A 1-year long forward contract on a non-dividend-paying stock is entered into when the stock price is $40 and the risk-free rate of interest is 10% per annum with continuous compounding. (a) What are the forward price and the initial value of the forward contract? (b) Six months later, the price of the stock is $45 and the risk-free interest rate is still 10%. What are the forward price and the value of the forward contract? Solution: a) = 44.21 b) = 47.31 = 45 - = 2.946 5.15. The spot price of silver is $15 per ounce. The storage costs are $0.24 per ounce per year payable quarterly in advance. Assuming that interest rates are 10% per annum for all maturities, calculate the futures price of silver for delivery in 9 months. First we need to calculate the present value of the storage cost that has to be consider as part of the . In this sence the storage cost implies 0.06 per 3 month 0.06, so the PV of the cost of storage for 9 month is: Now we continue calculating the price of the future including the cost of storage: 5.26. The spot price of oil is $80 per barrel and the cost of storing a barrel of oil for one year is $3, payable at the end of the year. The risk-free interest rate is 5% per annum continuously...

It caused social class distinction in China, and caused negative social and economic effects in Spain. First, Document 1, 3, 5 and 7 should be grouped together because they were all written by Chinese during the Ming dynasty. Document 1 was written by country official Ye Chunji. It was a order issued to limit wedding expenses. Upper class people wanted to spend more and more silver on wedding, while one bar of silver was enough for lower class people on wedding. The author noticed the social class distinction in the country, so he issued this order, trying to used his power to regulate the spending on wedding. He thought greedy people would waste silver, so wedding expenses need to be limited. Document 3 was written by Wang Xijue. He reported the reason of why grain was cheap to the emperor. Despite the poor harvests, the government required silver taxes but they paid little to people. The lacking of silver being given to the farm workers caused less production of grain and it also harmed the rights of underclassmen. The court official reported this because this was hurting the Chinese economy, which meant less money for him. Also, he needed the support for his home district, so he reported to the emperor and...

    ...Core 1 Linear Graphs and Equations For any straight line, the gradient (M) is: dy/dx or difference in y/difference in x which is (y2-y1)/(x2-x1) Equation of a line: y=mx+c which is used when the gradient and intercept is known or y-y1=m(x-x1) when the gradient and the co-ordinates (x1,y1) of a single point that the line passes through is known. You'll need to learn this equation. [The equation of the line can be kept in this form unless stated in the exam. (reduces error chance) Also, usually there is a working mark, so state the fact that the gradient is difference in y/difference in x] The mid-point of two graphs is found by (x1+x2)/2 , (y1+y2)/2 in the form (x,y) Lines with the same gradient are parallel, while lines with gradients that are negative reciprocals of each other is perpendicular to it. (perpendicular means at a right angle to) [they usually want you to state that 'the perpendicular line's gradient is the negative reciprocal', so stick it in. It is also usefull to draw out diagrams if they ask about right angle triangles, (usually something to do with negative reciprocals rather than pythagoras.)] In 2D Lines that are not parallel must intesect, the point of intersection can be found by simultaneous equations by: • equating coefficients of the two lines • substituing one equationinto the other • equating both equations for y. Surds surd form is exact. they involve irrational roots, which are roots that cannot be...
