The AR(p) model
A) is defined as Yt = ?0 + ?pYt-p + ut. B) represents Yt as a linear function of p of its lagged values. C) can be represented as follows: Yt = ?0 + ?1Xt + ?pYt-p + ut. D) can be written as Yt = ?0 + ?1Yt-1 + ut-p.
The cost-minimizing rule is that a firm should utilize inputs such that the marginal physical product of an input divided by the price of the input is the same for all inputs. This is also the profit-maximizing rule because
A) we obtain the profit-maximizing rule by multiplying each ratio by the marginal revenue produced. B) we obtain the profit-maximizing rule by multiplying each ratio by the product price, which is the same for each input. C) the profit-maximizing rule is just the inverse of the cost-minimizing rule. D) they are exactly the same.
A person is dynamically consistent if:
A. lapses in his self-control never occur. B. his preferences over the alternatives available at some future date do not change as the date approaches or once it arrives. C. he always wants to follow through on his plans and intentions. D. All of these are necessary for dynamic consistency.
