inflation_adjust_cost_data: Calculate annual inflation adjusted costs

In HealthEconomicsHackathon/inflatably: Inflating Costs to Present Value (PV) Using Different Source Rates

Description

Up to a present value (PV) inflated upwards.

Usage

inflation_adjust_cost_data(from_year, to_year, from_cost, inflation_df_nm)

Arguments

from_year	Date of cost to convert from
to_year	Date to convert cost to
from_cost	Cost at from_year
inflation_df_nm	Source of data (string) HCHS, or CPI.

Details

Option to use the following datasets:

• PSSRU annual inflation hospital and community health services (HCHS)

• CPI

(1 + i_{1})(1 + i_{2}) \cdots (1 + i_{n}) \times C

Clearly, for the same i each year this is simply

C(1 + i)^n

Value

Inflated (to) cost (scalar), with attributes used to generate the return value:

• from_year

• to_year

• from_cost

• reference Which inflation adjustment dataset used.

Examples

from_year <- 2012
to_year <- 2015
from_cost <- 96.140

1*(1+0.035)^6

inflation_adjust_cost_data(from_year = 2014,
                           to_year = 2016,
                           from_cost = 1,
                           inflation_df_nm = "HCHS")
1*1.004*1.01
