Tacit Agreements Collusion

If price leadership is adopted to facilitate tacit (or tacit) collusion, the price leader will usually tend to set a price so high that the least profitable firm on the market can achieve a return above the competitive level. Companies that market to consumers that they are “never knowingly undersold or that claim to monitor and achieve the cheapest price in a particular geographic area are involved in tacit agreements. In 2014, EDF was one of six major energy companies under investigation by the UK Competition and Markets Authority to determine whether consumers are being treated unfairly due to coordinated price increases (i.e. tacit collusion). While this collusive arrangement isn`t a balance in the one-shot game above, the repetition of the game allows companies to maintain collusion over long periods of time. This can be achieved, for example, if each company`s strategy is to deliver normal advertising as long as its rival does the same, and to pursue aggressive advertising forever once its rival has used an aggressive advertising campaign at least once (see: sinister trigger) (this threat is credible because the symmetrical use of aggressive advertising is a Nash equilibrium of each stage of the game). Each company must then weigh the short-term gain of $30 from the “fraud” against the long-term loss of $35 in all future periods, which is part of its punishment. Provided companies care enough about the future, the deal is a balance of this repeated game. Companies therefore prefer not to cheat (so collusion is a balance) when tacit collusion occurs when companies choose actions that can minimize a reaction from another company.B, for example by avoiding the possibility of reducing a call, as this would prompt the opposition to retaliate. In other words, two companies agree to pursue a specific strategy without explicitly saying so. Oligopolists usually try not to engage in price reductions, excessive advertising or other forms of competition. Thus, there may be unwritten rules for collusive behavior such as price leadership (tacit collusion). A price leader will then emerge and set the overall price of the industry, with other companies to follow.

See, for example, the case of British Salt Limited and New Cheshire Salt Works Limited. [1] Tacit collusion is best understood in the context of a duopoly and the concept of game theory (i.e. Nash equilibrium). Let`s take the example of two companies A and B, both of which play a promotional game over an indefinite number of periods (in fact “infinitely numerous”). The payments of both companies depend on their own measures, but above all on the action of their competitor. They can choose to stay at the current advertising level or choose a more aggressive advertising strategy. If one of the companies opts for low advertising while the other opts for high advertising, the low-advertising company suffers a sharp loss of market share, while the other receives a boost. However, if both opt for high advertising, the market share of both companies will increase, but their advertising costs will increase, thereby reducing their profits. If both choose to stay at the normal advertising level, sales will remain constant without the additional advertising costs. Therefore, both companies will suffer a larger payout if they both choose regular advertising (however, this set of promotions is unstable as both are tempted to spill over into higher advertising to increase payouts).

A payment matrix is represented by numerical numbers: classical economic theory states that Pareto efficiency is achieved at a price equal to the incremental cost of producing additional units. Monopolies are able to generate optimal revenues by offering fewer units at a higher cost. An oligopoly in which each company acts independently tends to balance ideally, but secret cooperation such as price leadership tends to lead to higher profitability for all, even if it is an unstable agreement. To be more specific, suppose companies have a discount factor δ {displaystyle delta }. The present value of the cost of fraud and punishment indefinitely, we see examples at mortgage lenders and gas retailers, where many providers follow the pricing strategies of large corporations. While most firms move prices in the same direction, it may take some time for relative price differences to occur, which can cause consumers to change their demand. In companies` leadership in barometric pricing, the most reliable company turns out to be the best barometer of market conditions, or the company could be the company with the lowest production costs, prompting other companies to do the same. Although this company does not dominate the industry, its prices are supposed to reflect the most satisfactory market conditions, as the company would most likely be a good forecaster of economic changes. .
