Purpose of this research is to shed light on the changes caused by shipping sulphur regulation, which will globally take off during years 2015 and 2020. It has significant effects on diesel markets globally, but especially in regions, where demanding 0.1 per cent level is required. One of these regions is the Baltic Sea. It is relatively undealt issue, how this forthcoming change will affect these specific sub-regions of stiff 0.1 per cent sulphur level demand and their transportation modes with different tax obligations.

The authors use second-hand data from various different sources, earlier research as well as simulation to estimate the effects on the diesel markets and transportation prices in the Baltic Sea region. Different transportation modes have diverging taxation treatment on diesel oil use, which complicates analysis further.

Based on research findings, it is rather probable that diesel markets for sulphur-free diesel oil shall face price spike in the beginning of 2015 in the Baltic Sea region. This is mostly explained with needed large-scale scrubber investment and short-time span to complete these (there are both technical and financial challenges). Therefore, numerous ships shall enter sulphur-free diesel oil market. Based on the simulation study, freight transportation will mostly be hurt in shipping, whereas road and rail shall face smaller price increases. Results are mostly explained with taxation treatment, where shipping is still using tax-free diesel oil, and no fixed taxes are hedging this transportation mode from sudden price changes.

Analysis concerns only Baltic Sea region, and effects and changes in the entire Europe from sulphur regulation change in 2015 are unknown. This would mean to extent study to North Sea. In addition, taxation system harmonization is not yet complete in Europe, and differences exist between member states. Research work was completed with diesel oil tax treatment regarding different transportation modes in Finland.

Based on this study, short sea shipping will be hurt by regulation change in 2015. However, in the future, this transportation mode shall face additional cost increases, as most probably, tax harmonization in diesel markets shall lead to fixed taxes added on shipping diesel. So, transportation mode shall face difficult and challenging times ahead.

Research is seminal study from possible sulphur regulation change implications in transportation mode level. It takes into account taxation treatment, cost share of diesel in transportation mode level and possible diesel price change. Until today, no other study exists in this detailed level.

Martin Winterkorn had high aspirations for Volkswagen to become the world's leading automaker when he was promoted to CEO in 2007. Volkswagen lacked the technology needed to meet American emissions standards and fulfill their promise of a “clean” fuel efficient diesel engine. Instead, they chose to deceive the world, violating the law and the foundation the company's code of conduct was grounded in. This case provides an opportunity to explore corporate governance, ethical leadership, and the ethical and professional responsibilities that senior executives have to create and maintain an ethical culture. Examination of the details in the case uncover value conflicts. Examples of values included in IMA's Statement of Ethical Professional Practice are honesty, fairness, objectivity, and responsibility. IMA describes these as “overarching ethical principles.”

This paper aims to analyze the economic viability of jatropha plantation in North East India.

Economic viability is measured through the net present value and the benefit–cost ratio (BCR) at four different production standards along with four different prices of jatropha seed.

At a very low price and small production, jatropha plantation is economically not feasible. However, when the price of seed increases from INR 5 to 8, BCRs become greater than 1, provided that the discount rate is less than equal to 8 per cent. The minimum threshold of BCR indicates that the threshold of 1.5 BCR at a production level of 1.5 tons/ha can be achieved with a combination of seed price of INR 10 per kg and a discount rate of 1 to 3 per cent. Thus, jatropha cultivation is economically viable but not highly profitable.

Present study analyzes the economic viability of jatropha plantation from purely financial point of view. Social cost and benefit of energy crop plantation is not included in the study. This suggests to adopt social cost–benefit analysis to evaluate the overall feasibility of plantation crops in future studies.

This paper contributes to the academic literature of economic viability of energy plantation crops. Economic viability of jatropha plantation is shown in different cost and revenue conditions with statistical evidences.

The aim of this study was to determine if there are asymmetries in the pass-through of West Texas Intermediate (WTI) crude oil prices to its derivatives (diesel and gasoline) in the Brazilian market.

Initially, the future WTI oil price series was analyzed using the self-exciting threshold autoregressive (SETAR) and logistic smooth transition autoregressive (LSTAR) non-linear models. Subsequently, the threshold autoregressive error-correction model (TAR-ECM) and Markov-switching model were used.

The findings indicated high prices throughout 2008 due to the subprime crisis. The findings indicated high prices throughout 2008 due to the subprime crisis. The results indicated that there is long-term pass-through of oil prices in both methods, suggesting an equilibrium adjustment in the prices of diesel and gasoline in the analyzed period. Regarding the short term, the variations in contemporary crude oil prices have positive effects on the variations in fuel prices. Lastly, this behavior can partly be explained by the internal price management structure adopted during almost all of the analyzed period.

This paper contributes to the literature at some points. The first contribution is the modeling of the oil price series through non-linear models, further enriching the literature on the recent behavior of this time series. The second is the simultaneous use of the TAR-ECM and Markov-switching model to capture possible short- and long-term asymmetries in the pass-through of prices, as few studies have applied these methods to the future price of oil. The third and main contribution is the investigation of whether there are asymmetries in the transfer of oil prices to the price of derivatives in Brazil. So far, no work has investigated this issue, which is very relevant to the country.

This paper examines the impact of Russian invasion of Ukraine on the intraday efficiency of four major energy markets, namely, diesel oil, Brent oil, light oil and natural gas.

This study applies the multifractal detrended fluctuation analysis (MFDFA) to high-frequency returns (30-min intervals) for the period from October 21, 2021, to May 20, 2022. The data sample of 5,141 observations is divided into two sub-samples, before and after the invasion of 24th February 2022. Additionally, the magnitude of long memory index is employed to investigate the presence of herding behavior around the invasion period.

Results confirm the presence of multifractality in energy markets and reveal significant changes of multifractal strength due to the invasion, indicating a decline of intraday efficiency for oil markets. Surprisingly, the natural gas market, being the least efficient before the invasion, turns out to be more efficient after the invasion. The findings also suggest that investors in these energy markets are likely to show herding, more prominently after the invasion.

The multifractal patterns, in particular the long memory property of energy markets, can help investors develop profitable investment strategies. Furthermore, the improved efficiency observed in the natural gas market, after the invasion, highlights its unique traits and underlying complexity.

This study is the first attempt to assess the impact of the Russia–Ukraine war on the efficiency of global commodity markets. This is quite important because the adverse effects of the war on financial markets may potentially cause destabilizing outcomes and negative effects on social welfare on a global scale.
