The poor are often most 1to their effects. Instead of 2responding to crises, aid workers an
2、d policymakers should anticipate and help to guard against such rare and 3disastrous events. After the world suffered major crises in 2008, the concept of risk management has gained 4in international development. The links between risk, livelihoods and poverty are all too clear. Mounting evidence sh
3、ows that 5shocksabove all, health and weather shocks and economic crisesplay a major role in pushing households below the poverty line and keeping them there. But forward-thinking interventions can help 6the costs of future shocks. Bangladesh offers a good example. In 1970, a large typhoon caused 30
4、0,000 deaths in Bangladesh. In 2007, a typhoon of the same 7and strength caused only 4,000 deaths. The reason for the change was that the country had built a number of shelters. It went from having only 12 shelters in 1970 to having 2,500 in 2007. It also had a system of warning the population and a
5、 system of 8these events. But risk management isnt just about lessening the effects of crises; it can also help people get ahead. Farmers in Ghana and India who had access to rainfall insurance were more likely to 9in fertilizer, seeds, and other farming inputs, the report said, instead of sitting o
6、n their money to guard against potential future shocks. Several recent studies have predicted that extreme events will become more common.

8、es. Credit scores, G.P.A.s, SATs, blood pressure and cholesterol(胆固醇)levelsyou name it. So heres a new score to obsess about: the e-score, an online calculation that is assuming an increasingly important, and controversial, role in e-commerce. BThese digital scores, known broadly as consumer valuati
9、on or buying-power scores, measure our potential value as customers. Whats your e-score? Youll probably never know. Thats because they are largely invisible to the public. But they are highly valuable to companies that wantor in some cases, dont wantto have you as their customer. COnline consumer sc
10、ores are calculated by a handful of start-ups, as well as a few financial services, that specialize in the flourishing field of predictive consumer analytics. It is a Google like business, one fueled by almost unimaginable amounts of data and powered by complex computer algorithms(算法). The result is
11、 a private, digital ranking of American society unlike anything that has come before. A company, called eBureau, develops eScoresits name for custom scoring algorithmsto predict whether someone is likely to become a customer. Gordy Meyer, the founder and chief executive, says his system needs less t
12、han a second to size up a consumer and to transmit his or her score to an eBureau client. DIts true that credit scores, based on personal credit reports, have been around for decades. And direct marketing companies have long ranked consumers by their socioeconomic status. But e-scores go further. Th
13、ey can take into account facts like occupation, salary and home value to spending on luxury goods or pet food, and do it all with algorithms that their creators say accurately predict spending. EA growing number of companies, including banks, credit and debit card(借记卡)providers, insurers and online
14、educational institutions are using these scores to choose whom to persuade on the Web. These scores can determine whether someone deserves a super credit card or a plain one, a full-service cable plan or none at all. They can determine whether a customer is routed promptly to an attentive service ag
15、ent or moved to an overflow call center. FFederal regulators and consumer advocates worry that these scores could eventually put some consumers at a disadvantage, particularly those under financial stress. In effect, they say, the scores could create a new subprime class: people who are bypassed by
16、companies online without even knowing it. Financial institutions, in particular, might avoid people with low scores, reducing those peoples access to home loans, credit cards and insurance. G“The scoring is a tool to enable financial institutions to make decisions about financing based on unconventi
17、onal methods,“ says David Vladeck, the director of the bureau of consumer protection at the Federal Trade Commission. “We are troubled by these practices.“ HFederal law governs the use of old-fashioned credit scores. Companies must have a legally permissible purpose before checking consumers credit
18、reports and must alert them if they are denied credit or insurance based on information in those reports. But the law does not extend to the new valuation scores because they are derived from nontraditional data and promoted for marketing. Ed Mierzwinski, consumer program director at the United Stat
19、es Public Interest Research Group in Washington, worries that federal laws havent kept pace with change in the digital age. I“Theres a nontransparent scoring system that collects information about you to generate a score and what your score is results in the offers you get on the Internet,“ he says.
20、 “In most cases, you dont know who is collecting the information, you dont know what predictions they have made about you, or the potential for being denied choice or paying too much.“ JHeres how e-scores work: A client submits a data set containing names of tens of thousands of sales leads(线索)it ha
21、s already bought, along with the names of leads who went on to become customers. EBureau then adds several thousand detailslike age, income, occupation, property value, length of residence and retail historyfrom its databases to each customer profile. From those raw data points, the system calculate
22、s up to 50,000 additional variables per person. Then it searches thoroughly all that data for the rare common factors among the existing customer base. The result scores prospective customers based on their resemblance to previous customers. KE-scores might range from 0 to 99, with 99 indicating a c
23、onsumer who is a likely return on investment and 0 indicating an unprofitable one. But in some industries, “knowing the bottom is more important than knowing the top,“ Mr. Meyer says. In online education, for instance, e-scores help schools distinguish prospective students who are not worth the inve
