We present empirical measures of wealth inequality and its intergenerational transmission among four horticulturalist populations. Wealth is construed broadly as embodied somatic and neural capital, including body size, fertility and cultural knowledge, material capital such as land and household wealth, and relational capital in the form of coalitional support and field labor. Wealth inequalit...

The effect of wealth on consumption is an issue of longstanding interest to economists. Analysts believe that fluctuations in household wealth have driven major swings in economic activity. This paper considers so-called wealth effects—the impact of changes in wealth on household consumption and the overall macroeconomy. There is an extensive existing literature on wealth effects, but there are...

Figure 1 documents a strong negative relation in the United States between wealth (household net worth, from the Federal Reserve Flow of Funds, as a fraction of GDP) and aggregate volatility, measured as standard deviation of real GDP growth rate. Periods when net worth is high, reflecting high prices for housing and/or stocks, tend to be periods of low volatility in aggregate output, employmen...

Human lifespan in the developed world has been increasing continually for over a century, driven by steady medical advances coupled with, among other factors, improvements in diet and lifestyle on the back of rising prosperity. But this last part has a corollary: there must be some downward pressure on lifespan during times of declining prosperity. Indeed, some experts worry that mortality migh...

In this paper, we investigate the distribution and growth dynamic of individual producer’s aggregated attention wealth in crowd-sourcing phenomenon by mining data from digg. com. We observe that, the distribution of attention wealth deviates from power-law with a peak near the tail. We interpret the deviation with a stochastic model for attention wealth growth incorporating both promotion to fr...

Owing to the increasing population, the disparity of natural resources distribution and the variation of climate around the world, there are energy-water-food nexus problems in some countries in the world. It is the objective of the current work to point to the wealth of the oceans as a resource to find all three components. Aquaculture for deep water should also be investigated, and coastal aq...
