A STRUCTURAL DECOMPOSITION OF REGIONAL ECONOMIC INSTABILITY: A CONCEPTUAL FRAMEWORK*
提出一个概念框架，利用投入产出模型将总产出方差分解为供给和需求来源，以识别区域经济不稳定的原因，为制定稳定政策提供依据。
ABSTRACT. Many rural regions are characterized by unstable economies. Studies that investigate economic instability in these regions, however, tend to examine the effects rather than causes of its occurrence. Efforts to diminish instability can only be successful if they address its sources. Using an input‐output model, a conceptual decomposition of the variance of gross output is used as a means of identifying supply and demand sources of instability. This framework can be used for empirical investigations into the causes of economic instability, and for the design of stabilization policies. Data limitations, however, may preclude some applications of the technique.
