- Creating Multiple Instances of Correlations – In this video we show how you can create multiple instances of correlated random variables. For example, the percentage change in the price of each of 4 stocks on day N may be correlated, but none of the day N percentages are correlated with any other day.

- Introduction To Supply Contracts – In this video we introduce a simple supply chain where coats are manufactured in Asia for a US retailer.
- Buyback Contracts – In this video we show that when the manufacturer is willing to buy back leftover coats both the retailer and manufacturer benefit.
- Revenue Sharing Contracts – In this video we show that if the retailer shares some revenue with the manufacturer and the manufacturer reduces the wholesale price, then the performance of the supply chain improves.
