Get GDP and GDP per capita scenarios

Like all scenarios in mrdrivers, the GDP and GDP per capita scenarios are the result of a harmonization exercise between past data and future projections. Together with the corresponding population scenarios (see calcPopulation()) they comprise a consistent set of scenarios.

By default the following scenarios are returned:

• the SSPs, i.e. SSP1-5

• the SDPs, i.e. SDP, SDP_EI, SDP_RC, and SDP_MC

• SSP2EU

See the vignette: vignette("scenarios") for scenario options, definitions and references.

Usage

calcGDP(
  scenario = c("SSPs", "SDPs", "SSP2EU"),
  unit = "constant 2005 Int$PPP",
  average2020 = TRUE,
  ...
)

calcGDPpc(
  scenario = c("SSPs", "SDPs", "SSP2EU"),
  unit = "constant 2005 Int$PPP",
  average2020 = TRUE,
  ...
)

Arguments

scenario

A string (or vector of strings) designating the scenario(s) to be returned. Use toolGetScenarioDefinition() to learn what scenarios are available.

unit

A string specifying the unit of GDP. Can be either:

• "constant 2005 Int$PPP" (default): Scenarios are constructed in constant 2005 Int$PPP.

• "constant 2005 US$MER": Scenarios are constructed in constant 2005 Int$PPP and then converted with GDPuc::convertGDP().

• "constant 2017 Int$PPP": Scenarios are constructed in constant 2017 Int$PPP.

• "constant 2017 US$MER": Scenarios are constructed in constant 2017 Int$PPP and then converted with GDPuc::convertGDP().

In all cases, GDP is returned in millions.

average2020

If TRUE (default), then the 2020 value is replaced by the 2018-2022 average. To be consistent, the yearly resolution is decreased to 5 year intervals.

...

Arguments passed on to calcDriver(), of which "extension2150" and "naming" are most often of interest. Other calcDriver() arguments are used for scenario fine-tuning and by package developers.

Value

magpie object with the requested output data either on country or on regional level depending on the choice of argument "aggregate" or a list of information if supplementary is set to TRUE.

Examples

if (FALSE) {
# Return default scenarios
calcOutput("GDP")
calcOutput("GDPpc")

# Return only the SSP2EU GDP scenario
calcOutput("GDP", scenario = "SSP2EU")

# Return the now-outdated GDP scenarios used before summer 2021,
calcOutput("GDP", scenario = "SSPsOld", extension2150 = "constant", average2020 = FALSE)
}

if (FALSE) {
calcOutput("GDPpc")
}
