Econ ON OLIGOPOLY & SOME GAME THEORY IDEAS WITH OLIGOPOLY - Assignment Example In the contestable market the evaluation of dealings among current firms and prospective entrants is investigated more critically. The market incumbents maintain an oligopoly through the determination of price levels in the market in their favor. Again the oligopoly is maintained by the government favor and creates a barrier for other firms from venturing in the market. 2) Suppose there are two firms operating in an oligopoly (termed a â€Å"duopoly†), where the firm 1 cost function is given by C1 = 18Q1, for C1 = total cost, and Q1 = firm 1 output. The cost function for firm 2 is given by C2 = 21Q2, and C2 = total cost of firm 2, and Q2 = output of firm 2. The inverse demand for the product, Q, being sold by the oligopolist firms is given by P = 127 – 3Q, where Q = Q1+ Q2, and Q1 and Q2 are the same product (vats of toxic solution for breaking down chemical components to be used in downstream plastic manufacture). Taking into the consideration the Cournot model in regard to the duopoly that is two firms where both firms concurrently decide a quantity to produce. Designating the quantity q1 as the amount produced by firm 1 and q2 as the corresponding amount produced by firm 2. Therefore the total quantity The firm production choices are strategic substitutes. That is, an increase in the amount produced by firm1 (holding fixed the underlying amount produced by the corresponding firm 2) will considerably lower the market price and thus resulting in lesser profits for firm 2. Thus, every firm ought to take into consideration the prevailing the production decisions of the other supplementary firm in the process of undertaking its individual production decision Firm 1 possess a marginal cost of production equivalent to c1 accompanied by firm 2 which possess a marginal cost of production equivalent to c2. The corresponding Nash equilibrium is computed through the employment tow

Metropolitan Opera House Essay Example for Free

Metropolitan Opera House Essay Maria Callas gives an outstanding performance at the Metropolitan Opera House in New York. This is unsurprising as Callas was one of the most famous sopranos of her time and a recognised Diva. The Newspaper review is gushing in praise of Callas who gives a powerful and convincing performance. It is noted that the reviewer had some reservations on a previous performance but the performance of Violetta in La Traviata left the reviewer in no doubt that Callas gave a performance that was the best interpretation he had ever witnessed in all his time attending and reviewing operas. The performance as Viloletta is a more congenial part than previously seen by the reviewer and it has so much passion and personal interpretation that it is difficult to distinguish between the dramatic and vocal performances. The whole performance seems real and the acting and singing become one, the perfect operatic qualities. The words in an opera can seem disjointed and difficult to express when read without music and it is Callas who brings the script and plot alive by sewing all the parts together to make an outstanding dramatic performance in conjunction with the musical performance by the orchestra.. She still had the slight wobble in her voice which is evident on the CD in some places, for example at 1:19 and 02:00 when the singing becomes fortissimo. However her reputation as a performer was so great that her fans and the reviewer where able to forgive this perceived fault and even claim that it added to the intensity of her performance. It shows emotion in the voice and this adds to the tragic quality of the roles often played by female opera singers. The CD shows a wide range of singing from the initial pianissimo start and the pizzicato accompaniment from the string section building up to 1:13 when Callas builds to an ornament at 1:19. The whole performance is very smooth and displays and you can hear the passion in Callas’ voice when she expresses her feelings. The reviewer mentions her striking presence which is an important part of opera throughout the world. Callas’ presence was reinforced by her status as a Diva and her reputation was worldwide. She had performed for the previous 7 years at La Scala in Milan to triumphant reviews and had gained publicity 4 years earlier when her appearance changed dramatically having lost 30 kilos in weight. She was married to a prominent businessman and Opera lover and was on the verge of starting a relationship with a world famous shipping magnate. Callas was portrayed as a Diva in much the same way as someone like Madonna is today and the public interest in her life only served to fuel her presence and reputation on the stage. Opera is performance on a grand scale so much so that opera venues are some of the grandest, most iconic and well recognised places in the world, for example the Sydney Opera House. Those who succeed in such an environment must be larger than life personalities. Maria Callas was certainly a Diva and her life was followed and reported by fans and the press alike. Her life was lived in the glare of publicity and even though she led a private life following her retirement in 1965 she still attracted great interest when she made public appearances. It is easy to see the appeal of her character and that many people liked to think of her as a tragic heroine due to difficult events in her life. In many ways this mirrored the Operatic roles she played with so much conviction it sometimes blurred the boundaries between reality and performance.

