Why is there a seniority system? To solve an agency problem

It is generally recognized that principals and agents both have an incentive to minimize shirking, and that this is often accomplished by entering into long term relationships in which the agent is offered rewards that increase with seniority. This paper considers that the congressional seniority system may exist as a means of insuring that representatives (agents) are faithful to the demands of constituents (principals). The unique feature of the seniority system, that tenure is rewarded with increasing power rather than increasing pay, is explained as a consequence of the need for each group to make credible commitments to the other. Rules changes adopted by the House of Representatives in the mid 1970s are used to test the impact of alternative rules on election outcomes.I wish to thank Mark Crain, Thomas Fomby, John Lott and Philip Porter for their comments.     

The political economy of dissonance

Cognitive dissonance is defined as the psychological discomfort or annoyance that may exist when an individual's choice is not consistent with his values and beliefs. Dissonance may cause an individual to reconsider his values and beliefs, enter new choices with different parameters, respond to the constraints imposed, or change his individual preference function. This paper extends Festinger's (1957) theory of cognitive dissonance to the work of public choice theorists and seeks to explain the incentives of the iron triangle to foment and quell dissonance. Examples are provided for specific environmental and health and safety risks. Akerlof and Dickens (1983) used cognitive dissonance to justify public sector intervention as necessary to correct what they perceived as a market failure in the choice of safety equipment by workers in hazardeus industries. Unlike Akerlof and Dickens (1983), we argue that the concept of cognitive dissonance is applicable to the analysis of public sector decisions giving rise to government failure as well as private decisions involving possible market failure. This paper views the public sector as a market-like arrangement in which dissonance may be produced and exchanged like any other commodity. Cognitive dissonance provides a useful framework for examining individual choice and also expands our understanding of the unseen elements of rent-seeking.     

WATERPOWER AND WILDERNESS: POLITICAL AND ADMINISTRATIVE ASPECTS OF THE LAKE PEDDER CONTROVERSY

Not that even the truth was easy to discover: different eye-witnesses give different accounts of the same events, speaking out of partiality for one side or the other or else from imperfect memories.     

Development of a DNA-based macroarray for the detection and identification of Amanita species

A DNA-based macroarray was designed to quickly and accurately identify certain Amanita mushroom specimens at the species level. The macroarray included probes for Amanita phalloides and Amanita ocreata, toxic species responsible for most mushroom poisonings, and Amanita lanei and Amanita velosa, edible species sometimes confused with toxic species, based on sequences of the highly variable internal transcribed spacer (ITS) region of rDNA. A cryptic species related to A. ocreata and one related to A. lanei, identifiable by ITS sequences, were also included. Specific multiple oligonucleotide probes were spotted onto nylon membranes and the optimal hybridization temperatures were determined. The Amanita DNA array was highly specific, sensitive (0.5 ng DNA/μL and higher were detected), and reproducible. In two case studies, the method proved useful when only small amounts of mushroom tissue remained after a suspected poisoning. An identification could be completed in 12 h.     

Human Rights in US Courts: Alien Tort Claims Act Litigation after Sosa v. Alvarez-Machain

In Filartiga v. Pena-Irala (1980), the Second Circuit Court of Appeals ruled that victims of human rights violations could sue their oppressors civilly in US courts under an eighteenth century law now called the Alien Tort Claims Act (ATCA). Controversy raged over the Filartiga decision and the proper interpretation of the ATCA for 24 years. Then in Sosa v. Alvarez-Machain (2004), the Supreme Court issued its first ATCA decision. This essay analyzes the effect of the Sosa decision on the development of human rights law in US courts. I find that while the federal judiciary is responding to some of the Supreme Court’s directives, lower courts still retain a great deal of discretion in handling ATCA cases.

Federalizing energy? Agenda change and the politics of fracking

This paper focuses on agenda change affecting the politics of ??fracking operations?? in the US, a process of extracting natural gas from underground shale formations. We examine how the movement of this policy issue between the state and federal levels of government has become increasingly contentious because of rising public concern about pollution impacts. Using information obtained from documentary sources and media content analysis, we found that the natural gas policy coalition has largely focused on a political strategy based on maintaining fracking regulatory controls at the state level, while the environmental policy coalition has pushed for increased regulation of drilling practices in general, including a larger policy and oversight role for federal agencies such as EPA.
