For any finite word w on a finite alphabet, we consider the basic parameters Rw and Kw of w defined as follows: Rw is the minimal natural number for which w has no right special factor of length Rw and Kw is the minimal natural number for which w has no repeated suffix of length Kw. In this paper we study the distributions of these parameters, here called characteristic parameters, among the wo...

In two experiments on the choice of consumer goods, the estimated marginal willingness to pay for food are found to be lower in the survey version with cheap talk. Our test can be seen as a test of hypothetical bias. This implies we cannot reject the hypothesis of a hypothetical bias for marginal WTP in choice experiments. JEL classification: C91, Q13

When Cubitt, Munro and Starmer (2004) presented their new experimental investigation of preference reversal, they pointed out that their test results cannot be explained by any of the best-known explanations proposed by economists and psychologists. In this paper we propose a model based on lotteries qualities to explain these new test results. JEL classification: D80.

A decision maker tests whether the gradient of loss function evaluated at a judgmental is zero. If test does not reject, action decision. rejects, sets equal to boundary rejection region. This statistical rule admissible and conditions on sample realization. The confidence level reflects maker’s aversion uncertainty. applied problem asset allocation.

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

Mutual information (MI) is a robust nonparametric statistical approach for identifying associations between genotypes and gene expression levels. Using the data of Problem 1 provided for the Genetic Analysis Workshop 15, we first compared a quantitative MI (Tsalenko et al. 2006 J Bioinform Comput Biol 4:259-4) with the standard analysis of variance (ANOVA) and the nonparametric Kruskal-Wallis (...

Extraction of positive and negative ions from a saddle antenna radio-frequency surface plasma source (SA RF SPS) is considered. Several versions of new plasma generators with different antennas and magnetic field configurations were tested in the small Test Stand. The efficiency of positive ion generation in plasma has been improved up to 80 times from 2.5 mA/cm kW to ~0.2 A/cm per 1 kW. For ce...
