This article takes a fresh look at reswitching. When two production techniques are compared, reswitching occurs when one technique is more viable than the other at a high interest rate, switches to being less viable at a lower rate, and reswitches to being more viable again at even lower rates....

In fixed income analysis it is known that the various measures of interest rate sensitivity (duration) yield approximate results. Even with the addition of concepts like convexity, the results remain approximations. This paper summarizes a new approach based on the fact that the time value of...

It is well known that the various formulas for the duration of a bond give inaccurate results. Their accuracy can be improved by the addition of extra elements, such as convexity or duration vectors. But the results remain inaccurate. A recent paper proposed a new formula for the duration of a...

There is an apparent rift between the way banks calculate and the way humans think.On the one hand, exponential discounting has played a centuries-long, lead role in financial analysis. On the other hand, experiments by behavioral economists demonstrate that hyperbolic discounting is better than...

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...
