A company that provides home internet service cannot observe how its customers will use the connection after signing a contract. In contrast, a person selling their custom-built computer to a buyer online knows about a subtle, intermittent hardware flaw that the buyer cannot detect through the online listing. Which of these two scenarios contains a 'hidden attribute' problem?

An economist models a market with the following demand and supply functions, where P is the price and a, b, c, and d are positive parameters:

Demand: Qᴰ = a * P⁻ᵇ Supply: Qˢ = c + dP

Based on these functional forms, what can be concluded about the analytical properties of the market's equilibrium price (P*)?

Choosing an Appropriate Market Model

An economist is analyzing a market using the general functional forms Qᴰ = D(P, a) and Qˢ = S(P, c), where 'a' and 'c' are parameters that shift the curves. Even if the specific forms of the functions D() and S() are complex and non-linear, preventing the derivation of an explicit algebraic formula for the equilibrium price (P*), the economist can still correctly conclude that P* is a function of the parameters 'a' and 'c'.

Match each type of market model with its primary characteristic regarding the solvability of the equilibrium price (P*).

An economist is comparing two market models. Model A uses specific linear equations for supply and demand. Model B uses general, non-linear functional forms. Which statement accurately describes the key difference in what can be determined about the market equilibrium in these two models?

Contrasting Solvability in Market Models

An economist models the market for a specialized software product using the following non-linear demand and supply functions, where 'a' represents the impact of a recent marketing campaign and 'c' reflects the cost of server maintenance:

Demand: Qᴰ = a - ln(P) Supply: Qˢ = c + P²

Given these functional forms, which of the following expressions correctly represents the condition that implicitly defines the equilibrium price (P*)?
