The intersection of recent advancements in generative artificial intelligence and blockchain technology has propelled digital art into the spotlight. Digital art pricing recognizes that owners derive utility beyond the artwork's inherent value. We incorporate the consumption utility associated...

Robo-advisors provide investors with automated portfolio management services, and their growth is unprecedented. They performed less well during the COVID-19 pandemic than they had done during the non-crisis period. That less satisfactory performance was due to the fact that rare disasters are...

There are many public blockchains with various levels of success when it comes to sustained user adoption. This paper investigates whether some blockchains are more likely to dominate others in the long-run, i.e., whether there are "winner-takes-it-all" dynamics or whether a blockchain's...

We propose a tail dependence based network approach to study systemic risk in a network of systemically important financial institutions (SIFIs). We utilize a flexible factor copula-based method which allows us to measure the level of extreme risk in a portfolio when dependence is driven by one...

Cryptocurrencies come with benefits, such as anonymity of payments and positive network effects of user adoption, and transaction risks, such as unconfirmed transfers, hacks, and frauds. They compete with central-bank-regulated currencies as a means of payment but this competition is not...

We discover a novel flight-to-safety effect from cryptocurrency markets to stock markets. It occurs after a series of hacking attacks on crypto exchanges as greater uncertainty heightens investors' risk awareness and perception, which, in turn, induces herd-like behaviour in favor of safer stock...

Econometricians are increasingly working with high-dimensional networks and their dynamics. Econometricians, however, are often confronted with unforeseen changes in network dynamics. In this paper, we develop a method and the corresponding algorithm for monitoring changes in dynamic networks....

Cryptocurrencies come with benefits, such as anonymity of payments and positive network effects of user adoption, and transaction risks including unconfirmed transactions, hacks, and frauds. They compete with central-bank-regulated money but consumers may prefer one currency over the other. In...

We investigate the relationship between underlying blockchain mechanism of cryptocurren- cies and its distributional characteristics. In addition to price, we emphasise on using actual block size and block time as the operational features of cryptos. We use distributional charac- teristics such...
