Opis:
Valuation of forests and their components is a significant problem, both for science and practice. At present, in many countries, the market of forest property is limited. As a result, no conclusions may be inferred on the forest value based on the information on forest purchase and sale transactions. In this situation, we apply static methods of forest valuation. The problem of forest statics has been discussed for years (e.g., Brukas et al. 2001; Chang 1983, 2001; Dieter 2001; Hartman 1976; Manley and Bare 2001; Mohring 2001; Zhang 2001; Viitala 2016). Static methods of forest valuation are well known. In the construction of the proposed mathematical formula (Eq. 6), the Faustmann theory was applied, concerning the economic equilibrium in forestry. Numerous modifications of his equation for economic equilibrium were used to develop, for example, an income method for forest valuation based on discounting the final value or prolongation of initial value. The forest interest rate is a key element in these equations. At present, there are no procedures for the establishment of this interest rate, which would be generally accepted by the scientific community. Therefore, the article presents and discusses selected concepts for determining the forest interest rate.

Opis:
The article describes the accuracy of Altman and Mączyńska predictive models. The research material consisted only of financial economic reports from wood−furniture sector for years 2003−2012. Multiple discriminant analysis (MDA) was the main method applied in the study and which was used for three years in advance before bankruptcy. To evaluate the accuracy of the analysed models, the companies classification matrix and the odds ratio were used. Obtained results showed higher prediction accuracy of Mączyńska model. Moreover, comparing with the Altman model, Mączyńska system was better adapted as a multiple discriminant analysis model allowing forecasting of bankruptcy and continued functioning of companies in the wood sector.

Opis:
The article analyzes the possibility of using a seven−year development trend model to forecast the average price of wood sales (CGUS). Price models and forecasts were made on the basis of three different time series covering 7−year periods. The forecast of timber prices in individual years was developed on the basis of extrapolation going beyond the set of information adopted for research used to build the development trend model. We found that the size of the indicators of determination of the analyzed functions ranged from 0.5 to 0.6, and the convergence rates from 0.5 to 0.4. This means that the linear functions were characterized by poor adjustment to real prices. Despite this, the timber price forecasts differed from the empirical prices from PLN 1.81 to 13.91. In relative categories, the forecast error was in the range from 0.92 to 7.28%. Therefore, in our opinion, the research process presented can be a reference point as a comparative element to verify forecast results for other (non−linear) price forecasting models. The process of modeling timber raw material prices should be extended to other predictors related to the forest marketing chain. The predicted results from these models cannot be worse than those obtained by forecasting using linear functions

Opis:
The paper presents an analysis of price elasticity of large−sized timber on the primary local wood market. It was found that both price and volume of harvested assortments were changing. In the analysed period price elasticity of demand for individual assortments was periodically elastic and non−elastic.
