Abstract
After a year from the formal UK withdrawal from the EU, there are still different opinions about the potential economic impact of BREXIT. This paper gives detailed overview of the trade profile of UK and explores the determinants of United Kingdom`s export. We apply gravity model, to estimate the aggregate benefits of EU membership or reversed, lost benefits from leaving the EU. We measure the influence of GDP, distance, population, the EU membership, and signed free trade agreement with the trading partners on UK’s export as dependent variable. The analysis includes data for 70 UK trading partners in period of 70 years (from 1950 to 2020).
The results show that UK’s export is directly proportional to trade partner`s GDP and inversely proportional to distance. In order to estimate the average benefit due to EU membership, we estimated subsequent equations with different time periods. The coefficient decreases and becomes negative as we shorten the time periods, proving that the average trade advantage due to EU membership diminishes over time. According to economic theory of regional integration it is expected that the coefficient increases due to many rounds of enlargement, especially the biggest one in 2004 as well as due to the introduction of the Euro. On contrary, as we shorten the time periods in the analysis, we obtained increasing coefficient for the variable free trade agreements. This confirms that trade exchange within FTA has significantly higher effect on United Kingdom’s export in comparison with trade within EU.
