Evaluating the predictability of virtual exchange rates using daily data
Řanda, Martin ; Polák, Petr (advisor) ; Kukačka, Jiří (referee)
Virtual worlds have garnered the attention of researchers from various disci- plines and are viewed as particularly valuable to economists due to their open- ended design. In this thesis, we review a popular online multiplayer game's economy and focus on exchange rate predictability in a virtual setting as only a limited body of literature investigated this topic. The well-established unpre- dictability puzzle is addressed by exploiting a unique daily time series dataset using a vector autoregressive framework. Apart from a significant Granger- causal relationship between the virtual exchange rate and the player popula- tion, the system is shown to be less interconnected than expected. Furthermore, an out-of-sample exercise is conducted, and the forecasting performance of our models is examined in comparison to that of a simple no-change benchmark in the short term. Based on the evaluation methods used, the two measures of the virtual exchange rate are found to be somewhat predictable. We suggest two explanations for this inconsistency between the virtual and real-world exchange rates: data frequency and lack of complexity in the considered online economy.

Možnosti virtuálních světu pro komerční využití
Jergon, Roman ; Pour, Jan (advisor)
Thesis is concerned by virtual worlds and possibilities of their utilization other than are their original purposes. The objectives of this paper are to confront virtual worlds with mass media and their utilization. The author wants to show that virtual worlds are in many aspects similar to mass media. The author also shows possible utilization of virtual worlds for commercial companies, non-profit organizations, research and individuals. Work shows possible options for usage of virtual worlds together with option to cooperate with providers of the virtual world. This cooperation may take two forms. Content alternation means that providers of the virtual world change items or places inside the virtual world into the form desired by client. Providers may even sell their data about events inside the virtual world, thus clients may obtain unique data about human behavior and reaction to e.g. propagation campaign. Confrontation of virtual worlds with the mass media and describing possible utilizations that come from this confrontation, make content of this paper is original.
