The Impact

In general, the present value (PV) concept is ambiguous. Therefore, behavioural factors may influence on the PV evaluation. The main aim of our paper is to propose some method of soft computing PV evaluated under the impact of behavioural factors. The starting point for our discussion is the notion of the Behavioural PV (BPV) defined as an imprecisely real-valued function of distinguished variables which can be evaluated using objective financial knowledge or subjective behavioural premises. In our paper, a BPV is supplemented with a forecast of the asset price closest to changes. Such BPV is called the oriented BPV (O-BPV). We propose to evaluate an O-BPV by oriented fuzzy numbers which are more useful for portfolio analysis than fuzzy numbers. This fact determines the significance of the research described in this article. O-BPV may be applied as input signal for systems supporting invest-making. We consider here six cases of O-BPV: overvalued asset with the prediction of a rise in its price, overvalued asset with the prediction of a fall in its price, undervalued asset with the prediction of a rise in its price, undervalued asset with the prediction of a fall in its price, fully valued asset with the prediction of a rise in its rice and fully valued asset with the prediction of a fall in its rice. All our considerations are illustrated by numerical examples. Presented examples show the way in which we transform superposition of objective market knowledge and subjective investment opinion into simple return rate.

Tree Seed

The Mayten tree (Maytenus boaria Mol.), a native plant of Chile that grows under environmentally limiting conditions, was historically harvested to extract an edible oil, and may represent an opportunity to expand current vegetable oil production. Seeds were collected from Mayten trees in north-central Chile, and seed oil was extracted by solvent extraction. The seed oil showed a reddish coloration, with quality parameters similar to those of other vegetable oils. The fatty acid composition revealed high levels of monounsaturated and polyunsaturated fatty acids. Oleic and linoleic acids, which are relevant to the human diet, were well represented in the extracted Mayten tree seed oil. The oil displayed an antioxidant capacity due to the high contents of antioxidant compounds (polyphenols and carotenoids) and may have potential health benefits for diseases associated with oxidative stress.

Social Optimality

Some resource economists and policy-makers believe that market mechanisms in general and timber pricing through auctions specifically are the only solutions for forest management in Canada. In this paper, simple economic concepts of market, economic efficiency, and social optimality are discussed, and the specific features of forest resources and sustainable forest management and their implications for optimal resource allocation through the market are highlighted. Economic theory behind competitive timber pricing in two geographical regions is presented to demonstrate that in a competitive setting, the prices of timber need not be the same in the two regions. Timber pricing mechanisms used by different countries are summarized, and auctions, their limitations, and some important outcomes of timber auctions by the United States Forest Service are discussed. Market performances of residual value and auction-based timber pricing are compared. On the basis of these discussions, it is inferred that sustainable forest management cannot be achieved either by the market or by government-controlled mechanisms only. An optimal-mix of the market and government-controlled mechanisms is the only answer to achieve sustainable forest management. Key words: auction, Canada, economic efficiency, market, residual value, social optimality, sustainable forest management, timber pricing
