Explanation: The dilemma of measuring the developmental level of economies was solved once the United Nations Development Programme (UNDP) published its first Human Development Report (HDR) in 1990.

• The report had a human development index (HDI) which was the first attempt to define and measure the level of development of economies.
• The ‘index’ was a product of select team of leading scholars, development practitoners and members of the Human Development Report office of the UNDP.
• The first such team which developed the HDI was led by Mahbub ul Haq and Inge Kaul. The term ‘human development’ is a corollary of ‘development’ in the index.
