Modern study of currency policy primarily follow two patterns: the pattern of “Data are everything by themselves” or that of “deductive analysis based on a rigorous theory”. The former is characteristic of the mode of vector regression while the latter is typical of the mode of general balance of dynamic RAM. The two patterns were both derived from structural analysis, so prove not to be efficient enough in theoretical rigorousness, introduction of rational expectation and estimating means by parameters, and imitating, predicting and decisionmaking functions. As a result, the DSGEVAR mode as a typical modern pattern of currency policy study offers a most balancing means for development by realizing an effective combination of theoretical deduction with measuring technology.
