Bоnus questiоn (5 pоints) ref: OpenAI's Sorа, using the prompt — "Creаte two videos in which аn economics professor teaches the economics of AI, one with a smiling face and one without." First, generate a base image of the professor. Second, create a video without a smile. Then, generate the smiling version of the video using additional prompts. The entire process takes approximately 5–10 minutes. An economics professor wants to estimate the effect of smiling during online lectures on students' academic performance. To mitigate omitted variable bias and confounding factors, the professor employs a randomized controlled trial (RCT). Prior to implementing the RCT, the professor uses AI to generate counterfactual images and videos of themselves smiling. Students in the control group are randomly assigned to watch recorded lectures or view images of the professor without a smile. Students in the treatment group are randomly assigned to watch the same lectures or view images of the professor with a smile (generated using AI). The goal is to estimate the counterfactual treatment effect of the professor’s smile on students’ learning outcomes in an online setting based on the following linear regression equation:
