An equilibrium in which agents with differing characteristics choose the same action. For example, in an insurance market a pooling equilibrium involves high-risk and low-risk agents choosing the same insurance contract.

What is separating equilibrium in insurance?
An equilibrium in which agents with different characteristics choose different actions. For example, in an insurance market high-risk agents and low-risk agents will choose different insurance contracts in a separating equilibrium.
How equilibrium is achieved in an insurance market?
Equilibrium in a competitive insurance market is a set of con- tracts such that, when customers choose contracts to maximize ex- pected utility, (i) no contract in the equilibrium set makes negative expected profits; and (ii) there is no contract outside the equilibrium set that, if offered, will make a nonnegative
Why might a competitive insurance market have no equilibrium?
When the distortion associated with self-selection is too large, there is always a pooling contract (purchased by high and low risk individuals) that will be preferred, in which case the “separating” equilibrium cannot be sustained. In this case, there exists no competitive equilibrium. insurance.
What is the difference between pooling and separating equilibrium?
A pooling equilibrium is an equilibrium in which all types of sender send the same message. A separating equilibrium is an equilibrium in which all types of sender send different messages.
What signals are chosen in a pooling equilibrium?
In a pooling equilibrium, senders of different types all choose the same signal. This means that the signal does not give any information to the receiver, so the receiver’s beliefs are not updated after seeing the signal. In a separating equilibrium, senders of different types always choose different signals.
What is the Rothschild Stiglitz model?
The Rothschild-Stiglitz model predicts that people who own life insurance should have fewer unobserved traits (that is, unobserved by insurance com- panies) that lead to a higher risk of death when compared against people with the same level of income but who do not own life insurance. FALSE.
What is asymmetry information?
What Is Asymmetric Information? Asymmetric information, also known as “information failure,” occurs when one party to an economic transaction possesses greater material knowledge than the other party. Almost all economic transactions involve information asymmetries.
What is adverse selection Econ?
Key Takeaways. Adverse selection is when sellers have information that buyers do not have, or vice versa, about some aspect of product quality. It is thus the tendency of those in dangerous jobs or high-risk lifestyles to purchase life or disability insurance where chances are greater they will collect on it.
