Refer to the above table. Suppose the government commands each firm to reduce its emissions by 1 ton each and allows these two firms to trade pollution permits. If a 1-ton credit is sold for $175, the total cost for both companies combined to reduce emissions by a total of 2 tons could be as low as:
Directions: Identify the letter of the choice that best completes the statement or answers the question. Then mark your response on the answer sheet. Unless otherwise stated, demand curves are negatively sloped and supply curves are positively sloped. The midpoint and point formulae for elasticity are, respectively:
According to Colander (2010) Price Elasticity of Demand can be defined as “the percentage change in quantity demanded divided by the percentage change in price:
1a. Elasticity in the economics can demonstrate the consumer’s response to the change in a commodity’s price or other conditions.
National income and output are used in economic studies to estimate the value of goods and services produced in an economy a snapshot of a country’s economic activity. A system of national account is employed to account for and record economic changes. National income is calculated using a variety of different methods. Some of the more popular methods include GDP (Gross Domestic Product), GNP (Gross National Product), NNP (Net National Product), NNI (Net National Income) PI (Personal Income) and PDI (Personal Disposable Income), among many others.

“After producers raise the necessary capital, they negotiate contracts with all of the personnel who will be involved. This process can be difficult, because eleven different unions may be involved” (Pg.332)
If demand is perfectly inelastic, the demand curve is vertical. The supply curve shifts up by $1, and all of the incidence falls on consumers. Price increases by $1, and there is no change in quantity. Since 0, dP/d 1.

Price objections are one of the biggest obstacles salespeople have to conquer. There are two important points to keep in mind concerning price resistance. First, it is one of the most common buyer concerns in the field of selling. A salesperson must learn to negotiate skillfully in this area. Secondly, price objections may be nothing than an excuse.

Understanding why economies grow, allows governments to better provide for its citizens through evaluating public policies. More educated decisions by government allows for a good economy. A good economy allows citizens to save a larger percentage of their earnings. The citizens are then more likely to spend money on goods and services. Macroeconomic analysis allows businesses to understand how economies fluctuate, therefore providing the correct products at the right prices to their customers. Businesses make more money due to the spending of the citizens. Macroeconomic analysis allows businesses to make more informed business decisions. Businesses use their knowledge of macroeconomics to predict the effects of current public policies on interest rates, they then decide how and where to borrow the funds saved to purchase machinery and equipment that make their workers more productive and educated. Well-educated workforces allow firms to quickly adopt new technologies that increase worker
