Opis:
Subject and purpose of work: This paper examines empirical implications of exchange rates in the economy of the Kingdom of Saudi Arabia (KSA). In particular, it aims to identify and evaluate potential macroeconomic signs and symptoms of economic disturbance so as to determine macroeconomic variables that influence spot exchange rate (1GBP = SAR), and to examine how fixed exchange rate regime influences exports and imports in the Kingdom of Saudi Arabia (KSA). Materials and methods: Multiple regression and simple linear regression models were used to analyze the data from 1975 to 2018. Results: The study found a weak and insignificant relationship between spot exchange rate and unemployment rate, inflation rate, exports, and economic growth, along with strong relations with imports, investment, and current account variation in the KSA. Conclusions: The study recommends the adoption of a floating exchange rate regime in the KSA. It has revealed the signs and symptoms of increases of the inflation rate with decreasing exports, increasing imports, decreasing of current account (current account deficit threat), and small increases of investment.
Przedmiot i cel pracy: W artykule przeprowadzono ocenę empiryczną implikacji zmian stopy wymiany walut w gospodarce Królestwa Arabii Saudyjskiej. Szczególnym celem artykułu jest identyfikacja i ocena potencjalnych sygnałów i symptomów makroekonomicznych zakłóceń w gospodarce i określenie makroekonomicznych zmiennych, które wpływają na stopę wymiany funta brytyjskiego na jednostkę waluty krajowej (1 GBP=SAR), a także dokonanie oceny w jakim stopniu system wymiany walut wpływa na rozmiary eksportu i importu Królestwa Arabii Saudyjskiej. Materiały i metody: W pracy zastosowano statystyczne modele regresji liniowej i metody regresji wielorakiej przy wykorzystaniu danych liczbowych za okres 1975-2018. Wyniki: W badaniach ujawniono słabe i mało znaczące powiązania między stopą wymiany waluty krajowej na waluty zagraniczne a stopą bezrobocia, stopą inflacji, wielkością eksportu, wzrostem ekonomicznym oraz silne relacje stopy wymiany walut na rozmiary importu, inwestycje oraz zmiany w bilansie obrotów bieżących Królestwa Arabii Saudyjskiej. Wnioski: Badania rekomendują stosowanie systemu zmiennej stopy wymiany walut w Królestwie Arabii Saudyjskiej. W wyniku badań zaewidencjonowano powiązane ze stopą wymiany walut sygnały i symptomy, takie jak: wzrost stopy inflacji, spadek eksportu, wzrost importu oraz powiększenie deficytu obrotów bieżących, a także spowolnienie procesów inwestycyjnych. Autorzy rekomendują wprowadzenie w Królestwie Arabii Saudyjskiej zmiennej stopy wymiany waluty krajowej wobec walut zagranicznych.

Opis:
Research background: Exchange-traded products (ETPs) are one of the most rapidly growing categories of financial products. Their fast development has been boosted by innovative features. Three main categories of ETPs are exchange-traded funds (ETFs), exchange-traded commodities (ETCs) and exchange-traded notes (ETNs). ETCs and ETNs remain least known, even though their number on some stock exchanges is high. In Europe, Germany is one of the largest and most active ETPs markets. ETCs and ETNs are debt instruments, in contrast with the most popular ETFs, which are equity securities. Therefore, they offer investors different advantages, but also expose them to other types of risks. Purpose of the article: The key aim of the article is to present the features of ETPs and to provide in-depth insight into the issues linked with the development of ETPs market in Germany, with the special emphasis on the ETCs and ETNs. Methods: In the main empirical part of the article, German ETPs market is analyzed using descriptive statistics and technological substitution framework (employed for the analysis of innovations in order to evaluate the changing market shares of, first, ETFs versus ETCs and ETNs, as well as, second, ETFs versus other types of investment funds). The period of the analysis is 2010?2016 in the former case and 2007?2016 in the latter. Findings & Value added: Share of ETPs other than ETFs in the total market in Germany remains low. Even though the market position of the leading products, i.e. ETFs, is still very strong, some substitution has been observed, especially after 2015. Predictions indicate that this trend will continue in the upcoming years. The results of the analysis of the investment funds? market confirm the substitution between ETFs and traditional investment funds over 2007?2017, in particular in the first years of this time period.

Opis:
The commodity exchange is regarded as one of the key institutions of market economy. Stockbrokers were a truly essential group of workers of the commodity exchanges. It was on the level of their organization and professional ethics that depended the level of efficient functioning of this institution. The basic law regulations, orders and stock charters were traced in this paper, which marked principles of stockbrokers’ activity. These principles were considered from the point of view of the ethical norms establishing the contemporary ethics of economic life. My special attention was concentrated on these principles of stockbrokers’ activities which concern the way of their appointing, rights as well as duties. „Ethical aspects” of stockbrokers’ activity on the Polish commodity exchanges were traced for the period from 1921 to the 1950. In initial period of the second Republic of Poland acted six commodities exchanges. In 1948 year stockbrokers institution was done away. The comparatively quick unification of exchange law by the government of independent Poland was the expression of understanding the importance which was fulfilled in economy by the institution of commodity exchange. In turn, issuing separate regulations for stockbrokers was proof of high position held by this group in the structure of the basic organs of a commodity exchange.

