Geometric Gradient Problem:
The Saudis produce 3.65 Billion barrels of oil a year. Let’s ignore climate change and drone stuff and say that production will increase at 2% per year due to demand from Asia. Also, the current price of $65/barrel is expected to increase by 4 percent a year for 20 years. What is the present worth of the anticipated 20 years revenue stream assuming the interest rate is 8%.
Present value =
| $3,951.48 billion |
