And economists argue that this stops social mobility between generations. While for men, the costs are lower.". "We know that across a whole range of behaviours women tend to take fewer risks. But for every offer a man makes, he only has a one in five chance that the desire to meet again is reciprocated. One possible theory is that the person who moves has more confidence. For instance, people from rich privileged backgrounds marry each other, while people from more disadvantaged backgrounds marry each other. That means that for every offer a woman makes, she has roughly a 50-50 chance that the man will want to see her again too. This controlled environment is something that excites some economists as they are perfect for observing market forces at work- in this case the dating market. The men move from table to table for a fleeting date with each woman, lasting typically between three to four minutes. But speed dating shows that people are not too fixed in their views of who they should date, says Belot, if they are given the opportunity. The researchers found that when the roles were reversed at speed dating events, and women moved round to approach the men, they found that women made more offers than they did at events when they sat still.
