A lot of regional studies cover classification of territorial units due to considering research problem. This approach examines territorial diversification of a phenomena, as well as spatial interactions. The occurrence of spatial dependence can reveal the processes of creating or extanding...

In this paper we present a new approach to integration and cointegration. We show that a periodically correlated time series can be divided in a natural way into subseries that are integrated. Moreover, with high probability they are cointegrated. Therefore it is enough to show periodic...

We examine the estimation problem for shape-restricted functions that are continuous, non-negative, monotone non-decreasing, and strictly concave. A sieve estimator based on bivariate Bernstein polynomials is proposed. This estimator is drawn from a sieve, a set of shape-restricted Bernstein...

The econometric literature offers various modeling approaches for analyzing micro data in combination with time series of aggregate data. This paper discusses the estimation of a VAR model that allows unobserved heterogeneity across observation unit, as well as unobserved time-specific...

DCF to metoda wyceny oparta na zalozeniu, ze wartosc przedsiebiorstwa zalezy od przeplywow gotowki, ktore firma moze wygenerowac w przyszlosci. Metoda ma jednak pewna wade zwiazana z faktem, ze do obliczania WACC stosowane sa ksiegowe wartosci dlugu i kapitalu wlasnego. Proby uzycia innych...
