ENDOGENOUS PRESIDENTIALISM

We develop a model to understand the incidence of presidential and parliamentary institutions. Our analysis is predicated on two ideas: first, that minorities are relatively powerful in a parliamentary system compared to a presidential system, and second, that presidents have more power with respect to their own coalition than prime ministers do. These assumptions imply that while presidentialism has separation of powers, it does not necessarily have more checks and balances than parliamentarism. We show that political leaders who prefer presidentialism may be supported by their own coalition if they fear losing agenda‐setting power to another group. We argue that the model is consistent with a great deal of qualitative information about presidentialism in Africa and Latin America. (JEL: D72, P5, O1)     

Gendered forms of responsibility and control in teenagers' views of alcohol

There has been a shift in the most recent UK Government's Alcohol Strategy (2012) from personal responsibility towards a model of shared responsibility for young people's drinking. On closer examination of the strategy, however, it appears that rather than exonerating young people from blame, governance is merely extended to include wider partners. Using findings from nine focus groups with young people in Liverpool, UK, we explore who they believe are responsible for their drinking behaviours and how they learn to become ‘good drinkers’. Our findings show that while teenagers were aware of dominant alcohol-related messages and maintained a moral position as responsible citizens; they also negotiated and resisted norms about teenage drinking. Although both boys and girls agreed that parents were the primary responsible authority for regulating their drinking, there was gendered disagreement about personal responsibility. The girls described how they were ultimately responsible for any adverse consequences if they drank too much whilst the boys considered a wide range of partners who would be implicated. However, unlike the girls, the boys described a willingness to either abstain or moderate their alcohol intake in order to remain in control and avoid any alcohol-related trouble or harm.

Behavioral Economics and Regulatory Analysis

Behavioral economics has captured the interest of scholars and the general public by demonstrating ways in which individuals make decisions that appear irrational. While increasing attention is being focused on the implications of this research for the design of risk‐reducing policies, less attention has been paid to how it affects the economic valuation of policy consequences. This article considers the latter issue, reviewing the behavioral economics literature and discussing its implications for the conduct of benefit‐cost analysis, particularly in the context of environmental, health, and safety regulations. We explore three concerns: using estimates of willingness to pay or willingness to accept compensation for valuation, considering the psychological aspects of risk when valuing mortality‐risk reductions, and discounting future consequences. In each case, we take the perspective that analysts should avoid making judgments about whether values are “rational” or “irrational.” Instead, they should make every effort to rely on well‐designed studies, using ranges, sensitivity analysis, or probabilistic modeling to reflect uncertainty. More generally, behavioral research has led some to argue for a more paternalistic approach to policy analysis. We argue instead for continued focus on describing the preferences of those affected, while working to ensure that these preferences are based on knowledge and careful reflection.     

Adolescent Socialization in Rural Appalachia: The Perspectives of Teens,Parents, and Significant Adults

ABSTRACT

The purpose of this qualitative study was to explore the social networks of Appalachian adolescents to understand socialization strategies and goals. A total of 46 interviews were conducted with five families (mothers, fathers, and adolescents) and 11 socialization agents the families identified as exerting significant influence in the lives of the adolescents. Interviews were transcribed and then analyzed using principles of grounded theory. Five themes developed from the interviews: the importance of community to the socialization process, adult involvement and support, adolescent monitoring, teaching respect and responsibility, and adolescent autonomy. Results suggest the need for in-depth investigation of adolescent development within a variety of cultural and social contexts to more fully understand these processes.     

STOCHASTIC KINETIC MODELS: DYNAMIC INDEPENDENCE, MODULARITY AND GRAPHS

The dynamic properties and independence structure of stochastic kinetic models (SKMs) are analyzed. An SKM is a highly multivariate jump process used to model chemical reaction networks, particularly those in biochemical and cellular systems. We identify SKM subprocesses with the corresponding counting processes and propose a directed, cyclic graph (the kinetic independence graph or KIG) that encodes the local independence structure of their conditional intensities. Given a partition [A, D, B] of the vertices, the graphical separation A ⊥ B|D in the undirected KIG has an intuitive chemical interpretation and implies that A is locally independent of B given A ∪ D. It is proved that this separation also results in global independence of the internal histories of A and B conditional on a history of the jumps in D which, under conditions we derive, corresponds to the internal history of D. The results enable mathematical definition of a modularization of an SKM using its implied dynamics. Graphical decomposition methods are developed for the identification and efficient computation of nested modularizations. Application to an SKM of the red blood cell advances understanding of this biochemical system.
