This is some fascinating stuff!

From the conclusion:

This first Econ Dev Blog (EDB) has given a descriptive overview of the major trends for the market of minerals in EVE. Overall trade quantity and volume has increased dramatically over the last 3 years and the price of minerals has fallen considerably due to increased mining efficiency through better tactics and improved technology. The price formation has also improved showing that price difference between regions is becoming minimal in Empire space and reflects only the time value of moving minerals in low sec. However, smaller population and the risk of piracy in zero-zero space results in less efficient markets with low volumes and great fluctuations in prices given an arbitrage trade opportunity for the brave entrepreneur.
