论文代写：市场势力如何决定均衡价格与数量
可以看出，在上面的图中，在0p1价格水平，供给量（0q1）正在超过需求量（0q2）。因为在市场上提供的商品数量有限，买家之间产生了竞争，这就意味着消费者会对价格进行竞价。在需求和供应由于在价格上升膨胀收缩；这也意味着对平衡点有沿曲线运动（burfisher，2011）。只要有超额需求，这将继续发生。在一段时间内，出现了一种情况下的需求和供给曲线的交点发生。正是在这一点上，消费者需求量正好等于在0qe水平供给量和价格水平0PE。
因此，出现了一种情况，被称为在市场上的供过于求或过多的供应。卖方可以以较低的价格出售，以消除供应过剩。由于价格下降，供应收缩，这也是一种需求的扩张，而这也是一个最佳点附近曲线的运动。只要市场有供应过剩，这将继续发生，直到我们在供给和需求曲线相交。这是在0PE价格水平，需求量和供应量等于市场出清本身。
论文代写：市场势力如何决定均衡价格与数量
It can be seen in the above figure that at the price level of 0P1, the quantity supplied (0Q1) is being exceeded by the quantity demanded (0Q2). For the limited quantity of goods which are available in the market there arises a competition amongst the buyers; this means that there would be bidding up of the prices by the consumers. There is a contraction in demand and an expansion in supply due to the rise in the prices; this also means that towards the equilibrium point there is a movement along the curves (Burfisher, 2011). As long as there is excess demand this will continue to occur. Over a period a time, there comes a situation where the intersections of the demand and supply curves occur. It is at this point that where the quantity demanded by the consumers is exactly equal to the quantity supplied at the 0Qe level and the price level is 0Pe.
Hence, there arises a situation which is known as glut or excess supply in the market. Seller would offer to sell at a lower price in order to remove excess supply. There is an expansion of demand because of fall in price and leading to contraction in supply which is also the movement alongside the curves near the optimal point. As long as there is excess supply in the market, this would continue to occur till we are at the point where supply and demand curve intersects. This is at 0Pe price level where the quantity demanded and supply is equal and market clears itself.
