I want to know the answer to the following question:
In what year did the UNDP respond to the criticism of its report?
All the background I'm provided with is that "The authors suggest that the United Nations should discontinue the practice of classifying countries into development bins because - they claim - the cut-off values seem arbitrary, can provide incentives for strategic behavior in reporting official statistics, and have the potential to misguide politicians, investors, charity donors and the public who use the HDI at large.[citation needed]". Is that enough to answer the question?
