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.

The market of academic journals : empirical evidence from data on French libraries

This paper analyzes the demand and cost structure of the French market of academic journals, taking into account its intermediary role between researchers, who are both producers and consumers of knowledge. This two sidedness feature will echoes similar problems already observed in electronic markets – payment card systems, video game console etc - such as the chicken and egg problem, where readers won’t buy a journal if they do not expect its articles to be academically relevant and researchers, that live under the mantra “Publish or Perish”, will not submit to a journal with either limited public reach or weak reputation. After the merging of several databases, we estimate the aggregated nested logit demand system combined simultaneously with a cost function. We identify the structural parameters of this market and find that price elasticities of demand are quite large and margins relatively low, indicating that this industry experiences competitive constraints.
