Antitrust LawsAntitrust Laws

Antitrust laws are an outgrowth of the early Antitrust laws are an outgrowth of the early years of the Industrial Age in the United years of the Industrial Age in the United States when a small number of powerful States when a small number of powerful businessmen used any tactic at their disposal businessmen used any tactic at their disposal to force competitors out of business. Because to force competitors out of business. Because such business practices were not in the best such business practices were not in the best interest of the country, federal legislation was interest of the country, federal legislation was passed that prohibits the formation and passed that prohibits the formation and continuation of monopolies except when in continuation of monopolies except when in the best interest of the public.the best interest of the public.

A negative (-) (moving in the same direction). A negative (-) bb value value indicates that the dependent and the independent variables indicates that the dependent and the independent variables are moving in opposite directions.

Reasons for the UnexpectedReasons for the Unexpected

Some of the accounting reasons that regressions may yield unexpected or perplexing results include:– When and how allocations are made.– The nature of transfer prices in an organization.– Entity concept: what part of the business is

involved in the case?– Accounting policies can make a big difference

in cost behavior analysis.Forensic accountants must be adequately informed about the nature and operation of the accounting system for each and every business that they are evaluating.
