...The Inaugural Coase Lecture An Introduction to Regression Analysis Alan O. Sykes* Regression analysis is a statistical tool for the investigation of relationships between variables. Usually, the investigator seeks to ascertain the causal effect of one variable upon another—the effect of a price increase upon demand, for example, or the effect of changes in the money supply upon the inflation rate. To explore such issues, the investigator assembles data on the underlying variables of interest and employs regression to estimate the quantitative effect of the causal variables upon the variable that they influence. The investigator also typically assesses the “statistical significance” of the estimated relationships, that is, the degree of confidence that the true relationship is close to the estimated relationship. Regression techniques have long been central to the field of economic statistics (“econometrics”). Increasingly, they have become important to lawyers and legal policy makers as well. Regression has been offered as evidence of liability under Title VII of the Civil Rights Act of , as evidence of racial bias in death penalty litigation, as evidence of damages in contract actions, as evidence of violations under the Voting Rights Act, and as evidence of damages in antitrust litigation, among other things. In this lecture, I will provide an overview of the most basic techniques of regression analysis—how they work, what they assume, Professor of Law, University of Chicago...

...Chapter Eight Case Study - Coke Zero Coke Zero Coca Cola has been the leader in the soft drink market for decades, consistently besting their nearest competitor, Pepsi. The struggle for the top spot has been on-going for over one hundred years, and at times has been fairly interesting. Both companies have been trying new strategies, flavors; can designs and even recipe changes in order to gain market share, niche competitive advantage as well as a sustainable competitive advantage. (Lamb, Hair Jr., & McDaniel, 2013, p. 26) Both companies constantly change their products and their marketing techniques in order to secure an advantage over one another. Coca Cola over the years has used common good business practices in order to evaluate their business, so they would know which direction to take it, next. Sometimes their choices were effective, other times they were not. A Coca-Cola marketing situation comes to mind going back to 1985, when seemingly out of the blue, Coke changed their formula. The onslaught of public outcry then began, forcing Coca Cola to re-think their strategy and into damage control mode. It was either a brilliant strategy designed to be a publicity stunt, or one of the worse blunders ever in corporate America. The answer is still not clear to this day, however the results were interesting and have been fodder for Marketing classes ever since. News about the “New Coke” dominated the airwaves for weeks on end, and people rushed out to try it. Most did...

...biggest and best-known brand. It sells 1.4 billion soft drinks per day and makes more than $5 billion profit per year. Yet Coca-Cola is scared. Throughout the west, fizzy drinks are seen as unhealthy; and the richer people get, the more they worry about health, fitness and their appearance. Coke is no longer ‘it’. In 2004 and 2005 Coca-Cola sales were actually falling in America and Europe, for the first time since the brand’s birth in 1886. The brand may be struggling, but the company itself is fighting fit. The 2006 launch of Coke Zero was a huge success in America and Britain. The idea of ‘Bloke Coke’ showed great marketing understanding in a market where Diet Coke is largely targeted at 20-30 year old women. In the first 16 weeks from its July 2006 launch, Coke Zero sales were £24.1 million, the biggest launch success of any new grocery product for the last 3 years. The success of Coke Zero has reversed the sales drift among men. But what about women? Autumn 2007 sees the next stage in coca-cola’s marketing strategy: the launch of diet coke plus. Diet coke has been a fantastic success since its launch in 1982. Its 25th birthday has been celebrated in 2007 through a special silver can (very hard to get hold of). Diet coke has been called ‘the greatest extension strategy in business history’. In the UK Diet Coke’s silver can often outsells coke’s red one. But although it meets the consumer demand for low calories, diet coke cannot offer the positive health benefits claimed...

...Analysis of Major Characters→ Nawal El Sadaawi Nawal El Sadaawi is both the author and the narrator of Woman at Point Zero. As the author, she presents a fictionalized version of two real people: Firdaus and herself. Though the fictional characters closely resemble the two real people, they are distinct. The fictional El Sadaawi struggles with feelings of insignificance, and by the end of the book she is consumed with helpless rage over the condition of women, including herself, in her country. Undoubtedly, the author El Sadaawi also has these feelings, but by the time she wrote Woman at Point Zero, she had long been a significant figure in her country’s consciousness, as well as a crusader for women’s rights. The fictional El Sadaawi is first introduced when she visits the prison in which Firdaus is awaiting her execution. El Sadaawi approaches her meetings with Firdaus with desperation. Firdaus is an imprisoned prostitute, and El Sadaawi, an educated and wealthy doctor, occupies a much higher social position. Still, El Sadaawi is devastated by Firdaus’s initial refusal to be interviewed; it makes her feel insignificant. When Firdaus finally agrees to meet El Sadaawi, El Sadaawi approaches her like a petitioner. This is because El Sadaawi, despite her education and status, is still subject to discrimination and feels insignificant most of the time. Because the imprisoned Firdaus refuses to be “put in her place,” El Sadaawi suspects that Firdaus might have some sort of strength...

