What is It About Graphs in Economics? Essay

Any change that lowers the quantity that buyers wish to purchase at any given price shifts the demand curve to the left.

|Event |Market affected by event |Shift in supply, demand, or both. |Change in equilibrium |

|Event |Market affected by event |Shift in supply, demand, or both. |Change in equilibrium |

If we consider this supply and demand diagram prior to Government intervention (red line), the market leads to equilibrium price and quantity (P1, Q1) determined at the intersection of the supply (or MPC) and demand curve. Due to the

Apple juice and orange juice are substitutes for consumers, so the fall in the price of apple juice decreases the demand for orange juice. The demand curve for orange juice shifts leftward. The increase in the wage rate paid to orange grove workers raises the cost of producing orange juice. The supply of orange juice decreases and the supply curve of orange juice shifts leftward. The net effect of these events decreases the equilibrium quantity but has an undetermined effect on equilibrium price. If supply decreases by more than the demand, the shift in the

2.) Which curve(s) change and based on the lists in the text of what causes demand and supply to shift what are the causes of theses shifts? D1 changed moving leftward indicating a decrease in demand due to a technological change: a technological setback causes a decrease. This causes price to go down as well as the demand is lower.

Supply is the total amount of a specific good that is available to the consumers. The supply of lobsters depends on the ocean temperature and since the ocean temperature is increasing, lobsters may once again come in a couple more weeks earlier than usual. In 2012, this caused the quantity of lobster to increase significantly, thus the supply curve shifted to the right. The shift caused the equilibrium price to decrease and the quantity to increase. On the other hand, if the ocean temperature is too low, then the lobster production rate is lowered. The supply curve will then shift to the left and cause the equilibrium price to increase and the quantity to decrease. The lobsterman cannot control the supply of lobsters since the production depends on the temperature. Another economic topic that came to my mind is the demand of a product. Demand is a consumer’s willingness to pay a price for a specific good. The demand curve would shift to the right if the price of the lobsters decreases due to mass production and vice

2. The key economic concept that serves as the basis for the study of economics is:

The market price of a good is determined by both the supply and demand for it. In the world today supply and demand is perhaps one of the most fundamental principles that exists for economics and the backbone of a market economy. Supply is represented by how much the market can offer. The quantity supplied refers to the amount of a certain good that producers are willing to supply for a certain demand price. What determines this interconnection is how much of a good or service is supplied to the market or otherwise known as the supply relationship or supply schedule which is graphically represented by the supply curve. In demand the schedule is depicted graphically as the demand curve which represents the

For instance, if someone's income grows, then his demand for goods will increase, shifting his demand curve to the right. This will lead to a higher quantity being consumed at a higher price, ceteris paribus. Conversely, there can be a negative effect that shifts the supply curve to the left where a lower quantity is consumed at a lower price, ceteris paribus. This can occur when the price of substitutes falls or consumers begin to lose their taste for the product.

22) The above figure shows a graph of the market for pizzas in a large town. At a price of $14, there will be A) no pizzas supplied. B) equilibrium. C) excess supply. D) excess demand. Answer: C 23) The above figure shows a graph of the market for pizzas in a large town. At a price of $5, there will be A) excess demand. B) excess supply. C) equilibrium. D) zero demand. Answer: A 24) The above figure shows a graph of the market for pizzas in a large town. What are the equilibrium price and quantity? A) p = 8, Q = 60

This is a perfect example of a change in demand; when the demand increases, at the same or even a higher price, more quantity is demanded. In the figure below, a shift to the right in the demand curve signifies an increase in demand.

An example of demand curve shifting. The shift means an increase in demand with consequences for the other variable.

Figure 2 demonstrate how any change in one of the other determinants causes demand to rise or to fall by shifting the whole curve to the right or the left. Other factors that determinates of demand

Using appropriate diagrams, discuss how an increase or an improvement in the following non-price determinants of supply would change equilibrium prices and quantities.
