Data Cooperatives: Democratic Models for Ethical Data Stewardship

Data cooperatives offer a new model for fair data governance, enabling individuals to collectively control, manage, and benefit from their information while adhering to cooperative principles such as democratic member control, economic participation, and community concern. This paper reviews data cooperatives, distinguishing them from models like data trusts, data commons, and data unions, and defines them based on member ownership, democratic governance, and data sovereignty. It explores applications in sectors like healthcare, agriculture, and construction. Despite their potential, data cooperatives face challenges in coordination, scalability, and member engagement, requiring innovative governance strategies, robust technical systems, and mechanisms to align member interests with cooperative goals. The paper concludes by advocating for data cooperatives as a sustainable, democratic, and ethical model for the future data economy.

A new method for identifying what Cupid's invisible hand is doing. Is it spreading color blindness while turning us more "picky'' about spousal education?

We develop a method suitable for detecting whether racial homophily is on the rise and also whether the economic divide (i.e., the gap between individuals with different education levels and thereby with different abilities to generate income) is growing in a society. We identify these changes with the changing aggregate marital preferences over the partners' race and education level through their effects on the share of inter-racial couples and the share of educationally homogamous couples. These shares are shaped not only by preferences, but also by the distributions of marriageable men and women by traits. The method proposed is designed to control for changes in the trait distributions from one generation to another. By applying the method, we find the economic divide in the US to display a U-curve pattern between 1960 and 2010 followed by its slightly negative trend between 2010 and 2015. The identified trend of racial homophily suggests that the American society has become more and more permissive towards racial intermarriages since 1970. Finally, we refute the aggregate version of the status-cast exchange hypothesis based on the joint dynamics of the economic divide and the racial homophily.
