Fill in the blanks to complete the passage about the law of one price. drag word(s) below to fill in the blank(s) in the passage. must according to the law of one price, identical goods sold sell for the same price, except for costs associated with those costs reflect and the cost of shipping. according to the law of one price, if the price of a good in one location does not match the price of the same good in a different location, sellers will increase until prices in both locations are equal supply in the location where the good is in different locations less expensive at different times trade barriers production movement between locations currency exchange more expensive

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.
