To spur trade, four South American countries decide there will be no barriers to trade between the countries, agree on a common

Dmitriy789 [7]

Answer:

A free trade area

Explanation:

A free trade area comes to existence when two or more countries sign an agreement that eliminates or reduces trade barriers among themselves. Usually, nations in the same region sign a free trade agreement that encourages economic cooperation. In a free-trade area, goods and services can move from one country to another with minimal or no government interference in terms of tariffs, embargo, quotas, or other prohibitions.

The four South American countries have formed a free trade area. They have agreed to economic cooperation that allows free flow of trade among the nations. The countries have established a trading block that will spur economic growth in each of them.

As a general rule concerning job offers, it can be said that __________. select one:

AlladinOne [14]

As a general rule concerning job offers, it can be said that <span>"competitive" job offers tend to leave room to negotiate</span>. When a company decides they want to hire a person, they make a job offer that lays out what they are giving the person in return for their employment. They explain the benefits and their job duties. Because job offers are competitive they leave room for the person being hired to negotiate terms before they both agree on them.

Suppose that the demand for steel in Japan is given by the equation Qd S = 1200 – 4PS + PA + PT, where QS is the quantity of ste

timurjin [86]

Answer: See explanation below for answer.

Explanation:

a) In equilibrium the quantity supplied will equal the quantity demanded in all three markets. Algebraically this implies:

Qd S = Qs S

Qd A = Qs A

Qd T = Qs T

Substituting in the given curves implies:

1200 - 4PS + PA + PT = 4PS

1200 - 4PA + PS + PT = 4PA

1200 - 4PT + PS + PA = 4PT

Solving the first equation for PT and substituting into the second equation implies:

1200 - 4PA + PS + (8PS - PA - 1200) = 4PA

9PS = 9PA

Cancel 9 on both sides, we have:

=> PS = PA

Substituting these results into the third equation implies:

1200 - 4(8PA - PA - 1200) + PA + PA = 4(8PA - PA - 1200)

=> 10800 = 54PA

=> PA = 200

At:

PA = 200

PS = 200

PT = 200

The equilibrium quantities are:

QA = 800

QS = 800

QT = 800

b) Substituting the new supply curve for steel into the equilibrium condition, we have:

1200 - 4PS + PA + PT = PS

1200 - 4PA + PS + PT = 4PA

1200 - 4PT + PS + PA = 4PT

Again solving for PT in the first equation and substituting into the second equation, we have:

1200 - 4PA + PS + (5PS - PA - 1200) = 4PA

=> 6PS = 9PA

=> PS = 1.5PA

Substituting these results into the third equation, we have:

1200 - 4(5(1.5PA) - PA - 1200) + 1.5PA + PA = 4(5(1.5PA) - PA - 1200)

=> 10800 = 49.5PA

=> PA = 218.18

At:

PA = 218.18

PS = 327.27

PT = 218.18

At these prices, the equilibrium quantities are:

QA = 872.72

QS = 327.27

QT = 872.72

The shift in the supply of steel raises the equilibrium price for all three goods, lowering the equilibrium quantity of steel and raising the equilibrium quantities of aluminum and titanium. This last effect comes as a result of the demand curves for aluminum and titanium increasing in response to the shift in the steel supply curve.

c) Returning to the original equilibrium, this shift in the demand for aluminum implies:

1200 - 4PS + PA + PT = 4PS

1500 - 4PA + PS + PT = 4PA

1200 - 4PT + PS + PA = 4PT

Solving the first equation for PT and substituting into the second equation, we have:

1500 - 4PA + PS + (8PS - PA - 1200) = 4PA

=> 9PS + 300 = 9PA

=> PS = PA - 33.33

Substituting these results into the third equation, we have:

1200 - 4(8(PA - 33.33) - PA - 1200) + (PA - 33.33) + PA = 4(8(PA - 33.33) - PA - 1200)

=> 12900 = 54PA

=> PA = 238.89

At:

PA = 238.89

PS = 205.56

PT = 205.56

At these prices, the equilibrium quantities are:

QA = 955.56

QS = 822.24

QT = 822.24

An increase in the demand for aluminum will raise the equilibrium prices and quantities in all three markets. The price and quantity in the steel and aluminum industries increase because as the price of aluminum rises, the demand for steel and titanium increases.

Mary manages a data entry center. Workers sometimes play games on the internet, check their personal email, or go slow. Accordin

telo118 [61]

Answer:

Mary could increase the wages of the workers above the market rate.

Explanation:

The efficiency wage theory aims at ensuring high productivity level in a company by increasing the wages of it's employees above the market rate. It has been proved that an increase in wages transfer directly to the productivity levels of the employees. This is due to a number of reasons as show;

1. Fear of losing jobs: if Mary increases the wages of her employees above the average market rate, the employees will feel that they need to retain their job since the financial benefits they get from Mary's company is better than other companies. This improves increases their motivation to be productive, since the other alternatives are not so attractive.

2. Loyalty: an increase in the wages of employees make them feel appreciated and might want to work harder as opposed to feeling exploited in a company that pays them considerably less wages.

3. Lower costs of supervision: it has been proved that increasing the wages of employees makes them have a sense of responsibility since they feel like appreciated. The employees in such a case will need minimal supervision to carry out their duties.

4. Attract higher quality labor: a company that pays higher than the market rate will more often than note attract high quality labor as a show of gratitude for the wages.
