No evidence that ‘yes’ vote good for economy

No global commentator, such as the IMF, World Bank or European Commission, has ever claimed a correlation between the lawfulness of same-sex marriage and economic performance.
It is noteworthy that Germany, Ireland’s most important source of foreign direct investment on the continent, recognises civil partnerships but not same-sex marriage; while Spain, where same-sex marriage is lawful, is coping with an unemployment rate of 23%.
