Lewis (1996). An employee of a multinational company is on loan from the United States to the company’s subsidiary in Europe. During the year, the employee’s financial obligations in the United States (e.g., mortgage and insurance premium payments) amount to $12,000, distributed evenly over the months of the year. The employee can meet these obligations by depositing the entire sum in a U.S. bank prior to departure for Europe. However, at present the interest rate in the United States is quite low (about 1.5% per year) in comparison with the interest rate in Europe (6.5% per year). The cost of sending funds from overseas is $50 per transaction. Determine an optimal policy for transferring funds from Europe to the United States, and discuss the practical implementation of the solution. State all the assumptions.
