The standard state-spaces of asymmetric information preclude non-trivial forms of unawareness (Modica and Rustichini, 1994, Dekel, Lipman and Rustichini, 1998). We introduce a generalized state-space model that allows for non-trivial unawareness among several individuals, and which satisfies...

This paper extends Li (2008b) to the multi-agent environment, where players reason about each other's awareness as well as knowledge, subject to their own awareness constraints. I characterize the interactive knowledge hierarchies under unawareness, which significantly differ from those in the...

We build on the imperfection of intellectual property rights as the central motivation for the organization of firms. There are several characteristics specific to a theory of the firm grounded on the absence of intellectual property rights: monetary incentive schemes arise naturally as a...

Modern underground space planning knowledge sharing no longer depends on face-to-face meetings, lectures or phone calls only. The conventional read-only Web 1.0 designed by HTML helps us know about the World wide underground space planning. Nevertheless, during the era of Web 1.0, online users...

Awareness structures by Fagin and Halpern (1988) (FH) feature a syntactic awareness correspondence and accessibility relations modeling implicit knowledge. They are a flexible model of unawareness, and best interpreted from a outside modeler's perspective. Unawareness structures by Heifetz,...

Problem Definition: This paper studies the information-sharing strategy for a retail platform on which multiple competing sellers distribute their products. Academic/Practical Relevance: Due to the rapid growth of retail platforms in recent years, information sharing has become an increasingly...

Recently, the maximum entropy principle has been applied to explain the evolution of complex non-equilibrium systems, such as the Earth system. I argue that it can also be fruitfully deployed to reconsider the classical treatment of entropy in economics by Georgescu-Roegen, if the growth of...

Users of social, economic, or medical networks share personal information in exchange for tangible benefits, but may be harmed by leakage and misuse of the shared information. I analyze the effect of enhancing privacy in the presence of two opposing forces: network effects and informational...

Because uncertainties around innovative technologies resolve over time, investments in such technologies are often made in stages so that organizations can use the knowledge gained from earlier stages to decide the next step. Previous studies usually assume that once some uncertainty is...

Under which circumstances do oligopolists have an incentive to share private information about a stochastic demand or stochastic costs? We present a general model which includes virtually all models of the existing literature on information sharing as special cases. The analysis reveals that in...
