Presented is an evolutionary model of consumer non-durable markets, which is an extension of a previously published paper on consumer durables. The model suggests that the repurchase process is governed by preferential growth. Applying statistical methods it can be shown that in a competitive...

Conventional financial advice is that net present value (NPV) is a superior investment criterion to internal rate of return (IRR) because IRR has pitfalls. Despite the pitfalls, evidence shows most practitioners continue to employ IRR as an investment criterion. Such behavior is puzzling. This...

Two criteria for choosing between capital investment projects are net present value (NPV) and internal rate of return (IRR). Sometimes they provide inconsistent rankings. This inconsistency sparked a debate about which criterion is better. The debate has lasted more than 100 years.This paper...

Multiple interest rate analysis (MIRA) is the study of all interest rate solutions to the time value of money (TVM) equation. These solutions include not only the orthodox solution produced by a financial calculator or spreadsheet but also the unorthodox solutions that a typical financial...

The net present value (NPV) of an investment project having many potential outcomes can be expressed as a weighted average of the NPVs calculated from the individual outcomes, the weights being the outcome probabilities. Danielson (2016) demonstrates that this formula does not apply to the...

The time value of money (TVM) equation is a key equation in finance. It takes the form of an nth order polynomial having n roots. In finance it is normal to calculate and use only one root (interest rate). The remaining (n-1) roots are mostly complex or negative and they are usually discarded....
