Facts about YouTube

From a new and very important paper by Kevin Munger and Joseph Phillips from Penn State: The most extreme branches of the AIN (the Alt-Right and Alt-Lite) have been in decline since mid-2017. However, the Alt-Right’s remaining audience is more engaged than any other audience, in terms of likes and comments per view on their videos. The bulk of the growth in terms of both video production and viewership over the past two years has come from the entry of mainstream conservatives into the...

Who tips on Uber?

Men tip 12 percent more if their driver is a woman, but that’s entirely because they give more money to the youngest female drivers. The premium men pay to women behind the wheel shrinks as the women get older. By the time the drivers are age 65, it has virtually vanished. Women also tip other women more, but they don’t significantly change their tips based on the driver’s age. Tips are highest between 3 a.m. and 5 a.m., and not surprisingly: Tips are highest in small cities and the middle of...

Academic vita fraud?

A recent study of 180 academic curricula vitae found that 56 percent that claimed to have at least one publication contained at least one unverifiable or inaccurate publication, and it suggests that CV falsification could be much more common than scholars committed to professional integrity might hope. The study is small — the 56 percent reflects only 79 CVs, of 141 that claimed to have at least one publication. The researchers behind the study make no presumption as to whether the errors...

Ranking states by their degree of regulation

Now Mercatus has completed an analysis of state-level regulation. State RegData 1.0 analyzes the administrative codes of 46 states plus the District of Columbia, and the results are informative. The average state has 131,000 restrictive terms and about 9 million words in its code, which would require roughly twelve work weeks to read at a normal reading pace. But there is huge variation. The least regulated state is South Dakota, with about 44,000 regulatory restrictions, while the most...

Facebook and privacy

Oops, this blog post isn’t about Facebook at all!  Here goes: Records and interviews show that colleges are building vast repositories of data on prospective students — scanning test scores, Zip codes, high school transcripts, academic interests, Web browsing histories, ethnic backgrounds and household incomes for clues about which students would make the best candidates for admission. At many schools, this data is used to give students a score from 1 to 100, which determines how much...

China estimate of the day

The estimates imply that trade with China increased U.S. consumer surplus by about $400,000 per displaced job, and that product categories catering to low-income consumers experienced larger price declines. That is from a new paper by Xavier Jaravel and Erick Sager. The post China estimate of the day appeared first on Marginal REVOLUTION.

The economic effects of private equity buyouts

We examine thousands of U.S. private equity (PE) buyouts from 1980 to 2013, a period that saw huge swings in credit market tightness and GDP growth. Our results show striking, systematic differences in the real-side effects of PE buyouts, depending on buyout type and external conditions. Employment at target firms shrinks 13% over two years in buyouts of publicly listed firms but expands 13% in buyouts of privately held firms, both relative to contemporaneous outcomes at control firms. Labor...

Education fact of the day

Estimates suggest an average annual consumption value of college as high as $11,600, with considerable heterogeneity across students. Incorporating these benefits raises the average expected return to college by as much as 14%. That is from a new NBER working paper by Yifan Gong, Lance Lochner, Ralph Stinebrickner, and Todd R. Stinebrickner. The post Education fact of the day appeared first on Marginal REVOLUTION.

California state taxes are too high and that is a problem

Among top-bracket California taxpayers, outward migration and behavioral responses by stayers together eroded 45.2% of the windfall tax revenues from the reform. That is from a new NBER working paper by Joshua Rauh and Ryan J. Shyux.  Here is the full abstract: Drawing on the universe of California income tax filings and the variation imposed by a 2012 tax increase of up to 3 percentage points for high-income households, we present new findings about the effects of personal income taxation on...

The real China shock came to Mexico

Mexican manufacturing job loss induced by competition with China increases cocaine trafficking and violence, particularly in municipalities with transnational criminal organizations. When it becomes more lucrative to traffic drugs because changes in local labor markets lower the opportunity cost of criminal employment, criminal organizations plausibly fight to gain control. The evidence supports a Becker-style model in which the elasticity between legitimate and criminal employment is...
