Abstract

The advancing degradation of the ecosystem and the occurring climate changes demand decisive action to be taken by citizens, aimed at levelling the results of the lack of balance between the natural environment and business operations. The growing importance of ecology is reflected on the international financial market in the form of green bonds. This article is devoted to green bonds which are a specific group of securities, namely ecological debt instruments. Despite the green debt being one of the most recent segments of the capital market, its very dynamic expansion can be observed year by year. The article is aimed at identifying the conditions for the development of the global environmental bonds market, specifically the factors stimulating and inhibiting the process. The article is a review in character and the following research methods were used in order to achieve the desired objective: analysis of subject literature and data analysis from the green bonds market, a case study, a descriptive and an inductive method.

Abstract

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.

Abstract

This paper presents research results of composite tubes filled with self-compacting concrete. The impact of the selected materials and geometric factors on resistance to the vertical shear was evaluated in this study. The resistance of the tested members was compared with recommendations given in Eurocode PN-EN 1994-1-1. From the results obtained in the tests it can be deduced that more parameters should be taken into consideration when determining resistance to the vertical shear in the interface between steel and concrete than PN-EN 1994-1-1 recommends.

Abstract

The recent financial crisis has seen huge swings in corporate bond spreads. It is analyzed what quality VAR-based forecasts would have had prior and during the crisis period. Given that forecasts of the mean of interest rates or financial market prices are subject to large uncertainty independent of the class of models used, major emphasis is put on the quality of measures of forecast uncertainty. The VAR considered is based on a model first suggested in the literature in 2005. In a rolling window analysis, both the model’s forecasts and joint prediction bands are calculated making use of recently proposed methods. Besides a traditional analysis of the forecast quality, the performance of the proposed prediction bands is assessed. It is shown that the actual coverage of joint prediction bands is superior to the coverage of naïve prediction bands constructed pointwise.

Abstract

Different methods are used for production of bronze bearings. In terms of technical specifications, the success of each of these methods depends on the bond’s strength and in terms of economic, the production method is important. In this study, the aim is to study the strength and microstructure of steel-bronze thrust bearing bond that has been produced through the casting using pre-mold. In this study, in order to bond, the raw metals are chemically washed with sulfuric acid solution for five minutes at first. Then, the molten bronze SAE660 is cast in a structural steel S235JR pre-mold. The bond’s strength has been measured using the shear test three times; the measurement of bond’s length has been done using field emission scanning electron microscope (FESEM). The results indicate that the strength of the bond is at least 94.8 MPa and bond’s length is 0.45 micrometers. Therefore, this method was successful for trust bearing application.

Abstract

In the article the author analyses the impact of the Financial Crisis, especially the Greek fiscal one, on the sCDS prices in Europe. The aim of the article is to assess the ability of the sCDS premia to price the risk of countries before and during the Greek crisis. The author analyses sCDS premia of maturity 10 years together with the so called bond-spreads, i.e. the spreadsbetween the countries’ bond indexes and the risk free rate of the region (in our case it was the yield of German bonds of corresponding maturity – 10 years).The idea was to check whether there occurred any discrepancies in the risk valuation via the two measures, as a consequence of the Greek crisis. The data is taken daily and covers the period of 2008‒2012. Based upon the results obtained in the research we conclude that the Greek crisis indeed influenced the relationships between the two measures of risk, however the degree of the influence was different in different countries. The relationships between the two measures of risk were totally broken only in the case of Greece, while in the other countries the relationships either were not distorted or had been broken already at the beginning of the financial crisis (2008/2009). The Greek problems were indeed reflected in volatilities of all analysed instruments; however triggering the credit event affected only Greek bonds dynamics.

Abstract

The goal of the paper is to verify the direction of sovereign risk transmission between sovereign CDS and sovereign bond markets in the Central European economies: the Czech Republic, Hungary and Poland. We focus on the hectic crisis period of 2008-2013. On the one hand, the sCDS market is said to react faster to the news than the sovereign bonds market. On the other hand, the bond market is related more closely to the internal situation of the country than the sCDS one and thus can price the sovereign risk more accurate. Moreover, the relationships between the markets can change during crisis time. We find that in the case of most risky and most indebted economy in Hungary there was a feedback between sCDS and sovereign bonds risk. In the case of Poland sCDS market risk Granger caused the risk of sovereign bonds – if we exclude instantaneous causality from the analysis; when it is included, feedback occurred. Eventually, in the case of the Czech Republic the risk of sCDS market Granger caused risk of the bonds market.
