This paper uses a Markov-switching non-linear specification to analyse the effects of cyber attacks on returns in the case of four cryptocurrencies (Bitcoin, Ethernam, Litecoin and Stellar) over the period 8/8/2015-28/2/2019. The analysis considers both cyber attacks in general and those...

This paper examines mean and volatility spillovers between three major cryptocurrencies (Bitcoin, Litecoin and Ethereum) and the role played by cyber attacks. Specifically, trivariate GARCH-BEKK models are estimated which include suitably defined dummies corresponding to different types, targets...

We develop a novel firm-level measure of cybersecurity risk using textual analysis of cybersecurity-risk disclosures in corporate filings. The measure successfully identifies firms extensively discussing cybersecurity risk in their 10-K, displays intuitive relations with quantitative measures of...

We propose a taxonomy of cybercrime on the Ethereum blockchain and examine how cybercrime impacts victims’ risk-taking and returns. Our difference-in-differences analysis of a sample of victims and matched non-victims suggests that victims increase their long-term total risk-taking and earn...

Many modern organisations collect data on individuals’ personality traits as part of their human resource selection processes. We test experimentally whether revealing information on personality data impacts on pro-social behaviour as measured in a one-shot modified dictator game and a public...

The theory of expected utility maximization (EUM) proposed by Bernoulli explains risk aversion as a consequence of diminishing marginal utility of wealth. However, observed choices between risky lotteries are difficult to reconcile with EUM: for example, in the laboratory, subjects’ responses...

This paper studies the costs and benefits of delegating decisions to superiorly informed agents relative to the use of rigid, non discretionary contracts. Delegation grants some flexibility in the choice of the action by the agent, but also requires the use of an appropriate incentive contract...

Individuals use narratives as rationales or justifications to make their claims more convincing. I provide a general framework for partial verifiability based on narratives. Narratives give many reasons and arguments. The receiver derives the message’s meaning by aggregating these reasons; her...

Insurance for natural hazards - earthquakes, hurricanes, or pandemics - is rarely comprehensively adopted without intense government intervention, and even then it is often only a minority of properties or businesses that are insured. Efforts to close this insurance gap include the introduction...

Evidence suggests that participants in direct student-proposing deferred-acceptance mechanisms (DA) play dominated strategies. To explain the data, we introduce expectation-based loss aversion into a school-choice setting and characterize choice-acclimating personal equilibria in DA. We find...
