"Epidemiology is a difficult topic. I think that if economists are going to contribute anything to the field, it not be by doing studies based on regression methods. If anything, we should contribute skepticism about such methods, based on what we have learned about the biases caused by specification searches, data mining, and the bias toward publishing only 'significant' effects (that bias itself undermines the reported significance). Instead, look for natural experiments, and don't forget to be skeptical of those, too." (01/02/11)
