by Summary:
New paper on the empirical evidence of the relevance of the supermultiplier for explaining economic cycles by Ricardo Summa, Gabriel Petrini, and Lucas Teixeira. From the abstract:The demand-led supermultiplier growth model proposes that business investment is induced by income while autonomous expenditures determine economic growth. The most known versions of the model are presented at high levels of abstraction, focusing on general analytical properties and dynamic stability conditions. Based on those versions, Nikiforos et al. (2021) argue that the supermultiplier model cannot generate business cycles compatible with the empirical observation. In this paper, we show that this conclusion is a consequence of the misspecification of the variable chosen to represent the investment share,

New paper on the empirical evidence of the relevance of the supermultiplier for explaining economic cycles by Ricardo Summa, Gabriel Petrini, and Lucas Teixeira. From the abstract:
The demand-led supermultiplier growth model proposes that business investment is induced by income while autonomous expenditures determine economic growth. The most known versions of the model are presented at high levels of abstraction, focusing on general analytical properties and dynamic stability conditions. Based on those versions, Nikiforos et al. (2021) argue that the supermultiplier model cannot generate business cycles compatible with the empirical observation. In this paper, we show that this conclusion is a consequence of the misspecification of the variable chosen to represent the investment share, which includes business and residential investment. As the separation of those expenditures is a central point in the supermultiplier theory, we estimate a VAR model for the US economy (1967-2020) using only the data on business investment share instead. This procedure re-establishes an important feature to the supermultiplier theory, the mechanism of capital stock adjustment, as the empirical results points to the business investment share generally lagging the cycle. Finally, we make some remarks on how to discuss the business cycle from the supermultiplier perspective. We argue that for the supermultiplier, the business cycle depends less on the mechanism of capital stock adjustment than on the behavior of the autonomous components of demand and changes in the multiplier components. As the latter two are influenced by political, social and institutional factors, each business cycle has its own narrative.
