In supply and demand analysis, when demand increases while supply remains constant, the typical market response is:
Correct Answer
C) Prices increase and absorption rates accelerate
Why this is correct: Basic supply and demand economics states that if demand increases (more buyers want properties) while supply stays fixed (same number of properties for sale), competition among buyers drives prices up. Additionally, with heightened demand, properties sell faster, meaning the absorption rate (the rate at which available properties are sold) accelerates. Why the other choices are wrong: "Prices decrease and absorption rates slow" describes a market with decreasing demand. "Prices decrease but absorption rates accelerate" is contradictory; price decreases typically occur with oversupply or weak demand, not accelerating absorption. "Prices remain stable but absorption rates slow" suggests no change in demand or an imbalance that doesn't affect price, which contradicts the demand increase. Exam tip: In supply/demand, price and absorption move together with demand changes: increased demand → higher prices + faster absorption; decreased demand → lower prices + slower absorption.
Why This Is the Correct Answer
Option B correctly identifies both market responses to increased demand with constant supply. Higher demand with unchanged supply creates competition among buyers, driving prices upward as buyers bid against each other. Simultaneously, the increased pool of buyers means properties will be absorbed (sold) more quickly from the market, accelerating absorption rates. This represents classic economic theory where scarcity relative to demand increases both price and velocity of sales.
Why the Other Options Are Wrong
DUPA Rule
DUPA: Demand Up, Prices Accelerate - When demand goes up with constant supply, both Prices and Absorption rates go UP together
How to use: When you see a supply/demand question, think DUPA - if demand increases, both price and absorption rate move in the same upward direction
Exam Tip
Always remember that price and absorption rates typically move in the same direction when demand changes - both up when demand increases, both down when demand decreases
Common Mistakes to Avoid
- -Confusing the relationship between price and absorption rate movements
- -Thinking that increased demand could somehow lead to lower prices
- -Forgetting that absorption rate measures how quickly properties sell, not how slowly
Concept Deep Dive
Analysis
This question tests fundamental supply and demand economics as applied to real estate markets. When demand increases while supply remains constant, there are more buyers competing for the same number of available properties, creating upward pressure on prices. The increased competition also means properties will sell faster, as multiple buyers may bid on the same property. This scenario represents a seller's market where property owners have pricing power due to scarcity relative to demand. Understanding this relationship is crucial for appraisers when analyzing market conditions and trends that affect property values.
Background Knowledge
Supply and demand theory is foundational to real estate economics, where price and absorption rates move in response to market forces. Appraisers must understand how shifts in buyer demand or property supply affect market conditions and ultimately property values.
Real-World Application
In practice, appraisers observe this when analyzing hot markets where low inventory meets high buyer demand, resulting in bidding wars (higher prices) and properties selling within days of listing (faster absorption)
