The key stocks and flows of phosphorus (P) through food consumption in Beijing and Tianjin, two megacities in northern China, were explored using a material flow analysis (MFA) approach to construct a static model of P metabolism. A total of 4498 t P has accumulated with 72% of P flow imported through food consumption eventually remaining in Beijing in 2008. Around 64% of the total inflow of P ...

Correlations of stocks in time have been widely studied. Both the Random Matrix Theory approach and the graphical visualisation of so-called Minimum Spanning Trees show the clustering of stocks according to industrial sectors. Studying the correlation between stocks traded in markets of different countries we show that the Random Matrix Theory approach is able to separate stocks according to th...

This paper examines some cognitive biases of Vietnamese stock investors by analyzing trading records for 1,201 accounts at a brokerage firm. These investors tend to make poor trading decisions by selling good stocks and buying bad stocks.

We provide a formal treatment of both static and dynamic portfolio choice using the Disappointment Aversion preferences of Gul (1991), which imply asymmetric aversion to gains versus losses. Our dynamic formulation nests the standard CRRA asset allocation problem as a special case. Using realistic data generating processes, we find reasonable equity portfolio allocations for disappointment aver...

But the annual meeting of the Inter American Tropical...
