Best Answer

The supply and demand curve follows four basic laws :

  1. If demand increases (demand curve shifts to the right) and supply remains unchanged, a shortage occurs, leading to a higher equilibrium price.
  2. If demand decreases (demand curve shifts to the left) and supply remains unchanged, a surplus occurs, leading to a lower equilibrium price.
  3. If demand remains unchanged and supply increases (supply curve shifts to the right), a surplus occurs, leading to a lower equilibrium price.
  4. If demand remains unchanged and supply decreases (supply curve shifts to the left), a shortage occurs, leading to a higher equilibrium price.

Which way will an increase in labor cost shift the supply curve?

An increase in labor cost will decrease supply, so the supply curve will shift left.


What happens to the supply curve when there is a decrease in production?

Then the price will increase.


What causes a shift in the supply curve?

the factors that cause the demand curve for bonds to shift are: increase/decrease in inflation rate increase/decrease of common stock increase/decrease of stock prices useful table :


What happens to a supply curve when there's a decrease in production?

Price will increase as less products are available.


What are factors affecting supply curve?

A change in supply (a shift in the supply curve) occurs whenever some factor that affects the supply of the good, other than its price, changes. Such variables include:1. Prices of productive resources. A rise (fall) in the prices of resources shifts the supply curve leftward (rightward).2. An increase in technology shifts the supply curve rightward.3. An increase (decrease) in the number of suppliersshifts the supply curve rightward (leftward).4. Prices of other goods produced, which have two possible relationships:a) When the price of a substitute in production rises (falls), the supply curve for the good shifts leftward (rightward).b) A rise (fall) in the price of a complement in production shifts the supply curve rightward (leftward).5. If the expected future price of the product rises (falls), the supply curve in the present period shifts leftward (rightward).A change in supply also affects the price and quantity of the product.1. An increase in supply (a shift rightward of the supply curve) causes the price to fall and the quantity to increase.2. A decrease in supply (a shift leftward in the supply curve) causes the price to rise and the quantity to decrease

If the demand for a product remains the same and the supply increase what will happen to the equilibrium price?

If there is an increase in supply, the supply curve will be shifted to the right. This leads to a decrease in the equilibrium price and an increase in equilibrium quantity. This is easy to see if you draw it out.


What are the basis of an increase or decrease in supply?

demand in supply is the basis of it's increase and decrease


Is An increase in supply is represented by a movement up the supply curve?

An increase in the supply is not represented by a movement up the supply cuve. A movement up supply curve is due to the increase in quantity supplied instead of the increase in supply. Alternatively, it can also be due to increase in the price of the goods that could lead to movement up the supply curve.


Which direction would the supply curve shift if there was a decrease in supply?

leftward


What effect does an increase in the money supply have on inflation?

An increase in the money supply shifts the money supply curve to the right. If you look on your graph, you will see that an increase in money supply will cause the interest rate to decrease. Here's why: Fed increases money supply-->excess supply of money at the current interest rate -->people buy bonds to get rid of their excess money-->increase in the prices of bonds --> decrease in the interest rate.


A decrease in supply is represented by?

Shift of the curve to the left.


How will increase in the price of a substitute good shift the demand curve?

An increase in the price of a substitute good will increase demand for the original good, thus shifting the demand curve to the right.
