economic income

In calculating economic income I know we need to calculate the gain or loss year over year…but my question is: is the gain or loss in the very 1st year of the project get calculated as:

cost-new market value=gain or loss

originally calculated market value- new market value= gain or loss…

I feel like I’ve come across some problems that use the original market value as cost- but other seem to make me calculate NPV at t=0 and use that??

thnx!

Economic income is the difference between the beginning of period market value and end of period market value.

Beg. Period market value is calculated as the present value of cashflows including the current period cashflow.

End of period is calculated as the present value of cashflows excluding the current period cash flow.

I think could be wrong. Havent gone through Corp. In a while.

the question is- if they give you a market value at time t=0 do you use that or do you calculate an ‘intrinsic’ market value based on the remaining cash flows?

I think theoretically those intrinsic and the market value should to the same.

But the way I have seen it, the question usually requires you to find the difference between the intrinsic values.

Can you post the question if possible?

i think I’ll just hope to God that those would be the same on exam day haha kind of a little detail here not anything to worry about…
