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

Notes LECTURE Biochemistry 9.17.04 ATP is both a unit of energy currency in a cell and a building block of RNA. Why? It is believed that early in evolution there were very few molecules around. Many key pathways are ancient, and trace their origin to the early stages of evolution of life on Earth. Incidentally, such pathways are usually highly conserved in modern organisms. This is probably because once

Chapter 6 presents the supply side of the market using an approach parallel to that of the demand side of the market in Chapter 5. The chapter presents the material in a way that illustrates the second core principle of the textbook, that marginal benefits should equal marginal costs Chapter 5 presents the demand curve as derived from marginal benefit and Chapter 6 presents the supply curve as derived from marginal costs

Market power-the ability of a firm to profitably raise prices above marginal cost. Sources of market power: maintenance of market power requires barriers that prohibit or restrict entry of new firms

An individual has a comparative advantage in the production of a particular good if she can produce it at a lower opportunity cost than other individuals. An individual has an absolute advantage in the production of a good if she can produce more of that good than another individual. using comparable amounts of time. raw materials and effort
