Suppose there are two types of persons: high-ability and low-ability. a particular diploma costs a high-ability person $10,000 and costs a low-ability person $18,000. firms wish to use education as a screening device where they intend to pay $35,000 to workers without a diploma and $k to those with a diploma. in what range must k be to make this an effective screening device?

K must be in range $45000 ≤ k ≤ $53000 to make this an effective screening device.

Step-by-step explanation:

In order for the screening device to be effective, the range of k must be such that, it is more than the pay of a worker without diploma. The extra amount must at least be equal to the cost of diploma

So the value of k must be in range from (35000 + 10000) to (35000 + 18000)

Hence,

$45000 ≤ k ≤ $53000
