QUOTE OF THE DAY

“Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage — to move in the opposite direction.”


RETIREMENT FINANCE AND PLANNING

these inconsistencies at the extremes are important to acknowledge. As with any model, understanding it’s sensitivities and limitations is essential so that we don’t use it to answer a question it isn’t fit to reliably answer. 

43 percent of retirees underestimate by at least five years, the life expectancy for someone of their age and gender, the Society of Actuaries reports. Planning for longevity might include working longer, adjusting investment strategies, and planning for incapacitating health problems.  

Future retirees will face a much different retirement landscape and will need to adopt new sets of skills—behavioral and financial—that will help them systematically tap into retirement savings to support future spending…. research conducted by the BlackRock Retirement Institute (BRI) in conjunction with the Employee Benefit Research Institute (EBRI) found that on average across all wealth levels, most current retirees still have 80% of their pre-retirement savings after almost two decades in retirement…These findings begin to challenge industry norms and academic theories about lifecycle consumption especially during the retirement phase… Across all wealth levels measured, more than one third of current retirees grew their assets—leaving considerable potential consumption on the table… Late in life out-of-pocket medical expenses—a major reason to retain assets—do not appear to be warranted except for a very small portion of the population… The financial landscape for future retirees will most likely be more challenging, requiring different savings and spending behaviors.  

In this paper, we demonstrate that contrary to this common belief, institutions that use generational tables (namely, tables including future mortality evolution) will most likely need to make more important adjustments (positive or negative) to their liabilities than will institutions using periodic (static) tables whenever a new table is released. By using three very different models to project mortality, we demonstrate that our findings are inherent in the required long horizons of the forecasts needed in the generational approach, with the uncertainty surrounding the forecast values increasing with the horizon. Therefore, generational tables may introduce more instability in a pension institution’s accounts than periodic tables. [keep an eye on one's counter-parties I say…]



MARKETS AND INVESTING

No predictive power, Star Capital
The data shows no significant statistical relationship between forecasted and realized performance. A naive forecast, assuming a constant annual performance of 9% led to the same forecasting error of 18%. This result holds true for any chosen annual performance forecast between 6% and 21% ...  

The dopamine rush of obtaining something important that you knew would eventually come but didn’t know when is what keeps you hunting for more… [Variable interval] is at the heart of all gambling devices. It has the same effect. A pigeon can become a pathological gambler just as a person can.” Variable interval rewards are why we compulsively check email. Some messages are really important, but you don’t know when the important ones will come, so you keep checking and checking. Same with checking Twitter and Facebook. Or watching cable news. Or waiting for a boring meeting to end. Find something that captures people’s attention and turns them into crazed animals and you will likely find a variable interval reward. Now let’s talk about investing. 



ALTERNATIVE RISK

Cheese, sunflower seeds and rough rice sounds like an unappetizing mix -- unless you happen to be a hedge-fund manager. A handful of computer-driven funds had a bumper 2017 by betting on the future price of such “exotic” assets. The success of this type of managed futures strategy, the industry’s term for trend-following, is now drawing new entrants despite the risks created by the low levels of liquidity. 

Timing the Market: Momentum and Beyond, Pedro Barroso @ CFA Institute.
the Sharpe ratio of investing in momentum is highly predictable. After safe months in the strategy, the Sharpe ratio is about 1.7, while it is only 0.28 after risky months. A naive modified momentum strategy using this predictability has almost double the Sharpe ratio of standard momentum with much less crash risk. This is a much deeper puzzle than original momentum…One interesting result is that the “betting-against-beta” (BAB) strategy has risk management benefits like those of momentum.  

All but one of the index’s 19 components posted gains in 2017.  The top earners were natural resources-metals and mining, which surged 37.1%, emerging markets equity (up 36.8%), emerging markets equity-China (up 31.8%), natural resources-timber (up 29.8%), international real estate (up 26.5%), and equity-international developed (up 26.4%). Managed futures posted the only decline among index constituents, sliding 3.2% during the course of the year. 

Tail Protection for Long Investors: Trend Convexity at Work; Dao, Nguyen, Dreemble, Lemperierier, Bouchaud, Potters. 
The performance of trend following strategies can be ascribed to the difference between long-term and short-term realized variance. We revisit this general result and show that it holds for various definitions of trend strategies. This explains the positive convexity of the aggregate performance of Commodity Trading Advisors (CTAs) which -- when adequately measured -- turns out to be much stronger than anticipated. We also highlight interesting connections with so-called Risk Parity portfolios. Finally, we propose a new portfolio of strangle options that provides a pure exposure to the long-term variance of the underlying, offering yet another viewpoint on the link between trend and volatility. 


SOCIETY AND CAPITAL

…relatively more Norwegian-born persons in Minnesota suffered from mental illness, especially schizophrenia,in the 1920s than did members of Norway’s population [hmmm.  Being from Minnesota and all…] 

Complexity bias is our tendency to look at something that is easy to understand, or look at it when we are in a state of confusion, and view it as having many parts that are difficult to understand. We often find it easier to face a complex problem than a simple one. “Most geniuses—especially those who lead others—prosper not by deconstructing intricate complexities but by exploiting unrecognized simplicities.”… The world around us is a chaotic, entropic place. But it is rare for us to see it that way.

