Dear all,  
  
In the short run it is not always advisable to visit HET courses   
when the student is going to write a dissertation on economic theory or  
on econometric themes under limited time. It is indeed a hard task to  
persuade our friends of the necessity of HET courses at the graduate  
level. Yet, it does NOT deny the importance of HET for a longer run.  
Having conversations with A. Smith, K. Marx and J. M. Keynes, it enables  
a scholar to look at economic problems from a wider perspective.  
Although you have other means to have good visions, HET certainly is a  
candidate. Of course, it is still arguable whether it gives a higher  
yield compared with other activities in his or her life cycle.
