Leveraging machine learning in the global fight against money laundering and terrorism financing: An affordances perspective

Abstract

Financial services organisations facilitate the movement of money worldwide, and keep records of their clients’ identity and financial behaviour. As such, they have been enlisted by governments worldwide to assist with the detection and prevention of money laundering, which is a key tool in the fight to reduce crime and create sustainable economic development, corresponding to Goal 16 of the United Nations Sustainable Development Goals. In this paper, we investigate how the technical and contextual affordances of machine learning algorithms may enable these organisations to accomplish that task. We find that, due to the unavailability of high-quality, large training datasets regarding money laundering methods, there is limited scope for using supervised machine learning. Conversely, it is possible to use reinforced machine learning and, to an extent, unsupervised learning, although only to model unusual financial behaviour, not actual money laundering.

Public strategies to rescue the hospitality industry following the impact of COVID-19: A case study of the European Union

“…Stakeholder theory in tourism research was developed to better understand aspects of planning and development, and interactional and relational effects in inclusion and participation ( Bricker and Donohoe, 2015 , Canhoto and Wei, 2020 ). However, in a context of crisis like the current pandemic, the overall effects on the different stakeholders (which include businesses that cater for tourists, chambers of commerce, local government officials and landowners) should be managed in an efficient way by the regional governments ( Sonmez and Backman, 1992 , Birkland, 2006 , Wankmüller, 2020 ) through a strong coordination between all the institutions, efficient management of resources, a sense of political responsibility and educational initiatives ( Goniewicz et al, 2020 ).…”

“…• Unsupervised learning -Research efforts can be better utilised by focusing on unsupervised learning or reinforcement learning [13], considering the fact that AML data is highly imbalanced and true labelled data unavailability [108].…”