Women in Politics Essay -- Papers

Women in Politics Beginning with the early nineteen hundreds, women from all over the country have bounded together, forming leagues and clubs for equal rights. However, it wasn't until today "at the dawn of the twenty-first century, states and international community can no longer refute the fact that humanity is made up of two sexes, not just one" (Oliveria 26). Why has the woman's move for equality just now started to balance itself out? Well, the answer is quite simple; women are just now being looked at as semi-equals. They are beginning to become corporate executives in businesses, and popular in the field of medicine and law. Women have tried hard to push themselves forward in society to create a balanced and harmonious economy and so far it has been successful. Barriers of all kinds have been broken, well, all except a few, mainly in politics and with the information I have collected I will show why. Politics†¦when one stops and thinks of the word "politics" what naturally comes to mind? Our founding fathers, Presidents George Washington, John Adams and Thomas Jefferson; the popular political figures of today, President Bill Clinton, George W. Bush and Al Gore; or do we think about Belva Ann Lockwood, Jeannette Rankin, Frances Perkins, and Eugenie Moore - who? When American's think about politics, Lyn Kathlene, journalist for the "Higher Education Chronicles," states that "ninety-five percent of the time they envision a man who is in charge of running, or helping to run, their country." Is society to blame for this misconception that women do not hold important roles in government and participate in making important decisions for our country? Not really, people just don't hear or read about women in politics as often as... ...ernment? No, but society needs to realize that this is "'the dawn of a new century'" and the role of the female should indeed be reevaluated. Bibliography: Arenofsky, Janice. "Women in Politics."

Aerophones: Musical Instrument and Small Circular Pieces Essay

The pi is believed to be truly a Thai instrument used since the ancient times. The sound it produces and the blowing technique is unique to the country of Thailand. The basic material for this instrument is hardwood or marble. Its reed comes from small circular pieces of the palmyra leaves tied to a small tube made of silver, bronze, or brass. It is usually played with percussion instruments. Khaen is the most important folk instrument in north Thailand and in Laos. It is made up of fourteen long thin bamboo tubes that are four feet long. The range of the khaen covers two octaves of seven pitches. It is described to produce a drone that is often described as mournful and plaintive. Membranophones The taphon instrument is somewhat similar to the siphon of India. Instead of having it suspended from a strap on the shoulder, that taphon is a drum placed on a stand. It is played with both hands using the palms and the fingers. This instrument is included in the Piphat ensemble. The ramana is a shallow drum that looks like a tambourine without the metallic discs. The diameter of its head is larger than the diameter of its body. Its frame is shallower and narrower than most soup plates. The thon ramana is a bowl-shaped ceramic drum that is used in the Mahori ensemble. Its head is made from various skins of goats, calves, and snakes. It is played with one hand covering and opening the open end of the body in order to control the tone and the other hand tapping the beat. Chordophones The jakhae or jakhe is shaped like a crocodile. Its body is big and hollow in order to resonate the sound of the instrument better. It is placed horizontally on the floor as the player sits on the ground. This instrument has a long neck, a sound box, and three strings attached to pegs. This is Thailand’s most important stringed instrument with the most beautiful sound. The saw sam sai resembles much the Japanese shamisen, but is triangular in shape with a spiked leg. Its body is made from coconut shells and calf-skin. It has three strings with no frets on the neck. The pitch of the string depends on the size of the coconut shell. Idiophones Ranat thum is a box-shaped metallophone that is placed on the floor and played while sitting.

