An Econometric Analysis of the Role of Knowledge in Economic Performance

We conduct a regression analysis of the effects of knowledge on aggregate economic performance using data from the United Nations Development Program (UNDP) and the World Bank for four groups of countries during 1995–2001. Our results indicate that knowledge is a key driver of economic growth for each group of countries. More importantly, we find that variation in economic performance among these groups may be related to the timing of investment in education, R&D, and information technology, as well as economic policies that affect trade and foreign direct investment.     

TRAJECTORIES OF CRIME AT PLACES: A LONGITUDINAL STUDY OF STREET SEGMENTS IN THE CITY OF SEATTLE*

Studies of crime at micro places have generally relied on cross‐sectional data and reported the distributions of crime statistics over short periods of time. In this paper we use official crime data to examine the distribution of crime at street segments in Seattle, Washington, over a 14‐year period. We go beyond prior research in two ways. First, we view crime trends at places over a much longer period than other studies that have examined micro places. Second, we use group‐based trajectory analysis to uncover distinctive developmental trends in our data. Our findings support the view that micro places generally have stable concentrations of crime events over time. However, we also find that a relatively small proportion of places belong to groups with steeply rising or declining crime trajectories and that these places are primarily responsible for overall city trends in crime. These findings are particularly important given the more general decline in crime rates observed in Seattle and many other American cities in the 1990s. Our study suggests that the crime drop can be understood not as a general process that occurred across the city landscape but one that was generated in a relatively small group of micro places with strong declining crime trajectories over time.

Implementing Democratic Equality in Political Parties: Organisational Consequences in the Swedish and the German Pirate Parties

This article theorises and empirically assesses some important intra‐organisational implications of maximising democratic equality in political parties both between followers and members and between members and elites. They include weak member commitment, passivity of the rank‐and‐file membership and – depending on party structure – high levels of internal conflict. To substantiate the arguments, two parties that implement principles of democratic equality in their organisations are examined: the Swedish and German Pirate parties. These cases show, first, that while organisational structures implementing norms of equality allowed them to rapidly mobilise a considerable following, the same structures systematically reduced their capacity to consolidate support in the longer term – a weakness that might eventually put these parties' survival at risk. Second, they show that differences in the extent to which subnational units provide a foundation for member mobilisation helps to explain variation in the level of internal conflict experienced by these parties.
