  • Analyze the impact of both imperfect information and asymmetric information
  • Evaluate the role of advertisements in creating imperfect information
  • Identify ways to reduce the risk of imperfect information
  • Explain how imperfect information can affect price, quantity, and quality

Consider a purchase that many people make at important times in their lives: buying expensive jewelry. In May 1994, Doree Lynn bought an expensive ring from a jeweler in Washington, D.C., which included an emerald that cost $14,500. Several years later, the emerald fractured. Lynn took it to another jeweler who found that cracks in the emerald had been filled with an epoxy resin. Lynn sued the original jeweler in 1997 for selling her a treated emerald without telling her, and won. The case publicized a number of little-known facts about precious stones. Most emeralds have internal flaws, and so they are soaked in clear oil or an epoxy resin to hide the flaws and make the color more deep and clear. Clear oil can leak out over time, and epoxy resin can discolor with age or heat. However, using clear oil or epoxy to “fill” emeralds is completely legal, as long as it is disclosed.

After Doree Lynn’s lawsuit, the NBC news show “Dateline” bought emeralds at four prominent jewelry stores in New York City in 1997. All the sales clerks at these stores, unaware that they were being recorded on a hidden camera, said the stones were untreated. When the emeralds were tested at a laboratory, however, it was discovered they had all been treated with oil or epoxy. Emeralds are not the only gemstones that are treated. Diamonds, topaz, and tourmaline are also often irradiated to enhance colors. The general rule is that all treatments to gemstones should be revealed, but often disclosure is not made. As such, many buyers face a situation of asymmetric information    , where the both parties involved in an economic transaction have an unequal amount of information (one party knows much more than the other).

Many economic transactions are made in a situation of imperfect information    , where either the buyer, the seller, or both, are less than 100% certain about the qualities of what is being bought and sold. Also, the transaction may be characterized by asymmetric information, in which one party has more information than the other regarding the economic transaction. Let’s begin with some examples of how imperfect information complicates transactions in goods, labor, and financial capital markets . The presence of imperfect information can easily cause a decline in prices or quantities of products sold. However, buyers and sellers also have incentives to create mechanisms that will allow them to make mutually beneficial transactions even in the face of imperfect information.

If you are unclear about the difference between asymmetric information and imperfect information, read the following Clear It Up feature.

What is the difference between imperfect and asymmetric information?

For a market to reach equilibrium    sellers and buyers must have full information about the product’s price and quality. If there is limited information, then buyers and sellers may not be able to transact or will possibly make poor decisions.

Imperfect information refers to the situation where buyers and/or sellers do not have all of the necessary information to make an informed decision about the price or quality of a product. The term imperfect information simply means that not all the information necessary to make an informed decision is known to the buyers and/or sellers. Asymmetric information is the condition where one party, either the buyer or the seller, has more information about the quality or price of the product than the other party. In either case (imperfect or asymmetric information) buyers or sellers need remedies to make more informed decisions.

Select inflation type, Demand pull, cost pull or anticipation 1- Select the set of data you intend on graphing i.e inflation rate of 2017, location (particular country) 2 - Select the type of measurement tool that best allows you to input the inflation data, Consumer price index is the most accurate
this is to make sure you have all the correct information, Also use should know 1- Cost pull is Aggregate Demand and Aggregate Supply AD - AS graphed 2- Demans pull is Aggregate Supply and Aggregate Demand AS - AD graphed

Economics is a social science because it study human behavior how he relates with his daily activities with the available limited resources to satisfy his wants.
what are the factors affecting the demand
yeah it uses the scientific method to study human behaviour.

what the difference between Trade off and Opportunity Cost?
In trade off, you increase the amount of something by decreasing the amount of something else. For example, you use 2 hours to study and 2 hours for leisure. if you increase study hour by 1 more hour, i.e 3 hours, leisure time will decrease by 1 hour, i.e 1 hour.
In all, you would have traded off 1 hour of leisure time for 3 hours of study time. But in opportunity cost, you let something go in order to obtain something else entirely.

different between demand and quantity demand
Farhan Reply
No difference
demand is the overall demand for it
actually theres no difference
quantity demanded is used in Equilibrium of d and s
for evrything else u use deman
the difference of it is that when demand simply denotes the willingness and a person's ability to purchase. And as against quantity demand represent the amount of an economic good or services desire by a consumer at a fixed price .☺

what are the methods used by trade union to increase wages of their members?
Black Reply
the size of the commodity
increase demand of labour decrease supply of labour
I do support your answer Jackel.
but how do they do it?
by increasing more labour and reduced the suppliers
they can not increase labour, they increase demand of labour.
how do they increase demand for labor?
by analyzing the market equilibrium , cost reduction and cost control , savings in time .
decreasing supply of labour are achieved through training and certification that require for you to employed, you must have certificate, also trade union encouraged government to restrict migration into the country causing shortage of labour supply. Note that the aim of union is to enhance life
objective of union: better working conditions, liveable wage, protect member from unfair treatment which are done through negotiations betweens representative and management. known as collective bargaining.
