When using the LM test for serial correlation, what is the null
hypothesis?
Select one:
a. No serial correlation is present.
b. It depends on the model specification.
c. Statistically significant serial correlation with the first

Use Statistical Tables to test for serial correlation given the
following Durbin-Watson d statistics for serial correlation. Draw a
picture for hypothesis testing. State your hypothesis.
i. d=0.62, K=2, N=21, 5-percent, one-sided positive test
ii. d=3.89, K=3 N=18, 5-percent, one-sided positive test
iii. d=1.31, K=4, N=36, 5-percent, one-sided positive test

What do we mean when we say that “people may lack self control”?
Is this argument consistent with the assumption of rational choice?
Governments around the world have adopted public policies to
control tobacco consumption, including information provision,
restricting smoking in public places, and imposing exercise taxes
on tobacco products. If people lack self-control, what is the most
effective policy for tobacco control?

Serial correlation, also known as
autocorrelation, describes the extent to which the result
in one period of a time series is related to the result in the next
period. A time series with high serial correlation is said to be
very predictable from one period to the next. If the serial
correlation is low (or near zero), the time series is considered to
be much less predictable. For more information about serial
correlation, see the book Ibbotson SBBI published by...

1. How is correlation measured?
2. What is the importance of correlation in investment
theory?
3. In Excel use a function = CORREL(highlight the first array
of data: Market Return, second array of data: Stock A
return).
Year Market Return,% Stock A return, %
2010 -6 -1
2011 1 0
2012 5 3
2013 -3 2
2014 0 5
2015 10 9
Find the correlation coefficient. Explain what that number
means regarding stock A and market rate of return.
