• Abstract: Copyright policies play a pivotal role in protecting the intellectual property of creators and companies in creative industries. The advent of cost-reducing technologies, such as generative AI, in these industries calls for renewed attention to the role of these policies. This paper studies product positioning and competition in a market of creatively differentiated products and the competitive and welfare effects of copyright protection. A common feature of products with creative elements is that their key attributes (e.g., images and text) are unstructured and thus high-dimensional. We focus on a stylized design product, fonts, and use data from the world's largest online marketplace for fonts. We use neural network embeddings to quantify unstructured attributes and measure the visual similarity. We show that this measure closely aligns with actual human perception. Based on this measure, we empirically find that competitions occur locally in the visual characteristics space. We then develop a structural model for supply and demand that integrate the embeddings. Through counterfactual analyses, we find that local copyright protection can enhance consumer welfare when products are relocated, and the interplay between copyright and cost-reducing technologies is essential in determining an optimal policy for social welfare. We believe that the embedding analysis and empirical models introduced in this paper can be applicable to a range of industries where unstructured data captures essential features of products and markets.

  Generative AI is radically changing the creative arts, by fundamentally transforming the way we create and interact with cultural artefacts. This technology also raises ethical, societal, and legal concerns. Key among these are the potential displacement of human creativity, copyright infringement stemming from vast training datasets, and the lack of transparency, explainability, and fairness mechanisms.

  Generative artificial intelligence systems are trained to generate new pieces of text, images, videos, and other media. There is growing concern that such systems may infringe on the copyright interests of training data contributors. We propose a framework that compensates copyright owners proportionally to their contributions to the creation of AI-generated content.

• Generative AI and Copyright: A Dynamic Perspective [0.0]
  generative AI is poised to disrupt the creative industry. The compensation to creators whose content has been used to train generative AI models (the fair use standard) and the eligibility of AI-generated content for copyright protection (AI-copyrightability) are key issues. This paper aims to better understand the economic implications of these two regulatory issues and their interactions.
