Bоnus questiоn (5 pоints) * ref: ChаtGPT4o Assume а counterfаctual framework. A student plans to start a new business developing AI-enabled smart glasses designed to assist drivers. The glasses provide real-time AI voice support, including navigation assistance, weather alerts, and warnings about potential driving hazards. The student seeks to evaluate the effect of using AI glasses on driving safety. Conducting controlled experiments with drivers is infeasible due to budget limitations and ethical concerns. Instead, the student assembles observational panel data from multiple U.S. states. Some states permit the use of AI glasses while driving, whereas others prohibit it. The dataset spans periods before and after the legalization of AI glasses in each state. The student compares changes in driving safety outcomes across states over time, implicitly constructing counterfactual outcomes for treated states using untreated states as a comparison group. To estimate the effect of AI glasses on driving safety, the student should use(1) ____________________ (a. causal inference or b. prediction). The experimental design described above is best characterized as a(2)____________________ (a. randomized controlled trial or b. quasi-experiment). After completing the analysis, the student finds evidence that the use of AI glasses improves driving safety in the observed sample. Building on this result, the student plans to enhance the product by adding a new AI feature that forecasts the real-time probability of a traffic accident. If the forecasted probability exceeds a predefined threshold, the glasses issue an immediate warning to the driver. This new feature is based on(3)____________________ (a. causal inference or b. prediction). Overall, because the study relies on real-world data and counterfactual reasoning rather than abstract theoretical modeling, this project is an example of a(4)____________________ (a. empirical or b. theoretical) study.
