Emmanuel Saez (born November 26, 1972) is a French and American economist who is Professor of Economics at the University of California, Berkeley.〔(【引用サイトリンク】title=University of California, Berkeley )〕 His work, done with Thomas Piketty, includes tracking the incomes of the poor, middle class and rich around the world. Their work shows that top earners in the United States have taken an increasingly larger share of overall income over the last three decades, with almost as much inequality as before the Great Depression. He recommends much higher taxes on the rich, up to 70% or 90%.〔(For Two Economists, the Buffett Rule Is Just a Start ) by Annie Lowrey, New York Times, April 16, 2012〕 He received the John Bates Clark Medal in 2009 and was named a MacArthur Fellow in 2010. ==Research== Saez has written extensively on the theory of optimal taxation and transfer, addressing topics such as wealth and income inequality, capital income taxation, and retirement. In addition to his theoretical work, he has authored a number of empirical papers, many of them applying the results from his theoretical work to US household data. His focus on the top 0.1 % of the income and wealth distribution has led to his political theories about the "great compression" and the "great divergence"〔The "Great Divergence" http://img.slate.com/media/3/100914_NoahT_GreatDivergence.pdf〕〔The Evolution of Top Incomes: A Historical and International Perspective http://elsa.berkeley.edu/~saez/piketty-saezAEAPP06.pdf〕 and led to significant research on the consensus about the ideal wealth distribution. Saez's research on wealth and income inequality has largely focused on households at the top of the wealth and income distributions, which make up a significant portion of the US tax base. Conservative critics, such as James Pethokoukis of the American Enterprise Institute, say that Saez and Piketty measure "market income," the total income before tax excluding income from government. Saez describes it as gross income reported on tax returns before any deductions. This excludes unemployment insurance, welfare payments, food stamps, Medicare, Medicaid, Social Security and employer-provided health insurance. Saez says that these are the best data available, as measured consistently since 1913. Critics say that they exaggerate inequality.〔(The Fight Over Inequality ) By THOMAS B. EDSALL, New York Times, April 22, 2012〕 In 2011, Saez and Peter Diamond argued in public media a widely discussed paper〔http://krugman.blogs.nytimes.com/2011/11/22/taxing-job-creators/; http://www.project-syndicate.org/commentary/delong120/English〕 that the proper marginal tax rate for North Atlantic societies and especially the United States to impose is 73% (substantially higher than the current 42.5% top US marginal tax rate). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Emmanuel Saez」の詳細全文を読む スポンサード リンク
