  1. Based on your understanding of market failures, give at least 3 different examples of situations that would give rise to market failures. In each instance make sure to discuss exactly why, and in what sense, each situation will give rise to a market failure.
  2. Give at least two examples of situations in which externality problems are not likely to be solved without government intervention. For each of these cases make sure that you discuss what you believe would be the best response to the externality problem at hand.
  3. Give at least two examples of situations in which externality problems are likely to be solved by private parties without government intervention as suggested by the Coase Theorem. For each of these situations make sure that you also discuss exactly how you believe that the private parties in question would be most likely to address the situation.
  4. The presentation on Public Goods and Common Resource Goods below includes the following table which suggests that we can classify goods into four different categories based on whether the consumption of these goods is rival and on whether non-payers can be excluded from enjoying the benefits of these goods. The table lists the following categories of goods: (1) Pure Private Goods, (2) Club goods (a.k.a. Non-Rival Private Goods), (3) Common Resource Goods, and (4) Pure Public Goods

Based on the logic of these classifications, identify at least two additional goods that you believe belong in each of these four categories and also explain why you believe that the additional goods that you have identified belong in the category in question.

  1. Give at least one additional example of market failure that arises from information failure in a market.
  2. Check out the examples below and follow the directions in the tutorials to conduct regression analysis for the following data set.

Describe, briefly (one paragraph) a situation in which and organization would use a test

Describe, briefly (one paragraph) a situation in which and organization would use a test

Test item reliability indicates how consistent the results produced from items on a test are. Consistency can refer to the items’ stability over time or the consistency of the items with each other. If an item is unreliable, statistical relationships will be weaker than they really are, and inappropriate conclusions may be drawn regarding the relationships between variables.

A measurement of reliability consists of the extent to which an observed score (which is the true score plus or minus error) accurately reflects the true score. Returning to the example in this week’s Introduction, if your true weight were 150 pounds and you stepped on the scale hundreds of times, it would sometimes show 149, sometimes 152, and sometimes 151. If you averaged all of those weights, you would come close to your true score. If you looked at how much the weights varied, you would have a good measure of the scale’s error. The situation is similar with a psychological test—a score on an IQ test represents an estimate of the theoretical “true” IQ; however, that observed score also includes error.

Researchers or test developers measure a test’s reliability with a reliability coefficient, generally a positive correlation coefficient that is somewhat less than 1.00. (A correlation of 1.00 would indicate perfect correlation, which is theoretically impossible due to inherent error in measurement.) Acceptable reliability coefficients for psychological tests or test items are generally at least .70. If you know a test’s reliability, you can calculate its margin of error, a “plus or minus” band that indicates an interval likely to contain the true score.

For this week’s Discussion, think of a specific testing scenario in an organization. Then consider a reliable test item for that testing scenario and an unreliable item for that same testing scenario. Consider how you might know if these items are reliable or unreliable.

With these thoughts in mind:

Post by Day 4

  1. Describe, briefly (one paragraph) a situation in which and organization would use a test (for example, selection, executive coaching, a training situation)
  2. Then, describe:

A reliable test item
An unreliable test item

  1. Have at least four (4) academic citations (see expectations announcement) drawing from the course readings.

NOTE – Part 2 of the discussion post is NOT easy. An understanding of what makes and item reliable is needed, in order to write a good and a bad item. The readings do not provide easy examples, but instead convey information that will, hopefully, help you understand such items.

An alternative source that might help you understand bad (unreliable) items is:

Survey Questions 101: Do You Make These 7 Mistakes?

But use what is gleaned from this (or other sites) to help understand the readings, not as a source cited in the discussion post.
