Critics argue that there are myriad of factors that impact a consumer and business that might make their choices or decisions irrational. Some economists assume that people make rational decisions when purchasing or investing in the economy. Homo economicus is a term that describes the rational human being assumed by some economists when deriving, explaining, and verifying theories and models. Economic order quantity is defined as the ordering quantity which minimises the balance of cost between inventory holding costs and re-order costs.Underlying assumptions in an Economic Order Quantity model are: That there is a known, constant stockholding cost; That there is a known, constant ordering cost, That rates of demand are known, To study the effects of international trade, for example, we may assume that the world consists of only two countries and that each country produces only two goods. Revise the model if it fails to explain the economic data well. The scientific method requires isolated variables and testing to prove causality. If the economic order quantity model is applied, the following assumptions should be met: 1.

According to economists, there are five basic assumptions that we make regarding economics: 1. The framework is usually based on mathematics, and most models make several assumptions about how people behave and how the modeled economy operates.
