Economic effects of AI Introduction: The growing phenomenon of AI has many economic applications which will keep disrupting traditional business model and the economy the more developed it becomes. The links and public debates concerning digital platforms and the risks related to the use of data are proof of its potential and the growing place it has nowadays. We will focus on how AI allows companies to become more competitive and the ramifications that have come and might come because of such powerful tool. Therefore, the subject of our presentation will deal with how AI economic effects can be measured and the new economic theories that come with its development. The first part will be more business oriented with a benchmark to outline the different uses of AI whereas the second part will focus on economic theories and different approaches regarding this tool. I) AI is a tool with multiple practical uses a) Professional uses already implemented in different business areas Recommendation algorithm (Netflix, Spotify) Price positioning (Uber) Trends and visual modelling (using a picture to identify body size or visualize how clothes would look on you) fast fashion (Shein) Inventory and supply chain management (Amazon) Forecasting (Salesforce) b) R&D and possible future ramifications Possible new uses and upgrades: customization, predictive analysis, decision-making, automation, better chatbots (ChatGPT) etc. Uncertainties: researching and developing AI means betting on the future, externalities and side effects (job cuts, reshaping business models, new jobs and qualifications arising etc.), II) Economic effects on competition a) An asset leading to dominant position and winner-takes-all situation? Creating monopolies? New entry and exit barriers. Abuses of dominance b) Are regulations needed to make up for the unfairness of such tools? Data regulations Intellectual property and open source Compensating externalities Sources: Prediction Machines: The Simple Economics of Artificial Intelligence, Ajay Agrawal, Joshua Gans, Avi Goldfarb.
