Compute a declining Safeguard baseline trajectory

Implements the 4.9% per-annum nominal decline in industry-average default baselines introduced by the 2023 reform. The formula is:

Usage

cer_safeguard_baseline_trajectory(industry, from_year = 2023, to_year = 2030)

Arguments

industry

Character scalar matching an industry value from cer_safeguard_industry_baselines().

from_year

Start year (default 2023 for FY 2023-24).

to_year

End year (default 2029 for FY 2029-30).

Value

A data frame with year, financial_year, baseline, and decline_factor columns.

Details

$$B_t = B_{2023\text{-}24} \times (1 - 0.049)^{t - 2023}$$

where t is the starting calendar year of the financial year. Default values are drawn from inst/extdata/safeguard_industry_baselines.csv.
