Software is a potentially excludable public good. It is possible, at some cost, to exclude non-paying users from its consumption by using copyright law or technological restraints. Licensing the software under proprietary license terms makes of it a private good, licensing it under the BSD does...

Conviction rates in Japan exceed 99 percent -- why? On the one hand, because Japanese prosecutors are badly understaffed they may prosecute only their strongest cases and present judges only with the most obviously guilty defendants. On the other, because Japanese judges can be reassigned by the...

The paper analyzes voluntary Free Software/Open Source Software (FS/OSS) organization of work. The empirical setting considered is the Debian GNU/Linux operating system. The paper finds that the production process is hierarchical notwithstanding the modular (nearly decomposable) architecture of...

It has been argued that collusion among the members of an organization or a vertical structure creates efficiency losses, and hence should be prevented. This paper shows that whenever collusion takes the form of co-insurance agreements, here called `friendships', among the members of a vertical...

This paper shows how fixed costs can play an important role in determining the structure of organizations. Applications considered include layoffs, downsizing, heterogeneity among firms, and the structure of hierarchies. Agency problems as a source of fixed costs are also considered.

External agents are frequently characterized as necessary for efficiency in team production settings. At the same time, these agents must be constrained from opportunistically exercising their enforcement capabilities. I argue that collective action costs and formal institutions (e.g., golden...

This paper analyses market competition between two different types of credit card platforms: not-for-profit associations and proprietary systems. The main focus is on the role of the interchange fee set by not-for-profit platforms. We show that when the interchange fee is set so as to maximise...

A fundamental aspect of any open payment system is the interchange fee that is paid from the merchant's bank to the cardholder's bank. Using a model in which there is partial participation by heterogeneous consumers and merchants, this paper characterizes the output maximizing, profit maximizing...

This paper analyses oligopolies using the Cournot/Stackelberg framework, but allowing some firms to be pursueing aims other than profit maximisation. The existence of even a single output maximising firm can have dramatic effects on outputs, prices and welfare, even if such a firms faces...
