Behavior of interest rates is of key importance for understanding the functioning of an open economy. The simplest models usually assume equal interest rates in individual countries, while the international arbitrage serves as a mechanism of their equalization. In our study an attempt has been made to determine whether and to what extend the interest rates in the Polish market are linked to the USA and the euro zone exchange rates. The analyses have been carried out for rates of different maturity terms, using the integration and co-integration concept.The analyses indicate that differences between the Polish interest rates, and those in the USA and the euro zone have strongly diminished. Cointegration analyses show the existence of a long-term linkages between the domestic and foreign interest rates, in particular with those in the euro zone. The nature of co-integrating relationships was different in the period 2001-2004 as compared with that after 2004, when we see a stronger impact of the euro zone rates than those of the USA. It may be assumed that the Polish accession to the EU had certain influence in the change of the above mentioned relationships.

The author carries out a cointegration analysis for the nominal exchange rate of the zloty against the euro according to a monetary theory developed by U.S. economist Jeffrey A. Frankel (1979). Wdowiński estimates a cointegration vector for the period 1999M7-2008M9. Long-term estimates show that the euro exchange rate depends on changes in industrial production and on short- and long-term interest rates, the author says. The influence of M1 money supply proves to be statistically insignificant. The departure of the euro rate from a state of monetary equilibrium was corrected slowly, the author says, because the half-life of the divergence was almost two years. The solution of the model showed that the euro exchange rate diverged significantly from a state of equilibrium determined by fundamental factors in the 1999M7-2004M1 period, while showing smaller deviations in the 2004M2-2008M9 period. Overall, the author observed periods when the zloty was both overvalued and undervalued against the euro due to a long-term equilibrium rate. The deviations stabilized noticeably from May 2003. In the 2003M5-2006M3 period, the zloty was overvalued by 9.6% on average, while in the 2006M4-2008M9 period it was undervalued by 9.3%. In the short term, the zloty tended to appreciate as a result of increases in short-term interest rates. According to the author, fundamental economic factors in Poland and the euro area point to the existence of a trend whereby the zloty is gaining ground against the euro, while short-term changes in this rate may be significant due to a growing macroeconomic risk.

Our objective has been to measure an impact of the two main global currencies - Euro and USD on shaping of exchange rates in countries of Central Europe. We have also endeavored to measure whether and to what extent a different approach to the Euro introduction as well as differentiated macroeconomic situation of these countries influenced the behavior of their exchange rates. The hitherto analyses indicate that the PLN rate of exchange was until 2004 strongly tied to the USD, but since 2004 links with the EUR exchange rate have become stronger. However the exchange rates of other countries in the region had been tied to the EUR earlier than the PLN exchange rate as they already had strong such links in the whole period of our analysis. Currency integration of the Central European countries is very strong although they are formally outside the euro zone and formation of their exchange rates should be perceived through trends of the EUR exchange rate versus other currencies, the USD.

Prices observed on emerging markets are affected by market sentiment changes. The article presents an interdependence analysis of a chosen set of sentiment indicators observed on the Polish OTC market. The set contains both interest rate market (basis swap, asset swap, convergence swap, overnight index swap), foreign exchange market (ATM volatility, risk reversal) and equity market (WIG20). The analysis is focused on cointegration and Granger causality approach in order to present forecasting power of elaborated models. Evidence from the market reveals economic link between the time series that comes from the strong influence of the cross-border trading between non-residents and local market makers. High responsiveness of daily prices of OTC instruments to the changes of the market sentiment and a level of the risk aversion can be proven. Moreover, error correction model using foreign exchange options has practical forecasting power generating adequate trading decisions taken by market makers

The paper investigates to what extent some basic tools of the ECBs monetary analysis can be useful for other central banks given their specific institutional, economic and financial environment. We take the case of the Bank of Russia in order to show how to adjust methods and techniques of monetary analysis for an economy that differs from the euro area as regards, for instance, the role of the exchange rate, the impact of dollarization and the functioning of sovereign wealth funds. A special focus of the analysis is the estimation of money demand functions for different monetary aggregates. The results suggest that there are stable relationships with respect to income and wealth and to a lesser extent to uncertainty variables and opportunity costs. Furthermore, the analysis also delivers preliminary results of the information content of money for inflation and for real economic development.

The aim of the study is to investigate the dynamic relationship between agro-food exports and production of agricultural sectors of EU countries in the period of 1994-2011. In the sake of accessing the degree of the interdependency between researched factors the time series techniques were employed. The first stage of the analysis was the assessment of the modeling process formal condition – the examination of variables stationarity. Because the stationarity hypothesis was rejected, the variables were differentiated to achieve stationarity. Subsequently, considered relationship was quantified by the mean of dynamic panel model. The model parameters suggest considerable impact of agro-food exports as immediate factor stimulating agricultural production among EU countries.

