snqProfitShadowPrices: Shadow Prices of a SNQ Profit function

Description

Calculates the shadow prices of a Symmetric Normalized Quadratic (SNQ) profit function.

Usage

snqProfitShadowPrices( priceNames, fixNames, estResult = NULL,
   data = estResult$data, weights = estResult$weights,
   scalingFactors = estResult$scalingFactors,
   coef = estResult$coef, form = estResult$form )

Arguments

priceNames

a vector of strings containing the names of netput prices.

fixNames

an optional vector of strings containing the names of the quantities of (quasi-)fix inputs.

estResult

object returned by snqProfitEst.

data

a data frame containing the data.

weights

vector of weights of prices used for normalization.

scalingFactors

factors to scale prices (see details).

coef

a list containing the coefficients (at least delta and gamma).

form

the functional form to be estimated (see details).

Examples
