Multiple principals want to obtain income from a privately informed agent and design their contracts non-cooperatively. The degree of coordination between principals shapes the contracts and affects the amount of monitoring. Equity-like contracts and excessive monitoring emerge when principals coordinate or verify each others’ monitoring efforts. When this is not possible, free riding weakens m...

We consider a class of dynamic collective action problems in which either a single principal or two competing principals vie for the support of members of a group. We focus on the dynamic problem that emerges when agents negotiate and commit their support to principals sequentially. A danger for the agents in this context is that a principal may be able to succeed by exploiting competition amon...

School leaders are key factors in implementation of information and communication technology (ICT) in schools. They need to understand the capacities of the new technologies, to have a personal proficiency in their use, and be able to promote a school culture which encourages exploration of new techniques in teaching, learning and management. However, there is less information about the current...

We analyze the interaction of explicit and implicit contracts in a model with selfish and fair principals. Fair principals are willing to honor implicit agreements, whereas selfish principals are not. Principals are privately informed about their types. We investigate a separating equilibrium in which principals reveal their type through the contract offer to the agent. If this equilibrium is p...

The purpose of this study was to examine principals' perceptions and practices regarding bullying prevention. A survey instrument was developed to assess principals' stages of change and perceived barriers regarding selected bullying prevention activities as well as the effectiveness of bullying prevention activities. Of a national random sample of 700 principals to which the survey was mailed,...

This report summarizes the results of the Illinois Education Research Council’s (IERC) survey with Illinois principals conducted in November 2010. The purpose of the survey, and of this report, is to help researchers, policymakers, and practitioners better understand the work that Illinois principals do and their preferences and priorities regarding this work. We received responses from 877 par...

This paper argues that the publishing of academic research by and large belongs to the public sector domain, and that the scientific knowledge stemming from the public sectors is important for innovation. In 2004 the Norwegian Association of Higher Education Institutions (UHR) introduced an incentive based system in which academic institutions receive economic compensation as a function or thei...

Programs are often structured around the idea that different pieces of code comprise distinct principals, each with a view of its environment. Typical examples include the modules of a large program, a host and its clients, or a collection of interactive agents. In this paper, we formalize this notion of principal in the programming language itself. The result is a language in which intuitive s...

A school principal’s role is a complex mix of leadership and administration, geared toward enabling and motivating school staff to provide the best possible opportunities for student growth and achievement. School principals face many challenges, especially in their first year at a school, when they must function effectively in a new environment and assimilate quickly to a new culture. Furtherm...
