担忧

Some of the neuroeconomics topics we are studying at Caltech include: Why people find it difficult to attach dollar prices to goods that are not traded (like environmental harm, health, and safety); whether having too many choices actually makes people less happy with what they own; thinking strategically about what other people will do, when you are trying to outguess them or cooperate with them; how people behave when they fear economic unknowns (like starting small business or investing in countries with unstable political systems); deception in bargaining; the neural foundations of intrinsic motivation for working hard, like intellectual curiosity; and moods and investor sentiment in stock markets.

目前我们在加州理工学院从事神经经济学研究的课题项目包括：为什麽人们认为给不能用以交换的商品(如环境损害、健康、安全)定价格是困难的；面对太多的选择是否使人们竟然对自己拥有的现状感觉不甚愉快；当你试图智算他人或与他人合作时，从策略上考虑他们将做什麽；当人们担忧经济不可预测时（如：开创小企业，或投资于政治体系不稳定的国家），他们将采取什麽样的行为；讨价还价的骗术；努力工作的内在动机的神经基础；心态和投资者对股票市场的情绪，等等。
