In this paper we provide existence and uniqueness results for the solution of BSDEs driven by a general square integrable martingale under partial information. We discuss some special cases where the solution to a BSDE under restricted information can be derived by that related to a problem of a BSDE under full information. In particular, we provide a suitable version of the Föllmer-Schweizer d...

Information acquisition in financial markets is analyzed in an integrated model of information and portfolio choice. Asset returns are assumed to be gamma distributed and signals to be Poisson. A simultaneous rational expectations equilibrium in asset and information markets does exist under fully revealing prices. It entails a strictly positive amount of acquired signals if markets are large, ...

The econophysics approach to socio-economic systems is based on the assumption of their complexity. Such assumption inevitably leads to another assumption, namely that underlying interconnections within socio-economic systems, particularly nancial markets, are nonlinear, which is shown to be true even in mainstream economic literature. Thus it is surprising to see that network analysis of nanci...

This note provides a proper example for the channel of strategic complementarities we proposed in our 2000 paper "Information Acquisition in Financial Markets". As pointed out in Chamley (2007), our earlier example contained an error, which, once corrected, reveals that our example actually exhibits strategic substitutability in information acquisition.

The World Wide Web is the most popular information dissemination channel in the world. Such information space grows by an estimation of at least 10% every month. Many newspapers take the advantage to expand their services by providing real time electronic versions of news information on the Web in contrast to the traditional ‘‘ink-on-paper’’ newspapers. The timely financial news is very importa...
