University of Bonn (Rheinische Friedrich-Wilhelms-Universität Bonn)
Bonn is one of the large universities in Germany, with around 36,000 students, 550 professors, 6,500 other staff staff. It offers a wide disciplinary spectrum comprising some 200 different degree programmes, from Agricultural Science to Tibetan Studies. This diversity is what characterizes Bonn as a full-range university with a strong international orientation. In many international university rankings Bonn is placed among the 100 best universities in the world.Its academic and research profile features internationally renowned specializations in the fields of Mathematics, Physics/Astronomy, Economics, Chemistry, Pharma Research, Biosciences, Genetic Medicine, Neurosciences and Philosophy/Ethics. Other disciplines, such as Geography and Law, are of outstanding importance within the German research scene.
The Rheinische Friedrich-Wilhelms-Universität Bonn is rooted in a long tradition going back almost 200 years. It was founded in 1818 by Friedrich-Wilhelm III, the Prussian king whose name it bears. Imbued with the spirit of Wilhelm von Humboldt, the university quickly joined the circle of Germany's most distinguished universities and became a major pole of attraction for leading scholars as well as students.The list of famous professors ranges from the astronomer Friedrich Wilhelm Argelander (1799-1875), through the chemist August Kekulé von Stradonitz (1829–1896) and political economist Josef Schumpeter (1883–1950) to the philologist Ernst Robert Curtius (1886–1956) and the theologists Karl Barth (1886–1968) and Joseph Ratzinger (born 1927), now Pope Benedict XVI. Bonn's best-known students include Heinrich Heine, Karl Marx, Friedrich Nietzsche, and Konrad Adenauer.
The university is proud of a long list of award-winning scientists and scholars, with about twenty Leibniz Prize winners and around thirty ERC grantees. In the last three decades two professors have received the Nobel Prize: Wolfgang Paul (for Physics, 1989) and Reinhard Selten (for Economics, 1994). (Source: University of Bonn)
To identify the best possible outcome, decision makers require information. In this video, SI CHEN explores information acquisition strategy and seeks to pinpoint when and why decision makers conclude that they have done sufficient research. In a laboratory experiment, decision makers are paired with receivers who, though affected by the decision, can only passively observe it. Decision makers have access to information which helps them to learn each option's outcomes for the receivers, while they know which option would benefit themselves. Combining the experimental outcomes with a theoretical model, Chen observes that decision makers tend to cease looking for more information when they come across information supporting a selfish behavior, but tend to continue and "search for excuses" to behave selfishly when this is not the case. Highlighting the decision makers' autonomy in information acquisition, the work shows that further research on information acquisition strategy will play a key role in our understanding of decision making.
