Segmental new-product diffusion of residential broadband services

Aggregate models of innovation diffusion do not capitalise on valuable consumer adoption dynamics that may be useful to policy makers and market planners. The non-diffusion choice literature shows quite clearly that these dynamics may indeed be very important factors in the diffusion process. The authors present a segmental broadband diffusion model that is estimated from consumer survey data that measure the effect that household income has on its propensity to adopt this technological product. The results suggest that early broadband adopters are mostly made up from wealthy households and only as time progresses do less well off households adopt. The findings presented in this paper will be important to market planners and policy makers requiring a relatively simple technique that forecasts segmental innovation diffusion.     

Addressing the Growing Inadequacies of the <Emphasis Type="Italic">Ellerth</Emphasis>/<Emphasis Type="Italic">Faragher</Emphasis> Affirmative Defense: Fashioning a Sensible and Feasible Solution

Public policy seeks an equitable balance between the rights and duties of both employers and employees in creating a workplace free of sexual harassment. This goal is particularly difficult to achieve when supervisors create a hostile work environment. The U.S. Supreme Courts decisions in Ellerth and Faragher created an affirmative defense against vicarious liability for employers, but subsequent applications of these rulings have been inconsistent and problematic. Courts and legislators need to (1) choose the appropriate standard of employer liability for sexual harassment committed by supervisors, and (2) decide what, if any, defenses are available to employers when employees bring claims of sexual harassment. We conclude that holding employers strictly liable while allowing for the limitation of damages based on avoidable consequences, as recently adopted by the California Supreme Court in McGinnis, is preferable to other liability standards and defenses.     

Selection institutions and war aims

We explore how the sizes of the winning coalition and selectorate influence the war aims of states. Leaders who answer to a small winning coalition are more likely to seek territorial gain as a way to increase state resources. Nonterritorial war aims produce a commitment problem in that after the war the defeated state may not comply with the victor's demands. States with large winning coalitions are more willing to continue the war to remove the enemy leader as a solution to this commitment problem. We test our hypotheses against the Militarized Interstate Dispute data set, and we find some support for our argument. Received: June 2004, Accepted: April 2005, Correspondence to: James D.

Leader Survival and Cabinet Change

Political leaders face both internal and external threats to their tenure as leaders. To retain office leaders need mass support, for instance to win elections. However, they also need to deal with potential internal party rivals. Using a game theoretic model, we examine how the incentives created by these competing pressures affect the retention of ministers across different political systems. Since non‐democratic leaders face relatively little threat from the masses, their concern is to reduce internal party risk. Therefore, they remove high performing ministers and retain mediocre and poor performers. As it becomes easier for the masses to replace the party in power, leaders must tradeoff internal and external threats. Retaining competent leaders improves party performance but generates an internal party rival.     

EVALUATING THE CRITICISMS OF FAIR TRADE1

This article critically examines some of the most common arguments used to support the view that Fair Trade should be rejected by consumers and businesses seeking to socialise their economic decisions. Overall the paper finds that the majority of such criticisms lack evidential rigour and sophisticated theory but instead rely on a high degree of rhetorical aptitude. While this does not naturally lead to the position that Fair Trade is necessarily beneficial, the conclusion reflects on a substantial amount of positive evidence to suggest that Fair Trade should not be abandoned by consumers or businesses.
