The public choice sedition: variations on the theme of scientific warfare

Given a significant element of truth in "Public Choice", a modest element must be found when a similar approach is made to the behavior of economic scientists. Harry Johnson found this in "The Keynesian Revolution and the Monetarist Counter-Revolution". Following him, I find more in the Public Choice "Revolution" itself. The basic visions, assumptions and methods of the latter are appraised within its time-space stream. "Variations on a theme by Buchanan" or "The B- and F-Twist" could have been suggestive subtitles for this paper -- an embrycnic Economics of Knowledge, a complement to the Sociology of Knowledge.

Fronteiras da nova economia institucional

These papers deal with some main topics in new institutional economics. I make a survey of the literature, considering the contributions presented by Buchanan, Tullock, Coase, Olson and North to modern approaches to political economy. In fact, the first article is very simple. It should be used as support material in economics seminars at undergraduated level. The second one is an academic paper and deals basically with the contributions of public choice theory to the political understanding.
