Evaluating a Simplified Housing Market Model
An economist develops a simplified model to predict changes in local housing prices. The model is built on the assumption that only two factors are significant: the average income of residents and the number of available houses. The model predicts that a 5% increase in average income will lead to a 10% increase in housing prices. However, after a year in which average incomes did rise by 5%, real-world data shows that housing prices only increased by 2%. Based on this information, evaluate the economist's model. In your response, explain the most likely reason for the significant difference between the predicted and actual outcomes, and discuss what this implies about the choices made when the model was created.

Evaluating a Simplified Housing Market Model
An economic model plots the quantity of a good on the horizontal axis and its price on the vertical axis. A curve is drawn on this model that is upward-sloping, but becomes progressively flatter as it moves from left to right. This curve connects all combinations of price and quantity that provide a firm with the same total profit. What does this curve represent?
Match each type of economic curve with its characteristic geometric properties, assuming standard models where goods are desirable and firms face diminishing returns.
In standard economic models, a curve representing a consumer's constant level of satisfaction for two desirable goods and a curve representing a firm's constant level of profit share the same geometric property of being convex.
Economic Rationale for Curve Shapes
Strategic Pricing Decision for a Differentiated Product
Consider two separate economic models. Model A illustrates the combinations of price and quantity that yield a constant level of profit for a firm producing a differentiated product. Model B illustrates the combinations of two different desirable goods that provide a constant level of satisfaction for a consumer. Which of the following correctly describes the typical shape of the curves in these models?
Comparing Economic Trade-off Curves
An economist is creating two separate graphs. Graph A is intended to show all combinations of price and quantity for a single product that result in the same level of total profit for a firm. Graph B is intended to show all combinations of two different desirable goods that provide a consumer with the same level of satisfaction. Which of the following descriptions correctly characterizes the typical shapes for the curves in Graph A and Graph B?
Evaluating an Analyst's Claim on Economic Curves
In standard economic models, a curve representing a consumer's constant level of satisfaction for two desirable goods and a curve representing a firm's constant level of profit share the same geometric property of being convex.
