1. Ok, so most people have a vague sense of frustration that the last Dem administration didn't do enough on the economy. But it's still just a vague sense. So my org wrote a report showing in detail, industry sector-by-sector, what policymakers did wrong.

2. We also wrote one pager descriptions of every sector. For instance, in media and telecommunications, there were multiple massive mergers (Comcast-NBC, Disney's roll-up, Charter-Time Warner). https://t.co/es3jzAGVKL
3. Consequences were bad. The median weekly compensation of writer-producers on television and online series declined 23 percent between 2014 and 2016 despite record profits in the industry and peak demand for programming. https://t.co/es3jzAGVKL
4. Health care, consolidation was bad. "From 2010 to 2015, Sanofi, Novo Nordisk, and Eli Lilly raised their insulin prices by 168 percent, 169 percent, and 325 percent, respectively; the three are essentially the only manufacturers of insulin in the U.S."

5. Newspapers, same story. Since 2005, America has lost 2,100 newspapers, one fourth of its total, leaving 1,800 communities without any local news coverage whatsoever. https://t.co/ULmsqCVFRt
6. Defense and aerospace - same story of the ill-effects of consolidation. "From 2008 to 2018, the average cost of a Pentagon weapons system jumped by 13 percent, without accounting for inflation."
https://t.co/tXLRSjGY5M
7. Airlines, same thing. Obama admin fostered three big mergers, United-Continental (2010), Southwest-AirTran (2010), and American-U.S. Airways (2013), and allowed consolidation among online travel agencies. Prices, bag fees, complaints up, wages down.
https://t.co/oAya4BUtSm
8. Agriculture, same thing. Collapse in dairy farming, control of chicken contract growers, massive power of meatpackers, etc. https://t.co/lHVWu02Pgb
9. Big tech, Google and Facebook both grew to utter dominance in online ads, social networking, search, maps, and video from 2009-2017, largely because of the dozens of significant mergers. Obama WH didn't block a single merger. https://t.co/F9lFaaToaQ
10. Same thing for Amazon. Using predatory tactics, it grew from a retailer to a core infrastructure provider across multiple markets, including e-commerce, retailing, logistics, cloud computing, voice assistants, security, and government contracting. https://t.co/PcW84Zydql
11. Finally there's labor and monopoly. Just a disaster. The Justice Department and Federal Trade Commission challenged zero mergers or acquisitions based solely on the mergers’ effects on workers. https://t.co/dQrCe8MkYB
12. In 2016, a bipartisan FTC unanimously opposed the city of Seattle’s attempt to allow Uber and Lyft drivers to bargain collectively.
https://t.co/dQrCe8MkYB
13. After DOJ settled charges against Silicon Valley companies for colluding not to recruit each other’s workers, a class action lawsuit won $415 million for the workers, though the suit estimated the damages at $3 billion. https://t.co/dQrCe8uJA1
14. People have a vague sense things got worse because they *did* get worse. Wages down, prices up, quality down. These changes just happen by themselves. Each happened because of a discrete *choice* by a policymaker. https://t.co/I1fUawW87f
15. People distrust the government because our policymakers showed themselves worthy of distrusting. Joe Biden can win this trust back. And he is running a very different administration than either Obama or Trump did. And we are all learning.
https://t.co/I1fUawW87f
16. @noamscheiber has an important piece on how Joe Biden thinks about the world. Biden wants an 'industrial policy' to finance the growth of domestic production. That's excellent, but he has to recognize the problem of corporate power as a complement. https://t.co/aWmjAImjbU

1/ Trend Factor: Any Economic Gains from Using Information over Investment Horizons? (Han, Zhou, Zhu)

"A trend factor using multiple time lengths outperforms ST reversal, momentum, and LT reversal, which are based on the three price trends separately."

https://t.co/udkvsdw2Lz


2/ This resembles combining multiple measures of ST reversal, momentum, and LT reversal (forecasts determined by walking forward rather than using signs from the full sample).

Unlike normal moving average signals, these are *cross-sectional.* More below:
https://t.co/wkIFLg9jtK


3/ Unsurprisingly, the Trend factor formed by this approach outperforms benchmarks in terms of both Sharpe ratio and tail metrics. It's combining momentum with two factors that are negatively correlated to it AND using multiple specifications.

More here:
https://t.co/x8Tloz3iyL


4/ "Average return and volatility of the trend factor are both higher in recession periods. However, the Sharpe ratio is virtually the same.

"Interestingly, all of the factors still have positive average returns.

"Momentum experiences the greatest increase in volatility."


5/ "In terms of maximum drawdown and the Calmar ratio, the trend factor performs the best.

"The trend factor is correlated with the short-term reversal factor (35%), long-term reversal factor (14%), and the market (20%) but is virtually uncorrelated with the momentum factor."
The argument for deficits & debt raising interest rates in the US is not increased credit risk, it is that interest rates are a function of economic fundamentals, flows & policy. Deficits/debt change those.

I can't tell if I'm agreeing or disagreeing with @jc_econ.


Increasing government spending or reducing taxes increases demand (or reduces saving). This raises the price of loanable funds or the interest rate.

In a dynamic context, more demand means a stronger economy, the central bank raises interest rates sooner, and long rates rise.

(As an aside, we are not close to the United States needing to worry about credit risk and the risks are more overstated than understated in most other advanced economies too. But credit risk is not always & everywhere irrelevant, just look at the UK in 1976 or Canada in 1994.)

Interest rates have fallen over the last 20 yrs while debt has risen. This does not necessarily mean that debt rising causes interest rates to fall. It could also mean that other things have happened at he same time that pushed down interest rates more than debt pushed them up.

The suspects for these "other things" include slower productivity growth, slower popln growth, higher inequality, less investment, etc. All of which either increase the supply of saving or reduce the demand for investment, reducing the equilibrium interest rate.
