This paper aims to advance the debate on Multi-sectoral Thirlwall's Law, including sectorial capital flows and its implications for the new Brazilian economy's growth strategy, which aims to stimulate exports through diversification of products, the aggregation value and increased technology intensity of Brazilian exports. To this end, it develops a multi-sectoral model with sectorial capital flows and, as a result, are carried out some computer simulations considering the main sectors and economic partners of the country (China, United States and the Euro Block). The results suggest that the best strategy is to encourage specific sectors, that is, increase the participation of the sectors that the country has comparative advantage in relation to each of its trading partners (Manufactured - US , Semi-manufatured - Europe, Primary - China). Despite the results obtained in the simulation, the model templates proposed by Hausmann et al. (2004), can generate the acceleration of economic growth. Thus, the National Plan for Exports (2015-2018) should give preference to the expansion of incentives to sectors that have high ratios of elasticity in the sense of Thirlwall. [ABSTRACT FROM AUTHOR]

This paper aims to present the recent debate about Sraffian Supermultiplier Model (SSM), that gained notoriety in the academic environment after the controversy between Peter Skott (2016) and Marc Lavoie (2016, 2017) on the specification of the investment function of the Neo-Kaleckian models of income growth and distribution. Lavoie used the SSM model as an attempt to rescue the Neo-Kaleckians models of the devastating criticism made by Peter Skott (2010) regarding the specification of the investment function. In this context, we will not only argue that this rescue operation was not successful, but we will also question the capacity of SSM models to serve as an "alternative closure" for heterodox models of income growth and distribution, due to three fundamental shortcomings of the SSM approach, which are: (i) the hypothesis that the normal degree of utilization of the productive capacity is an exogenous variable, (ii) that investment in capacity expansion is totally endogenous; and (iii) the applicability of this approach out of a closed economy framework. We will also argue that the Kaldorian models of growth, which are one of the theoretical foundations of the so-called Developmentalist Macroeconomics, and stock-flow consistent models (SFC) seem to be much more promising alternatives for the development of heterodox theories of growth and income distribution.
