Level playing field


In commerce, a level playing field is a concept about fairness, not that each player has an equal chance to succeed, but that they all play by the same set of rules.
In a game played on a playing field, such as rugby, one team would have an unfair advantage if the field had a slope. Since some real-life playing fields do in fact have slopes, it is customary for teams to swap ends of the playing field at half time.
A metaphorical playing field is said to be :wikt:level|level if no external interference affects the ability of the players to compete fairly.
Some government regulations are intended to provide such fairness, since all participants must abide by the same rules. However, they can have the opposite effect, for example if larger firms find it easier to pay for fixed costs of regulation. It may be added that if the rules affect different participants differently, then they are not actually the same.
Handicapping might be thought of as the opposite concept, of unequal rules designed to make the outcome of play more equal.

Examples

Governments, regulators and sports associations may try to create a 'level playing field'.
Examples of such regulation: building codes, material specifications and zoning restrictions, which create a starting point / a minimum standard --- a "level playing field".

What is meant to "level the playing field" can be subjective, for example when a regulation does not change the probability distribution of outcomes. For example, the fact that all companies are required to pay the same rate of corporate income tax could be described as "creating a level playing field", while some may say that this does not level the playing field, because while the requirements are equal for all companies, larger companies may have more resources from which to pay the tax.
