Vertical restraints can have significant negative effects on competition.

Among the main effects, the exclusion of market access stands out, which can cause a reduction in competition by limiting or discouraging entry or participation in the market. Increased barriers to entry or expansion affect suppliers and buyers, and can force competitors to exit the market by forcing them to increase their costs. Vertical agreements can also cause a weakening of competition between different production chains as well as within a single one. Likewise, they can facilitate the use of collusive practices.[2]​.

These practices can affect social well-being, as they can lead to an increase in prices (for example, by causing increases in the marginal costs of their rivals), as well as restricting consumers' choice options, or increasing barriers to entry and expansion in the market.[1]​[5]​[6]​.

Vertical agreements can be positive when they help make production processes more efficient, or when they benefit consumers by reducing prices or improving the quality of goods or services. Likewise, they can help optimize investment levels and prevent possible price distortions.[1]​.

They can have positive effects on competition by combating the problem of “hold-up”, which occurs when one party to an agreement is left vulnerable to exploitation by the other after having made an investment that is difficult to recover if the business relationship ends. These restrictions can incentivize long-term investments and contracts that benefit both parties - improving efficiency, reducing the risk of failure of trade agreements, and benefiting consumers.[2]​.

In addition, they can address externalities resulting from agency conflicts of those who establish them or from conflicts arising from lack of coordination in pricing and sales decisions between suppliers and distributors. The externalities resulting from “free-riding” can also be mitigated with restrictions such as exclusive or selective distribution, which protect investments and encourage fairer competition.[2]​.

Finally, vertical constraints can reduce transaction costs (which are associated with logistics, administrative, negotiation, search and opportunistic behavior costs), prompting the supplier to lower its own costs and achieve economies of scale. This would benefit companies, as they would have lower costs and a higher sales volume, as well as consumers, who could take advantage of lower prices and greater availability of products in the market.[2]​.
