Imagine that you and 99 other people were invited to participate in a bet. All of you have to form a line, provide a one dollar bill on which all of you write your number in the line (from 1 to 100). Host will collect all of your one dollar bills and take them to a room with 100 boxes (each box has its own number (from 1 to 100)). Host will place randomly distribute your bills among the boxes. After he has done this, everyone of you one by one will come into the room and look for your own bill, but you will be able to check only 50 boxes. If every player will find his own bill, then you all will win a game - you will regain your dollar as well as you will additionally get another 100 dollars. But if at least one player makes a mistake, you all will lose. So would you sign up for such bet?

Economic inequality is becoming a forgotten topic, but there are much more to be said about it. In this talk, recorded for ted.com website, Richard Wilkinson provides a lot of examples (based on empirical data), which show how large inequality harms human societies. In order to create a better world for all of us, we should strive for larger economic equality.

In our works we frequently refer to bounded rationality and of human beings. This boundedness causes varying inefficiencies in socio-economic systems. These inefficiencies, or bugs, are not just some strange quirk in the system. These bugs often play major role in forming socio-economic systems as they are observed.

This notion is not new in economics as it has its own branch known as behavioral economics (or behavioral finance). Dan Ariely is one of economists who are interested in human brain bugs on individual and global level. In his talk, recorded for ted.com, he develops one of the aspects behind behavioral economics - human tendency to tell small lies and bypass their own moral code.

In the begging of XXth century economist Harold Hotelling noted that competitors tend to make their products very similar. Currently this observation is known as minimal differentiation principle or Hotelling law. In order to understand what and why is going on, let us imagine one dimensional city.

In this TED talk (recorded for independent TED event) prof. Dirk Helbing talks about the insights, which might be gained from a dialogue between different fields of science (social and physical). This dialogue may event elevate the current civilization to the new level in which we would be able to understand the complexity of our world. This understanding could provide us tools to make optimal, responsible and rational decision making.
