We provide a theory of the role of discretion in agency. We do so by extending the standard principal-agent framework to include complex information and trust. With these two new ingredients we find that: optimal agency contracts may be incomplete; they do not necessarily use all available,...

The fine art auction business has remained a duopoly over its 250 year history. The industry is dominated by Sotheby's and Christie's Inc. Curiously, neither competitor has been able to overtake the other by a notable margin despite the clear network effects of this platform business. As we...

We study individuals' behavior in an environment that is deterministic, but too complex to permit tractable deterministic representation. Under mild conditions, behavior is represented by a unique probabilistic model in which the agent's inability to think through all contingencies of the...

We study competitive interaction between two alternative models of digital content distribution over the Internet: peer-to-peer (p2p) file sharing and centralized client-server distribution. We present microfoundations for a stylized model of p2p file sharing where all peers are endowed with...

We present a model of bandwidth allocation in a stylized peer-to-peer file sharing network with s peers (sharers) who share files and download from each other and f peers (freeriders) who download from sharers but do not contribute files. Assuming that upload bandwidth is scarcer than download...

Existing models of the principal-agent relationship assume the agent works only under extrinsic incentives. However, many observed agency contracts take the form of a fixed payment. For such contracts to work, the principal must trust the agent to work in the absence of incentives. I show that...

The demise of Enron, the largest bankruptcy in United States history, raised fundamental questions about the role of trust in agency relationships. The corporate collapse cast doubts on trust relationships between investors and corporate managers, between investors and investment advisors and...

The competitiveness of a country is the result of the competitiveness of its firms. The competitiveness of firms is partly determined by how their business models interact with the environment to produce offerings with added value. This chapter contributes to the reflection on Catalonia's...

Katz and Shapiro (1985) study systems compatibility in settings with one-sided platforms and direct network externalities. We consider systems compatibility in settings with two-sided platforms and indirect network externalities to develop an explanation why markets with two-sided platforms are...
