UK, Mexico, and Canada had also high employment effect of 1.02 million, 783 thousand, and 341 thousand. (2) The total GDP contribution was the highest in the United States with $ 393.8 billion. It reached ￡ 35.9 billion in the UK, CAD$ 27.5 billion in Canada and US$ 25.1 billion in Mexico. (3) UK ranked highest with 3.83 percent of GDP contributions. US, Mexico and Canada also saw 2.4percent, 2.41 percent and 1.51 percent respectively, contributing to the economic contribution of the MICE Industries. It is also necessary for our nation to adopt internationally standardized methodology to analyse the employment effects and economic contribution of the MICE Industries. Also, it would be important to understand the relative position of our industry, comparing the results to other countries.
