Even though they're separated, Paul and Camille decide to study a price-fixing agreement that will mutually benefit them. The idea is that they both agree to a price higher than the Bertrand equilibrium price, using the Grim Trigger strategy (if they detect a deviation from the agreed-upon price, they switch to playing the static Bertrand prices forever). What is the weakest assumption on the discount factor & e (0, 1) that supports the existence of a SPNE with collusion in this market (that is, a SPNE with a price strictly higher than the Bertrand equilibrium price from the previous question)?

Compounding: the accumulation of a sum of money when the interest earned on the sum earns additional interest. Because of compounding, small differences in interest rates lead to big differences over time. Assume that instead of spending $30,000 on your wedding, you only spend $5,000. You use the remaining $25,000 to buy stocks/bonds and you hold them for 40 years. Calculate the Future Value on $25,000: If your portfolio's rate of return is 8% (i = 0.08), Future Value = If your portfolio's rate of return is 6% (i = 0.06), Future Value = In a 200-word paragraph, please summarize the results of your calculations and list three things that you learned from this exercise.
Sabrine purchased 4,500 shares of a mutual fund at an offer price of $8.88 per share. Later, she sold the investment for $7.38 per share. During the time she owned the shares, the fund paid a dividend of $0.52 per share. What was her return on her investment? (Round to the nearest tenth.)
The COVID-19 pandemic has caused an unprecedented increase in savings in many countries around the world. In the EU, the savings rate of households has jumped from 12.5% to 17%. In 2008-2009, it had moved from 12.5% to 14% (Dossche and Zlatanos 2020). Even if the source of 2020 surge in savings is different from the one of 2008, it is obvious that this increase does not result in more investment and growth. QUESTION: 1.

Dana was dating Wade, a wealthy real estate entrepreneur. Wade was much older than Dana and knew he needed to offer something “special” to make her stay. Wade told Dana that if she continued dating him, he would pay her $10,000 a month. Wade paid Dana for two years when suddenly, for no apparent reason, he stopped the monthly payments. Dana stayed with Wade for another six months, but decided enough was enough and left. She wanted the $60,000 she was owed for the six months; Wade refused to pay her. Is Dana entitled to the $60,000?

A sales position is offered at a pharmaceutical company with two salary options. Option A would pay an annual base salary of $15,000 plus a commission of 7% on sales. Option B would pay an annual base salary of $30,000 plus a commission of 6% on sales. The equation y 15,000+0.07x models salary Option A and the equation y 30,000+0.06x models salary Option B, where x represents the amount of annual sales and y represents the annual salary in both equations. Determine the annual sales required for the options to result in the same annual salary. The annual sales required would be $ (Type an integer or a decimal)
COVID-19 brought global economic and financial ramifications that were felt through global supply chains, from raw materials to finished products. Some term it as a black swan event that may finally force many companies, and entire industries, to rethink and transform their global supply chain model. If you are the CEO of a U.S. based company which is heavily dependent on foreign locations for sourcing and manufacturing, how would you make short-term and long-term plans to modify your supply chain model? List and discuss the main considerations or factors that will influence your decision.
The Salar de Uyuni basin in Bolivia contains one of the world's largest deposits of lithium. However, this basin can also be used to grow quinoa, one of the region's most important crops, and is the site of considerable tourism. A study estimated the value of mining lithium from this basin to be worth $380 million, quinoa farming to be worth $11 million, and tourism to be worth $27 million. Assume that if the basin is mined that it cannot be used for farming or tourism. The opportunity cost of mining the basin is _____, and (based on these numbers) Bolivia _____ mine for lithium here. -$11 million; should -$38 million; should -$27 million; should -$418 million; should not
