In this paper an attempt was made to clarify the reasons of price movements on financial markets in the conditions of decision-makers bounded rationality. The emphasis of rationality of individuals, which is limited by information they have and the cognitive limitations of their minds, allowed to discuss the hypothesis of efficient markets and an assumption of their rational expectations. As a results of these considerations a model of financial markets was formulated in which an investor could choose different investment strategies and decide to change originally chosen ones as a consequence of their bounded rationality.

Celem artykułu jest dekompozycja zmian eksportu produktów rolno-spożywczych siedmiu nowych państw członkowskich Unii Europejskiej (tj. Bułgarii, Czech, Litwy, Polski, Rumunii, Słowacji i Węgier) w latach 2004-2014. Wykorzystano do tego metodę stałych udziałów w rynku (constant market share – CMS). Zgodnie z tą metodą na zmiany eksportu wpływają cztery czynniki: efekt wzrostu popytu światowego, efekt struktury towarowej, efekt struktury geograficznej oraz efekt konkurencyjności. Przeprowadzone badanie wykazało, iż do wzrostu eksportu rolno-spożywczego nowych państw członkowskich UE w analizowanym okresie przyczynił się przede wszystkim efekt wzrostu światowego popytu na żywność, a także w istotny sposób efekt konkurencyjności (z wyjątkiem Węgier).

The aim of the paper is to identify driving forces of the exports growth of agri-food products in the New EU Member States, namely Bulgaria, the Czech Republic, Hungary, Lithuania, Poland, Romania and Slovakia in years 2004-2014. To assess the factors of the exports development the constant market share (CMS) model was employed. According to the CMS approach, the exports growth depends on: the world demand effect, the commodity composition effect, the market distribution effect and the competitiveness effect. The obtained results show that the agri-food exports development of the New EU Member States in the period in question was mainly influenced by a favourable world demand effect. Except for Hungary, also the competitiveness effect contributed to the agri-food export growth.

The UK’s exit from the European Union resulted in significant implications for Poland and the entire EU. Brexit ended with an agreement on December 24, 2020 that set out the principles of future cooperation between the EU and the UK. This paper presents selected provisions of agreements regulating EU-UK relations from 2021 and assesses the effects of these provisions on the Polish economy. The analysis focuses on two issues: a/ changes in trading rules for goods and their implications for Polish trade, b/ financial provisions and their impact on Poland’s settlements with the EU budget. The main conclusion is that, despite the lack of customs duties, the cost of administrative services increased as a result of the introduction of transport documents and technical certificates. The deliveries of many products traded within international value chains were disrupted. Brexit also had a negative impact on Poland’s financial settlements with the EU budget. It eliminated the cost of financing the British rebate and associated rebates. But countries that earlier benefited from the reduced financing of the British rebate have won new correction mechanisms covered by other EU members.

Wystąpienie Wlk. Brytanii z Unii Europejskiej (UE) spowodowało znaczące implikacje dla Polski i dla całej UE. Brexit zakończył się wraz z uzgodnieniem 24.12.2020 r. umowy określającej zasady współpracy między UE i Wlk. Brytanią od początku 2021 r., tj. po zakończeniu okresu przejściowego. Celem artykułu jest wskazanie na wybrane postanowienia umów regulujących od początku 2021 r. relacje między Polską i całą UE a Wlk. Brytanią oraz próba oceny skutków tych postanowień dla polskiej gospodarki. Przedmiotem analizy są dwie kwestie: a) zmiana warunków prowadzenia handlu towarami i jej implikacje dla polskiego handlu oraz b) postanowienia finansowe i ich wpływ na rozliczenia Polski z budżetem unijnym. Główne wnioski są następujące: mimo braku ceł wzrosły koszty obsługi administracyjnej ruchu towarowego, m.in. w wyniku wprowadzenia dokumentów celnych, certyfikatów technicznych, sanitarnych itp. Zakłócone zostały dostawy wielu produktów, których handel odbywa się w ramach międzynarodowych łańcuchów wartości. Brexit wpłynął też negatywnie na rozliczenia finansowe Polski z budżetem UE. Z jednej strony wyeliminował on koszt finansowania rabatu brytyjskiego i pokrewnych rabatów. Z drugiej jednak państwa korzystające wcześniej z obniżonego finansowania rabatu brytyjskiego wywalczyły nowe mechanizmy korekcyjne, które są pokrywane – jak poprzednio – przez wszystkie pozostałe państwa, w tym Polskę.

In March 2007, the European Union and Ukraine opened negotiations on an association agreement to replace the existing agreement on partnership and cooperation. The main part of the new agreement will be a deal on the establishment of a free trade zone between the EU and Ukraine. The paper aims to examine the commercial implications of such a zone for Poland, especially as Ukraine is one of the largest export markets for Polish goods and Poland is the second largest commercial partner for Ukraine in the EU27 in terms of trade volume. The authors estimate the results of reducing import duties in terms of trade creation and diversion effects. They also examine the potential implications of lifting export duties by Ukraine and of using trade protection policies by both sides. Even though the estimated commercial effects are moderate, the authors say, they conclude that a free trade zone between the EU and Ukraine would benefit Poland’s trade. The zone would enhance Polish-Ukrainian relations without harming bilateral commerce, according to Ambroziak and Kaliszuk.

The article provides an overview of the changes in agri-food trade conducted by the EU member states in the years 2004–2015. The paper begins with a presentation of the EU regulations on trade with the third countries and trade within the Single European Market. Next, the paper focuses on the changes in agri-food trade of the EU (as a whole) with the third countries, paying a special attention to the impact of the Russian ban on food imports. The final section gives a detailed analysis on the changes to the Polish agri-food trade, both with the EU and non-EU countries. The authors show that during the analyzed period agri-food trade was growing dynamically not just in Poland but also in the EU, however higher growth rates were recorded in Poland.

The aim of this study is to assess the competitiveness of the Polish agri-food sector for 2004–2017, taking into account its most important sections. It begins with the discussion about the macroeconomic determinants of the competitiveness of the agri-food sector, i.e. the most important external (international) and internal (domestic) factors affecting its competitiveness. Next, the growth of foreign trade in Polish agri-food products is described, both in total volumes and the results in particular groups. The competitiveness of the Polish agri-food sector and its most important sections was assessed on the basis of two quantitative indicators: the trade coverage index (TC) and the revealed comparative advantage (RCA) in exports. The analysis shows that in 2004–2017 agri-food trade in Poland was growing dynamically and the indicators significantly improved in most sections. The authors claim that the improvement of the competitiveness of the agri-food sector in Poland benefited from favourable macroeconomic determinants, both international and domestic ones.
