...Competitive Analysis NURCAN DURAN Econ 202 November 9, 2014 GameStop is a privately held company based in the United States. They specialize in the sale of videogames and videogame systems. Their big draws are midnight releases of games and selling used games (at near new prices, sometimes, with only a five dollar difference in price for certain games that are still considered popular). GameStop has a strong presence in the niche of electronic home entertainment selling, buying, and trade-ins of new and used videogame systems and accessories GameStop also offer a rewards program to its customer that provides them with more incentives to encourage customers to trade in used games and electronics, which GameStop makes more money off of when they resell compared to new merchandise. There is not a lot of specific information available for GameStop. The primary fixed costs of GameStop are probably just rent they pay to the property owners where their stores are located. The primary variable costs include employee wages, utilities, and the costs of the products they sell (including goods bought from customers and trade-in values), which vary with demand and expected demand. Variable cost are probably the most important factor in the company’s performance. A new game can go from sixty dollars down to thirty dollars in just a few months after its release if there is not a high demand for it, whereas a more popular game may maintain a fifty or sixty dollar price tag for a year or...

...Phase 3 Individual Project Colorado Technical University Latasha Slidge ECON202-1303A-03 August 2, 2013 Instructor: Lance Brofman Technological change is the root of basic economic growth. To define Technological change, which is used to describe the invention, innovation and diffusion of technology or processes. Technological change can also be thought of as technological development, technological achievement and or technological progress. It is the start of the process and its diffusion throughout the process. Technological change has many different levels. Technological change includes products and quality gains for the existing product. The short run is defined as the time over which the length of operation is fixed and the only business decision that is available is the decision to hire and the number of employees to hire. The reason for this is because it’s easier to hire and fire workers than to change any major production processes or move to a new office. The short run decisions are based on the quantity of work and the quantity of capital and production processes will be fixed. Since Short run covers short-term processes and production changing our processes with our new innovative ideas will not help the business. Thinking in terms of short run the fixed costs are paid and are unrecoverable so any changes with the processes of the company and its costs will be unrecoopable thus the changes are or will most likely be ineffective. In short...

...ECON202 7 December 2014 Social Security and its Deficits In 1935, after bank failures and a stock market crash had wiped out the savings of millions of Americans, the nation turned to their president to guarantee the elderly a decent income. In those days, only a handful of workers had access to pensions from their employers or through State governmental pension programs. Over half of America's elderly lacked sufficient income to be self-supporting. The Social Security Act was enacted at the urging of President Franklin D. Roosevelt to create a social insurance program that ensures workers would have a source of income after they retired. (ssa.gov, n.d.)  In the decades that have followed, Social Security has become one of the federal government's most popular and essential programs. Despite all our efforts to encourage savings and investment, the private retirement picture has not changed much in recent decades. Even today, barely half of all workers have access to retirement plans at work, and millions reach retirement age without enough private savings to provide an adequate living in retirement. Social Security is still the foundation for most seniors' retirement. Without this critical safety-net program, over half of all older Americans would fall into poverty. Social Security does exactly what it was designed to do. It gives retired people a secure, basic income for as long as they live. At the end of 2005, more than 48 million people were receiving Social Security benefits:...
