From Journal of Experimental Criminology:
Using National Incidence Based Reporting System data and city-reported data from Chicago, New York, Philadelphia, and Los Angeles, we calculated the difference in assault rates on the Monday immediately following daylight saving time (DST) as compared to the Monday a week later using a Poisson quasi-maximum likelihood estimator model. The same analyses were performed to examine effects of the return to standard time in the fall. We employed several falsification checks.
There were 2.9% fewer (95% CI: –4.2%, −1.6%, p < 0.0001) assaults immediately following DST, when we lose an hour, as compared to a week later. In contrast, there was a 2.8% rise in assaults immediately following the return to standard time, when an hour is gained, as compared to a week later (95% CI: 1.5%, 4.2%, p < 0.0001). Multiple falsification analyses suggest the spring findings to be robust, while the evidence to support the fall findings is weaker.
This study suggests that mild and short-term changes in sleep do significantly affect rates of assault. Specifically, there is support for the theory that mild sleepiness possibly associated with an hour loss of sleep results in reduced assaults. This contradicts the simple inverse relationship currently suggested by most of the correlational literature. This study and the mixed findings presented by experimental studies indicate that measurement variability of both sleep and aggression may result in conflicting findings.

From Economic Journal:
We exploit within-state variation across time in both the existence and length of statutory delays — both explicit wait periods and delays created by licensing requirements — between the purchase and delivery of a firearm to examine the effect of purchase delays on homicides and suicides. We find that the existence of a purchase delay reduces firearm related suicides by between 2 to 5 percent with no statistically significant increase in non-firearm suicides. Purchase delays are not associated with statistically significant changes in homicide rates.

From Intelligence:
Intelligence has been linked with success across a wide array of life domains. To date, however, relatively little research has examined whether intelligence may predict criminal success—that is, engaging in criminal behaviors, but escaping detection and arrest. The current study addresses this gap in the literature by examining the associations among verbal intelligence, criminal involvement, and criminal justice processing (i.e., arrest) using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health). Our findings reveal that verbal intelligence is associated with criminal justice processing, wherein individuals with higher verbal intelligence scores are more likely to avoid arrest for criminal behavior when compared with individuals with comparatively lower verbal intelligence scores. We discuss the implications of these findings for future research.

From The New York Times : We are willing to pay a premium for convenience, of course — more than we often realize we are willing to pay. During the late 1990s, for example, technologies of music distribution like Napster made it possible to get music online at no cost, and lots of people availed themselves of the option. But though it remains easy to get music free, no one really does it anymore. Why? Because the introduction of the iTunes store in 2003 made buying music even more convenient than illegally downloading it. Convenient beat out free. As task after task becomes easier, the growing expectation of convenience exerts a pressure on everything else to be easy or get left behind. We are spoiled by immediacy and become annoyed by tasks that remain at the old level of effort and time. When you can skip the line and buy concert tickets on your phone, waiting in line to vote in an election is irritating. This is especially true for those who have never had to wait in lines (whic...

From The Economist : An equity is a claim on the assets and the profits of a firm; a bond entitles the investor to a series of interest payments and repayment on maturity. Bitcoin brings no cashflows to the owner; the only return will come via a rise in price. When there is no obvious way of valuing an asset, it is hard to say that one target price is less likely than another. Bitcoin could be worth $10 or $100,000. One argument made by bitcoinnoisseurs is that it is a type of “digital gold”. Stores of value are supposed to keep their value; bitcoin, by contrast, is extremely volatile. Its code ensures that no more than 21m coins can ever be created; that sets bitcoin apart from fiat money, which central banks can create at will. Yet being limited in supply is a necessary, but not sufficient, condition for having value; signed photographs of Economist journalists are rare but, sadly, of negligible worth. Nor is supply really limited. Plenty of other cryptocurrencies exist. If the...

From The New York Times : [Steven] Pinker contends that we should not be nostalgic for the economy of the 1950s, when jobs were plentiful and unions strong. A third of American children lived in poverty. Sixty percent of seniors had incomes below $1,000 a year. Only half the population had any savings in the bank at all. Between 1979 and 2014, meanwhile, the percentage of poor Americans dropped to 20 percent from 24 percent. The percentage of lower-middle-class Americans dropped to 17 from 24. The percentage of Americans who were upper middle class (earning $100,000 to $350,000) shot upward to 30 percent from 13 percent. There’s a fair bit of social mobility. Half of all Americans wind up in the top 10 percent of earners at at least one point in their career. One in nine spend some time in the top 1 percent. Poverty has been transformed by falling prices and government support. “When poverty is defined in terms of what people consume rather than what they earn, we find that the...
