In this case, the single market is created if the UK is in EU. This is considered to be one of the hallmark achievements of EU. In the cases where the Union is created, the members of the union decide to eliminate the tariff among them. The effect of this tariff is that there will be lower priced imports. The consumers would increase the demand for the product owing to the lower prices. This process is known as a trade creation process. It is assumed that in this process, Denmark and UK will be benefited. The proponents of Brexit state that this would increase the aggregate demand for the milk and milk related products. This would lead to more business for Demark. However, in UK the people who are producers will be impacted. They state that the local producers will be impacted. In this process, it cannot be refuted in this paradigm that there will be a dynamic relation between the two nations. The market correction will enable in the growth of the industry and also sophistication in the consumer demands. UK can also free its other resources and focus on creation of different milk products. This would cause more resources to be freed for other innovation. This could lead to a comparative advantage where trade would continue as a positive aspect. This is the argument that is made by the proponents of the EU. They state that the creation of a single market would be beneficial for the European markets. This creation of the market would enable in the growth of EU markets.
