Technology has deeply influenced the evolution of the auditing profession. New technologies such as Industry 4.0, blockchain, and apps, are expected to dramatically change the both current business model and society at large. The audit profession may need to adjust its existing paradigm in order to adapt to such a rapidly changing environment. Moreover, new audit approaches relying on advanced technologies could be used to improve assurance quality. This dissertation consists of three essays that explore the potential impact of emerging technologies on audit domain. The study contributes to the auditing literature by introducing Audit 4.0, blockchain, and apps to audit research, analyzing their potential applications in audit procedures, and proposing new paradigms that leverage those technologies to improve audit quality. The first essay foresees the impact of the fourth industrial revolution on the auditing profession, imagineers the use of new technologies promoted by Industry 4.0 for audit purposes, and identifies challenges in the transformation towards the new generation of auditing: "Audit 4.0". The second essay studies how blockchain technology could contribute to the accounting and auditing profession. Blockchain is the most disruptive information technology in recent years. Although the use of blockchain has been studied in many fields such as banking, financial markets, and government service, its application to accounting and assurance remains under-explored. This chapter discusses how blockchain could enable a real-time, reliable, and transparent accounting ecosystem, and how it could transform current auditing practices resulting in a more precise, timely, automatic assurance system. The third essay explores the use of apps to augment existing audit procedures. This essay first proposes a framework that provides guidance on app development and use. Based on this framework, this study designs a planning system that integrates apps into audit plans. Further, an intelligent app recommender system is designed to enable less experienced auditors to perform analytical audits. Finally, the planning system and the app recommender, together with other intelligent systems, are combined to create a new auditing paradigm: app-based auditing.
