A new theory of monopsony, or how to bargain with trapped miners

In an effort to dominate the miners, the team of psychologists led by Mr Iturra has instituted a series of prizes and punishments. When the miners behave well, they are given TV and mood music. Other treats – like images of the outside world are being held in reserve, as either a carrot or a stick should the miners become unduly feisty.

In a show of strength, the miners have at times refused to listen to the psychologists, insisting that they are well. ''When that happens, we have to say, 'OK, you don't want to speak with psychologists? Perfect. That day you get no TV, there is no music – because we administer these things,''' said Dr Diaz. ''And if they want magazines? Well, then they have to speak to us. This is a daily arm wrestle.''

Here is more.  Here is one upshot:

''NASA told us we have to receive the arrows, so that they don't start shooting the arrows at each other,'' said Dr Diaz.

''So we are putting our chests forward – now they can target the doctors and psychologists.''

In other words, don't be too nice to the miners.  For the pointer I thank The Browser.
