozsef ; Vyssotski, Alexei L. ; Harvey, Michael ; Rainer, Gregor

In: Proceedings of the National Academy of Sciences, 2018, vol. 115, no. 6, p. 1352–1357

The default mode network (DMN) is a collection of cortical brain regions that is active during states of rest or quiet wakefulness in humans and other mammalian species. A pertinent characteristic of the DMN is a suppression of local field potential gamma activity during cognitive task performance as well as during engagement with external sensory stimuli. Conversely, gamma activity is...

Astrocytic and neuronal oxidative metabolism are coupled to the rate of glutamate–glutamine cycle in the tree shrew visual cortex

Sonnay, Sarah ; Poirot, Jordan ; Just, Nathalie ; Clerc, Anne-Catherine ; Gruetter, Rolf ; Rainer, Gregor ; Duarte, João M. N.

In: Glia, 2018, vol. 66, no. 3, p. 477–491

Astrocytes play an important role in glutamatergic neurotransmission, namely by clearing synaptic glutamate and converting it into glutamine that is transferred back to neurons. The rate of this glutamate–glutamine cycle (VNT) has been proposed to couple to that of glucose utilization and of neuronal tricarboxylic acid (TCA) cycle. In this study, we tested the hypothesis that glutamatergic...

Malaria infected red blood cells release small regulatory RNAs through extracellular vesicles

Babatunde, Kehinde Adebayo ; Mbagwu, Smart ; Hernández-Castañeda, María Andrea ; Adapa, Swamy R. ; Walch, Michael ; Filgueira, Luis ; Falquet, Laurent ; Jiang, Rays H. Y. ; Ghiran, Ionita ; Mantel, Pierre-Yves

In: Scientific Reports, 2018, vol. 8, no. 1, p. 884

The parasite Plasmodium falciparum causes the most severe form of malaria. Cell communication between parasites is an important mechanism to control population density and differentiation. The infected red blood cells (iRBCs) release small extracellular vesicles (EVs) that transfer cargoes between cells. The EVs synchronize the differentiation of the asexual parasites into gametocytes to...
