From University of Virginia Working Paper:
This paper studies how collecting offender DNA profiles affects offenders’ later recidivism and likelihood of getting caught by exploiting a large expansion of Denmark’s DNA database. We find that DNA profiling increases detection probability and reduces recidivism within the following year by as much as 43%. We estimate the elasticity of criminal behavior with respect to the probability of detection to be -1.7, implying that a 1% higher detection probability reduces crime by almost 2%. We also find that DNA profiling changes non-criminal behavior: profiled offenders are more likely to engage in a stable relationship, and live with their children.

Every book is the wreck of a perfect idea.

From Iris Murdoch:
I think being a woman is like being Irish... Everyone says you're important and nice, but you take second place all the time.

From Iris Murdoch:
Of course reading and thinking are important but, my God, food is important too.

From Policy Studies Journal:
Seeking to test two commonly proposed solutions to gun deaths in the United States, we examine the extent to which (1) tougher gun control laws, (2) greater access to mental health services, and (3) a combination of both approaches affect the rate of gun deaths in American states. We find that tougher gun control laws, as well as a combination of both approaches, are associated with a lower overall rate of gun deaths, and with a lower rate of nonsuicide gun deaths, while only tougher gun control laws are significantly associated with a reduction in the rate of gun-related suicides. Our findings serve as an initial guide to policymakers seeking to reduce the rate of gun deaths in their states.

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...