Given robust job growth and the prosperity generated by several industries, it’s worth asking why California has fallen behind, especially when the state’s per-capita GDP increased approximately twice as much as the U.S. average over the five years ending in 2016 (12.5%, compared with 6.27%). It’s not as though California policymakers have neglected to wage war on poverty. 

On November 2, 1983, President Ronald Reagan signed a law establishing a federal holiday for the birthday of Martin Luther King Jr., to be celebrated each year on the third Monday in January. As the legislation that passed Congress said: "such holiday should serve as a time for Americans to reflect on the principles of racial equality and nonviolent social change espoused by Martin Luther King, Jr.." Of course, the case for racial equality stands fundamentally upon principles of justice, not economics. But here are a few economics-related thoughts for the day from the archives:  

Excerpts from the "World Inequality Report 2018, written and coordinated by Facundo Alvaredo, Lucas Chancel, Thomas Piketty, Emmanuel Saez, Gabriel Zucman."
Underlying these overall patterns are some shifts in regional economic patterns that are fairly well-known, but remain striking. For example, this figure looks at average incomes in Africa and across Asia, and  how they compare to the average world income. In 1950, Africa was well ahead of Asia relative to average world income, but that pattern has dramatically reversed.  

"The rate of return on everything" shows that "r" is greater than "g"  by a fair margin, but there are extended periods of negative returns and the return on wealth is highly variable. If you want to join the wealthy class, you have to save to have money to invest. As important, you have to control your wealth return to ensure you don't lose your wealth. Inequality is a problem but wealth-holders take on risk and the certainty of gains are not guaranteed.

English Abstract: …It was found that the correlation of the KOSPI-DJIM portfolio has a stronger linkage than that of the KOSPI-SHX portfolio. From the portfolio perspective, the S&P 500 Sharia stock index(SHX) acts as a better hedge asset than the DJIM against the risk of stock market fluctuations. Lastly, the hedge ratio between the two Islamic stock market and Korean stock market pairs is generally low, indicating that the Korean stock risk can be effectively hedged by taking a short position in the Islamic stock markets. In the comparison with these two pairs, the pair of KOSPI-SHX shows a lower hedging cost than that of the KOSP-DJIM pair. This evidence indicates that the S&P 500 Sharia index plays amore effective hedging role against the risk of Korean stock market fluctuations. 

Despite the conventional wisdom to the contrary, the $15 billion mattress industry has seen the entrance of several ambitious startup companies, and they are starting to put a dent in market share. Today’s infographic from Online Mattress Review tells the story of how disruption is occurring in this unlikely space – and it all starts with big changes to the business model to make online mattress sales more palatable for both the company and the consumers. 

A Short Introduction to the World of Crypto currencies by Aleksander Berentsen and Fabian Schar - St Louis Fed
we give a short introduction to cryptocurrencies and blockchain technology. The focus of the introduction is on Bitcoin, but many elements are shared by other blockchain implementations and alternative cryptoassets. The article covers the original idea and motivation, the mode of operation and possible applications of cryptocurrencies, and blockchain technology. We conclude that Bitcoin has a wide range of interesting applications and that cryptoassets are well suited to become an important asset class. 

"Robot Apocalypse" is a modern expression that refers to a fear of technological advance, but the anxiety goes back centuries.1 In 1589, Queen Elizabeth refused to grant the inventor of a mechanical knitting machine a patent for fear of putting manual knitters out of work. 

To help the least advantaged, is it enough to vote against public policies that seem unjust, or should individuals also give from their own pockets to charities even if they can only help a few people at a time? Brian Berkey, Wharton professor of legal studies and business ethics, believes giving from one’s funds to help others is a moral obligation — and folks should channel their money toward the most effective charities.  Berkey says critics of this approach would rather attack an unjust institution or system to fix the root cause of the social malaise. But he says they are misguided, in part because it is difficult for their efforts to succeed. Shouldn’t a doctor still treat a wounded soldier on a battlefield instead of just protesting against the war? Berkey spoke to Knowledge@Wharton to discuss his reasoning in the paper, “The Institutional Critique of Effective Altruism.” 

We measure the externalities of prostitution by quantifying the discount that households require to live next to a brothel. In our tests, we exploit a unique feature of Amsterdam's Red Light District (RLD), area inside a perimeter naturally delimited by canals where private homes are located next to prostitution windows. Using a novel two-dimensional difference-in-discontinuity (DiD) estimator, we find that households require a discount as high as 24% on homes inside the RLD. We also find that this discount disappears when prostitution windows are forcibly closed by local authorities. By incorporating the exact coordinates of brothel closings, our empirical design allows us to establish a direct link between these closings and changes in price discontinuities. To estimate the economic impact on households outside the RLD, we look at the closings of all brothels in Utrecht (the fourth largest city in the Netherlands) in 2013. Households are found to have paid up to 12% of the value of their home to be some distance from prostitution. In both cities, the contraction of the paid-sex industry is also associated with a drastic reduction in crime rates. Overall, our findings suggest that the nuisances prostitution creates do more harm than good to residents.
