Gender Differences in Risk-Taking: Evidence from Professional Basketball


That is a new paper by René Böheim Christoph Freudenthaler, and Mario Lackner, the abstract is to the point:
We analyze gender differences in risk-taking in high-pressure situations. Using novel data from professional athletes (NBA and WNBA), we find That male teams Increase Their risk-taking Reviews towards the end of matches When a successful strategy risky secure Could winning the match. Female teams, in contrast, reduce Their risk-taking in contention situations. The less time left in a game, the larger is the gap. When the costs of an unsuccessful risky strategy are very broad (losing the tournament), we find no Increase in risk-taking for male teams.
Do you think we this is generalizable across sports?  

Book Review: Freakonomics

Freakonomics by Stephen J. Dubner , Steven D. Levitt 

Original title: Freakonomics: a rogue economist explored the hidden side of everything 

Category:  Economy, politics, sociology and news


If statistics do not exist ... this book would not exist either 


Obviously, therefore, the "ease" of reading will serve as enthusiastic about the skeptics.
A collaboration between a young atypical economist and a journalist from the New York Times, this book is regularly praised in the press for the original approach to certain issues that everyone does not fail to arise one day. Indeed some issues raised by the book are among the questions that could one day touch the mind of the average reader (what are the factors that led to the drop in crime in the 90s, how can earn a drug dealer) others, such as whether sumo fights are rigged, of interest that jumps least in the eyes ... 
This is my first reserve. 
My second reservation concerns the almost systematic use of statistical data. These tend to be used as supreme demonstration tool, although the authors provide warnings of use (beware of hasty conclusions) and strive to respect the distinction between the concept of correlation and the event. 
Another key subject to comparisons and conclusions which the authors engage willingly. Some very crude, are deliberately provocative to trigger these polemics worth all advertising campaigns (after all Levitt is not it a brilliant economist recognized by his peers?). So compare the risk to a crack dealer to be killed in a year (7%) and the risk to a death row inmate to be executed in the same time frame (2%) to conclude that the fate of the former is less desirable than the second seems at least curious. It's cheap to psychological torture that represent years to languish at the bottom of a cell awaiting certain death. As for reconciliation between the legalization of abortion and lower crime fifteen years later, each judge based on his convictions ... 
Finally, last reservation I promise, I think that certain conclusions are perfect clichés circulating for decades in all facs and other conferences devoted to gender issues. Say for example that information, according to which the holding can be a beacon, a stick, an olive branch, a deterrent, seems to me to be obvious. Similarly, we suspected that the organization of crack trafficking, at some level, like that of an ordinary capitalist enterprise. 
I will end on a positive note, because this book is not as flaws, noting that some items are subject to a most unexpected analysis (collective fears and their use, the security policies of major cities ...) even it is rather to sociology.

On the failed coup to oust Turkey's Erdogan

An article in the Saker 
The pro-NATO Military Coup failed after a few hours. The rebels immediately closed the Straits of Dardanelles to all ships to stop Russian ships sailing to and from Syria. The organizers of the coup wanted closer relations with NATO and Washington. The Turks want closer relations with Russia, not with Washington.
The Turks want to survive, eat and stay warm against the coming winter. They need a market with Russia and Russian gas for it. Everyone now knows that any coup pro-Washington means war, foreign occupation, the collapse of the economy, poverty and the death of civilians. Everyone talks of Ukraine as an example [not to follow, OD].

1. The Prime Minister of Turkey said that the country pr
otecting the opposition leader Gulen - who is believed to be an organizer of the military coup - can not be a friend of Turkey. Needless to say he thinks the United States. This is a big step for Turkey to Russia and Eurasia from the west. It seems that Turkey has decided that the non-Western part is winning in the standoff with the West, and they [the Turks] are not really Europeans after all.
2. The mayor of Ankara: " The Russian jet was shot down by people loyal to the shadow government and a radical religious disciple of Gulen to destroy Turkey's relations with Russia."
3. Erdogan demonstrates a political miracle endurance. This is not the case of the Ukrainian Yanukovych, who is hiding in Rostov. For those who say that the militarywanted to give more freedom to the people politically and solve the problem of the Kurds, the military coup was pro-Washington and pro-NATO against Russia, and that is all we need know. I do not support the policy of Erdogan that puts and keeps many people in prisons, including military officers and journalists, but they are good for Russia. A Maidan in Turkey and the Washington Act Turkey would really be devastating.
4. At the beginning of the coup, the Western media, all experts and military analysts were in favor of the coup. The White House was silent. The White House expressed support for the Erdogan government via its tweeter only after it became clear that the coup had failed.Washington is a friend when all is well.
5. After the coup failed, Donald Tusk [President of the EU Council, NdT] is out angry and said that now the EU would change its relations with Turkey. Oh the irony! I can not even comment on it here, it's so deeply profound.
Now on the EU website, he expressed support for the democratically elected Erdogan, hehehe ...
The entire EU government in Mongolia is now trying to persuade the Mongols that they really are a European nation and should stand against undemocratic regimes in Russia and China. The Mongols listen and nod politely, thinking: "These pale devils are really good for nothing."
6. For future reference, the Russian internet is a home for discussions of how they should act if there was a coup against Putin: people everywhere would come out to the streets to support the President, demanding actions FSB.
7. Erdogan said that Turkey could not be managed from Pennsylvania .
8. Good relations with Russia, it is most important to Turkey now.
9. The Prime Minister of Turkey has said that the Turkish Stream Russia is very important for Turkey.
10. Internet is full of pictures of Erdogan receiving an Oscar for his brilliant performance.
11. The Ukrainian media shout everywhere that Turkey is not a democracy and that Erdogan has to go [meaning, following their coup US-EU-Nazis, NdT ].
12. The Turkish soldiers arrested for once, say they were told that it was an exercise; they knew nothing about a coup and did not want to join.
13. Consulate of the United States in Adana in Turkey urgent message to US citizens 16 July: Military base of Incirlik and Adana Airport ...

14. Ria Novosti , and RT TASS reported that members of the coup took control of the frigate Yavuz and removed the commander of the Turkish Navy, according to Reuters referring to a Greek military source.
15. Eight members of the coup landed in Greece in a Turkish military helicopter and requested political asylum. Greece is for the return of the helicopter with the fugitives suddenly Turkish military coup in Ankara.
16. Russia and Turkey have now confirmed their agreement to organize a bilateral meeting between leaders of the two countries.
