Esther Duflo: Social experiments to fight poverty

poverty

 

Here’s one big question: what has happened to poverty? While optimists talk about flourishing economic growth and proudly declare that this disease will end sooner or later, realists, or the skeptics, point out worsening inequality in nearly all parts of the world as the main consequence of globalization. Despite an ever increasing abundance of various materials amid a burgeoning world population now 7.2 billion strong, 40% among them still earn 2 US$ a day or even less – threshold of what constitutes as ‘economic poverty’ in developing world.

Hundred billions of dollars, the countless of it, have been spent by industrialized countries for decades to help lift these people from the satanic cycle that has plagued them for generations – for little effects. Food production has now enabled surpluses, but people go hungry. Latest marvels in medical technology have shown their potential to heal a great many diseases, but millions of people remain untreated for diseases that are easily recoverable. Children still drop out of school and are entrapped in labor exploitation. What is happening here?

Esther Duflo, a development economist, believes that the root of this problem lies in rampant mismanagement of available resources. The TED talk below offers a detailed explanation, and also solutions as well as examples, on how to handle these mistakes.

 

How to save yourself from ultraviolet: grow beards

Need any beard-implanting services to prevent yourself from skin cancer, I suppose? And somebody please explain what the professors are actually mentioning about regarding the experiment’s background.

Excerpt:

A dosimetric technique has been employed to establish the amount of erythemal ultraviolet radiation (UVR) protection provided by facial hair considering the influence of solar zenith angle (SZA) and beard–moustache length. The facial hair reduced the exposure ratios (ERs) to approximately one-third of those to the sites with no hair. The variation in the ERs over the different sites was reduced compared with the cases with no beard. The ultraviolet protection factor (UPF) provided by the facial hair ranged from 2 to 21. The UPF decreases with increasing SZA. The minimum UPF was in the 53–62° range. The longer hair provides a higher UPF at the smaller SZA, but the difference between the protection provided by the longer hair compared with the shorter hair reduces with increasing SZA. Protection from UVR is provided by the facial hair; however, it is not very high, particularly at the higher SZA.
