Resumen
The European Union project is strongly challenged today by the historical decision of United Kingdom?s citizens to exit from this structure, with all consequences assumed. United Kingdom will be the first nation that will quit this ambitious initiative and the decision is transmitted by the organized national referendum?s results in this respect. The population?s opinion expressed by a huge number of voting persons should be taken into consideration by British politicians and transposed very soon into political actions that could have a strong and clear economic impact on both sides. This paper will discuss the possible economic consequences of such historical decision, including potential effects on a small country like Romania.
