The term principal-agent problem is due to Ross (1973) (per Stiglitz, 1989). Other early contributions to this literature include Mirrlees (1974, 1976) and Stiglitz 1974, 1975).

### What are some good books and articles about the principal-agent problem?

I found "Contract Theory" by Patrick Bolton and Mathias Dewatripont to be a very nice and thorough book. It, however, might be too advanced, although you can skip the formalism and just read the ...

### What are some good books and articles about the principal-agent problem?

In my PhD program everyone was using The Theory of Incentives: The Principal-Agent Model by Jean-Jacques Laffont and David Martimort. It offers a formal and relatively complete treatment without being ...

### General mathematical model of incomplete contracts?

Just a model that can be used to state how (in)complete a particular contract is, whatever the reason. I remember a debate at the end of the 90's on Incomplete Contracts: Where do We Stand? by Jean ...

### Signalling in a moral hazard contract with informed principals (that know their own type before contracting)

I'm not sure what exactly you're looking for, but here are some wild guesses: Bolton and Dewatripont (2005) Contract Theory, MIT Press. [Probably Chapters 5 and 6] Maskin and Tirole (1990) "The ...

### Is "avoiding being the bearer of bad news" an example of the "principal-agent problem"?

I think it is. Intelligent economist site states: The Principal Agent Problem occurs when one person (the agent) is allowed to make decisions on behalf of another person (the principal). In this ...

### Integrate a sufficient statistic

The fact that $$\frac{g_{a_i}(y,a)}{g(y,a)},$$ is the same for all $y$ for which $T_i(y) = T_i$ implies that the fraction can be written as a function of the value of $T_i(y)$ and $a$ alone. So ...

### Principal-Agent Problem with Two Agents

While it's not explicitly mentioned in the question, it seems safe to assume that the manager gets to observe separately the outcome of each worker, i.e. the value of $v_i$ for $i=1,2$. If this is the ...

### What is the implicaiton of agent risk neutrality in moral hazard?

It is true that when both principal and agent are risk neutral, the first best can be obtained despite asymmetric information. You should refer to a textbook, such as MWG (ch.14), for the technical ...

### Signalling in a moral hazard contract with informed principals (that know their own type before contracting)

Contracting with an informed principal is not so easy because the agent can learn about the principal's type from the kind of contract offered. This introduces signaling, which can quickly get messy. ...

### First order conditions in a Moral Hazard problem

Notice that MWG choose a wage function $w(\pi)$ to maximize profit, not a wage level $w$. As footnote 6 on p.481 of MWG says: The first-order condition for $w(\pi)$ is derived by taking the ...

### Question on uncertainity

We are given that $u$ is increasing and concave, and $u(0) = 0$. This implies that $\dfrac{u(t)}{t}$ is decreasing in $t$, and also, $\dfrac{u(t)}{t} > u'(t)$ for all $t$. Nicole's maximization ...

### locating specific model from organizational economics

This looks like a contest. There is a large economic literature on contests. Have a look at this survey by Corchón and Serena. Often these papers use a Tullock contest success function or model the ...

### Integrate a sufficient statistic

I add to the great answer of tdm some specifications about the term for almost all, because it is very important in mathematical analysis and in probability theory, and it is very likely to find it in ...

### What are some good books and articles about the principal-agent problem?

"The Economics of Contracts" by Bernard Salanié is nice and concise. Like the Bolton and Dewatripont book suggested by Bayesian (and most other books on this topic) it is pitched at a graduate level ...

### difference between screening game and moral hazard game

Moral hazard models feature agents' hidden actions (or these actions are not contractible). For example, a manager's contract cannot determine a wage contingent on the manager's effort, only ...

### Binding constraints at second-best optimum

I think its not a complex issue: a) You need to keep the high type agent from pretending to be the ow type agent, so you give him an extra compensation from showing his high type. But this nice deal ...

### Relation between incomplete contracting and the principal agent problem?

Not all principal-agent problems are the result of incomplete contracts, no. In fact, in most principal-agent problems, complete contracts are assumed. An incomplete contract is one that cannot be ...

### What is the implicaiton of agent risk neutrality in moral hazard?

From Bolton and Dewatripont Contract Theory (2005, p.135): "In the absence of risk aversion on the part of the agent and no wealth constraints, the first best can be achieved by letting the agent "...
