Efficient Market Hypothesis And Behavioral Finance – Is A Compromise In Sight? By Nikolai Chuvakhin Legend has it that once upon the time two economists were walking together when one of them saw something that struck his mind. “Look‚” he exclaimed‚ “here’s a great research topic!” “Nonsense‚” the other one said‚ “If it were‚ someone would have written a paper on it by now.” For a long time this attitude governed the view of economists toward the stock market. Economists simply believed that

Practice with p-values Work through these problems with your computer partner and/or instructor. Answers follow the problem set. 1. Suppose we’ve done the computation of the Z test statistic. For each of the following situations determine the p-value that goes along with Z. a. Z = 2.12‚ two-sided test b. Z = 4.55‚ two-sided test c. Z = -1.40‚ lower-tail test 2. Suppose Z = 1.92.Which has a smaller p-value‚ the upper-tail test or the two-sided test? From this‚ is it more likely to have a

couple of decades there has been a debate going whether or not there are behavioral aspects in finance. This means that financial markets are subject to different investors’ sentiments and that markets are not efficient‚ i.e. the efficient market hypothesis (EMH) does not hold.

A new weight-watching company‚ Weight Reducers International‚ advertises that those who join will lose‚ on the average‚ 10 pounds the first two weeks with a standard deviation of 2.8 pounds. A random sample of 50 people who joined the new weight reduction program revealed the mean loss to be 9 pounds. At the .05 level of significance‚ can we conclude that those

Answer: H0: = 10 pounds H1: < 10 pounds Reject the null hypothesis if Z < -1.65 9.0 – 10.00 Z= ---------------- = -2.53 2.8/sqrt(50) The null hypothesis is rejected‚ the average weight loss is less than 10 pounds. p-value = .5000 - .4943 = .0057 32.

It is still being debated to on exactly when did the ancestor of our species began to walk on two legs. One hypothesis relies on a 6-7 million year old skull of Sahelanthropus tchadensis. The skull was discovered in the Djurab Desert in Chad. Since only the skull was discovered‚ it is still unclear on how Sahelanthropus tchadensis fits in our evolutionary
