In class we talked about a number of different welfare measures. a) Graphically identify twoalternative money measures of welfare for an imposed change in the level of an environmental service flow (S1 > S0). b) Discuss the pros and cons of the measures you demonstrated above c) Distinguish between the compensating and equivalent measures using both expenditure and indirect utility function approaches. Explain the difference between the two in words.

Expert Solution

answer..a

Two alternative measure of welfare in a society can be identified as the GDP of the country and the Health index of the common people.

As we can see from the graph above, the GDP1 curve is the GDP of the last year and the curve GDP2 is the GDP of the current year. If, like as in the graph above, the GDP curve moves ahead, we can conclude that the GDP rate of the country has been positive and better than the last year.

Similarly, the H1 curve is the Health index of the last year and the curve H2 is the Health index of the current year. If, like as in the graph above, the Health index curve moves below, we can conclude that the Health index rate of the country has been negative and poorer than the last year.

Answer (b) : The positives of the measures demonstrated are many , like, the GDP is the figure that is the final index of the overall development of an economy. If GDP is positive, it would imply that economy has actually overall performed better. Moreover, GDP shows us the overall position of a country’s development in perspective with other countries, which helps the economy to perform better by rectifying the ill economic happenings. Similarly, the Health index of a nation shows us, how well the people of a country stay. If the country has a positive health index, the country is improving in its health sector and lesser citizens are prone to ill health.

However, the GDP measures the overall development of an economy. It can never calculate the economic condition of the poorer section of the society, as GDP even shows increasing when the condition of the poor remain the same or even worsen off. This is because, GDP never measures the mental utility of social utility if a nation. Similarly, the Health sector only calculates the health index out of the total reported cases in the medical centers. Those cases, which have never been reported are never brought under calculation.

Answer ( c) : Compensating variation refers to the change in a consumers utility that needs to be reverted back to reach back to a point of the consumers initial utility. The variance to reach back to the original state of utility is called compensating measures. Adjustments made in the expenditure to reach up to the new utility can be easily reverted back by paying back off the expenditure made by the consumer, so that he goes back to the original state of utility. However, the indirect utilities cannot be physically measured.

Whereas, equivalent variation of measure relates to the change in the consumers overall satisfaction due to an increase in the consumers price level. If a consumer receives a higher pay out and hence his utility rises, this is referred to as an equivalent measure. In this type of measure, the measurement of the customers utility is easier , as here the base of the utility change is price and can easily be reverted if the need be.

Below is the pseudocode for Quicksort and Partition that we talked about in class. As usual with recursive functions on arrays, we see the array indices s and e as arguments. Quicksort(A, s, e) sorts the part of the array between s and e inclusively. The initial call (that is, to sort the entire array) is Quicksort(A, 0, n − 1) QuickSort(A, s, e) if s < e p = Partition (A, s, e) // Partition the array and return...

In class we talked about the effects of cigarette smoking on birthweight. We defined a model E ( O | C = c ) = (β0)^1 + ((β1)^1 x c) where O is birthweight in ounces and C is cigarettes smoked per day. Suppose instead we used the model E(L|P =p)=(β0)^2 +((β1)^2 x p) where L is birthweight in pounds and P is packs of cigarettes smoked per day (there are 20 cigarettes in a pack). What is the relationship...

We talked about a diversity of respiratory strategies used by animals in class. One of the main differences between fish & frogs compared to reptiles, and mammals was that fish and frogs use buccal pumps and reptiles and mammals use suction pumps. How do buccal and suction pumps differ (please refer to where volume and pressure is changed and how it moves the respiratory medium through the respiratory system)? Explain how frogs use buccal pumps and mammals use suction pumps...

We talked in class about how some textbooks tell us that the way to conduct a cost benefit analysisassociated with a policy is to look atthe costs and benefits beforea policy was put in place and compare them to the cost and benefits after the policy is in place. Is this correct? If so, explain why. If not, explain why not. NOTE: I realize that you should say "with" or "without" the policy, NOT "before" and "after" but I don't...

Throughout the semester we talked about the challenges that different groups of organisms had to overcome as they evolved to live in terrestrial environments. What do you see as the biggest obstacles that different groups of organisms had to overcome as they evolved to live on land? Describe ways in which different groups (including plants, arthropodsand vertebrates) were able to meet these challenges. (20 pts)

In class, we talked about the elements for an effective signal. Courting male peacock spider Describe the all of the components of this display. What modalities of communication might be in use (e.g. visual, etc.)? Write and explain hypotheses for the following questions: a. What makes this signal conspicuous? b. What information might the male be trying to convey to potential mates? How would you test for this? c. What might ensure that these signals are reliable and honest? d....

We have talked in class about second order differential equations. These equations often arise in applicationsof Newtons second law of motion. For example, supposeyis the displacement of a moving object with massm. Its reasonable to think of two types of time-independent forces acting on the object. One type - suchas gravity - depends only on positiony. The second type - such as atmospheric resistance or friction -may depend on position and velocityy′. (Forces that depend on velocity are called damping...
