market

A group of economic agents who are trading a good or service would define a

economic agent

An economic agent is any individual or group that makes choices. This means that any decision maker is considered an economic agent. This includes​ consumers, parents,​ students, firms, and universities as well as​ workers, senators,​ criminals, and sports teams

C.

economic agent

An is an individual or a group that makes choices.They make decisions by solving choice problems. Each of the may play multiple roles in the economy for example​ households, may act as a consumer or worker according to their choice and has an effect on the economy. Economists simplify their analysis by treating these groups as a single decision​ maker, without worrying about the details of how the different individuals in the group contributed to the decision.

We must first translate the mortality and morbidity data into dollars in order to compare it to the costs of the regulations.

The costs of many food safety regulations can be calculated in​ dollars, but the benefits often are in terms of lives saved​ (mortality) or decreases in the incidence of a particular illness ​(morbidity). What does this imply about the​ cost-benefit analysis of food safety ​regulations? A.We must first translate the mortality and morbidity data into dollars in order to compare it to the costs of the regulations. B.Since these are government​ regulations, a​ cost-benefit analysis is not needed because the government acts independent of such analysis. C.Since the benefits of these regulations are not in dollar​ terms, a​ cost-benefit analysis cannot be done. D.Since the costs are incurred by the government and the benefits are enjoyed by the​ consumer, such an analysis is meaningless.

D.Elasticity depends on more variables than does slope.

positive economics

describes what people actually do. In this​ case, predictions are testable​ and, therefore, can be rejected or amended depending on the evidence available.

A.

hat is the difference between marginal values and average​ values? A.Marginal values show the additional benefit or cost from consuming an additional unit of a​ good, while average values are the benefit or cost per unit of a good. B.Marginal values show the total benefit or cost from consuming a​ good, while average values are the total benefit or cost from consuming a good divided by the amount of the good consumed. C.Marginal values show the benefit or cost from consuming one unit of a​ good, while average values are the benefit or cost from consuming all units of a good. D.Marginal values show the benefit from consuming an additional unit of a​ good, while average values are the cost from consuming an additional unit of a good. E.Marginal values show the ordinal benefit or cost from consuming an additional unit of a​ good, while average values are the cardinal benefit or cost from consuming an additional unit of a good.

cost-benefit analysis

is a calculation that identifies the best alternative by summing benefits and subtracting​ costs, with both benefits and costs denominated in a common unit of measurement such as dollars. In​ essence, it is weighing the pros and cons of a decision in order to determine what to​ do, which is what normative economic analysis is all about.

normative economics

is analysis that recommends what an individual or society ought to do. In this​ case, the town residents may be better off​ financially, but it will be at the expense of another​ group, the trucking industry.