...Spandana Case Study: An Analysis This essay is based on the first randomized Impact evaluation of Microfinance. Section 1 explains the methodology of the study, Section 2 presents the data analysis and results, Section 3 presents the Caveats to be considered while interpresting the results, Section 4 presents some conclusions derived from the study and Section 5 talks about how some of the problems identified with respect to MFIs can be addressed. In a paper named “Miracle of Microfinance: Evidence from a randomized evaluation”, Abhijit Banerjee, Esther Duflo, Rachel Glennerster and Cynthia Kinnan analyze the first randomized evaluation of the impact of introducing the standard microcredit group-based lending product in a new market. This study also follows the households over the longest period of any evaluation (three to 3.5 years after the introduction of the program in their areas) to trap impacts not only in the short run but also over the medium run. The results of this study compel us to think about the functional difference that the microfinance initiatives are making in the target community and whether it’s time to address this sphere of developmental finance with less fancy and more caution. SECTION 1: METHODOLOGY OF THE STUDY CONSTRUCTION OF THE RCT Baseline Survey A baseline neighbourhood survey (2005) was conducted to assess baseline conditions such as household composition, education, employment, asset ownership, expenditure, borrowing, saving, and any businesses...

...this paper, I have focused upon the women employees for finding their causes of absence inside the organization. There are about 427 females working in this organization and are working in Departments A and B. 1.2 Analysis and interpretation of the data i. The average age of the working women in this organization is 37.52 years. The youngest employee is with the age of 21 and the oldest employee is with the age of 63. This shows that, there are employees who are reaching the age of 40s, and hence, can suffer from several traumas and diseases. ii. The average working days for these women is found to be 17.78 days. Therefore, out of the given approximately 25 working days, the working output is approximately 71.12%. This can be improved by reducing the number of absentees. iii. The average hour during which a particular employee remains sick is 11.94 hours. This shows that during these hours these employees will be remaining non-productive. In addition, in addition, they might take leave for the entire day, even if they feel low for just one hour. This is shown in Chart – 1. They are shown for a sample size of 25 female employees. iv. The average sick costs per woman employee come out to be $132.90. Therefore, if we consider these costs for all the women employees, it will be approximately £56748.30, which is a huge amount, considering one working month. In addition, in addition, the productivity will be zero during that point in time. This is shown in...

...Introduction “Question: How much money does the United States spend on public elementary and secondary schools? Response: Total expenditures for public elementary and secondary schools in the United States amounted to $632 billion in 2010–11, or $12,608 per public school student (in constant 2012–13 dollars, based on the Consumer Price Index). These expenditures include $11,153 per student in current expenditures for operation of schools; $1,076 for capital outlay (i.e., expenditures for property and for buildings and alterations completed by school district staff or contractors); and $379 for interest on school debt. From 2000–01 to 2010–11, current expenditures per student enrolled in the fall in public elementary and secondary schools increased by 14 percent (from $9,751 to $11,153 in constant 2012–13 dollars). The amount for 2010–11, however, was lower than the amount for 2009–10 ($11,353).” 1 This increasing trend in US educational spending has existed for decades. It is only during economic downturns that the growth trend has stalled or had minor inversions, like mentioned in the excerpt above for 2009-10. It should also be noted that the growth trend of these dollars typically outpace the growth trend of CPI inflation. In other words, the percent of GDP that goes towards public education has been on the rise. Why the growing trends? Many believe that education is worthwhile because of the financial flexibility it affords individuals especially during the...

...the least. There are many resources that explain the pros and cons of leaving the toilet seat in the downward position. For example, an article written by Martin A. Andresen, “Up or Down? An Efficiency-based Argument for Optimal Toilet Seat Placement”. Andresen theorizes that there is an actual mathematical equation that can be used to determine efficiency. Andreson concluded, “…results clearly show that if the number of females is greater than or equal to the number of males the optimal placement of the toilet seat is down” (Andresen). After reading Andreson’s commentary, while this theory is somewhat valid, coming up with an actual equation for solving this problem is a bit much. For example: (Andreson) “This ratio is bounded by zero and unity. If the TSR is greater than 0.50, the optimal toilet seat placement is up; if the TSR is less than 0.50, the optimal toilet seat placement is down; and if the TSR is equal to...
