The field of public finance is constantly developing. Newapplications of experimental and quasi-experimental techniques measure the impact of public policies, and new insights provided by economic theory into the roles of government spending and taxation.

This book incorporates recent developments and along the way takes its readers to the frontiers of current research and policy. While the information presented is cutting edge and reflects the work of economists currently active in the field, our approach makes it accessible to undergraduates whose only prior exposure to economics is at the introductory level.

公共财政领域不断发展。实验和准实验技术的新应用衡量公共政策的影响，以及经济理论对政府支出和税收作用的新见解。

这本书结合了最近的发展，并一路带读者到当前研究和政策的前沿。虽然所提供的信息是最前沿的，反映了当前活跃在该领域的经济学家的工作，但我们的方法使那些之前只接触经济学入门级的本科生能够获得这些信息
