In 2010, an explosion on a BP oil rig in the Gulf of Mexico caused loss of life and grave environmental consequences for the surrounding area. In response, BP worked to clean up the area, compensated people affected by the impact of the accident, and supported the economic recovery of Gulf Coast tourism and seafood industries impacted by the oil spill. BP has also committed funding for independent research on the Gulf of Mexico ecosystem so it can better understand and mitigate the potential impacts of oil spills. In short, BP exhibited: a. corporate social responsibility.
b. environmentalism.
c. green marketing.
d. shareholder responsibility.
e. sustainable marketing.

Suppose that two firms produce differentiated products and compete in prices. as in class, the two firms are located at two ends of a line one mile apart. consumers are evenly distributed along the line. the firms have identical marginal cost, $60. firm b produces a product with value $110 to consumers.firm a (located at 0 on the unit line) produces a higher quality product with value $120 to consumers. the cost of travel are directly related to the distance a consumer travels to purchase a good. if a consumerhas to travel a mile to purchase a good, the incur a cost of $20. if they have to travel x fraction of a mile, they incur a cost of $20x. (a) write down the expressions for how much a consumer at location d would value the products sold by firms a and b, if they set prices p_{a} and p_{b} ? (b) based on your expressions in (a), how much will be demanded from each firm if prices p_{a} and p_{b} are set? (c) what are the nash equilibrium prices?
