As businesses advance toward globalization, their supply chains have expanded. Globalization has brought together varied marketplaces, but it also has consequences. The most significant of these impacts is environmental damage. As organizations and customers are becoming growingly aware of the extent of the damage, organizations are transitioning towards greener practices. However, the long, complex supply chains make visibility and transparency in the chain, particularly beyond the first tier of suppliers difficult. Managing companies at a global scale become complex due to differences in interests and difficulty in managing information, material, and financial flow that require rigorous validation and management from external participants. This is where Blockchain Technology has immense potential. Blockchain is a new, ground-breaking technology with applications primarily in the financial sector. This thesis is exploratory by necessity, as it is an early work on blockchain's influence on green supply chain management. The study employs the funnel technique, which begins with a broad and general perspective before moving on to more particular aspects of the subject. A framework is designed based on a thorough assessment of the literature and real-world applications of blockchain technology. The findings show that incorporating blockchain into supply chain management can potentially increase understanding of the supply chain's hidden layers and aid in the transformation of the existing supply chain to a green supply chain.
Cryptocurrencies are becoming increasingly popular as an investment object due to the underlying promising blockchain technology, a growing number of use cases and especially because of their recent enormous price increases. As a young and emerging asset class, cryptocurrencies also face investors with several challenges and uncertainties.
This thesis investigates the impact of adding cryptocurrencies to diversified portfolios and whether cryptocurrencies can be a reasonable portfolio addition for investors. For this purpose, based on Harry Markowitz's Portfolio Selection Theory, a statistical analysis of portfolios with and without cryptocurrencies and different degrees of diversification was conducted for a 5-year-period. The portfolios were analysed in terms of return, risk and correlations and the efficient portfolio allocations as well as efficient frontiers were determined for different return and risk scenarios, both with and without the use of short sales.
The results of the statistical analysis showed that cryptocurrencies have significantly higher returns but also higher levels of volatility and risk than traditional asset classes. Although cryptocurrencies show less strong positive correlations with other traditional assets, they nevertheless correlate positively with the representatives of the traditional asset classes examined, which is why cryptocurrencies are only suitable to a limited extent as a means of risk diversification. Cryptocurrencies can be an attractive portfolio diversification but only for investors who are willing to accept higher risks for higher returns as the addition of cryptocurrencies significantly increases both the return potential and the risk of portfolios. Therefore, the higher an investor's expected portfolio returns and risk appetite, the higher should be the portion of cryptocurrencies in his portfolio.
