In this paper, we develop the idea of the Sraffian Supermultiplier, presenting it as an alternative to traditional neoclassical thought about economic growth and economic policy. Thus, a brief introduction is made about the importance of economic growth for classical economists, followed by the development of Harrod's model and the different solutions that have raised for sorting the problem of instability. Finally, we present the supermultiplier model of Serrano together with international empirical evidence that supports it and some proposals of economic policy are made. [ABSTRACT FROM AUTHOR]

This paper presents evidence that macroeconomic accounting models helped to anticipate the credit crisis and economic recession, whereas equilibrium models, ubiquitous in mainstream policy and research, did not. This study traces the intellectual pedigree of the accounting approach as an alternative to neo-classical economics, and the postwar rise and decline of flow-of-funds models in policy use. The paper includes contemporary case studies of both types of models, and considers why the accounting approach has remained outside mainstream economics. Finally, it provides constructive recommendations for revising financial stability evaluation methods, and advocates an 'accounting of economics'. [ABSTRACT FROM AUTHOR]
