Y = -204 + . 34X1– .17X2
(17.0) (-1.71)
Where Y is quarterly sales of Activella, X1is the Novo’s advertising of the hormone
therapy, and X2is advertising of a similar product by Eli Lilly and Company,
Novo-Nordisk’s chief competitor. The parentheses contain t-values. Addition
information is: Durbin-Watson = 1.9 and R2= .89. Using the data for Novo-Nordisk,
which is correct?
a. Both X1and X2are statistically significant.
b. Neither X1nor X2are statistically significant.
c. X1is statistically significant but X2is not statistically significant.
d. X1is not statistically significant but X2is statistically significant.
e. The Durbin-Watson statistic shows significant problems with autocorrelation
Exhibit 15A-1
Suppose GM and Nucor Steel seek to develop jointly a new sheet metal and auto body
stamping machine, and each party knows the payoffs in the following table of
equi-probable outcomes but cannot independently verify one another’s costs. Both GM
and Nucor can cancel the project and both will then earn $0 if the cost revelations give
early warning of losses.
Note: The figures in parentheses represent costs associated with the Low and High cost
realizations, and all figures are in millions. The joint profit payoffs are the difference
between $180 and the sum of the cost realizations.
Part A: What is the incentive-compatible revelation mechanism that will induce true
revelation of the asymmetric cost information and maximize the value of the
partnership?
