This paper proposes a theory for the gradual evolution of knowledge diffusion and growth over the very long run. A feedback mechanism between capital accumulation and the ease of knowledge diffusion explains a long epoch of (quasi-) stasis and an epoch of high growth linked by a gradual economic...

This paper proposes a theory for the evolution of knowledge diffusion and growth over the very long run. A feedback mechanism between capital accumulation and knowledge spillovers creates a unified growth theory that explains a long epoch of (quasi-) stasis and an epoch of high growth linked by...

Changes in monetary policy and shifts in dynamics of the macroeconomy are typically described using empirical models that only include a limited amount of information. Examples of such models include time-varying vector autoregressions that are estimated using output growth, inflation and a...
