| Abstract: | We employ a novel approach for analyzing the effects of relative consumption and relative wealth preferences on both the decentralized and the socially optimal economic growth rates. In the pertinent literature these effects are usually assessed by examining the dependence of the growth rates on the two parameters of the instantaneous utility function that seem to measure the strength of the relative consumption and the relative wealth motive. We go beyond the sole consideration of parameters by revealing the fundamental factors that ultimately determine long-run growth. In doing so we identify widely used types of status preferences in which the traditional approach is prone to erroneous conclusions. For example, in one of these specifications the parameter that seems to determine the strength of the relative consumption motive actually also affects the strength of the relative wealth motive and the elasticity of intertemporal substitution. |

| Abstract: | This paper describes the emergence of complexity as duplicated evolutionary process. The first procedural source of complexity is the quantum jump of the evolution of the human species when it started to maintain certain brain-internal models of its environment. The second - parallel - procedural origin is the evolution of a communication structure, a language, with which an already existing group of primates could frame their internal models. In contrast to definitions of complexity which use the concept in the context of theoretical physics, this approach reveals some perplexing properties of model-building for a special subject of investigation; namely the human species: All adequate models of political economy (economics is just the sub-discipline that freezes political dynamics) have to be complex. Since today’s mainstream economic theory lends its formal apparatus from the mathematics of Newtonian physics, it misses the most essential features characterizing human social dynamics, i.e. its complexity. |

| Abstract: | Scholars have conjectured that the return to speaking a language increases with the number of speakers. Long-run economic and political integration would accentuate this advantage, increasing the population share of the largest languages. I show that, to the contrary, language size and growth are uncorrelated except for very small languages (<35,000 speakers). I develop a model of local language coordination over a network. The steady-state distribution of language sizes follows a power law and precisely fits the empirical size distribution of languages with ≥35,000 speakers. Simulations suggest the extinction of 40% of languages with <35,000 speakers within 100 years. |

| Abstract: | In many models, economic growth is driven by people discovering new ideas. These models typically assume either a constant or a growing population. However, in high income countries today, fertility is already below its replacement rate: women are having fewer than two children on average. It is a distinct possibility — highlighted in the recent book, “Empty Planet” — that global population will decline rather than stabilize in the long run. What happens to economic growth when population growth turns negative? |
