8. Two software companies sell competing products. These products are substitutes so that the number of units that either company sells is a decreasing function of its own price and an increasing function of the other product's price. Let P1 and X1 be the price and quantity sold of product 1, and P2 and X2 the price and quantity sold of product 2. We have that X1 = 1,000 90-P1+P2) and X2 = 1,000 90P2+P1).

(d) Suppose that company 1 sets its price first. Company 2 knows the price P1 the
company has chosen, and it knows that company 1 will not change its price. Also,
company 1 is aware of how company 2 will react to its own choice of price. Explain
and calculate the prices of the two companies and their total revenues. Comment on
whether there is a first or second mover advantage in this model in terms of the size
of the change in the total revenue of each company relative to its total revenue in the
simultaneous price setting game.
