From any object created by either fareprim
, fisher
,
hicksmoorsteen
, laspeyres
, lowe
, or paasche
function, and provided that the argument shadow
(or components
in the case of hicksmoorsteen
)
is set to TRUE
in the function's call, this function extracts the deflated cost input and revenue output
shadow prices.

Shadow prices are derived from dual input- and output-oriented DEA models.
In the case of Fisher, Hicks-Moorsteen, Laspeyres, Lowe and Paasche indices, deflated input and output shadow
prices for each observation are returned (if the argument shadow = TRUE
in the function's call).
In the case of Hicks-Moorsteen index, shadow prices used to compute Malmquist-hs and Malmquist-it
for each observation are returned (if the argument components = TRUE
in the function's call).
In the case of F<c3><a4>re-Primont index, the deflated input and output shadow prices of the representative observation
(i.e. the sample means of quantities and prices) are returned (if the argument shadow = TRUE
in the function's call).
An object of class 'FarePrimont'
is a result of a call to fareprim
.
An object of class 'Fisher'
is a result of a call to fisher
.
An object of class 'HicksMoorsteen'
is a result of a call to hicksmoorsteen
.
An object of class 'Laspeyres'
is a result of a call to laspeyres
.
An object of class 'Lowe'
is a result of a call to lowe
.
An object of class 'Paasche'
is a result of a call to paasche
.
In the case of F<c3><a4>re-Primont, Fisher, Laspeyres, Lowe and Paasche indices, the function returns
a data frame containing all the elements and observations included in the "Shadowp"
component of object
.
In the case of Hicks-Moorsteen index, the function returns a list of two data frames containing, for each observation, input and output deflated shadow prices related to Malmquist-hs and Malmquist-it indices (and therefore not Hicks-Moorsteen shadow prices per se).
*
MalmquistHS:A data frame containing, for each observation, input and output shadow prices of the Malmquist-hs index.
*
MalmquistIT:A data frame containing, for each observation, input and output shadow prices of the Malmquist-it index.
For extreme efficient observations, the problem of multiple solutions may arise and the values of shadow prices may differ depending on the linear programming solver used (here lpSolveAPI).
