Economics can be likened to a car’s engine. The course constitutes a set of distinct but interrelated parts that are systematically connected as one. This allows for the effective functioning of the different branches of the discipline. The various branches of the discipline are synchronized as an integrated whole. The whole, however, is each part that is properly functioning. The discipline is subdivided into micro and macroeconomics. Moreover, within each subdivision, there are many other branches of the course. Economics set out to explain and offer solutions to many of society’s concerns. Those concerns are explained by way of modeling. A good model is a properly functioning engine. The engine assembles a radiator, a battery, a coberator, and other parts into an integrated whole. The entire block of components is the engine; that is systematical connected to constitute a final part. Economics is the same as an engine. Without the problem statement, the hypotheses (i.e. the assumptions), past literature, the collected data, the technique of statistical inference and the mathematical equation (i.e. the model), there is no economics.
Economics is not just mathematical formulae: But the discipline is series of steps that are merged by way of a flow chart. After the mechanical steps come the mathematical formulae. A mathematical formula is unlike to be valid without having past through the steps previously mentioned. Furthermore, any aspect to the model that is not followed destroys the pattern. The course becomes a useless set of jargons without validity and predictability, if the practitioner overlooks a step. The pattern is a puzzle. Without an item to complete the whole, the pattern fails to provide that unified taste like that of a hamburger. Hence, Economics is indeed an engine. It is a pattern. Of the many components that are joined together by way of a model- a mathematical formula, economics is science. All the apparatus of the model irrespective of it order in the sequence cannot be forgone as it directly influence the next stage in the process. Economics is a sequence of interrelated events that are structure in a concise, comprehensive, organic and mechanical manner.
