Robert Higgs is Senior Fellow in Political Economy for The Independent Institute (which took over the rump of the Cash for Comments Economists Network, and also the Editor of the Institute’s quarterly journal The Independent Review. The Independent Institute took over fronting the Cash for Comments Economists Network when its leader, Robert D Tollison was exposed as a tobacco shill, and its organiser, James M Savarese was transferred over to work on union bribery though the tobacco industry's Labor Management Committee. Higgs was only a minor lobbyist from the viewpoint of the network operations (although he clearly worked for the tobacco industry in other ways)
Higgs received his Ph.D. in economics from Johns Hopkins University, and he has taught at the University of Washington, Lafayette College, Seattle University, and the University of Economics, Prague. He has been a visiting scholar at Oxford University and Stanford University, and a fellow for the Hoover Institution and the National Science Foundation.
"Dr. Higgs is the editor of The Independent Institute books The Challenge of Liberty, Re-Thinking Green, Hazardous to Our Health? and Arms, Politics, and the Economy, plus the volume Emergence of the Modern Political Economy.
He is both an economic historian and libertarian economist who combines material from the GMU Public Choice Society, the New Institutional economics, and the Austrian Hayek/Mises school of economics. In general he promotes an extreme form of free-market deregulations, in political, legal theory and public policy.
"His authored books include Neither Liberty Nor Safety, Depression, War, and Cold War; Politická ekonomie strachu (The Political Economy of Fear, in Czech), Resurgence of the Warfare State; Against Leviathan, The Transformation of the American Economy 1865-1914; Competition and Coercion, and Crisis and Leviathan. A contributor to numerous scholarly volumes, he is the author of more than 100 articles and reviews in academic journals.
"Dr. Higgs has spoken at more than 100 colleges and universities and at the meetings of such professional organizations as the Economic History Association, Western Economic Association, Population Association of America, Southern Economic Association, International Economic History Congress, Public Choice Society, International Studies Association, Cliometric Society, Allied Social Sciences Association, American Political Science Association, American Historical Association, and others." 
The question is how many of these articles were written for poisoning and polluting corporations and industry advocacy organisations. We know that a significant number were written for the tobacco industry.
