Publication Open Access Are crypto assets connected to real world shocks? the nexus between terrorist attacks, Bitcoin and NFTs*(Istanbul University Press, 2023) Özdurak, Caner; Sezgin, Firuze Simay; Graduate School of Social Sciences and HumanitiesThis study investigates the impact of terrorist attacks on the price fluctuations of Bitcoin prices and NFT sales. Although the value proposition of cryptocurrencies, Decentralized Finance, and the whole blockchain revolution is a quicker, cheaper, and more transparent kind of finance, various terrorist organizations tend to use cryptocurrency anonymously to finance their terrorist activities around the world by bypassing the banking system of the regulated countries. The analyses reveal that returns of Bitcoin and NFT markets are positively associated with the organization and funding phases of the terrorist attacks but negatively associated with the post-terrorist attack circumstances, meaning that it generates positive abnormal returns (AR) prior to the attack but creates negative AR right after the attack. Furthermore, while the Bitcoin news impact curve (NIC) is nearly symmetric, the NFT NIC is asymmetric, with positive shocks having significantly more impact on future volatility than negative shocks of the same magnitude. Since previous studies claim that terrorist attack news is good news for Bitcoin returns, we will enrich our AR analysis results with NICs results.Publication Metadata only The European Union's role in United Nations peacekeeping operations(Routledge Journals, Taylor and Francis Ltd, 2022) N/A; Sezgin, Firuze Simay; PhD Student; Graduate School of Social Sciences and Humanities; N/AThe European Union (EU) repeatedly expresses its support to principles and values of the United Nations (UN), seeing the UN as the core of a rules-based global order. How does the EU perform in contributing personnel to UN peacekeeping operations, and what factors affect their personnel commitments? Recent work shows that the size of the deployed personnel matters for peacekeeping effectiveness, and personnel commitment is a crucial effort by the UN member states to prolong peace. This article's contribution is to conduct the first analysis on the EU member states' contribution rates on 53 UN peacekeeping operations throughout the last 30 years. By testing arguments of two general explanations for factors that affect peacekeeper contributions, the empirical findings reveal that although the EU members tend to contribute less to UN peacekeeping operations, they contribute significantly higher in the case of rising peacekeeper fatalities. However, the EU member states are less likely to contribute with humanitarian impulse or international security threat concerns. The findings suggest that no single theory can explain the contribution motives; instead, a wide range of interacting factors determine the decision to commit personnel to an operation.
