My career has been varied. 
In the 1970s, I taught economics at the University of California, Santa Cruz (Kresge College).  Not getting tenure, I taught myself accounting and worked for the next 30 years as a GL accountant and financial analyst 
for a variety of companies in Silicon Valley and Hollister, CA.

During that time, I have greatly developed my writing and business economics analytic skills by writing and posting numerous papers on 2 websites.  This website contains a blend economics, accounting, financial analysis applied to variety of subjects.

My other website
nu-retail.com lists 42 papers  focusing on the economics and business model of pharmacy benefit managers (PBMs)
