The paper explores the competitive dynamics between human content creators and generative AI (GenAI) in the context of content creation. It introduces a competition model based on the Tullock contest, analyzing the tension and potential equilibrium between human and AI-generated content. The model considers two scenarios: exclusive competition where GenAI competes with human creators, and inclusive competition where human creators can choose to use GenAI. The study finds that despite the challenges posed by GenAI, a stable equilibrium can be achieved, characterized by a symbiotic relationship between human and AI creators. Key findings include: 1. **Modeling Content Creation Competition**: The model captures the interaction between human creators and GenAI, where the competitiveness of GenAI depends on the total body of human-generated content and its learning capability. 2. **Exclusive Competition**: The model shows that under mild assumptions, the game admits a unique pure Nash equilibrium (PNE), which is strictly monotone. This equilibrium is achievable through reasonable update rules in strategies. 3. **Inclusive Competition**: While the PNE of inclusive competition may not exist in general, the model demonstrates that in the 1-D competition case, a PNE exists with creators using GenAI only if they have the highest costs. 4. **Equilibrium Properties**: The paper provides insights into how the total body of content and social welfare are affected by market size, GenAI capability, and creator costs. It also explores how creators balance their efforts across different topics. 5. **Empirical Analysis**: Simulations validate the theoretical findings, showing that as GenAI's capabilities increase, the total utility and content creation by human creators decrease, while those by GenAI creators increase. However, a small group of highly skilled human creators may thrive due to reduced competition. Overall, the study suggests that while GenAI can disrupt the market, a stable equilibrium can be achieved through strategic use of AI by human creators, leading to a symbiotic relationship.The paper explores the competitive dynamics between human content creators and generative AI (GenAI) in the context of content creation.
