...The Ricardian model is a simple picture of international trade between nations, which was created to show comparative advantage in producing goods and the gain from trade. The concept of comparative advantage was introduced by David Ricardo in 19th century. The country has comparative advantage in producing certain product if it can produce it at a lower cost than any other country. The Ricardian model has been developed on following assumptions: * Only two countries are involved in activities; * Only two goods can be produced; * Labor is the only factor of production. The Ricardian model is a useful key for economy, because it explains why trade between countries can happen and how it will effect national welfare (Krugman, 2012). Countries should export a product in which they are most productive to fulfill the prediction of the Ricardian model. The principal of the model is defined by specialization, meaning countries specialize in goods they export. This will not hold in the data. However, the prediction that countries tend to export those goods they have high labor productivity is confirmed in data. Since 1950s, there has been a few attempts to empirically test the validity of the comparative advantage theory. McDougall, Stern, and Balassa have claimed that they found confirmation for the model by using the data from World War II. However, later researches have criticized this model, and fallacies have been found (“International Trade Relations”, 2014). ...

...The Ricardian model provides an introduction to international trade theory. This most basic model of trade involves two countries, two goods, and one factor of production, labor. Differences in relative labor productivity across countries give rise to international trade. This Ricardian model, simple as it is, generates important insights concerning comparative advantage and the gains from trade. These insights are necessary foundations for the more complex models presented in later chapters. The text exposition begins with the examination of the production possibility frontier and the relative prices of goods for one country. The production possibility frontier is linear because of the assumption of constant returns to scale for labor, the sole factor of production. The opportunity cost of one good in terms of the other equals the price ratio since prices equal costs, costs equal unit labor requirements times wages, and wages are equal in each industry. After defining these concepts for a single country, a second country is introduced which has different relative unit labor requirements. General equilibrium relative supply and demand curves are developed. This analysis demonstrates that at least one country will specialize in production. The gains from trade are then demonstrated with a graph and a numerical example. The intuition of indirect production, that is "producing" a good by producing the good for which a country enjoys a comparative advantage and then trading for...

Using a Ricardian continuum of goods model it is shown that under uncertainty a trade-off emerges. As in the standard deterministic model, higher trade integration reduces prices and increases expected real income. However, higher trade integration, reducing the number of active sectors in the economy, also increases the displacement cost the worker suffers when the sector she is employed into has to close down because, ex-post, the foreign country’s competing sector results to be more efficient. Two are the main results of the model. First, it is shown that, under uncertainty and job specificity, increasing trade integration is not always welfare enhancing...

...the right hair, and covering nothing up but your crotch area. This interprets sexuality. The same goes for women. typical images for women are a big chest, a big behind, slim waist, long legs, skinny, oh and flawless. The stereotypes these advertisements perpetuate are that men are supposed to be taller, bigger, heartless, and tough. As for women, they have to be smaller, looked down upon, and even always being innocent. When it comes to race, a white boy has control over the white girl. But when it's a black boy and a white girl, the girl has the control. Go figure that race would have a part in advertisement. Another way race is involved in this is when it comes to colored women, they're seen as animals. They would dress up the colored models into an animal such as a tiger and have her pose as...

...comparison between model in the past and the present, and how models become more restraints than before. Also we will talk about the advantage of using models and how they can make our life much easy. Models have evolved since the beginning of the century. There are many kinds of models for almost any system or item that exist. Each model uses short, long, simple or complex mathematics formula it depends of which case the models solve. However the models that are used in these recent years are very complex and have many numerous computations which make the only one that can handle it is the computer. These kinds of models are usually use in a wide variety of tasks, such as prevision of the decision made, and an effective answer to everyday problems. During time, models start to be more restraints than before. These kinds of restraints should have value or weight to make a model compatible with the case that model solve. There are several constraints or restraints in each models, one of the most important one is budget of the project. In other words the more wherewithal, the more model accuracy. Mark P. McDonald ( December 8, 2010). To use complex mathematical formula in the models it requires an educated staffs with a good knowledge of model branch, which make the model more expensive and take more time to solve it, comparing with computer time and cost. However the need of special educated persons is strictly required to conclude if the models created by computer...

