Differences in patients motivating factors influence their attitudes towards the role and quality of tourism agents’ services. This paper identified three major components (treatment-related, economic and travel-related) that explain patients motivation to travel for treatment. The study can help medical tourism agents to refine their marketing strategies and suggest the proper incentives to encourage participation in medical tourism. The research was made on the basis of a critical analysis of scientific literature, surveys and analyses.

The problem of governments’ over-indebtedness is one of the most important challenges for today’s EMU governance. As numbers suggest, the problem of extensive deficits has appeared in the EMU long before the burst of the global financial crisis. We suspect that the membership in a currency area might be partially blamed for such progression of indebtedness. This paper examines the determinants of government risk premiums in the EU Member States to answer if the risk premium assigned by the market may give currency area Member States additional incentives for profligacy. Controlling other factors, we investigate the pattern in which fiscal deficits and GDP growth affect the yield of 10-year-maturity government bonds in the euro area and the non-euro area EU Member States. Our results are straightforward. The market penalizes EU countries that do not belong to the euro area for bad economic performance and extensive deficits from 4 to 7 times stronger. Our estimates confirm the strong impact of the common credibility problem in the EMU but also support the key role of financial stress in determining the cost of government debt.

In this paper we present a copula-based model for a binary and a continuous variable in a time series setup. Within this modeling framework both marginals can be equipped with their own dynamics whereas the contemporaneous dependence between both processes can be flexibly captured via a copula function. We propose a method for testing the goodness-of-fit of such a time series model using probability integral transforms (PIT). This verification procedure allows not only a verification of the goodness-of-fit of the estimated marginal distribution for a continuous variable but also the conditional distribution of a continuous variable given the outcome of its binary counterpart (i.e. the adequacy of the copula choice). We test the model on an empirical example: investigating the relationship between trading volume and the indicators of arbitrarily ’large’ price movements on the interbank EUR/PLN spot market.

Over the past two years, coking coal prices have been the most volatile among major bulk commodities. On the supply side, the most important factor determining the movement of coal prices were weather problems affecting the exports of coal from Australia (Queensland), where the production of the best quality coking coals is concentrated. On the demand side, an important factor is the growing role of China on the market, which, being the world’s largest producer and consumer of metallurgical coal, has also become its largest importer. The dominant, about 75% share of China in the global spot market has resulted in their level of activity influencing the periodic price decreases or increases in international trade and prices based on CFR China (along with Australian FOB prices) have become important indicators to monitor market trends and determine levels of negotiated benchmarks. The exceptional volatility on the market led to a change in the quarterly price fixing mechanism for hard-load hard coal contractors in mid–2017 to apply a formula that assumes the valuation of their quarterly volumes based on the average of the basket of spot price indices. This reflects the broader trend of the evolving market, with growing spot market activity. The article describes the current situation on the international coking coal market and presents short-term forecasts for hard coking hard coal prices (PHCC LV), which are a reference point for fixing prices of other types of metallurgical coal (hard standard, semi-soft, PCI).

Over the past decade, the growing demand for imported coal from consumers (mainly Asian) coincided with supply constraints on the part of major suppliers. The sequence of events is referred to as force majeure. There were many events in the exporting countries, mainly including the cyclone and floods in Australia (Queensland, the world’s largest hard coking coal mining region). Imbalance between supply and demand causes commodity prices to be subject to cyclical changes, but in recent years the frequency and dynamics of these changes in the international metallurgical market (hard coking coal, semi-soft coking coal, PCI coal) has been extremely high. China, the world’s largest producer and consumer of coking coal, played a leading role in these events. Political action by the Chinese authorities regarding their domestic mining and metallurgical industries and the coke-chemical industry has made the country dethrone Japan since 2013 and has become a global leader in metallurgical coal imports. The rise of China’s importance in coal trading has become an important benchmark for monitoring market trends and benchmarking benchmarks. The market has become more bipolar and CFR China’s prices (in addition to Australia’s FOB prices). The paper describes the path of pricing mechanism changes in international trade contracts for metallurgical coal, against the background of market conditions that generate these changes.

Energy is a basic industry for any economy and ensures the country’s security, including economic

security. The purpose of the article is to analyze the reform of the energy sector in Ukraine

for successful integration into the energy sector of the European Union. The state of the energy

industry from 2003 to 2018 is analyzed. The following main reasons for the decrease in electricity

generation in Ukraine are identified – a decrease in production volumes, the annexation of Crimea

and the anti-terrorist operation in the east of Ukraine, a decrease in the volume of energy output

from Thermal Power Plants due to aging capacities, difficulties with raw materials, low efficiency,

which, however, has a good effect on the environment due to a decrease carbon dioxide emissions.

