The historical crusades against Muslim lands, the colonization of Spain by the Muslim Moors and India by the British were all driven by economic interests, despite the advertised reasons that were used to mobilize their armies at the time. In my opinion, the invasion of Iraq was not about spreading democracy or weapons of mass destruction, it was about the oil.

Equity risk premium refers to the excess return that investing in the stock market provides over a risk-free rate. This excess return compensates investors for taking on the relatively higher risk of equity investing. The size of the premium varies depending on the level of risk in a particular portfolio and also changes over time as market risk fluctuates. As a rule, high-risk investments are compensated with a higher premium.
