Occupational structure is commonly viewed as either hierarchical or organized around stable classes. Yet, recent studies have proposed to describe occupational structure as a network, where the mobility of workers demarcates boundaries. Moving beyond boundary detection, this article develops occupational network as a dynamic system in which between-occupation exchange is shaped by occupational similarities, and occupational attributes are in turn responsive to mobility patterns. We illustrate this perspective with the exchange networks of detailed occupations. Our analysis shows that the U.S. occupational structure has become more fragmented. The division was in part associated with the emerging importance of age composition, as well as those of quantitative, creative, and social tasks. The fragmentation reduced wage contagion and therefore contributed to a greater between-occupation wage dispersion. These results indicate that occupational attributes and mobility are co-constitutive, and that a network perspective provides a unifying framework for the study of stratification and mobility.

Abstract Which type of work do Italians perform? In this contribution, we aim at detecting the anatomy of the Italian occupational structure by taking stock of a micro-level dataset registering the task content, the execution of procedures, the knowledge embedded in the work itself, called ICP (Indagine Campionaria sulle Professioni), the latter being comparable to the U.S. O*NET dataset. We perform an extensive empirical investigation moving from the micro to the macro level of aggregation. Our results show that the Italian occupational structure is strongly hierarchical, with the locus of power distinct by the locus of knowledge generation. It is also weak in terms of collaborative and worker involvement practices, and possibility to be creative. Our analysis allows to pinpoint the role exerted by hierarchical structures, decision-making autonomy, and knowledge as the most relevant attributes characterizing the division of labor.

This paper compares the occupational structure of cities in Brazil and United States aiming to evaluate the extent to which the economic structure of these urban agglomerations is associated with the different stages of development, specifically when comparing a rich country with a developing one. Using a harmonized occupational database and microdata from the Brazilian 2010 Demographic Census and the U.S. American Community Survey (2008-2012), results show that Brazilian cities have a stronger connection between population size, both with occupational structure and human capital distribution, than the one found for cities in the United States. These findings suggest a stronger primacy of large cities in Brazil’s urban network and a more unequal distribution of economic activity across cities when compared to USA, indicating a strong correlation between development and occupational structure.

Maize agriculture was practiced in the U.S. Southwest slightly before 2000 B.C., but had a negligible impact on population growth rates until the development or introduction of more productive landraces; the ability to successfully cultivate maize under a greater variety of conditions, with dry farming especially important; the addition of beans, squash, and eventually turkey to the diet; increased sedentism; and what we infer to be the remapping of exchange networks and the development of efficient exchange strategies in first-millenium-A.D. villages. Our estimates of birthrates and growth rates are derived from the proportions of immature individuals among human remains. These proportions are somewhat affected by warfare in our region, and perhaps also by climate. Nevertheless, there is a strong identifiable Neolithic Demographic Transition signal in the U.S. Southwest in about the mid-first-millennium A.D. in most subregions, visible a few hundred years after the introduction of well-fired ceramic containers, and more or less contemporaneous with the first appearance of villages. Independent genetic data derived from the mitochondrial genomes of present-day indigenous populations of the Southwest are also consistent with the hypothesis that a major demographic expansion occurred 1,500-2000 years ago in the Southwest.

Ceramic Vessels

AbstractProtohistoric Ancestral Apache Dismal River groups (A.D. 1600–1750) participated in large exchange networks linking them to other peoples on the Plains and U.S. Southwest. Ceramic vessels made from micaceous materials appear at many Dismal River sites, and micaceous pottery recovered from the Central High Plains is typically seen as evidence for interaction with northern Rio Grande pueblos. However, few mineral or chemical characterization analyses have been conducted on these ceramics, and the term “micaceous” has been applied to a broad range of vessel types regardless of the form, size, or amount of mica in their pastes. Our recent analyses, including macroscopic evaluation combined with petrography and neutron activation analyses (NAA), indicate that only a small subset of Dismal River sherds are derived from New Mexico clays. The rest were likely manufactured using materials from Colorado and Wyoming. Seasonal mobility patterns may have given Dismal River potters the opportunity to collect mica raw materials as they traveled between the Central Plains and Front Range, and this has implications for the importance of internal Plains social networks during the Protohistoric and Historic periods.
