Public capital stock and interstate variations in manufacturing efficiency

This study focuses on the role of public capital stock in contributing to interstate differences in productive efficiency in manufacturing. Our motivation is to assess the role of public capital as a source of persistent regional variations in efficiency, and thus determine if public infrastructure policies might reasonably be expected to alter the competitive environment of a state's manufacturing sector. We use a stochastic frontier production function model, explicitly incorporating infrastructure capital, to examine the relative performance of the aggregate manufacturing sector across states and over time. We calculate an index of productive efficiency and estimate the determinants of statewide variations in it. These results show that variations in per capita infrastructure stocks significantly affect manufacturing efficiency. Considering the behavior of public capital as both a direct and an indirect input furthers our understanding of the role of infrastructure and its implications for regional economic development policies.     

Metrological framework for selecting morphological characters to identify species and estimate developmental maturity of forensically significant insect specimens

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

• Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
• Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
• These metrological principles also apply to individuation of unique objects in general.

     

Power and changing modes of governance in the euro crisis

Which European Union actors are most powerful in the governance of the euro crisis? The euro crisis has reignited the classic debate between intergovernmentalists, who tend to stress the coercive power of dominant member states in the European Council, and supranationalists, who maintain that through the use of institutional power, the Commission, and the European Central Bank turned out the “winners” of the crisis. This article argues that euro crisis governance is best understood not just in terms of one form of power but instead as evolving through different constellations of coercive, institutional, and ideational power that favored different EU actors over the course of the crisis, from the initial fast‐burning phase (2010–2012), where the coercive and ideational power of Northern European member states in the European Council was strongest, to the slow‐burning phase (2012–2016), when greater influence was afforded supranational actors through the use of ideational and institutional power.     

The political economy of churches in Denmark, 1300–2015

This paper reports new time-series for the numbers and sizes of churches in Denmark over a 715-year period. Per capita, the new series are termed church densities. A pattern emerges in the series that corresponds to the main development in the economy: until 1750, the economy was in the traditional steady state, where church densities were high and did not decline substantially. Modern development set in after 1750. Since then, church densities have declined more than five times. Moreover, capacity utilization of church rooms has declined, which means that the reduction in the demand for churches must have been even larger. We argue that this large decline is caused by a fall in religiosity that is caused by economic development as measured by the rise in incomes. In parallel with similar transitions in other sectors, e.g., the Agricultural Transition, it is termed the Religious Transition.
