What are the key factors that influence the decline of traditional retail businesses in the digital economy?  2. How does consumer behavior impact the success or failure of legacy retail brands?  3.

How can traditional retailers effectively adapt their business models to meet evolving market demands?
Problem 1.1 Cyber security is a very costly dimension of doing business for many retailers and their customers who use credit and debit cards. 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?
