Recent empirical research has shown that income per capita in the aftermath of natural disasters is not necessarily lower than before the event. Income remains in many cases not significantly affected or, perhaps even more surprisingly, it responds positively to natural disasters. Here, we...

We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge exchange. Growth is generated through human capital accumulation and knowledge externalities. The available knowledge in any country depends on its connections to the rest of...

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...

Conventional R&D-based growth theory argues that productivity growth is driven by population growth but the data suggest that the erstwhile positive correlation between population and productivity turned negative during the 20th century. In order to resolve this problem we integrate R&D-based...

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 analyze the impact of increasing longevity on technological progress within an R&D-based endogenous growth framework and test the modelś implications on OECD data from 1960 to 2011. The central hypothesis derived in the theoretical part is that - by raising the incentives of households to...

Recent empirical research has shown that income per capita in the aftermath of natural disasters is not necessarily lower than before the event. In many cases, income is not significantly affected and surprisingly, can even respond positively to natural disasters. Here, we propose a simple...