Community College Students Essay

Often times, community college students are depicted by the public and the media as â€Å"not smart enough† or â€Å"not capable. † For example, just recently I was at Barnes and Noble and as I was looking for a book the sales associate approached me. She asked me if I needed help then asked me what school I attended, when I told her that I go to Fullerton College her attitude changed. She asked me if I didn’t go to a four year university because of my grades, when I told her that, that wasn’t the reason she went on ranting that I need to do good in school and I shouldn’t be at a community college. It seems that the public look down on the students at community college. When watching the show, â€Å"Blue Mountain State,† you have a group of friends that happen to be on the universities football team. On the show is portrays the typical university life and the football players engage in heavy drinking, drugs and lots of sex. If a four university is offering that then what is so good about going to one? Often times you hear about crazier parties thrown by universities rather than community colleges. Universities are supposed to be prestigious but these huge parties are throwing them off. Many times the public says that community college is no good because of its parties with drugs, they say that’s why no students should aim for community colleges but statistics say that universities throw the biggest parties. Who are the bad guys now? Recent talk on the website collegeconfidential. om, students talk about how their parents do not want their kids to go to a community college. This is a website for real people with answers from people who have had the experiences. A student just recently posted that his parents did not want him to go to a community college because they are no good. Many people were quick to respond to his post, most of the people who replied were adults who have had the experience, even some professors, and they told him that community college is not bad at all. The responders replied by saying that ommunity college has great professors and are cheaper than a four year university. Of course at a four year university you will get a bit better education, but for those who cannot afford the fees it is great for them. For example, a user , â€Å"NTKTOP,† posted this comment. â€Å"My parents say that they suck and that they’re going to kick me out of the house if I go to one. † This student sees nothing wrong with community college but his parents do, then this is what one San Diego State University graduate had to say, â€Å"I don’t think they’re bad. Of course, it depends on the school you choose and professor you get, but that’s the same of any traditional school. CC can be a good jumping board for some people. No matter where you go, you will find easy professors but in my experience CC is a not a bad choice. † This is my second semester in a community college; so far everything has been going good. The professors I have had are not very difficult but do not give easy grades. Last semester I had a Spanish class that was for advanced speakers but there were some things that did not click in my mind. My professor would stay with me after class to try and help me to better understand the material. This semester my math class has tutors that they offer for free. I take advantage of these resources because they are free and the professors are willing to help me out without any problem. The stories I hear from my friends in community college are that they have teachers that care for the student’s education; they do not give easy grades just because we are in community college. Many professors want to further our knowledge and prepare us for our transfer to a university. No matter where you go, you will get a great education. The United States is known worldwide for its prestigious schools. A big part has to come from the students, if the student is willing to put in the time, dedication and effort their possibilities are endless. So far, community college has been a great experience for me. I have great professors who are always able to help out. The media tries to pick on community colleges but in reality, it is a great choice in this economy. Many students that leave a four year university have a huge debt to pay because of loans. Many students choose community college because it is a fraction of the cost of a university. I do not think it is fair when parents judge community colleges as bad; you can get a good education for a very affordable price. You can go to a community college such as Fullerton College, which has great professors, to get your general education classes out of the way for a low price then transfer to a four year university to mainly focus on your degree classes.

comparing print and electronic essays

comparing print and electronic essays There are two types of media, the print and the electronic. The print media informs society through newspapers, magazines, and books. Electronic media publicly broadcasts news through radio, television, and recently computers. Both medias informs us on day-to-day events whether the news is local or worldwide but they have their differences. Through media our opinions are influenced and we become socialized. Even though print media seems to be factual and thorough enough, some still feel more partial to the nightly news on television. Hearing the stories is personally easier for society to understand and at the same time remains a reliable source. Because of its visuals, the television is especially powerful in transmitting realism (Graber, 189). Electronic media gives facial expressions and other images that the print media declines in. For example, actually watching the candidates interact with other people on television makes us feel as though we are able to get to know them better and understand their meaning of their decision that they are trying to get across to the American people. The electronic media gives an emotional impact on viewers by showing updated news in action. Journalists receive information during crisis minute by minute allowing them to quickly revise and deliver news to the public. However, the print media would have to wait until the next copy was printed for everyone to get the most recent news. By doing this, the newspapers leave a gap of information that electronic media has the capability to fill. Television shows people what has happened and what they are about to see. Since the journalists seem to put more thought into what they put on paper than what they would say on television, print media tends to more factual and analysis oriented. The print media goes in depth with their coverage where electronic media is straight- forward and only highlights the main topics. The n...

