Endogenous Growth and Monetary Policy: How Do Interest-Rate Feedback Rules Shape Nominal and Real Transitional Dynamics?

Monetary authorities have followed interest-rate feedback rules in apparently different ways over time and across countries. The literature distinguishes, in particular, between active and passive monetary policies in this regard. We address the nominal and real transitional-dynamics implications of these different types of monetary policy, in the context of a monetary growth model of R&D and physical capital accumulation. In this setup, well-behaved transitional dynamics occurs under both active and passive monetary policies. We carry out our study from three perspectives: the convergence behaviour of catching-up economies; a structural monetary-policy shock (i.e., a change in the long-run inflation target); and real industrialpolicy shocks (i.e., a change in R&D subsidies or in manufacturing subsidies). We uncover a new channel through which institutional factors (the characteristics of the monetary-policy rule) influence the economies’ convergence behaviour and through which monetary authorities may leverage (transitional) growth triggered by structural shocks.
