As an AI language model, I don’t have access to real-time data or the ability to predict events in the future. I can provide information and analysis based on historical data or general trends, but I cannot provide specific details about the top winners and losers in the world economy in 2023. Economic outcomes depend on various factors such as geopolitical events, policy changes, technological advancements, and natural disasters, making it challenging to accurately predict the winners and losers in a specific year. For up-to-date and accurate information about the world economy, it is recommended to refer to reliable sources or consult economic analysts and experts.
