The yield curve is usually upward sloping. Assess whether this means that the following statements are true or false:
1. Investors earn a higher annualized rate of return from long-term T-bonds than short-term T-bills.
2. Long-term T-bonds are better investments than short term T-bills.
3. Investors are expecting higher inflation in the future than they are today.
4. Investors who are willing to take the risk of investing in long-term bonds on average earn a higher rate of return because they are taking more risk (that in the interim bond prices fall / interest rates rise)
