On The Upshot I have a new piece, co-authored with Veronique de Rugy, here is an excerpt:
…the book’s timing may be behind the state of French debate. Had it been released in the halcyon days of Mr. Hollande’s 2011 presidential campaign, when many French considered soak-the-rich talk and 75 percent marginal tax rates to be practical fiscal strategies, Mr. Piketty’s book might have made a bigger splash in France. Today, with the economy still struggling, Mr. Hollande is talking about tax cuts rather tax increases. The 75 percent rate has suffered constitutional challenges, and even celebrity backlashes, such as when Gérard Depardieu pursued and received Russian citizenship to lower his tax rate. Mr. Hollande seems to be steering France away from its traditional role as a defender of high taxes and toward some structural reforms, albeit at a slow pace. During his New Year address, Hollande even turned into a rhetorical supply-sider, making the case for cutting taxes and public spending, improving competitiveness, and creating a more investor-friendly climate. In any case, the French appetite for stiff tax increases has diminished.
…Finally, some other French economists have taken the lead in challenging Mr. Piketty’s empirical claims. One recent paper by four economists at l’Institut d’Etudes Politiques de Paris challenges Mr. Piketty’s view that inequality has increased because the return to capital has been greater than general growth in the economy. The current shorthand is “r > g.”
The paper argues that the higher growth of capital rests entirely on returns to housing, and takes technical issues with the book’s treatment of housing, too. If Mr. Piketty’s argument depends on housing, it hardly seems to match his basic story about the ongoing ascendancy of capitalists.