Information flows are often of greater importance than material and financial flows. As a result the competitive advantage of a company is largely determined by the internal and external communication system. Efficient and timely information exchange are of particular importance for the management of integrated supply chains. However, this information flow may be a barrier for trade partners at the same time. In the light of modern logistic conceptions such as CPFR, where a thorougly prepared system of data exchange between partners is essential, the current challenge is the opening up of companies for the informational needs of their partners.

stock exchange - urban experiment
Opis:
Over the past forty years, stock exchanges have undergone a number of transformations (legal, organizational and technological). They resulted both from general external conditions (including technological progress) as well as were the expression of various economic (structural) policies. Two of which seem to be basic. The first implemented in France, based on optimal centralization of stock exchange trading. The second one, implemented in Germany and Spain, expressing the concept of a complementary and effective combination of the potentials of the main trading floor and regional exchanges. Promisingly, especially in this latter dimension of experience together with the Edinburgh ‘stock market experiment’ that has just begun, they may reveal yet another not yet fully recognized characteristic of the stock market - the institutional exemplification of the market economy.

Opis:
Knowledge of the hydrodynamic conditions and the exchange of water in estuaries is important for ecological, navigational and water management reasons. The morpho-logy, river flow, sea level and local winds constitute important factors that influence the water currents and rate and extent of the mixing of salt and fresh water. The influence of the morphology changes on flow conditions, on the penetration of salt into the estuary and on the water exchange in the estuaries in this paper are analysed on the example of the Odra Estuary. The morphology of the Odra Estuary, and specially the Świna Strait, has changed immensely since the beginning of the XVIII century. The analyses were performed on the basis of data from in situ measure-ments and results of calculations. For the calculation the three-dimensional model ESTURO was used, because of the complexity of the hydrodynamic regimes and their three-dimensional character. The calculations were performed for the three different hydro-meteorological conditions for each of the five analysed morphological situations of the Odra Estuary. Some results of calculations have been presented.

The paper presents the possibility of applying spent synthetic ion exchangers and sorbents based on natural zeolites for the reclamation of degraded soils. The obtained research results confirmed the improvement of the soil sorption capacity (cation exchange capacity) caused by the addition of spent ion exchange sorbents. They also enabled to determine the magnitude of changes of the analyzed parameters depending on the amount of wastes introduced to the soil. The addition of 1% (w/w) spent cation exchanger enables to increase the cation exchange capacity twice, whereas in the case of zeolite, the observed increase reaches about 20%. Simultaneously, introduction of waste ion exchange sorbents increases the content of exchangeable calcium and magnesium while doubling in the content of these macroelements is observed for 5% (w/w) and 2% (w/w) of spent ion exchanger, respectively. In the case of the exchangeable potassium content, a satisfactory increase is observed with 1% (w/w) addition of spent zeolite.

Celem artykułu jest ocena skali zmienności kursu złotego w stosunku do euro i dolara, dokonana w porównaniu do kursów innych, wybranych walut krajów Unii Europejskiej: korony czeskiej, korony szwedzkiej, forinta węgierskiego i funta brytyjskiego. Do analizy zastosowano trzy wskaźniki: procentowe odchylenie kursu dziennego od średniej z badanego okresu i od średniej z poprzedzających dwóch lat oraz miernik ERV, a także przeprowadzono analizę korelacji. Zaobserwowano, że skala zmienności kursu złotego w stosunku do euro i dolara w porównaniu do innych walut nie jest zbyt znaczna oraz że stopień powiązania wartości walut z euro jest zasadniczo większy niż z dolarem, co przekłada się na wyższą stabilność ich kursów względem wspólnego pieniądza.
The aim of the paper is to evaluate the scale of volatility of the złoty’s exchange rate against the euro and the dollar, in comparison to the rates of other selected currencies of the European Union member states: Czech koruna, Swedish krona, Hungarian forint and British pound. Three indicators were used for the analysis: percentage deviation of the daily exchange rate from the mean in the studied period and from the mean in the preceding two years and the measure of the ERV, and also the correlation analysis was conducted. It was observed that the scale of volatility of the zloty’s rate against the euro and the dollar compared to other currencies is not very excessive and that the degree of linkage of the currencies’ values with the euro is substantially higher than with the dollar, which translates into greater stability of their exchange rates against the common currency.

