Credit constraints and the redistribution of housing wealth Staff working papers set out research in progress by our staff, with the aim of encouraging comments and debate.

Staff Working Paper 1147 by B Tracey (BoE) & N van Horen (BoE) shows FTB home purchases rose sharply after 2013 when the deposit requirement was reduced from 10% to 5% by HTB. Gains were concentrated among FTBs unlikely to have relied on family support. ๐Ÿ”— www.bankofengland.co.uk/working-pape...

A Dutch study explores a key barrier to social integration: strong in-group preferences. One hopeful exception: young people donโ€™t have strong preferences for people of their own ethnicity when it comes to sports activities. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

New paper, using conjoint experiments to study ingroup preferences across multiple settings (neighborhoods, civic orgs, sports clubs) and social dimensions (age, ethnicity, education). We also link people's choices in the experiments to the real-world contexts they are embedded in.

In our preprint, @katyaoivanova.bsky.social and I find that environmentalists are less likely to have kids in their 20s and 30s... But by their early 40s, the gap closes.

Is there a religious revival in England?

@sriucl.bsky.social's David Voas raises questions about a recent report claiming that Gen Z is leading a rise in church attendance after decades of religious decline. It appears the devil is in the data.

Research on segregation often points to parental preferences, but what if it's not just about what parents want, but also what options they actually have?

Details of the publication with abstract which reads: Honor killings, which occur when women are perceived to have broken purity norms and bring โ€œdishonorโ€ to their family, pose profound moral and societal problems and underrecognized sociological puzzles. Given the immense cost, why do families murder their own daughter,
niece, or cousin? Conversely, given the tragic consequences, why are norms broken in the first place? Drawing on accounts of honor killings, we characterize the key actors, actions, and incentives, and develop two interlinked theoretical models, one on norm-enforcement
and another on norm-breaking. The former specifies the conditions under which honor norms should hold, the latter, counterintuitively, predicts that honor killings occur most frequently when honor norms are contested; not when they are strictest. Analyzing data from 24 countries and ~26,000 individuals and building a unique dataset of honor killings from Turkey, we find support for the hypotheses. Honor norms are stronger when laws offer leniency for honor killings, familiesโ€™ loss of reputation is more consequential, and community cohesion is higher. Actual killings have an inverse-U-shaped link with the prevalence of honor norms. Our work advances the theoretical understanding of honor norms and killings and offers one of the most
comprehensive empirical analyses of the factors influencing honor killings.

Note: Panel A shows an interaction within a family. Panel B shows the probability of breaking a norm (p2) in the game tree in panel A; the probability of the existence of an honor norm in the repeated norm-enforcement game (p1, i.e., conditions given in Hypotheses 1, 2, and 3 obtain); and the probability of honor killing (p3), which is the product of the former two probabilities, as a function of repeated norm-enforcement game parameters.
