Recent research indicates potential health benefits associated with coffee consumption, including a potential reduction in
the incidence of liver disease. Simultaneously, new technology is being applied to coffee bean harvesting, leading to cost
reductions in coffee production. How will these developmentsaffect the demand and supply of coffee? How will the
equilibrium price and quantity of coffee change? Use both words and graphs to explain.

A recent data breach of U.S.-based Home Depot involved some 56 million cardholders. Just to investigate and cover the immediate direct costs of this identity theft amounted to an estimated $62,000,000, of which $27,000,000 was recovered by insurance company payments. This does not include indirect costs, such as, lost future business, costs to banks, and cost to replace cards. If a cyber security vendor had proposed 8 years before the breach that a $10,000,000 investment in a malware detection system could guard the company's computer and payment systems from such a breach, would it have kept up with the rate of inflation estimated at 4% per year?arrow_forward

As a result, Everglades produces 12 million pairs of shorts and 16 million pounds of almonds, and Denali produces 5 million pairs of shorts and 30 million pounds of almonds. Assume there are no other countries willing to engage in trade, so, in the absence of trade between these two countries, each country consumes the amount of shorts and almonds it produces.
