Abstrakt	Założenia, na których opierają się parametryczne metody estymacji dotyczące normalności rozkładu populacji oraz niezależności zmiennych, często nie są spełnione w przypadku danych finansowych. Dlatego istotną kwestią jest stosowanie metod estymacji odpornej (robust estimation) na te założenia, a tym samym na jakość obserwacji. Celem pracy jest implementacja metody odpornej do modelowania szeregu czasowego wartości indeksu giełdowego WIG20 o piętnastominutowej częstotliwości notowań w dniu 13.02.2006. Do szacowania parametrów strukturalnych modelu zastosowano estymatory odporne Welscha
Abstract	The assumptions which constitute the basis for parametric estimation techniques, relating to the normality of distribution of the population as well as independent variables, are often not fulfilled in the case of financial data. Therefore it is important to use robust estimation methods, both in terms of these assumptions and in terms of the quality of observations. The paper aims to implement the robust estimation to modelling the time series of the WIG20 index of the 15-minute frequency on 13 February 2006. The structural parameters of the model were estimated with the use of the Welsch estimators

Title	Bureaucracy and Country's Economic Growth
Słowa kluczowe
Key words
Abstrakt
Abstract	The objective of this paper is to show that the type of state bureaucracy is a key determinant of the country' s economic growth. In its theoretical part, the paper reviews the scientific literature that addresses the impact of the state organisation and quality of governance on economic growth and development: In the second part, the author empirically examines a quantitative relationship between macroeconomic performance in Poland over the 1995-2002 period and such bureaucracy characteristics as employment in public administration, defence and compulsory social security as well as the average remunerations in this section. The findings indicate that the country's economic growth rate and its GDP per capita are directly correlated to the level of employment and wages in public administration sector. According to simple linear regression analysis, both an increase in the number of public bureaucrats and the level of their wages adversely affect the rate of economic growth.

Title	Euro Zone versus new Member States of the European Union - Economic Divergence or Convergence?
Słowa kluczowe
Key words
Abstrakt
Abstract	Economic and Monetary Union is unique in that it combines centralised conduct of monetary policy by the European Central Bank (ECB) with national sovereignty over fiscal and other economic policies. Its main goals are providing greater macroeconomic stability and improving economic efficiency in the euro area. After implementation of the EU enlargement on l May 2004, the ten new EU member states now face the challenge of joining the Eurozone. Central and East European Countries (CEEC) differ significantly with regards to their economic performance. Of the eight countries in Central and Eastern Europe joined the EU, only Estonia and Lithuania currently meet all the Maastricht convergence criteria. EU membership gives the opportunity to catch up, but the actual economic outcomes depend on the quality of domestic policies.

Tytuł	Skala produkcji gospodarstw mlecznych a jej opłacalność
Title	The Scale and the Profitability of Milk Production
Słowa kluczowe
Key words
Abstrakt
Abstract	In years 1997-2001 in the typical family farms of the Central Macro region with the growth of production scale measured by: numbers of milk cows, milk production per year and commodity value of milk production with coupled production - the profitability of milk production and direct surplus from milk production grew. It is useful to intensify the milk production in those farms. State owned farms had from 42 to 173 milk cows. They achieved the highest direct surplus among the researched farms but average direct profitability fell to 2,41. In spite of taking into consideration the real indirect costs and the depreciation of farms' costs, the achieved profitability still gave the possibility of the growth of direct surplus. It means that a margin cost was higher than an average cost and simultaneously was smaller than purchase price, and that a margin surplus was higher than zero. The increasing of the direct surplus in these farms was possible but connected with a further decreasing of average profitability of milk production. Taking into the consideration the individual measure of the production scale and results received the direct profitability was the most negative correlated with the number of cows in the farm between 1997 and 1999: the index of determination was: 7,19%, 11,04% and 15,05%. Between 2000 and 2001 the direct profitability was the most negative correlated with amount of produced milk, which explained 13,47% and 11,36% changeability of the profitability of the production. The direct surplus in the analysed period was the most correlated with the value of commodity milk production and coupled production. Therefore when one wants to achieve high direct surplus from researched farms one should produce milk of the highest quality and also produce and sell with profit not only calves and defective cows but also farm heifers. In the analysed period the value of milk production and coupled production explained: 62, 30%; 66, 72%; 61, 97%; 90, 21 % and 86, 86% of direct surplus changeability.
