In the name of the Father: marriage and intergenerational mobility in the United States, 1850-1930

This paper constructs a continuous and consistent measure of intergenerational mobility in the United States between 1850 and 1930 by linking individuals with the same first name across pairs of decennial Censuses. One of the advantages of this methodology is that it allows to calculate intergenerational correlations not only between fathers and sons, but also between fathers-in-law and sons-in-law, something that is typically not possible with historical data. Thus, the paper sheds light on the role of marriage in the intergenerational transmis- sion of economic status from a historical perspective. We find that the father-son correlation in economic status grows throughout the period, but is consistently lower than the correlation between fathers-in-law and sons-in-law. The gap declines over time, and seems to have closed by the end of the period. We present a simple model of investment in human capital, marital sorting and intergenerational mobility that can rationalize the ?ndings

In the name of the son (and the daughter): intergenerational mobility in the United States, 1850-1940

This paper estimates historical intergenerational elasticities between fathers and children of both sexes in the United States using a novel empirical strategy. The key insight of our approach is that the information about socioeconomic status conveyed by first names can be used to create pseudo-links across generations. We find that both father-son and father-daughter elasticities were flat during the nineteenth century, increased sharply between 1900 and 1920, and declined slightly thereafter. We discuss the role of regional disparities in economic development, trends in inequality and returns to human capital, and the marriage market in explaining these patterns

Simple spatial scaling rules behind complex cities

Although most of wealth and innovation have been the result of human interaction and cooperation, we are not yet able to quantitatively predict the spatial distributions of three main elements of cities: population, roads, and socioeconomic interactions. By a simple model mainly based on spatial attraction and matching growth mechanisms, we reveal that the spatial scaling rules of these three elements are in a consistent framework, which allows us to use any single observation to infer the others. All numerical and theoretical results are consistent with empirical data from ten representative cities. In addition, our model can also provide a general explanation of the origins of the universal super- and sub-linear aggregate scaling laws and accurately predict kilometre-level socioeconomic activity. Our work opens a new avenue for uncovering the evolution of cities in terms of the interplay among urban elements, and it has a broad range of applications.This work is supported by the National Natural Science Foundation of China under Grant Nos. 61673070, 61773069, 71731002 and the Fundamental Research Funds for the Central Universities with the Grant No. 2015KJJCB13, and also partially supported by NSF Grants PHY-1505000, CMMI-1125290, CHE-1213217, DTRA Grant HDTRA1-14-1-0017, DOE Grant DE-AC07-05Id14517.

Universities of the Third Age : a rationale for transformative education in later life

This article addresses the political context of third-age learning. It aims to expose how relations of power and inequality, in their myriad combinations and complexities, are manifest in Universities of the Third Age [U3As]. The dominant functionalist approach towards late-life learning is jettisoned in favor of a socio-political framework that asks: whose interests are really being served? and, who controls the learning process? It highlights the role of U3As in reproducing unequal relations in later life with special emphasis on positive ageism, elitism, gender, and third ageism. The article ends by proposing a possible way forward away from a neo-liberal ideology through a transformative rationale for older adult education based on the values of social justice, social leveling and social cohesion. Seven principles are forwarded: a transformational agenda, widening participation, critical geragogy, elearning, pre-retirement education, intergenerational learning, and fourth age learning.peer-reviewe

Law, Social Movements, and the Political Economy of Domestic Violence

This article uses the occasion of the 2013 Reauthorization of the Violence Against Women Act (VAWA) to review the circumstances by which legal theory and social movement discourse have circumscribed the scope of VAWA and the dominant approach to domestic violence. This article seeks to explore the relationship between domestic violence advocacy and feminist theory, which has functioned as “the ideological reflection of one’s own place in society” with insufficient attention to superstructures. Additionally, it argues for a reexamination of the current domestic violence/criminal justice paradigm and calls for the consideration of economic uncertainty and inequality as a context for gender-based violence. As an epistemology, domestic violence scholarship has fallen behind other fields of study due to its failure to address the structural context of gender-based violence. This article proposes a redefinition of the parameters of domestic violence law and presents new (and provocative) ways to think about law-related interventions to ameliorate gender violence

Crowdsourced Data Mining for Urban Activity: A Review of Data Sources, Applications and Methods

The penetration of devices integrated with location-based services and internet services has generated massive data about the everyday life of citizens and tracked their activities happening in cities. Crowdsourced data, such as social media data, POIs data and collaborative websites, generated by the crowd, has become fine-grained proxy data of urban activity and widely used in research in urban studies. However, due to the heterogeneity of data types of crowdsourced data and the limitation of previous studies mainly focusing on a specific application, a systematic review of crowdsourced data mining for urban activity is still lacking. In order to fill the gap, this paper conducts a literature search in the Web of Science database, selecting 226 highly related papers published between 2013 and 2019. Based on those papers, the review firstly conducts a bibliometric analysis identifying underpinning domains, pivot scholars and papers around this topic. The review also synthesises previous research into three parts: main applications of different data sources and data fusion; application of spatial analysis in mobility patterns, functional areas and event detection; application of socio-demographic and perception analysis in city attractiveness, demographic characteristics and sentiment analysis. The challenges of this type of data are also discussed in the end. This study provides a systematic and current review for both researchers and practitioners interested in the applications of crowdsourced data mining for urban activity.This research is funded by a scholarship from the China Scholarship Counci

Uncovering the socioeconomic facets of human mobility

Given the rapid recent trend of urbanization, a better understanding of how urban infrastructure mediates socioeconomic interactions and economic systems is of vital importance. While the accessibility of location-enabled devices as well as large-scale datasets of human activities, has fueled significant advances in our understanding, there is little agreement on the linkage between socioeconomic status and its influence on movement patterns, in particular, the role of inequality. Here, we analyze a heavily aggregated and anonymized summary of global mobility and investigate the relationships between socioeconomic status and mobility across a hundred cities in the US and Brazil. We uncover two types of relationships, finding either a clear connection or little-to-no interdependencies. The former tend to be characterized by low levels of public transportation usage, inequitable access to basic amenities and services, and segregated clusters of communities in terms of income, with the latter class showing the opposite trends. Our findings provide useful lessons in designing urban habitats that serve the larger interests of all inhabitants irrespective of their economic status.Comment: main manuscript 25 page, 7 Figures.

A Theory of Poverty: Legal Immobility

The puzzle of why the cycle of poverty persists and upward socioeconomic mobility is so difficult has long captivated scholars and the public alike. Yet with all of the attention that has been paid to poverty, the crucial role of the law, particularly state and local law, in perpetuating poverty is largely ignored. This Article offers a new theory of poverty, one that introduces the concept of legal immobility. Legal immobility considers the cumulative effects of state and local laws as a mechanism through which poverty is perpetuated and upward socioeconomic mobility is stunted. The Article provides an initial description and normative account of this under-theorized aspect of our laws and argues that in order to fully understand poverty, a more complete understanding of the relationship between law and poverty is needed. After discussing several examples of laws that can contribute to legal immobility (everything from state and local tax laws to occupational licensing laws), the Article offers a three-prong theory to help understand the distinct pathways through which individual laws that contribute to legal immobility function: (1) calculated exploitation; (2) gratuitous management; and (3) routine neglect. This framework provides a guide for future work to build on legal immobility theory. By bringing to light the cumulative effects of local and state laws in perpetuating poverty, the goal is for legal immobility theory to ultimately help lawmakers develop new structural approaches to tackling poverty
