“Antitrust” Classes

Description

The “Antitrust” class is a building block used to create other classes in this package. As such, it is most likely to be useful for developers who wish to code their own calibration/simulation routines.

Let k denote the number of products produced by all firms below.

Slots

pricePre

A length k vector of simulated pre-merger prices.

pricePost

A length k vector of simulated post-merger prices.

output

A length 1 logical vector equal to TRUE if merger simulates the effect in an output market, and FALSE if the merger simulates the effect in an input market. Default is TRUE.

ownerPre

A k x k matrix of pre-merger ownership shares.

ownerPost

A k x k matrix of post-merger ownership shares.

labels

A length k vector of labels.

control.slopes

A list of optim control parameters passed to the calibration routine optimizer (typically the calcSlopes method).

control.equ

A list of BBsolve control parameters passed to the non-linear equation solver (typically the calcPrices method).

Objects from the Class

Objects can be created by calls of the form new("Antitrust", ...).

The “matrixOrList”, “matrixOrVector” and “characterOrList” Classes

The “matrixOrList”,“matrixOrVector” and “characterOrList” classes are virtual classes used for validity checking in the ‘ownerPre’ and ‘ownerPost’ slots of “Antitrust” and the ‘slopes’ slot in “Bertrand”.
