Much hope is put into the ‘‘four eyes principle’’ as an anti corruption device in many countries. However, as recent cases have shown, entire groups of decision makers can be corrupt as well. This paper reports on an experimental investigation of individual versus group decision making...

We experimentally examine the willingness to donate depending on whether “misery” has been randomly generated or self-inflicted by too high demands in bilateral negotiations. We find that randomness has a positive influence on the total amount of the donation. In the case of self-inflicted...

We examine the willingness to donate depending on whether “misery” is random generated or self-inflicted by too high demands in bilateral negotiations. We find that randomness has a positive influence on the total amount of donation. In case of self-inflicted “misery” we observe that the...

Alain Ledoux, who was one of over 6,000 chess players taking part in Bühren and Frank´s (2012) online Beauty Contest experiment, turned out to be the forgotten inventor of that game. We reconstruct the birth of the Beauty Contest. In section 1 of our note, its first two authors outline the...

In a beauty contest experiment with over 6,000 chess players, ranked from amateur to world class, we found that Grandmasters act very similar to other humans. This even holds true when they play exclusively against players of approximately their own strength. In line with psychological research...

We introduce a competitive framing in the mini-ultimatum game utilizing chess puzzles. Therein, our chess playing participants accept low offers significantly more often compared to a neutral framing. We conclude that in familiar competitive surroundings egoistic behavior is more acceptable.

<Para ID="Par1">The headwater of Yellow River Basin (HYRB) is crucial for the water resources of the whole basin in Northwest China. Based on the semi-distributed hydrological model “Soil and Water Assessment Tool” (SWAT), the spatiotemporal change trends of blue water and green water resources in the HYRB...</para>

Using the emergy analysis method, we conduct trend analysis of changes in the total emergy, input and output structure, various emergy indicators of agro-ecosystem in Hunan Province during the period 1999-2008. The results show that during the study period, total emergy input basically remained...

A three-dimensional (3D) hierarchically ordered mesoporous carbon–sulfur composite slice coated with a thin TiO2 layer has been synthesized by a low-cost process and investigated as a cathode for the lithium–sulfur batteries. The TiO2 coated carbon sulfur composite thin slice works as a...

We conducted an experimental study on social preferences using dictator games similar to Fehr et al. (2008). Our results show that social preferences differ between subjects who receive low-stakes monetary rewards for their decisions and subjects who consider hypothetical stakes. Our findings...
