Changes of financial system in the context of financial crisis
Karan, Boris ; Šíma, Ondřej (advisor) ; Pour, Jiří (referee)
In this paper, we analyse the relation between financial system and financial crises. Our goal is to find how, on the one hand, changes in the financial system affect the prospects for financial crises and, on the other hand, how the occurrence of financial crises shape the core elements of the financial system. We start by defining the financial crisis from three different perspectives. After it, we present the comprehensive history of financial crises that will allow us to continue by drawing some common patterns that are universal. Universal patterns in crises give us the ground for contemplating on some universal policy responses where we again follow different approaches. Taking into account the specifics of modern times and using the young and promising economy based on the blockchain, we are asking the question is this time different?. Analysis of initial development steps in the digital, trustless world gives us the basis for drawing parallels with the reality and the history. Our results suggest that there are many similarities throughout history and between the real and digital world. Instead of providing an exact answer on the question is this time different we conclude that there is a present strong feeling of Deja vu.

Ronald Coase by rád Bitcoin? Jak Blockchain snižuje náklady na transakci a mění koasijskou firmu
Kaid, Amira ; Stroukal, Dominik (advisor) ; Prokop, Jaromír (referee)
The rising popularity of blockchain technology otherwise known as the technology that underlies the Bitcoin protocol has been the subject of a lot of investigation and enthusiasm among financial organizations for its potentially revolutionary properties that will likely change how the economy works in the future. The blockchain is a decentralized open source ledger that records bitcoin transactions and is maintained by a distributed network of miners. Blockchain technology however has many applications beyond currency and can be applied in various areas including the firm organizational structure and law. This thesis examines how blockchain technology would lower the transaction costs involved in organizing the firm and how it would thus change the role of the firm. Coase (1937) in his article (The Nature of the Firm) explained that firms exist and continue to operate in a hierarchal manner because of the transaction costs that are involved in using the market mechanism. This paper also examines how the blockchain would lower the transaction costs of resolving disputes through carrying out market transactions that were mentioned by Coase (1960) in (The Problem of Social Cost). In order to achieve this aim Coases framework is used to theoretically model a future firm and legal system which are blockchain-based and that use bitcoin in their transactions. The results indicate that blockchain technology would reduce the transaction costs pointed out by Coase in such a way that it would cause the firm to become less hierarchal in nature and would allow it to adopt a more inclusive and distributed management system. Similarly in the case of law the transaction costs would fall making it easier for parties to resolve their disputes using the market mechanism instead of having to rely on a central authority.

Automatizace nákupu
Cizner, Pavel ; Vinš, Marek (advisor) ; Jirsák, Petr (referee)
The research goal was to find out the current and possible level of procurement automation and its contribution to less routine and more creative jobs. The goal was accomplished by literature review and data collection via survey. The data collected evaluated enterprises in developing and developed countries. The research hypothesis of developing countries automating more than developed ones was not supported by the data tested via Mann-Whithey U test. The data collected was from 146 respondents from all around the world. Therefore, there are limitations of the conclusions. The thesis and its survey contributes to the knowledge about the level of procurement automation.