The directions of reforming the electric power industry of Ukraine are considered in the context of

“industry-market-company”. Four electricity market models are analyzed and the new model of the

competitor’s market for electricity in Ukraine with contract market, spot market, the balancing market

is substantiated. The structure of the segments of the new electricity market and the participants

are proposed. More than half of the electricity market is provided by nuclear power, which ranks

the 5th in the world in terms of installed capacity. The analysis of the performance indicators of the

nuclear company for 2007–2019 showed significant reserves for the company’s growth, which are

being successfully implemented through strategic development projects and phased corporatization

of the company as a tool of unbundling. The main challenges of implementation a new market

model are analyzed and solutions are proposed.

The paper presents a global perspective of the current technologies used for steel production and the steel markets. The iron and steel industry is a very complex sector that is strongly related with the rest of the economy due to the importance of steel products for industries such as construction, automotive, and other manufacturing sectors. Moreover, the iron and steel industry demands significant amounts of raw materials and energy, and most companies producing raw materials are located remote from the areas of highest steel demand. In consequence, both steel products and inputs are traded internationally (mostly by sea) and in large quantities, what additionally complicates analyses of the iron and steel industry. Steel prices depend on several variables, and there is not a single price for steel since there is a great variety of steel products traded. Those prices depend on supply and demand interaction (between steel producers and consumers, but also on interaction with other industries competing for the same inputs), and on transport conditions. As concerns the ownership structure, the steel industry consists of some large firms that operate globally and produce significant output, and many small firms that operate at a lesser scale. Recently, some of those firms have consolidated into large multinationals (such as ArcelorMittal, formed in 2006 by the merger of Arcelor and Mittal Steel, Arcelor being the result of the previous merger of Aceralia (ES), Usinor (FR), and Arbed (LX) in 2002). The results of this article form the basis for further long- and mid-term analyses of the development of the global steel industry. The main conclusion of the paper is that any future analysis of the iron and steel industry should be based on quantitative modelling tools that: (i) properly capture the technological diversity of the industry and the key features of the supply chain, (ii) are able to consider the strategic behaviour of all the key players of the industry, and (iii) consider all those factors at the global scale.

The paper investigates the supply structure of the capacity market in Poland in the coming years. The results of the capacity auctions conducted in 2018 are analyzed for this purpose. Three auctions were held at that time. The products traded in the capacity market are capacity obligations for the following years: 2021, 2022 and 2023. The auctions were organized in accordance with (i) he Act of December 8, 2017 on the Capacity Market and the (ii) Capacity Market Regulations published by the Polish Power Grid. The source of data used in this study is the official information of the President of the Energy Regulatory Office on the final results of the main auctions for 2021–2023 delivery periods. The list of the capacity suppliers who won capacity auctions contains the type of capacity market units, the volume of capacity obligations, the duration of capacity agreements and the business name of the capacity suppliers. The conducted analysis indicates that the auction for 2021 was won mainly by existing units (45.81%) and refurbishing units (33.51%). In subsequent years, the share of existing generating units is significantly higher and amounts to 91.67% for 2022 and 84.54% for 2023. The results of the study carried out in this paper also show that one energy company, being the owner of power generating daughter companies, has a very high share in these capacity auctions. The PGE Capital Group contracted 51.95% for 2021, 69.92% for 2022 and 64.44% for 2023 of the total capacity obligation. The volume amounts to over 70% of their total installed capacity.

The article presents a synthetic analysis of the crude oil market in Poland. As of today, this safety is provided mainly on the basis of native lignite and hard coal resources. However, the analysis of the hard coal market conducted by the authors indicates that the carried out mining restructuring (among others) led to an excessive reduction of mining volume and employment level in the hard coal mining sector. This led to a precedent situation when Poland became an importer of this energy carrier. In addition, the European Union’s requirements for greenhouse gas emissions must be taken into account. In connection with the above, it is necessary to search for new energy sources or technologies that enable hard coal to meet the requirements. It is possible to apply the so-called clean coal technologies that allow the greenhouse gas emissions generated during coal combustion to be reduced. As of today, they are not used on a mass scale, because the use of this type of technology involves additional financial expenses. However, taking into account that technologies have been growing faster and faster, are modernized in a shorter time, making a breakthrough discovery took hundreds of years, now it is often a few months, clean coal technologies can become the optimal solution in the near future. It is also necessary to diversify the sources of obtaining imported energy carriers.

