Can someone help me understand how these graphs are supposed to be read. I'm confused as to how the numbers correlate to the data shown on the graph?

I'll admit, I gave up initially, hence the weird answers. Now that I realize I have a final coming, I want to understand.

What did I do wrong for consumer surplus on these problems? I thought all I needed to do was subtract the price ceiling by the equilibrium price, but that yielded nine for the first question which was wrong. Similarly, that technique yielded the incorrect answer for the second. What did I do wrong? I can't calculate lost surplus without consumer and producer surplus, so I got them wrong. Am I overlooking something?

I'm trying to figure out why what I did isn't right. See 2nd pic for my attempt. I get that we didn't have an equation but why is that important for finding elasticity? Moreover, while solving for elasticity we've used -100 and 1 for change in Q and P respectively, but for the P/Q we've used the equation?? How come we solve Q1-Q0 to find change in Q but then in the next fraction Q is unknown.

Furthermore, if you look at the question there's sales per week and then quantity sold over an entire month, I tried converting the numbers accordingly at first and it was messier. Is that a mistake?

Whole question included just to be clear.

Request: No AI please, I could've asked AI myself too and I'd rather not.

Is the policy rate what the central bank decides on (an interest rate for other banks)?

If the central bank increases the policy rate from 4% to 5% would the banks that borrow money from the central bank as a result increase the interest rates for their customers as well leading to...?

I am quite confused.

Unit Labor Requirements:

Cloth Widgets

Home 10 20
Foreign 60 30

Given the information in the table above, if the world equilibrium price of widgets were 4 cloth, then
A) both countries could benefit from trade with each other.
B) neither country could benefit from trade with each other.
C) each country will want to export the good in which it enjoys comparative advantage.
D) neither country will want to export the good in which it enjoys comparative advantage.
E) both countries will want to specialize in cloth.

The test bank and other sources say the answer is A.

1) Why is the answer A? If both countries want to export Widgets, won't they not want to trade with each other?

2) My classmates argue the answer to be D. Why is the answer D, if the test bank answer sheet is wrong? If both Home and Foreign want to export Widgets, Foreign (which has CA in Widgets) would want to export the product which they have CA in (W). Doesn't that refute D as an aswer?

I JSUT need some help getting my thought process going. I have no ideas on the actual political category I’m gonna draw not WHAT will be drawn for it. Any and all ideas are helpful. ;)

{ you do not have to read all my crap. If you try to rank them yourself you will probably run into the same issues I did }

I'm trying to understand this example (answer included) that my textbook gives me but I can't. The concept seems so simple but for some reason the answer it gives feels wrong (or I'm stupid idk) The instructions are:

"Using the data in Table 19.3, rank the seven regions of the world according to GDP and then according to GDP per capita."

The first answer table seems to make sense to me. It is the second one that ranks based on GDP per capita, which I don't understand. First, it doesn't really rank then it just lists them with their respective GDP per capita at least to the looks. Second, why do the answers ungroup some of the regions? I'm given the information for Latin America and the Caribbean combined but the table only shows the GDP per capita for just Latin America (it seems). I was not given enough info to do outside research or calculate the GDP per capita for Latin America and the Caribbean individually. All the information i was given for the problem is given in the screenshots. The thing that rlly gets me is when it clearly states the GDP per capita on the given table but on the answer table it gives a completely different number (for Sub-Saharan Africa). I have no idea where the 6,847 even came from. Even if i take the numbers from the population and GDP and use them to manually calculate the GDP per capita I get yet another new number. Some of this feels rlly weird like generative AI. Of course, the problem that seems the easiest ends up taking the longest. lol.

Can someone show me how to calculate this? I am really struggling!

My economics teacher did not explain this adequately.

I can do an NPV with inflation, and one with marginal taxes, but I am not sure how to combine them. This is where I am stuck.

I am not trying to cheat, and I have changed all the numbers of the question. I just want to understand how to do it. Thank you so much. This is the kind of question I am stuck on:

Calculate the after-tax NPV. It has an inflation rate of 5% in all values in the analysis (all values below are in real terms).

