Techniques for evaluating regulatory change

This paper demonstrates the applicability of two empirical techniques—the Heckman two-stage switching regression and the event study methodology—for evaluating regulatory or legislative change relating to companies and in particular to the regulation of company reporting. These techniques measure the impact of regulatory changes once they have happened. They could be used in practice if regulatory changes were subject to a review procedure. The availability of these relatively sophisticated techniques should encourage the quantitative analysis of regulatory changes. Comparisons of effects across member states of the European Union would be interesting but would obviously need care.     

Temporary migration in Shanghai and Beijing

In a number of developing countries, temporary migration plays a key role in the labor market. In China, where permanent migration is carefully controlled, movement without an official change in household registration (temporary migration) is relatively unrestricted. It has increased dramatically since the economic reforms introduced in 1979. Using data from surveys in Shanghai and Beijing, this article focuses on the sociodemographic characteristics of temporary migrants in relation to their reasons for moving and the duration of their stay at destination. Many temporary migrants come to these cities in search of work; however, many others move for noneconomic reasons associated with family reunion and retirement. Moreover, the distinctive socioeconomic features of Shanghai and Beijing also influence the characteristics of temporary migrants and their reasons for coming to the cities.

Staying Cool Across the First Year of Middle School

As students transition into middle school they must successfully negotiate a new, larger peer context to attain or maintain high social standing. The goal of this study was to examine the extent to which the maintenance, attainment, and loss of a cool status over the course of the sixth grade is associated with student and classroom levels of physical, verbal, and relational aggression. To address this goal, we studied a sample of 1985 (55% girls) ethnically diverse adolescents from 99 sixth grade classrooms in the United States. Attaining a cool status at any point across the school year was associated with stronger aggressive reputations. Additionally, classroom norms for aggressive behavior moderated the association between changes in aggression over the school year and the stability of coolness such that students who maintained their coolness across the school year showed greater increases in their verbally aggressive reputations from fall to spring when they were in classrooms with higher levels of aggression. The findings illustrate the importance of fitting in with social norms for maintaining a high social status among a new set of peers in middle school.     

If Brain Scans Really Detected Deception,Who Would Volunteer to be Scanned?

Abstract: Recent neuroimaging studies investigating the neural correlates of deception among healthy people, have raised the possibility that such methods may eventually be applied during legal proceedings. Were this so, who would volunteer to be scanned? We report a “natural experiment” casting some light upon this question. Following broadcast of a television series describing our team’s investigative neuroimaging of deception in 2007, we received unsolicited (public) correspondence for 12 months. Using a customized template to examine this material, three independent assessors unanimously rated 30 of an initial 56 communications as unequivocally constituting requests for a “scan” (to demonstrate their author’s “innocence”). Compared with the rest, these index communications were more likely to originate from incarcerated males, who were also more likely to engage in further correspondence. Hence, in conclusion, if neuroimaging were to become an acceptable means of demonstrating innocence then incarcerated males may well constitute those volunteering for such investigation.     

A Feminist Perspective on Contract Theories from Law and Economics

This article offers a feminist perspective on contract theories in law,economics and law-and-economics. It identifies masculine traits presentcontract theories in all three disciplines. It then describes andassesses some developments that appear to be feminising: Therecognition of the importance of social norms in contract theory andtheories of contract as relationship. The article's main claim is that amasculine model of decision-making persists even within the less overtlymasculine models of contract. The problem of sexually transmitted debtresulting from a surety contract is analysed in detail as a specificexample supporting the article's general argument. The article concludesthat the way forward is to be found in a recognition of other ways ofmaking decisions.
