This paper provides a critical view of macroprudential regulation/policies found in mainstream and post-Keynesian economics. The paper provides a macroeconomic framework that can be used as a basis for the analysis of macroprudential guidelines and policies. It is based on on five main principles/guidelines: (i) financial fragility is endogenous and results from the normal functioning of market based economies driven by the profit motive; (ii) financial fragility can originate in the financial and real sectors of an economy; (iii) financial cycles are not necessarily driven by boom and busts and financial fragility need not originate in an economic boom; (iv) macroprudential policies should be viewed from a dynamic perspective, that is they must take into account the changes in the international financial architecture/structure and be region/country specific; and (v) macroprudential regulation/guidelines requires a truly macroeconomic framework. These principles are captured in the specification of a baseline stock-flow model for Latin America and the Caribbean with five sectors (government, central bank, financial sector, private sector, and external sector). The model is a tool that can be used for evaluating other macroprudential policies.
