Varieties of Capitalism and Institutional Complementarities in the Macroeconomy: An Empirical Analysis

Using aggregate analysis, this paper examines the core contentions of the “varieties of capitalism” perspective on comparative capitalism. We construct a coordination index to assess whether the institutional features of liberal and coordinated market economies conform to the predictions of the theory. We test the contention that institutional complementarities occur across sub-spheres of the macroeconomy by examining the correspondence of institutions across sub-spheres and estimating the impact of complementarities in labor relations and corporate governance on rates of growth. To assess the stability of the institutional features central to the theory, we assess the dynamics of institutional change in recent years. The evidence suggests that there are powerful interaction effects among institutions across sub-spheres of the political economy that must be considered if the economic impact of institutional change in any one sphere is to be accurately assessed.Mit Hilfe von Aggregatdaten analysiert dieses Papier Kernaussagen des "Varieties-of-Capitalism"-Ansatzes. Um beurteilen zu können, ob die Aussagen der Theorie mit den institutionellen Begebenheiten liberaler und koordinierter Ökonomien übereinstimmen, konstruieren wir einen ländervergleichenden Index der ökonomischen Koordination. Wir überprüfen die These von der institutionellen Komplementarität zwischen den verschiedenen Sphären politischer Ökonomien, indem wir das Zusammenwirken von Institutionen analysieren und den Einfluss komplementärer Institutionen der Arbeitsbeziehungen und der Unternehmenskontrolle auf die Höhe von Wachstumsraten untersuchen. Wir diskutieren darüber hinaus, wie stabil die institutionellen Begebenheiten in den vergangenen Jahren waren. Im Ergebnis zeigen sich starke Interaktionseffekte zwischen den Sphären politischer Ökonomien, die berücksichtigt werden müssen, um die wirtschaftlichen Wirkungen institutionellen Wandels in einzelnen Sphären zu verstehen.1 The varieties of capitalism approach 2 Establishing coordination as a crucial dimension 3 Locating political economies relative to one another 4 Congruence across spheres of the political economy 5 The effect of institutional complementarities on economic growth 6 Political and economic adjustment paths 7 Conclusion Reference

Practicing mentorship: Graduate-student supervision of undergraduate research assistants

Many research universities rely on graduate students to supervise undergraduate research assistants (RAs) who collect data and handle research logistics. This experience can be mutually beneficial, as RAs receive hands-on learning, and graduate students practice mentorship in preparation for assuming a faculty role. However, assistantships must be intentionally designed to meet educational (not just practical) goals. What training and support do graduate students receive to take on this mentorship role? In two surveys, RAs reported on their satisfaction, educational benefit, and desired changes; while graduate students reported on their goals, challenges, and the support they receive

New early Eocene tapiromorph perissodactyls from the Ghazij Formation of Pakistan, with implications for mammalian biochronology in Asia

Early Eocene mammals from Indo-Pakistan have only recently come under study. Here we describe the first tapiromorph perissodactyls from the subcontinent. Gandheralophus minor n. gen. and n. sp. and G. robustus n. sp. are two species of Isectolophidae differing in size and in reduction of the anterior dentition. Gandheralophus is probably derived from a primitive isectolophid such as Orientolophus hengdongensis from the earliest Eocene of China, and may be part of a South Asian lineage that also contains Karagalax from the middle Eocene of Pakistan. Two specimens are referred to a new, unnamed species of Lophialetidae. Finally, a highly diagnostic M3 and a molar fragment are described as the new eomoropid chalicothere Litolophus ghazijensis sp. nov. The perissodactyls described here, in contrast to most other mammalian groups published from the early Eocene of Indo-Pakistan, are most closely related to forms known from East and Central Asia. Tapiromorpha are diverse and biochronologically important in the Eocene there and our results allow the first biochronological correlation between early Eocene mammal faunas in Indo-Pakistan and the rest of Asia. We suggest that the upper Ghazij Formation of Pakistan is best correlated with the middle or late part of the Bumbanian Asian Land-Mammal Age, while the Kuldana and Subathu Formations of Pakistan and India are best correlated with the Arshantan Asian Land-Mammal Age

Inbreeding in the coffee berry borer, Hypothenemus hampei (Coleoptera : Scolytidae) estimated from endosulfan resistance phenotype frequencies

An estimate of the inbreeding coefficient, Fis, of the coffee berry borer, #Hypothenemus hampei Ferrari, was calculated from genotype frequencies of endosulfan resistance in beetles collected from berries in 41 fields on the East Coast of New Caledonia. Two different estimates were obtained as a function of sampling date : Fis = 0,491 + ou - 0,059 (s.e.) for samples collected in September, and Fis = 0,215 + ou - 0,108 for samples collected in April. These values of Fis are very high in comparison to those of more insects, but surprisingly low given current understandings of #H. hampei mating patterns. The difference between April and September Fis estimates is discussed in terms of insecticide regimes and seasonal variability of sib inbreeding levels. The high level of inbreeding in the coffee berry borer increases frequencies of homozygotes relative to heterozygotes. Inbreeding will accelerate resistance evolution whenever the fitness of homozygous resistant insects exceeds that of heterozygotes, and will undermine any high - dose strategy to control resistance evolution.

Quenched growth of nanostructured lead thin films on insulating substrates

Lead island films were obtained via vacuum vapor deposition on glass and ceramic substrates at 80 K. Electrical conductance was measured during vapor condensation and further annealing of the film up to room temperature. The resistance behavior during film formation and atomic force microscopy of annealed films were used as information sources about their structure. A model for the quenched growth, based on ballistic aggregation theory, was proposed. The nanostructure, responsible for chemiresistive properties of thin lead films and the mechanism of sensor response are discussed.Comment: 2 figures; accepted to Thin Solid Film
