Government bonds

The profit expected back on any project must be greater than that for projects having fewer risks. In 1974 some banks were offering certificates of deposit that returned a 7.5% profit per year. This investment and some Aaa bonds (see Table 10-12) or government bonds are probably minimum-risk situations. 

The tme merits of this equation are revealed by a survey of the leading terms governing bond dissociations when the cleavage occurs (1) in the interior of the molecule (i.e., when both K and L are polyatomic groups), (2) in its peripheral region [i.e., when K (or L) is an atom], or (3) when it concerns exterior bonds formed by a molecule, such as hydrogen bonds. These topics shall be discussed shortly.

The rules that govern bonds between atoms and molecules can be quite tricky. It may be worthwhile to review the chapters involving atomic structure and the periodic table/trends before you tackle the material presented here. 

Very conservative investments, such as government bonds, pay low returns in the range of 5 to 7 percent, but the risk involved is practically negligible. Preferred stocks yield returns of about 7 to 9 percent. There is some risk involved in preferred-stock investments since a business depression or catastrophe could cause reduction in returns or even a loss of the major portion of the capital investment. Common stocks may yield very high returns however, the returns fluctuate considerably with varying economic conditions, and there is always the possibility of losing much or all of the original investment. 

The opportunity cost of capital for pharmaceutical R D is higher than the interest rate on safe investments, such as insured bank deposits or government bonds, but just how high the cost of capital for pharmaceutical R D projects is depends on how investors evaluate the risks of these investments, (See appendix C for a detailed discussion of the cost of capital.) The risk and, therefore, the cost of capital varies across different projects and even within the same R D project at different stages of development. The cost of capital for any investment also varies from year to year with underlying changes in the risk-free rate of interest (e.g., on bank deposits). Thus, the full cost of R D varies widely over time and across projects. 

Central banks and market practitioners use interest rates prevailing in the government bond market to extract certain information, the most important of which is implied forward rates. These are an estimate of the market s expectations about the future directirMi of short-term interest rates. They are important because they signify the market s expectafirMis about the future path of interest rates however, they are also used in derivative pricing and to create synthetic bond prices from the extent of credit spreads of corporate bonds. 

Bonds that have part or all of their cash flows linked to an inflation index form an important segment of several government bond markets. In the United Kingdom, the first index-linked bonds were issued in 1981 and at the end of 2012 they accounted for approximately 25% of outstanding nominal value in the gilt market. Index-linked bonds were also introduced in the United States Treasury market but are more established in Australia, Canada,...

A common observation in government bond markets is that the longest dated bond trades expensive to the yield curve. It also exhibits other singular features that have been the subject of research, for example, by Pboa (1998), wbicb we review in this chapter. The main feature of long-bond yields is that they reflect a convexity effect. Analysts have attempted to explain the craivexity effects of long-bond yields in a number of ways. These are discussed first. We then consider the volatility and convexity bias that is observed in long-bond yields. 

From Figure 7.3, we see fliat to price a very Iraig-dated bond off the yield of the 30-year government bond would lead to errors. The unbiased expectations hypothesis suggests that 100-year bond yields are essentially identical to 30-year yields however, this is in fact incorrect. The theoretical 100-year yield in fact will be approximately 20-25 basis points lower. This reflects the convexity bias in longer dated yields. In our illustration, we used a hypothetical scenario where only three possible interest-rate states were permitted. Dybvig and Marshall showed that in a more realistic environment, with forward rates calculated using a Monte Carlo simulation, similar observations would result. Therefore, the observations have a practical relevance. 

In a conventional positive yield curve environment, it is common for the 30-year government bond to yield say 10-20 basis points above the tlO-year bond. This might indicate to investors that a 100-year bond should yield approximately 20-25 basis points more than the 30-year bond. Is this accurate As we noted in the previous section, such an assumption would not be theoretically valid. Marshall and Dybvig have shown that such a yield spread would indicate an undervaluation of the very long-dated bond and that should such yields be available an investor, unless he or she has extreme views on future interest rates, should hold the 100-year bond. 

Now let us imagine that the yield on a 100-year government bond with a coupon of 6.00% is 6.20%. This fits investor expectations that the very longdated bond should have a yield premium of approximately 20 basis points. This would set the price of the 100-year bond as ... 

The default spread in relation to the outright government bond yield... 

The yield of a benchmark government bond depends on expected inflation rate, currency rate, economic growth, monetary and fiscal policy. Conversely, the spread of a corporate bond is influenced by the credit risk of the issuer, taxation and market liquidity. Moreover, the yield spread depends on other factors such as ...
