Selecting an Appropriate Market Demand Model
As the lead economist for a consulting firm, you are tasked with evaluating three proposed mathematical models for the market of a new product. Each model describes the relationship between the price (P) and the quantity demanded (Q), and is intended to be valid for Q > 0.
Model A: P = 1500 - 2Q Model B: P = 1000 + 3Q Model C: P = 1200 + 200/Q
Which model is fundamentally flawed because it is inconsistent with the general economic principle that an increase in the quantity of a good available for sale will lead to a decrease in the price consumers are willing to pay? Justify your choice by explaining the mathematical reason for its inconsistency and why the other two models are plausible representations.

Calculating an Individual's Consumer Surplus
Concavity of the Integrated Demand Function
Inverse Demand Function: Price as a Function of Quantity
A fundamental principle of market behavior states that the price consumers are willing to pay for a good decreases as the quantity available in the market increases. Given this principle, which of the following mathematical expressions, where P is price and Q is quantity (and Q > 0), could NOT represent a valid relationship between price and the quantity demanded?
Validating a Demand Function
Consider an inverse demand function given by P = 100 / (Q + 5), where P is the price and Q is the quantity demanded (Q > 0). This function is consistent with the economic principle that the price consumers are willing to pay for a good decreases as the quantity available increases.
Evaluating a Pricing Strategy
Match each mathematical function, which expresses price (P) in terms of quantity (Q > 0), to the description that best characterizes its adherence to the economic principle that the price consumers are willing to pay for a good decreases as the quantity available increases.
Constructing a Valid Demand Function
For an inverse demand function, expressed as P = f(Q), to be consistent with the general economic principle that an increase in quantity leads to a decrease in the price consumers are willing to pay, the derivative of the function, f'(Q), must be __________.
An economist is presented with a mathematical model for the price (P) consumers are willing to pay for a certain quantity (Q) of a product, expressed as P = f(Q). To determine if this model is consistent with the principle that price falls as quantity rises, they must follow a specific analytical procedure. Arrange the following steps into the correct logical order.
