Can America recover ideal rates of growth through interest-rate policies? This important analysis suggests that most economists misunderstand the issue. Updating Keynes, the analysis suggests that fiscal stimulus, labor union bargaining power, and more progressive income taxes are needed to support growth. (The article includes some algebra, which some readers may choose to skip.)
The main points of this paper are that loanable-funds macroeconomic models with their “natural” interest rate do not fit with modern institutions and data. Before getting into the numbers, it makes sense to describe the models and how to think about macroeconomics in the first place....Unfortunately, the article cited is behind a paywall. This is a useful short summary however.
