Our essay investigates if free trade results in economic growth for the developing countries. We have decided to investigate the least developed countries (LDC) in order to understand how they react with free trade. We have implemented a regression analysis with secondary data of a onetime period, it includes 10 years, 2004-2014. This essay will give us a better understanding for what the LDC countries require to grow and how they can integrate in a more active presence in the world economy and create better living standards for themselves. The analysis is about different factors that are crucial for free trade to result in economic growth. We have found that free trade does encourage the economic growth. There is significant result in the total regression analysis for free trade. We can forecast that investments and free trade interact with each other and the investment variable is also significant in some aspects. With a wider view in trade there will encourage the investments and acknowledge spillovers in both production efficiency like technology and structural improvements but also the human capital and the institutions can be considered as a fraction for the total possible development that is possible with free trade. Also demand and preferences is a part of this essay, when we discusses possible patterns when countries decide trading partners.
