...9P The new equilibrium price is P* = $2.19 per pound. An increase in demand of 20 percent, therefore, increases price by 19 cents per pound, or 9.5 percent. b) Using the new price of $2.19 in the supply curve, the new equilibrium quantity is Q* = - 6 + 9(2.19) = 13.71 million metric tons /year, an increase of 1.71 million metric tons/ year. c) The new supply of copper falls (shifts to the left) to 80 percent of the original, so Q ́S = 0.8QS = 0.8(-6 + 9P) = - 4.8 + 7.2P. The new equilibrium is where Q ́D = Q ́S. 21.6 – 3.6P = - 4.8 + 7.2P. The new equilibrium price is P* = $2.44 per pound. Plugging this price into the new supply equation, the new equilibrium quantity is: Q* = 4.8 + 7.2(2.44) = 12.77 million metric tons/ year. Exercise 10: a) The competitive (non-OPEC) quantity supplied is Sc = Q* = 20. The general form for the linear competitive supply equation is SC = c + dP. the short-run supply elasticity as ES = d(P*/Q*) where d is the slope of the supply function. Since ES = 0.10, P* = $50, and Q* = 20, 0.10 = d(50/20). d = 0.04. Substituting for d, Sc, and P in the supply equation, c = 18, and the short-run competitive supply equation is Sc = 18 + 0.04P. Similarly, world demand is D = a - bP the short-run demand elasticity is ED = - b(P*/Q*), where Q* is total world demand of 34 and b is the slope of the demand...

They can also use unconventional methods to obtain results. * Enthusiasm to work: All said and done, in the end for any rural venture to be successful, what is required is a very high degree of enthusiasm, and an urge to excel. Social work is usually characterized by long working hours, unclear goals, sensitivity towards culture, commitment to the goals. Most private ventures enter this field out of passion and hence have this in plenty. Government officials may or may not be passionate about this project, but have to work on it.

The Day My Business Changed

...I was sitting in a Portland Oregon hotel when four words forever changed my business. The keynote speaker at the meeting, a vice president of channel had just finished a surprisingly lack-luster presentation and opened up for questions. An associate from New York City immediately stood and asked, “Do you consider us competition or partners?”  The VP answered without skipping a beat,  “You are Apple’s competition.” I guess there shouldn’t have been a gasp and rumble throughout the room, but 100+ Authorized Resellers and VARs suddenly realized that they faced an uphill battle. Many would close their doors in the months to come. As an Authorized reseller I bought our Apple branded products from first tier distributors such as Ingram Micro and Tech Data with only small price variances based on the size of the Purchase Order. Smaller PO’s were often ignored or faced delays in shipping. A big reason for the gasp in the room was the increasing trend of Apple product scarcity for resellers. While Apple’s new retail stores had full shelves we had to fight over the leftovers. Often this meant we missed out on the initial surge of purchases made by early adopters. (Eventually Apple would release game-changing products like the iPhone and not allow Apple resellers to sell them.) When Apple opened their new store 5 minutes from one of mine I was forced to pivot or close my doors. We changed from being an Apple Reseller who sold some accessories to more of a system integrator and service...

Ribbons and Bows

...Ribbons and Bows INTRODUCTION Carmen Diaz, with a ten thousand dollar loan from two of her cousins, and one thousand dollars that she invested in equity, was able to open a specialty store called Ribbons an’ Bows, Inc, which was located in Coconut Grove, Miami, Florida. Four months after opening the business, Carmen’s relatives requested a financial report, which was part of the original business arrangement. Within a short time, Carmen had expanded the business, purchased small equipment, paid wages to a part-time employee, and by all outward indicators, had been running a flourishing business. As Carmen gathered the necessary information to prepare financial statements, she started to scrutinize the transactions and was somewhat perplexed. Carmen realized that numbers were not adding up as she had anticipated. Additionally, it became questionable whether the business was operating successfully, at least when accounting principles were appropriately applied.  Statement of the Problem It was fortuitous for Carmen Diaz to have family who were supportive of her small business endeavor, thereby providing start-up funds and legal advice. Carmen’s endeavor can be recognized as a “microbusiness” operation; “microcredit”, microenterprise” and “microfinance” are terms that have been associated with microbusinesses (Datar, 2009). Clearly, Carmen would have benefitted from some professional entrepreneurial guidance that is widely available at no cost in the United States...

My personal experience with my injury affected me the most during my training at Fort Jackson, South Carolina. I had injured my knee half way through my training and found that everything was more difficult to deal with from there on out.

While in training, I had to wake up an hour early every morning to report to physical therapy for my knee, I did this for about 5-6 weeks.

Information

...Karides, Florida Atlantic University An economic leader in the Caribbean, the Republic of Trinidad and Tobago has incorporated micro-business development as one of its main strategies to alleviate poverty and unemployment and to spawn economic growth since the late 1980s (ILO 1991, 1998, Ministry of Finance 1996). Although the discovery of natural gas in the early nineties catapulted Trinidad’s economic growth rate to four percent per annum, unemployment and poverty continue to affect a large portion of the population. The majority of the population has not benefited from Trinidad’s economic growth. Thus, the government has attempted to create “a nation of entrepreneurs” in order to relieve some of the inequality that defines the society (Ministry of Trade and Industry 1997). Trinidad’s expansion of micro-enterprise programs reflects an international trend. Endorsed by non-governmental organizations, private financial institutions, international development agencies, including the World Bank, many scholars and development practitioners also view microenterprise assistance as a panacea for Third World poverty (Johnson and Kidder, 1999; Mosley and Hulme, 1998; Dignard and Havet, 1995; Grosh and Somolekae, 1996; Rakowski, 1994). Micro-enterprise development programs generally consist of training in business skills or providing small loans or credit to micro-entrepreneurs (Dignard and Havet, 1995; International Labour Organization, 1995; Rakowski, 1994). These programs typically target...

...through physical and mental exercise and deep relaxation. Although known to be at least 5,000 years old, yoga is not a religion and fits well with any individual's religious or spiritual practice. Anyone of any age, religion or life condition can practice yoga and derive its benefits. Yoga is the practice of putting the body into different postures while maintaining controlled breathing. It is considered to be a discipline that challenges and calms the body, the mind, and the spirit. By focusing on the breath entering and leaving your body, you are performing an exercise in concentration.

Last fall her son, Mikey was diagnosed with cancer. I can't even begin to describe the overwhelming devastation and complete sadness this brought to our family.
