| Abstract | The paper includes an analysis of changes in income sources of private agricultural farms. The work is based on numeric data from National Census of People from 1996 and 2002. The share of agricultural population financially dependent on agricultural production decreased. The share of agricultural population made a living by social incomes increased at the same time. |

| Abstract | Specialist bibliography offers an equation of the CML, but no formulae for market portfolio' s risk and return. It is connected with the omission of the equation of hyperbola, illustrating the interdependence between risk and return of a two-element portfolio. Co-ordinates of point C are the key for the selection of a portfolio with a predetermined risk of return from a ·CML. This paper fills in this gap. The paper also illustrates an issue of the short sale. Problems with the application of the above theory to multi-element portfolios consist in the fact that, starting from three-element portfolio, three is no clear equivalent of the equation determining the relation between return and risk. In a market portfolio the fundamental importance is attached to an adequate tangent to the hyperbola, its equation, and a point of tangency with the hyperbola. It means that it is impossible to apply the problem to the case of a portfolio assembled of a range of stocks (at least three) and one kind of bonds. Modifying the notion of a market portfolio by introducing a new notion of the so-called arbitrarily small risk portfolio, the author of this paper has achieved the possibility of a uniform characterization of portfolios assembled from any number of elements. A paper on the subject is prepared for publication. |
