What’s the Melting Pot Worth? Multiculturalism and House Prices

IWH Discussion Papers,
No. 11,
2025
Abstract
Is there a multicultural neighborhood price premium? We exploit plausibly exogenous variation in British colonization patterns in Northern Ireland during the early 1600s which created neighborhoods of varying religious composition that persists until today. These religious groups are culturally distinct, but are observationally equivalent ethnically and socioeconomically. A standard deviation increase neighborhood-level multiculturalism raises house prices by 9.6%. Multiculturalism raises property prices by increasing asset liquidity and housing demand as a wider spectrum of society demand houses in these areas. The findings and mechanism contrast sharply with prior evidence showing negative relationships due to homophily, social networks, and identification challenges.

Uncertainty Holds Back European Economy ‒ Report by AIECE, a Network of European Economic Research Institutes
The AIECE Association of European Economic Research Institutes has today published its bi-annual General Report, following the Spring 2025 Meeting held in Oslo hosted by Statistics Norway. The Halle Institute for Economic Research (IWH) is a long-time member of this network and regularly contributes its economic expertise to the joint analyses and forecasts. On average, AIECE member institutes forecast EU GDP to grow by of 1.2% in 2025 and 1.5% in 2026. The average forecast for Euro Area GDP growth is 1.0% and 1.3%. These forecasts are a bit more optimistic than those presented in the OECD's March 2025 Interim Report and the IMF's Spring 2025 World Economic Outlook.

Social Connections and Information Leakage: Evidence from Target Stock Price Run-up in Takeovers
Iftekhar Hasan, Lin Tong, An Yan
Journal of Financial Research,
Vol. 48 (2),
2025
Abstract
Does information leakage in a target's social networks increase its stock price prior to a merger announcement? Evidence reveals that a target with more social connections indeed experiences a higher pre-announcement price run-up. This effect does not exist during or after the merger announcement, or in windows ending two months before the announcement. It is more pronounced among targets with severe asymmetric information, and weaker when the information about the upcoming merger is publicly available prior to the announcement. It is also weaker in expedited deals such as tender offers.
