If each member of a group assigns a certain probability to a hypothesis, what probability should the collective as a whole assign? More generally, how should individual probability functions be merged into a single collective one? I investigate this question in case that the individual...

Recent studies in information economics demonstrated that asymmetric information existing between market agents induce a lost in efficiency as well as market failures. This paper aims to draw heavily from these theoretical intuitions in order to analyse the individual sports’ environment. The...

In a repeated game with private information, a perfect public equilibrium (PPE) can break down if communication is not necessarily simultaneous or if players can “spy” on each others’ information. An ex post perfect public equilibrium (EPPPE) is a PPE that is ex post incentive compatible...

Financial markets are to a very large extent influenced by the advent of information. Such disclosures, however, do not only contain information about fundamentals underlying the markets, but they also serve as a focal point for the beliefs of market participants. This dual role of information...

We conduct experiments of a cheap-talk game with incomplete information in which one sender type has an incentive to misrepresent her type. Although that Sender type mostly lies in the experiments, the Receiver tends to believe the Sender's messages. This confirms ``truth bias'' reported in...

The analysis covers 27 international organizations in the years 1950- 2001. From the first to the last year, staff increased at a compound average rate of 3.2 percent per annum. Since the number of member states rose by only 2.5 percent, the elasticity of staff to member states is larger than...

According to empirical evidence, extrinsic incentives often crowd out intrinsic motivation, thus reducing the effort choices of workers. This article presents a simple model illustrating how the introduction of monetary incentives causes a discontinuous reduction in worker effort as well as a...

We propose a quantum-like description of markets and economics. The approach has roots in the recently developed quantum game theory. Quantum Zeno paradoxes and noncomutative quantum mecanics are also discussed.

According to the standard definition, a Bayesian agent is one who forms his posterior belief by conditioning his prior belief on what he has learned, that is, on facts of which he has become certain. Here it is shown that Bayesianism can be described without assuming that the agent acquires any...

IT SEEMS APPROPRIATE TO ASK WHAT IS SPECIAL ABOUT INFORMATION AND INFORMATION TECHNOLOGY BEFORE ONE SETS OUT TO ANSWER THE QUESTION OF HOW INVESTMENTS IN INFORMATION INFRASTRUCTURE SHOULD BE VALUED AND REGULATED.THIS PROJECT THEREFORE DISCUSSES THE THEORETICAL AND PRACTICAL CONCEPTS UNDERLYING...
