The effect of changes in price of oil along with subsidy on the price of corn, wheat, and farmland.

Expert Solution & Answer

Explanation of Solution

The effect of changes in price of oil along with subsidy on the price of corn is depicted in Figure 1 using the demand and supply model.

In Figure 1, the horizontal axis represents the quantity of corn, whereas the vertical axis denotes the price of corn.

The effect of changes in price of oil along with subsidy on the price of farmland is depicted in Figure 2 using the demand and supply model.

In Figure 2, the horizontal axis represents the quantity of farmland, whereas the vertical axis denotes the price of farmland.

The effect of changes in price of oil along with subsidy on the price of other agricultural products such as wheat is depicted in Figure 3 using the demand and supply model.

In Figure 3, the horizontal axis represents the quantity of wheat, whereas the vertical axis denotes the price of wheat.

When the oil prices increase simultaneously with the rolling out of subsidy in ethanol production, the demand for ethanol will increase. As the demand for ethanol increases, the demand for corn used for its production also increases. This shifts the demand curve of corn to the right from D₀ to D₁ as in Figure 1. This increases the price of the corn.

As a result of it, the market value of farmland will increase due to the increase in demand for land as depicted in Figure 2 causing the rightward shift of the demand for land from D₀ to D₁ as in figure 2.

From now, more of the farmland would be devoted to the production of corn; less of it would be available for the production of other agricultural products such as wheat. This implies that the supply of wheat would decrease causing a leftward shift of the supply curve from S₀ to S₁ as in Figure 3, thereby increasing the price of wheat.

When the oil prices decreases, the demand for ethanol will decrease. As the demand for ethanol decreases, the demand for corn used for its production also decreases. This shifts the demand curve of corn to the left from D₁ to D₀ as in Figure 1. This decreases the price of the corn.

As a result of it, the market value of farmland will decrease due to the decrease in demand for land for corn production as depicted in Figure 2 causing the leftward shift of the demand for land from D₁ to D₀ as in Figure 2. This decreases the price of the farmland.

From now, less of the farmland would be devoted to the production of corn; more of it would be available for the production of other agricultural products such as wheat. This implies that the supply of wheat would increase causing a rightward shift of the supply curve from S₁ to S₀ as in figure 3, thereby decreasing the price of wheat.

Economics Concept Introduction

Demand: Demand is the quantity of goods and services that people are willing and able to buy at different prices in a given period of time.

Supply: Supply is the quantity of goods and services that people are willing to sell at different prices in a given period of time.

Please read the article attached below titled “Notable & Quotable: Gouging” (March 31, 2020) and answer the given question. Note: The phrase “price-gouging” refers to a situation where some sellers are charging prices (e.g., for health equipment and supplies) that are well above the market price charged by other sellers. If firms are reluctant to raise prices and/or earn an economic profit in response to the coronavirus outbreak, explain why the usual mechanism for achieving “allocative” (or social) economic efficiency in a perfectly competitive industry breaks down. What does Professor Romer recommend to improve “allocative” efficiency during this extraordinary time of a pandemic? In your answer, be sure to explain what economists mean by “allocative” efficiency.

Despondent over the Red Sox's terrible season, Prof. Gruber decides to quit his day job and start a bicycle manufacturing firm in Kendall Square. As he starts looking into the bicycle manufacturing industry, he realizes it has some interesting features. First, he realizes that it operates as a competitive industry. Second, he finds that there are two technologies used by firms in the industry. Technology 1 uses solar power, and has a cost function C1(q)=q+4Q2+32 for q>0. Technology 2 uses electricity from the grid and is more efficient, with a cost function C2(q)=q+2Q2+32 for q>0. Assume that we are in the long run, so firms using both technologies can shut and leave the market at 0 cost, so that C(0)=0 for both technologies. Now, suppose that the government of Massachusetts offers solar subsidies to 10 bicycle manufacturers. These subsidies are for $80 and the manufacturers receive these subsidies as long as they construct a bicycle manufacturing plant using the newly-invented…

Milly and Rob are the only two growers who provide organically grown corn to a local grocery store. They know that if they cooperated and produced less corn, they could raise the price of the corn. If they work independently, they will each earn $100. If they decide to work together and both lower their output, they can each earn $150. If one person lowers output and the other does not, the person who lowers output will earn $0 and the other person will capture the entire market and will earn $200. The table represents the choices available to Milly and Rob. What is the dominant strategy for Milly ? Milly Keeps Producing Milly Lowers Output Rob Keeps Producing $100, $100 $200, $0 Rob Lowers Output $0, $200 $150, $150 Group of answer choices Milly should keep producing Milly should work independently from Rob Mily should lower output
