Answer on Economics of Enterprise Question for mohamed
Why invest capita in purely competitive industries with equilibrium margins that are razor thin and entrants that erode quasi profits? Suppose volume is not exceptionally large, why then?
Purely competitive firms are price takers, price is equal to marginal costs, demand is perfectly elastic, i.e. constant and horizontal, the firms make small or zero economics profits. There is a sense, because you will earn small, but profit with the small risks, the market is efficient, there is no deadweight loss, and the competition itself leads the firms to create innovations, to decrease costs and to produce more efficient goods.
I'm extremely impressed with your work. In fact, I am likely going to change major to computer science from next semester. Before turning to you for help, I thought its all over and there is simply no one who can offer expert programming help. I had no hope at all. My experiences with other sites were horrible.
By chance I contacted you about 7 months back and it was amazing when I looked at your work. From thereon, I decided to rely on you only.
