You will be given a definition of a task first, then some input of the task.
In this task, you are given a text of many news articles seperated by special token "|||||". Your task is to summarize them.

In tough economic times, parents financially favor daughters over sons, according to researchers at the Carlson School of Management and Rutgers Business School. Their study, forthcoming in the Journal of Consumer Research, found participants preferred to enroll a daughter rather than a son in beneficial programs, preferred to give a U.S. Treasury bond to a daughter rather than a son, and bequeathed a greater share of their assets to female offspring in their will when they perceived economic conditions to be poor. 
  
 "Almost all parents say that they don't favor one of their children over another, but economic recessions subconsciously lead parents to prefer girls over boys," said Rutgers professor of marketing Kristina Durante, lead author of the study. 
  
 In one experiment, 629 participants read a news article that described the economy as either improving, getting worse, or neutral. They then were asked to make a will dividing their assets between an imaginary son and daughter as well as assign one to a beneficial program. Those led to believe tough economic times were ahead, allocated nearly 60 percent of their available resources to the girl compared to a nearly 50/50 split between the two children when economic conditions were viewed as either neutral or prosperous. 
  
 "These findings in humans align well with the behavior of other animals," adds Professor Vladas Griskevicius of the Carlson School. "When resources are scarce parents prefer females because they have a larger reproductive payoff. Almost every female child will produce some offspring, but many male children end up having zero offspring."

 Another experiment in the paper explored the boundaries of age on resources allocation. As expected, the bias toward females was stronger as the children moved closer to reproductive age. 
  
 U.S. Spending Patterns Support Study's Findings 
  
 To bolster the findings in their experiments, the researchers also examined the relationship between U.S. Real GDP and retail spending on apparel for boys and girls between 1984 and 2011. They discovered that when the economy was struggling, the ratio of spending on girls versus boys increased 19.8 percent compared to when the economy was faring well. 
  
 "As the GDP decreased, relative spending on girls versus boys increased," said Associate Professor Joseph Redden of the Carlson School. 
  
 Results Offer Lessons for Parents and Marketers 
  
 "Spending on Daughters Versus Sons in Economic Recessions" has implications for both parents and businesses. By being aware that they can unwittingly bias their spending toward specific children, parents can more carefully track specific spending to maintain equity. 
  
 "When we survey parents, it's very clear they want to treat their children equally," says Redden. "But if they're relying on feelings for how they're allocating resources, it's very likely this bias is seeping in, especially when times are tougher and they don't have money to do everything," added Redden. 
  
 For companies, recognizing the consumer bias towards girls in difficult economic times could allow them to better optimize manufacturing, sales, and marketing efforts.

 Although parents often try not to favor one child, we examine whether specific environmental factors might bias parents to favor children of one sex over the other. This research draws on theory in evolutionary biology suggesting that investment in female versus male offspring depends on resource availability. Applying this to consumers, a series of experiments show that poor economic conditions favor resource allocations to daughters over sons. For example, poor conditions led people to bequeath more assets to girls in their will, and to choose girls to receive a U.S. Treasury bond and a beneficial extracurricular activity. It is proposed that this happens because spending on children represents a reproductive investment, and that boys' and girls' relative reproductive value varies with economic conditions. Supporting this account, perceptions of which child will have more children statistically mediates the effect of economic conditions on preferences for girls. Consequently, the effect is strengthened as a child approaches reproductive age, and is moderated by individual differences (risk aversion and monogamy) directly related to our theoretical model. This research contributes to the consumer behavior literature by revealing how, why, and when environmental factors influence spending on girls versus boys. |||||
Output:
"Almost all parents say that they don't favor one of their children over another," says the lead author of a new study that shows that sentiment flies out the window when times get tough, because "economic recessions subconsciously lead parents to prefer girls over boys." The idea, per the study in the Journal of Consumer Research, is that parents are instinctively inclined to help the survival of their species, and, as another researcher adds, "when resources are scarce, parents prefer females because they have a larger reproductive payoff. Almost every female child will produce some offspring, but many male children end up having zero offspring." To test this bias in humans, researchers enlisted 629 people and showed them a news article that described the economy as neutral, getting better, or getting worse. Asked to divide their assets between an imaginary daughter and son, as well as assign one to a benefits program, the split was 50/50 when times were good or neutral, but 60/40 in favor of daughters when the economic forecast was bleak, reports Phys.org. And as those kids approached reproductive age, the bias sharpened. "It's very clear (parents) want to treat their children equally," says a third researcher. "But if they're relying on feelings for how they're allocating resources, it's very likely this bias is seeping in, especially when ... they don't have money to do everything." (Meanwhile, daughters of working moms make more money.)
