That tells you exactly nothing about what difference you would have got had we not left the union. The articles I linked above go into great detail about it, but I assume yo haven’t read them.
The OBR forecast is for a 0.27% hit to growth per year over 15 years mostly due to a loss in comparative advantage
What’s not in the forecast is any benefit from regulating using common law, which is worth at least 0.7% extra growth per year
In 2001, Professor Paul Mahoney demonstrated that countries with legal systems based on the
common law not only have more developed financial markets, but also experienced faster
economic growth in the second half of the 20th century compared to civil law countries.36 Based
on data from 102 countries, the analysis shows that between 1960 and 1992, the real per capita
GDP growth for common law countries grew, on average, 0.71% faster than the civil law
countries.
