I came across this and, understanding that there are many undergrads here who may be interested in such a contest, will just leave this here:
The Society for the Advancement of Austrian Economics is pleased to announce the third annual Carl Menger Essay Contest. The purpose of the contest is to recognize and encourage undergraduate scholarship in the Austrian tradition and the broadly catallactic approach to social science which it represents, an approach common also to the Scottish Enlightenment of Smith and Hume, the French Liberal School of Say and Bastiat, the Virginia School of Buchanan and Tullock, the UCLA price theory of Alchian and Demsetz, and the Bloomington School of Vincent and Elinor Ostrom, among others. We invite essays that explore, advance, challenge, or apply the ideas of these and related schools of thought.
The catallactic approach emphasizes exchange and the rules in which exchange takes place. See especially Jame’s Buchanan’s “What Should Economists Do?” (requires JSTOR access). Also helpful are Richard Wagner’s discussion of value vs. exchange and Peter Boettke’s distinction between “mainline” and mainstream economics.
Good luck to all so inclined!
NOTE: The fourth link provided in the above excerpt (regarding Boettke’s distinction) is dead; here is the article to which the hypertext is intended to link: Liberty vs. Power in Economic Policy in the 20th and 21st Centuries
