While indices, index tracking funds and ETFs have grown in popularity during then last ten years, there are many structural problems, tracking errors and biases inherent in index calculation methodologies and the legal/economic structure of ETFs, which raise actionable issues of "suitability" and "fraud" under US securities laws. This article contributes to the existing literature by: (a) introducing and characterizing the errors and biases inherent in "risk-adjusted" index-weighting methods and the associated adverse effects; (b) showing how these biases/effects reduce social welfare, and can facilitate harmful arbitrage activities; (c) introducing new theorems.

There is a lack of methodologically grounded and generally accepted regional competitiveness’ evaluation method in Latvia. Common feature of the research about nature of competitiveness is that competitiveness of a region depends on how high and sustainable the level of prosperity in the region is. The analysis of scientific literature showed, that most often synthetic indexes are used to evaluate competitiveness of a region. Methodology to evaluate regional competitiveness was developed and approbated in case of Latvia. To identify the most appropriate method for competitiveness index calculation, Regional Competitiveness Index (RCI) according to two different methods was calculated in the research. The results obtained were similar, but each of index calculation methods has its own advantages and disadvantages and the choice of the appropriate method will depend on the researcher's goals and objectives. Use of relative weights in index calculations affects the obtained results, therefore, necessity of relative weights must be economically justified. It was proven that regional competitiveness cannot be characterized by such simple indicators as GDP or GDP per capita. RCI shows the level of competitiveness of Latvia’s statistical regions, it is possible to compare regions in time and among each other. It allows to form regional development policy and strategy more reasonably.

The increase of data access capacity and data types of the power grid leads to a more complex and varied grid running environment. Hence, in order to guarantee the running security of the master station, an online monitoring and evaluation system based on index system for master station is proposed in this paper. It can construct a dynamic evaluation model and complete automated collection, analysis, scoring and evaluation of indexes by using specific index calculation methods. Moreover, this system can provide comprehensive interface display for evaluation results and achieve online alarming for the abnormal situations of the master station. This system offers a new and effective way to guarantee the safe and reliable running of the master station.
