Economic paper: the role of opportunity cost in financial decision making

Question :

Important conclusion on the role of opportunity cost in financial decision making.

As what I understand from the reading, opportunities cost could be the price that going to pay in the future, in another words, we have to make decision among the alternatives. Although it would be enormous to possess all worthy things, but resources are limited, which allow serving one purpose at one time. Market demand is the key factor to help the management to decide which is the best product or service to implement. In addition, the value of choice should have further benefits and cost relatively. For example, play station games and women magazines are two the most demanding productions; due to the economy crisis, company need to decide cutting back one production (though this is the next best value). As Livingstone (2007) wrote that "Effective management decisions require careful comparison of costs and benefits of alternative action". As a result, play station game shows growth potential and less cost compare to magazines. This could be the better production outcome and reduce unnecessary use of resources.

Please check my grammars and the contents. I am not sure whether i answer the question. Thanks.

There are many grammar errors. I don't understand well enough to tell you if the content is good, but I can correct some sentences:

If I correctly understand the reading, opportunity cost could be the price that one is going to pay in the future; in another words, the cost compared to alternatives.

Although it would be excellent to possess all worthy things, with limited resources we are able to serve only one purpose at one time.

...due to the economy crisis, companies need to decide what productions to cut back (though this is the next best value). As Livingstone (2007) wrote, that "Effective management ...

As a result, play station games show growth potential and less cost compare to magazines.

GOOD LUCK!! This is a hard subject.

"As what I understand from the reading" Is this sentence incorrect???
----- I am trying to express my thoughts after reading the book.

As Livingstone (2007) wrote, that "Effective management ... ( Why can't i use "that" in this sentence?)

Thanks.

No, I think you were trying to say, "From what I understand of the reading..." and the suggestion I offered above was:

If I correctly understand the reading, ...

So, either of those works.

About the other thing... you can write:

As Livingstone (2007) wrote that

or you can write:

As Livingstone (2007) wrote, that

or even:

As Livingstone (2007) wrote, that

but you can't write:

As Livingstone (2007) wrote, that ...

If you do it this last way, the sentence is convoluted...

Like Kevin, I can only guess at your meaning, as a result of unfamiliarity with the subject matter combined with your own propensity for ignoring the rules of English grammar. Here is one possible revision, though:

Opportunities cost is the price one will have to pay in the future when making decisions among various alternative courses of action. Although it would be ideal to pursue all opportunities if one had unlimited resources, this is unrealistic. In real life, market demand is the key factor that helps management decide which is the best plan to implement. Additional cost-benefit analysis should also be carried out. For example, imagine that a company has two major product lines: Playstation games and women's magazines; due to the economic crisis, the company needs to cut back on production of one of these products. Livingstone (2007) writes that "effective management decisions require careful comparison of costs and benefits of alternative action". As a result, the company would conduct research to find out which alternative they should pursue. For instance, research might reveal that Playstation games have higher growth potential and lower production cost compared to the magazines. Thus, cutting the magazine line would be the better production outcome and reduce unnecessary use of resources.
