...ECON 2113 Homework 2 L4 Hu Weiwei 20268464 Xu Lili L4 Hu Weiwei 20268464 Xu Lili 1a. The demand curve is estimated as Qd = 1600-2400P and the supply curve for pay telephone service is Qs = 200+3200P. When equilibrium is reached, the quantity demanded is equal to the quantity supplied. Thus, we can solve 1600-2400P = 200+3200P to find out the equilibrium price. By calculation, the equilibrium price P = $0.25. Substitute P = $0.25 into the demand curve equation, Q = 1600-2400(0.25), the equilibrium quantity Q = 1000. Therefore, the equilibrium price is $0.25 and the equilibrium quantity is 1000 pay telephone calls per month. 1b. With the effective price ceiling at $0.10 on local pay phone service in long run, it is below the equilibrium. Since the quantity demanded is larger than the quantity supplied after the price ceiling is imposed, shortage is resulted. As the price is restricted at $0.1, though Qd = 1600-2400(0.1) = 1360, Qs = 200+3200(0.1) = 520 < Qd = 1360. The quantity supplied is not enough to satisfy the quantity demanded. It results in a shortage of 1360-520 = 840 pay telephone calls per month.Therefore, the maximum quantity...

...Unit 4: Project Keys Fan Piano University HU 300 – Art and Humanities August 4, 1999 Happiness and liberty were clearly a motivating force during the fight against desegregation in the 1950s. The student leaders in African American community began to take the stage under the spotlight by emerging with immense power and energy. Barbara Rose Johns possessed an important quality to being a successful leader and that quality, understands leadership is a communal effort not singular. Barbara displays this understanding when she led the student strike at Robert R. Morton High School in Farmville, Virginia. At only 16 she stood before the faculty and student body in a staged assembly and demanded the teachers leave the auditorium as she wanted to address students only. Leading the strike against her school was out of character for Barbara, who is described as “quiet and studious,” she was inspired by the likes of notable African American leader Booker T. Washington and Richard Wright, and she read books written by both men. The students who lead the strike at Morton High School had to embrace the racism that kept their school in horrible conditions, as they embraced the challenge to change the conditions; they also embraced rebellion, adversity, and independence. Brown v. Board of Education of Topeka was the most influential case in history of the National Association for the Advancement of Colored People (NAACP) that led to the end of segregated schools and the strike at...

...Teaching the Costs of Uncoordinated ; Supply Chains Charles L. Munson • Jianli Hu College of Business and Economics, Washington State University, PO Box 644736, Pullman, Washington 99164-4736 munson@'ivsu.edu • hu@mail.wsu.edu , Meir J. Rosenblatt (deceased) formerly Professor at Washington University in St. Louis, Missouri, and Technion—Israel Institute of Technology This paper was refereed. Supply-chain management has become a prominent area for teaching and research. Academics and managers realize that communication and coordination among members of a supply chain enhance its effectiveness, creating financial benefits to be shared by the members. We have collected numerical examples covering (1) location decisions, (2) centralized warehousing, (3) lot sizing with deterministic demand, (4) demand forecasting, (5) pricing, and (6) lot sizing with stochastic demand in a newsvendor environment. The examples are suitable for classroom use, and they illuminate the rewards supply-chain members can obtain by eliminating naturally occurring supply-chain inefficiencies and the costs of not doing so. {Professional: OR/MS education. Supply-chain management.) hen each member of a group tries to maximize his or her own benefit without regard to the impact on other members of the group, the overall effectiveness of the group may suffer. Such inefficiencies often creep in when rational members of supply chains optimize individually instead of coordinating their efforts. Nowadays...

I will first begin by locating a piece of architecture that catches my attention then provide a brief detailed explanation of what I see. I will then explain the element of form and function as it relates to the architectural work. Meanwhile I will locate a piece of art work that I find engaging and start by describing the work using terminology from the text. The following question will also be addressed. What is the medium? When was the work made? Is this work abstract or representational? What is the purpose of this art work? And what does it mean to me? For my selection of architecture I have chosen the Burj Al Arab Hotel.

