Question 1
In this question, we will consider a model of incentives and disagreement where the principal can
either choose to give the agent an order, or persuade the worker. Unlike the model covered in class,
orders are binding.
There is a (P)rincipal and an (A)gent. A works on a project: he chooses effort e at cost -e and
a binary decision d (either -1 or 1). There is a binary state of the world 0 (either -1 or 1) that
is not known until after the agent makes his choices. The project is successful if and only if the
action matches the state (d = 0), in which case the principal receives revenue v = Be, where B > 0.
Otherwise, if the project fails, then the principal receives u = 0, and the principal also incurs an
additional cost of c = 1.
P can offer A an incentive scheme of the form r = bu.
So, the principal's and agent's payoffs are
7 = [v] - -
if the project fails
if the project succeeds
u = E - e2/2.
P and A disagree on how likely each state of the world is. P believes that 0 = 1 occurs with proba-
bility 1; A believes that 0 = 1 occurs with probability 1/3.
At the start of the game, P chooses one of two options.
. P can give A an order i (either -1 or 1). If A receives an order, he cannot disobey, and must choose
d = i; however, he can choose any effort level he likes.
. Or, P can persuade A. If P chooses to persuade, then she is successful 50% of the time: A changes
his mind, and believes (like P) that "0 = 1 will occur with probability 1". The other 50% of the time,
persuasion fails: A continues to believe that "0 = 1 will occur with probability 1/3".
The game proceeds as follows:
Step 1. The principal chooses whether to give the agent an order i, or to persuade the agent. If the
principal chooses to persuade the agent, then she learns whether persuasion was successful.
Step 2. The principal offers the agent an incentive contract r = bu.
Step 3. The agent chooses a decision d, and an effort level e 2 0. If the principal gave an order, the
agent must obey.
Step 4. The state of the world is revealed, and the project succeeds or fails (based on whether the
agent chose the correct action). The principal pays the agent his wage T....
a) Suppose the principal chooses to give 𝐴 an order. What order does 𝑃 choose? What effort level does the agent exert in step 3, given the principal's choice of incentive strength 𝑏 in step 2? What incentive strength 𝑏∗ does the principal optimally choose in step 2?
b) Suppose the principal chooses stopersuade𝐴 and that persuasion succeeds. What effort level does the agent exert in step 3, given the principal's choice of incentive strength 𝑏 in step 2? What incentive strength 𝑏∗ does the principal optimally choose in step 2?
c) Suppose the principal chooses to persuade 𝐴, and that persuasion fails. What effort level does the agent exert in step 3, given the principal's choice of incentive strength 𝑏 in step 2? Show that the principal will always receive the same payoff, regardless of the choice of incentive strength.
e) Explain, in words, why the principal prefers to persuade the agent (rather than order the agent) when 𝐵 is large.
