Ian purchased an icewall refrigerator that regularly broke down. so, when his friend susan asked him to recommend a good refrigerator for her new home, ian said, "you can buy any refrigerator other than an icewall refrigerator because i had a bad experience with it." if susan forms a judgment based on what ian said, this bias of judgment is an example of the select one:
a. cognition-recall process
b. attribute recall heuristic
c. availability heuristic
d. judgment-encoding process
e. accessibility model

David consumes two things: gasoline (g) and bread (b). david's utility function is u(g, b) = 10g^0.25 b^0.75. use the lagrange technique to solve for david's optimal choices of gasoline and bread as a function of the price of gasoline, p_g, the price of bread, p_b, and his income m. with recent decrease in the price of gasoline (maybe due to external shock such as shale gas production) does david increase his consumption of gasoline? for david, how does partial differential g/partial differential p_g depend on his income m? that is, how does david's change in gasoline consumption due to an increase in the price of gasoline depend on his income level? to answer these questions, find the cross-partial derivative, |partial differential^2 g/partial differential m partial differential p_g.
