I’m currently developing a theory I’ve named the "Coetzee World Cup Effect", which explores how hosting mega-events like the FIFA World Cup or the Olympics often leads to a temporary spike in GDP, followed by post-event stagnation due to underused infrastructure and unsustainable spending.

I'm still in the process of refining this theory and conducting comparative case studies (e.g., South Africa 2010, Brazil 2014, South Korea/Japan 2002). These cases show a pattern: short-term economic gains (job creation, tourism, FDI), followed by underwhelming long-term benefits.

As part of my research, I’m looking to understand:

• What practical strategies or policies have countries successfully implemented to maintain economic momentum after mega-events?
• Are there case studies of infrastructure being repurposed effectively or integrated into long-term development?
• What role can year-round tourism models, policy incentives, or event diversification play in mitigating post-event GDP decline?

Any insights, models, papers, or recommendations would be extremely helpful as I continue to develop this theory and its applications, particularly for countries like South Africa.
