Over the past thirty to forty years, globalization has opened many markets around the world to each other. Andrew Charlton has made a career out of studying how different countries trade and work with each other to develop their own economies, and how that has affected the world economy as a whole. Charlton has published many studies, articles, and essays on his research and findings on macroeconomics, specifically on how the Australian economy is affected. Charlton has also written books on how he thinks the world economy could be made fairer and more advantageous to developing economies in Third World countries.
