1. Information and financial markets
Sammanfattning : The results in this thesis are consistent with the hypotheses that: 1) the incomplete dissemination of information across investors helps in explaining the occurrence and the persistence of cross-sectional stock return anomalies, 2) the properties of the investor base of a stock have implications for the informativeness of the stock's price and 3) a greater quantity of firm disclosure places less sophisticated investors at an information disadvantage. Overall, the thesis provides new empirical evidence about the role of information in financial markets. LÄS MER
2. Optimal stopping, incomplete information, and stochastic games
Sammanfattning : This thesis contains six papers on the topics of optimal stopping and stochastic games. Paper I extends the classical Bayesian sequential testing and detection problems for a Brownian motion to higher dimensions. We demonstrate unilateral concavity of the cost function and present its structural properties through various examples. LÄS MER
3. Selfish Dynamic Spectrum Access in Multichannel Wireless Networks : Complete and incomplete information analysis
Sammanfattning : The increasing popularity and widespread deployment of wireless data systems fuel the increasing demand for more spectrum. On the other hand, various studies measuring spectrum utilization show that there is a huge variation in spectrum utilization at different times and locations. LÄS MER
4. Coordinated MultiPoint Transmission with Incomplete Information
Sammanfattning : The demand for higher data rates and efficient use of various resources has been an unquenchable thirst across different generations of cellular systems, and it continues to be so. Aggressive reuse of frequency resources in cellular systems gives rise to intercell interference which severely affects the data rate of users at the cell-edge. LÄS MER
5. Mapping incomplete relational data : networks in ecology & evolution
Sammanfattning : We live in an interconnected world full of complex systems that cannot be understood simply by analyzing their components. From how genes regulate biological functions to the distribution of life on Earth, we need methods that can analyze systems as a whole. LÄS MER
