Evaluate the set of events below. Determine how the events will impact their respective markets. a. In examining the market for personal computers, a technological improvement reduces the cost of production. The effect of the event will be in . As a result, the equilibrium price will and the equilibrium quantity will . b. In examining the market for smart phones, there is a reduction in the number of sellers. The effect of the event will be in . As a result, the equilibrium price will and the equilibrium quantity will . c. In examining the market for apps for smart devices, there is a tax levied on the sellers of apps. The effect of the event will be in . As a result, the equilibrium price will and the equilibrium quantity will .

One thing to clear ab initio is that equilibrium quantity and price are achieved when the demand and supply curves intersect at a point.  Therefore, at equilibrium, the demand and supply in quantity are equal.

a) If a technological improvement reduces the cost of product, the equilibrium price will reduce and equilibrium quantity will be equal to the quantity demanded and supplied.

b) If there is a reduction in the number of sellers, the equilibrium price will increase and the equilibrium quantity will be equal to the quantity demanded and supplied.

c) If there is a tax levied on the sellers of apps, the equilibrium price will increase and the equilibrium quantity will be equal to the quantity demanded and supplied.

Explanation:

a) The market is in equilibrium when the supply and demand curves intersect, meaning that the quantity demanded and quantity supplied are equal.  The price and quantity at which this intersection occurs are called the equilibrium price and equilibrium quantity respectively.   In economics,  when quantity supplied equals quantity demanded, an equilibrium situation is achieved, and it is represented by this equation: Qs = Qd; where Qs is quantity supplied and Qd is quantity demanded.

b) Equilibrium price reduces when there is a cost reduction and more supplies are pushed to the market to meet demand.

c) When suppliers leave the market, it means that the market price and demand are no longer attractive and beyond their individual influence.  This leads to a reduction in quantity supplied overall.

d) Sales tax increases the price of goods and services, and equilibrium will be achieved when there consumers demand the product with increased price and sellers are willing to produce and sell at such a price.
