I guess that might be a question of how "orthodox" you want to be in  
your definition of economics  
  
broadly, Transcendentalism (T) was inspired by certain strands of Indian  
philosophy both directly ... and indirectly (via the Romantic movement  
in the UK and the Continent, for instance)  
  
T contributed to the rise of the "green" movement, which is at least  
partly responsible for current efforts to re-orient economics from the  
purely mathematical to the broadly human, with impacts on related  
fields, e.g., in the move towards "full environmental costs accounting"  
(if I may call it that)   
  
T has contributed also the revival of religion and spirituality in the  
West, and so, e.g., to the thinking behind the book, Jubilee Manifesto  
(edited by Michael Schluter and John Ashcroft) - which has chapters on  
Economics, Finance, Welfare, Nationhood, Government and so on  
  
however, when all that is put together, the influence of T on economics  
(as it stands at present) is at some removes and of only marginal effect  
at present, as far as I can intuit  
  
but i will be pleased to be corrected by those more knowledgeable than  
myself....
