Input: Consider Input: Article: If you give something to someone for free, will that person value it and use it? Development experts have debated this question for decades. Some think the act of paying causes people to value something and use it more. Selling necessary health treatments, others argue, may deny them to the people who need them the most. Consider, for example, chemically treated bed nets, which kill mosquitoes anti protect people against malaria while they are sleeping. William Easterly, an economist at New York University, believes this is one example of development having gone wrong. In a recent book, Professor Easterly suggests bed nets given free in Africa are often used for the wrong purpose. Yet, the World Health Organization (WHO) recommends bed nets be given out free and used by whole communities. The success of a large free bed net campaign in Kenya led the WHO to announce this recommendation This debate will likely influence social programs in the developing world. Many non-governmental organizations support the creation of self-supporting programs in poor countries. Goods and services are sold for a price to help these programs survive. According to Rachel Glenerster, who runs a research lab doing development and poverty studies at the Massachusetts Institute of Technology, her several studies have proven that small price changes have a big influence on the number of people who use a product. A price change will reduce the total amount of use of the product as well, she says. She has also found no evidence that the very act of paying for something changes how people use it. As for a particular product among special populations, some development experts argue that pricing is useful. When it comes to bed nets, Miss Glenerster says research shows no evidence of this. People are just as likely to use a bed net whether they paid for it or not.

Input: Consider Input: Article: Millions of American kids come home to or leave an empty house every day. However, parents are increasingly using an existing technology -- home security systems -- to keep an eye on their "home-alone" children. In the early days of home security, the systems were basically designed just to keep the bad guys out. Now, many parents are also using them to make their children safe when they are at home alone. Below are some simple rules for adults to teach their children: Every child should memorize his or her own full name and address, and home, work and cellphone numbers of each parent. Also keep this information posted next to the phone at home. If your child is too young to memorize the information, he or she may be too young to be home alone -- for any time. Teach your child to observe things around him or her when he or she returns to the house. If a door or window is slightly open, the child has any reason to suspect someone has been in the house that shouldn't be, have him or her call you, then wait at a safe house a neighbor offers. Warn your child never to answer the doorbell or telephone when they are home alone. Besides, set a rule that he or she must never play outside the house when no one else is at home. Be sure he or she knows how to disarm and arm your home security system. Program your control panel to give you a message when your child enters or leaves the house, and arms or disarms the system. If your child forgets to rearm the system, you can call him or her with a personal reminder.
