1. The willingness to pay is the value that the consumer puts on the good. Every person puts a different value on everything from material things to natural resources. Having money and being able to pay for goods plays a big part in a person willingness to pay. Willingness to pay relates to demand in the way that there is a market curve for the goods that an individual is willing to pay for the goods. First you start with a high price on the good and see how many buyers will be willing to pay for that good at that price. Then you lower the price and see what happens with the consumers. Doing this you can follow the trends and see what price a good is at when a consumer’s willingness to pay is at its peak. Every consumer has a different demand curve and it depends on their wealth and what they can afford to see their willingness to pay. (Field and Field 2009) 2. There are many things to consider when it comes to the cost of manufacturing a product. To determine to cost of manufacturing you need to know the costs required for the business, in production, the cost of selling a product to determine the price and when the product is sold, was there a profit or loss. The cost of manufacturing a good include the costs of materials, equipment, labor, materials for packaging, electricity and water, transportation, promotion and advertising, management and coordination and depreciation of fixed assets. (FAO) Things to consider when producing a plastic product would be what the plastic is going to be used for, will it be a bearing and wear application or a structural application, thermal requirements, what chemicals will be used to clean it, tensile elongation, tensile impact strength, water absorption, and how cost effective is the production. There are so many things to consider and to many to list. 3. 4. Economists make assumption like “nothing else changes”
