In a series of blog posts, John Cochrane criticizes the Saez-Zucman proposal for higher wealth taxes. In posts #1 to #4 he argues that economic arguments for wealth taxes are inconsistent or not convincing. In post #5 he concludes that Saez-Zucman truly are motivated by political objectives which are grounded in the view that wealth of the rich is ill-gotten or that the rich have a disproportionate, negative influence on politics. Saez and Zucman want to confiscate billionaires’ wealth,...

Finanz und Wirtschaft, January 4, 2020. PDF. Finance has been digital for decades. And both technology and preferences are only changing gradually. So, what triggers the abrupt changes in business models that we currently observe? The interaction between industry on the one hand and legislators and regulators on the other has changed. New entrants exploit synergies across areas that have so far been regulated by independent authorities, or not at all. While entrants think and act outside...

One of the American Economic Association sessions in this year’s ASSA Meetings focused on “Modern Monetary Theory” (MMT) and (maybe somewhat unfairly in the same session) on last year’s presidential address by Olivier Blanchard, which suggested that persistently low interest rates on public debt render government budget constraints non-binding. Greg Mankiw concluded in his paper that “MMT contains some kernels of truth, but its most novel policy prescriptions do not follow cogently from...

Redrawing the Map of Global Capital Flows: The Role of Cross-Border Financing and Tax Havens, by Antonio Coppola, Matteo Maggiori, Jesse Schreger, and Brent Neiman: We start with the dataset of global mutual fund and exchange traded fund (ETF) holdings provided by Morningstar and assembled in Matteo Maggiori, Brent Neiman and Jesse Schreger (2019a, henceforth MNS). For each position in the data, we link the security’s immediate issuer to its ultimate parent. The resulting data can then be...

The Central Bank of the Bahamas introduces CBDC, according to a press release (December 2019). The intended outcome of Project Sand Dollar is that all residents in The Bahamas would have use of a central bank digital currency, on a modernized technology platform, with an experience and convenience—legally and otherwise—that resembles cash. It is expected that this will allow for reduced service delivery costs, increased transactional efficiency, and an improved overall level of...

On Marginal Revolution, Alex Tabarrok reported (in December 2019) that [m]en and women are different. A seemingly obvious fact to most of humanity but a long-time subject of controversy within psychology. New large-scale results using better empirical methods are resolving the debate, however, in favor of the person in the street. The basic story is that at the broadest level (OCEAN) differences are relatively small but that is because there are large offsetting differences between men...

In an NBER working paper, Gino Gancia, Giacomo Ponzetto, and Jaume Ventura propose a theory of declining public support for economic unions: Broad gains from trade in differentiated goods make way for distributive conflict due to specific factors: … this is partly due to the growth of trade between countries that are increasingly dissimilar. … political support for international unions can grow with their breadth and depth as long as member countries are sufficiently similar....