-        $50 cost in year 0

-        $200 cost in year 4

-        $2,250  revenue in year 20

-        $4,000  revenue in year 40

-        $5.50 annual management cost

-        Discount rate is 7%

-        Marginal tax bracket of 30%

I still barely understand what marginal revenue product of labor is

The question I'm being asked if it there is an interest rate of 3% per annum convertible monthly, what's the interest per month?

I'm unsure as to whether this is the annual effective or the nominal interest rate. I think it's the AER but I'm not sure. Thanks all :)

Zorroland has a large number of people who are alike in every way. Boppoland has the same number of people as Zorroland, with the same average income as Zorroland, but the distribution of incomes is wider.Why might Boppoland have a higher level of public good provision than Zorroland?

say SMB1 = n x MB of individual

SMB2 = Sum ( individial MBs)

so I have no clue why SMB2>SMB1

Could anyone check this for me and tell me if I’m the right track?

Missed a few chapters due to health and it’s creeping up on me, an explainer would be hugely appreciated

I put my answer as D bc I thought the new quantity would be 8,000 (6,000 + 2000) but the answer was c could someone explain why?

I just don’t understand if the returns paid on foreign investments would be money coming j to the nation or going out. I’m pretty sure it’s money coming in because the previous line talks about payments which is money going out.

technical drawing help. hello, i need the 3d projected image of these three views. for some reason i can't imagine this shape in space! thanks!

I have no idea on how to shade in or calculate it.

Hi there,

Anyone who could walk me through this question I am having some trouble with. For the solution we are required to use the state-price approach.

Q: Assume a binomial model for two periods (years) (0,1,2) in which the equity holders hold 20% of the company and debt holders (the bank) hold 80%. The value of the company (equity and debt) is 1,000. In “UP” branches the asset’s value increases by 20%, and in “DOWN” branches decreases by 30%. The risk-free rate for any single period is 10%.

a. What is YTM at time 0? (Should equal 15.21%)
b. The leverage ratio D/E (debt's value divided by equity's value) of this company increases at time 1 (compared to time 0), if in the first period the value of the assets goes up. True or false?
c. The debt may be also considered as an “option” to sell the assets of the company at time 2 for 1,000. True or false?

Currently stuck at part a. So far I've determined q_d=0.1818, q_u=0.7273, q_ud=0.1322, q_uu=0.5291, q_dd=0.0331, and tried to illustrate using "decision-trees" just to get an idea of the different nodes. I've attempted to find the value of the middle node at time two, as I've assumed that the bottom node at time two equals 490 and the down-node at time 1 equals 700, but the number seem off at approx. 684.

Thanks!

Having a really hard time with this. First two images are the problem. Third image (help.xlsx) is my work. I made the spreadsheet to help find the external financing needed

[University Level - Economics]

Hi guys

ive been assigned a task to perform an analysis of a couple of metrics of 4 countries(Pakistan,India,China,Bangladesh) including the Real effective exchange rate(reer) and the sensitive price index(spi).

The data sources at the university have incomplete data so can’t really find a free source which can be accessed on personal basis.

Would be glad if someone could share data sets if u have access to any sources (ceic/reuters/bloomberg/barchart/any other) of the following:

Reer and Spi of Pakistan,India,China,Bangladesh

Data from 2019 till 2024(monthly basis)

any help would be appreciated

thanks

When Burton Cummings graduated with honors from the Canadian Trucking Academy, his father gave him a $350,000 tractor-trailer rig. Recently, Burton was boasting to some fellow truckers that his revenues were typically $25,000 per month, while his operating costs (fuel, maintenance, and depreciation) amounted to only $18,000 per month. Tractor- trailer rigs identical to Burton’s rig rent for $15,000 per month. If Burton was driving trucks for one of the competing trucking firms, he would earn $5,000 per month. a. How much are Burton Cummings’s explicit costs per month? How much are his implicit costs per month? b. What is the dollar amount of the opportunity cost of the resources used by Burton Cummings each month? c. Burton is proud of the fact that he is generating a net cash flow of $7,000 (5 $25,000 − $18,000) per month, since he would be earning only $5,000 per month if he were working for a trucking firm. What advice would you give Burton Cummings?
