cost_table: Scheme cost profile

In DanBoyB/cba: A collection of tools for simple cost benefit analysis of simple road realignment schemes

Description

This function generates a table of costs broken down by type and year for input into a CBA

Usage

cost_table(cost_est, price_base_yr = 2011, opening_yr, appr_period = 30,
  disc_rate = 0.05, resid_period = 0, cpi_base = 99.4, cpi_cost_est,
  sppf = 1.3, spl = 1, labour_cont = 0.35, cost_yrs = c(2022:2025),
  cost_prop = c(0.116, 0.437, 0.409, 0.038))

Arguments

cost_est	The cost estimate for the scheme, entered in factor prices (millions)
price_base_yr	The price base year assumed for the appraisal. Defaults to 2011
opening_yr	The assumed opening year for the scheme
appr_period	The period in years over which the scheme is being appraised. Defaults to 30.
disc_rate	The test discount rate as a decimal.
resid_period	The period in years, after the appraisal period which is assumed to represent the residual value of the scheme. Defaults to 0.
cpi_base	The consumer price index for the price base year. Defaults tp 103.8 for 2011 (base Dec 2006)
cpi_cost_est	The consumer price index for the month and year of the scheme cost estimate
sppf	The shadow price of public funds. Defaults to 1.3
spl	The shadow price of labour. Defaults to 1.0
cost_yrs	The range of years over which the costs are assumed to be incurred
cost_prop	a vector list of the proportion of scheme costs for each year definec in the costYears argument.

Value

A table of scheme costs per year to be input into the cbaTable() function
