Farmville gameis a very popular online game and there are many crazy fans glued to this game 24/7. Here are a few hints which could help you play this interesting game strategically.

First of all, to play Farmville you will have to make friends who are also members of this game and play them regularly. One can only hope to increase his farm and to have a dream farm if you have good neighbors in you Farmville account. Even if your friends are not interested in playing Farmville you can just send them Farmville request and tell them to accept it as it will increase your points and you can increase you neighbors through which you can increase you farm to a good extent.

Once you are successful in having many neighbor friends in your Farmville, you must make sure that you benefit them and also are benefitted from them. You can just click on the my neighbors option present in this game and then visit you neighbors to know if any of your neighbor friend requires any type of help. If anyone does then you can help them. On helping them you can increase your experience points. Thus, this is a great way to help you increase you points. However you must always aim to earn ribbons as they form the basis of Farmville. However Farmville gets the most interesting when you plow, harvest and then plant good seeds. Plants which take longer time to grow will last for a longer time. Hence, this would be a good choice of seeds that need to be planted by you.

These are just the basics of Farmville that every new comer or rather new farmer should make note of. Once you have got the hang of it, slowly and steadily you might discover several new tips and tricks by the help of which you will be a great farmer in no time.

Question three:

What is the external cost per unit of output?

Social cost is equal to private cost plus external cost, in this case we are given private and social costs and therefore we can derive external costs as follows:

Quantity

Private Cost

Social Cost

external costs

1

$2

$4

$10

$12

$18

$20

$28

$8

$30

$40

$10

What level of output will be produced?

Production will be at the point that maximizes profits; this point will be where marginal cost equal marginal revenue, marginal cost in this case will be the marginal private cost, and marginal benefits will be marginal revenue, the following table summarizes the values:

The chart below sumarises the values

Therefore production will be 3.5 units

What level of output should be produced to achieve economic efficiency?

We introduce the marginal social costs into the chart and the point where marginal cost curve is equal to marginal benefits is the economic efficient production point, the chart below shows the marginal curves:

Therefore the economic efficient point of production is 3 units.

d. What is the value of society of correcting the externality?

To correct externalities the production level will decline from 3.5 to 3 units, therefore the society will produce less by 0.5 units, this is the level that the society has to pay to correct externalities and therefore pay for the extra costs not incurred.

Question # 4 – What level of tax would be appropriate to internalize the externality in exercise 3?

Private cost should be equal to social cost, the current production level is 3.5 units

The private cost is $15, the social cost at this point is $22.5, the external cost here will be equal to 22.5 – 15 = $7.5, the best tax rate should be 7.5/15 X 100 = 50%, therefore a 50% tax will make social cost to be equal to private cost.

Question # 5 – If, in exercise 3, the Private Cost and Social Cost columns were reversed, you would have an example of what? Would too much or too little of the good be produced? How would the market failure be resolved, by a tax or by a subsidy?

If we reverse the private cost and the social costs we will have positive externalities, this is where the social costs will be lower than the private costs, for this reason therefore to resolve this market failure there will be a need to subsidies production in order to produce more to benefit from positive externalities, In this case too little of the good will be produced therefore a subsidy will be used to improve on the market failure.

Chapter 15 Questions

Question # 6 – Suppose the resource price rises from $10 to $12 to $14 to $18 to $20 as resource units go from 1 to 5.

Question # 7 – In question 6, calculates the transfer earnings and economic rent of the third unit of the resource when four units of the resource are employed. Do the same calculations when only three units of the resource are employed. How do you account for the different answers?

When 4 units are employed it is required that $40 are payed for the resources, however the amount paid is 18 X 4 = 72, therefore the economic rent for the four untis is $32, for the 3rd unit the economic rent is 32/4 = 8, therefore for the third unit the economic unit is 24, transfer earnings is equal to 32 – 24 = $8.

If three units are employed then $42 is paid and only 30 should be paid, in this case therefore the economic rent is $12. Economic rent occurs when there is imperfect competition in the market; this can be because of monopolistic form of market.

C14 – How would your neighbor loudly playing a stereo exemplify a negative externality? Explain

Externalities are experienced when the production process fails to record all costs or benefits. Negative externalities occur when the production process will not record all costs in production. In the case of loud music by a neighbor this will lead to negative externalities, externalities will be realized as a result of noise pollution, a neighbor may want to study but due to the loud music may fail to concentrate, the neighbor may play loud music at night and this may make his or her neighbors to have sleepless nights, therefore loud music by a neighbor will be regarded as a negative externality.

C15 – How would you compare wages earned in the private sector with wages earned in the public sector? Why the difference?

There may be market failure and the government may intervene to improve on such a situation, however the government may cause harmful interference in the market but this does not mean that the government should not intervene. In a free market the price for products and factors of production are determined by the supply and demand, the private sector is a free market and therefore will offer wage rates determined by the supply and the demand. In the public sector the wage rate is adopted by a government or from the market, for this reason therefore the public sector wages will be different from private sector wages in that in the private sector the wage rates are determined by demand and supply why the government will only adopt a wage rate to pay its employees.
