I am very interested in accounting and economics issues, especially if  
related to the notion of equilibrium.  
  
As deepened in my work on the foundation of the italian accounting and  
business economics tradition (Economia aziendale) by Gino Zappa (1879-1960),  
"Gino Zappa e la rivoluzione del reddito" CEDAM 2002, this scholar develops  
a very special position : accounting system, no more based on book-keeping  
alone, may be taken  as counter-point agaist the marginal cost pricing  
approach based on equilibrium.  
  
Zappa grounds his theoretical development on the history of accounting and  
economics, with special attention to monetary and measurement problems.  
Thus, further references on equilibrium may be discovered in his work,
