Much of the literature focuses on the incentives of presumably sophisticated informed agents to produce information, and not on the na¨ıve agents. However , unsophisticated agents are important aspects of financial markets and worth analyzing further. In this paper, we provide a theoretical perspe...

Efficient Prediction of Marsaglia-Zaman Random Number Generators

We show that the random number generator of Marsaglia and Zaman produces the successive digits of a rational -adic number. (The -adic number system generalizes -adic numbers to an arbitrary integer base .) Using continued fractions, we derive an efficient prediction algorithm for this generator.

We propose a family of methods for biomedical image time series registration based on Particle filtering. The first method applies an intensity-based information-theoretic approach to calculate importance weights. An effective second group of methods use landmark-based approaches for the same purpose by automatically detecting intensity maxima or SIFT interest points from image time series. A b...

Do charitable subsidies crowd out political giving ? The missing link between charitable and political contributions by Bar ı ş

In the United States, charitable contributions can be deducted from taxable income making the price of giving inversely related to the marginal tax rate. However, several other types of contributions such as donations to political organizations are not tax deductible. This paper investigates the spillover effects of charitable subsidies on political giving using five independent surveys of char...
