2) According to Raymond T Bye,( The Scope of Economics, Journal of Political Economy, 1939), there appear to be three methods by which economic phenomena may be investigated, and each of them has its vigorous champions. The first consists mainly in deductive analysis. Proceeding from a few simple premises based upon general observation to broad generalizations. The second is the historical method, which seeks an understanding of existing institutions by tracing their evolutions from their origins in the past. The third is statistical induction, which endeavours, by the analysis of numerical data, to develop quantitative knowledge of economic phenomena. Luckily, the disputes which have been waged between the advocates of these different types of analysis do not have to be settled before economics can be defined, for the question of definition is one of subject matter rather, than of method. Anyway, it is now coming to be recognized that these methods are
