The European Union (EU) has long been a proponent of policies that aim to promote economic growth. One of the most notable examples is the EU's single market, which was launched in 1993 and is often considered one of the EU's most successful policies. The single market allows for the free movement of goods, services, capital, and people within the EU. This has led to increased trade and investment, as well as greater competition and efficiency. The single market has also been a major driver of economic growth, with studies estimating that it has boosted GDP by 2-3% since its launch.

Another key policy area for promoting economic growth is the EU's competition policy. The EU has a strong competition regime that helps to ensure that markets are open and fair and that firms are able to compete on a level playing field. This helps to promote innovation and efficiency and can lead to lower prices for consumers.

The European Monetary Union is another key EU policy that has had a positive impact on economic growth. The EMU has helped to stabilize the economies of member states and has made it easier for them to trade with each other. The EMU has also made it easier for businesses to borrow money and has helped to reduce inflation.

The EU has also been a major force in liberalizing global trade. The EU is a member of the World Trade Organization (WTO), and has been instrumental in negotiating a number of free trade agreements (FTAs). These FTAs have helped to lower trade barriers and increase market access for EU firms.

The EU has also been active in promoting economic development in its member states. The EU provides financial and technical assistance to help member states modernize their economies and improve their competitiveness. The EU also helps to create an environment that is conducive to business investment and job creation.

Overall, the EU's policies have had a positive impact on economic growth. The Single Market and the European Monetary Union have made it easier for businesses to trade and expand their operations. These policies have also made it easier for people to find work and travel within the EU. All of these policies have helped to boost economic growth in the EU. In the last few years, the EU has been growing faster than the US and Japan and is now the second largest economy in the world. The EU's policies on promoting economic growth are therefore having a positive impact on the global economy.
