Hi,

My name is Danilo and I am a PhD student in 
economics at University of São Paulo, Brazil.

I am interested in studying the evolution of the 
"natural rate of unemployment" hypothesis, first 
introduced by Phelps and Friedman in the 1960's.

I sense that their original ideas were slightly 
different and produced different developments as 
well. On one hand, the new classicals turned it 
into a radical equilibrium hypothesis through 
walrasian market-clearing microfoundations. On 
the other, the new keynesians turned it into a 
softer hypothesis through the concept of NAIRU.

I would like to ask this list if someone knows of 
any historical account already published about 
the natural rate and its developments. If you 
prefer to respond to me personally instead of to 
the list, my e-mail address is [log in to unmask]

Thank you in advance for your help, best regards,

Danilo Ramalho
