Online shoppers would rather receive an offer for a product or service than make their own offer 3 according to a study led by a Michigan State University scholar that has implications for the fast-growing e-commerce industry. The findings may come as a surprise given that shopping online is an anonymous(匿名的）process that seemingly can give consumers more confidence to drive a hard bargain,said Don Conlon ，Professor of Management in MSU’s Broad College of Business.
But the study found that participants who made their own offers were less successful in sealing the deal and ，when they were successful? worried they overpaid Many shoppers found the process of researching an offer to be a hassle. “ Americans are very busy，and it’s less time-consuming to be the one receiving the offer rather than the one proposing the offer ” Conlon said. u People tend to be happier when they’re in the receiver role. ”
Online spending in the United States is expected to jump 45 percent in the next four years， from $ 226 billion this year to $ 327 billion in 2017，according to Forrester Research Inc. Nevertheless, researches into this prosperous market remain largely focused on the strategies of companies, rather than those o£ shoppers. Conlon’s study is ，obviously, a rare exception.
Conlon got the idea for the study after considering the difference between two popular sites for hotels and airline flights, priceline.com, which takes bids, and hotwire.com ，which provides offers. Using these two models ，Conlon and his fellow researchers conducted a series of experiments with more than 850 people who were charged with booking a fictional hotel room and acquiring a fictional antique car. Not only did participants prefer to receive bids, Conlon said ，but they also secured more deals in that receiver role. Further ，when they had to make the bids ，they were left more mentally taxed and regretful.
From an industry perspective，putting customers in the receiver role may help fill more hotel rooms and airplane seats. “If you’re a business with a lot of products3 ” Conlon said，“you may want to be the one making the offers. ” However, when selling single items, such as an antique car， accepting bids may be a better option since that typically drives up the price, he said.

C．Online shoppers don’t bargain as much as expected.

Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.
In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity (长寿). While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.
These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.