...superior performance in a given job, role, or situation.Competency modeling is the activity of determining the specific competencies that are characteristic of high performance and success in a given job. Competency modeling can be applied to a variety of human resource activities. This research paper will describe how organizations identify their core competencies and how they are applying this competency data to improve performance. It will also explain some emerging trends in competency modeling. Developing Competency Models Competencies enable employees to achieve results, thereby creating value. It follows that competencies aligned with business objectives help foster an organization's success. Organizations must understand their core competency needs - the skills, knowledge, behaviors, and abilities that are necessary for people in key roles to deliver business results.According to Boulter, et al (1998), there are six stages involved in defining a competency model for a given job role. These stages are: 1. Performance criteria - Defining the criteria for superior performance in the role. 2. Criterion sample - Choosing a sample of people performing the role for data collection. 3. Data collection - Collecting sample data about behaviors that lead to success. 4. Data analysis - Developing hypotheses about the competencies of outstanding performers and how these competencies work together to produce desired...

...1. MACRO ENVIRONMENT Social Forces Two publicly controversial issues in the modelling industry are slenderness and racial exclusion. Models do much more than promote the sale of fashion. The model look promotes and distributes ideas about how women and men should look. Models “do gender” professionally in ways that connect with social positions such as race, ethnicity and class, and there are many critiques of fashion models and their gendered and racial meanings. Modelling succeeds on the criticism of the female body and the gap between promoted beauty ideals and reality. As women gain political and social ground, beauty ideals are held to higher extremes of slenderness and perfection. Another social force for clients is they face uncertainty of changing consumer desires as they are highlighting the importance of healthy lifestyles and body types. Demographics For fashion models age is a very strong factor in the selection process. Models are usually discovered between the ages of 12 to 20 by agents or scouts. High fashion modeling agencies often demand height and body shape requirements and have strong preferences for standards. With cultural diversification of the Western world, ethnic diversity is becoming an important factor for all people in the modeling industry. Moreover, various races and backgrounds are becoming progressively noticeable. Anita Norris needs to be aware of the changing demographic trends in the modeling industry Technological Factors...

...beauty whether it is appearance, their personality or the work they have done. Looking into celebrity culture, people follow it to help them feel beautiful or use celebrities as motivation. Celebrities are our role models and we try to follow them in the latest fashion like clothing, hair, make-up and acting. Teens especially want an iconic person to look up to and follow them for their selflessness deeds and actions. Celebrities like Tyra Banks, Oprah Winfrey, and Queen Latifah are example of iconic celebrities that many people look up to and try to mimic in order to feel self-fulfilled. Celebrity culture does help define our view of beauty for men and women worldwide. The celebrity culture is in our lives every day, people try to copy them in any way possible because they are they’re our role models. Tyra Banks is an exceptional model that has been through many difficulties as an African American model. She faced racism as a child when she first began her modeling career. As she was getting older she began to put aside all the harsh comments and continued her passion for modeling. Tyra Banks was the first black young woman in the modeling business. As she was growing up, she became very famous because of her age, origin, and difficulties she faced as a young model. Many teens started to look up to her and wanted to be just like her.

...body image, which can lead to unhealthy behaviors as women and girls strive for the ultra-thin body idealized by the media. This essay will attempt to prove that the media has a brutal effect on a women’s confidence. First, the media portrays that beauty is a necessity for all women. Unfortunately, the media pushes an unnatural body type, making natural beauty impossible to accept. The average American woman is 5\'4\" tall and weighs 140 pounds. Where as, the average American model is 5\'11\" tall and weighs 117 pounds ( Nikki Katz). Society is being brainwashed by the media. In fact, studies show that more than sixty percent of women do not like what they see in the mirror (Rutherford). Also, at young ages girls are impacted by the physical appearance of Barbie. Many people do not understand that looking like Barbie is physically impossible. Moreover, the models women see in magazines are completely flawless, and have incredible bodies. The majority of society could never look as good as the models they see. To summarize, women are discouraged with their bodies because the media only show beautiful...

...Computer Simulation: The process of computer simulation is mainly used for the purpose of generating an abstract model of a specific system. The way how system behaves can be shown by this along with few other activities involving constructing, designing and defining a model of a system. Simulation can be defined as mimicking or imitating through experimentation with a model of some real system Importance of Simulation: To lead a day-to-day life, many industries such as Healthcare, Military, Retail, Logistics etc. also makes use of these simulation models for their routine work to be done in an effective way. When these industries face problems they can be solved by acquiring the knowledge of simulation software which can be obtained by the use of analysis and modeling Simulation & Modeling can be used in various areas such as: In call centers- Simulation used in call centers is mainly to assure customer satisfaction. Simulation helps in predicting various calls and analyzing the agents to work on each type of call. Agents are trained in such a way that the waiting time for the incoming call should not be increased and one should respond to it immediately to answer customers queries managing their own time. This way customer satisfaction can be obtained handling numerous calls per day. Therefore simulation helps in call centers to plan and manage the workforce accordingly.
