Abstract: Models are abstracts of reality and the primary objective for ‘modeling` is to provide us with the ability to manipulate reality without causing any destruction. But for a model to be useful it has to be requisite, that is, it must contain all the relevant variables of the reality it intends to represent. Usually, economic models do not spell out the procedures by which decisions of the economic unit are made; moreover they tend to be generic without any discrimination on aggregate variables for decision makers, like culture. If anything at all, behavioural models capture cultural influences implicitly. This study is the report of a study to establish and document how investment decisions are made, paying particular attention to the nature of the factors that determine how the prospective investor goes through the choice of investment instruments. It is an attempt to explicitly capture the influences of culture on the decision making process. An attempt to find an answer to the question as to why traders in Ghana engage in a savings which requires that they make a payment for the savings instead of depositing the money in a savings account with a bank where they would have received interest on it. The present study was motivated by the suspicion that a hidden cultural factor influenced this rather strange phenomenon. Generally Western thinking is that investment decisions must be fully analytical. Consequently, several organizations exist with the primary objective of providing information to assist in the careful and systematic analysis of investment opportunities. But this presupposes that the decision maker himself is analytical in his thinking, which is only true if considered in Western environments. Unfortunately, that may not hold true in other societies, as the observed phenomenon reveals is not the case in at least the Ghanaian environment. This preliminary investigation seems to suggest otherwise.
