Undercoverage bias occurs when some members of the population are inadequately represented in the sample. I am not 100% but this should be right.
D. The equilibrium quantity would increase, and the effect on equilibrium price would be ambiguous.
Explanation: It follows that the quantity of latte produced would increase given that the newly introduced machine reduces the amount labour required and also is more efficient. Therefore more quantities of latter will be produced in short periods. Same thing would occur when it is discovered that the coffee used in producing lattes prevent heart attacks.
In both instances, the equilibrium quantity increases. However, equilibrium price is ambiguous, this is because the discovery that coffee prevents heart attacks would serve to push up prices of latte since suppliers would want to cash in on that, while the use of machines would push price down as a result of mass production.
Increase in equilibrium quantity of fish.
Explanation: New technology allows fishing boats to catch more fish while using the same number of crew-members. This will increase supply of fish shifting the supply curve for fish to the right.
At the same time a new study shows that eating fish at least three times a week helps prevent heart attacks. This will increase demand for fish shifting the demand curve for fish to the right.
The net effect of these changes is an increase in equilibrium quantity of fish. However, the change in the price of fish cannot be determined as it depends on the magnitude of shift in the two curves.
Option (a) is correct.
Advanced technology is a determinant of supply and consumer taste & preferences is a determinant of demand.
Therefore, improvement in technology in catching fish will lead to increase the supply of fish and this will shift the supply curve rightwards. On the other hand, eating fish prevents heart attacks, hence, consumer's demand for fish increases, as a result demand curve for fish also shifts rightwards.
This will lead to increase the equilibrium quantity but effect on equilibrium price is ambiguous because it will be depend upon the magnitude of the shifts of demand and supply curve.
The equilibrium quantity would increase, and the effect on equilibrium price would be ambiguous
Explanation: If latte shops begin to use machines that reduces the amount of labour required to make an essential ingredient of the coffee latte, it means that the quantity produced at equilibrium would increase. This would also be the case it is found that coffee prevents heart attacks. The demand for the Finished product (latte) would increase, leading to increased production and supply. Therefore, in this scenario, equilibrium quantity increases.
The effect on equilibrium price would be ambiguous due to the fact that the discovery of coffee preventing heart attack would raise the equilibrium price; while the ease of production using a machine would act to decrease it.
.d. The equilibrium quantity would increase, and the effect on equilibrium price would be ambiguous.
The use of the machine would increase the supply of lattes and price falls. The supply curve would shift to the right. If scientists discover that coffees reduce heart attack, the demand for coffee would increase and price would increase. The demand curve would shift to the right.
The combined effect would be a rise in equilibrium quantity and an indeterminate effect on equilibrium price.
I hope my answer helps you
Dont eat so many fatty foods
Stop drinking to many sugary drings and alcohol
Stop taking drugs
Live a healthy lifestyle and get into good habits and not bad
Equilibrium price = Ambiguous change
Equilibrium quantity = Increases
Rightward shift of supply curve:
If there is an improvement in the technology of catching fish then this will lead to increase the productivity of the fisherman. Since, there is an increase in the productivity of the fisherman which will increase the supply of fish in the fish market and shifts the supply curve rightwards.
Rightward shift of demand curve:
If people came to know that eating more fish helps in preventing heart attacks. So, this will induces people to buy and demand more fish. Hence, there is a rightward shift in the demand curve of fish in the fish market.
These shifts in the supply and demand curve will increase the equilibrium quantity of fish and the impact of these shifts on equilibrium price is ambiguous because that will be dependent upon the magnitude of the shifts of demand and supply curve.
Option A, Equilibrium quantity will increase but the effect on the equilibrium price is unknown without more information, is the right answer.
Option A is correct because the change in technology allows the person to catch more fish with the same crew. Thus, this will increase the supply, and the supply curve will shift rightwards. Moreover, the new study shows that a reduction in heart attack will cause an increase in the demand for fish. So the demand curve will shift rightwards. Here, we can see the increase in equilibrium quantity but we can not explain the effect on price due to lack of information. Therefore, option A will be right.
