A company must make payments of $10 annually in the form of a 10- year annuity- immediate. It plans to buy two zero coupon bonds to fund these payments. The first bond matures in 2 years and the second bond matures in 9 years, and both are purchased to yield 10% effective. What face amount of each bond should the company buy in order to be immunized from small changes in the interest rate (redington immunization)?

To keep either weak or strong sustainability, we can do something. Given the two cases, 1) a carbon tax imposed on primary production (supply side, firms) and 2) a carbon tax imposed on end-users (demand side, consumers),

• What kind of benefits that we can expect from each case?
• For instance, what would be the behavioral changes in producers and consumers?
• Which one is more cost-efficient?

As marginal utility decreases, total utility

On January 9, 2015, President Obama announced a proposal to make community college free for all students. What would be the benefit to the economy as a whole resulting from this change? Of the four factors of production (land, labor, capital, and entrepreneurship), which factor would be enhanced by such a program? What would happen to the supply of college-educated labor? Would the demand for college-educated workers change? If so, what changes might occur?