Smith W e present a framework and empirical estimates that quantify the economic impact of increased product variety made available through electronic markets. While efficiency gains from increased competition significantly enhance consumer surplus, for instance, by leading to lower average selling prices, our present research shows that increased product variety made available through electronic markets can be a significantly larger source of consumer surplus gains. One reason for increased product variety on the Internet is the ability of online retailers to catalog, recommend, and provide a large number of products for sale. For example, the number of book titles available at Amazon.com is more than 23 times larger than the number of books on the shelves of a typical Barnes & Noble superstore, and 57 times greater than the number of books stocked in a typical large independent bookstore. Our analysis indicates that the increased product variety of online bookstores enhanced...

...Linear Programming (LP) Linear programming, simply put, is the most widely used mathematical programming technique. It has a long history dating back to the 1930s. The Russian mathematical economist Leonid Kantorovich published an important article about linear programming in 1939. George Stigler published his famous diet problem in 1945 (“The Cost of Subsistence”). Of course, no one could actually solve these problems until George Dantzig developed the simplex method, which was published in 1951. Within a few years, a variety of American businesses recognized that they could save millions of dollars a year using linear programming models. And in the 1950s, that was a lot of money. In his book Methods of Mathematical Economics (Springer-Verlag, 1980), Joel Franklin talks about some of the uses of linear programming (LP). In fact, about half of his book is devoted to LP and its extensions. Today, we will analyze one of the examples provided in that book. The example comes from a 1972 article published in the Monthly Review of the Federal Reserve Bank of Richmond. Alfred Broaddus, the author, was trying to explain to bankers how Bankers Trust Company used linear programming models in investment management. His example was simple and effective. The bank has up to 100 million dollars to invest, a portion of which can go into loans (L), and a portion of which can go into securities (S). Loans earn 10%, securities 5%. The bank is required to keep 25% of its invested...

...Kaamashri Latcha Every year, the United States studies and presents reports on hu- man rights practices in more than 190 countries around the world. In the 2010 Human Rights report, China was chastised by the U.S. for its poor human rights record. The Chinese government has been accused of imprisoning citizens for practicing their religious faith and op- pressing freedom of expression and information. The one child per family policy has been attacked continuously by the U.S. and they have also con- demned the arrest, detention and disappearance of Chinese citizens. This latest human rights report issued by the U.S. has highlighted many human rights transgressions in China. Yet the U.S. criticism on China’s human rights has been contradicted by China. As the fastest developing economy in the world, China is intent on defending its position where human rights are concerned. The two countries have had dialogues on human rights issues, the latest being held on April 27-28, 2011 in Beijing. The discourse came after prolonged foot- dragging on the part of both nations; talks were suspended for a few years. Both countries have not been able to publicly accept their human rights errors, but each has been focusing on violations committed by the other. Against the backdrop of military buildup by both countries, the con- troversy over whether the U.S. is morally justified in criticizing China’s hu- man rights can have far reaching and devastating effects for the entire world. The two...

Kelly Jr and Joan Sabate* Department of Nutrition, School of Public Health, Loma Linda University, Loma Linda, CA 92350, USA The epidemiological evidence for the cardio-protective effect of nut consumption is presented and reviewed. Four large prospective epidemiological studies of primary prevention of coronary heart disease are reviewed and discussed (Adventist Health Study, Iowa Women’s Health Study, Nurses’ Health Study and the Physicians’ Health Study). Other studies of nuts and coronary heart disease risk are addressed. The combined evidence for a cardio-protective effect from nut consumption is summarized and presented graphically. The risk of coronary heart disease is 37 % lower for those consuming nuts more than four times per week compared to those who never or seldom consume nuts, with an average reduction of 8·3 % for each weekly serving of nuts. The evidence for a causal relationship between nut consumption and reduced risk of coronary heart disease is outlined using Hill’s criteria for causality and is found to support a causal cardio-protective relationship. Nuts: Cardiovascular: Coronary heart disease: Diabetes: Cohort studies: Causality: Hill’s criteria Nuts have constituted a part of mankind’s diet since pre-agricultural times (Eaton & Konner, 1985), providing a complex food...