Celem opracowania jest analiza dynamicznej współzależności między eksportem produktów rolno-żywnościowych a produkcją sektorów rolnych krajów UE w latach 1994-2011. Do oszacowania charakteru współzależności między rozważanymi czynnikami wykorzystano techniki analizy szeregów czasowych. Pierwszym etapem badania była ocena formalnego warunku procesu modelowania – badanie stacjonarności zmiennych. Ponieważ hipoteza o stacjonarności została odrzucona, zmienne poddano różnicowaniu celem doprowadzenia do stacjonarności. Następnie z wykorzystaniem dynamicznego modelu panelowego dokonano kwantyfikacji zależności będącej przedmiotem zainteresowania. Parametry otrzymanego modelu sugerują występowanie wśród krajów UE znaczącego natychmiastowego efektu stymulacji produkcji rolnej przez eksport towarów rolno-żywnościowych.

Quantitative analysis is an appropriate tool to disentangle the impact of various recent shocks on price inflation in Poland. This article presents an econometric macro-model of prices and wages in which the direct impact of supply shocks transmitted from energy commodity markets on inflation is highlighted, and the impact of these shocks on the wage-price nexus. Due to the secrecy of data on the prices and volumes of natural gas imports from Russia to Poland, we propose a method for estimating the natural gas import deflator based on data on other main energy resources (crude oil and coal). The model allows us to assess to what extent domestic prices (CPI) depend on trends in world markets, including energy commodity prices. It is also possible to estimate the impact of fiscal policy on price developments. The equations of the model are constructed using cointegration methods for disaggregated consumer and import price indices. The properties of the system of 19 equations are investigated using multiplier analysis. We present the results of a simulation in which no anti-crisis measures were assumed during the COVID-19 pandemic. The obtained results indicate the important role of fiscal policy in shaping prices.

Różnorodność szoków oddziałujących na inflację cen w Polsce sprawia, że rozstrzygnięcie o roli każdego z nich nie jest możliwe bez wykorzystania właściwych metod analizy ilościowej. W artykule przedstawiono ekonometryczny makromodel cen i płac, w którym wyeksponowano bezpośrednie oddziaływanie na inflację szoków podażowych transmitowanych z rynków surowców energetycznych oraz oddziaływanie tych szoków na sprzężenie płacowo-cenowe. Ze względu na tajność danych o cenach i wolumenów importu gazu ziemnego z Rosji do Polski zaproponowano metodę oszacowania deflatora importu gazu ziemnego na podstawie danych o pozostałych głównych surowcach energetycznych (ropa naftowa i węgiel). Model umożliwia ocenę, w jakim stopniu ceny krajowe (CPI) zależą od tendencji na rynkach światowych (w tym od cen surowców energetycznych), a w jakim stopniu od cen krajowych; możliwe jest oszacowanie wpływu polityki fiskalnej na kształtowanie się cen. Równania modelu są konstruowane przy wykorzystaniu metod kointegracyjnych dla zdezagregowanych indeksów cen konsumenta i cen importu. Własności systemu 19 równań są badane przy wykorzystaniu analizy mnożnikowej. Zaprezentowano wyniki symulacji, w której założono niepodejmowanie działań antykryzysowych w okresie pandemii COVID-19. Uzyskane wyniki wskazują na istotną rolę polityki fiskalnej w kształtowaniu cen.

This sectoral study of the largest food exporters in the EU focuses on the impact of foreign trade in products made from agricultural commodities on the prospects of agricultural output development. In particular, the study analyses the interdependencies between the output and exports of selected goods. The methodology of vector autoregression was applied to describe the analysed relationships. The results of analyses support the hypothesis about the stimulating role of exports for output and, in the case of certain countries, identify the opposite direction of the causal relationship. The impact of exports on agricultural output is of a short-term nature. Exports appear to be more exogenous than output. The degree of exogeneity of agri-food exports is lowest in the Netherlands.

Badanie prowadzone w ujęciu sektorowym dla największych eksporterów żywności w UE koncentruje się na wpływie handlu zagranicznego produktami wytwarzanymi na bazie surowców rolnych na możliwości rozwoju produkcji rolniczej. Szczególnym przedmiotem zainteresowania są współzależności między produkcją a eksportem wskazanych towarów. Do opisu badanych związków zastosowano metodykę wektorowej autoregresji. Wyniki analiz wspierają hipotezę o stymulacyjnej roli eksportu w stosunku do produkcji, a w przypadku niektórych krajów identyfikują odwrotny kierunek relacji przyczynowej. Wpływ eksportu na produkcję rolniczą ma charakter krótkookresowy. Eksport jest czynnikiem bardziej egzogenicznym niż produkcja. Stopień egzogeniczności eksportu rolno-żywnościowego jest najniższy w Holandii.
