Consider a manufacturing industry that exports its output by ship. Each firm has total revenue per month of $1,400 and a monthly nonland production cost of $400. Each firm initially transports its output from its factory at location x to the port (x 5 0) on trucks. A ?rms freight cost is $100 per blo
