We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge exchange. Knowledge in any country depends on the human capital of the countries it exchanges knowledge with. The diffusion of knowledge throughout the world explains a period...

This article investigates economic performance when enforceable property rights are missing and subsistence needs matter. It shows that if per capita income is sufficiently high, a windfall gain in productivity triggers behavior that leads to higher growth (the normal reaction). The same shock...

This paper presents the long-run equilibrium and development dynamics in the neoclassical growth model and a simple model of endogenous growth when property rights are absent. The results are compared to the outcome in a corresponding model with secure property rights. The main findings are that...

We generalize the result of Alesina and Rodrik (1994) by showing that their static solution is also a time consistent Stackelberg solution of a differential game between the government and the median voter

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...

We set up a simple overlapping generation model that allows us to distinguish between life expectancy and active life expectancy. We show that individuals optimally adjust to a longer active life by educating more and, if the labor supply elasticity is high enough, by supplying less labor. When...

For most of human history there existed a well-educated and innovative elite whereas mass education, market R&D, and high growth are phenomena of the modern period. In order to explain these phenomena we propose an innovation-driven growth model for the very long run in which the...

This paper introduces the Small World model (Watts and Strogatz, Nature, 1998) into the theory of economic growth and investigates how increasing economic integration affects firm size and efficiency, norm enforcement, and aggregate economic performance. When economic integration is low and...
