The Goldman Fund has hired you to summarize the effects of climate change on plant and animal species found in California. In your summary, please highlight what changes you might expect to see under global warming for different types of species and communities in California. You are not expected to speak to specific species, instead think of broad categories (e.g nectar feeders or primary producers). Be sure to identify what ecological principles lead you to each of your hypotheses and what experimental evidence suggests the principle is true.

Read through the material provided on how the Federal Reserve responded to the subprime mortgage crisis and consequent 2008-09 recession with monetary policy. Now, answer this: Do you support what the FED did in theory and practice? In particular, discuss your take on the series of quantitative easing measures we have witnessed since the crisis and the recent changes in FED outlook. Do you believe it is too early to raise interest rates by tightening money supply, or do you think this is the perfect time?

A square single loop of wire 4.00 cm on a side with 875 turns lies in the xy-plane. The loop is in a uniform magnetic field that changes at a steady rate from B⃗ =(0.200T)i^+(0.150T)k^B→=(0.200T)i^+(0.150T)k^ at t = 0 to B⃗ =(0.300T)i^+(−0.200T)k^ B→=(0.300T)i^+(−0.200T)k^ at t=3.00s. At the time t=2.00s,

b) Find the direction of the induced current in the coil as seen from a point on the +z-axis.

Many investors believe that the stock market’s directional change in January signals the market’s direction for the remainder of the year. This so-called “January Indicator” is frequently cited in the popular press. But is this indicator valid? The accompanying table summarized the relevant changes in the Dow Jones Industrial Average for the period December 31st, 1927 to January 31st, 1981. Based on your analysis, do the data appear to confirm the validity of the January indicator?

Portfolio Alpha contains a 5-year zero-coupon bond with a face value of $5,000 and a 9-year zero-coupon bond with a face value of $6,050. Portfolio Beta is composed of only a 7-year zero-coupon bond with a face value of $10,000. The current yield on all three bonds is 5% per annum. Show that both portfolios have the same duration. What percentage changes in the two portfolio values would result from all three yields jumping to 7.5% per annum?

Suppose the federal government unexpectedly decreases its spending.
Using the IS-LM model, explain how this contractionary fiscal policy affects the real interest rate, r, and total output, Y , in both the short run and the long run.
What happens to consumption, C, investment, I, and government expenditure, G, in the short-run?
What happens to C, I, G, and r in the long- run?
(Note: For full credit, you must provide a brief explanation for why each variable changes or remains constant.)
