The principal-agent problem describes a class of interactions between two parties to a contract, an agent and a principal. The legal origin of these terms suggests that the principal engages the agent to act on his(the principal s behalf. In economic applications, the agent is not necessarily an employe

These notes introduce some ideas for modeling markets with adverse selec- tion. This framework was originally intended to deal with markets that cannot be easily accommodated by the standard signaling game e. g, be- cause there is two-sided adverse selection. For present purposes, however, it is enough to deal with the simplest case in which there is adverse selection

Proof Existence and uniqueness of r(t, u)and A(t)follow from Theorem 3. 1. Hence, in order to prove differentiability and the formula for the derivative, it is sufficient to show that there exist a function C: R++R+ such that C(r)/r-0 as r-0 and E>0 such

he variable t is usually referred to as the\time Note the use of an integral form in the formal definition(2.2): it assumes that the function tHa(a(t), t)is integrable on T, but does not require =a(t)to be differentiable at any particular point, which turns out to be convenient for working with discontinuous

5. Aromatic Compounds p: 153 Aromatic was used to described some fragrant compounds in early 19th century Not correct: later they are grouped by chemical behavior(unsaturated compounds that undergo substitution rather than addition Current: distinguished from aliphatic compounds by electronic configuration

Information content of a random variable Random variable x Outcome of a random experiment Discrete R V takes on values from a finite set of possible outcomes PMF: P(X=y)=Py) How much information is contained in the event X=y? Will the sun rise today Revealing the outcome of this experiment provides no information Will the Celtics win the NBa championship? Since this is unlikely, revealing yes provides more information than revealing Events that are less likely contain more information than likely events
