William recently joined a VR chat world, where avatars (both NPC and user-controlled) roam the world and interact. This is William’s first time using VR, and he is surprised to find that he really does feel as though the avatars he is interacting with in the simulated world are real people. Which type of presence does this example reflect?

Bоnus questiоn (5 pоints) * ref: ChаtGPT4o An economist wаnts to estimаte the effect of recent tornadoes on small retail businesses in the Rolla area. To do so, the economist collects daily-level data for Rolla small business users, including text data from the Rolla subreddit, satellite image data, sales data, and insurance claim data. First, insurance data and tornado damage are highly correlated. Therefore, these independent variables may cause (1)_____________ in a linear regression model, leading to inflated standard errors and unreliable p-values. In this case, we can use (2)__________ to address the issue. Second, to extract meaningful information from unstructured Reddit text and satellite images, we must convert them into structured numerical data using (3)__________ . Third, after creating independent variables for tornado damage and other control variables, we plan to run linear regression. However, the number of independent variables is much larger than the number of observations. In this case, we can select a subset of predictors using (4)__________ . Finally, to measure the effect of tornadoes on small business sales in Rolla, we regress sales on tornado damage at the business level. We find that businesses experiencing internet and power outages suffer greater losses. To prioritize recovery support, we classify which businesses faced outages using generative AI. Since this classification creates dummy variables based on predictions, the resulting variables may contain errors. In this case, we must consider the risk of (5)__________ in the dummy variables, which may cause biased estimator. Overall, we can make optimal decisions to improve consumer surplus, business profits, and social welfare using our economics intuitions, econometric models, and computational methods with real-world data in the era of AI and big data.