Opis:
The object of the article are the questions concerning the „ethical aspects” of functioning of stock exchange law during partitions of Poland and in the first years of independent Poland. The analysis covers the period from 1817 (when in Warsaw the first official stock exchange on Polish territory was created) to 1921 when the first in independent Poland Act about the Organization of Stock Exchanges was passed. In the 19th century, several stock exchanges were created on Polish territory, from which the most essential were those in: Warsaw, Lvov and Lodz. The stock exchange was (and still is) regarded as one of the key institutions of market economy. Already, even on this account, the stock exchange law constituted the essential reference to economic law. On its basis the important institutions functioned, not only in the area of economy. In this article, the basic records of laws and exchange charters were traced, as well as different – essential for stock exchanges – documents (for instance, ministerial instructions), which set the principles of functioning of those institutions. The principles were considered from ethical norms’ point of view, which established ethics of economic life of that time. I have especially focused my attention on the principles of functioning of stock exchanges, which related to: the main stock organs, members of exchanges, as well as the so-called clientele. The stock exchange law also related to realities of that time, where-for different reasons – common cases of disobedience of the law occured. It should be stressed here, that stock exchange law was shaped on basis of economic legislation of the partitioners and that it was subject to changes along with political, economic and social transformations, which took place on Polish territory in the discussed period.

The aim of the article is to verify the impact of the ban on uncovered sCDS trade in Europe on the interdependencies between the sCDS market and other sectors of financial markets. We analyse two European markets: the safe and developed Swedish market, and the risky and developing Hungarian one. The study covers the period from October 2008 to October 2013. We analyse changes in the interdependencies between the sCDS market and the bond market, as well as between the sCDS market and the stock exchange. We found out that in the case of the safe Swedish market, the strength of relationships of each sector of financial markets with the sCDS one was much weaker than in the case of Hungary, which may suggest that the Swedish market is less prone to crisis transmission arising from herd behaviour or speculative attacks. In the end we show that in the two economies, the influence of the sCDS market on the other sectors of financial market indeed diminished following introduction of the ban on uncovered sCDS trade.

Opis:
This paper analyses the effects of fiscal policies upon agriculture and industry in Ukraine, with the SVAR model using quarterly data for the 2001–2016 period. The results indicate a positive effect of the government spending on both agricultural production and industrial output, while an increase in the government revenue is of the same expansionary impact for the latter only. Among other results, there is a weak negative short-lived spillover from agriculture to industry, with no causality running on the reverse. As agricultural production in Ukraine is associated with a higher level of government spending in the short run, a direction of causality seems to be just the opposite for industrial output. Both agriculture and industry bring about higher budget revenues in the short run, but for the latter this effect is lagged and more persistent. Controlling for fiscal policy effects, the nominal (real) exchange rate depreciation seems to be expansionary for industrial output. For agriculture, a nominal exchange rate depreciation is restrictionary in the short run, with an expansionary effect in the long run (however, this result is not supported in specification with the real exchange rate). Several implications of fiscal policy effects are discussed.

Opis:
Kurs walutowy jest jedną z ważniejszych cen w otwartej gospodarce. Z praktycznych i teoretycznych powodów bardzo użytecznym jest zbadanie jego poziomu równowagowego. Istnieje bardzo wiele teorii wyjaśniających kształtowanie się kursu walutowego. W artykule przedstawiono determinanty kursu walutowego, wynikające zarówno z teorii monetarystycznej, jak i teorii bilansu płatniczego. Następnie, na ich podstawie oraz przyjmując różne definicje równowagi, zbudowano predyktory nominalnego kursu PLN/USD oraz obliczono jego równowagowe poziomy. Przeprowadzona analiza empiryczna wykazała, że niezależnie od przyjętej definicji stanu równowagi otrzymane trajektorie poziomu kursów równowagi nie różnią się od siebie istotnie oraz są zbliżone do rzeczywistego kształtowania się kursu PLN/USD w okresie 1995-2003.
Exchange rate is one of the most important prices in an open economy. For theoretical and practical reasons it is useful to calculate an equilibrium level of exchange rate. There is a wide range of theories explaining exchange rate determinants. This article presents determinants of exchange rates derived from monetary theory and balance of payments theory. Upon these fundamental economic theories and defining different definitions of equilibrium we have calculated predictors of nominal exchange rate of PLN against USD. We have also computed equilibrium level of this exchange rate. Empirical results have shown that the theoretical equilibrium values do not statistically significantly differ on the method used in equilibrium computations and they are similar to the empirical trajectory of PLN/USD in the period 1995-2003.

Opis:
Surfactant and phenol were removed using AMBERLITE IRA 900 Cl ion-exchange resin, which is a strong alkali. In the process, the tests were carried out under non-flow conditions, the effect of contact time and ionite dose on the surfactant and phenol exchange was determined. The tests under the through-flow conditions were realized in three consecutive cycles, preceded by regeneration and rinsing. The obtained results served for determination of ion-exchange capabilities of the studied ionite. The usable ion-exchange capabilities of the resin obtained after the second and third ionite operation cycle were lower by about 10% (surfactant) and 14.29-17.86% (phenol) than those after the first cycle. It shows that the process of sorption occurred simultaneously with the ion-exchange process.
