Build CBS item prices

Source: R/prices.R
build_cbs_prices.Rd

Compute prices for all commodity balance sheet items, including processed products and crop residues. Prices are derived from trade data, with special handling for items without direct trade prices (palm kernels, soy hulls, brans, etc.). Crop residue prices are estimated as a fraction of the product price.

Usage

build_cbs_prices(
  cbs,
  trade_prices = NULL,
  residue_price_factor = 0.1,
  example = FALSE
)

Arguments

cbs

A tibble of commodity balance sheets, as returned by build_commodity_balances() or get_wide_cbs().

trade_prices

A tibble as returned by build_trade_prices(). If NULL, it is computed internally.

residue_price_factor

Numeric. Relative price of crop residues compared to the product. Default 0.1.

example

Logical. If TRUE, return a small example tibble. Default FALSE.

Value

A tibble with columns:

  • year: Integer year.

  • element: "import" or "export".

  • item_cbs_code: Numeric CBS item code.

  • price: Price in KDollars per tonne.

Examples