The article describes coal and crude oil in terms of their mutual substitution. The article is a continuation of research conducted by the authors. Previous publications presented considerations on analogous topics related to natural gas and renewable energy sources. The crude oil market in Poland was analyzed and forecasts for oil extraction and the demand in the world and Poland by 2023 were presented. The SARIMA model was also created. The model made it possible to obtain oil an prices forecast.

About 55% of over 14 million Polish households live in multi-family buildings. Cooperative or housing association buildings have a large share in this group. The heat is supplied from the district heating network or from local sources. With respect to facilities fed from gas boiler rooms, the signing and execution of fuel supply contracts is required. From October 1, 2017, the obligation to submit tariffs for gas trading set for all final customers (except for individual gas consumers in households) for approval to the President of the Energy Regulatory Office was lifted. Decisions regarding the choice of the supplier and the content of the concluded contract are made by the authorized bodies of the cooperative or housing association. The consequences of such decisions are borne by the owners and users of residential premises. Ensuring the continuity of a contract for the supply of gaseous fuel essentially comes down to establishing prices and rates in force for a given period. The right decision on the moment of signing the contract or the amendment, termination of the existing contract and signing a new one, or negotiation efficiency will result in financial profits for all users. The costs of heating and domestic hot water preparation are a significant component of the overall cost of the maintenance of flats in Poland. Therefore, it is even more important that the prices and rates agreed upon with the gas supplier are as favorable as possible to users. The high costs of heat are not only expenses for apartment owners. The attractiveness of flat on the rental market is also decreasing. The business activity carried out in facilities located in such buildings is also less competitive.

The authors of the article analyzed gas prices on the Polish market over the last 3 years and presented the results of simulations of the effects of specific prices and rates set in the contract for the supply of fuel at the cost of heating from the point of view of a single apartment. As these are not large amounts per year, they do not motivate to optimize the terms of the gas purchase contract in this respect. The dynamics of changes in gas prices in Poland, although slightly different from world trends, is high. This makes it difficult for those responsible to make the decisions, and for residential users, it often means spending differences in subsequent years. One of the consequences of setting prices and rates significantly higher than obtainable may also be the reluctance of local communities to take measures to increase the energy efficiency of the heat supply system. From the point of view of heating costs, such decisions may distort the economic effect of thermo-modernization.

Modern cities are increasingly promoting their own individual brands to gain a competitive advantage. 28 Polish cities, after joining the Cittaslow international network of cities, can additionally use their native brand in their activities. The aim of the author was to answer the question: should cities only use an individual brand, or maybe they can support these activities with a common brand strategy. The growth of interest in individual brands of 28 cities belonging to the Cittaslow network has been evaluated, also their popularity, popularity of the native brand on the Facebook, and the use of the Cittaslow brand by cities on their websites were analysed. It was noticed that not all cities use the Cittaslow logo. But most cities in Cittaslow publish a link to the network and brand information on their websites. The native brand Cittaslow is in Poland at the positioning stage but probably its popularity will grow as the benefits from using it begin to be noticed.

The article discusses issues related to the generation, use, and transboundary movement of waste labeled with the code 191210 according to the waste catalogue regardless of its origin (municipal, industrial or mixed). Data contained in voivodship reports related to waste management and information about transboundary shipments shared by the Chief Inspectorate of Environmental Protection were also used in the article. The imbalance in the amount of produced and energetically used alternative fuels in Poland in the years 2015 to 2017 has been confirmed. This affects the economy of the waste management sector involved in the production of alternative fuels. The oversupply causes the prices of alternative fuels to fall and increases the need for subsidies in the case of the recovery or disposal of alternative fuels of lower quality. In the near future one should expect a stabilization of the supply of combustible waste to the cement industry, which is now beginning to achieve its technological potential; this is due to a high degree of replacement of fossil fuels. One should also expect an increase in the demand for alternative fuels from the commercial power sector and heating sector. It has been shown that much more alternative fuel is imported than exported from Poland. The amount of imported alternative fuel in the market is relatively low compared to the amount of fuel produced in the country. This oversupply affects, although not significantly, the possibility of using domestic waste for energy recovery. The export of the alternative fuel produced in the country is a favorable phenomenon when there is no possibility of sale on the domestic market. It seems rational, especially in the case of exports from installations producing fuels in border provinces.

The article presents an analysis of Russia’s participation in international steam coal trade, which has been its important participant for years. The research covered the years 2014–2018. The geographical location on two continents and the availability of coal deposits, favors its presence on both the Pacific and Atlantic markets. The article also discusses the main coal producers in Russia and the prices of Russian steam coal directed to the spot market. Due to the significant share of coal exports for the Russian economy, the focus was also on analyzing Russian seaports.

