The Poverty of Linear Nations: Lessons from Taking an AK Model to the Data

Abstract: This paper takes an AK model to the PWT data. In the model, intratemporal and intertemporal shocks are reduced forms for different technologies, and determine the variation of the growth rate. Using the policy functions of the model we recover time series for the unobserved technology shock for a panel of countries. We can then evaluate both how well the model fits the data and what the contribution of the different shocks to the variation of growth rates is. We find that the data is largely inconsistent with the AK structure. However, we isolate what we believe are pervasive patterns in macroeconomic models: a negative correlation between intra and intertemporal shocks, and an ever increasing level of technology matched with ever cheaper consumption relative to investment.
