Figure 1
The diagram shows a horizontal line segment that visually represents a range from 0 to 1. At the far left end of the segment, the label “Restaurant 1” is written, and at the far right end, “Restaurant 2” appears. The segment includes three distinct black points placed along the line: the first at position x subscript 1, the second at x asterisk, and the third at x subscript 2. These points divide the segment into three parts. Directly beneath the segment, the interval from 0 to x subscript 1 is marked with a blue brace and labeled “D subscript 1 of (p),” while the interval from x subscript 2 to 1 is similarly marked and labeled “D subscript 2 of (p).” Above the position x subscript 1, the expression is “U subscript 1 equals 0.” Above the position x asterisk, the expression is “U subscript 1 equals U subscript 2.” Above the position x subscript 2, the expression is “U subscript 2 equals 0.”Partial market coverage.
