This dissertation studies blockchain technology in finance and accounting. In four essays, I examine Initial Coin Offerings (ICOs), accounting for crypto assets, and corporate use cases of blockchain technology. The first essay investigates whether and to what extent ICO investors consider the information provided in whitepapers when making investment decisions. The second essay examines the country-level determinants that encourage projects to raise funds through ICOs. The third essay analyzes how companies can account for crypto assets under IFRS. The fourth essay evaluates corporate use cases for blockchain technology in accounting and auditing.
