Macroeconomics: Cause and Effect Mechanism

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

Economists have created a theory of demand which states the following. Demand curve has a downward slopping which shows the relation between price and quantity while all other factors are equal. At higher prices the demand will decrease, while at lower prices demand will increase.

This causes the price and the quantity move in opposite directions in a supply curve shift. Also, if the quantity supplied decreases at any given price the opposite will happen.

Elasticity : rising or falling price lead changes in quantity of demand, and the quantity of supply and this so-called elasticity

To summarize the concept, when the price of a product falls, the quantity demanded of the product will increase, and conversely, when the price of a product increases, the quantity demanded of the product will decrease, where all other relevant factors are constant. (Glen, 2012).

According to OpenStax, Principles of Economics it can be a change in income, population, tastes, prices of substitutes or complements, or expectations about future prices. All these variables modify the amount of demanded product at all costs. It is possible that the demand curve shifts to the left or the right. The movement to the right happens when the amount of required good is increased at any price compared to the initial position. Conversely, a shift to the left occurs when the amount of demanded good is decreased at all costs compared to the original position.

There are an infinite number of factors that drive economies toward a certain direction. Supply and demand for example, vary with the price of inputs, technology, and decisions made by policy makers to name a few. Depending on the goods, complimentary products or substitutes can change quantity demanded and price. Price elasticity represents the change in demand in relation to the change of price. Quantity demanded is the number of products a person is willing to buy and this directly affects prices causing fluctuations in supply and demand. These wavers between supply and demand are

Changes in demand factors other than price of the good will result in a change in demand. An increase in demand is depicted as a rightward shift of the demand curve. An increase in demand means that consumers plan to purchase more of the good at each possible price. A decrease in demand is depicted as a leftward shift of the demand curve. Income is another factor that can affect demand. If a good is a normal good, increases in income will result in an increase in demand while decreases in income will decrease demand. If a good is an inferior good, increases in income will result in a decrease in demand while decreases in income will increase demand. Other factors affecting supply include technology, the prices of inputs, and the prices of alternative goods that could be produced. An advance in technology, a decrease in the prices of inputs, or a decrease in the prices of alternative goods that could be produced will result in an increase in supply. A deterioration of technology, an increase in the prices of inputs, or an increase in the prices of alternative goods that could be produced will result in a decrease in

Supply and demand regulate the amount of each good produced and the price at which it is sold. It is the conduct of individuals as they work together with one another in aggressive markets. “A market is a group of buyers and sellers of a particular good or service. The buyers, as a group, determine the demand for the product, and the sellers, as a group,

Understanding the fundamental concepts of economics allows us to analyze laws that have a direct bearing on the economy. These laws and theories are essentially the backbone of how economics is used and studied. The law of demand can be expressed by stating that as long as all other factors remain constant, as prices rise, the quantity of demand for that product falls. Conversely, as the price falls, the quantity of demand for that product rises (Colander, 2006, p 91). Price is the tool used that controls how much consumers want based on how much they demand. At any given price a certain quantity of a product is demanded by consumers. As the price decreases, the quantity of the products demanded will increase. This indicates that more individuals demand the good or service as the price is lowered. This can be illustrated using the demand curve. The demand curve is a downward sloping line that illustrates the inversely related relationship of price and quantity demanded.

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.

The demand curve shows what happens to the quantity demanded of a good when its price varies, holding constant all the other variables that influence buyers. When one or more of these other variables changes, the demand curve shifts leading to an increase or decrease in demand. The table below lists all the variables that influence how much consumers choose to buy cigarettes.4

Availability of substitutes: If the price of Coca-Cola was to increase, we can say that a lot of consumers would turn to other kind of soft drinks and that bring a result of the quality demanded of Coca-Cola will decline. But if the price of Coca-Cola falls a lot of consumers will change other soft drinks to Coca-Cola

Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain good producers are willing to supply when receiving a certain price. The correlation between price and how much of a good or service is supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand.
