What happens to an incumbent firm's demand curve in monopolistic competition as new firm enter:

Price elasticity of demand measures the responsiveness of the quantity demanded to:

  • Quantity x Demand
  • Quantity x Supply
  • Output
  • Production



A)Define equilibrium?
B)Suppose quantity demanded and Qs od a cane of soap is described by the following equation:
Qd=1000-200p
Qs=300+150p
I)What is the quantity of soap?
II)if the price of soap is $3.00 per cane, will there be a surplus or shortage? what would be the size of surplus or shortage? (2+4+4)

Define equilibrium. Qd=100-10p find price =? Qs=40+2p (10)

A market is said to be in equilibrium when:

  • Demand equals output
  • There is downware pressure on price
  • The amount consumers wish to buy at the current price equals the amount producers wish to sell at.
  • All buyers are able to find sellers willing to sell to them at the current price.


Price floor results in:

  • Excess supply
  • Equilibrium
  • Excess demand


For calculating price elasticity of supply, you need to know

Assume that one of two possible outcomes will follow a decision. One outcome yields a $75 payoff and has a probability of 0.3, the other outcome has a $125 payoff and has a probability of 0.7. In this case the expected value is:

What is the advantage of the standard deviation over the average deviation?

Because the standard deviation requires squaring of deviations before further computation, positive and negative deviations do not cancel out.
Because the standard deviation does not require squaring of deviations, it is easy to tell whether deviations are positive or negative.
The standard deviation expresses the average deviation in percentage terms, so that different choices can be more easily compared.
The standard deviation transforms subjective probabilities into objective ones so that calculations can be performed.
