To elaborate, by starting with data from only a single experiment (reference data) for the reaction in question (e.g. 43% yield in 3 h at 78 °C), the developed software could estimate the time expected to give any specified yield, between 5 and 95%, for that reaction at the same temperature. Alternatively, different conditions of time (between 0.1 and 10 min) and temperature (between 0 and 270 °C) that would be expected to return any nominated yield or conversion between 5 and 95% could be calculated. Starting with the aforementioned set of reference data for the subject reaction (43% yield in 3 h at 78 °C), it could be estimated, for exam-...

Therefore, the break-even analysis allows to determine the spread that equals the price of a conventional bond to the one of an inflation-linked bond. This approach assumes a risk-neutral pricing by which an investor treats conventional and inflation-linked bonds the same. Under break-even hypothesis, both bonds have the same nominal yield. Note if the inflation breakeven is greater than expected inflation, for an investor is favorable to buy a conventional bond. Conversely, the inflation-linked bond is more attractive. If inflation breakeven and expectations are equal, the investor bond s choice will be then indifferent. Figure 6.2 shows the trend of UKGGBEIO and UKGGBE20 Index... 

In the traditional approach the duration value is calculated using nominal cash flows, discounted at the nominal yield. A more common approach is to assume a constant average rate of inflation, and adjust cash flows using this inflation rate. The real yield is then used to discount the assumed future cash... 

A repeat of the above procedure, with the additional step, after the shift in the yield curve, of recalculating the bond cash flows based on a new inflation forecast. This produces a duration measure that is a function of the level of nominal yields. This measure is in effect an inflation duration, or the sensitivity to changes in market inflation expectations, which is a different measure to the real yield duration ... 

An assumption that the inflation scenario will change by an amount based on the historical relationship between nominal yields and the market expectation of inflation. This is in effect a calculation of nominal yield duratimi, and would be a measure of sensitivity to changes in nominal yields. 

In essence, the real yield curve can and should be used for all the purposes for which the nominal yield curve is used. Provided that there are enough liquid index-linked bonds in the market, the real term stmcture can be estimated using standard models, and the result is more valid as a measure of market inflation expectations than any of the other methods that have been used in the past. 

We have already described the notion of bond trading in three dimensions, thanks to the availability of linkers. Perhaps the most important aspect of this 3D trading is the ability to implement a view with much greater precision. Often, when trades are done in nominals, they really reflect a view on inflation, bnt because nominal yields do not just represent inflationary expectations, this is an imprecise enactment of that view. With inflation-linked bonds, investors can express a much purer inflation expectation. 

Applying the indexation lag, this allows us to calculate estimated nominal values of all future cash flows which, knowing the current dirty nominal price, P, allows us to solve for an internal (nominal) rate of return—a nominal, semi-annual, gross redemption yield, y. Having applied our 3% inflation assumption, /, to get nominal future payments, we now remove it from the nominal yield using the simple formula... 

So we have formally introduced the notion of break-even inflation, a term at the heart of inflation-linked bond analysis and trading. In principle it is the rate of inflation that will equate the returns on an inflation-linked bond and a comparator nominal bond issue of the same term. In theory, calculating it by simply subtracting a real yield from a nominal yield is a crude form of a properly compounded calculation, particularly when bond market conventions are semi-annual and what you should want is an annual measure of inflation. 

How does an investor measure the modified duration of linkers It sounds like a straightforward question and there is an easy answer, but it is sadly not the answer that people generally want. The easy answer is that a linker s modified duration is the (normalised) first derivative of price with respect to real yield, just as a conventional bond s modified duration is that with respect to nominal yield. This answer is a flippant one, because what people really want to know is some empirical rule about the sensitivity of a linker s price with respect to nominal yields, either for hedging purposes or in order to calculate aggregate duration statistics for portfolios holding both nominal and real bonds.

By way of example, consider the first US inflation-linked issue, maturing January 2007, where the early experience was of rising real yields while nominal yields fell. Much depends on the time horizon used, and this just shows how unreliable these betas can be. Already, the European linker market has experienced betas well below 1, above 1, and negative.

What the formula tells us is that, theoretically, the variance of nominal yields could actually be lower than that for linker real yields if real yields and inflationary expectations were sufficiently highly negatively correlated, i.e., the beta could exceed one. We d place heavy emphasis on the word theoretically, and we mention it only because Wesley Phoa entertains the possibility in his book. He cites analysis suggesting that there is a long-term negative correlation between GDP and inflation, then (reasonably) argues that real yields are a function of real GDP, hence real yields and break-evens should be inversely related.

A noteworthy fact is that fixed-income portfolios in times of economic prosperity in the United States, like at the beginning and mid-1980s, achieved impressive results. Note that all return figures displayed in this chapter are nominal values and apply for the US dollar area. In particular the beginning 1980s were characterized by high inflation rates and nominal yields. In the course of the 1990s, inflation and nominal rates dropped. 

The material used was 3003-0 aluminum alloy, 3.18 mm (0.125 in.) thick, cut into compact tension specimens as in Trebules s work [% Also, 5.6-mm (0.22-in.)-thick specimens prepared from material removed from a brazed heat exchange cap sheet were tested. The nominal yield strength and ultimate strength of 3003-0 aluminum are 41 MPa (6 ksi) and 110 MPa (16 ksi), respectively. 

Duration increases as coupon and yield decrease. The lower the coupon, the greater the relative weight of the cash flows received on the maturity date, and this causes duration to rise. T ong the non—plain vanilla types of bonds are some whose coupon rate varies according to an index, usually the consumer price index. Index-linked bonds generally have much lower coupons than vanilla bonds with similar maturities. This is true because they are inflation-protected, causing the real yield required to be lower than the nominal yield, but their durations tend to be higher.
