Although globalization has produced remarkable opportunities and improvements in the lives of people around the world, there are a number of others who have suffered increased insecurity, according to an Indian scholar who, in 1998, became the first Asian economist to win a Nobel Prize.

More efforts should be made to understand the nature and causes of the problem so that remedies can be implemented, Amartya Sen, master of Trinity College at the University of Cambridge in Britain, told a lecture meeting Monday at the Keidanren Kaikan building in Tokyo.

Sen has written many books dealing with economic inequality, poverty and social welfare, and has contributed to the field of welfare economics. He jointly chairs the Commission on Human Security, an independent body established in 2001 to explore ways to reduce human suffering and insecurity, with Sadako Ogata, the former United Nations high commissioner for refugees.
