Usage
rescale_discount_rate(x, from, to)
Arguments

Discount rate to rescale. |

Original time period. |

Details
Continuous discounting is assumed, i.e. when converting a long-term discount rate into a short-term rate, we assume that a partial gain from one short term is multiplicatively discounted in all following short terms. At the same time, we assume the short-term rate is time-invariant.
Value
Rate rescaled under the assumption of compound discounting.
Examples
## 1% monthly interest rate to annual
rescale_discount_rate(0.01, 1, 12)
## 3% annual discount rate to (approximately) weekly
rescale_discount_rate(0.03, 52, 1)
