Internal rate of return IRR is one of the key criteria for justifying and choosing capital investments with conventional cash flows. However, this criterion is not practically used when the rate of return of investment instruments (short sales, options, futures, swaps) is calculated because these instruments create non-conventional cash flows. The author previously showed that IRR problems were observed when the present value of cash flows changed sign from period to period. This paper offers a criterion to evaluate the rate of return of investment instruments with non-conventional cash flows, i.e. General Rate of Return (GRR).
The author considers the conflict between NPV and IRR criteria in investment projects with non-conventional cash flows. This paper presents a new measure - the generalized net present value (GNPV) - to eliminate the disadvantages of the NPV in investment projects with non-conventional cash flows. The GNPV is a monotonically decreasing function of the discount rate with a single root - the GIRR, i.e. the rate of return of investment projects with non-conventional cash flows. The author formulates the GNPV and GIRR rule for investment justification and ranking, offers a criterion to differentiate between investment projects with non-conventional and conventional cash flows.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
