Analyzing and Explaining Deviations from the Law of One Price Online

A student is looking to purchase a new, factory-sealed copy of the video game 'Stellar Odyssey' for a specific gaming console. They use a price comparison website and find the following offers from five different reputable online retailers, with all prices including standard shipping: Retailer A: $59.99, Retailer B: $52.50, Retailer C: $59.95, Retailer D: $48.75, Retailer E: $55.00. Based only on this information, what is the most logical conclusion the student can draw about the online market for this specific product?

A consumer's preferences for goods X and Y are represented by the utility function U(X, Y) = 10√X + Y. Consider two consumption bundles: A = (25, 10) and B = (25, 30). How does the Marginal Rate of Substitution (MRS) at bundle A compare to the MRS at bundle B?

Designing an Online Price Investigation

Economic Sovereignty and Foreign Influence

You want to investigate whether a specific, brand-new, factory-sealed textbook ('Principles of Economics, 10th Edition, Hardcover') is sold at a single price across different online retailers. Arrange the following actions into the most logical sequence for conducting this investigation.

An economics student decides to test the idea that an identical good should sell for the same price everywhere. They choose a specific product: a new, 128GB, 'Midnight' color model of a popular smartphone. The student searches on a single major online marketplace and finds five listings from different third-party sellers with varying prices. The student concludes that the observation of different prices for the exact same phone model proves the economic principle is flawed. Which of the following statements identifies the most critical weakness in the student's conclusion?

The widespread availability of online price comparison tools ensures that identical, brand-new products will be sold at the same price by all online retailers, perfectly upholding the principle that an identical good should sell for the same price everywhere.

When investigating the online prices for a standardized product, an observer often finds that the price is not uniform across different sellers. Match each potential reason for this price variation with its correct description.
