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?

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*).

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*)?
