Systemic acquired critique of credit card deception exposure through machine learning

Dantas, Rui Miguel; Firdaus, Raheela; Jaleel, Farrokh; … - In: Journal of open innovation : technology, market, and … 8 (2022) 4, pp. 1-20

A wide range of recent studies are focusing on current issues of financial fraud, especially concerning cybercrimes. The reason behind this is even with improved security, a great amount of money loss occurs every year due to credit card fraud. In recent days, ATM fraud has decreased, while...

Crowding out the truth? : a simple model of misinformation, polarization, and meaningful social interactions

Germano, Fabrizio; Gómez, Vicenç; Sobbrio, Francesco - 2022 - This version: November 2022

This paper provides a simple theoretical framework to evaluate the effect of key parameters of ranking algorithms, namely popularity and personalization parameters, on measures of platform engagement, misinformation and polarization. The results show that an increase in the weight assigned to...

Human-algorithm interaction : algorithmic pricing in hybrid laboratory markets

Normann, Hans-Theo; Sternberg, Martin - 2022

This paper investigates pricing in laboratory markets when human players interact with an algorithm. We compare the … degree of competition when exclusively humans interact to the case of one firm delegating its decisions to an algorithm, an n …-player generalization of tit-for-tat. We further vary whether participants know about the presence of the algorithm. When one of three firms …
