Suppose the US is in the midst of a mild recession. Which of the following is a valid economic argument as to why government stimulus might be unnecessary. Stimulus funded by deficit spending can crowd out private borrowing of loanable funds. If the recession is mild, then the market may correct itself, without harming investment. It's impossible for fiscal stimulus to increase aggregate output. We don't need stimulus when the Federal Reserve will always enact the correct monetary policy to resolve a recession. The spending multiplier from an increase in government spending is always more effective than from an increase in C, I, or NX.

PROBLEM 3: Integration by path parametrization Given $g(z) = \frac{6(z+4)}{z^2 - 4}$ (1). and circular contour shown below. (A) Write x, y and z in term of $\theta$ and show that: $z = 2 \cos \theta + i2 \sin \theta = 2e^{i\theta}$ and $dz = (-2 \sin \theta + i2 \cos \theta)d\theta = i2e^{i\theta}d\theta$ (B) Write g(z) as a fraction containing $\theta$ as the only variable. (C) Multiply result you got in (B) by $\frac{e^{-i2\theta} - 1}{e^{-i2\theta} - 1}$ and get g(z) in a complex function of $\theta$ form $g(z) = \frac{a \text{ complex function of } \theta}{a \text{ real function of } \theta} = h(\theta)$ (D) $\oint_C g(z)dz = \int_0^{2\pi} h(\theta)d\theta$. Evaluate this integral. Show all steps. HINT: use result found in B and C and $1 - \cos 2\theta = 2 \sin^2 \theta$ Answer: Real Part = [ ]$\pi$ Imaginary Part = [ ]$\pi$

3. Let X be the daily salary of one company and let Y be the daily salary of one of its competitors.Let X~Nx,1.44and Y~ Nu,1.50Suppose that a recruiting agency suspects that there is a significant difference between the mean daily salaries of the companies.They collect a random sample of n=50 employees from the first and m=40 employees from the second,resulting in the sample means =$160 and y=$155 per day respectively a.Clearly state the hypotheses. b.

21) The following plot shows data from a two-substrate enzyme mechanism. S1 + S2 <==> P1 + P2 Enzyme 1/v (µM?¹min) 4 3 2 5 -0.4 -0.2 0 0.2 0.4 1/[S1] (µM?¹) Which of the data sets a or b was recorded at the highest concentration of the second substrate (S2)? (Explain for 1 pt) Is this a double-displacement (ping pong) or ternary complex mechanism? (Explain for 1 pt) The plot to the right shows the same enzyme reacting with the second substrate concentration held constant in the presence and absence of the product P2. What type of inhibition pattern is observed? (1 pt) Does this inhibition pattern support the double displacement, random-order ternary complex, or sequential order ternary complex mechanism? (Explain for 1 pt) 2.0 1.5 1.0 0.5 -0.4 -0.2 0 0.2 0.4 0.6 1/[S1] (µM?¹)

A risk manager needs to break down the more complex callable/puttable structures into simpler components to hedge the products. She is handed a 10-year no-put 1-year Bermudan puttable swap where she receives a fixed rate of 3.50% and pays 6-month LIBOR, both semi-annually for 10 years. After 1 year, she can decide if she wants to continue doing that for the remaining term or end the entire contract at that time. If she does not end the contract there, she can do so every 6 months until the final period. (a) Use the following market instruments to re-engineer the structure (no need to use all of them), indicate clearly which sides she needs to do (long/short, payer/receiver swaption, pay/receive fixed on swap): - 1-year swap - 5-year swap - 10-year swap - 1-into-9 European swaption - 1-into-10 European swaption - 1-into-9 Bermudan swaption - 1-into-10 Bermudan swaption (b) Can a Bermudan swaption be replicated by a series of European swaptions? Why or why not? Please explain briefly.
