1. The United States began including a chicken pox vaccine as part of its standard panel of childhood vaccines in 1995, and shortly after introduced a shingles vaccine for those over the age of 60. In countries that did not vaccinate against chicken pox (today, relatively few), the shingles vaccine was not necessary. Explain why this is the case. Be sure to use terms on the immune system in your response (e.g. secondary immune response, memory cells).

The relative donor effect of simple ligands can be determined by measuring the carbonyl stretching frequencies of their metal carbonyl coordination complexes. Imagine you have prepared a series of L2-Ir(CO)Cl complexes and measured the carbonyl stretches. Assign the stretches (2102, 2054, 2032, 2014, 1995 cm -1 ) to the complexes containing the following ligands (assume that all ligands are purely σ-donors): NPh3, PPh3, pyridine, 4-fluoropyridine, 4-bromopyridine. Explain your reasoning!

According to the Internal Revenue Service (IRS), the chances of your tax return being audited are about 6 in 1,000 if your income is less than $50,000; 10 in 1,000 if your income is between $50,000 and $99,999; and 49 in 1,000 if your income is $100,000 or more (Statistical Abstract of the United States: 1995).

If two taxpayers with incomes under $50,000 are randomly selected and two with incomes more than $100,000 are randomly selected, what is the probability that none of these taxpayers will be audited by the IRS?

a) In 1994, one subsidiary of Daimler-Benz, Daimler-Benz Aerospace, had an order book of DM20 billion, of which 80% was fixed in US dollars. In 1995, Daimler-Benz reported losses of DM1.56 billion, the largest in the company’s 109-year history. Briefly explain why Daimler-Benz failed to hedge its position [Hint: In your answer, you should refer to the primary goal of risk management as stated by Stulz (1996, Journal of Applied Corporate Finance)].

Netscape planned to offer 3.5 mln shares at $14 in an IPO. A day before the offering their underwriters suggested to change the offer to 5 mln shares at $28. Netscape had an IPO on August 8^th, 1995 -- 5 mln shares at $28 were offered (excluding the 15% overallotment). During the first day of trading, the price of the stock rose to a maximum of $73 and closed the day at $54. How much money did Netscape ‘leave on the table’? For simplicity, disregard the overallotment shares and the underwriter’s spread.

6. In the most recent recession, the earnings of college- educated workers declined. This caused many policy makers and those in the press to claim that college was no longer worth it for students. Does this conclusion necessarily follow from the observed changes in college-educated workers’ earnings?
