Quantifying the Contours of Power: Chief Justice Roberts & Justice Kennedy in Criminal Justice Cases

This Article seeks to contribute to the debate with an empirical analysis of voting behavior in criminal justice cases decided during the first ten Terms of the Roberts Court era. The following section presents the study’s case selection and introduces the types of measures used to illuminate influence on the High Court (Part II). Court- and individual-level tendencies (Part III) identify potential spheres of influence occupied by Chief Justice Roberts and Justice Kennedy. These bases of judicial power are examined separately in Part IV (Chief Justice Roberts) and Part V (Justice Kennedy). Some possible implications of Justice Scalia’s death on these power bases are addressed in Part VI

The significance of distance constraints in peasant farming systems with special reference to sub-Saharan Africa

Analysis of agricultural development potential at village level tends to neglect the factor of relative location, compared with the attention paid to physical resources and economic factors. This paper argues that, in African peasant agriculture, distance takes on increasing significance when farming populations are resettled and agglomerated, there being little intensification in evidence. The impacts of agglomeration and excessive ‘journeys to work’ are identified as affecting the quantity and the quality of agricultural labour inputs, the collection of domestic necessities (especially fuelwood), livestock husbandry, and socio-cultural and welfare conditions.\ud \ud Some simple analyses of time-distance relations, such as the ‘effective working day’, are also described, and a model of peasant decision-making with respect to optimizing farm activity location is proposed as a descriptive-explanatory tool. Response to distance problems is considered as part of rural change; and the particular position of peasant women vis-à-vis distance and transport technology is stressed. Data collection methods and descriptive statements of the spatial relationships within a village, or an agro-ecological zone, are outlined within the framework of rapid rural appraisal. Finally, a number of potential solutions to the agro-economic distance problem are briefly discussed—either as changes in farming systems, or as redistributions of the working population. Changes with the greatest potential are intensification and satellite settlements, though both face difficulties in policy and in implementation

Estimation Methods for Duration Models

This paper is a selected overview of econometric methods for duration models and will appear in the forthcoming book The Economics of Search by the authors. The focus of the paper is on martingale methods for continuous time data and general methods for the analysis of discretetime data including multi-spell models and general life-history models.
