The growing social inequality and the abandonment of welfare-state model raise question return classes to historical arena. author argues that contemporary society can be characterized as capitalist due its main structural element - a pattern striving for profit; at same time, has changed vector making profit from external expansion (search new markets centers production) internal intensity (au...

Traditional backpropagation neural networks training criterion is based on goodness-of-fit which is also the most popular criterion forecasting. How ever, in the context of financial time series forecasting, we are not only concerned at how good the forecasts fit their target. In order to increase the forecastability in terms of profit earning, we propose a profit based adjusted weight factor f...

Based on data from firms in the personal computer industry, we study the effect of new product introductions on three key drivers of firm value: profit rate, profit-rate persistence, and firm size as reflected in asset growth. Consistent with our theoretical development, we find that new product introductions influence profit rate and size; however, we find no effect on profit-rate persistence....

The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization criterion in these algorithms is maximization of the total profit whilst satisfying...

This paper examines a firm’s investment intensity and timing decisions using a real options approach. The firm is endowed with a perpetual option to invest in a project at any time by incurring an irreversible investment cost at that instant. The amount of the irreversible investment cost determines the intensity of investment with decreasing returns to scale. The project generates a stream of ...

The appearance of fresh fruits and vegetables is a primary criterion in making purchasing decisions. Product appearance is characterized by size, shape, form, color, condition and absence of defects. A wide range of preharvest factors can modulate the appearance of the harvested product. These include: (1) biological factors (pathological, entomological, animal); (2) physiological factors (phys...

In order to cover their CO2 emissions, power companies receive most of the required EU ETS allowances for free. In line with economic theory, these companies pass on the costs of these allowances to the price of electricity. This paper analyses the implications of the EU ETS for the power sector, notably the impact of free allocation of CO2 emission allowances on the price of electricity and th...

stock selection criteria play a key role in contrarian portfolio construction. the usual approach is applying cumulative return as stock selection criteria however applying this criterion leads to ranking stocks without considering investment risk. in this study, we analyze contrarian strategies that are based on reward–risk stock selection criteria in contrast to ordinary contrarian strategies...
