Growth theory is based on the assumption of exponential total factor productivity (TFP) growth. Across countries and time periods I find that TFP growth is actually linear. Unlike the exponential model, the additive growth model provides useful medium-term forecasts of TFP. It also explains the...

We propose a Unified Growth model that analyzes the role of the Scienti fic Revolution in the takeoff to sustained modern economic growth. Basic scientific knowledge is a necessary input in the production of applied knowledge, which, in turn, fuels productivity growth and leads to rising...

Education, general health, and reproductive health are key indicators of human development. Investments in these domains can also promote economic growth. This paper argues for the importance of human development related investments based on i) a theoretical economic growth model with poverty...

We analyze the long-run growth effects of automation in the standard overlap- ping generations framework. We show that, in contrast to other neoclassical models of capital accumulation, automation does not promote growth but induces economic stagnation. The reason is that automation suppresses...

Growth accounting breaks down economic growth into components associated with changes in factor inputs and the Solow residual, which reflects technological progress and other elements. This exercise is generally viewed as a preliminary step for the analysis of fundamental determinants of growth...
