1. Exchange-rate fluctuations and international competitiveness Comdemo is a hypothetical U.S. computer manufacturer. The following table shows Comdemo's production costs of producing one computer. Note that Comdemo denominates the costs of its inputs in dollars as well as francs. Initially, in period 1, the exchange value of the dollar is $0.50 per franc. Complete the Period 1 section in the following table by calculating the franc equivalent of the input costs and Comdemo's total cost of producing one computer. Cost of Producing One Computer Period 1: $0.50 per Franc Cost (Dollar) 150.00 120.00 Labor Dollar-denominated inputs Franc-denominated inputs 150.00 Energy cost 90.00 Total cost 510.00 Equivalent (Franc) 300.00 240.00 180.00 Period 2: $0.40 per Franc Cost Equivalent (Dollar) (Franc) 150.00 375.00 120.00 Suppose that in period 2, the dollar appreciates to $0.40 per franc. 90.00 300.00 225.00 Complete the "Period 2" section in the previous table by calculating the franc…
