THE ECONOMIC EFFICIENCY OF FIELD CROPS CULTIVATION IN SOUTH ROMANIA: TRENDS AND ACTIONS FOR IMPROVEMENT

The South of Romania experiences important climate changes, with importanteffects over the traditional crops, as wheat, sunflower, and especially maize, affected verynegative by the summers’ draught. These evolutions leaded to a diminution of the agriculturalfarms economic efficiency in this area. Given this situation, the farmers had to introduce newfield crops in order to improve the agricultural exploitations profitability. This paper presentsan analysis of the evolution in the area cultivated with traditional crops vs. industrial cropsand their comparative economic efficiency. Also, the unequal competition with the Americangenetically modified imports and the commodities’ market underdevelopment are pointed out,as the necessary actions to improve the situation of the farmers engaged in traditional cropscultivation.Efficiency analysis, traditional crops, industrial crops

Measurement of National Non-Visible Wealth through Intellectual Capital

The economy of knowledge requires measures of national wealth that take into account aspects not contemplated by GDP, in order to portray the situation of a country more truthfully. In this paper, we use a new model to measure the intellectual capital of nations, adapted from microeconomics. It is based on the observation of hidden capital as implicit generator of long-term wealth, considering not only sustainability and social wellbeing, but also intangible assets such as human development, economic structure, international trade, foreign image and innovation. This empirical study reveals the importance of hidden capital in a nation’s wealth, making the difference where economic growth is concerned, as the most developed countries record the highest scores of efficiency in terms of intangible capital.knowledge economy indicators, hidden wealth, intangibles, GDP

Virtual monitors vs. physical monitors: an empirical comparison for productivity work

Virtual monitors can display information through a head-worn display when a physical monitor is unavailable or provides insufficient space. Low resolution and restricted field of view are common issues of these displays. Such issues reduce readability and peripheral vision, leading to increased head movement when we increase the display size. This work evaluates the performance and user experience of a virtual monitor setup that combines software designed to minimize graphical transformations and a high-resolution virtual reality head-worn display. Participants performed productivity work across three approaches: Workstation, which is often used at office locations and consists of three side-by-side physical monitors; Laptop, which is often used in mobile locations and consists of a single physical monitor expanded with multiple desktops; and Virtual, our prototype with three side-by-side virtual monitors. Results show that participants deemed Virtual faster, easier to use, and more intuitive than Laptop, evidencing the advantages of head and eye glances over full content switches. They also confirm the existence of a gap between Workstation and Virtual, as Workstation achieved the highest user experience. We conclude with design guidelines obtained from the lessons learned in this study

Synthetic Analysis about Single-Criterion and Multi-Criterion Financial Assets Portfolio

This paper as a synthetic analyzis based on the Markowitz and Sharpe models deals with the problem of portfolio trying to determine both the optimum proportion of titles and the influence of a considered macroeconomic factor over their level of efficiency and risk. The improvement of these models was made through the introduction of a new model, the APT model (Arbitrage Price Theory), as a development of the uni-factorial CAPM model, in other words, the above-mentioned model only constitutes a particular form of the APT model trying to establish a relationship between the individual efficiency of a title from the portfolio and several macroeconomic factors. Also, this model involves the identification of macroeconomic factors influencing the profitability of the titles and the determination of the influence of these factors individually, through the application of the APT model

A New Approach in Rentability and Capital Risk Management

The paper deals with an analytical manner with the financial analysis of the decisions of investments, concentrating on the analysis of the profitableness and the risk of financial titles as part of a portfolio on the Romanian market of capital. First part deals with problems of modern theories of portfolio as a follow up of establishing the complex relationship of risk in the previous chapter and establishes that the analysis of the risk of a portfolio can only be made in close connection to the prognosis of profitability. Although the studying of these phenomena has been realised scientifically ever since the beginning of the 20th century, there can be established as components of the modern theory of portfolio a series of models of analysis and estimating of the relationship central to the management of the portfolio, namely the correlation profitability � risk. Second part proposes of a model for the financial analysis of risk and profitability starting from the necessity of establishing an influence of cultural, investment, educational factors upon the transactions made on the market and upon the course of stock, proposing a new measure for the quantification of the evolution of the individual profitability and the profitability of the market under the form of potential profitability

Study about Markowitz Model Applicability on Romanian Stock Exchange Market

This paper deals with the application of the analysis on a portfolio made up of eight titles, through determination of the portfolio with absolute minimum variation and of the frontier of efficiency. Thus, using the Markowitz model, the dimensions of the portfolio with minimum absolute variation could be established but its profitability was smaller than the profitability offered by the BET rating. The best strategy to follow in this respect would have been to adopt a passive strategy and to take over the structure of the rating in the investment of portfolio for a good profitability but with a higher risk
