4. THE OPPORTUNITY SET: CONSUMPTION, PRODUCTION, AND INVESTMENT CHOICE
the expenditure on wine does not exceed his income per time period. We can represent this income constraint (or budget constraint ) with the following expression: Equation (3)  P B Q B + P W Q W ≤ I <span>This expression simply constrains Warren to spend, in total, no more than his income. At this stage of our analysis, we are assuming a one-period model. In effect, then, Warren has no reason not to spend all of his income. The weak inequality becomes a strict equality, as shown in Equation 4, because there would be no reason for Warren to save any of his income if there is “no tomorrow.” Equation (4)  P B Q B + P W Q W = I From this equation, we see that if Warren were to spend all of his income only on bread, he could buy I/P B slices of bread.

    Suppose the question is “What is the probability that the stock earns a return above the risk-free rate (event A)?” The answer is an unconditional probability that can be viewed as the ratio of two quantities. The numerator is the sum of the probabilities of stock returns above the risk-free rate. Suppose that sum is 0.70. The denominator is 1, the sum of the probabilities of all possible returns. The answer to the question is P(A) = 0.70.

    Now suppose we want to know the probability that the stock earns a return above the risk-free rate (event A), given that the stock earns a positive return (event B). With the words “given that,” we are restricting returns to those larger than 0 percent—a new element in contrast to the question that brought forth an unconditional probability. The conditional probability is calculated as the ratio of two quantities. The numerator is the sum of the probabilities of stock returns above the risk-free rate; in this particular case, the numerator is the same as it was in the unconditional case, which we gave as 0.70. The denominator, however, changes from 1 to the sum of the probabilities for all outcomes (returns) above 0 percent. Suppose that number is 0.80, a larger number than 0.70 because returns between 0 and the risk-free rate have some positive probability of occurring. Then P(A | B) = 0.70/0.80 = 0.875. If we observe that the stock earns a positive return, the probability of a return above the risk-free rate is greater than the unconditional probability, which is the probability of the event given no other information.

    Question

    Blog
    [imagelink]

    Besides being slangy in appearance and sound, there is nothing remarkable about the word blog. It is short for Weblog and its etymon conveys what it is: a log (journal) on the Web that gives an account of a person's reflections and experiences. What might pique your interest is the histories of two relatively unfamiliar homographs of blog. They have absolutely no connection to the Internet blog—or to each other, for that matter—but the fact that blog was used many years prior to the Internet is surprising to many people.

    Blog is entered in the 1898 volume of The English Dialect Dictionary as a figurative use of block and is said to be "used of anything resembling a block or log of wood." The entry includes a quote from Joseph Thomas' 1895 Randigal Rhymes and a Glossary of Cornish Words: "I've a nice little blog of a horse." The dictionary also records an older verb use—"to look sullen or sulky"—illustrated by a 1746 citation: "Thee be olweys … blogging."

    Blog can also be found in Eric Partridge's A Dictionary of Slang and Unconventional English. It is defined as 19th-century schoolboy slang for "a servant-boy in one of the houses [on campus]" and is explained as a perversion of bloke. In the 20th century, this use of blog was extended to "a common boy of the town." There is also an entry for the verb blog used in 20th-century slang as a synonym of defeat.

    These forms of blog gradually faded away, but by the end of the 20th century a new homograph became prevalent in the English language, the Web blog.

    Enhanced discrimination (learning to differentiate the various types of problems) is not the only explanation for the interleaving advantage. During interleaved practice, switching among different problem types may strengthen the association between a problem type and its strategy, which promotes successful problem solving. With blocked practice, on the contrary, as all the problems require the same strategy, the student needs only focus on executing a given strategy repeatedly, which might not be as effective in reinforcing the association between a problem type and its strategy
