ABOUT RAJ'S WORK
Raj Chetty is an economist whose rigorous theoretical and empirical studies are informing the design of effective government policy.  His initial work focused on resolving inconsistencies in earlier theories of specific questions in public finance, such as how dividend tax cuts affect corporate behavior and how unemployment insurance affects job-seeking behavior. More recently, he and colleagues designed novel empirical tests to gauge the impact of sales taxes on demand. In a study at a large supermarket chain, they demonstrated that, although most customers were well-informed about the retail sales tax rates, consumers purchased less of a product when posted prices indicated the associated sales tax than when the tax was simply added to the product’s base price at checkout. This observation, suggesting that the way in which a tax is perceived can have as much or more impact on consumer decision making as the tax itself, is an important contribution to the emerging field of behavioral public finance. Using large administrative databases drawn from tax and social security records in the United States and Europe, Chetty currently is exploring a range of other questions, such as the effect of tax policy on how much people work, the extent to which tax deductions for retirement savings stimulate individual savings, and key aspects of early childhood education. In a study on teacher quality using these data sets and information gleaned from school district databases, Chetty and colleagues found that, adjusting for other factors, students who by chance were assigned to talented teachers in elementary school had significantly higher incomes as adults and better future life outcomes more generally. By asking simple, penetrating questions and developing rigorous theoretical and empirical tests, Chetty’s timely, often surprising, findings in applied economics are illuminating key policy issues of our time.

BIOGRAPHY
Raj Chetty received a B.A. (2000) and a Ph.D. (2003) from Harvard University. He was a faculty member at the University of California at Berkeley (2003–2009) prior to his appointment at Harvard University, where he is currently a professor in the Department of Economics and director of the Lab for Economic Applications and Policy. His articles have appeared in such publications as the Quarterly Journal of Economics, American Economic Review, Annual Review of Economics, and Econometrica, among others.

关于拉吉的工作
拉吉-切蒂是一位经济学家，他严谨的理论和实证研究为有效的政府政策设计提供了参考。 他最初的工作重点是解决早期公共财政具体问题的理论不一致的问题，如红利税削减如何影响企业行为以及失业保险如何影响求职行为。最近，他和同事们设计了新的实证测试来衡量销售税对需求的影响。在一家大型连锁超市的研究中，他们证明，尽管大多数顾客对零售销售税率很了解，但当公布的价格显示出相关的销售税时，消费者购买的产品比在结账时简单地将税加到产品的基本价格上时要少。这一观察结果表明，对税收的感知方式对消费者决策的影响不亚于税收本身，是对新兴的公共财政行为领域的一个重要贡献。利用从美国和欧洲的税收和社会保障记录中提取的大型行政数据库，切蒂目前正在探索一系列其他问题，如税收政策对人们工作程度的影响，退休储蓄的减税对个人储蓄的刺激程度，以及早期儿童教育的关键方面。在一项关于教师质量的研究中，使用这些数据集和从学区数据库中收集的信息，Chetty及其同事发现，在对其他因素进行调整后，那些在小学时偶然被分配到优秀教师身边的学生，在成年后的收入明显更高，未来的生活结果也更普遍。通过提出简单而有深度的问题，并进行严格的理论和经验检验，Chetty在应用经济学方面的及时发现，往往令人惊讶，阐明了我们时代的关键政策问题。