In recent years, Asian exports have dominated in Russian steam coal exports. The share of export to this market in the years 2014–2018 was in the range of 49–57% (60–87 million tons). Currently, three countries play an important role among Asian countries: South Korea, China and J apan. They purchased a total of 38–52 million tons of Russian coal. Although in the years under analysis Russia exported 52–67 million tons of steam coal to the European market, the share of this market dropped from almost half to around 40%. T he slow departure from coal energy contributes to reducing the share of recipients from this direction. Among European countries, in 2014 the main direction of export was Great Britain with 19% (24 million tons) of total export share. In 2018, exports fell to 9 million tons (5%).

Among European destinations for Russian coal, Poland’s share is growing in importance. In the years 2014–2018, steam coal exports to Poland varied in the range of 5.6–16.2 million tons. In the years 2014–2018 it changed in the range of 5.6–16.2 million tons. The dynamic growth achieved in the last three years is noteworthy. In relation to 2016, imports increased by 10.0 million tons and in 2018 amounted to as much as 16.1 million tons. The article also discusses the geographical structure of coal imports to Poland by railway border crossings and seaports.

The aim of the paper was to estimate how the value of 1 GJ of energy in coal with a calorific value of 5500 kcal/kg varies on the international coal market compared to 1 GJ of energy in coal with a calorific value of 6000 kcal/kg. The analysis of data from different ports was intended to answer the question of whether the pricing of coals of different producers according to their calorific value is convergent. The best-known price standard for thermal coal is 25.1 MJ/kg coal (6000 kcal/kg) and, until recently, coals with such quality parameters dominated international trade. Currently, coals with parameters other than considered to be standard parameters are traded on the coal market, hence it is necessary to price a unit of energy (e.g. 1 GJ) contained in these coals. The indices have been selected of the largest exporters of thermal coal for which data was available and referred to the same coal types (grades) determined on the same basis (FOB). Theoretically, the price differential between 6000 kcal/kg and 5000 kcal/kg coal (in USD/ton) should be (at least) as much as the difference in calorific value, i.e. about 9% per USD/ton. In reality, the price differential between these types of coal is greater, though. The overall conclusion of the analysis is that the price calculated per 1 GJ of energy fluctuated on average by 5.9% over the entire period considered. The analytical results obtained for coal from four countries are quite convergent, so it can be assumed that the calculated relationship between the prices of coal with different calorific values (6000 and 5000 kcal/kg) is a good approximation of the observed relationships in the international trade. The calculation results provide a simple formula allowing to estimate the price of coal with a calorific value other than the standard 25.1 MJ/kg (6000 kcal/kg) using the relationships from the international market.

The article contains considerations on the historical evolution of globalization in the context of the rivalry between two basic concepts of economic system: pro-state option and pro-market option. The author assumes that globalization is a permanent feature of human aspirations. In the beginning of modern era it was interlocked with the alternating dominance of pro-market and pro-state tendencies, and it continues to appear in the same form until present times. The liberal economic thought has expressed these opposition in the state versus market formula. Over the last five centuries there have been five stages of alternating dominance of pro-market and pro-state forces, connected with globalization. First was the mercantilism with the significant role of state, and its antithesis was the XIX-century free-competition capitalism. Two last stages – the neo-liberalism dating from 1980 to 2008 and its antithesis from 2009 to 2019 – have been presented in detail. The previous stages are shown only as historical background. The analysis is preceded by the outline of a theoretical model of globalization connected with the alternating dominance of pro-state and pro-market tendencies, which can be seen as value added to the legacy of economic thought devoted to the relationship between market and state.

Poland’s economy is closely connected with European markets, particularly within the European Union: almost 90% of Polish commodity export goes to European countries and 80% is absorbed by other EU countries. The common European market is absorptive, safe and stabile, and goods and services sold there are duty free. But the high concentration of exports in this market implies a strong dependence on the modest growth dynamics and local fluctuations of demand, while reducing the gains that could be obtained from the presence in emerging markets which include several large and rapidly growing developing economies. The paper gives a general characteristics of those markets, including the information on their economic and population potential, and their place in the world economy – at present and in the future (according to current statistical data and long-run forecasts). The statistics of Polish foreign trade indicates a very small share of emerging countries in the geographical structure of Poland’s exports. The author describes the chances and threats combined with export expansion to these markets, emphasizing that the net balance of benefits and risks is clearly positive, which should encourage Polish enterprises to take a more active part in trade and cooperation with those countries and regions.
