Question: Help me out on IS curve: For the IS Curve (S-I)=(G-T)+(X-M), How come saving minus investments will be equal to fiscal balance and trade balance? i dont understand the logic how it is directly proportional?

Answer: The IS and LM model formula, S — I = (G — T) + (X — M). tels you that the aggregate savings – aggregate investment should equal to (government expenditure – Taxes) + ( Total export – Total import). The whole effect should be balanced.

Answer: Diseconomies of scale lead the marginal cost of a product to increase as a company grows. So you can not reach the answer here only by comapring with increase in output only. here you need to compare with previous output increase with previous average cost increase.

Question: Portfolio standard deviation for 5 assets: Guys, CFA Institute pretty clear talks about 2 and 3 assets in the portfolio, but what shall I do if I need to calculate standard deviation of a portfolio with 5 assets? Which formula should I use? Thanks in advance.

Answer:No specific formula is given for that. So. I think you should use same formula in extended form for the calculation of 5 assets.

Question: Shares Repurchase: Could anyone give a brief explanation on why a share repurchase is considered a way of paying dividends to shareholders? And why is usually considered a better action than paying dividends with cash? Thanks!

Answer: Usually those companies who are not paying dividends regularly use this approach. Hence through repurchase company pays a cash and buy back the part of shares outstanding, Though the shareholders who sold their shares bene?ted with cash baclt( dlvldend la also a form of paying cash to shareholders). And the Tax on dividends is paid by company. not by shareholders
