Perfect Competition是CFA一級中的知識點，在備考CFA考試中你知道這個知識點嗎？今天跟著融躍小編一起看看這個知識點需要掌握哪些？

1、特點

· A large number of independent sellers

· Each firm has relative small market share

· Each seller produces a differentiated product，product differentiation is the most distinctive factors.

· Firms compete on product quality price and marketing

· Firms are free to enter and exit.

· Firms in monopolistic competition face downward-sloping demand curves and the curves are highly elastic because competing products are perceived by consumers as close substitutes.

2、長期均衡和短期均衡

1）Short-run equilibrium：MR=MC.

Because the firm can charge the price determined by the demand curve

2）Long-run equilibrium output is still optimal at MR=MC.

Economic profit will fall to zero，P=ATC

3、在壟斷競爭市場下賺取超額利潤的方法

1）Innovation and product development

· Less-elastic demand curve earn economic profit

· Close substitutes and imitations will eventually erode the initial economic profit;look for innovative product features Continually.

2）Advertising

· High need for firms in monopolistic competition;

· Inform consumers about the unique features of the product;

· Advertising costs are greater and increase the ATC curve

· Output increase;

· If advertising leads to enough of an increase in output (sales) it can actually decrease a firm ’ s average total cost.

3）Brand names

· Provide information to consumer by providing them with signals about the quality of the branded product.