Never Put Off Till Tomorrow What You Can Do Today Essays

Never Put Off Till Tomorrow What You Can Do Today Essays Never Put Off Till Tomorrow What You Can Do Today Essay Never Put Off Till Tomorrow What You Can Do Today Essay More than 30 years ago the hypothesis of an interventional approach in patients with unstable angina or non–ST-segment elevation myocardial infarction (NSTEMI) was considered only after a cooling-off period. This negative attitude was in part justified by the lack of effective antithrombotic adjunctive therapies and devices in the management of lesion containing thrombus and the subsequent early hazard of percutaneous coronary intervention (PCI). The delay- many days or weeks after hospital admission- to interventional treatment could result in an apparent stabilization of the acute coronary syndrome (ACS) with a high incidence of early recurrent ischemia or nonfatal myocardial infarction (MI) in the more favorable cases or in a definitive cooling of the patients. During this long period many trials comparing an early invasive strategy with a conservative strategy in patients with unstable angina or NSTEMI have produced conflicting results that have delayed the current general consensus regarding the benefit of an early invasive strategy, which is more evident in high-risk patients and mainly driven by the decrease in MI and the need for percutaneous or surgical coronary revascularization. This troubled history might be explained at least in part by the design of most studies that randomized patients before cardiac catheterization and the use of a wide temporal windows- from 24 to 48 h to 5 days- for the definition of early intervention. Randomization before cardiac catheterization resulted in the enrolment of a high percentage (30%) of patients who did not receive coronary revascularization, because of mild or absent atherosclerotic coronary artery disease in most of them, making the comparison of an early invasive strategy versus a conservative or a delayed invasive strategy in selected patients distorted by the high number of patients at low risk of events whatever the strategy adopted. The use of temporal windows as long as 24 to 48 h to several days for the definition of an early treatment hides the potential benefit of a true early treatment (within 24 h of patient presentation) and contributes to maintaining considerable uncertainty about the optimal timing of cardiac catheterization and revascularization for patients with unstable angina or NSTEMI. The study by Sorajja et al. 1) in this issue of the Journal overcame these 2 critical points and provides important data on the impact of delay to PCI on clinical outcome in the large cohort of patients with ACS enrolled in the ACUITY (Acute Catheterization and Urgent Intervention Triage strategY) trial who underwent PCI (2). Patients who underwent PCI (7,749 patients) were stratified by time from hospital presentation to PCI into 3 groups: 24 h. A delay to PCI 24 h after clinical presentation was associated with 50% increase in 30-day and 1-year mortality as compared with patients who were treated earlier. Moreover, true early PCI was associated with a decreased rate of nonfatal MI. The incremental risk of death attributable to PCI delay 24 h was greatest in high-risk patients. The study results are consistent with those of the ISAR-COOL (Intracoronary Stenting With Antithrombotic Regimen Cooling-Off) trial (3). This elegant study is the only randomized trial comparing early intervention (delay to PCI 24 h after clinical presentation than among patients who had earlier PCI: no deaths at 1 year in the Thrombolysis In Myocardial Infarction (TIMI) risk score 1 to 2 subgroup with a time-to-PCI 2% in the subgroup with a time-to-PCI 24 h. This point is really important, because it outlines a major limitation of risk-scoring before cardiac catheterization in the individual patient and at the same time weakens a strategy of deferring for expedited cardiac catheterization only patients with a high risk score. A low TIMI risk score might correspond to a very-high-risk angiographic profile. This event is frequent and confirmed also by early coronary angiography in the PCI-ACUITY patient cohort (1). Nearly one-half of patients who underwent coronary angiography within 24 h of presentation had a baseline target vessel TIMI flow grade 2. A strategy of plaque passivation before PCI could be effective in decreasing PCI complications in the portion of patients who spontaneously or with an intensive antithrombotic treatment may experience improved coronary flow. Also in this subset of patients with an initial favorable course, the incidence of recurrent refractory ischemia is high- as is MI even after successful emergency PCI- whereas a remarkable portion of patients will not respond to antithrombotic therapy: in the ACUITY PCI study, 38% of patients who underwent coronary angiography with a delay 24 h still had a baseline target vessel TIMI flow grade 36 h after randomization). The difference between groups in the primary study end point (6-month death, MI, stroke) rate was not significant (9. % of patients in the early-intervention group, and 11. 3% in the delayed intervention group) (hazard ratio [HR]: 0. 85; 95% confidence interval [CI]: 0. 68 to 1. 06, p = 0. 15). As in previous trials with similar results, the lack of significant difference in outcome between the 2 strategies might be explained by the fact that the study could be underpowered for the primary end point (the study was stopped prematurely because of recruitment challenges ), involved mainly low-intermediate-risk patients with a subsequent low rate of PCI (
